BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting member for a building board used for fastening a flat building board such as a ceramic outer wall material to the side of a building, and to fixing such a connecting member. It relates to a building plate and its fastening structure.

[0002]

2. Description of the Related Art As a building exterior work, a ceramic building board is fastened to the side of a building. For example, in the horizontal construction method in which the longitudinal direction of the building board is fixed to the skeleton side with the longitudinal direction being the horizontal direction (horizontal direction), first, as shown in FIG. 3
A vertical rim 4 is attached to the position of the pillar 1 or the stud 2 to secure a ventilation layer, and a building board (not shown here) is fixed to the vertical rim 4 by nailing or the like. In the vertical stretching method in which the longitudinal direction of the building board is fixed to the skeleton side with the longitudinal direction being the vertical direction (vertical direction), as shown in FIG. Are mounted in a plurality of stages at predetermined intervals in the horizontal direction, and a building board is fastened to the lateral trunk edge 5. In this case, it is necessary to secure a ventilation passage by providing a gap S between the adjacent left and right lateral trunk edges 5, 5.

On the other hand, as a method for fastening a building board, there is a metal fitting construction method using a dedicated fastener 60 as shown in FIG. In this fastener 60, the contact surface 61a on the skeleton side and the support surface 61b supporting the back of the building board are positioned parallel to each other at a predetermined distance via the connecting portion 61c and the bent piece 61d. The support surface portion 61b has two opposing horizontal side edges 31 of two building boards 30A and 30B positioned in the vertical direction.
Attachment pieces 62 are provided in the horizontal direction, and can be fitted in the mating portions (see also FIG. 12) formed on A and 31B in a mutually engaged posture.

[0004] In the case of using such a fastener 60, a sufficient ventilation layer S is provided between the skeleton side and the back surface of the building board by the fastener 60 attached to the vertical waist 4.
c is secured. FIG. 12 shows a method of laterally fastening the building board 30 using the fastener 60. Building board 30
At the time of fastening, the lower-order building board 30B is placed horizontally and fixed, and the lower side of the mounting piece portion 62 of the fastening fitting 60 is fitted to the upper horizontal side edge 31A of the building board 30B to secure the fastening fitting 60. After the positioning of the fastener 6
0 is fixed to the vertical rim 4 by a screw or a nail 50, or to the pillar 1 or the stud 2 via the vertical rim 4, and then the lower horizontal edge 31A of the upper building board 30A is fixed first. The metal fitting 60 is placed sideways in a posture fitted to the upper part of the mounting piece 62. Then, the building board 3 placed horizontally
After fitting the next fastener 60 in the same manner to the upper horizontal side edge 31B of 0A, the fastener 60 is fixed to the pillar 1 or the stud 2 with screws or nails 50. Less than,
By repeating this operation, the building boards 30 are laid horizontally in multiple stages in the vertical direction on the side of the building, and a decorative outer wall is constructed.

[0005] In this fastening method, unlike the case of nailing, there is no risk of damaging the surface of the building board 30, and the fastening 60 is not visible from the outside, which is a very favorable appearance. The attachment state is obtained. In addition, since a sufficient ventilation layer Sc is formed on the back surface of the fixed building board 30, the occurrence of dew condensation can be suppressed.

[0006]

However, in the case of the above-mentioned conventional metal fittings construction, it is necessary to assemble a large number of the vertical rims 4 in order to form the ventilation layer Sc. It greatly affects the construction period. In addition, since nailing is usually performed only at the peripheral edge of a building board, in the case where a prescribed construction method is not followed, it may occur that the wind resistance is insufficient. In addition, it is necessary to repair and repair the nail head portion, which has an aesthetic problem.

In the fastening method using a fastener,
An operation of hitting a large number of fasteners to the pillar 1 or the stud 2 is required. Furthermore, in the case of horizontal stretching, the fastening metal used is a structure that can be attached to the joints (lower real part and upper real part) formed on the upper and lower horizontal side edges of the building board. If a large surface load (wind pressure, etc.) is applied to the front or back side of the attached building board,
The load is carried by the upper and lower fasteners. Currently, the construction boards are relatively small in area per sheet, and there is no particular inconvenience. In the case where the fastening method using the fastening fitting is adopted, the load carrying only by the fastening fitting portions arranged on the upper and lower horizontal side edges of the building board does not provide a sufficient supporting force, and the fastening portion is not provided. It is anticipated that breakage at the surface may occur.

The present invention has been made in view of the above circumstances, and has as its object to fix a building board directly to a pillar or stud (structural frame) without using a rim.
Despite the fastening of the building board by the direct upholstery method, it is possible to secure a sufficient ventilation layer between the structural skeleton and the back of the building board, and it is possible to omit the work of assembling the fuselage rim. An object of the present invention is to provide a novel fastening structure of a building board which can largely save labor.

