Description

[Detailed description of the invention] This invention is a fixing metal fitting for building materials that can easily and quickly fix indoor and outdoor building materials that are connected and laid using the tongue-and-groove method without exposing the nails to the outside. Regarding.

In recent house construction, indoor walls, floors, and ceilings, as well as outdoor walls, are made of wood to make use of the texture of wood and create a calming feel. Among the building materials used for outdoor paneling,
A tongue-and-groove joint in which a protruding strip called a rabbet is provided on one side of the plate in the longitudinal direction, and a groove into which the protruding strip fits is formed on the other side, and these are laid in parallel while making the uneven fit. Building materials made by this method for boarding are widely used in general construction because they have no gaps in the joints, are less prone to deformation, and have a beautiful finish with no nail heads exposed on the surface of the building materials.

By the way, as a conventional means of fixing building materials using tongue and grooves, as shown in Figure 1A,
The building material 2a is attached to the building material 2a, a nail 4 is driven into the base of the tongue 3 of the building material 2a to fix it, and the concave groove 5 of the building material 2b adjacent to the tongue 3 is fitted and assembled. As shown in Figure B, the building material 2c is fixed to the base material 1 by driving nails 4 into the grooves 6 of the building material 2c,
The tongue 7 of the building material 2d adjacent to the groove 6 of the building material 2c
The method used is to fit and assemble the parts.

However, when the conventional method of fixing building materials using only nails as described above is adopted, it is necessary to accurately drive the nails 4 into the roots of the tongues 3 of the building material 2a or into the grooves 6 of the building material 2c, which may result in operator inexperience. Not only is there a risk of accidentally breaking the edge of the tongue 3 or groove 6, but also use tools such as nail tightening each time to prevent the head of the nail from interfering with the fitting of the uneven fitting of the building material 2. There was a problem in that it was necessary to perform caulking work, which significantly reduced work efficiency.

The present invention focused on the problem of fixing building materials using the conventional tongue-and-groove method, and was devised to provide a fixing fitting that can easily and quickly fix building materials. , a mounting plate part attached to a base material such as an outer wall and having a communication hole for a nail fixed to the base material, a locking plate part extending parallel to the mounting plate part, and the mounting plate part and the locking plate part. A metal fitting for fixing plate-shaped or block-shaped building materials connected by a tongue-and-groove method to a base material, comprising a connecting part that connects the plate parts at a butt gap between the building materials, and the fitting is provided with a connecting part that connects the plate parts in the butt gap between the building materials. It is characterized by a structure in which a locking piece is provided to be inserted into the groove of the building material, and an acute-angled protrusion is formed on the opposite side of the locking piece to be driven into the base of the convex strip of the building material.

Hereinafter, specific contents of the present invention will be explained in detail with reference to embodiments shown in the accompanying drawings.

Figures 2 to 4 show an example of the fixing bracket of the present invention. Figure 2 is a perspective view of the fixture, Figure 3 is a plan view of the fixture, and Figure 4 is a diagram of the fixture. A side view of each metal fitting is shown.

In each of these figures, the fixture 11 is made by punching out a metal plate, for example, a galvanized iron plate.
It is constructed by bending into a letter shape, and includes a mounting plate part 12 that is attached to the base material 1 of a conventional building, and a mounting plate part 12 that stands up from one side of the mounting plate part 12 and is located in the opposing gap between the building materials when installed. The connecting portion 13 and the connecting portion 13
It has a locking plate part 14 extending in parallel with the mounting plate part 12 from the upper edge thereof.

The mounting plate part 12 has an insertion hole 15 through which the nail 4 is passed through at approximately the center thereof, and the periphery of the insertion hole 15 has a slight slope to form a surface attached to the base material 1. At the same time, a tongue piece 17 cut out from the notch 16 of the connecting part 13 and the locking plate part 14 is provided on the edge side of the mounting plate part 12 where the connecting part 13 is connected. is extended, and the tongue portion 17 is configured to clamp the edge 19 of the groove 18 of the building material 2 in the gap t between the tongue portion 17 and the locking plate portion 14, as shown in FIG.

The locking plate portion 14 has substantially the entire surface covered with the concave groove 1 of the building material 2.
The locking piece 20 is formed on the locking piece 20 to be inserted into the connecting portion 8 , and is provided with an acute-angled protrusion 21 that protrudes toward the opposite side of the connecting portion with the connecting portion 13 .

The fixing metal fitting of the present invention has the configuration as described above, and to explain the case in which it is used to fix building materials, first, it will be compared with another fixing metal fitting 22 as shown in Fig. 6, that is, the fixing metal fitting of the present invention. A mounting plate part 24 made of a similar metal plate material and having a nail insertion hole 23 in the center, an upright piece part 25 standing vertically from one side of the mounting plate part 24, and an upright part 25 extending from the upper edge of the upright piece 25. One side of the building material 2A is fixed to the base material 1 using a building material end fixing fitting having two acute angle protrusions 26 protruding in parallel with the mounting plate part 24, and fixed to the groove 18 of the building material 2A. The insertion part 20 of the metal fitting 11 is inserted, the mounting plate part 12 is attached to the base material 1, and the mounting plate part 12 is fixed with nails 4. Next, building material 2A
While fitting the tongue 27 of the building material 2B to be fixed adjacent to the building material 2A into the groove 18 on the side of the building material 2A, attach it to the base material 1, attach a batten to the groove 18 side of the building material 2B,
Tighten the board by nailing it to the building material 2A side.

At this time, the fixing fitting 1 that fixes the building material 2A
The acute angle protrusion 21 of No. 1 is driven into the base of the tongue 27 on the building material 2B side by the reaction force from the building material 2A, and the building material 2B engages with the building material 2A by tongue and groove fitting and into the fixing metal fitting 11. It is held by twisting.

Therefore, in such a state, the concave groove side of the building material 2B is held down by the fixing fitting 11 of the present invention, and the building material 2B is
If C, 2D, etc. are sequentially fastened to the base material 1 using the same procedure, boarding can be easily performed using a strong and beautiful tongue-and-groove method.

In addition, in the above embodiment, a board material fixed by tongue-and-groove method is used as a building material. However, the fixing fittings of the present invention can be used for walls, ceilings, floors, etc. by appropriately changing the dimensions of each part. It can be applied to fixing interior materials such as wood, plastic, etc.
It can also be used to fix exterior materials, including cement boards and blocks of these materials, to the exterior walls of buildings.

As described above, the fixing fitting of the present invention connects the engagement plate part that engages with the concave-convex fitting part of the building materials connected by the tongue-and-groove method, and the fixing plate part that is nailed to the base material of the building in parallel. Since these parts are integrally formed with a connecting part that connects each part in the gap between the building materials, there is no risk of accidentally damaging the joints of the building materials, as in the case of conventional fixing of building materials using only nails. This makes nailing work easier, and since the building material to be fixed is stably held by the adjacent building materials and fixing metal fittings that have been fixed to the base material in advance, continuous construction using the fixing metal fittings is facilitated. Coupled with the fact that tools such as nail tightening are not required, this method has the excellent effect of greatly improving the efficiency of fixing construction materials.
