Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof structure that facilitates roof construction of an additional part of the house that protrudes from the main part of the house.

[Conventional technology]

2. Description of the Related Art Houses constructed using the so-called prefabricated construction method, in which houses are constructed by assembling parts produced in factories, are often used. In addition, even in such prefabricated houses, it is desired to change the living area and diversify the appearance according to living preferences. On the other hand, among prefabricated houses, there is standardized housing, which was previously promoted as a national project by the Ministry of International Trade and Industry and the Ministry of Construction, with the main purpose of reducing housing costs and improving quality.

However, as shown in Figure 8, such standardized housing is designed to reduce costs by, for example, having two floors.
As a result, the appearance tends to be difficult to change, and it may not be possible to fully respond to the recent diversification of residents' tastes.

Therefore, even in such standardized housing, it is desired to diversify the appearance, etc., and even when diversifying, it is important to preserve the characteristics of standardized housing as much as possible.

In addition, for this diversification, for example, as shown in Fig. 8, a two-story house main body part A is provided with an additional house part B that is integrally connected to the house main body part A, as shown by a dashed line. In addition to increasing the diversification of the exterior appearance, it was also notable for expanding the living space.

In addition, in the conventional architectural concept, a house whose roof shape has been changed by providing such a house addition part B is roofed using a roof assembly that matches the shape each time.

[The problem that the idea aims to solve]

However, in this way, when assembling the roof according to the position of the additional part of the house each time, since the protruding position of the additional part of the house is diverse, it takes time and effort in designing, manufacturing, storing, etc. However, changes in the structure of the roof assembly tend to impair the characteristics of a standardized house, such as by causing structural changes to each part of the house itself.

The present invention is based on supporting the additional roof that covers the additional part of the house using the roof bracket on the additional wall of the additional part of the house, and the roof structure of the main part of the house, as well as the house frame structure itself that receives the roof. It became possible to form the roof of the additional part of the house while reducing structural changes.
The object of the present invention is to provide a roof structure that can be particularly suitably used in the above-mentioned standardized housing.

[Means to solve the problem]

The present invention covers a main body part A of a house having a main body wall Wa provided with an opening, is formed using a main body roof panel CP, and has a sloped roof having a main ridge part X1 that is horizontal and parallel to the main body wall Wa. The opening is surrounded in a U-shape using a main body roof C, an additional central wall Vc parallel to the main wall Wa of this house main body A, and additional side walls Va and Vb perpendicular to the main wall Wa. It consists of a passing roof D that covers an additional part B of the house having an additional wall V and is formed using an additional roof panel DP, and the additional roof panel DP has its base end extending from the upper surface of the main body roof panel CP to form the main body roof. A pair of inclined additional roof panels DP1 and DP2 on both sides of the ridge Y1 extending horizontally in the direction of inclination of the panel CP, and a triangular additional inclined roof panel DP3 disposed between these inclined additional panels DP1 and DP2 are used. , on the top surface of the wall panel forming the additional central wall Vc,
A roof support fitting 17C having a diagonal support piece 67 that supports the end of the triangular inclined additional roof panel DP3 on the eaves side is bolted to the upper surface of the wall panel forming the additional side walls Va and Vb, This roof structure is characterized in that roof brackets 17A and 17B having diagonal brackets 67 that support the ends of the additional inclined roof panels DP1 and DP2 on the eaves side are bolted to each other, respectively.

[Effect]

The main body of the house uses the main body roof panel to form the main body roof. Therefore, the roof of the house main body can be formed almost in the same way as if no additional house part was provided. For example, when the house main body is a standardized house, its characteristics including the frame of the house main body that receives the roof can remain.

In addition, an additional part of the house is protruded from the main part of the house.
Therefore, it is possible to change the house, increase its variety, and increase the living area. Moreover, the additional house part is formed by an additional roof panel using a pair of inclined additional roof panels on both sides of the ridge part whose base ends originate from the upper surface of the main roof panel, and a triangular inclined additional roof panel placed between them. covered with an additional roof. Therefore, an additional roof can be formed after the main roof is attached, making construction easier and helping to simplify the assembly and configuration of the entire house.

Furthermore, the edge of the eaves side of the additional sloped roof panel is
Since it is supported by a roof bracket that is bolted to the upper surface of a wall panel that forms an additional wall of the additional part of the house, the structure is simplified and workability can be improved.

[Effect of idea]

The main body of the house uses main body roof panels to form a main body roof consisting of a sloped roof. Therefore, the roof of the main body of the house can be formed almost in the same way as if no additional part of the house is provided, and even when the main body of the house is a standardized house, for example, deterioration of its characteristics can be prevented. Further, an additional house part is provided protruding from the main body of the house, so that the house can be changed to enhance its appearance and increase the living area. Moreover, the additional roof panel is constructed using a pair of additional sloped roof panels on both sides of the ridge part whose base ends extend from the upper surface of the main roof, and a triangular additional roof panel arranged between them. It is covered with an additional roof formed. Therefore, an additional roof can be formed after the main roof has been installed, which not only makes construction easier, but also reduces structural changes to the main body of the house due to the addition of additional parts to the house, which simplifies the assembly and configuration of the entire house. Helpful.

Additionally, the end of the additional roof panel on the eaves side is supported by the diagonal receiving piece of the roof bracket that is bolted onto the additional wall of the additional part of the house, making installation easier and improving workability. .
