Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a panel / metal fitting method for forming an outer wall of a house by joining wall panels using a connecting metal fitting, in order to provide an additional portion to the house. The present invention relates to an extension structure of a house, which is convenient for forming an attached foundation for receiving a wall panel 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 construction 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 in FIGS. By arranging the wall panels P on the upper and lower floors, a rectangular parallelepiped house main body H1 shown by solid lines in FIGS. 1 and 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. Further, such an extension is carried out when the house appendage H2 having the width of one wall panel P is added to the existing house main body H1, as shown by the one-dot chain line in FIG. As shown in the figure, there may be a case where a wide house appendage H2 extending over the lengths of the two wall panels P, P is added.

On the other hand, in the case of such an extension, it is possible to construct the extension while continuing to live in the existing house body H1.

Do not damage the interior of the house body H1 as much as possible.

It is possible to improve construction efficiency, prevent accidents such as fires, and enhance safety without using welding or fusing when building the building.

Etc. are desired.

In order to solve such a problem, the present inventor uses an attached connecting fitting for bolting to the upper connecting fitting without replacing the upper connecting fitting with respect to the upper end of the wall panel of the house body H2. I devised to fix it.

However, in supporting the lower end of the wall panel P of the house appendage H2, it is desirable to reduce the modification applied to the house main body H1 as much as possible.

However, conventionally, at the lower end of the wall panel P of the house appendage H2, the lower connecting fitting 2B is replaced, or
It was constructed by welding a new member for building addition.

[Problems to be Solved by the Invention]

However, replacement of the connecting metal fittings requires a large amount of work because of the attachment / detachment of the foundation and wall panel to which the connecting metal fittings are fixed, and the one in which members are provided by welding also makes site work difficult and inferior in safety. There is a problem.

The present invention is based on the fact that the side surface and the lower surface of the wall panel P are mounted and the bar arrangement is connected to the base mounting metal fitting through the base mounting metal fitting which is embedded in the auxiliary foundation connected to the outer surface of the foundation of the existing house main body H1. As a result, it is possible to increase the construction efficiency and improve the safety, and reduce the influence of the extension to the main body H1 of the house,
Also, the purpose is to provide an extension structure for a house that can form a strong attached foundation with good workability.

[Means for Solving the Problems]

The present invention relates to a main body of a house of a panel / metal fitting method that forms an outer wall of a house including a wall panel whose lower end is fixed by a connecting metal fitting on a foundation, and a wall arranged on an attached foundation extending from the outer surface of the foundation. A house extension structure for building a house appendage that includes a panel to form an outer wall, wherein the accessory foundation is a bar supporting metal fitting for fixing the bar panel lower end of the house accessory to a bar arrangement passing through the accessory foundation. Connected to the base mounting bracket of an attached anchor having a base mounting bracket that is hung from the panel support bracket and is supported by the anchor by an anchor pin that is fitted on the outer surface of the foundation of the main body of the house and is embedded in the accessory base. It is an extension structure of a new house.

[Action]

Attached anchor panel support bracket is the base B1 of the main body of the house H1
It is supported by an anchor pin fitted on the outer surface and is coupled to a base mounting bracket embedded in the attached base B2.

Therefore, it is possible to suppress the modification of the main body part H1 of the house to the foundation B1 to the minimum, streamline the additional construction and improve the safety, and it is possible to live in the main body part H1 during the additional construction. To do. Further, since the reinforcing bar of the attached foundation is connected to the basic mounting bracket, the labor of the reinforcing bar construction is reduced and the reinforcing accuracy of the reinforcing bar is increased and the basic strength is increased.

Body b6
And the vertical reinforcement portion of the inner reinforcement portion b5 is
The attached foundation B2 is formed by connecting the end of the with a wire or the like and then pouring concrete or the like using a formwork. A recess b7 having a bottom surface flush with the bottom surface of the cutout portion b1 is formed on the upper surface of the inner end of the accessory base B2. As a result, the panel support fitting 6 is exposed above the bottom surface thereof.

In this way, by using the panel support metal fitting 6 which is attached to the base mounting metal fitting 7 embedded in the attached base B2, modification of the base B1 of the house main body H1 is reduced. Therefore, the wall panel P of the main body H2 of the house can be obtained without extensive modification of the main body H1 of the house.
It is possible to attach the lower end of. Also the base mounting bracket 7
Since the reinforcement bar b3 is attached to the reinforcement bar b3, the reinforcement of the reinforcement bar b3 is good, and the attached anchor 8 is integrated to provide a strong attachment base B2.
Can be formed.

〔The invention's effect〕

Attached anchor panel support bracket is the base B1 of the main body of the house H1
It is supported by an anchor pin fitted on the outer surface and is coupled to a base mounting bracket embedded in the attached base B2.

Therefore, it is possible to suppress the modification of the main body part H1 of the house to the foundation B1 to the minimum, streamline the additional construction and improve the safety, and it is possible to live in the main body part H1 during the additional construction. To do. In addition, since the reinforcement bar of the attached foundation is connected to the foundation mounting bracket, the reinforcement efficiency and installation accuracy of the reinforcement are increased and the foundation strength is increased.
