Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closing structure for closing a gap formed between a cover placed on a structural body and the structural body, and a sealing material used for the closing structure. It can be used as a handrail wall, a waist wall, a parapet, and a structure body to be covered with a cover such as a building foundation or a fence.

[0002]

BACKGROUND ART On the upper surface of a balcony handrail wall formed in the shape of a jetty in a building such as an apartment house, a cover as a top cover of the handrail wall serving as a structural body is covered.
The cap has a side surface facing the side surface of the handrail wall. The cap is attached to the handrail wall via a bracket fixed to the upper surface of the handrail wall, and the length of this bracket is larger than the thickness dimension of the handrail wall. The length protrudes from both sides. For this reason, when attaching a cover to a handrail wall using such a bracket, a gap is formed between the side surface of the cover and the side surface of the handrail wall.

[0003] Even if such a gap is formed between the side of the heddle and the side of the handrail wall, rainwater during normal rain flows from the upper part of the heddle along the side and drops as it is. However, rainwater does not enter the inside of the casket and ride on the upper surface of the bracket or enter the interior of the handrail wall. For this reason, the bamboo barrier is sufficient for the normal waterproofness of the handrail wall.

[0004]

However, during rainy weather accompanied by a storm such as a typhoon, rainwater may blow up along the side surface of the handrail wall. In such a case, it is conceivable that rainwater may enter the inside of the cap tree from the gap even if the gap between the side portion of the cap tree and the side surface of the handrail wall is open downward. For this reason, a structure that can ensure the waterproofness of the handrail wall is desired even in such a case, and the need for such a high degree of waterproofing is particularly increased when the handrail wall is made of wood.

On the other hand, in order to prevent rainwater from entering the inside of the cap, it is sufficient to fill the gap with a sealant and completely close it. However, according to this, the air permeability inside the cap is impaired, and the durability of a handrail wall or the like is affected, which is not preferable.

SUMMARY OF THE INVENTION An object of the present invention is to allow a gap between a cover, such as a cover, and a structural body, such as a handrail wall, to be covered by the cover to secure air permeability and to be closed. An object of the present invention is to provide a structure for closing a gap of a structure body cover that satisfies both waterproofness and air permeability, and a material for closing the gap.

[0007]

According to the present invention, there is provided a structure for closing a gap of a structural body cover according to the present invention, wherein a cover is put on a front end surface of a structural body having a jetty shape, and a side portion of the cover is formed on the structural body. While facing the side surface of the skeleton with a gap, a closing material is arranged in this gap while leaving a ventilation portion between at least one of the side portion of the cover and the side surface of the structure skeleton. It is characterized by having.

According to this structure for closing the gap of the structure body cover, the gap formed between the side surface of the cover and the side surface of the structure body is closed by the closing material, so that waterproofness can be secured.
In addition, the sealing material does not completely close the gap, but leaves a ventilation portion between at least one of the side surface of the cover and the side surface of the structural body. Can also be secured.

In this structure for closing the gap of the structural body cover, the closing material may or may not have air permeability. Further, the plugging material may be composed of respective portions having these properties, and two types of plugging materials having these properties may be used side by side in the gap closing structure of the structure body cover.

In the structure for closing a gap of a structure body cover according to the present invention, a cover is put on a tip surface of a structure body having a jetty shape, and a side portion of the cover is in contact with a side surface of the structure body. The air conditioner is characterized in that it faces each other with a gap, and a sealing material having air permeability is arranged in the gap.

According to the structure for closing the gap of the structural body cover, since the air-permeable closing material is disposed in the gap formed between the side surface of the cover and the side surface of the structural body, the waterproofness of the gap is reduced. It can be secured by the arrangement of materials
The air permeability of the gap can be secured by the air permeability of the closing material itself.

In this structure for closing the gap of the structure body cover, the closing material may be disposed in the gap without leaving a ventilation portion for both the side surface of the cover and the side surface of the structure body. May be disposed in the gap while leaving a ventilation portion between at least one of the side surface portion of the structure body and the side surface of the structural body.

