Description

Terminal drop long gutter structure

technical field

The utility model relates to a roof drainage structure, in particular to a terminal drop long gutter structure.

Background technique

The gutter refers to the concave part between the two crotches of the roof of the building. When it rains, the rainwater is concentrated in the concave part and then drained by the rainwater pipe. The ditch where the rainwater is collected is called the gutter, which is an important part of the roof drainage system. Traditional gutters are mostly made of white iron sheet, asbestos, reinforced concrete prefabricated trough plates and other materials. In recent years, they have been developed to be made of PVC, aluminum alloy and other materials. The gutter is also connected to other components of the drainage system. Several rainwater holes are connected under the gutter, the rainwater bucket is connected to the rainwater pipe, and the rainwater pipe is connected to the discharge pipe to discharge the rainwater into the ditch or sewer.

In the traditional large-scale roof drainage system, the distance between the rainwater holes is less than or equal to 24 meters, and many rainwater horizontal branch pipes are suspended under the roof. After the holes are opened on the board, a small-diameter dn outer diameter is less than or equal to 90 mm polyethylene plastic water supply pipes, and the installation workers fill the holes. It is complicated and troublesome, the opening is easy to deform and leak, there are many metal components for the support and hanger, the maintenance is difficult, and the production cost is high.

Judging from the existing large-scale roof drainage gutters, there are disadvantages such as complex drainage system, many and chaotic pipelines, and many gutter openings, which make maintenance difficult.

Contents of the invention

The purpose of this utility model is to overcome the shortcomings of the existing roof gutter drainage system and provide a gutter drainage system with large drainage, convenient manufacture and installation, simple management and maintenance, low cost, and suitable for roofs in areas with heavy rainfall. It is especially suitable for the roof structure of large factory buildings and warehouses.

In order to achieve the above object, the technical scheme adopted in the present invention is as follows:

A long gutter structure with terminal drop. The gutter is set at the span or edge of the building roof and fixed above the gable. Expansion joints are set in the middle of the gutter to adapt to changes in the length of the gutter caused by temperature changes. The middle of the gutter There is an inclined slope on both sides, which is conducive to the flow of rainwater to both sides. The outer end of the gutter is suspended from the roof and gable. It leads to the ditch around the building, and the entire roof gutter drainage system is set outside the building's outer wall as a whole.

The material for making the gutter can be cement concrete, PVC, aluminum alloy or galvanized iron sheet.

The outer end of the gutter is provided with an overflow hole. When the rainwater bucket or the rainwater pipe is blocked, the rainwater will be discharged from the overflow hole. Connect the overflow drain pipe to other downpipes, and set a grid inside the overflow hole. The grid can be in various forms such as a spherical grille, a cylindrical grille, etc. The grid can isolate debris and prevent debris from overflowing. Orifice blocked.

The rain bucket is in the shape of a spherical net cover, which can effectively block the sundries entering the gutter outside the net cover and prevent them from entering the water drop.

A short trumpet pipe is arranged between the rainwater bucket and the rainwater pipe to make the water flowing into the rainwater pipe smoother.

The rainwater pipe is a socket-type pipe, which is convenient for installation and construction, and convenient for disassembly and replacement.

The utility model has the advantages of:

1. The utility model does not have any problem of opening holes in the gutter, so there is no hidden danger of easy deformation and water leakage. The gutter manufacturing and installation process is simple and simple. There are temperature change expansion joints, and there will be no gutter deformation under the condition of large temperature range changes. The terminal of the gutter cantilever to the outside of the gable, and the terminal is provided with a water outlet. The rainwater riser is exposed outside the gable, which does not occupy the interior space of the building. The rainwater riser adopts a large-diameter socket water supply pipe, which is easy to disassemble.

2. The outer end of the gutter is provided with an overflow hole. When the rainwater bucket or the rainwater pipe is blocked, the rainwater will be discharged from the overflow hole to prevent excessive water accumulation in the gutter-shaped plate from overflowing from the middle part, and the overflow hole is externally connected. The overflow drain pipe can concentrate the overflowing water into a water column to flow down, or the overflow drain pipe can be connected to other downpipes. A grid is set inside the overflow hole, and the grid can isolate the sundries and prevent the sundries from falling Overflow hole blocked.

3. A short trumpet pipe is set between the rainwater bucket and the rainwater pipe to make the water flow into the rainwater pipe smoother.

4. The rainwater bucket is in the shape of a spherical net cover, which can effectively block the sundries entering the gutter from the net cover and prevent them from entering the water drop. The sundries around the surface of the grille need to be removed.
