Description

  The present invention relates to an expansion joint that is installed in a building gap of a building.

The sliding of adjacent housings includes sliding in the horizontal direction including the width direction (X direction) and longitudinal direction (Y direction) of the housing gap, and further sliding in the depth direction (Z direction) of the gap. There is. Along with such sliding, the members installed across the adjacent housings are inevitable to collide, but in order to avoid this, for example, in the ceiling expansion joint, one end of the ceiling portion of the gap portion is It is connected to the ceiling part on the side of one chassis via a pivot, and the tip part is extended to the other chassis side to form a superposed part that can slide horizontally, and the tip side is shifted upward to the other ceiling, that is, the back side. The possible configuration is widely adopted. It is like the following patent document.
JP 2003-176596 A

However, in the conventional fixed structure with one side support, the load on the ceiling part of the frame gap is applied to one end part, so the drooping phenomenon on the front end side is likely to occur, and the larger disadvantage as in the case of wide gap construction compared to narrow gap became. On the other hand, this structure has a problem that the ceiling part can rotate upward due to the one-sided support structure, and a wide frame gap and ceiling space where these support members can move without colliding are required. In addition, there are many buildings in which such a design is difficult to take, and there is a problem that the places where construction is possible are limited.
The present invention has been found to solve the above-mentioned problems, and has been made to solve these problems.The ceiling part is folded in two so that the load on the ceiling part of the frame gap is distributed on both sides, and the rotating structure part is placed on this upper part. The expansion joint that is compact and can be installed even in a narrow ceiling space is provided, and at the same time, the expansion joint can be used as a wall expansion joint.

  In order to solve the above-described problems, the present invention provides a cover portion (for example, a ceiling portion) that covers the housing gap portion as left and right cover portions that are parallel and rotate upright with respect to the longitudinal direction of the gap. The left and right support members are preferably fixed to the back side, preferably in the gap width direction, and the left and right support members are connected to each other by a rotation support arm so that they can be rotationally displaced from each other, and one base end is connected to one housing side. It is pivotally attached to the cover fixing material, and the base end of the connecting member extending in the gap width direction is rotatably attached to the opposite part of the cover fixing material on the other housing side, and the connecting member is supported left and right. A structure in which at least the other support material of the material is slidably fitted in the gap width direction, and more preferably, the one support material is slidable in the gap width direction and detachably moved in the gap depth direction. Have expand Characterized in that without the down joint.

The rotation support arm is preferably formed with a stopper portion that prevents rotation in the front direction while the left and right cover portions are flatly supported, and further includes a pair of two casings curved on the back side, Both ends of one housing are pivotally attached to a portion closer to the base end of one support member and the one support member closer to the one support member, and both ends of the other housing are connected to the distal end portion of one support member. The joint is pivotally attached to the side part and the part near the other end of the other support member, and the intermediate parts of both housings are pivotably attached to each other. It is preferable that the portion is formed.
In any of the above, one of the pivoting member pivotally attached to the base end portion of the support member of the cover portion and the pivoting member pivotally attached to the base end portion of the connecting member fitted to the support member, preferably both, It is preferable to attach to the cover fixing material on the housing side so as to be slidable in the longitudinal direction of the gap.

Further, a rising surface portion is formed on the cover fixing material on which a member in which the base end portion of one of the left and right support members and the base end portion of the connecting member are rotatably attached is formed, and a cover is formed on the rising surface portion. An angle-shaped fixing member that supports the base support material can be configured to be joined and fixed selectively in the forward and reverse directions.
Furthermore, it can be set as the structure which added the structure part which can displace the approach force of a cover surface direction to a surface cross rotation direction.

According to the above configuration, since the cover part (for example, the ceiling part) covering the frame gap part has a double-folded structure of the left and right cover parts that rotate upright and has a double-sided support structure, the load can be supported on both sides and is strong. A stable cover structure that does not require dripping does not occur when a cover base is not required and is horizontal. In addition, since the support structure fits within the height (depth) and the range of the two-fold structure, it is not necessary to provide a wide clearance between the housing and the back of the cover, and can be applied to almost all construction sites.
Movement in the gap width direction can be absorbed by sliding the support material and the connecting member, and by rotating the support material twice and accompanying rotation of the connecting member to the back side. The cover fixing material can be absorbed by having a slide connection configuration, and any combination of these can absorb sliding in any flat direction. The movement in the depth direction of the gap can be absorbed by the pivotal rotation of the base end portions of the connecting member and the support member, and sliding in all directions is possible by combining these.
