Description

TECHNICAL FIELD The present invention relates to an expansion joint for covering a gap in a building, and more particularly to a drainage drain for an expansion joint constructed between gap structures.

[Prior Art] Since a structure is constantly distorted due to temperature changes, uneven settlement, and earthquakes, etc., a gap structure is constructed between the skeletons as a means to prevent destruction of the structure due to the distortion.
Various expansion joints are used as a structure for covering this gap.

In the structure of this type of expansion joint, conventionally, only the outermost part of the gap structure is covered so as not to hinder the expansion and contraction of the gap, and the other uses of the gap structure itself are not considered, and a large space is not used. It was left as it was, and the use of the gap structure was demanded.

[Problems to be Solved by the Invention] The present invention has been made in view of the above demands, and is intended to utilize not only a gap structure of a building as a strain absorbing structure but also as a drainage facility. The purpose of the present invention is to provide a drainage drain for expansion joints.

[Means for Solving the Problems] The drainage drain for expansion joints according to the present invention is installed in the gap adjacent to the expansion joint covering the wall surface of the strain absorbing gap formed between the two structures of the building. The purpose of the present invention is to form a hollow pipe having an appropriate cross-sectional shape, which is made of a flexible material such as polychloroprene or chloroprene polymer rubber, and integrally form a mounting structure extending over the entire length.

Further, it is preferable that the mounting structure is fitted to a fitting structure formed on at least one frame base of the expansion joint, and the drain for drainage is suspended in the gap. The hollow part of the drainage for drainage may be formed integrally with a water-stop trough that is suspended between frame bases of expansion joints that are fixedly fixed to both frames of the building. Further, the drain for drainage may be configured by a plurality of independent drain groups.

[Operation] According to the above configuration, a drain for drainage having a pipe-shaped body made of a flexible material is arranged in a gap between the skeletons covered by the expansion joint, and polychloroprene, chloroprene polymer rubber, or the like is used. It is deformed by elasticity and does not interfere with the operation of the expansion joint. Moreover, not only does the hollow pipe-shaped main body not be damaged even if it is crushed due to the narrow displacement of the gap, but the elasticity also causes the hollow pipe to expand and return to withstand reuse, making the gap structure of the building not only a strain absorbing structure. It can also be used as a drainage facility.

[Examples] Examples of drainage drains for expansion joints according to the present invention will be described below with reference to the drawings.
