Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a joint structure for panels used as structural members of assembled underground houses and the like.

(Prior Art) FIGS. 5 and 6 show an example of a conventional joining structure of this type (Japanese Patent Publication No. 54-2372).
In the figure, 1 and 2 are joined bodies, and the joined bodies 1 and 2 are provided with bolt holes 3 at predetermined positions of the joined parts.
Band-shaped sealing materials 4 and 5 are arranged on both sides of the bolt hole 3 and on the joint surfaces thereof. 6 is a sealing material having a bolt hole 7, and the bolt hole 7 is arranged at the position of the bolt hole 3 and between the sealing materials 4 and 5. Then, a bolt 9 is inserted into the bolt hole 3 through the washer 8 from the inside of the joined body 1, and a nut 11 is screwed into the inside of the joined body 2 through the washer 10. , 2 have been concluded.

(Problems to be solved by the invention) However, in such a conventional joint structure, the sealing material 4, which is interposed between the joint surfaces of the joined bodies 1 and 2,
5 and 6 are all highly elastic, so when bolts 9 and nuts 11 are tightened, the amount of tightening is not constant, and if they are not tightened enough, the waterproof performance will be insufficient, and if they are over tightened, the sealing material There is a problem that there is a risk of damaging parts 4, 5, and 6.

This invention was developed to solve the above-mentioned problems, and by always keeping the joint dimensions of the panels constant, and by always setting the compression amount of the caulking material and sealing material to the optimum value, it improves waterproof performance and durability. The purpose is to improve the

(Means for solving the problem) In order to achieve the above-mentioned purpose, in this invention,
A frame is formed with the flange part of the channel material facing inward, a keystone plate is stretched on one side of the frame, a foam insulation board is superimposed on the outer surface of the keystone plate, and the outer surface of this foam insulation board and the frame are Bolt holes are provided at appropriate intervals on each joint surface of a panel formed integrally by covering the outer peripheral surfaces of and a polymeric material with a stainless steel plate, and the bolt holes on one of the joint surfaces of the panels to be joined are provided. A square washer made of a rigid body is attached to the washer, and a belt-shaped sealing material made of an elastic material with a thickness larger than that of the washer is attached at an appropriate interval to the outside of this washer, and a band-shaped sealing material made of an elastic material is attached to the inside of this band-shaped sealing material. A sticky caulking material is attached along the joint surface of the panel, the joint surface is joined to the joint surface of another panel, a bolt is inserted into the bolt hole, and a nut is screwed into the protruding part of the washer. Tighten until pressure is applied to connect the panels.

(Function) Since the present invention is configured as described above, the joint dimensions of the panels can always be kept constant, and the compression amount of the caulking material and sealing material can always be set to the optimum value, thereby improving waterproof performance and durability. can be improved.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. 3 shows an example of an underground house constructed by joining panels according to the present invention, in which a is the bottom, b is the side wall, c is the ceiling, and d is the opening. Reference numeral 20 shown in FIGS. 1, 2, and 4 is a panel that is a component of the panel, and this panel 20 is, for example, a frame made of a channel material 21 with the flange portion 21a facing inward, and a keystone plate is attached to one side of the frame. 22 is stretched, a foam heat insulating board 23 is superimposed on the outer surface of the keystone plate 22, and the outer surface of the foam heat insulating board 23 and the outer peripheral surface of the frame and the polymerized materials 22, 23 are covered with a stainless steel plate 24.
It is coated and formed integrally.

Reference numerals 25 indicate bolt holes provided at appropriate intervals on each joint surface of the panel 20.

In this embodiment, a rectangular washer 26 made of stainless steel is attached to one bolt hole 25 of the joint surfaces of the panels 20, 20 to be joined, and a square washer 26 made of stainless steel is attached at an appropriate interval on the outside of this washer 26. A belt-shaped sealing material 28 made of an elastic material that is thicker than the washer 26 is attached, and a slimy caulking material 2 is applied along the inside of the belt-shaped sealing material 28.
7 is taken out from the tube and attached, and as shown in FIG. Screw together and wash 26
Tighten the panels 20, 20 until they are pinched.
be concluded.

As the caulking material 27, for example, tubed polyurethane resin sealer (manufactured by Auto Kagaku Co., Ltd.) is suitable, and as the sealing material 28, for example, a flexible sealing material such as closed-cell polyvinyl chloride foam is suitable. Are suitable.

Since the joining structure of the panels of the present invention is as described above, when the panels 20, 20 are fastened together with bolts 29 and nuts 30 as shown in FIG. It is always compressed by a certain amount. Since the gap between the joint surfaces of the panels 20 is always constant (thickness of the washer 26), the assembly dimensions can be accurate.

In addition, by setting the thickness of the caulking material 27 and sealing material 28 appropriately, the optimum amount of compression can always be obtained, and since there is no under-tightening or over-tightening, stable and high performance waterproof performance can always be obtained. , there is no risk of damaging the caulking material 27 and the sealing material 28.

In particular, since the caulking material 27 is a sticky substance that is taken out of the tube and attached along the inside of the sealing material 28, the cross-sectional shape becomes wedge-shaped as shown in FIG. As shown in the figure, the excess thickness of the compressed caulking material 27 moves to the inner side. Therefore, there is no risk of damaging the caulking material 27 due to excessive stress.

(Effects of the invention) Therefore, according to the invention, waterproof performance and durability can be improved by always keeping the joint dimensions of the panels constant and by always keeping the compression amount of the caulking material and sealing material at the optimum value. You can get excellent results by being able to do this.
