Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a structure for attaching building boards to a base material through fixtures without directly nailing the building boards.

(Prior art and its problems) Conventionally, for example, Japanese Utility Model Application Publication No. 48-43405 has been proposed as a mounting structure for building boards that is attached to the base material through a fixture without directly nailing the building boards. There is.

This method is preferable in appearance because the fixtures are not visible from the building board side.

However, it is necessary to provide the male and female ends of the building board (panel), but the building board is not made of inorganic materials such as asbestos cement silica board, asbestos slate, slag plaster board, wood chip cement board, etc. Since it is hard and brittle, if the projecting piece is made thin, there is an extremely high risk of chipping during cutting to form male and female seeds, or during transportation or construction.

Further, even if the actual processing is performed with high precision, the actual pieces may not fit together properly due to unevenness or warping of the base material. Therefore, a real structure with a certain amount of play is used, but this has the problem that rattling and gaps occur and it cannot be applied to places where impact resistance, earthquake resistance, or water resistance are required.

An object of the present invention is to provide a building board mounting structure that uses mounting tools but can solve the above-mentioned conventional problems.

(Means to Solve the Problems) In order to achieve the above object, the building board mounting structure of the present invention has a base material and a projecting piece extending from the back side at one end, and a projecting piece extending from the back side at one end. A building board having a cutout portion that fits into the projecting piece portion at the bottom and a locking groove provided near the cutout portion on the back side, and an L-shaped piece portion having an outward opening on one side of the base. and a fixture having a locking piece protruding from the base on the other side of the base, the fixture nailing and fixing the base to the base material, and the building board having the locking groove. is fitted and locked into the locking piece of the fixture, and the projecting piece is held in contact with the L-shaped piece of the other fixture, and in the same manner, a plurality of building boards were attached to the base material in sequence.

(Example) Next, the present invention will be explained with reference to drawings which are examples.

1 to 3 show a first embodiment of a building board 1, a fixture 7, and a mounting structure thereof.

The building board 1 is made of an inorganic material like the conventional one, and has a projecting piece 2 projecting laterally from the base material side (lower side in the drawing) at one end thereof, and a projecting piece 2 projecting laterally from the base material side (lower in the drawing) A notch 4 is provided on the base material side of the end.

The length L of the projecting piece 2 is greater than the length l of the notch 4, and the height H is smaller than h by the thickness of the L-shaped piece 10 of the fixture 7, which will be described below.

Further, on the base material side of the building board 1, a locking groove 5 is provided near the notch 4 and is inclined in the opposite direction to the notch 4.

On the other hand, the fixture 7 is made of a metallic elastic material such as a galvanized iron plate, and includes a base 8 having a nail hole 9, and a substantially L-shaped piece 1 rising almost vertically from one side of the base 8.
0, and a locking piece 12 inclined in the opposite direction to the L-shaped piece 10 from the other side.

Next, a method for attaching the building board 1 to the base material 14 using the fixture 7 having the above structure will be explained with reference to FIG. 1.

The L-shaped piece 10 of the fixture 7 is positioned at the lowest end of the base material 14, and the fixture 7 is attached to the base material 14 with nails 15 through the nail holes 9. Then, the lower end of the lowermost building board 1 is fixed by fitting the locking groove 5 of the building board 1 into the locking piece 12 and simultaneously fitting the notch 4 into the L-shaped piece 10.

Next, the L-shaped piece 10 of another fixture 7 is applied to the projecting piece 2 of the building board 1, and the fixture 7 is attached to the base material 14 with nails 15 in the same manner as described above.
The upper and lower ends of are fixed to the base material 14.

Then, in the same manner as described above, the locking groove 5 of the other building board 1 is fitted into the locking piece 12 of the second fixture 7, and at the same time, the notch 4 is fitted into the L-shaped piece 10. , one end of the second building board 1 is fixed. Hereinafter, the building board 1 is sequentially attached to the base material 14 by the method described above.

Figures 4 and 5 show a second embodiment of the building board and fixture.

As is clear from a comparison with FIG. 1, the building board 1' is provided with grooves 3 in the width direction on the projecting piece 2, and the locking grooves 5 are bent toward the projecting piece 2 side. The locking groove 6 is shaped like a locking groove 6. In this case, the width L' of the vertical part 6a on the base material side is the width L' of the horizontal groove part 6b.
The width is wider than the width l′ of .

On the other hand, the fitting 7' is attached to the tip of the L-shaped piece 10.
It has a locking protrusion 11 that fits into the groove 3, and the other end of the base 8 is bent at a right angle in the same way as the L-shaped piece 10, and the tip of the locking piece 12 is bent outward. , a locking protrusion 13 is provided.

In order to attach the building board 1' to the base material 14 using this fixture 7', the wide vertical portion 6a of the locking groove 6 is attached to the locking protrusion 13 of the fixture 7'.
Then, the building board 1' is moved and the locking protrusion 13 is fitted into the lateral groove part 6b. It fits into the protruding piece part 2 of. In this case, the locking protrusion 11 is fitted into the groove 3 of the protrusion 2.

Note that the grooves 3 may be provided on the projecting piece 2 of the building board 1, and the shape of the fixture 7 may be changed accordingly. Further, the fixtures 7, 7' may be manufactured by extrusion molding of aluminum or by molding of synthetic resin. Furthermore, the L-shaped piece part 10 and the locking piece part 12 are connected to the building board 1,
In order to firmly fix these when engaged with 1', it is preferable to bend them slightly inward.

Furthermore, in the embodiment, the building boards 1 are stretched horizontally and connected vertically, but the construction can also be applied to a case where they are stretched vertically and connected horizontally.

(Effects) As is clear from the above explanation, according to the present invention, what is provided at both ends of the building board is not a male part and a female part as in the conventional case, but a protrusion part and a notch part. In addition, since the locking grooves are narrow, not only is it easy to form, but even if the building board is made of inorganic material, it will not chip during forming, transportation, or construction. It never happens.
