Description

本発明は、躯体間隙を被覆し、躯体間の変動のズレを吸収することができるエキスパンションジョイントに関する。 The present invention relates to an expansion joint that covers a gap between the frames and can absorb a shift in fluctuations between the frames.

従来のエキスパンションジョイントとしては、躯体間隙を被覆するカバー材の一端側を一方の躯体に載せ、他端側を少なくとも躯体間隙奥行き方向に可動に他方の躯体に連結し、傾斜面部を有する支持部材を、カバー材の裏面に備えたものがあり、これは、例えば、支持部材が一方の躯体に乗り上げたり、カバー材の先端が躯体上を摺動したりして躯体間の変動を吸収することができるものである（下記特許文献１参照）。 As a conventional expansion joint, a support member having an inclined surface portion is formed by placing one end side of a cover material covering the housing gap on one housing, connecting the other end to at least the other housing movably in the depth direction of the housing gap. In some cases, the back surface of the cover material is provided. For example, the support member rides on one housing, or the tip of the cover material slides on the housing to absorb the variation between the housings. (See Patent Document 1 below).

上記のようなエキスパンションジョイントは、大きな変動量を吸収するためには、躯体間隙幅を広くする必要があり、それに合わせて、カバー材も大型化しなければならない。大型化したカバー材は重くなるため、運搬がし難く、施工時の安全性などに問題が生じていた。 In order to absorb a large amount of fluctuation, the expansion joint as described above needs to widen the frame gap width, and the cover material must be enlarged accordingly. Since the large cover material becomes heavy, it is difficult to transport, and there has been a problem in safety during construction.

そこで、本発明の目的は、大型化しても軽量であるエキスパンションジョイントを提供することにある。 Therefore, an object of the present invention is to provide an expansion joint that is lightweight even if it is enlarged.

本発明のエキスパンションジョイントは、躯体間隙をカバー材で被覆するエキスパンションジョイントにおいて、カバー材を、略矩形状のハニカムコアと、その周縁に設けた枠体とを備えた構成としたことを特徴とする。 The expansion joint according to the present invention is characterized in that, in the expansion joint that covers the gap between the casings with a cover material, the cover material is configured to include a substantially rectangular honeycomb core and a frame body provided on the periphery thereof. .

本発明は、ハニカムコアをカバー材として用いているので、大型化しても軽量であり、運搬がし易く、施工も安全に行なうことができる。 In the present invention, since the honeycomb core is used as a cover material, it is lightweight even if it is increased in size, is easy to carry, and can be safely constructed.

上記エキスパンションジョイントは、上記枠材の表面の内方側を段状に凹ませ、少なくとも表面材が納まる表面材納まり部を設けてある構成とすることができる。 The expansion joint may have a configuration in which the inner side of the surface of the frame member is recessed in a step shape and a surface material storage portion in which at least the surface material is stored is provided.

このような構成とすることにより、表面材のみ又は表面材及び仕上材を表面材納まり部に納めれば、カバー材の表面を形成することができ、表面材、仕上材の取り付けが容易になる。また、表面材納まり部の深さは、表面材の厚さ又は表面材及び仕上材の合計厚さと略同じに形成しておけば、カバー材の表面に段差がなくなり、平滑な表面にすることができる。 By adopting such a configuration, the surface of the cover material can be formed if only the surface material or the surface material and the finishing material are stored in the surface material receiving portion, and the attachment of the surface material and the finishing material becomes easy. . In addition, if the depth of the surface material receiving portion is formed to be approximately the same as the thickness of the surface material or the total thickness of the surface material and the finishing material, the surface of the cover material will have no step and the surface will be smooth. Can do.

上記エキスパンションジョイントは、上記枠材の裏面の内方側を段状に凹ませて、裏面材が納まる裏面材納まり部を設けてある構成とすることができる。 The expansion joint may be configured such that the inner side of the rear surface of the frame material is recessed in a step shape and a back surface material receiving portion in which the back surface material is stored is provided.

このような構成とすることにより、裏面材を裏面材納まり部に納めれば、カバー材の裏面を形成することができ、裏面材の取り付けが容易になる。また、裏面材納まり部の深さと裏面材の厚さとを略同じに形成しておけば、カバー材の裏面に段差がなくなり、平滑な裏面にすることができる。 By setting it as such a structure, if a back material is stored in a back material storage part, the back surface of a cover material can be formed and attachment of a back material will become easy. Further, if the depth of the back material receiving portion and the thickness of the back material are formed substantially the same, there is no step on the back surface of the cover material, and a smooth back surface can be obtained.
