Description

Novel overflow pipe assembly applied to metal gutter

Technical Field

The utility model relates to a novel overflow pipe assembly, which is mainly applied to a metal gutter and belongs to the technical field of overflow facilities.

Background

Currently, metal roofing materials have been widely used in industrial and civil construction, which have better appearance and economy, but the demand for water resistance has increased accordingly. The roof gutter and the downpipe are one of the components of a drainage system positioned on the side surface of a roof of a building, and the main functions of the roof gutter and the downpipe are to drain rainwater to the outdoor or the ground rapidly and timely, and the capacity is related to the intensity of the design storm. When an extreme rainfall environment or a drainage system is blocked, the water storage in the gutter cannot be timely discharged through the downpipe, so that a backflow phenomenon is easy to occur, and property loss is caused.

In the prior art, a wall overflow port is usually arranged to realize gutter drainage in an emergency state. However, in recent years, as the requirements of industry owners on the beauty of the facade of a building are higher and higher, the way of arranging overflow ports on the wall and holes on the wall is gradually not accepted by the owners because the overflow ports and the holes on the wall can influence the modeling of the facade to a certain extent.

Accordingly, the present utility model has been made.

Disclosure of utility model

Aiming at the technical problems in the prior art, the utility model aims to provide a novel overflow pipe assembly applied to a metal gutter, which does not need to open holes in a wall surface, ensures the integrity of a facade effect, and realizes timely drainage of gutter water storage under the condition of extreme rainfall environment or blockage of a drainage system.

In order to achieve the above purpose, the utility model is realized by the following technical scheme:

The utility model provides a be applied to novel overflow pipe subassembly of metal gutter, includes the gutter, install the elbow on the gutter, the below of elbow is connected with the overflow pipe, and elbow and overflow pipe intercommunication.

And a grate is arranged at the inlet of the elbow.

The gutter is connected with a downpipe, the downpipe is arranged on one side of the overflow pipe, and a rainwater hopper is arranged on the downpipe.

The beneficial effects of the utility model are as follows:

The elevation of the top end of the water inlet of the elbow is not higher than the maximum water depth of the gutter, the elevation of the bottom end of the water inlet is preferably arranged at the position of the designed maximum water depth, and when the water storage amount in the gutter reaches the height of the water inlet of the overflow pipe, the overflow pipe still has an increasing trend, and the overflow pipe is started to discharge the surplus water. The water inlet end of the elbow is provided with a grate for blocking solid foreign matters from entering the overflow device, the elbow is sleeved on the overflow pipe and fixed by a pulling rivet. According to the utility model, holes are not required to be formed in the wall surface, so that the integrity of the effect of the vertical surface is ensured; and the rainwater is not required to drain from the wall surface, and the rainwater is converged and can not directly impact the road and the pedestrians due to gravitational potential energy, so that the road surface integrity and the pedestrian safety are ensured.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

FIG. 2 is a schematic elevational cross-sectional view of the present utility model;

Wherein, 1 is a gutter, 2 is an overflow pipe, 3 is an elbow, 4 is a grate, 5 is a rain bucket, and 6 is a downpipe.

Detailed Description

The present utility model will be further described with reference to specific examples, but the scope of the present utility model is not limited thereto.

As shown in fig. 1 and 2, the novel overflow pipe assembly is applied to a metal gutter, an elbow 3 is arranged on the gutter 1, an overflow pipe 2 is connected below the elbow 3, and the elbow 3 is communicated with the overflow pipe 2. The overflow pipe 2 passes through the gutter 1 to be led to the rainwater well, the elbow 3 is sleeved on the overflow pipe 2, the direction is consistent with the direction of the gutter 1, and the elbow 3 is provided with the grate 4 for preventing solid foreign matters from entering the overflow device. The skirt edge of the overflow device should be welded on the gutter 1 on site, and the welding seam should be ensured to be continuous, sealed and waterproof during welding. The gutter is connected with a downpipe 6, the downpipe 6 is arranged on one side of the overflow pipe 2, and the downpipe 6 is provided with a rain bucket 5.

The installation mode of the overflow pipe assembly in the gutter 1 is as follows: firstly, the installation position of the overflow pipe assembly is determined in the gutter 1, and a notch is formed on the gutter 1 on site according to the size of the overflow pipe assembly. The overflow pipe assembly is then inserted into the notch of the gutter 1, and then welded to the gutter 1 in situ along the skirt of the overflow pipe assembly, wherein the welding is ensured to be continuous and sealed and waterproof.

When the rain weather is extreme, the water storage in the gutter 1 can not be timely discharged by the downpipe 6, an overflow pipe assembly is started, and rainwater can enter the overflow pipe 2 through the elbow 3; when the drainage system is blocked by solid foreign matters, rainwater cannot normally enter the drainage system to be discharged through the rainwater hopper 5, the water stored in the gutter 1 reaches a design value, the overflow pipe assembly is started, the rainwater can enter the overflow pipe 2 through the elbow 3, meanwhile, the grate 3 can block the floatable solid foreign matters from entering the overflow pipe assembly, after the water level is lowered, the solid foreign matters can fall into the gutter 1 again, and the subsequent cleaning is waited.

The above embodiments are only for illustrating the inventive concept of the present utility model and not for limiting the protection of the claims of the present utility model, and all the insubstantial modifications of the present utility model using the concept shall fall within the protection scope of the present utility model.
