Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes a male screw member inserted through a through-hole formed between the glass panel and the plate material, and a screw member attached to the male screw member. The present invention relates to a fixing method of a glass panel that is fastened and fixed with a female screw member.
[0002]
[Prior art]
In the fixing method of the glass panel, there is a possibility that the glass panel may be damaged when the tightening force is concentrated on the glass panel or when the through-hole portion of the glass panel strikes the fastening tool.
[0003]
Therefore, conventionally, an elastic sheet such as a resin sheet or a rubber sheet is sandwiched and fixed between the glass panel and the plate material, and the elastic sheet is brought into close contact with both the glass panel and the plate material so that the clamping force is increased. The frictional force acting between the glass panel and the elastic sheet and the frictional force acting between the elastic sheet and the plate material along the plate surface of the glass panel and the plate material. Relative displacement in the direction is prevented, and the strength of the fixed portion can be secured.
[0004]
[Problems to be solved by the invention]
According to the above conventional fixing method, in order to reliably prevent the relative displacement between the glass panel and the plate material, it is necessary to tighten and fix with a strong tightening force to increase the frictional force. If the acting clamping force becomes too strong, the glass panel will be damaged, or the elastic sheet will be excessively compressed and deformed, and the clamping force will be reduced and relative deformation will be prevented due to long-term creep deformation. The frictional force is also reduced, and the proof stress may be reduced.
[0005]
The present invention has been made in view of the above circumstances, and can reliably prevent the relative displacement in the direction along the plate surface of the glass panel and the plate material over a long period of time, thereby improving the yield strength of the fixed portion. The purpose is to be able to.
[0006]
[Means for Solving the Problems]
The characteristic configuration of the invention according to claim 1 is a male screw member in which a glass panel and a plate material applied to the glass panel from the thickness direction are inserted into a through hole formed between the glass panel and the plate material. A glass panel fixing method in which a female screw member screwed to the male screw member is fastened and fixed, which is made of a fiber material impregnated with an uncured adhesive between the glass panel and the plate member. The sheet is clamped and the adhesive is cured, and the glass panel and the plate are bonded and fixed.
[0007]
In other words, a sheet made of a fiber material impregnated with an uncured adhesive is sandwiched and fixed between the glass panel and the plate material, and when the adhesive is cured, the sheet becomes the glass panel and the plate material. of Ri Katama in shape along the both surfaces, via a strong adhesive layer cured into a sheet integrally, and a high glass panels and plate rigidity can be bonded and fixed.
[0008]
Therefore, the glass panel and the plate material can be integrally fixed via the sheet while the sheet is adhered to both the glass panel and the plate material, and the fastening force is dispersed and acted on the glass panel. Relative displacement in the direction along the plate surface between the glass panel and the plate material can be reliably prevented over a long period of time without fixing the glass panel and the plate material with a particularly strong clamping force, thereby improving the proof stress of the fixed part. be able to.
According to a second aspect of the present invention, a plurality of the through holes are formed across the glass panel and the plate member, and the female screw member is screwed into the male screw member inserted into each of the through holes. The glass panel and the plate material are clamped with the sheet interposed therebetween.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
1 shows a frame B made of a tempered glass plate in which a glass wall A made of a large glass plate provided as a part of the outer wall so that the outside can be widely seen from the inside of a building, with a joint seal J interposed therebetween. The reinforcement structure of the glass wall reinforced with is shown.
[0013]
The frame B is formed by connecting up and down a belt-shaped tempered glass plate (hereinafter simply referred to as a glass plate) 1 having a thickness of about 12 to 25 mm as a glass panel by the glass panel fixing method according to the present invention. It is configured.
[0014]
FIG. 2 shows a connection structure between the glass plates 1, and a stainless steel plate having a thickness of about 6 mm to 12 mm as a plate material from both the left and right sides in the thickness direction with respect to the glass plate 1 which is abutted vertically with a gap therebetween. The connection plate 2 made of metal is applied so as to straddle the upper and lower glass plates 1, and the sheet 3 hardened by the curing of the adhesive is sandwiched between the glass plate 1 and the connection plate 2, and these glass plates The glass plate 1 and the connection plate are composed of a male screw member 5 inserted into a through hole 4 formed between the sheet 1, the sheet 3 and the connection plate 2, and a female screw member 6 screwed to both ends of the male screw member 5 separately. 2 is fastened and fixed.
[0015]
The through-hole 4 is formed in the glass plate 1 by continuously communicating the large-diameter holes 1 a and 3 a formed in the glass plate 1 and the sheet 3 and the small-diameter holes 2 a formed in each connection plate 2. A resin bush 7 is fitted into the large-diameter hole 1a.
[0016]
As shown in FIG. 3, the male screw member 5 is composed of a high-strength full screw bolt having a male screw portion 5a formed over its entire length, and a screwdriver D can be engaged with both ends of the screw D so that it can be screwed. An engaging groove 8 is formed.
[0017]
Each of the female screw members 6 includes a cylinder portion 9 that is fitted into the through hole 4 in a state of being fitted on the male screw member 5, and a head that restricts the entry into the through hole 4 by contact with the connection plate 2. 10 is formed on the inner peripheral surface of the cylindrical portion 9, and a female screw portion 6 a that is screwed into the male screw member 5 is formed on the head portion 10. 11 is formed.