Another object of the present invention is to provide a joint between adjacent building boards even when an unexpected load (surface load) is applied from the front side or the back side of the building board fastened to the side of the building. A new fastening structure for building boards, which prevents excessive load concentration on the building boards, and does not cause instability in the fastening condition even if the building boards have a large surface area To provide. Still another object of the present invention is to provide a novel connecting member for building boards and a building board to which the connecting members are fixed, for constructing the above-described fastening structure.

[0010]

According to the present invention, the above object is achieved by using a building board having a connecting member for a building board unique to the present invention fixed to the back surface. The building boards themselves may be those conventionally used. The connecting member for a building board is a long member as a whole, and has the following configuration, and a part (extending piece) is fixed to a pillar or a stud on the building frame side with a screw or the like. Thereby, the building board is directly stuck to the building side (straight construction). In addition, by making the elongated members connected to each other, the building board is fastened to the building frame side in a vertically continuous state.

[0011] The building board connecting member having the above-described structure is fixed to the back surface of a required building board with at least the extension piece projecting from the side edge. At this time, preferably, a plurality of the connecting members for building boards are fixed to the back surface at intervals corresponding to the intervals between the vertical members such as pillars and studs on the building side to which the building boards are to be fastened. . The fixing method is optional, but when the building board is a ceramic building board, the fixing method using the tip-extending driving rivet is advantageous in that the work is easy and a stable fixing state can be obtained. As other fixing methods, there are a method of fixing with an adhesive and a method of integrally molding when manufacturing a building board.

When the above-mentioned building board is fastened to the building frame side, the extending piece of the building board connecting member in which the lower building board (first building board) is fixed to the back surface is used. The building is placed sideways so as to be in contact with the building skeleton side (preferably a pillar or stud, but may be another member), and in this state, the extension piece is fixed with a screw or the like. It is directly fixed to the building frame side with the fixture. Thereby the first
The work of fastening the building board is completed. Hereinafter, the required number of sheets are fastened in the horizontal direction.

A lower horizontal side edge of the same type of building board (second building board) is fixed to the back surface along the upper horizontal side edge of the fastened first building board. The engaging tongue of the member is placed in a state of being inserted into the locking hole formed in the connecting member for the building board of the first building board, and the extended piece of the connecting member for the building board is placed on the building frame side. Assume an abutting posture. In this state, as in the case of the first building board, the extended piece portion is directly fixed to the building frame side with a fastener such as a screw. Thus, the work of fastening the second building board is completed. Hereinafter, the necessary number of sheets are fastened in the horizontal direction and the upper direction in the same manner.

In the above-mentioned fastening structure, the connecting member for building boards fixed to the back of the building board is directly fixed to the building frame side, which is compared with the conventional fastening structure using the fastener. Therefore, the work of attaching a large number of fasteners can be omitted, so that the work of fastening is labor-saving.
In addition, because of the presence of the rising pieces formed at one end of the connecting member for building boards, a sufficient ventilation layer is secured between the building frame side and the back of the building boards, which was required by the conventional straight-line construction method. There is no need for a "border edge", which simplifies work and saves labor.

[0015] Further, the connecting member for building boards is a long one, and a driving rivet, preferably a tip-expansion type, is used in multiple rows in the width direction with its main body part being in close contact with the back surface of the building board. Since the building board is fixed in place, the strength of the building board itself can be greatly improved, and a stable fastening mode can be obtained even for a building board having a large surface area.
Further, even when a large surface load is applied to the back side of the fastened building board, the load is mainly generated by the connecting portions (i.e., the connecting portions of the building board connecting members, not by the upper and lower horizontal side edges of the building board). Carried by the engaging tongue and the engaging hole).
It does not act on the joints (lower solid part and upper solid part) formed on the upper and lower horizontal side edges of the building board. For this reason, breakage of the joint portion of the building board can be avoided.

As described above, the material of the building board to be fastened is not particularly limited. However, in general, a ceramic-based board is liable to crack due to a surface load when the board has a large area. Considering this, a ceramic building board is extremely effective as a target building board of the fastening structure of the present invention. Further, it is a preferable embodiment that actual processing is performed on at least the upper and lower horizontal side edges for four rounds, because rainwater can be prevented from intruding from between the adjoining building boards.

The structure for fastening a building board according to the present invention has an advantage that any vertical member of a building can be effectively used. Therefore, in the case where the target building is a wooden substructure such as a framing wall construction method (two-by-four construction method) or a framing method, or a building having a steel frame substructure, the vertical members constituting the substructures ( There is a merit that the building board can be easily and securely attached by using the vertical ground.
