Description

[Detailed Description of the Invention] [Industrial field of application] The present invention enables positioning of an additional roof panel that covers an additional part of a house adjacent to the main body of the house by temporarily placing the roof panel. The present invention relates to a roof structure that facilitates roof construction and streamlines roof construction.

[Conventional technology]

Houses of the panel construction method in which walls, floors, roofs, etc. are formed using panels are often used.

In addition, among the houses having such a panel construction method, there is a standardized house which was promoted as a national project by the Ministry of International Trade and Industry and the Ministry of Construction mainly for the purpose of cost reduction and improvement of quality of the house. However, such a standardized house, for example, as shown in FIG. 11, has a total second floor house, for example, to reduce costs,
As a result, the change in appearance tends to be poor,
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.

As described above, in the case where the roof assembly is performed according to the position of the house addition part B each time, since the projecting position of the house addition part B is diverse, it takes a lot of time to design, manufacture, store, 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 inventors can suppress the change in the roof structure of the house main body A by covering the main body A of the house with the main roof and the additional part B of the house with the additional roof, and can improve the characteristics as a standardized house. We have devised a roof structure that can diversify the appearance of the house while maintaining it.

However, since the additional roof panel forming such an additional roof is attached after the construction of the main body roof, it is necessary to improve the efficiency of installation construction of the additional roof panel. Furthermore, in order to improve the construction efficiency, it is necessary to temporarily place the additional roof panel suspended by a crane, etc., to shorten the usage time of the crane and to make the panel alignment efficient. Therefore, it is desirable to complete the construction of the additional roof together with the main roof, preferably at the time of the upper building.

[Problems to be solved by the device]

In order to satisfy the above-mentioned request, the applicant has been instructed by the Japanese Utility Model Publication No. 1-16861.
As shown in FIG. 12 by No. 5, two inclined additional roof panels b and c are arranged on both sides of the ridge a of the additional roof. One inclined additional roof panel b is added. The structure which forms the temporary stand which supports the roof panel c was proposed. However, as shown in FIG. 13, in the case of the above-mentioned No. 1-168615, when connecting the other inclined additional roof panel c, an operator rides on the one inclined additional roof panel b provided with the connection fitting d. Since the inclined additional roof panel b is fixed only to the edge e at the time of working, the strength of the panel is insufficient and the work is dangerous.

The present invention is based on the use of a connecting fitting in which a hanging piece is provided on at least one of a pair of blades that respectively connects a pair of inclined additional roof panels with a hanging piece that abuts the upper surface of the main body roof panel below the inclined additional roof panel. An object of the present invention is to provide a roof structure capable of temporarily placing the inclined additional roof panel, improving the safety at the time of assembling, facilitating alignment, and shortening the use time of the crane.

[Means for Solving the Problems]
