Abstract

PURPOSE:To enable the size adjustment of a hip roof to be easily carried out at a construction site in constructing the hip roof in such a way that a plurality of roof panels are arranged in parallel to one another in the direction parallel to the ridge of the hip roof. CONSTITUTION:A hip roof is constructed by arranging a plurality of roof panels 2 in parallel to one another in the direction parallel to the ridge 1 of the hip roof. By this construction method triangular roof panels 2a located on both sides are first constructed toward the center side and then rectangular roof panels 2b located at the center portion are constructed at the final stage of construction. The final rectangular roof panel 2b is adjusted at a construction site so as to adjust construction error.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof construction method in which a plurality of roof panels are installed side by side.

0002

2. Description of the Related Art Conventionally, a roof construction method has been known in which a plurality of roof panels are installed side by side. A roof constructed by arranging roof panels 2 side by side is usually used to form a gable roof as shown in FIG. 4. In this case, the construction order was as shown by the arrow in FIG. 4, from one end in a direction parallel to the ridge 1 to the other end. In order to deal with construction errors that occur on-site, the dimensions of the roof panel 2 to be finally constructed are adjusted on-site (adjusted by re-creating the roof panel according to the dimensions on-site).

[Problem to be Solved by the Invention] However, in a hipped roof, in the direction perpendicular to the ridge 1, there is no construction error because the number of roof panels 2 used is small, but in the direction parallel to the ridge 1, the above-mentioned error occurs. When construction is carried out from one side end to the other side end (in the direction of the arrow in Fig. 5), due to construction errors due to the large number of roof panels 2 used, the other side end On the side, as shown by imaginary lines in FIG. 5, a trapezoidal roof panel 2c and a triangular roof panel 2a
does not match the designed line of the descending ridge 3, and therefore the dimensions of the trapezoidal roof panel 2c and the triangular roof panel 2a must be adjusted on site. There was a problem in that it took a lot of effort to recreate 2a on site.

[0004] The present invention was invented in view of the problems of the above-mentioned conventional examples, and its purpose is to provide a method for constructing a roof surface parallel to the ridge of a hipped roof. To provide a method for constructing a roof by which dimensions can be easily adjusted on site when constructing a plurality of roof panels in parallel in a direction.

[0005]

[Means for Solving the Problems] The roof construction method of the present invention is a method for constructing a roof surface parallel to the ridge 1 of a hipped roof, in which a plurality of roof panels 2 are arranged in a direction parallel to the ridge 1. When installing and constructing the roof panel, the construction is performed in order from the triangular roof panels 2a located on both sides to the center, and finally the rectangular roof panel 2b in the central portion. By adopting a configuration that
The object of the present invention has been achieved by solving the problems of the conventional example described above.

[0006]

[Operation] By starting with the triangular roof panels 2a located on both sides and working toward the center, and finally constructing the rectangular roof panel 2b in the center, construction errors at the site can be reduced. It is only necessary to modify the triangular roof panel 2b, and there is no need to modify the triangular roof panel 2a, etc. for dimensional adjustment on site.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the embodiments shown in FIGS. 1 to 3. As shown in FIG. 3, the roof panel 2 used in the present invention is composed of a triangular roof panel 2a, a trapezoidal roof panel 2c, and a rectangular roof panel 2b. The above-mentioned roof panel 2 is formed in advance at a factory, transported to the site, and suspended by a crane at the site, where it is erected and supported by ridge materials, purlins, eaves girders, etc. that form the framework of the building.

[0008] Thus, a hipped roof is formed by constructing the roof panels 2 described above, and in this case, the roof panels 2 are arranged as shown in FIG. Here, in order to construct a roof surface parallel to the ridge 1 of a hipped roof by arranging a plurality of roof panels 2 in parallel in the direction parallel to the ridge 1, as shown by the arrows in Fig. 1, Construction is carried out in order from the triangular roof panel 2a toward the center, and finally the rectangular roof panel 2b in the central portion. In this case, since the number of roof panels 2 used is large in the direction parallel to the ridge 1, there is a large error that occurs on site. 2b is modified on-site to adjust dimensions. Here, it is easier to modify the rectangular roof panel 2b for dimensional adjustment on site than to modify the triangular roof panel 2a and the trapezoidal roof panel 2c on site.

[0009] In the direction perpendicular to the ridge 1 of the hipped roof, since the number of roof panels 2 used is small, construction errors do not occur, or even if they occur, the errors are small, so construction can be performed without modification. . After constructing the roof panel 2 as described above, a roof board is placed on the top surface of the roof panel 2.

[0010] Note that the roof panel 2 may be covered with a roof board 5 in advance at a factory.

[0011]

[Effects of the Invention] As described above, in the method of constructing a roof surface parallel to the ridge of a hipped roof, a plurality of roof panels are installed in parallel in a direction parallel to the ridge. In doing so, construction is carried out in order from the triangular roof panels located on both sides to the center, and finally the rectangular roof panels in the center, so any construction errors on site will be corrected by reworking the rectangular roof panels in the center. Therefore, there is no need to modify the triangular roof panels or the like to adjust the dimensions on site, and the work of modifying the dimensions on site is simplified.
