Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a wall panel connection structure that makes it possible to form a bulge in a non-rectangular house using wall panels whose width is an integral multiple of a reference module. .

[Conventional technology]

BACKGROUND ART Conventionally, there are a frame construction method and a panel construction method as construction methods for constructing houses, particularly prefabricated houses whose construction members are produced in advance in a factory or the like.

The frame construction method is, for example, in the case of a two-story house, as shown in Fig. 17, a frame structure F is assembled using floor beams 4A, roof beams 4B, etc., which have a difference in body length between through columns 3A, and then A wall panel PS- is attached to this frame structure F. In houses built using this frame construction method, the frame structure F has high strength and excellent rigidity, so the wall panel PS is generally not required to withstand the strength, and therefore, it is possible to handle construction while reducing weight. In order to improve performance, for example, a frame made of wooden frame materials is used, and the width thereof is also formed as a small wall panel with a width of about 1 to 3 times that of the reference module M.

In addition, the panel construction method, as shown in Fig. 18, is a wall panel PL.
The house is assembled by connecting the parts using the connecting fittings 6.

In addition, since this panel construction method is based on the assumption that no pillars will be used, the wall panel PL uses a frame made of steel frame materials arranged in a rectangular shape, and the vertical axial force is borne by the vertical frame materials. .

In addition, since the wall panel PL of this panel construction method is a heavy responsibility, it is assumed that it will be constructed mechanically using a crane etc. Therefore, a large wall panel with a width of 3 to 6 times the width of the standard module M is adopted. be done.

On the other hand, in recent years, non-rectangular bulges are sometimes formed on houses in order to match the shape of the site or due to the diversification of residents' preferences.

In such cases, conventionally, a frame structure is formed whose outer periphery is bent to match the shape of the bulge, and a small wall panel is attached to this frame structure, or a large frame structure with a bent shape or slanted side edges is formed. This was done by creating new wall panels and connecting them using connecting fittings.

[Problem to be solved by the invention]

However, producing such frame structures and irregularly shaped large wall panels requires a lot of effort.

An object of the present invention is to provide a wall panel connection structure capable of forming a non-rectangular bulge using a standard wall panel having a width that is an integral multiple of a reference module.

[Means to solve the problem]

The present invention provides a beam on the upper surface of a wall panel that is inclined obliquely in a dogleg shape, has a gap at the bent part, faces each other, and has a width that is an integral multiple of the reference module. A first fixing piece is fixed to the end face of the beam on the top surface of one wall panel facing the gap, and a first fixing piece is fixed to the end face of the beam on the top surface of the other wall panel facing the gap. A connecting fitting having a second fixing piece and a joint piece having a beam attachment part that joins the first and second fixing pieces and fixes the end face of another beam arranged with its end face facing the gap. This is a wall panel connection structure that is connected using.

[Effect]

Since a wall panel having an integral multiple of the standard module, that is, a standard wall panel, can be used, there is no additional requirement for wall panels, and productivity is excellent. Further, the wall panels face each other diagonally with a gap between them, and the ends of the beams fixed to the upper surface of the wall panels facing the gap are fixed to the first and second fixing pieces of the connecting fittings, and the first A beam attachment part for fixing another beam whose end face faces the gap is provided on the joint piece that connects the second fixing piece. Therefore, this other beam is integrated with the beam on the upper surface of the wall panel via a connecting fitting to reinforce the structure of the bulge.

Additionally, since the length of the splices can be set freely, the gaps that occur when using standard wall panels can be adjusted, increasing flexibility in wall panel placement.

A small wall panel PS2, which is twice as long as PS2, and a large wall panel PL3, which is three times as long as PS2, are used to connect the wall panels. Further, on the upper surface of the base wall panel P, the beams 4-

The figure shows the case where it is installed in an opening 8 times the length.

In this way, by using wall panels of standard dimensions and connecting the beams 4 on the upper surface of the wall panels, various non-rectangular shapes of bulges Ha can be formed. It can be formed by matching only the shape of the gap N with the shape of the gap N.

In addition, the length of the joint piece 74 of the connecting fitting 7 is adjusted to reduce the gap N.
By changing the width of the bulge 8, the degree of freedom in designing the bulge Ea can be increased.

〔Effect of the invention〕

Since we use wall panels that are an integral number of the standard module, that is, Shiho's wall panels, there is no need to create new wall panels, resulting in excellent productivity. Other beams whose end faces face can be fixed together with the connecting fittings, improving workability and reinforcing the bulging ε5o structure.

Also, since the length of the splices can be set freely, the gaps that occur when standard wall panels are used can be adjusted, increasing flexibility in wall panel placement.
