Description

Description: TECHNICAL FIELD The present invention relates to a surface structure that constitutes a roof, an outer wall, or the like of a building.

(Prior Art) A conventional structure for a structure will be described by taking a vertical roof as an example.

The inventor of the present invention was proposed by Japanese Patent Application No. 1-173105 (Japanese Patent Laid-Open No.
No. 2), the side edges of the suspension are supported and fixed on the frame-side fixing member, and a groove is formed in the widthwise central portion of the upwardly protruding support formed between the both sides of the suspension. An inner gutter surrounding the concave groove of the suspension is provided on the fixing member, and an engaging portion folded back from a bent portion of an opposing edge portion of an adjacent face plate single member, that is, a roofing roof plate is formed into the concave portion of the suspension. Support it at the bottom of the groove,
The side plate portion of the pressing member is applied to these locking portions, and the pressing member is fastened together with the cover holding member to the recessed groove with a screw that is provided upright in the recessed groove, and the side plate portion is recessed into the recessed portion. It has been proposed that the joint cover is pressed and fixed to the bottom of the roof plate, and the joint cover is elastically held between the bent portions of the adjacent roof plates with the protrusion of the joint cover engaged with the protrusion of the cover holding member.

This product has a cross section of i. This is because a single face plate member such as a roofing roof plate has bent parts bent from both side edges of the face plate part and locking parts folded back from this bent part. Even if the single face plate member has a simple shape and is made of a hard material, has a large thickness, or both of them, it can be easily formed into a desired shape.

ii. By tightening a screw such as a bolt fixed to the bottom of the groove provided in the support portion of the suspension with a screw such as a nut that is screw-fitted to the screw, the side plate portion of the pressing member is engaged with the face plate single member. The side plate portion of the pressing member is used to press the locking portion against the bottom of the groove with a large pressing force to strongly clamp the suspension and the pressing member. This can be done without using deformation, and the face plate single member can be securely and firmly fixed to the suspension.

(Problems to be Solved by the Invention) The invention previously proposed by the inventor of the present application has a mode in which the joint gap between the bent portions is closed by a joint cover and is rain-closed.

However, since there is a single rain-fed structure with a bent portion and a joint cover, and the rain-fed structure is a superposition structure of metal plate members, the warp of the plate member and the product of the plate member Depending on the precision, a gap may remain between the plate members, and it cannot be said that the structure is a sufficient rain end.

In this respect, it may be possible to extend the overlapping range of the plate members (for example, see Japanese Patent Laid-Open No. 2-136460) to make rain sufficiency sufficient, but due to the reasons described above, it is not possible to expect sufficient rain spill. .

Therefore, the inventor has found that the joint between the bent portion 50 and the joint cover 51 is
52 is a silicone-based or butyl-based elastic sealing material 53
I covered and experimented. (See FIG. 4) As a result, the sealing ability of the seam was impaired and the waterproof property was deteriorated, so that it was impossible to achieve the reinforcement of the rain finish by the sealing material.

The reason for this is that it was confirmed that the energy of displacement due to roof expansion and contraction (due to temperature difference) and wind pressure concentrates stress on the sealing material of the seam, and as a result, the sealing ability of the seam by the sealing material is impaired.

The inventor continued the research for avoiding the stress concentration on the sealing material, based on the fact that the expansion and contraction of the roof and the displacement due to wind pressure cannot be avoided, and the sealing material is effective for strengthening the waterproof property. As a result, it has been found that, when the sealing material is sealed with a casing joint, the stress concentration does not occur in the sealing material in the casing joint, and the present invention has been completed.

That is, the present invention solves the above-mentioned problems, and by sealing the casing joint, it is possible to obtain an excellent rain-fighting ability with perfect waterproofness, and moreover, a surface of a building with good workability. The purpose is to provide a structure.
