Description

[Detailed Description of the Invention] This invention relates to a connecting structure for surface structural members, and in particular to a connecting structure for surface structural members that can be extremely easily constructed using metal plates for the roof or outer wall of a building or structure.

In the case of constructing a roof or an external wall, the present applicant has already proposed a waste board that connects the joints of adjacent left and right surface structural members laid at the same height position, and a structure that is assembled approximately at the center of the above-mentioned waste board. This paper proposes a connection structure in which a pair of surface structure members installed on the left and right sides are joined together using a support member made of a metal material.

This structure is manufactured by bending, folding, pressing, etc. so that both the waste board and the supporting member are assembled with each other, and when attached together, there is no need for screws or welding materials as attachment parts. Although this method has the advantage of greatly simplifying the work, it requires many processing steps and has disadvantages in terms of rain clearance and on-site workability.

This invention was devised in view of these shortcomings.
Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

When constructing the outer wall of a building, the waste board 1 is generally shown in Figure 1A.
, As shown in H, among the metal surface structure materials 3 laid on the outer surface of the base portion 2..., the joint portion of a pair of adjacent left and right surface structure materials 3°3 laid at the same height. used for.

As shown in FIG. 2, this waste board 1 is shaped as an extrusion molded product of aluminum or the like, and has fitting parts 4 and 5 bent outward at its upper end and inward at its lower end. The upper end fitting part 4 has an engaging part 6 provided on the upper edge of the surface structure material 3 from the inside.
A locking portion 7 provided at the lower end of the surface structure member 3 is fitted into the lower end fitting portion 5 from the outside.

Further, a support part 8 whose left and right extending portions are sandwiched pieces 8a, 8a is located approximately at the center shaft along the vertical direction of the waste board 1, and left and right flat parts at the base of this support part 8 are located. On the surfaces of 9, 9, protruding ridges 10 are provided at appropriate intervals.
・is formality.

The above-mentioned pinch pieces 8a, 8a of the support part 8 are different from the flat part 9.
It has parallel groove-shaped insertion parts 11.11 on the left and right between the lower surface and the upper surface of the waste plate, with openings in the vertical and lateral directions.

This waste board 1 is a long molded product made of aluminum or the like with a supporting part 8 and protruding ridges 10 formed thereon, and then cut to a desired length with the upper end facing outward and the lower end facing outward. It is made by bending it inward and then removing some of the unnecessary supporting parts 8 at the top and bottom.

In addition, the cover 12 to be fitted to the support part 8 of the waste board 1 is formed from a metal plate, and a U-shaped fitting part 13 is formed by folding inward at the lower end to lock the lower edge of the surface structure member 3. The cover 12 is fitted on the left and right sides of the cover 12 with folded pieces 14, 14 which are open at the top, and fitted onto the support section 8 from below.

In order to connect the joint part of the left and right pair of surface structure members 3, 3 laid at the same height position using the above-mentioned scrap board and cover,
As shown in Fig. 3 and Fig. 4, the left and right surface structure members 3, 3
along the top of the waste board 1, fit the upper edge engaging parts 6, 6 inside the upper end fitting part 4 of the waste board 1, and fit the lower edge locking parts 7, 7 into the lower end of the waste board 1. While fitting into the outer side of the joint part 5, the edge of the surface structure member is fitted into the insertion part 11.11 of the support part 8 from the lateral direction.

Basically, this completes the connection of the surface structure members 3, 3, but considering the appearance of the connection part, next, insert the folded pieces 14, 14 of the cover 12 from below the support part 8. 11.1
1, push it up, and attach the surface structure member 3 with the lower end fitting part 13.
, 3 from the outside.

The guide bar 12 may be fitted to the support part in advance to a certain extent, and after the edge of the surface structure material is fully inserted into each insertion part, the cover may be fully fitted to the support part.

Since the present invention has the above-described configuration, the upper end fitting part 4 of the waste board 1 fits into the upper edge engaging parts 6, 6 of the surface structure members 3, 3, so that rainwater flowing in from the joint part of the surface structure members can be removed. Even if it reaches the surface of the waste board, it does not flow upwards from the upper end fitting part of the waste board.

Also, the folding piece 14 of the cover 12 in the insertion part 11.11,
14. The edges of the surface structure member 3°3 are the pincers 8a, 8 of the support part 8.
Since it is held between the parts a, the support is strong and the intrusion of rainwater etc. is prevented.

In particular, if an adhesive layer 15 made of a synthetic resin such as urethane is provided on the back surface of the surface structure members 3, 3, the material can provide elastic support without changing over time.

Furthermore, since the end edges of the left and right surface structural members can be connected by simply inserting them into the respective insertion portions, even if the surface structural materials expand and contract due to seasonal changes in temperature, the expansion and contraction can be absorbed within the respective insertion portions.

Therefore, even if the surface structure material stretches, it will not warp or bend, and even if it contracts, it will not come off the support part.
Can withstand long-term use.

Furthermore, when working at a construction site, if the length of the surface structure material is not appropriate, the edge can be cut at a right angle S to the length direction and fitted into the insertion part of the support, making the work easier. The process is extremely simple, and even inexperienced workers can quickly connect the surface structure members.
