Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention suppresses the modification of an existing part in a house of a panel / metal fitting method in which a wall panel is joined using a connecting fitting to form an outer wall of the house. At the same time, the present invention relates to an extension structure of a house that can conveniently support the roof frame material of the additional portion.

[Conventional technology]

The building of the panel construction method that uses the panels to form the walls, floors, roofs, etc. of houses is often used. Also in this panel construction method, in addition to the frame construction method in which the panel is attached to the skeleton formed in advance using columns, beams, etc.
As shown in FIG. 3, for example, a large wall panel P having a width of 3 to 5 times that of the reference module, which is 90 cm, is attached to the upper and lower connecting fittings.
Houses with a panel / metal fitting construction method have been developed in recent years that have improved construction efficiency by being joined by 2A ..., 2B. In the case of a house constructed in this way, as shown in FIG.
The upper connecting metal fitting 2A includes an upper connecting metal fitting 2AW for connecting a wall connecting the upper wall panels P, P which is a wall connecting portion, and an upper connecting metal fitting 2AC for a corner located at a corner. The lower connecting fitting 2B is composed of a lower connecting fitting 2BW for connecting walls connecting the lower floor wall panels P, P and a lower connecting fitting 2BC for corners located at a corner. The upper metal fitting 3A is arranged on the upper surface of the upper metal fitting 2A, and the lower metal fitting 3B is arranged on the lower surface thereof.The upper metal fitting 3A is an upper metal fitting 3AW for connecting walls and corners. 3AC, and the lower metal fitting 3B also includes lower metal fittings 3BW and 3BC for the wall and corner, respectively.

In the house of the panel / metal fitting method, the outer wall is formed by connecting the wall panels P by the connecting metal fittings 2A ..., 2B ... In this way, for example, as shown by the solid lines in FIGS. Each of the two wall panels P ... is arranged upstairs and downstairs.
A rectangular parallelepiped house body H1 shown by a solid line in FIG. 2 can be formed.

However, after the house is built, it may be necessary to expand the house due to changes in the living conditions of the resident. In addition, such an extension may add a wide house appendage H2 extending over the lengths of the two wall panels P, P, as indicated by the chain line.

As for the roof part of the additional part H2 of the house, as shown in Fig. 1, when using a flat roof, as shown in Fig. 2,
Both swirl roofs may be used.

Further, in such a wide house appendage H2, there may be a case where a partition wall is not provided inside the house appendix H2 in a wide space, and at this time, a roof frame structure for forming the roof of the house appendix H2. It is necessary to hold the material in its intermediate position. Moreover, in the formation of such a house appendage H2, it is desirable to minimize the remodeling of the house main body H1 when the building is added.

Conventionally, in such a case, the connecting metal fitting of the main body H1 of the house is replaced with a pillar, and the roof frame is supported by the pillar.

[Problems to be Solved by the Invention]

However, in such a modification, the wall panel P of the main body of the house is attached and detached, which leads to a large amount of additional construction work.
There is a problem that the interior is damaged and it becomes difficult to live in the house body H1 during the extension construction.

It is an object of the present invention to provide an extension structure of a house that can solve the above-mentioned problems by attaching an attachment pillar by using a connecting fitting on the main body H1 of the house.

[Means for Solving the Problems]
