Description

Technical Field

[0001] The invention belongs to the technical field of house construction and installation engineering, and specifically relates to an integrated steel structure embedded part with a drainage pipe. Background Art

[0002] Generally, in large-space structural projects such as large exhibition halls, because a certain aesthetic effect needs to be achieved, drainage pipes are generally designed to be hidden, and are pre-buried with the help of structural columns or shaped steel structures. The pre-buried drainage pipes and steel structures may cause collision and positioning problems, and the construction process is relatively complicated.

[0003] For example, the Chinese patent number CN202020123456.7, entitled A rainwater pipe embedded plate for buildings and its installation method, discloses a method of drilling a hole in the center of a single-layer embedded plate for the passage of rainwater pipes. However, it does not design any flanges or limiting structures, and relies solely on concrete filling to stabilize the position of the pipe. Therefore, it lacks a pipe limiting structure, which makes it easy for the rainwater pipe to deviate during the pouring and vibration process, and it is difficult for the concrete filling to maintain a vertical positioning for a long time, and there is a risk of leakage and pipe deformation in the later stage. Moreover, it is impossible to integrate the rainwater inlet with the embedded parts, and it is necessary to install a rainwater inlet or rainwater bucket on site. There are many construction interfaces and it is easy to leak, and the entire pre-embedding cannot be completed at one time.

[0004] Another example is the Chinese patent number CN201710876543.1, entitled A Steel Structure Curtain Wall Supporting Embedded Parts for Water Supply and Drainage, which discloses a circular hole reserved on the node plate of the steel structure for pipe threading, and a temporary support for the position of the pipe by an external bracket. The bracket is separated from the embedded plate and connected by bolts. However, it has the same technical features as the comparative document CN202020123456.7, with a low degree of integration of embedded parts, and external brackets need to be assembled on-site for pipe support. The node plate is separated from the bracket, and the construction is cumbersome and the degree of streamlining is low. Positioning depends on bolt tightening, the on-site tightening error is large, and the pipe is easy to sink after the bolts are loosened, and reliable limiting fixation of the "flange limit" type cannot be achieved.

[0005] Another example is the Chinese patent number CN201620345678.9, entitled A Multifunctional Steel Mesh Embedded Part, which discloses a method of welding water supply and drainage pipes to steel mesh to form an integrated "mesh and pipe" embedded part, which can simultaneously lay steel bars and pipes in concrete. The pipes and steel mesh are connected by spot welding without additional limiting structures. However, this technology does not use special limiting flanges, and the spot welding connection can only preliminarily fix the pipes, which is relatively fragile. Concrete vibration and steel bar binding operations can easily cause pipe dislocation. At the same time, this comparative document involves the installation of rainwater outlets, but focuses on the integration of steel bars and pipes. It does not provide a direct docking device with commercially available rainwater gutters and rainwater outlets, and still requires on-site assembly.

[0006] Another example is the Chinese patent number CN201510998765.3, and the invention name is a pre-buried device for a curtain wall drainage system. It discloses a reserved trough plate at the bottom edge of the curtain wall, and the pipe is inserted from the bottom to the top, relying on the folded edge of the trough plate for lateral support. However, this device is limited to horizontal support, and the lateral support can only limit the horizontal displacement, and does not have axial positioning or height limiting functions. The folded edge support has no limit effect on the up and down directions of the pipe, and cannot maintain vertical height positioning. At the same time, the construction interface of the device is complex, and it is necessary to equip a rain gutter with the folded edge trough plate for splicing, and multiple sealing points at the interface increase the risk of leakage.

[0007] Therefore, the known method for processing embedded parts of drainage pipes has the above-mentioned inconveniences and problems. Summary of the Invention
