Description

Technical Field

[0001] The utility model specifically relates to a multi-fin built-in water drop structure, belonging to the technical field of building water supply and drainage. Background Art

[0002] According to the requirements of relevant drainage specifications, scattered drainage of buildings in northern regions is not allowed, and organized drainage must be carried out. At present, there are generally two types of drainage arrangements, one is the drainage pipe arrangement, and the other is the gutter arrangement. Both are external drainage arrangements for walls. When used in winter, the drainage holes of the gutter will be blocked due to the low external temperature, forming a closed trough structure. The continuous accumulation of water will form an ice layer, causing its own excessive load and falling. The drainage pipe will also be easily frozen and blocked in winter due to its circumferential seal, causing it to load a longer ice mass inside and increase its own weight, posing a risk of falling. In addition, most of the current drainage pipes are made of PVC plastic, which is easy to break after freezing and swelling at low temperatures, especially in residential areas and drainage systems equipped on bridges. Damage problems are frequent.

[0003] During the building renovation and reinforcement process, the built-in drainage pipes are highly concealed and difficult to inspect. Currently, it is usually chosen to install external drainage pipes after laying the insulation layer. However, the frost heave problem of the drainage pipes caused by the external structure still exists and has not been solved. The main reason for the frost heave of the drainage pipes is the external installation method itself. The surrounding outer walls are exposed, so the freezing situation cannot be improved, and additional insulation measures are required, which increases the complexity of the process and subsequent maintenance. In addition, the structural form of the drainage pipes hanging on the wall will also destroy the flatness of the building's exterior wall, and its external layout also limits the drainage layout position and number. Utility Model Content

[0004] In order to overcome the defects of the prior art, a multi-fin built-in water drop structure is now provided to solve the above problems.

[0005] A multi-fin built-in water drop structure, comprising a back plate, side plug strips, a front baffle plate and two side plates, the front baffle plate and the back plate are arranged vertically in parallel, the back plate is arranged close to the building outer wall, the front baffle plate is arranged away from the building outer wall, the side of the back plate facing the building outer wall is connected to the building outer wall, two side plates are arranged vertically in parallel between the front baffle plate and the back plate, one side of each side plate is fixedly connected to the back plate, and the other side of each side plate is fixedly connected to the front baffle plate, a water drop cavity is enclosed between the back plate, the front baffle plate and the inner walls of the two side plates, a strip-shaped notch is processed along the length direction of the front baffle plate, and the side plug strip is detachably connected to the strip-shaped notch;

[0006] Each side of the back plate is integrally connected with a first fin, each side of the front baffle is integrally connected with a second fin, and a clamping portion is formed between the outer wall of each side plate and the first and second fins adjacent thereto.

[0007] The beneficial effects of the utility model are:

[0008] 1. The utility model is a built-in drainage structure of flat tubes and multiple fins. Its detachable structure makes it convenient for regular maintenance even when it is in a built-in state, and the built-in form directly improves its thermal insulation performance. Through the cooperation between the back plate, the side plugs, the front baffle and the two side plates, a drainage structure built into the thermal insulation layer or the decorative layer on the exterior wall of the building can be realized. While providing double-sided thermal insulation performance with the help of the thermal insulation layer or the decorative layer, it can also achieve double-sided shielding of its own structure with the help of the clamping cooperation of the thermal insulation layer or the decorative layer, reduce the exposed area of ​​the structure, help improve the thermal insulation performance, and reduce the probability of low-temperature frost heave.

[0009] 2. The matching relationship between the side plug strips and the strip-shaped notches on the front baffle of the utility model can not only provide a position for the exposed inspection of the drain cavity, but also facilitate the timely positioning and directional cleaning of blockages in the drain cavity. The concealed setting of the side plug strips is not only conducive to improving the flatness of the appearance of the utility model after installation, but also can cooperate with the overall structure of the utility model to improve the flatness of the building facade.

[0010] 3. The utility model is particularly suitable for the secondary insulation reinforcement operation in old residential buildings, avoiding the damage of existing plastic external downpipes due to frost heave. The utility model can reduce the relevant requirements on the low temperature resistance of downpipe manufacturing materials. The built-in arrangement is more conducive to its durable use and is suitable for popularization. BRIEF DESCRIPTION OF THE DRAWINGS
