Description

Technical Field

[0001] This utility model specifically relates to a prefabricated roof drainage structure, belonging to the field of building engineering technology. Background Technology

[0002] The roof drainage system is an important component of a building structure. Its main function is to collect and guide rainwater from the roof away from the building, preventing moisture from seeping into the walls or foundation, thus protecting the building from water damage. A key component is the drainage ditch, which is typically made of weather-resistant metal and assembled in sections. Installed along the underside of the eaves, it collects rainwater running off the roof. The joints between these sections are usually permanently connected using welding, which prevents adjustments after welding, resulting in low installation efficiency. Furthermore, the high temperatures generated during welding can cause thermal stress and deformation in the materials, affecting the stability of the drainage system.

[0003] Therefore, in order to address the shortcomings of existing technologies, a prefabricated roof drainage structure is proposed. Utility Model Content

The top of the beams and columns is a slope, and the beams and columns are connected to the slope of the roof. The eaves beam is provided at one end of the lowest point of the roof, and sealing plates are installed at both ends of the eaves beam. Bolt holes are provided on the sealing plates, and bolts connect the beams and columns to the eaves beam through the bolt holes.

The outer top of the drainage ditch is provided with the eaves cap, and the lower end of the eaves cap is connected to the fascia board.

[0007] Furthermore, connectors are provided between the multiple sets of drainage ditches, and the two ends of the connectors are provided with insertion interfaces. A sealing gasket is provided on the upper end of the inner surface of the insertion interface to prevent rainwater leakage.

[0008] Furthermore, the lower end of the connector is provided with a screw hole, the wall panel of the drainage ditch is inserted into the plug interface, and the screw is fastened through the screw hole.

[0009] Furthermore, the cross-section of the eaves beam is a rectangular square tube, and the surface of the eaves beam has square cutouts for positioning and fixing with the drainage ditch.

[0010] Furthermore, the eaves top includes a slanted buckle, a folded edge, and a groove. One end of the eaves top is provided with the slanted buckle, and the other end of the eaves top is provided with the folded edge. The upper edge of the folded edge is provided with a groove.

[0011] Furthermore, the upper end of the fascia board is provided with a slanted hook, which is connected to the slanted buckle, and the lower end of the fascia board is provided with a drip edge to prevent rainwater from flowing vertically from the fascia board to the eaves floor and side wall.
