Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel used as a load-bearing panel, for example in a prefabricated house.

In prefabricated houses, load-bearing panels are used that bear the load of columns and beams made of steel frames due to their architectural structure. This type of panel is constructed with a steel frame around its periphery, wooden crosspieces inserted on opposing sides, and a base material such as plywood provided on the front and back surfaces.

However, the only way to attach the base material to the steel frame is to use adhesive, which is time-consuming and inconvenient as it is not possible to nail the edges of the panel.Also, it is heavy, making it difficult to transport and assemble. Construction is not easy.

The present invention was developed based on the above circumstances, and its purpose is to provide a panel that maintains its strength, allows nailing, and reduces weight to facilitate transportation. It is something.

An embodiment of the present invention will be described below based on the drawings. In the figure, reference numeral 1 denotes a corner fitting formed by bending, for example, a band-shaped iron plate into a substantially L-shape, and each piece 1a,
A metal corner plate 2 is fixed along one side edge of 1a by means such as welding. That is, the corner plate 2 has a substantially rectangular shape, and the corner metal fittings 1 are fixed to two adjacent sides thereof. Four such corner fittings 1 are located at the four corners with their bending directions facing each other, and the corner fittings 1, 1 along the diagonal line are connected by braces 3. This brace 3 is a band-shaped iron plate, and both ends thereof are fixed to corner fittings 1 facing each other along a diagonal line via corner plates 2. That is, it is fixed to the corner plate 2 provided on the corner fitting 1 by means such as welding. Further, a through hole 4 for nailing is formed in each piece 1a, 1a of the corner fitting 1, and a nail 5a is driven through the hole 4 into a frame 5 connecting the opposing pieces 1a, 1a. That is, the outer side of the end of the frame 5 is attached to the inner surface of the piece 1a. However, the end face of the frame 5 forms a gap with the opposing piece 1a of the corner fitting 1. Thereby, the frame 5 connects the corner fittings 1 to form a rectangular body A as a whole. Note that the ends of the braces 3 are inserted into the spaces formed by the end surfaces of the frames 5, 5. Frames 5 on opposite sides,
A crosspiece 6 is inserted into the crosspiece 5 and connected to each other with nails or the like. The crosspiece 6 has a groove 7 for escaping the brace 3.
Of course, there is a Then, on the front and back surfaces of the rectangular body A, a base material 8 such as veneer plywood,
8 is attached by nailing or other means.

In the panel constructed in this manner, the four corners and diagonal lines are made of metal, and these act to strongly pull the wood inward, so that the main materials are firmly connected. The panel can easily bear loads from the vertical, horizontal, and diagonal directions, and can be used as a load-bearing panel. Also, since there are only a few metal parts, it is light in weight, and can be nailed into surrounding areas except for the four corners.

As explained above, according to the present invention, approximately L-shaped metal corner fittings are located at the four corners, and the insides of these are connected with wooden frames only on the outside of the ends to form a rectangular body, and the diagonal lines Metal braces were provided in the space between the stile ends of the corner fittings along the stile, and a base material was provided on the sides of the rectangular body, so the braces and the corner fittings pulled the stile inward toward each other to create a sufficient tension. It has strength and can be used as a load-bearing panel, and it also reduces weight, making it easier to transport and assemble, expands the area that can be nailed, and protects the corner edges of the base material with corner metal fittings. This has the effect of improving durability.
