Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention suppresses remodeling of existing parts of houses using the panel/metal construction method in which the outer walls of the house are formed by joining wall panels using connecting metal fittings. The present invention also relates to an extension structure for a house that can conveniently support roof frame members of an extension 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., as shown in Figs. A large wall panel P that is 3 to 5 times the width of
In recent years, houses have been developed using the panel/metal construction method, which improves construction efficiency by joining the upper and lower connecting metal fittings 2A to 2B. In houses constructed using this method,
In the case shown in FIG. 3, the upper connecting fitting 2A is connected to the upper connecting fitting 2AW for the continuous wall connecting between the wall panels P and P on the floor that are connected to each other, and the upper connecting fitting 2AW for the continuous wall connecting between The lower connecting fittings 2AC include the upper connecting fittings 2AC, and the lower connecting fittings 2B include the lower connecting fittings 2B for the continuous wall connecting between the downstairs wall panels P, P.
It consists of W and a lower connecting fitting 2BC for the corner located at 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 has an upper fitting 3A for continuous walls and a corner.
W and 3AC, and the lower metal fittings 3B also include lower metal fittings 3BW and 38C for continuous walls and corners, respectively.

In this way, in the house constructed using the panel/metal fitting method, the outer wall is formed by connecting the wall panels P with the connecting fittings 2A-, 2B-. By arranging two wall panels P- on each surface, one on the upper floor and one on the lower floor, a rectangular parallelepiped-shaped house main body H1 can be formed as shown by the solid line 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, such an extension may include adding a wide attached part H2 to the house spanning the length of the two wall panels P and P, as shown by the dashed line.

Furthermore, as for the roof of the house attachment H2, as shown in FIG. 1, when a low M root is used, as shown in FIG. 2, a double-sided roof may be used.

In addition, in such a wide house attachment part H2, there is a case where a house attachment part H2 with a wide space is formed without providing a partition wall inside thereof, and in this case, the house attachment part H2 is
It is necessary to hold the roof frame members for forming the roof in an intermediate position.

Moreover, in forming such a house attachment part H2, it is desirable to minimize the amount of remodeling required when adding to the house main body part H1.

Conventionally, in such a case, the connecting fittings of the house main body part H1 are
It was replaced with a column, and the roof frame member was supported by this column.

[Problem to be solved by the invention]

However, such remodeling involves attaching and detaching the wall panel P of the main body of the house, which requires large-scale addition construction.
There was a problem in that it damaged the interior and made it difficult to live in the main body part H1 of the house during the extension construction.

An object of the present invention is to provide an extension structure for a house that can solve the above problem by attaching an attached column using a connecting fitting on the main body part H1 of the house.

[Means to solve the problem]

The present invention relates to a panel/metal fittings method in which the outer wall of a house is formed by joining the upper and lower sides of wall panels placed side by side using connecting fittings placed between them, and the outer surface of the connecting fittings is used to connect the house main body to the house main body. In this house extension structure, an attached part of the house is added that has a roof frame member that extends parallel to the outer wall of the house, and the above-mentioned upper connecting metal fittings are attached to a vertical piece that supports the side surface of the floor panel, and a horizontal upper part of the upper end of the vertical piece. a lower piece, which is provided at the lower end of the vertical piece and which attaches to the lower surface the lower metal fittings that fix the upper surfaces of the two downstairs wall panels and each side of the upper part of the wall panels; A column-mounted bracket, a bottom plate, and a column that connects the column-mounted bracket and the bottom plate, each having a bracket that is positioned and connects the upper and lower pieces, and fixing pieces that are bolted to the brackets on both sides of the vertical mounting piece. This is an extension structure for a house, in which the roof frame member of the attached part of the house is supported by the attachment piece of the attached pillar, which has two pieces and is erected by anchor bolting to the bottom plate.

[Effect]

A column-mounted metal fitting bolted to the upper connecting metal fitting connecting the wall panels P of the main body part H1 of the house, and an attached column having a bottom plate and a support piece connecting therebetween are used. Therefore, there is no need to replace the connecting fittings on the main body of the house, and remodeling of the main body of the house is minimized, making the construction more efficient and making it possible to live in the main body of the house while the addition is being carried out. Further, the attached columns can bear the load acting on the roof frame member R of the house attached part H2, and by eliminating the additional load on the house main body part H1, the reduction in the strength of the house can be reduced.
