04, the third engaging portion 123 of the hanger 121, and the first engaging portion 10 of the roof material 101 arranged on the ridge side.
3 and 3.

First, the plate portion 1 in the second engaging portion 104.
The second engaging portion 104 and the third engaging portion 123 are joined so that 11 and 112 fit in the space formed by the plate portions 125 to 128 in the third engaging portion 123. At this time, the plate portion 1 in the second engaging portion 104
10 is in contact with the roof base 131.

Further, the plate portion 1 in the second engaging portion 103
The bent portion between the plate 11 and the plate portion 112 abuts on the bent portion between the plate portion 126 and the plate portion 127 in the third engaging portion 123 (contact portion A1), and the second engaging portion. The bent portion of the plate portion 110 and the plate portion 111 in 103 is the third engaging portion 12

[0014]

However, in the above-mentioned conventional structure, in particular, from the viewpoint of the strength of the joint portion,
The following problems occur.

That is, in the engagement between the second engaging portion 104 and the third engaging portion 123, the fixing is obtained by the contact points A1 and A2 shown in FIG. 8, but the force is small, In particular, almost no force is obtained to fix the third engaging portion 123 in the direction normal to the roof surface. of course,
The third engaging portion 123 is provided with a fixing force in the direction normal to the roof surface by the screwing of the fixing portion 122.
Since it is far away from 22, the fixing force in the normal direction of the roof surface is 3rd in consideration of the bending generated in the sheet metal.
It cannot be said that it sufficiently occurs in the engaging portion 123 of.

Regarding the engagement of the first engaging portion 103, the fixing force in the direction normal to the roof surface is the contact point B.
2, B3, C1. In other words, at the contact point C1, the plate portion 12 of the third engaging portion 123 is
8 presses the plate portion 107 of the first engaging portion 103 to the plate portion 110 side of the second engaging portion 104.

However, if the force for fixing the third engaging portion 123 in the direction normal to the roof surface is weak as described above, the plate portion 128 of the third engaging portion 123 is naturally the first engaging member. The force pressing the plate portion 107 in the joining portion 103 also becomes weak. Therefore, the fixing force of the first engaging portion 103 in the direction normal to the roof surface is not sufficient.

Further, the force for fixing the first engaging portion 103 in the inclination direction of the roof is the contact points B2, B3, C1.
It is also obtained by the frictional force in the above. However, if the plate portion 128 of the third engagement portion 123 pushes the plate portion 107 in the first engagement portion 103 weakly, sufficient frictional force cannot be obtained. Easy to understand.

Therefore, in the above-mentioned conventional structure, the fixing force generated between the first to third engaging portions 103, 104 and 123 at the joining portion of the roofing material 101.101 and the hanger 121 is not sufficient, The strength of the joint cannot be obtained sufficiently.

In recent years, a module such as a solar system panel is placed on the roof, or a snow stopper is installed in the snowy region. In the above-mentioned thatched roof, since the mounting members for mounting these modules on the roof are arranged at the joints, if the strength of the joints is small, the safety of installing the modules cannot be ensured. There is.

At this time, since the fifth plate portion acts as a leaf spring, both ends of the fifth plate portion are urged to the inner space wall surface of the third engaging portion, and the friction at the contact point increases. Thus, it is possible to suppress the slippage between the second engaging portion and the third engaging portion.

Further, the first engaging portion has a third plate portion extending from the eaves side through the first and second plate portions,
The third plate portion is fixed by inserting it from the eaves side between the fourth plate portion of the second engaging portion and the ninth plate portion of the third engaging portion. At this time, since the position of the first engaging portion is maintained by the friction between the third plate portion and the fourth plate portion and the ninth plate portion, the position of the first engaging portion is maintained. The fixing force is maintained by maintaining the gap with the plate portion at an appropriate interval. In addition, the third plate portion and the second

The positional relationship between the second engaging portion and the third engaging portion is firmly fixed by the action of the leaf spring of the fifth plate portion described above, so that the fourth plate portion is fixed. The gap between the second plate and the ninth plate part is maintained at an appropriate interval, and the first engaging part is also fixed to the second engaging part and the third engaging part without causing slippage. can do.

