Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a roof structure in which an eaves panel can be installed in a corner portion where the main roof and the additional roof intersect at a right angle with good workability and fit.

[Conventional technology]

A so-called prefabricated house, in which a house is formed by assembling members produced in a factory or the like, is often used. 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 is designed to have a total of two floors, for example, as shown in FIG. 10, to reduce costs, and as a result, the appearance tends to be poorly changed. 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.

For this diversification, for example, as shown in FIG.
It was proposed to increase the variety of appearance and widen the living space by providing a house additional part B integrally connected to the house main body A as shown by the chain line in the main body A of the second floor. .

In addition, in the conventional architectural concept, a house whose roof shape is changed by providing such a house addition part B is
Each time it is roofed using a roof set that matches its shape.

[Problems to be solved by the device]

However, as described above, in the case where the roof assembly is performed in accordance with the position of the house addition part each time, the projecting position of the house addition part is wide, so that it takes time and effort for designing, manufacturing, storing, etc. However, a change in the structure of the roof set tends to impair the characteristics of a standardized house, such as a structural change in each part of the main body of the house itself.

Therefore, the present inventor further covers the main body of the house with the main roof and the additional part of the house with the additional roof.
We have devised a roof structure that makes it possible to form a roof for the additional part of the house while minimizing changes in the structure of the main body of the house.

However, at this time, when using the roof panel of the standard length adopted in the standardized house, as shown in FIG. 11, the main body roof C is formed at the corner portion where the main roof C and the eave tip of the additional roof D are orthogonal to each other. The roof panel that forms the
There is a problem that it interferes with the additional wall body Va on the side of at the z position. Note that this is because the main body roof panel is manufactured in advance based on the reference module, and therefore cannot absorb the thickness of the additional wall body Va on the side.

The present invention is based on the fact that a notch portion is formed at the front eaves of the main roof panel, and the eaves panel is arranged by using a supporting material in the notch portion.
Further, it is possible to form the roof of the additional portion of the house while reducing the change in the structure of the house frame structure itself that receives the roof, and it is an object of the present invention to provide a roof structure that can be particularly suitably used in the standardized house described above.

[Means for Solving the Problems]

The present invention is directed to a sloping roof that covers a main body A of a house having a main body wall Wa provided with an opening and is formed using a main body roof panel CP and that has a main ridge X1 that is horizontal and is parallel to the main body wall Wa. A main body roof C, and an additional side wall body Vb extending outward at a right angle to the main body wall body Wa at one end of the opening, and an opening parallel to the main body wall body Wa at the outer end of the additional side wall body Vb. An additional roof D formed by using an additional roof panel DP, which covers the house additional portion B having an additional central wall body Vc extending outward and enclosing the opening portion in a U-shape; The roof panel CP has a main body eaves CN protruding from the main body wall Wa, and the additional side wall V from the opening.
By cutting up to the point where it breaks beyond b,
A cutout portion (11) having a continuous cutting edge on the main body wall Wa and a cutout edge extending outward at the cutout end is formed, and the cutout portion (11) and the additional side wall body Vb A horizontal rod (9), one end of which is fixed to the discontinuity edge and which extends in parallel and horizontally to the main body wall Wa.
1) and a supporting member (1) having an inclined rod (93) extending obliquely upward from the other end and fixed above the additional side wall body Vb.
The roof structure is characterized in that the inner end of a rectangular eaves panel (20) is fixed to the cutting edge and the eaves tip is supported by the horizontal rod (91) while the 9) is bridged.

[Action]

The main body part of the house is formed by using a main body roof panel. Therefore, the roof of the main body of the house can be formed almost in the same manner as when the additional part of the home is not provided.For example, when the main body of the house is a standardized house, its characteristics including the frame structure of the main body of the house receiving the roof can be improved. Can remain.

Further, the house main body part is provided with a house addition part so that the house can be changed to increase the variety and the living area. Moreover, the additional part of the house is covered with the additional roof formed by the additional roof panel. Therefore, an additional roof can be formed after the main roof is attached, which is convenient for construction and facilitates the assembly and configuration of the entire house.

Further, in the main body roof panel, the main body eaves protruding from the main body wall body are cut away from the opening provided in the main body wall body up to a discontinuity beyond the additional side wall body, thereby cutting off continuously on the main body wall body. A cutout portion is formed that has an edge and an interrupted edge that extends outward at the interrupted edge. Therefore, the interference between the main body roof panel and the additional side wall body can be prevented, and the main body roof of the main body part of the house adjacent to the additional house part can be formed well.

In addition, a supporting material is bridged over a portion of the cutout portion between the interrupted edge and the additional side wall body, and the eave tip of a rectangular eaves panel whose inner end is fixed to the cutting edge is horizontally attached to the supporting material. Since it is supported by the rod, the eaves panel can be installed conveniently and conveniently, and roof construction workability can be improved.
