Description

Technical Field

[0001] This utility model relates to a leak-proof structure for gutters on sloping roofs. Background Technology

[0002] Gutters are used to collect rainwater from the roof and guide it to the downpipe to prevent water accumulation and leakage. In heavy rain or storms, some factory buildings with long sloping roofs often experience problems due to the accumulation of rainwater. This can cause the drainage efficiency to be unable to keep up with the speed of rainwater accumulation, leading to water accumulation, deformation, and collapse of the gutters. Ultimately, this can result in rainwater eroding the base of the walls and causing leakage. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof structure for gutters on sloping roofs. By setting a central gutter on the sloping roof, rainwater is intercepted, and the external gutter is prevented from deforming due to excessive water accumulation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof structure for a pitched roof gutter, comprising a first pitched roof, a second pitched roof, a cantilever beam, a central gutter, and an outer gutter. The first pitched roof and the second pitched roof are in the same inclination direction. The central gutter is located between the first pitched roof and the second pitched roof. The outer gutter is located on the outer side of the second pitched roof. Multiple cantilever beams are arranged along the length of the first pitched roof. Several support seats are provided on the cantilever beams for fixing and supporting the first pitched roof and the second pitched roof, respectively. A downpipe is provided on the central gutter. Support components for supporting the central gutter are provided on both sides of the cantilever beams corresponding to the positions of the central gutter.

[0005] As a further improvement of this utility model, the support assembly includes a support plate fixedly connected to the cantilever beam and a pair of bracket seats arranged on both sides of the support plate. One side of the bracket seat is fixedly connected to the support plate, and the other side of the bracket seat abuts against the bottom of the gutter. The support plate is provided with a clamping assembly for fixing the downpipe at the position corresponding to the downpipe.

[0006] As a further improvement of this utility model, the clamping assembly includes an installation part and a clamping part. The installation part is provided with an installation groove for the support plate to extend into. The support plate is provided with a through groove corresponding to the installation groove. The installation part is installed on the support plate and is provided with a plurality of through holes for installing locking components corresponding to the through groove. The clamping part is provided with a plurality of clamps arranged along the height direction of the downpipe. The clamps are clamped on the outer surface of the downpipe.

[0007] As a further improvement of this utility model, the side panels on both sides of the central gutter extend to the bottom of the first and second sloping roofs. Sealing strips are provided between the side panels and both the first and second sloping roofs. A pair of fixing seats for securing the central gutter are provided on the cantilever beam. One side of each fixing seat is fixedly connected to the cantilever beam, and the other side of the fixing seat is locked to the side panels, sealing strips, and either the first or second sloping roof using locking devices.

[0008] As a further improvement of this utility model, a baffle for limiting the position is provided on one side of the fixed base corresponding to the side plate.

[0009] The beneficial effects of this utility model are: by setting up a central gutter between sloping roofs at the same angle of inclination to intercept water flow, the phenomenon of external gutters collapsing due to excessive weight caused by rainwater accumulation during heavy rain is effectively reduced.

The first pitched roof 1 and the second pitched roof 2 are in the same direction of inclination. The central gutter 4 is located between the first pitched roof 1 and the second pitched roof 2, and the outer gutter 5 is located on the outside of the second pitched roof 2. The central gutter 4, located between the first pitched roof 1 and the second pitched roof 2, can intercept rainwater on the pitched roof, allowing rainwater to drain in stages. This effectively reduces the risk of the outer gutter 5 collapsing due to excessive weight caused by insufficient drainage efficiency caused by excessive rainwater accumulation. The cantilever beam 3 runs along the first pitched roof... Multiple supports are arranged along the length of the cantilever beam 3. Several support seats 6 are provided on the cantilever beam 3 for fixing and supporting the first sloping roof 1 and the second sloping roof 2 respectively. One side of the support seat 6 is fixedly connected to the first sloping roof 1 and the second sloping roof 2, and the other side of the support seat 6 is fixedly connected to the cantilever beam 3. Multiple support seats 6 are provided so that the first sloping roof 1 and the second sloping roof 2 can be reliably fixed on the cantilever beam 3. A downpipe 7 is provided on the central gutter 4. Support components 8 for supporting the central gutter 4 are provided on both sides of the cantilever beam 3 at the positions corresponding to the central gutter 4. The support components 8 on both sides of the cantilever beam 3 increase the support area of ​​the central gutter 4 and improve the stability of the installation of the central gutter 4.