As described above, by suppressing the displacement in the first to third engaging portions and fixing each engaging portion, the strength in the joint portion can be improved.

According to a third aspect of the present invention, there is provided a horizontal thatched roof structure in which a portion between the first engaging portion and the third engaging portion is provided at a joint portion between the lateral thatched roof material and the hanger. It is characterized in that a reinforcing plate having a shape along the outer surfaces of the sixth and seventh plate parts of the third engaging part and the fixing part of the suspension is inserted.

Usually, the horizontal roofing material and the hanging member are formed by bending a sheet metal having a relatively small thickness,
The shape of the joint may change due to an external force. Then, such a shape change becomes a factor that causes a deviation between the first to third engaging portions.

On the other hand, according to the above construction, the sixth and seventh plate portions of the third engaging portion are suspended between the first engaging portion and the third engaging portion. The rigidity of the joint is increased by inserting the reinforcing plate having a shape along the outer surface of the fixed portion of the child, and the change in shape of the joint is suppressed. Therefore, it is possible to prevent the displacement between the first to third engaging portions due to the change in the shape of the joint portion, and it is possible to further improve the strength of the joint portion.

The plate portion 10 is formed as a part of the main plate 2. The plate portion 11 is formed by bending upward at the ridge-side end of the plate portion 10. Here, the angle α formed by the plate portion 10 and the plate portion 11 is an acute angle. Further, the plate portion 11 is not formed as a single flat surface, but has a substantially V-shaped cross section bent at the bending point 11a. The bending point 11a exists on the eaves side of the straight line connecting both ends of the plate portion 11. The plate portion 12 is formed by bending (hanging) downward at the tip of the plate portion 11. Further, the plate portion 12 is provided with a folded-back portion 13 formed by folding the sheet metal outward (at the eaves side) at its tip.

In the structure shown in FIG. 2C, the plate portion 10
The bent portion between the plate portion 11 and the plate portion 11 and the bent portion between the plate portion 11 and the plate portion 12 are gently bent with a rounded shape, but may be bent more acutely. .

When roofing is performed using the roofing material 1, the roof to be constructed is not limited to the roofing material 1 alone, but a so-called hanging member for fixing the roofing material 1 to the roof substrate. Such members are used. The shape of the suspension is shown in FIG.

As shown in FIG. 3, the suspension 21 has the same cross-sectional shape orthogonal to the axis parallel to the roof ridge direction.
Is mounted on the upper part of the hanging part 21, a fixing part 22 for fixing the tongue to the roof substrate, a third engaging part 23 forming a joint part together with the first and second engaging parts 3 and 4 in the roofing material 1. The support part 24 for supporting the placed roofing material 1 is provided.

The fixing portion 22 is formed in the shape of a single flat plate, and comes into contact with the roof base surface during assembly.

The third engaging portion 23 is formed on the eaves side of the suspension 21 and is composed of the plate portions 25 to 28 and is formed so that its cross section has a substantially square V shape. Has been done. That is, the plate portion 25 is formed by being bent upward from the eaves side end portion of the fixed portion 22, and the plate portion 26 is formed by being bent from the upper end of the plate portion 25 to the eaves side,
The plate part 27 is formed by bending downward from the eaves side end of the plate part 26, and the plate part 28 is formed by bending the ridge from the lower end of the plate part 27.

The length of the plate portion 28 along the inclination direction of the roof is shorter than the distance from the lower end of the plate portion 25 to the lower end of the plate portion 27. Further, the plate portion 28 is formed so as to be parallel to the roof surface, but when the suspension 21 is fixed to the roof, a gap is formed between the plate portion 28 and the roof surface. There is.

Here, the structure of a side-roofing roof constituted by the roofing material 1 ... And the suspenders 21 ... will be described with reference to FIGS.

