Description

Description: TECHNICAL FIELD The present invention relates to a roof structure capable of efficiently mounting an additional roof panel that covers an additional house portion adjacent to a main body of a house.

[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 is, for example, as shown in FIG. 10, designed to be a house on the second floor so as 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.

[Problems to be Solved by the Invention]

However, as described above, in the case where the roof assembly is performed in accordance with the position of the house addition portion B each time, the roof addition portion B is
Since the projecting positions of are various, designing, manufacturing,
It takes a lot of time to store, and changes in the structure of the roof structure tend to impair the characteristics of a standardized house, such as the structural changes of 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 house main body A with the main roof and the house additional part B with the additional roof, and have 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.

INDUSTRIAL APPLICABILITY The present invention basically supports the base end side of the tilted additional roof panel by using a bundle fitting mounted on the upper surface of the main body roof panel, and the tilted additional roof panel can be temporarily placed, and the alignment is easy. In addition, the purpose of the present invention is to provide a roof structure which can shorten the usage time of the crane and can meet the above requirements.

[Means for Solving the Problems]

The present invention uses a main body roof panel CP that covers the main body portion A of the house and a main body roof C that is an inclined roof having a horizontal main ridge portion X1, and one main body wall that sandwiches one corner portion of the main body portion A of the house. An additional roof D formed by using an additional roof panel DP that covers a house additional portion B having an additional wall body V surrounding the opening formed in the body Wa from the corner portion in a U-shape, and the main body roof panel CP In the main body eaves CN protruding from the main body wall Wa of the house main body A, a notch (11) is provided at the opening to cut off the main body eaves CN, and the additional roof panel DP is the main roof. A pair of inclined additional roof panels D on both sides of the ridge Y1 that extend from the upper surface of the panel CP and extend horizontally in the inclination direction of the main roof panel CP.
A bottom plate (53) that includes P1 and DP2 and is placed on the upper surface of the main roof panel CP below the inclined additional roof panels DP1 and DP2 and at the base end side of the ridge Y1; A bundle fitting (16) including a bundle (51) standing upright and a holding plate (52) provided at the upper end of the bundle (51) and having the same inclination as the inclination of both flows of the inclined additional roof panels DP1 and DP2. The ridged additional roof panels DP1 and DP2 are connected by fixing the ridge Y1 of the pair of inclined additional roof panels DP1 and DP2 and the base end side to the upper surface of the holding plate (52). It is a roof structure.

[Action]

The house body is covered with a body roof using a 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, the characteristic can be left. 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 house additional part is formed by an additional roof formed by using an additional roof panel including a pair of inclined additional roof panels on both sides of the ridge that originates from the upper surface of the main body roof panel and extends horizontally in the inclination direction of the main body roof panel. To be covered. Therefore, an additional roof can be formed after the main roof is attached, which is convenient for construction and can reduce the structural change of the main body of the house due to the addition of the additional house, which is useful for assembling and constructing the entire house. .

In addition, the bundle fittings placed on the upper surface of the main body roof panel and on the base end side of the ridge portion are provided with a holding plate at the upper end thereof having the same inclination as the inclination of both flows of the inclined additional roof panel. Therefore, although the sloping additional roof panel forms a double-flow roof, its ridge can be temporarily placed by the holding plate. Also, for example, even when it is hung on a crane or the like, the hanging rope can be removed by temporary placement, the usage time of the crane can be shortened, and the efficiency of construction can be improved.
