JPS6013933Y2 - Fixing device between inner wall board and ceiling edge - Google Patents

Description

[Detailed description of the invention] This invention relates to a fixing device for fixing the inner wall plate and the ceiling edge when the inner wall plate and the ceiling plate are further installed inside the outer wall plate in a prefabricated building made of thin steel plates. The purpose of this is to develop a simple lining member fixing device that reduces the number of fixing members, thereby increasing the efficiency of assembly work.

If the embodiment of the present invention is explained with reference to the drawings, 1 is a corner support;
Reference numeral 2 denotes an intermediate post, and numeral 3 indicates an inner wall plate, and the inner wall plate is stretched along the inner side of the corner post and the intermediate post to which the outer wall plate 14 is fixed, with a gap between them and the outer wall plate. Secure with screws.

Reference numeral 4 is the edge around the ceiling, and a vertical piece of a small vertical piece of the bent piece is welded to the lower side of the inside of the bent piece of the cross section, and a downwardly protruding piece 6 is extended downward from the bottom piece of the open groove 5. It is a rim material whose overall shape has a single-shaped cross section, and the opening grooves 5 are horizontally directed inward along the upper edge of the inner surface of the inner wall plate and are circumferentially provided by fixing means to be described later.

Reference numeral 7 denotes a ceiling plate whose peripheral edge 8 is inserted into the opening groove 5 of the surrounding edge and stretched.

Reference numeral 9 is a corner plate, which is formed into an H-shaped cross section, and is abutted at right angles on the inside of the corner support and is adjacent to the circular wall plate. The protruding piece is held down by its three upper ends and brought into contact with the inner corner surfaces of both inner wall plates, and a triangular prism-shaped corner washer 10 is placed on the inner side of the protruding piece, and is screwed onto the inner end of the corner post with a bolt 11, so that the inner wall plate and The downward projecting piece of the surrounding edge is held between the corner ends and fixed by pressing toward the corner support.

Reference numeral 12 denotes an intermediate part support, which is formed to have a flat trapezoidal cross section, and holds down with its upper end the downward protruding piece of the surrounding edge which is brought into contact with the inner surface upper edge of the inner wall plate which is brought into contact with the inner surface of the intermediate support. In addition, a bolt 13 is screwed onto the inner end of the intermediate support from the inside, and the projecting piece is held between the inner wall and the upper end of the intermediate part and is pressed and fixed toward the intermediate support.

In this way, the inner wall board and the ceiling board are stretched across the four peripheral walls by the above-mentioned fixing means at the inner wall corners and the intermediate part.

The present invention has the above-mentioned structure, and since the downward protruding piece is provided below the opening groove of the surrounding edge, this protruding piece is held between the inner wall surface by the respective parts at the corner and the middle part, and the bolt It is possible to press and fix the inner wall plate and the surrounding edge to the column by screwing them together, and the inner wall plate and the surrounding edge can be fixed at the same time by one means without providing separate means for fixing the inner wall plate and the surrounding edge, so the number of members can be saved. This makes assembly more efficient, and by screwing bolts into each support from the inside, a simple fixing device can be obtained that can fix the same circular member at the same time, which is beneficial in terms of manufacturing and construction.