In the above structure for closing the gap of the structural body cover, if the closing material has air permeability, the closing material may be a porous material such as a foamed resin or a sponge. Alternatively, it may be a hairy body formed of resin hair, animal hair, or the like, that is, mohair or the like.

In each of the structures for closing the gap of the structure body cover, the closing material is disposed in the gap between the side face of the cover and the side face of the structure body while leaving a ventilation part between the side face of the cover. And, when a bent portion bent toward the structure body side is formed at the end of the side portion of the cover,
The closing material may be separated from the bent portion in the direction in which the ridge-shaped structure body projects, and may overlap in the thickness direction of the structure body.

In this case, the air permeability of the gap is
It is ensured by a ventilation portion formed between the blocking material and the side portion of the cover, and a ventilation path formed by an interval between the blocking material and the bent portion in the projecting direction of the structural body. Since the air passages overlap in the thickness direction of the structural body, the air passage can be formed to meander in the thickness direction of the structural body.

According to this, the intrusion of rainwater into the inside of the cover can be more effectively prevented by the meandering air passage, and the waterproofness of the structural body by the cover and the blocking material can be enhanced.

According to the present invention, a gap closing material for a structure body cover is provided in a gap between a side surface portion of the cover, which is placed on a tip end surface of the structure body having a jetty shape, and a side surface of the structure body. A ventilation portion is provided between at least one of the side surface of the cover and the side surface of the structure body.

According to the gap closing material for the structure body cover, since the gap closing material is disposed in the gap between the side surface of the cover and the side face of the structure body, waterproofness of the gap can be ensured and the sealing material can be secured. Since the arrangement is performed while leaving a ventilation portion between at least one of the side surface portion of the cover and the side surface of the structure body, the air permeability of the gap can be ensured.

In the gap closing material for the structural body cover, the closing material may or may not have air permeability. In addition, the plugging material may be composed of each part having these properties, and by using two types of plugging materials having these properties in parallel, the waterproofness and the air permeability between the structural body and the cover can be obtained. May be secured and closed.

Further, the gap closing material of the structural body cover according to the present invention is a gap between the side face of the cover which is put on the front end face of the structural body having a jetty shape and the side face of the structural body. And air permeability.

Since the gap closing material of the structural body cover is also arranged in the gap between the side surface of the cover and the side face of the structural body, waterproofness of the gap can be ensured, and this sealing material can be used. Since the film itself has air permeability, the air permeability of the gap can be ensured by the air permeability.

In the gap closing material for the structure body cover, the closing material may be arranged in the gap without leaving a ventilation portion for both the side surface of the cover and the side surface of the structure body. It may be arranged in the above-mentioned gap, leaving a ventilation part between at least one of the side surface of the cover and the side surface of the structural body.

In the above-mentioned gap closing material of the structural body cover, when the closing material has air permeability, the closing material is formed of a porous material such as a foamed resin or a sponge. It may be formed of a polychaete body such as resin hair or animal hair, that is, mohair or the like.

In each of the gap closing members of the structural body cover, the closing member may be attached to the side of the cover, may be attached to the side of the structural body, or may be attached to the side of the cover. It may be both attached to the side of the structural body.

When the cover is attached to the side surface of the cover, it is preferable to attach the cover in advance to the side surface of the cover before the cover is put on the front end surface of the structural body.

As described above, if the covering material is previously attached to the side surface of the cover before the cover is put on the front end surface of the structural body, the work of attaching the cover to the front end surface of the structural body is performed. The plugging material can be naturally arranged in the gap between the side surface and the side surface of the structural body, and this arranging operation can be facilitated.

In the above structure for closing the gap of the structure body cover and the closing material according to the present invention, the structure body may be, for example, a handrail wall of a building, a waist wall, a parapet, or a building foundation. Any type may be used, as long as it is a fence, a jetty, and a cover such as a shade can be put on the tip end surface.

