Description

Technical Field

[0001] The utility model relates to the technical field of steel structure buildings, in particular to a waterproof structure for a ridge node of a steel structure slope roof. Background Art

[0002] The ridge refers to the intersection line between the top of the relative slope of the roof or the two opposite sides, and the ridge node of the steel structure is used in steel structure buildings. The material of the ridge node of the steel structure is steel. Steel structure buildings are usually factory buildings and other buildings. They are constructed of steel structure supports, surface colored steel and a series of accessories. The ridge node of the steel structure is set at the intersection of the roof slope of the steel structure building. The left and right sides of the ridge node of the steel structure are provided with a sloping roof composed of colored steel and steel frame. The ridge node of the steel structure and the slope of the roof together constitute the roof, which protects the items inside the steel structure building from wind and rain.

[0003] According to a steel structure waterproof and thermal insulation ridge node disclosed in Chinese patent publication number CN 219931425 U, it is proposed that the ridge cover plate on the existing steel structure waterproof and thermal insulation ridge node is easily subjected to a certain pressure, thereby deforming, thereby causing the rivets between the ridge cover plate and the roof panel to fall off and tear. When the patent uses the supporting member, since the lower connecting plate is connected to the upper part of the insulation layer, the middle plate is connected to the upper middle part of the lower connecting plate, and the reinforcing plate is connected to the upper part of the middle plate and fits with the lower part of the ridge cover plate, the middle plate can play a better role in supporting the reinforcing plate. At this time, the reinforcing plate can support the middle part of the ridge cover plate, thereby preventing the ridge cover plate from deforming when subjected to external pressure, thereby improving the stability of the ridge cover plate. However, the device has a complex structure in actual use, and each connection part is affected by gravity, which will cause the screws to deform, causing looseness between the parts, thereby causing water leakage.

[0004] To this end, we proposed a steel structure slope roof ridge node waterproof structure to solve the problems of complex structure, unstable connection parts, and easy gaps that lead to leakage. Utility Model Content

[0012] Preferably, a filter screen is fixedly connected to the middle of the drainage trough, and a valve body is installed on the drainage pipe.

[0013] Preferably, a connecting pipe is fixedly connected between the drainage grooves, and a guide plate is fixedly connected to the middle of the upper end of the drainage groove.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, the utility model supports the bracket by arranging purlins on the steel beam.
