Description

[Detailed Description of the Invention] The present invention relates to a fastener for building board materials, and particularly to a fastener for jointed construction board materials.

Conventionally, for example, joint type flat plates have been widely used as wall materials for buildings, but among these, cement-based (mixed cement, asbestos, and lightweight aggregate) joint type construction board materials that are made by hollow extrusion are particularly popular. Not only does it have fire retardant properties due to its non-combustible cement-based properties, is highly durable, and has high thermal and sound insulation properties due to the air layer in the hollow, it also has a heavy appearance, and has excellent features such as being highly water resistant. It has recently attracted attention as a versatile building material.

During construction, these building boards are long compared to building construction materials, and when used for walls, they are either vertical (attached vertically) or horizontally (standing in the width direction and used horizontally as a whole. ), but the long ones are sometimes used for ceiling panels or floor panels.

Although they are used in a variety of ways as described above, in each case, various methods have been devised for fixing the building board to the building construction material located on the back side thereof.

For example, in order to vertically construct jointed building boards for use as wall boards, several rims are installed horizontally between the upper surfaces of the pillars of the construction material, and a first long board is placed on the rim. Fit the joint-type building board vertically, fix its female part (the elongated fitting groove provided on the longitudinal side edge of the building board) to the body edge using screws or nails, and attach the female part to the body edge. The male part of the second building board (the elongated fitting protrusion provided on the side edge in the longitudinal direction opposite to the female part of the building board) is inserted, and the female part of the second building board is inserted. Use screws or nails to fix the parts to the rim, and then sequentially fix the building boards in parallel.

However, the thickness of the part of the female part where the nails should be nailed is usually several meters.
Moreover, since it is made of a relatively brittle cement-based material, if it is hammered too hard, it will break at that point, and if it is hammered too gently, a gap will be created between the building board and the rim.

In addition, since it is necessary to drive the nails in an oblique direction in order to improve the adhesion to the rim, there are drawbacks such as requiring skill in construction and prolonging the construction period.

Another method is to fix the side edge of the male part by fixing the plate-like base part to the body rim using a latching metal fitting having an O-shaped cross section and consisting of a flat plate-like base plate and a spring-like latching part. However, since the side edges of the female part side of the parallel building boards rest on the flat board, only the side edges are kept lifted from the girth, and the building boards as a whole are smooth. It cannot be stably fixed to the body rim.

The present invention has been developed in consideration of the above-mentioned drawbacks, and includes a flat plate-shaped substrate, which extends from the edge of the substrate and has an O-shaped cross section including the substrate, and has a spring property in a direction perpendicular to the substrate. an extending portion capable of sandwiching construction board materials; and an underlayment plate extending from at least a portion of the edge portion with the same thickness as the substrate and forming the same plane as the substrate. The present invention provides a construction board fastening fitting.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1a is a side sectional view of a construction board fastener 1 according to the present invention, and FIG. 1b is a perspective view thereof.

A flat board 3 extends upward from one end edge E thereof, has an O-shaped cross section including the board, has spring properties in the vertical direction, and holds a construction board 5 (FIG. 3) between them. A part of the flat substrate 3 is cut out in the center of the extending portion 2 and the edge E, and the edge E is bent by 180 degrees to form an underlay plate 4, and the underlay plate 4 and the flat plate are The shaped substrates 3 are shaped so as to lie on the same plane, and constitute the building board fastener 1.

Hole 9 connects building board material fastener 1 to building material (7 in Figure 3).
) This is the nail hole when attaching to the

In FIG. 3, a building board 5 is placed on top of a building construction material 7, the tip 6 of the male part is held between the spring-like extensions 2 of the building board fastener 1, and the underlay board 4 is placed on the building board 5. The construction board 5 is inserted between the board 5 and the building construction material 7 and is about to be fixed to the construction material 7 with nails 8 through the holes 9 provided in the flat substrate 3.

Note that the hole 10 represents a portion of the hole formed by cutting out the flat substrate 3 to make the underlay plate 4.

After fixing the building board fasteners to the building construction materials with nails 8, place the female side edge of the second building board on the flat board and fit it into the male part 6 of the first building board. They will be combined and placed side by side.

Figures 2a and 2b show other examples of the construction board fastener, with Figure 2a showing a side sectional view and Figure 2b showing a perspective view thereof.

In this example, the base board 4 is widened to more stably fix the building board 5, but the base board 4 extends over the entire width of one end edge E of the flat board 3.

The present invention relates to a construction board fastener having the structure described above, and by using the fixture, both side edges of the construction board can be fixed by riding on the flat board and underlayment that have the same thickness and are on the same plane. Therefore, for example, it is not necessary to cut out a portion of the construction board material corresponding to the thickness of the flat board, the fixing operation is easy, and the entire structure can be fixed smoothly.

In addition, the extension part 2 has spring properties and can hold construction board materials.
Since it forms a resilient spring integrally with the flat substrate 3, when a building board is inserted, it can be firmly clamped and fixed.