When the structural body is a railing wall or a lumbar wall of a building, the railing wall or the lumbar wall may form a balcony or an outer staircase. A structure other than a building, for example, a structure forming a pedestrian bridge may be used.

Further, the jetty-shaped structure body whose top surface is covered with a cover may protrude upward, may protrude horizontally, or protrude in a direction inclined with respect to these directions. May be. The tip surface of the structural body may be a horizontal surface, a vertical surface, or a surface inclined with respect to these surfaces. Further, the distal end surface of the structural body may be an acute or obtuse curved surface or a curved surface.

The side surface of the cover and the side surface of the structural body facing the side surface may be a surface extending in the longitudinal direction of the structural body, or may be a surface forming an angle such as a right angle with the longitudinal direction. Further, the side surfaces of these covers and the side surfaces of the structural body may be vertical surfaces or surfaces inclined with respect to the vertical direction.

The structural body may be made of wood, concrete, or metal, and may be formed by combining at least two of them.
Any material may be used.

The reason why a gap is formed between the side face of the cover and the side face of the structure body when the structure for closing the gap of the structure body cover according to the present invention and the sealing material is applied is as follows.
Optional.

When the structural body is a handrail wall and the cover is a cover, there is a gap between the side of the cover and the side of the handrail because the handrail is located on the upper surface of the handrail wall. This is because brackets having a length protruding from both side surfaces of the handrail wall are fixed, and the cap is attached to the upper surface of the handrail wall via the bracket. The gap is caused by the protrusion of the bracket from the side surface of the handrail wall. Can be done because of the length.

When a cover such as a cap is attached to a structural body such as a handrail wall via an intermediate member such as a bracket, the covering material is partially or intermittently except for the location of the intermediate member. And may be continuously arranged including the arrangement position of the intermediate member.

The structure for closing the gap of the structural body cover according to the present invention and the material for closing the gap can of course be applied to a case where the cover is attached to the structural body without using an intermediate member such as a bracket.

Thus, the handrail wall 1 meanders in the thickness direction. For this reason, along with the storm, rainwater flows into this ventilation passage 29,
The rainwater cannot enter the inside of the cap 10 through the ventilation portion 28, and the rainwater is blocked by the bent portion 10 </ b> D and the extension 25 and falls downward, and does not enter the inside of the cap 10.

Therefore, even if there is a gap S between the side surface 1A of the handrail wall 1 and the side surface portion 10B of the coping 10, the waterproofness of the gap S can be ensured.

On the other hand, when the weather is fine, the inside of the cover 10 communicates with the outside of the cover 10 through the opening 22D and the hole 22B of the covering member 20 and the ventilation section 28 through the ventilation path 29. Is secured. Therefore, when the weather is fine, the moisture and the like evaporated from the inside of the handrail wall 1 can be discharged to the outside of the coping 10, and the durability of the handrail wall 1 and the like can be improved.

Next, various closing members according to other embodiments of the present invention will be described. These closing members have a length that is continuous in the longitudinal direction of the handrail wall 1 like the closing member of the above-described embodiment.

The closing member 3 according to the second embodiment shown in FIG.
Reference numeral 0 denotes a closing member main body 31 and a hanging member 32 that is vertically provided from a lower end of the closing member main body 31. The closing material body 31
A plate-like mounting portion 31A fixed to a side surface 1A of the handrail wall 1 with a fastening member 37 via a sealing member 36;
1A is formed of an angle material including a horizontally extending portion 31B extending horizontally from the lower end to the side portion 10B side of the coping 10;
A hanging member 32 is hung from the tip of the horizontal extending portion 31B, and the hanging member 32 is made of a flexible elastic material such as rubber or soft synthetic resin. There is an interval between the lower end of the hanging member 32 and the bent portion 10D of the coping 10.

The horizontal extending portion 31B of the closing member body 31
The tip of the hanging member 32 and the position of the hanging member 32 are
B is a position where the ventilation portion 38 is left.

