Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for attaching a hollow molded plate-like body having a plurality of parallel longitudinal through holes.

Hollow-molded plate-like bodies with a large number of parallel through holes are manufactured by combining wooden materials, injection molding of plastic materials, extrusion molding, and other methods. Because molded plate-like bodies can be obtained freely, this method is most commonly used for building interior and exterior wall materials, partition materials, etc. Therefore, the following description focuses on the method of attaching this extruded plate to the support of the construction.

In general, extrusion molded plate-like bodies are manufactured by extrusion molding for the purpose of reducing the weight of the hollow-molded plate-like body 1, reducing costs, making it easier to extrude, and improving heat insulation properties, as shown in Fig. 1. A large number of rectangular through holes 2 are provided in parallel, passing through the hollow molded plate-like body 1 in the vertical direction and opening in a line in a plane perpendicular to the vertical direction. When attaching this hollow molded plate-like body 1 to the support 3 of a structure,
Conventionally, screws or nails 4 were passed perpendicularly to the flat surface of the plate-like body 1 from outside to push it, or the plate-like body 1 was pulled onto the plate-like body 1 from the support 3 side of the structure using the screws 4'. In these cases, reinforcement was also attempted by increasing the thickness of one of the plate-shaped bodies.

However, when screwing or nailing a hollow molded plate-like body as described above, it is done through the through-hole of the hollow-molded plate-like body, but in that case, the attachment stress is concentrated on a part of the wall of the through-hole 2. However, since it is easy to break, it is necessary to make the mounting strength of each one relatively weak, and there are disadvantages such as an increase in the number of screws and nails used. Furthermore, when the surface thickness is increased as described above, there is a problem in that the manufacturing process is complicated.

In view of the above-mentioned circumstances, the present invention has been devised to provide a method for attaching a hollow-molded plate-like body to a support such as a structure, which can be firmly attached to a support such as a structure without increasing the number of mounting screws or increasing the surface thickness of the plate-like body. The purpose of this invention is to fix a hollow-molded plate-like body having a plurality of parallel through-holes extending in the vertical direction to a support body, and the above-mentioned through-holes of the plate-like body are fixed to a support body. Insert a long receiving metal fitting having a U-shaped cross section into one or more of the through-holes so that its back face faces the support side plate surface of the through-hole, and pass it from the support side through the through-hole plate surface. The method involves fixing the hollow molded plate-like body to the support body using a screw that is screwed into the back surface of the receiving metal fitting.

The method of the present invention will be explained below with reference to the drawings.

FIG. 2 is a perspective view of the receiving metal fitting 11 used in the method for attaching a hollow molded plate-like body according to the present invention. The receiving fitting 11 is formed by bending both edges extending in the length direction of a rectangular metal plate in the circumferential direction, and has a U-shaped cross section consisting of opposing side surfaces 11a, 11a and a back surface 11b. It's summery.

3 and 4 show an example of a method for attaching the hollow molded plate-like body 1 using the above-mentioned receiving fitting 11, and reference numeral 12 in the figure shows a base column which is a support body to which the hollow-molded plate-like body 1 is attached. It is. In the through hole 2 of the portion of the hollow molded plate-like body 1 to be attached to the base column 12, the receiving metal fitting 11 connects the back surface 11b to the through hole 2.
It is inserted toward the side plate surface 2a of the support body. The screw 13 passed through the base pillar 12 passes through the plate surface 2a of the through hole 2 and is screwed into the back surface 11b of the receiving metal fitting, and the hollow molded plate-like body 1 is pressed and fixed by the back surface 11b. are doing.