[0018]
FIG. 4 shows a procedure for connecting the glass plates 1, the glass plates 1 in which the large-diameter holes 1 a are formed in advance at a predetermined interval are brought into contact with each other, and the sheet 3 in which the large-diameter holes 3 a are formed in the predetermined intervals in advance. It applies so that it may straddle both glass plates 1, and also the connection plate 2 is applied to the sheet | seat 3. FIG.
A bush 7 is fitted in the large-diameter hole 1a of the glass plate 1 in advance.
[0019]
The sheet 3 is made by impregnating a fiber material such as a glass fiber woven fabric, a felt cloth, a nonwoven fabric, or a cellulose plate (a vulcanized fiber plate) with an adhesive such as an epoxy adhesive, an elastic adhesive, or an emulsion latex adhesive. In this configuration, the adhesive is applied to both glass plates 1 in an uncured state, and the connection plate 2 is applied to an uncured sheet 3 of the adhesive.
[0020]
Then, while the adhesive impregnated in the sheet 3 is uncured, the male screw member 5 is inserted into the through-hole 4 and the female screw member 6 is screwed to both ends of the male screw member 5 so that the sheet 3 is a glass plate. After tightening with a predetermined tightening force together with 1 and the connection plate 2, curing is performed until the adhesive is cured.
[0021]
Therefore, when the adhesive is cured, the sheet 3 is solidified in a shape along the surfaces of both the glass plate 1 and the connection plate 2 to form a strong adhesive layer, and the sheet 3 is bonded to the glass plate 1 and the connection plate 2. The glass plate 1 and the connecting plate 2 can be integrally fixed via the sheet 3 while being adhered so as to be in close contact with each other and dispersing and acting on the glass plate 1.
[0022]
FIG. 5 shows a comparison result of relative displacement amounts in the direction along the plate surface of the glass panel 1 and the plate material 2 between the glass panel fixing method of the present invention and the conventional glass panel fixing method. The test method is shown.
[0023]
That is, as shown in FIGS. 6 (a) and 6 (b), a stainless steel plate (thickness 12 mm) 2 as a plate material bolted to the fixing portion F is attached to one side surface of the reinforced plate glass 1 as a glass panel. 3, and a stainless steel backing plate (thickness 12 mm) G is applied to the other side with a similar sheet 3 sandwiched between the glass plate 1, the steel plate 2 and the backing plate G. A stainless steel male screw member (nominal dimension M16, length 32 mm) 5 inserted through the through-hole 4 formed in this way, and a stainless steel female screw member (similar to the above) screwed to the male screw member 5 ( The reinforced plate glass 1 is cantilevered and fixed to the steel plate 2 in a cantilevered manner with a head outer diameter of 30 mm, a tube portion outer diameter of 21 mm, and a tube portion length of 19 mm). Made of bush Outside diameter 25.5 mm, Aru fitted an inner diameter 22 mm) 7.
[0024]
Then, a sheet made of a fiber material impregnated with an uncured adhesive (adhesive mainly composed of vinyl acetate resin emulsion) as a sheet (thickness 1 mm) 3 was used to cure the adhesive. Vertical displacement of the tip when a vertical load W of 0 to 1000 kgf is applied near the tip of the reinforced plate glass 1 for each of the case and the case of using a sheet made of a fiber material not impregnated with an adhesive The amount H was measured.
[0025]
The tempered glass sheet 1 has a length of 1719 mm, a width at the base end of 325 mm, a width at the tip of 244 mm, a thickness of 15 mm, and three male screw members 5 inserted at a pitch of 100 mm. Tightened and fixed.
[0026]
As shown in FIG. 5, when the sheet 3 not impregnated with the adhesive is used, the displacement amount H increases rapidly when the load W exceeds 150 kgf, and the displacement amount H becomes about 21 mm when the load W is 300 kgf. After that, although the rate of increase became gradual, the displacement amount H at 600 kgf, which is the load W immediately before the glass breakage, was about 35 mm.
[0027]
Therefore, when the sheet 3 not impregnated with the adhesive is used, the displacement of the tempered glass sheet 1 is restrained by the frictional force generated by the tightening torque between the male screw member 5 and the female screw member 6 until the load W is near 200 kgf. Thereafter, it is considered that the through-hole portion 1 a of the tempered glass sheet 1 was crushed by the pressing action with the cylindrical portion 9 of the female screw member 6.
[0028]
On the other hand, when the sheet 3 impregnated with the adhesive is used and the adhesive is cured, the displacement H does not increase rapidly but increases at a substantially constant rate, and the load W is 550 kgf. The displacement amount H was about 10 mm, and the displacement amount H of about 24 mm was shown at 1000 kgf which is the load W just before the glass breakage.
[0029]
From this, by hardening the sheet 3 impregnated with the adhesive, the reinforced plate glass 1, the sheet 3, the steel plate 2, and the backing plate G are bonded to each other by the tightening torque between the male screw member 5 and the female screw member 6. It is understood that the relative displacement H is less likely to occur even when the vertical load W is applied and the proof stress is improved.
[0030]