In this embodiment, when a strong wind blows up along the side surface 1A of the handrail wall 1 during rainy weather accompanied by a storm, the hanging wind causes the hanging member 32 to center on the upper end which is a connection portion with the plugging material body 31. It turns to the side part 10B side of the coping 10. As a result, the tip of the hanging member 32 is
In the place where is not arranged, the side portion 10B
And at the place where the bracket 6 is disposed, it contacts the inner surface of the lower extension 6C of the bracket 6.
As a result, even if the rainwater tries to invade the inside of the cap 10 together with the strong wind, the intrusion is caused by the hanging member 32 rotating in this way and the side portion 10B of the cap 10 and the side 1A of the handrail wall 1. This is blocked by the horizontally extending portion 31B of the closing member main body 31 disposed in the gap S, and the waterproofness of the gap S is ensured.

On the other hand, when the weather is fine, the inside and outside of the cover 10 are in communication with each other through the ventilation section 38, so that the ventilation is ensured as in the first embodiment.

FIG. 5 shows a closing member 40 according to the third embodiment.
It is shown. The closing member 40 has a plate-shaped mounting portion 40A fixed to the side surface 1A of the handrail wall 1 with a fastening member 47 via a sealing member 46, and a side portion 10B side of the coping 10 from the lower end of the mounting portion 40A. Horizontal extension 40 extending horizontally to

Further, the horizontal extending portion 40B is slightly separated from the bent portion 10D of the coping 10 upward, which is the projecting direction of the handrail wall 1, and overlaps in the thickness direction of the handrail wall 1. ing. For this reason, the ventilation path 49 extending from the gap S at the height position of the bent portion 10D to the ventilation portion 48 is meandering in the thickness direction of the handrail wall 1.

When rainwater blows up along with the strong wind along the side surface 1A of the handrail wall 1 in the rainy weather accompanied by a storm, the rainwater is applied to the side surface portion 10B of the coping 10 and the handrail wall 1A.
Blocking member 40 arranged in the gap S between the side surface 1A
Of the handrail wall 1 is interrupted by the horizontal extension portion 40B of the handrail, and the ventilation path 49 reaching the ventilation section 48 is meandering in the thickness direction of the handrail wall 1. Therefore, rainwater passes through the ventilation path 49 and the ventilation section 48. Intrusion into the inside of the cap 10 is also prevented, and waterproofness is ensured.

When the weather is fine, the inside and outside of the cover 10 communicate with the ventilation section 48 through the ventilation path 49.
Breathability is ensured.

FIG. 6 shows a closing member 50 according to the fourth embodiment. The closing member 50 is formed of a porous material having elasticity by a foamed resin, a sponge, or the like. Therefore, the closing member 50 has air permeability by itself. The closing material 50 is attached to the inner surface of the side surface portion 10B of the cap 10 using an adhesive or the like before the cap 10 is put on the upper surface of the handrail wall 1. Also,
The natural dimension of the handrail wall 1 in the thickness direction of the closing material 50 is set to be larger than the dimension from the inner surface of the side surface portion 10B of the coping 10 to the side surface 1A of the handrail wall 1. For this reason, if the cap 10 is placed on the handrail wall 1 from above and attached to the handrail wall 1 with the bracket 6, the end of the closing material 50 on the handrail wall 1 side may be a hand at a place where the bracket 6 is not disposed. The closing member 50 is slightly compressed and deformed by the elastic contact of the side surface 1A of the sliding wall 1, and the closing member 50 is pressed against the outer surface of the lower extension 6C of the bracket 6 at the position where the bracket 6 is disposed. Large compression deformation.

