Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a roof structure that can improve the workability of the roof by forming rafters into a framework.

[Conventional technology]

In the case of a sloping roof, the roofing board a forming the roof surface is the fifth
As shown in the figure, multiple rafters extend from the ridge to the eaves.
-...Mounted on top. In addition, the rafters are supported by horizontal members C, such as purlins and ridgepoles, which extend parallel to the girders.

[Problem to be solved by the invention]

While such a rafter is inclined at an inclination angle equal to the slope of the roof a, the horizontal members C are formed using square timbers with high strength or square timbers made of steel in order to bear the acting force applied to the roof Ila. Therefore, the upper surface d of the main building C is formed as a horizontal surface. Therefore, as shown in Fig. 6, for example, the rafters were connected using a connecting fitting f having an inclined piece e inclined at an angle equal to the slope of the roof a, and therefore it took time and effort to connect the two members. Also, the cost increases.

Furthermore, in order to increase the rigidity of the roof, a place g is attached to the rafter as shown in FIG. Since such a place g is stretched when assembling members on-site, there are problems in that it requires time and effort to construct and prolongs the construction period.

The present invention improves on-site construction workability by providing the horizontal members with diagonal pieces that slope at an angle approximately equal to the slope of the roof, and forming the rafters as rigid roof panels. The aim is to provide a roof structure that can also increase the rigidity of the roof.

[Issues to solve the problem]

In order to solve the above problem, the roof structure of the present invention includes:
At the upper end of the horizontal members that support the sloped roof and are horizontally arranged at different heights in parallel, a sloped piece whose eaves side slopes downward at an angle of inclination equal to that of the sloped roof is formed. A roof panel having a framework in which vertical members are connected by horizontal members is placed over the diagonal pieces of the horizontal members, and the horizontal members and the roof panel are bolted together.

[Effect]

Since the horizontal members have diagonal pieces that are inclined at an angle substantially equal to the slope of the pitched roof, the roof panels can be attached only to the horizontal members without using separate connecting fittings.

Since the vertical members are framed together with the equipment to form the roof panel, the roof panel has rigidity without the need for reinforcement using places.

Therefore, roof foundation work such as installing rafters on site is simplified, and construction efficiency can be increased. Furthermore, since roof panels can be produced in factories, they can be manufactured efficiently and costs can be significantly reduced.
