Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plastic roof that is suitably used as a roof for carports, bus stations, corridors, benches, stadiums, and the like.

[0002]

[Prior art]

 Conventionally, this type of plastic roof has a plurality of pillars to which beams are respectively attached, a plurality of support members are laid on these beams, and a plurality of transparent plastics are mounted on these support members. It is known that roofing boards such as boards are stretched over.

However, in the above-mentioned conventional roof, since the roof plate is mounted on the beam via the support member, the weight of the roof is increased by the amount necessary for the support member and the roof is supported. For this reason, greater support strength is required for the beams and columns, but since the receiving material is intervening, the transmitted light is blocked by it, making it feel dark, and the roof looks thick, so the appearance is neat. It wasn't.

Further, since a gutter of aluminum or vinyl chloride resin is separately provided on the outer edge portion of the roof plate, it takes time to assemble, the cost is high, and the roof plate and the gutter of the roof plate are long-term use. There was a risk of water leaking from the joints, and there was also the problem of corrosion of the gutter bracket used to connect the roof panel to the gutter.

[0005]

[Problems to be solved by the device]

 The present invention has been made in view of these circumstances, and has a small number of supporting members for attaching a roof plate, which makes it possible to reduce the weight of the roof and increase the transmitted light to give a bright feeling. While the roof looks thin and wide, which is aesthetically pleasing, the space on the upper surface of the beam where dust adheres can be eliminated, and the roof plate part and the gutter part are integrally molded to prevent water leakage. The objective is to provide a plastic roof that can be reliably prevented, which can greatly simplify on-site construction and greatly reduce costs overall.

[0006]

[Means for Solving the Problems]

 This purpose consists of a roof plate part and a gutter part, and these roof plate part and gutter part are formed by integral molding of one plastic plate, and a water gradient is formed in the roof plate part The solution is to install one or more plastic roof units with gutters on the side so that the gutters communicate with each other and attach them to the beam.

[0007]

[Action]

 The plastic roof of the present invention uses the plastic roof unit in which the roof plate part and the gutter part are formed by integrally molding one plastic plate, and thus the metal receiving material for mounting the roof plate is small. No metal fittings for gutters are required.
