Description

[Detailed description of the invention] (Industrial application field) The present invention is an architectural hollow panel used for the outer walls of buildings, etc., and particularly an extrusion-molded hollow panel made of an inorganic material formed by extrusion. This invention relates to a fixing device for fixing to a substrate.

(Prior art) Conventionally, inorganic materials such as camsium silicate and cement have been used as architectural panels used for exterior wall materials, etc., in order to improve productivity and reduce weight, as well as improve heat insulation and sound insulation properties. Alternatively, it is an extrusion molded panel formed by extrusion molding a material containing an organic substance, and a plurality of hollow holes penetrating the panel body in the long side direction (extrusion longitudinal direction) are formed inside the panel body. It is known to be provided in horizontal rows in the side direction (see, for example, Japanese Utility Model Publication No. 1983-435).

Conventionally, when attaching such a hollow panel for construction to the building frame (substrate), it is done by driving screws or nails from the surface side of the hollow panel. In order to reduce the driving resistance and prevent bending, etc., this was done through a hollow hole in a hollow panel.

(Problem to be solved by the invention) However, when screwing or nailing is performed through a hollow hole in a hollow panel as described above, driving stress is locally concentrated in the flesh on the surface of the hollow hole corresponding to the driving location. and easily damaged. Therefore, it is necessary to adjust the force for driving, and when the number of driving points is increased, there is a problem that the number of screws or nails increases. Furthermore, in the case of normal construction, it was necessary to attach a rim.

The present invention was developed in view of the above, and its purpose is to fix construction hollow panels as described above by using the hollow holes without relying on screws or nails. The object is to be able to be fixed to the base with good properties and good appearance.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a hollow panel for construction is attached to a base by sandwiching the fleshy part of the back side of the hollow hole.

Specifically, the method taken by the present invention is to fix an architectural hollow panel, in which a plurality of hollow holes penetrating in the long side direction are formed in horizontal rows in the short side direction, to the base as a fixing device to the base. a mounting base having a contact flange protruding laterally that abuts the back surface of the short side end of the hollow panel; A clamping piece is fixed to the base by fixing means such as bolts, and clamps the flesh part of the back side of the hollow hole at the end of the short side of the hollow panel with the abutment flange part. .

(Function) With the above configuration, in the case of the ventilation construction method of the present invention, when a hollow architectural panel is attached to a base, the structure is A mounting base is fixed in advance to the main part of the frame with screws or nails, etc., and with the back of the short side end of the hollow panel in contact with the contact flange of this mounting base, the hollow panel is clamped. By fitting and engaging the end of the piece into the hollow hole of the hollow panel and tightening and fixing it to the mounting base with fixing means such as bolts, the short side end of the hollow panel is secured between the clamping piece and the abutting flange. The hollow panel is attached and fixed to the base while sandwiching the flesh part on the back side of the hollow hole in the section.

In this case, the installation of the hollow panel depends on the clamping between the abutment flange of the mounting base fixed to the base and the clamping piece fixed to the mounting base, and it is not possible to install it with conventional screws or nails. There is no risk of damage due to stress concentration due to driving.
Moreover, it can be installed and fixed reliably and easily without requiring any adjustment of force. Furthermore, since the installation of the hollow panel to the substrate is performed only at the short side end of the hollow panel while ensuring the reliability of the installation, the number of installation points can be reduced, and the short side end of the hollow panel It is fixed to the main part of the building frame through the ventilation insulation material of the building corresponding to the part, so there is no need to attach a rim or the like. In addition, in the general construction method, if the above-mentioned clamping piece is fixed to the mounting base with a predetermined distance (corresponding to the thickness of the back side wall of the hollow hole) from its abutting flange, the front side Even if there is no space to install from the back side, it can be installed by inserting the hollow hole back side flesh part at the short side end of the hollow panel between the abutting flange part and the holding piece from the back side. .

A pair of clamping parts 17d, 17d that clamp the back side flesh part of the hollow hole 2 are provided protrudingly, and as shown in FIG. The short side end portion of the hollow panel A is positioned and held by being fitted. The other configurations and construction procedures are similar to those of the above-mentioned horizontal cladding, and it is possible to similarly improve the workability and appearance. In addition, in the case of this vertical installation, the main joint part (the fitting part between the male part 3 and the female part 4) of the horizontally adjacent hollow panels A, A is connected to the studs through the ventilation insulation material C. 6
Alternatively, when the wall is positioned corresponding to the main pillar 5, the support member 15 as described above is used to hold the main joint, thereby further increasing the strength of the wall.

In the case of the general construction method, Figures 17 to 19 show the case of horizontal construction using the general construction method, and Figures 20 to 2
As shown in Figure 2, the case of vertical construction using the general construction method is shown.
The hollow panel A can be constructed by directly attaching the fixing devices B, B' and the supporting members 14 to 17 to the main pillars 5 and studs 6 in the same manner as in the case of horizontally or vertically cladding described above. Further, even if there is no space for construction from the back side, the hollow panel A can be attached from the back side by fitting into the fixing device B and the supporting members 14 to 16.

Further, in the above embodiment, the male part 3 and the female part 4 are provided at the long side end of the hollow panel A, and the real joint is made at the long side end, but a joint structure may also be used. In addition, for vertical installation, etc., a simple butt joint structure may be used.

Furthermore, as architectural hollow panels to which the present invention is applied, in addition to those made by extrusion molding as described above,
Various hollow panels can be used, such as those made by casting or assembled.

(Effect of the invention) As explained above, according to the invention, the hollow panel for construction can be fixed to the base by attaching the flesh part on the back side of the hollow hole at the end of the short side where the hollow hole opens. This is done by clamping the abutment flange of the mounting base fixed to the base and the clamping piece fixed to the mounting base, eliminating all the drawbacks of conventional screwing and nailing, and Panel installation can be done quickly and easily, and can be done with good appearance. In addition, since it can be installed to the main part of the building's frame, there is no need for a rim, etc., and in the case of general construction methods, construction can be done from the back side, improving the appearance as well as ease of construction. It is possible to achieve a significant improvement in
