DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention provides a building material having uneven portions on a surface or an outer wall material provided on the surface with a gap therebetween, and a cover material covering the above-mentioned gap on the building body. The present invention relates to an expansion joint constructed by installing.

(Prior Art and Its Problems) Generally, the surface of a building body having an uneven portion in a parallel shape or a grid shape, which is composed of aggregates combined in a parallel shape or a grid shape, has a corrugated or uneven outer wall material on the surface. When covering or when there is an uneven portion on the surface of the core wall of the building structure, when two such building structures are provided with a gap and an expansion joint is applied, the aggregate, the body surface or the outer wall material is corrugated. Alternatively, since it is formed in a concavo-convex shape, it is difficult to treat the side edge portion and the surface of the building frame or the cover material in a hermetically sealed manner. This is because the gap between the corrugated surface or the surface of the uneven portion and the cover material of the expansion joint is changed, and therefore, conventionally, the gap between the outer wall material or the trough portion of the building frame surface and the cover material is changed. There was a drawback that it was easy to create a gap.

(Technical problem of the invention) The present invention solves the above-mentioned drawbacks, and in particular, in an expansion joint intended for a building body in which unevenness is formed on a surface or an outer wall material covering the surface, the building body surface or the outer wall material and the cover are covered. It is a technical subject to provide an expansion joint which can satisfactorily deal with fitting with a material.

(Means for Solving the Problem) In order to solve the above-mentioned problems, the expansion joint according to the present invention is provided with a building structure in which uneven portions are provided on a surface or an outer wall material provided on the surface with a gap, and the above-mentioned building structure is provided. An expansion in which a flat blind portion is provided along the gap-side end portion, a support member is provided on the blind portion, and a cover material that covers the gap is supported by the support member through an engaging member. In the joint, the side end of the cover material is brought into contact with the blindfold portion or the supporting member, while a step portion is formed at the side end portion of the blindfold portion, and the stepped portion has an uneven portion on the surface of the building frame. Alternatively, an edge portion of the outer wall material covering the surface is arranged to seal between the blindfold portion and the outer wall material or the building frame.

Further, the support member may be integrally provided on the blindfold portion.

(Advantages and effects of the invention) According to the above configuration, the concavo-convex portion of the surface of the building frame or the edge portion of the outer wall material that covers the surface is arranged on the stepped portion of the blindfold portion, and the blindfold portion and the outer wall material or the building body. By sealing the space between the surface of the building body and the outer wall material surface that oscillates various surface shapes, it is possible to satisfactorily treat the space between the blindfold portion and the cover material to obtain an expansion joint having high airtightness.

In addition, by integrally providing a support member for the cover material in the blindfold portion, the number of parts and the construction labor can be reduced.

Airtight materials 15 are fitted on the back surfaces of both side ends of the cover material 5 and abut on the surface of the blindfold portion 7.

Next, the end of the outer wall member 2 that covers the surface of the building frame 3 on the side of the gap S is arranged on the step 7a of the blindfold 7 of the blindfold member 6. The space between the end of the outer wall material 2 and the blindfold 7 is sealed by a sealing material 16 such as a sealing material or a soft synthetic resin.

With the above configuration, the end of the cover material 5 is in contact with the blindfold portion 7 without being influenced by the shape of the outer wall material 2 or the surface of the building body 3 or a member having a recess via the airtight material 15, so that the airtightness is ensured. And the end of the outer wall material 2 is a stepped portion of the blind member 6.
It is engaged with 7a. Therefore, the space between the outer wall material 2 or the surface of the building body 3 having various shapes and recesses and the cover material 5 can be favorably treated, and an expansion joint having good airtightness can be obtained.

The closer the height of the step 7a is to the interval between the peaks and valleys of the outer wall material 2, the more it is not affected by the shape of the outer wall material 2 and the like, so that the end treatment can be easily performed.

Further, the aggregate 1 can be processed in the same manner even if it is assembled in a lattice shape. The support of the cover material 5 is not limited to that shown in the figure. For example, a bolt may be inserted from the center of the cover member 5 and the tip of the bolt may be locked in the center of the engaging member 12, or the engaging member as shown in FIG.
The structure may be such that 12 is fixed to the support member 17 and the cover member 5 is supported by the support member 8.

Furthermore, the arrangement mode of the blind members 6 and the end portions of the outer wall member 2 is not limited to the illustrated example. For example, as shown in FIGS. 1 and 2, the claw portion 6c may be engaged with the blindfold member 6 provided on the gap S side of the end portion of the C-shaped aggregate 1, and FIG. ), The engaging groove 18 is formed in the step portion 7a of the blindfold portion 7 of the blindfold member 6, and the sealing material 16 and the end portions of the outer wall material 2 are engaged with the engaging groove 18. Alternatively, the airtight material 15 may be fitted in the engagement groove 18 as shown in FIG.

Next, FIG. 4 is an example of the expansion joint provided in the case of an entering corner configuration in which one building frame 3 and the other building frame 4 have a gap S and form a right angle, and the gap between the building frames is shown. The blind member 6 is provided at the end of the aggregate 1 on the S side.
