Description

Description: TECHNICAL FIELD The present invention relates to a structure of a house that can increase the mounting strength of an additional wall of an additional part of the house protruding from the main body of the house and prevent the warp of the additional wall.

[Conventional technology]

A so-called Parehab method is often used to form a house by assembling members produced in a factory or the like. Also in such a prefabricated house, it is desired to change the living area and diversify the appearance according to the preference of the resident. On the other hand, prefabricated houses include standardized houses that were previously promoted by the Ministry of International Trade and Industry and the Ministry of Construction as national projects, mainly for the purpose of cost reduction and quality improvement of houses.

However, such a standardized house, for example, as shown in FIG. 9, has a total second floor house, for example, to reduce costs, and as a result, the appearance tends to change poorly. In recent years, it may not be possible to sufficiently cope with the diversification of the tastes of residents.

Therefore, even in such a standardized house, it is desired to diversify the appearance and the like, and it is important to retain the characteristics of the standardized house as much as possible even when diversifying.

Further, for this diversification, for example, as shown in FIG. 9, by providing a house addition part B integrally connected to the house body part A as shown by a chain line in the house body part A on the second floor, The idea was to increase the versatility of and to expand the living space.

[Problems to be Solved by the Invention]

However, such a house addition section B is
Therefore, it is necessary to remove the main body wall portion of the house main body portion A at the portion of the house addition portion B from the house main body portion A. At this time, when the main body wall is removed carelessly, the strength of the house main body portion A itself tends to decrease. Further, the house addition section B is attached to the house main body section A set as an independent house in advance.
When the main body wall of the main body A of the house facing the two additional walls is removed, the strength and rigidity of the additional main body may be inferior, and the additional wall tends to be deformed inward and outward. When it does, it tends to deform.

Further, in the place where the main body wall is removed, it is difficult to firmly support the eaves part of the main body roof panel forming the roof of the house main body A, and improvement thereof has been desired.

The present invention is based on the fact that a joint beam provided with a fixing bracket for fixing the main body roof panel is bridged between the beam material of the main body of the house and the additional wall body of the additional house, and the additional wall body is warped and deformed. The purpose of the present invention is to provide a structure of a house in which the strength of the main body of the house can be prevented from being reduced without making a large change to the main body of the house and the eaves of the main roof panel can be firmly supported.

[Means for Solving the Problems]

The present invention is a house having a main body roof C which uses a main body roof panel CP and is a sloping roof provided with a horizontal main ridge portion X1, and has the main ridge portion X1 with many openings in a parallel main body wall Wa. Main body A and additional wall parallel to the opening of the main body A of the house
Vc, and an additional wall that joins both ends of the Vc with both ends of the opening
The house main body A has a beam H that is bridged in a straight line with the main body wall Wa above the opening, and the house additional part B is The receiving beam (61C) is arranged at the upper end of the additional wall body Vc, and the additional wall body Vc is provided between the beam member H and the additional wall body Vc at one end of the elongated base body (37). A bottom piece (a mounting plate (39) fixed to the receiving beam (61C) is provided on the upper surface, and the other end is interposed between the adjacent main body roof panels CP and fixed to the upper surface of the beam H ( 43) and a joint beam (12) comprising a fixing metal fitting (40) rising from both end edges and supporting pieces (44) (44) for fixing the main body roof panel CP. It is the structure of the house.

[Action]

By adding a joint amount between the beam material bridged over the opening provided in the main body of the house and the additional wall parallel to the opening of the additional part of the house, the additional house is added. The additional wall of the section is prevented from warping and the mounting accuracy is improved. Further, by increasing the rigidity and strength of the additional wall body, deformation due to wind pressure or the like is prevented. Further, the beam material reduces deterioration of the rigidity of the main body of the house. Therefore, even when the main body of the house is a standardized house, the structure of the house can be configured without largely changing the specifications.

Furthermore, since the main body roof panel forming the main body roof of the house main body is fixed to the supporting piece of the fixing metal fitting provided on the joint beam, the main body roof panel arranged above the opening can be firmly supported, It is possible to prevent a decrease in the strength of the main body roof due to the provision of the additional portion.
