Description

[Detailed description of the invention]

[INDUSTRIAL APPLICATION FIELD 1] The present invention relates to a mounting hardware used when extruded hollow panel building materials manufactured by extrusion molding are vertically attached to a building frame, wall surface, or the like.

[Prior art 1] Conventionally, the structure shown in Fig. 5 has been used for the construction of artificial stone, crystallized glass, etc., which is generally used for the exterior of buildings, etc.
The mounting fittings are composed of an angle 23 and a connecting fitting 24 as shown in FIG. The conventional stone mounting structure is as follows. As shown in Figures 5 and 6, the concrete wall 2 of the frame
An angle 23 is attached to the anchor bolt 22 attached to 1, and a connecting fitting 24 is attached to the angle 23. A hole 27 into which the dowel pin 26 is inserted is opened in the exterior material 25 such as stone, and the dowel pin hole 28 of the connection fitting 24 and the exterior material 25 are opened.
Pass the dowel pin 26 through the dowel hole 27 and press down the exterior material 25 from top to bottom to attach it. Finished surface (outer surface of exterior material)
In order to adjust the ingress and egress of the connecting fitting 24, the bolt through hole 29 and dowel pin hole 28 are each loose holes, so that the joint width and the ingress and egress of the exterior material surface can be adjusted. Further, the dowel pin 26 is fixed by injecting epoxy resin, quick hardening cement, etc. into the dowel hole 27 on the exterior material side. In most cases, each piece of exterior material is attached to the building frame in two places, one on the top and one on the top, using these mounting brackets. When applied to the vertical installation of extruded hollow panel building materials with the same structure as this exterior mounting structure using stone 2. Exterior hollow panels and ceramic hollow panels, etc. must have hollow holes and be lightweight. Due to the thin walls, it is not possible to provide dowel holes in the vertical end faces. Furthermore, when extruded hollow panel building materials are subjected to vibrations or shocks such as earthquakes, there is a risk that cracks may occur in the hollow panels. In addition, in order to fix dowel pins in stone, etc., epoxy resin or quick-hardening cement is injected into the dowel holes, but this cannot be done when vertically extending hollow panel building materials. [Problem to be Solved by the Invention J] When using the generally widely used metal fittings for attaching stone to the frame as described in F-F for the construction of vertically extending extruded hollow panel building materials 2 Extruded hollow panel building materials Since it has a hollow hole and is thin, it is not possible to fix a dowel pin. The object of the present invention is to provide a 14-piece dowel pin receptacle for extruded hollow panel building materials that eliminates the above-mentioned problems. 1. Means for Solving the Problems The present invention is a dowel pin mounting hardware used when vertically extending extruded hollow panel building materials, and is comprised of the following (a) and (b). (a) U-shaped leaf spring 9 that is inserted into the hollow hole of the extruded hollow panel building material and has ears that elastically adhere to the inner wall of the hollow hole and lock onto the end face of the panel building material (b) U7 of the 11-shape diagonal spring
A block that is housed inside and connected to the U-shaped bottom at the U-shaped bottom, and includes a mounting bracket having a dowel pin insertion hole and a panel mounting bolt hole drilled on the side surface. [Function] Since the four-piece hardware of the present invention is elastically fixed within the hollow hole of the extruded hollow panel building material, the force transmitted from the dowel pin to the hollow panel is dispersed. Therefore. Damage to the area around the dowel pin of the hollow panel building material is prevented. To fix the dowel pin, the amount of conventionally used epoxy resin or quick-hardening cement is almost the same as when using stone. During construction, it is sufficient to simply insert the mounting hardware of the present invention into the hollow hole of the hollow panel building material, and no other difficult operations are required and no specific craftsman is required. [Example] Figures 1 to 3 show examples of the dowel pin mounting fitting of the present invention. FIG. 1 is an exploded view of the moe attached to the extruded hollow panel building material l. Fig. 2 shows an example of the dowel pin mounting hardware, Fig. 3 shows a diagram of the dowel pin mounting hardware, and Fig. 4 shows an overall view of the panel mounting procedure. The extruded hollow panel building material l is a hollow ceramic panel, with a length of 2000 nm, a width of 300 mm, and a thickness of 26 mm.
There are 9 hollow holes in rnrn, and the wall thickness of each part is approximately 6rnr.
It is about n. Holes 20 for screwing dowel pin mounting hardware are opened in the hollow panel building material l at corresponding positions. A falling-off prevention fitting 31 is inserted into the hollow hole 2 of the hollow panel building material 1 at a position where a metal fitting is to be attached. This drop-off prevention metal fitting 31 is a thin piece with a width that fits loosely into the hollow hole 2, and the middle part thereof is bent so as to be pleated so as to contact the wall of the hollow hole. , its total length is approximately equal to the height of the hollow panel building material, and elongated holes 32 are provided near both ends so that the set screws of the dowel pin mounting hardware pass through these elongated holes. Even if the hollow panel 1 were to be damaged due to a collision or the like, the drop-off prevention fittings 31 are connected to the upper and lower dowel pin mounting fittings, so that the hollow panel 1 is prevented from falling off. Next, the dowel pin fixing metal 1 consisting of the U-shaped leaf spring 11 and the block 16 is inserted into the hollow hole 2 in the direction of the arrow 18. At this time, the leaf spring it elastically comes into close contact with the side wall of the hollow hole 2, and its both ears 12 are engaged with the edges of the hollow hole 2 on the end surface of the hollow panel l. A set screw 19 is screwed into the threaded hole 17 of the dowel pin attachment through the hole 20 and fixed. Take dowel pins (1) at two places on the top and bottom of the extruded hollow panel building material, drive the dowel pins 14 into the holes 15, and attach the frame mounting bracket to the dowel pins 14. That is, the dowel pin 14 is inserted into the dowel pin insertion hole, and the dowel pin 14 is fixed with an adhesive such as evogishi resin. This dowel pin 14
At the same time, the mounting brackets 124 are attached to the frame and the vertically adjacent hollow panels are joined to each other. By using the dowel pin attachment hardware of the present invention, it is extremely easy to attach an extruded hollow panel building material to a building frame. [Effects of the Invention J] According to the present invention, extruded hollow panels can be easily attached to the framework of U-buildings, and damage to the attachment portion due to vibrations, impacts, and other loads can be completely prevented.
