Abstract

PURPOSE:To prevent the occurrence of a risk of breakage and dropping and to provide safe and reliable preventing structure by a method wherein back fasteners are mounted to two ends of a fixing plate inserted in the hollow part of a hollow panel building material, and coupling is effected by means of a press plate through which the fixing plates are intercoupled. CONSTITUTION:A fragment protective sheet 7 is laminated to the back of a hollow ceramic panel 1, and a hole for mounting a back fastener 20 and a hole for mounting a press plate 10 are formed in positions on a panel 1. A fixing plate 3 with a square nut 4 is inserted in a hollow hole 2 of the hollow ceramic panel 1, the press plate 10 is mounted through adjustment of the screw of the square nut 4, end is coupled to the fixing plate 3. This constitution simplifies positioning, improves workability, prevents separation of a broken piece even during an excessive impact, and prevents the occurrence of dropping.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a falling-off prevention structure for hollow panel building materials that prevents the hollow panel building materials from scattering and falling off when they are damaged.

[Prior Art 1-41 For exterior building materials such as crystallized glass and ceramic building materials, a shatterproof adhesive sheet has conventionally been attached to the back side of the building material to prevent it from scattering when damaged.

[Problem to be solved by the invention 1 With hollow panel building materials, the adhesive sheet for preventing scattering as described above and the back fastener that attaches the hollow panel building material to the base have a cut edge. Adhesive sheets are effective against damage caused by small impacts, but if there is excessive impact caused by flying objects or the like, there is a risk that the back fastener attachment part will be damaged and the hollow panel building material itself will fall. As described above, the present invention eliminates the risk of major damage and falling due to earthquakes and shocks, which is a problem when applying the widely used adhesive sheet for preventing scattering to hollow panel building materials, and is safe. The purpose is to provide a reliable structure to prevent hollow panel building materials from falling off. [Means for Solving the Problems 1] The present invention has a mounting part that is inserted into a hollow hole of a hollow panel building material, penetrates the wall surface at both ends thereof, and fixes a back fastener, and a large number of nuts are fixed in the middle part. A hollow panel building material, characterized in that it is formed by combining a fixing plate made of a thin elongated plate, and a holding plate that is attached to the outer surface of the hollow panel building material and connected to a plurality of fixing plates by bolts that are screwed into the nuts. It has a structure that prevents it from falling off. [Operation 1] The fixing plate of the present invention inserted into the hollow part of the hollow panel building material has back fasteners attached to both ends thereof, and is joined by a presser plate that connects the fixing plate. Therefore, since the back fastener, fixing plate, and presser plate are all connected and integrated, even if the hollow panel building material is damaged by excessive impact, the entire panel will not fall off.

Attach the shatterproof sheet to the back side in advance.
If this anti-scattering sheet is sandwiched between a fixing plate and a holding plate in a sandwich structure, the fixing plate will be connected to the back fastener, and the back fastener will be connected to the frame mounting bracket, strengthening the integration. Therefore, even if the hollow panel building material is damaged, it will not fall. [Example] Figure 1 shows a three-sided view of an example of the present invention. The hollow ceramic panel 1 has a length of 1000 mm, a width of 450 mm, and a thickness of 2.
There are 14 hollow holes 2 with a thickness of 6 mm, and the wall thickness of each part is approximately 6 mm. A shatterproof sheet 7 is pasted on the back side of this hollow ceramic panel 1. Holes of 10 mm diameter for attaching the back fastener 20 and the holding plate IO are drilled at predetermined positions in the hollow ceramic panel l.

Insert the fixing plate 3 with the square nut 4 as shown in Fig. 2 into the hollow hole 2 of the hollow ceramic panel l, and
Align the screw of square nut 4 with the mφ hole. Attach the holding plate 10 shown in Figure 3 to the specified position and connect it to the fixing plate to complete the work. The bolt holes in the holding plate were long holes l1, so the work was easy and smooth. This structure prevents the hollow panel building materials from falling off.

[Effects of the Invention J] The drop-off prevention structure for the hollow panel building material of the present invention has a square nut welded to the fixing plate at a predetermined position, so positioning is extremely simple and workability is good. In addition, the back fastener attachment parts are connected by a fixing plate, and the fixing plates are connected by a presser plate on the outside, so even if vertical or horizontal cracks occur due to excessive impact, the pieces of the hollow panel building material will not separate. Furthermore, since the frame mounting bracket and the fixing plate are connected via a back fastener, there is no need to worry about them falling off.
