While a larger supporting strength is required for the pillar 1 and the pillar 1, since the beam 3 is interposed, the transmitted light is blocked by that amount, and the roof looks thick, and therefore the appearance is not neat. Since a space is formed between the upper surface of the girder 2 and the roof plate 4, there is a problem that dust or the like tends to adhere to the upper surface of the girder 2. Further, since the sash or caulking packing material is used for the mounting portion and the draining portion of the roof plate 4, there is a problem that the cost is high and there is a risk of water leakage when used for a long period of time. Furthermore, since the gutter 5 made of aluminum or vinyl chloride resin and the water collector 6 for the gutter are separately provided on the outer edge portion of the roof plate 4, it takes a lot of time and effort to assemble, and the cost is high.
Roof panel 4, gutter 5 or gutter water collector 6 after long-term use
There is a risk of water leakage from the connection part of.

The present invention has been made in view of the above circumstances. An object of the present invention is to significantly improve the mounting strength by mounting a roof plate so as to enclose a beam. It is not necessary to use crossbeams for attaching the roof plate, the weight of the roof can be reduced, the transmitted light increases and it feels bright, and the roof looks thin and wide, and is therefore aesthetically pleasing, It is possible to eliminate the space on the upper surface of the beam where dust, etc. adhere.
By forming the water collector and the drainage part integrally with the roof plate, it is possible to reliably prevent the risk of water leakage,
It is to provide a roof structure that can significantly reduce the cost as a whole.

[0005]

In order to achieve the above object, the present invention provides a roof structure in which a beam is attached to the upper part of a column, and a roof plate is attached to the beam. The hugging projections that wrap around the upper surface and the side surface of the beam are integrally formed at the edge portion facing the above, and the water collecting groove portion is integrally formed at the outer edge portion of the roof plate.

[0006]

In the structure of the roof of the present invention, the mounting strength is improved by mounting the roof plate so as to wrap the upper surface and the side surface of the beam by the hugging protrusion formed integrally with the roof plate. At the same time, the rainwater collected on the roof plate is collected and discharged to the ground by the water collecting groove formed integrally with the roof plate.