The two roofing materials 1 to be joined are mounted in the order that the roofing material 1 arranged on the eaves side is mounted and then the suspension 21 and the roofing material 1 on the ridge side. . Specifically, the third engaging portion 23 of the suspension 21 is engaged with the second engaging portion 4 of the roof material 1 on the eaves side. At this time, the plate portions 11 and 12 of the second engaging portion 4 are replaced by the plate portions 25 to 2 of the third engaging portion 23.
The second engaging portion 4 and the third engaging portion 23 are joined so as to fit in the space formed by 8. At this time, the second
The plate portion 10 in the engaging portion 4 of is in contact with the roof base 31.

The fixed portion 22 of the suspension 21 is also in contact with the roof base 31, and the fixed portion 22 is fixed to the roof base 31.
The hanger 21 is fixed by fixing it with screws.

When joining the second engaging portion 4 and the third engaging portion 23, as shown in FIG. 1, the second engaging portion 3 is joined.
The bent portion of the plate portion 11 and the plate portion 12 in the contact with the plate portions 26 and 27 in the third engaging portion 23 (contact portion A
1) and the bent portion between the plate portion 10 and the plate portion 12 in the second engaging portion 3 is the plate portion 25 in the third engaging portion 23.
By making contact with the contact portion (contact portion A2), the positional relationship between the second engaging portion 3 and the third engaging portion 23 is fixed. Further, the folded-back portion 13 formed on the plate portion 12 is in contact with the inner surface side of the plate portion 27 (contact portion A3).

The plate portion 11 between the contact points A1 and A2 is bent at the bending point 11a. Therefore, the plate portion 11 acts as a plate spring. By causing the plate portion 11 to act as a leaf spring, the elastic force of the plate portion 11 is used to apply a biasing force at the contact points A1 to A3 of the second engaging portion 4 and the third engaging portion 23. be able to.

That is, the third engaging portion 23 contacts the contact point A.
1 to A3 (in particular, contact points A1 and A3
2), the elastic force of the plate portion 11 causes the second engaging portion 4
The friction acting between the third engaging portion 23 and the second engaging portion 4 is increased due to the urging of the third engaging portion 23 and the second engaging portion 4. By increasing this friction, slippage between the third engaging portion 23 and the second engaging portion 4 is suppressed, and the third engaging portion 23 and the second engaging portion 4 are separated from each other. Securely fixed to each other.

The main plate 2 of the roofing material 1 is inclined with respect to the roof substrate surface and does not contact the roof substrate 31, as shown in FIG. Therefore, the main plate 2 is supported by being placed on the upper surface of the support portion 24 of the suspension 21.

In the state where the second engaging portion 3 and the third engaging portion 23 are combined, as shown in FIG.
A gap is created between the plate portion 10 of the second engaging portion 3 and the plate portion 28 of the third engaging portion 23. Then, the joint portion is formed by inserting the plate portion 8 of the first engaging portion 3 of the roof material 1 joined to the ridge side into this gap.

At this time, the tip of the plate portion 7 abuts on the inner surface side of the plate portion 11 in the second engaging portion 4 (abutting point B1), whereby the position of the first engaging portion 3 is changed. Is fixed. Further, the plate portion 7 has a plate portion 28 in the third engaging portion 23.
The upper surface of the second engaging portion 4 is in contact with the plate portion 10 of the second engaging portion 4 (the contact portion C1). B2 and B3).

Since the plate portion 7 is lifted by the folded-back portion 8 and the protruding portion 9, a gap is formed between the plate portion 7 and the plate portion 10. Therefore, due to the bending elasticity of the plate portion 7, an urging force is obtained at the contact points B2, B3, and C1, and the urging force increases the frictional force. The frictional force generated at the contact points B2, B3, and C1 suppresses the displacement of the first engaging portion 3.

In order to suppress the displacement of the first engaging portion 3 as described above, the contact point B2.
It is necessary to obtain an appropriate biasing force in B3 and C1. Then, in order to obtain this urging force, the gap between the plate portion 28 and the plate portion 10 must be appropriately maintained.