Further, FIGS. 5 to 7 are diagrams showing another method of attachment, in which the device is not directly attached to the base column 12 but is attached to the base column 12 via a fastening metal fitting 14. The fastener 14 has a shape (short angle shape) in which a rectangular plate is bent at the center in the longitudinal direction, and extends in a direction perpendicular to the bent portion 14b near the center of the flat plate 14a at one end. long hole 1
5 is drilled therein, and a screw hole 16 for attachment to the foundation column 12 is bored in the flat plate 14c at the other end. The fastening metal fitting 14 is arranged on the outer surface of the plate surface 2a of the through hole 2 so that the extending direction of the elongated hole 15 coincides with the extending direction of the through hole 2 through which the receiving metal fitting 11 is inserted. Insert the elongated hole 15 into the plate surface 2.
It is fixed by a screw 13 that is screwed into the back surface portion 11b of the receiving fitting 11 through the hole a. Next, the screw 17 inserted through the screw hole 16 of the fastener 14 fixed to the hollow molded plate-like body 1 is inserted into the base column 12.
The hollow molded plate-like body 1 is fixed to the base column 12 by screwing the hollow molded plate-like body 1 to the base column 12. In the above operation, the screws 13 are loosened, and after fixing the fixing fitting 14 to the foundation column 12 with the screws 17, tighten the screws 13.
5, it is possible to absorb both left and right directions.

In either method, self-drilling is usually used for the screw 13 that is screwed into the receiving metal fitting 11.

Next, the operation of the above mounting method will be explained.

The receiving metal fitting 11 can be mounted directly or by a fixing metal fitting 14 by a screw 13 that is inserted into the through hole 2 with the back surface 11b facing the side plate surface 2a of the support and is screwed into the back surface 11b through the plate surface 2a. It is attached to the foundation pillar 12 via. In this case, the back surface 11b of the receiving metal fitting is pulled by the screw 13, and the plate surface 2a is accordingly pressed against the base column 12 or the surface 14a of one end of the fastening metal fitting. Since both side surfaces 11a, 11a of the back surface portion 11b of the receiving metal fitting are integrally attached, it is difficult to bend, and the tensile force of the receiving metal fitting 11 due to the screw 13 is converted into a pressing force by the surface of the back surface portion 11b on the plate surface 2a. to work. Therefore, the hollow molded plate-like body 1 is reinforced and firmly fixed. Moreover, the above-mentioned receiving metal fittings have opposing surfaces 11a,
Since the legs 11a serve as legs and support the back surface 11b, the back surface 11b does not separate from the plate surface 2a even when pushed when screwing the screws 13, and the screws can be easily screwed together.

Note that if the width of the space between both side parts 11a and 11a is slightly widened, the receiving metal fitting 1 inserted into the through hole 2 can be
1 will not fall off when handling the plate-like object, making the installation work easier.

In addition, as shown in FIG. 8, when installing on an irregular base pillar 12 such as around a window 18, etc., cut the hollow molded plate-like body 1 to an appropriate width, and
The receiving fitting 11 is inserted into the through hole 2 at a convenient position for fixing the window edge to the window rim, and can be easily attached with the screw 13.

As described above, the method for attaching the hollow molded plate-like body according to the present invention is as follows: (1) Since the receiving metal fitting has a U-shaped cross section, (a) the receiving metal fitting extends over the entire length of the plate-like body; Since the plate-shaped body is fixed over a long length by the pressing force of the surface of the unbent back surface, the plate-like body is reinforced and firmly fixed.

(b) Since the back side is supported by the side view of the support of the through hole, it is easy to screw in the self-drilling screw.

(c) The receiving metal fitting inserted into the through hole does not fall off and is easy to install.

(2) Since this method is designed to be fastened from the indoor side, (a) the screw head does not protrude outside the exterior wall, so it is superior in terms of waterproofing and aesthetics.

(b) It is economical because it often requires less scaffolding.

(c) Construction can be carried out in cases where the boundary between adjacent buildings is narrow.

(3) Even when it is necessary to use a cut hollow-molded plate-shaped body at an arbitrary position, such as around a window, it is possible to insert the appropriate receiving metal fitting into the through-hole and attach it at the desired position.

It has many advantages such as
