Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a movable device for a decorative cover in an architectural expansion joint.
[0002]
An expansion joint for construction is a dividing line provided to divide the transmission of stress generated by fluctuation factors such as external force applied to a building, and prevents a clash between left and right buildings built adjacent to each other. It is a joint member that closes the clearance (gap) provided by the wall with a decorative cover that can move following the shaking movement of the building, and connects the left and right buildings so that they can be used together.
[Prior art]
[0003]
The decorative cover material attached to the conventional expansion joint part is provided to support the decorative cover because the assumed change in clearance due to temporary deformation such as an earthquake or permanent deformation such as non-uniform subsidence is relatively small. In many cases, the cover is fitted and mounted between decorative cover support materials (decorative edge materials) at both ends. Both ends of the conventional decorative cover have a configuration in which the prospective extension portion is stored in the decorative cover support material in an overlapping manner, and there is a clearance gap in the decorative cover support material so as to cope with shrinkage. And the change in the clearance due to an earthquake or the like is followed between the decorative cover support members.
[0004]
In recent years, however, due to the increase in size and height of buildings, the clearance (gap) between buildings has increased from about 50 mm to 300 mm, but has increased from 400 mm to 1000 mm. Many expansion joints that can follow permanent deformation such as these have come to be used.
[0005]
An expansion joint with a large clearance covers the clearance with a decorative cover material made of metal such as stainless steel or aluminum, so naturally the weight of the decorative cover material becomes heavy, and the heavy weight decorative cover material There has been a demand for a safety structure that is firmly installed and a movable mechanism that can smoothly move the decorative cover to follow the shaking against temporary deformation such as an earthquake and that does not damage the decorative cover or the building.
[Problems to be solved by the invention]
[0006]
In the expansion joint that can cope with the increase in size and height of buildings with a clearance of 400 mm to 1000 mm, the present invention smoothly moves the decorative cover, which becomes heavy, following the temporary deformation such as an earthquake. An object of the present invention is to provide a movable device of a decorative cover in an expansion joint that is capable of following and is firmly supported by the heavy-weight decorative cover material and has high functionality and safety.
[0007]
[Means for solving the problems]
In order to achieve the above-mentioned object, the present invention is to mount a plurality of telescopic slide rails having an outer rail and an inner rail at an arbitrary pitch in a clearance C set between buildings A and B facing each other. One end of the outer rail of the slide rail is fixed to, for example, a hinge arm of a hinge mechanism fixed to an edge material on the building A side, and the other end of the slide rail is attached to the edge of the building B or the edge. It is configured to always engage with the upper part of the extended receiving material, and a plurality of decorative covers covering the clearance C are fixed to one side of the plurality of slide rails arranged at an arbitrary pitch with screws or the like. The decorative cover slides smoothly through the slide rail on the edge of the building B or the receiving material provided to extend from the edge, and sudden temporary deformation due to an earthquake or the like Follow-up was constructed as can be.
[0008]
Moreover, the movable device of the decorative cover in the expansion joint of the present invention can be widely implemented as an expansion joint, such as an inner wall-inner wall, an inner wall corner, an outer wall-outer wall, an outer wall corner, a floor-floor, and a floor corner. To provide a robust decorative cover movable device that is robust and does not come off because a heavy decorative cover is fixed and attached to a plurality of slide rails mounted between clearances C with screws or the like.