In the above structure, the gap between the plate portion 28 and the plate portion 10 is deviated because the third engaging portion 23 and the second engaging portion 4 are firmly fixed to each other. (The gap is not widened), the sufficient urging force and the frictional force generated by the urging force are obtained, and the first engaging portion 3 is held without displacement. .

Further, as a modified example of the joint portion of the roof material, it is possible to adopt a structure as shown in FIG. Incidentally, FIG.
Shows an example of mounting a mounting bracket for a module (solar panel or the like) or a snow stopper at the joint.

In the example shown in FIG. 5, the reinforcing plate 41 is inserted between the third engaging portion 23 and the first engaging portion 3. The reinforcing plate 41 is composed of a plate portion 42, a plate portion 43, and a plate portion 44.

The plate portion 42 of the reinforcing plate 41 is sandwiched between the plate portion 26 of the third engaging portion 23 and the plate portion 5 of the first engaging portion 3. The plate portion 43 is in contact with the outer surface (ridge-side surface) of the plate portion 25 in the third engagement portion 23. The plate portion 44 is the fixed portion 2 of the suspension 21.
It touches the upper surface of 2. The reinforcing plate 41 is fixed to the roof base by screws, for example.

Since the roof member 1 and the hanging members 21 are made of sheet metal which is relatively thin in comparison with the size thereof, the rigidity is not so high, and the shape changes such that the inclination of each plate portion changes easily. . The change in shape of the first to third engaging portions 3, 4, and 23 causes a deviation between the first to third engaging portions 3, 4, and 23, so that the strength of the joint portion is increased. Lower. In addition, the roof material 1 and the suspension 2
It is not preferable to increase the plate thickness in order to increase the rigidity of No. 1 because it lowers the workability in assembling the roof and increases the weight of the roof.

In particular, when a module such as a solar panel or a snow stopper is installed on a horizontal thatched roof as in the present invention, the mounting bracket for the module or the snow stopper is attached at the joint. Further, conventionally, there has been a problem that the joining portion is apt to be deformed due to a tightening force when the fittings are attached to the joining portion.

On the other hand, in the structure shown in FIG. 5, the rigidity of the joint is improved by arranging the reinforcing plate 41.
Since the shape of the joint is prevented from changing, the strength of the joint can be stably obtained. This makes it possible to improve the holding force particularly when mounting the module mounting bracket or the snow retaining bracket at the joint.

More specifically, the mounting bracket 50 shown in FIG.
Has a substantially U-shaped cross-sectional shape, and the tip of the bottom plate portion 51 in contact with the roof surface has the plate portion 7 in the first engaging portion 3.
And the plate portion 10 of the second engaging portion 4 are inserted. Further, the top plate portion 52 of the mounting member 50 is configured to press the plate portion 5 of the first engaging portion 3 from the upper surface at the tip thereof.

In the example of FIG. 5, the hanging portion 52a is provided by bending the tip of the top plate portion 52 downward, and the hanging portion 5a is provided.
The tip of 2a is in contact with the ridge 5a provided on the plate 5 of the first engaging portion 3. As a result, the mounting member 50 can be positioned and the holding force of the mounting member 50 can be improved by fitting the hanging portion 52a into the recess of the protrusion 5a.

The bottom plate portion 51 and the top plate portion 5 of the mounting bracket 50.
A screw portion 53, the bottom portion of which is fixed to the bottom plate portion 51, is provided between the two and 2, and the screw portion 53 is provided so as to penetrate the top plate portion 52. A pressing plate 54 and a bolt 55 are attached to the screw portion 53 on the upper surface side of the top plate portion 52. By tightening the bolt 55, the hanging portion 52a of the top plate portion 52 is pressed against the ridge 5a. Force (direction of arrow Z in the figure) acts.

That is, by tightening the bolts 55, the bottom plate portion 51 and the top plate portion 52 of the mounting bracket 50 are fixed.
A force for tightening the joint portion acts between and, and the fitting 50 is fixed by this tightening force. At this time,
If the reinforcing plate 41 does not exist in the joint portion, the tightening force causes deformation of the joint portion, resulting in displacement of the joint portion and reduction in holding force of the mounting bracket 50.