When rainwater blows up along the side surface 1A of the handrail wall 1 in rainy weather accompanied by a storm, the side portion 10B of the coping 10 and the side surface 1A of the handrail wall 1 are formed at places where the bracket 6 is not disposed. Since the gap S between them is closed by the closing material 50, the rainwater does not reach a higher position than the bracket 6, and at the place where the bracket 6 is arranged, the rainwater flows downward 6C of the bracket 6. , The upper part of which is blocked by the main body 6A of the bracket 6 protruding from the side surface 1A of the handrail wall 1, so that rainwater can reach a higher position than the bracket 6 even at this point. Absent. Therefore, the side surface portion 10B of the cap 10 and the handrail wall 1
Of the bracket 6 at a position higher than the main body 6A of the bracket 6, waterproofness is secured.

On the other hand, when the weather is fine, the closing material 50 itself is formed of a porous body having air permeability.
Air permeability between the inside of the coping 10 and the outside of the coping 10 in the space above is secured.

Further, according to this embodiment, the closing material 50
Is fixed to the inner surface of the side portion 10B of the cap 10 before the cap 10 is attached to the handrail wall 1.
By performing the operation of attaching the “0” to the handrail wall 1 via the bracket 6, the closing material 50 is naturally disposed at a predetermined position, and this disposing operation of the closing material 50 can be easily performed.

FIGS. 7 and 8 show a closing member 60 according to a fifth embodiment. The closing member 60 is attached to the side surface 1A of the handrail wall 1 via a sealing member 66 with a fastening member 67 via a plate-like mounting portion 61, and from the lower end of the mounting portion 61 to the side surface portion 10B side of the coping 10. The protruding portion 62 is formed of an elastic material such as rubber or soft synthetic resin.

FIG. 7 shows a case in which the distance between the side surface portion 10B of the cap 10 and the side surface 1A of the handrail wall 1 is large L1. In this case, the tip of the protruding portion 62 is
In other words, it does not reach the side surface portion 10B of the bracket 6, but reaches the lower extension 6C of the bracket 6.

In FIG. 7, most of the gap S in the direction of the space between the side surface portion 10 B of the cover 10 and the side surface 1 A of the handrail wall 1 is closed by the protrusion 62 of the closing member 60. Since the protrusion 62, which is separated upward from the bent portion 10D, overlaps the bent portion 10D in the thickness direction of the handrail wall 1, rainwater blows up along the side surface 1A of the handrail wall 1. However, this rainwater that blows up along the side surface 1A at a position closer to the handrail wall 1 than the bent portion 10D is
It is prevented from rising to a position higher than the protrusion 62. Therefore, waterproofness of the gap S at a position higher than the protruding portion 62 is ensured.

On the other hand, when the weather is fine, the protrusion 6
Since the ventilation portion 68 is left inside the side surface portion 10B of the coping 10 where the tip of 2 does not reach, the ventilation of the coping 10 is ensured by the ventilation portion 68.

FIG. 12 is a vertical cross-sectional view of the handrail wall 1 and the cap 10 at a position where the bracket 6 is not arranged.

In this embodiment, the work of attaching the coping 10 to the upper surface of the handrail wall 1 via the bracket 6 is performed while compressing and deforming the closing material 90 at the upper extension 6B of the bracket 6. After this mounting work, the lower corner of the closing material 90 on the side of the handrail wall 1 is located at the side where the bracket 6 shown in FIG.
Elastic contact is made with the upper surface of the handrail wall 1 at the position where the bracket 6 shown in FIG.

When rainwater blows up along the side surface 1A of the handrail wall 1 during rainy weather accompanied by a storm, the upper part of the gap S near the upper surface of the handrail wall 1 is formed at the place where the bracket 6 is not disposed. Since it is closed by the closing material 90, rainwater does not enter the upper surface of the handrail wall 1, and at the place where the bracket 6 is disposed, the side of the side wall 1 </ b> A of the handrail wall 1 and the main body of the bracket 6. Because 6A is protruding,
The rainwater is prevented from reaching the upper surface of the handrail wall 1 by the main body 6A, and the waterproof property is secured.

On the other hand, when the weather is fine, the closing material 90 is made of a porous material and has a breathability by itself.
