Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a roof structure with a skylight.

[Prior Art] A skylight has the advantage of improving indoor lighting, and a roof structure equipped with a skylight has been proposed, for example, as described in Japanese Utility Model Publication No. 59-22827. This roof structure has a dome portion of a skylight projecting from the center of the roof surface made of corrugated roofing material, and the roof surface around the skylight is all set to the same slope.

Drainage grooves are formed in the abutting parts of each roof surface that abut the dome part of the skylight on the dome side and the water bottom side, extending in a direction perpendicular to the corrugations and communicating with the corrugated recesses of the adjacent roofing material. There is.

As a result, rainwater that flows down from the water side along the slope of the corrugated roofing material on the roof surface and collides with the dome is distributed along the drainage ditch, and is distributed to the roof surface located on the water side of the dome. Rainwater is prevented from accumulating in the four parts of the corrugation.

[Problems to be Solved by the Invention] However, the formation of such drainage channels complicates the structure of the roof and increases the construction cost of the skylight. In addition, water along the slope and rainwater rippling from the H side strongly collide with the dome, and there is a risk that rainwater may enter the room through the seal between the dome and the roof surface. In addition, rainwater is distributed through drainage ditches.

Rainwater flowing on the side of the skylight in the direction along the corrugated roof material joins together on the side of the skylight, and a large amount of rainwater may infiltrate into the room from the side seal portion of the skylight.

An object of the present invention is to smoothly manage the flow of rainwater around a skylight while simplifying the structure of the roof.

- [Means for Solving the Problems] In order to achieve the above object, the present invention provides a roof surface made of corrugated sheet roofing material with a dome portion of a skylight projecting from the roof surface, and a dome portion of a skylight is provided in a direction along the corrugated shape of the roofing material. In a roof structure with a skylight in which the slopes of each roof surface laid on both sides of the skylight are set in the same direction with respect to the horizontal plane, the roof is laid on one side of the skylight in the direction perpendicular to the corrugation of the roofing material. The slope of the roof surface laid on the other side of the skylight with respect to the horizontal plane is reversed with the skylight facing above the water.

[Operation] According to the present invention, the slopes of the roof surfaces laid on both sides of the skylight in the direction along the waveform of the roofing material are set in the same direction with respect to the horizontal plane, and the slope is perpendicular to the waveform of the roofing material. The slope that the roof surface laid on one side of the skylight makes with respect to the horizontal plane in the direction of As a result, rainwater does not accumulate in the abutment areas between the dome part of the skylight and each roof surface, and the rainwater is guided by the corrugated recesses extending downward along the slope of each roof surface and smoothly flows toward the eaves. It happens. Therefore, it is possible to smoothly manage the flow of rainwater around the skylight while simplifying the structure of the roof.
