Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a house using the panel/metal construction method in which the outer wall of the house is formed by joining wall panels with connecting metal fittings.
This article relates to a house extension method that can streamline construction.

[Conventional technology]

2. Description of the Related Art Panel construction methods, in which panels are used to form the walls, floors, W-shaped bodies, etc. of houses, are often used in buildings.

Also, in buildings using this panel construction method, in addition to houses using the frame construction method in which panels are attached to a frame body previously formed using columns, beams, etc., as shown in Figures 1 to 3, for example, A large wall panel P that is 3 to 5 times the width of the standard module,
In recent years, houses have been developed using the panel/metal construction method, which improves construction efficiency by joining upper and lower connecting metal fittings 2A, 2B, and so on.

In a house built using such construction method, as shown in Fig. 3, the upper connecting fitting 2A is the upper connecting fitting 2AW for the continuous wall connecting between the upper floor wall panels P, which are the connecting parts of the walls. and an upper connecting fitting 2AC for the corner located at the corner, and the lower connecting fitting 2B is located at the corner with the lower connecting fitting 2BW for the continuous wall connecting between the downstairs wall panels P and P. and a lower connecting fitting 28C for the corner. The upper connecting fitting 2A has an upper fitting 3A on its upper surface and a lower fitting 3B on its lower surface, and the upper fitting 3A is
Upper metal fittings 3AW for continuous walls and corners.

3AC and the lower metal fittings 3B also include lower metal fittings 3BW and 38C for continuous walls and corners, respectively.

In the above-mentioned panel/metal construction method house, the outer wall is formed by connecting the wall panels P with two connecting metal fittings..., 2B..., for example, as shown in Fig. 1.2. , two wall panels P... are arranged on each side, one on the upper floor and one on the lower floor.
1 can be formed.

However, after the house is constructed, it may become necessary to extend the house due to changes in the living conditions of the residents. In addition, such an extension involves adding a house attachment part H2 with the width of one wall panel P to the existing house main body part H1, as shown by the dashed-dotted line in Figure 1 (al, (bl). Sometimes, as shown in FIG. 2 (al), a wide house attachment H2 extending over the length of two wall panels P%P may be added.

Furthermore, the roof of the house attachment H2 is also shown in Figure 1 (a).
In some cases, a double-sided roof is used as shown in FIG. 1 (b) and FIG.

On the other hand, in the case of such an extension, ■ It is possible to carry out the extension work while continuing to live in the main body part H1 of the existing house.

■ Avoid damaging the interior of the main body of the house H1 as much as possible.

■ Scales improve construction efficiency, prevent fires and other accidents, and increase safety by eliminating the need for welding or fusing during building additions.

etc. are desired.

However, conventionally, when building an addition to a house using this type of panel/metal construction method, construction was carried out by replacing the connecting metal fittings or by welding new members for the addition to the connecting metal fittings. .

[Problem to be solved by the invention]

However, replacing the connecting metal fittings involves attaching and detaching the wall panel to which the connecting metal fittings are fixed, which is a large-scale work, and welding the parts also makes on-site work difficult and reduces safety. There is an issue of being inferior.

The present invention is based on bolting the attached connecting fittings for forming the house attachment part H2 to the connecting fittings 2A on the existing house main body part H1, thereby increasing construction efficiency and safety. In addition, it is an object of the present invention to provide a house extension method that can reduce the influence of extensions on the main body part H1 of the house and meet the above requirements.

C! Means for Solving JLA] The present invention provides a method for forming the outer wall of a house by joining the top and bottom of wall panels placed side by side using connecting fittings placed between them. A method for expanding a house using panels to form an external wall, the upper end of the wall panel of the house attachment being attached to an attached connecting bracket bolted to the upper connecting bracket of the main body of the house. This is a house extension method characterized by connection.

[Effect]

The attached connecting fittings are attached to the connecting fittings on the house main body part H1 by bolts and connect the wall panel P of the house attachment part H2, so the connecting fittings 2 on the house main body part H1 are attached to the connecting fittings on the house main body part H1.
(In addition to preventing damage caused by the addition of the main body part H1 of the house, improving workability, and making it possible to live in the main part H1 of the house even during the construction of the addition,
There is no work such as welding or fusing, improving construction safety.
