Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a roof plate for a curved roof and a method of roofing the roof plate for a curved roof, which are used, for example, in a large building having a dome-shaped steel frame roof frame structure. It is something.

[Conventional technology]

The inventor of the present invention previously proposed a roofing board and a roofing construction method thereof in Japanese Patent Application Laid-Open No. 63-83360.

This roof board is made by narrowing down a long rectangular roof board material, forming bent parts at a plurality of locations at predetermined intervals in the left and right longitudinal directions, and providing engaging parts at the top, bottom, left, and right edges of the material. It is formed by narrowing one of the upper and lower edges and bending it into an arc shape.

In addition, the roofing construction method uses the above-mentioned roofing boards,
A basic structure having a plurality of roof plates with different arcuate curvatures in the upper and lower stages, and a plurality of rows of vertical frame members, and a plurality of upper and lower horizontal frame members that connect and surround these vertical frame members. Roofing is done by fixing the rafters on each row of rafters fixed at predetermined intervals via hangers, and then engaging and connecting adjacent roof panels to install horizontal roofing.

[Problem to be solved by the invention]

However, the roofing board proposed earlier by the inventor is made by narrowing down a long rectangular roofing material in advance to fit the curved surface of the roof to be roofed, forming bends at multiple locations in the longitudinal direction, It is difficult to narrow down and bend into an arc shape, and in the roof shingle construction method, the shape of the bent part of the roof shingle and the curvature at which it is bent into an arc shape are different for the upper and lower roof shingles. Therefore, these processes were troublesome.

Furthermore, the above-mentioned roof panels have little flexibility in the upper and lower roof panels, and for roofs such as dome-shaped roofs that have different shapes and sizes, it is necessary to manufacture roof panels with different dimensions and shapes each time. There were problems in that the boards were expensive and it took a long time from ordering to completion of construction.

The present invention solves the above-mentioned problems and provides a roof board for curved roofs that is relatively easy to manufacture, has a large degree of freedom, and can be used on multiple roofs of different shapes and sizes, and is inexpensive and easy to use. The purpose of the present invention is to provide a roofing construction method for curved roof shingles that can shorten the period from notation to completion of construction.

[Means to solve the problem]

The roof board for a curved roof according to the first invention includes a main roof board in which engaging parts are formed on the upper, left, and right sides of the rectangular board surface, and engaging parts that are formed on the upper, left, and right sides of the ladder-shaped board surface. and an auxiliary roof plate interposed between the main roof plates that are laterally adjacent to each other.

In addition, the second invention has a main roof plate in which engaging parts are formed on the top, left, and right sides of the rectangular plate surface, and on the ladder-shaped plate surface,
A curved roof plate consisting of auxiliary roof plates with engaging parts formed on the left and right sides is used, and the main roof plate and the auxiliary roof plate are arranged alternately in the horizontal direction, and the adjacent main roof plate and auxiliary roof plate are arranged alternately in the horizontal direction. The plates are engaged and connected to form a polygonal shape approximating an annular shape, and the inclination angles of the opposing edges of the horizontally adjacent main roof plates in each of the upper and lower levels are different from each other in each level to form multiple rows of vertical frame members. , the main roof board is fixed via hangers on each row of rafters fixed at a predetermined interval on a basic structure having horizontal frame members of multiple upper and lower stages connecting and surrounding these vertical frame members. This invention relates to a roofing construction method for curved roof shingles, which is characterized by engaging and combining vertically adjacent main roof shingles and auxiliary roof shingles.

[Effect]

The first invention consists of a main roof plate with a rectangular plate surface and an auxiliary roof plate with a trapezoidal plate surface, so these main roof plates and auxiliary roof plates can be easily obtained, and the upper and lower parts of the same dome-shaped roof etc. To horizontally roof multiple levels, use main and auxiliary roof plates of the same shape and size, and adjust the inclination angle of the opposite edges of the horizontally adjacent main roof plates in the lower and upper sections. A curved surface can be formed by simply changing the .

Furthermore, when horizontally roofing multiple curved roofs with different curved shapes and sizes, main roof panels and auxiliary roof panels of the same shape and size can be used, and auxiliary roof panels can be used as needed. Even if the roof panels may be different, the degree of freedom of the roof panels, that is, the range of use is wide, and by stocking standard main roof panels and auxiliary roof panels in advance, it is possible to provide roof panels for curved roofs at low cost. I can do it.

In addition, the method for roofing roof shingles for curved roofs according to the second invention uses main roof shingles and auxiliary roof shingles of the same shape to horizontally roof multiple upper and lower levels of a dome-shaped roof, etc. The angle of inclination of the opposite edges of the main roof panels adjacent to each other can be varied, and one type of roof panel for curved roofs can be used in a wide range of applications. , it is possible to easily and inexpensively install a curved roof, and furthermore, the period from the initial designation to the completion of construction can be shortened.
