Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for adding an additional part to a house using the panel/metal construction method in which the outer wall of the house is formed by joining wall panels using connecting metal fittings. This invention relates to an extension structure for a house that facilitates the formation of an attached foundation to receive the wall panels of the added part.

[Conventional technology]

2. Description of the Related Art Panel construction methods are often used in buildings where panels are used to form the walls, floors, roofs, etc. of houses.

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., standard modules such as 90 CII are used, as shown in Figures 1 to 3. In recent years, houses have been developed using the panel/metal construction method, which improves construction efficiency by joining large wall panels P that are 3 to 5 times larger than the original size with upper and lower connecting fittings 2A, -12B, etc. . In a house constructed using such a construction method, as shown in FIG. 3, the upper connecting fitting 2A is connected to the upper connecting fitting 2AW for a continuous wall that connects between the wall panels PSP on the upper floor, which are continuous parts of the walls, and and an upper connecting fitting 2AC for the corner located at the corner, and the lower connecting fitting 2B.
are the lower connecting fitting 2BW for the continuous wall that connects the downstairs wall panels P and P, and the lower connecting fitting 2 for the corner located at the corner.
It consists of BC. In addition, the upper metal fittings 3A are arranged on the upper surface of the two upper connecting metal fittings, and the lower metal fittings 3B are arranged on the lower surface.Furthermore, the upper metal fittings 3A are arranged with 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 the connecting metal fittings 2A-12B. For example, as shown in Fig. 1.2, two By arranging the wall panels P on the upper and lower floors, it is possible to form a rectangular parallelepiped-shaped house main body H1 shown by solid lines in FIG. 1.2.

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, as shown by the dashed line in FIG. As shown in the figure, there are cases where a wide house attachment H2 extending over the length of two wall panels P and P is added.

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.

■ It is possible to improve construction efficiency, prevent accidents such as fire, and increase safety by eliminating the use of welding, fusing, etc. when building additional buildings.

etc. are desired.

In order to solve such a problem, the present inventor used an attached connecting metal fitting to bolt the upper end of the wall panel of the house main body part H2 to the connecting metal fitting on the core without replacing the upper connecting metal fitting. I devised a method to fix it.

However, also in supporting the lower end of the wall panel P of the house attachment part H2, it is desirable to reduce the modifications made to the house main body part H1 as much as possible.

However, conventionally, the lower end of the wall panel P of the house attachment H2 has been constructed by replacing the lower connecting fitting 2B, or by welding a new member for addition to the connecting fitting.

[Problem to be solved by the invention]

However, replacing the connecting metal fittings requires attachment and detachment from the foundation and wall panels that the metal fittings are fixed to, which requires a large amount of work.In addition, welding the parts together makes on-site work difficult and reduces safety. There is an issue of being inferior.

The basic idea of the present invention is to attach the side and lower surfaces of the wall panel P via the foundation attachment fittings embedded in the attached foundation connected to the outer surface of the foundation of the existing house main body part H1, and to connect the reinforcement to the foundation attachment fittings. The purpose of the present invention is to provide a house extension structure that can increase construction efficiency and safety, reduce the impact of extensions to the main body part H1 of the house, and form a strong attached foundation with good construction efficiency. .

(Means for Solving the Problem) The present invention provides a method for forming the outer wall of a house including a wall panel whose lower end is fixed by a connecting fitting on the foundation. A house extension structure for adding up an attached part of a house that forms an outer wall including wall panels placed on an attached foundation extending from the outside surface, wherein the attached foundation is configured to extend the reinforcement passing through the attached foundation to the wall of the attached part of the house. A panel support fitting that fixes the lower end of the panel, and a foundation mounting fitting that hangs from the panel support fitting, is supported by the foundation by an anchor bin that is fitted into the outer surface of the foundation of the main body of the house, and is embedded in the attached foundation. This is an extension structure for a house that is connected to the foundation mounting bracket of an attached anchor having a base.

[Effect]

The panel support fittings of the attached anchor are attached to the li of the main body part H1 of the house.
' It is supported by an anchor pin fitted into the outer surface of B1 and coupled to a foundation mounting bracket embedded in the attached foundation B2.

Therefore, modifications to the foundation B1 of the main body part H1 of the house can be suppressed to a minimum, making the addition work more efficient and safer, and making it possible to live in the main part H1 of the house during the extension work. do.

In addition, since the reinforcement of the attached foundation is connected to the foundation mounting bracket, the effort required for reinforcing construction is reduced, and the installation accuracy of the reinforcement is increased, thereby increasing the strength of the foundation.
