Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a heat preservation structure of a pipeline wall-penetrating hole. Background Art

[0002] Pipe penetration construction is a common construction on building wall panels. It is mainly used to lay common pipes such as air-conditioning pipes and heating pipes. Especially in air-conditioning pipes, the space inside and outside the building is directly opened up. Generally, it is necessary to drill holes in the wall and then directly pass the pipes through the holes to connect the air-conditioning outdoor unit. The wall holes in this position involve related construction of sealing and insulation to ensure the insulation effect of the building at the drilling site.

[0003] At present, the insulation method for such boreholes is to directly inject foam glue or inject building sealant between the inner wall of the borehole and the pipe. However, the above methods are not strong enough to support the pipe in actual construction, that is, the foam glue is easy to deform, the adhesion between the building sealant and the inner wall of the borehole is not enough, or there is a cavity in the injection of glue, etc. Under the pressure of the pipe, the sealing position in the borehole is also easy to loosen, which will cause air leakage at the borehole after a period of time and lose the insulation effect. In order to solve this problem, it is necessary to design an insulation structure for the pipe through-the-wall hole. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] See also Figure 1-2 The heat preservation structure of the pipe through-wall hole comprises a wall 1, a prefabricated hole 2 is provided on the wall 1, a pipe arrangement cavity 3 is provided in the prefabricated hole 2, and the pipe arrangement cavity 3 is arranged through the prefabricated hole 2. The prefabricated hole 2 and the pipe arrangement cavity 3 can also be prefabricated when the floor is constructed to improve the relevant construction efficiency;

[0024] A slurry injection cavity structure is provided on one side of the pipeline arrangement cavity 3 to inject sealing slurry into the inner side of the pipeline arrangement cavity 3, wherein the slurry injection cavity structure is arranged away from the pipeline arranged in the pipeline arrangement cavity 3, so that the injection of slurry or building sealant is not hindered, and the sealant does not contact the wall during the injection process, so as to avoid the loosening of building particles affecting the adhesive fixing effect;

[0025] And a suspended support structure, which is arranged on the inner side of the pipeline arrangement cavity 3 to suspend the pipeline on the inner side of the pipeline arrangement cavity 3 so that the sealing slurry injected from the slurry injection cavity structure can enter the gap between the inner side of the pipeline arrangement cavity 3 and the pipeline for sealing and heat preservation. This structure allows the inner side of the pipeline arrangement cavity 3 and the pipeline to be fully injected with building sealant for sealing, and the smooth spatial structure allows the sealant to be smoothly injected, thereby ensuring the use effect of the building sealant, thereby improving the sealing and heat preservation effect of the pipeline wall hole.

[0026] Furthermore, both ends of the pipe arrangement cavity 3 extending out of the wall 1 are provided with outer edge sealing plates 4 which are fitted on the wall surface of the wall 1. The outer edge sealing plates 4 at both ends of the pipe arrangement cavity 3 can be installed at both ends of the pipe arrangement cavity 3 by threaded connection or bolt connection, so that the outer edge sealing plates 4 at both ends of the pipe arrangement cavity 3 are tightly fitted on the wall surface. This structure can ensure the stability between the pipe arrangement cavity 3 and the wall, and can also be further fixed by gluing to ensure the stability between the pipe arrangement cavity 3 structure and the wall, so as to ensure the support stability of the pipe after the pipe is arranged.

[0027] Furthermore, the slurry perfusion cavity structure includes an injection cavity 5 , which is arranged on the outer surface of the pipeline arrangement cavity 3 along the axial direction of the pipeline arrangement cavity 3 , and an injection hole 6 is opened at one end of the injection cavity 5 .

[0030] Furthermore, a plurality of annular support bodies 8 are evenly distributed in the axial direction in the pipeline arrangement cavity 3, so as to evenly support the pipeline in the pipeline arrangement cavity 3 and stably support the pipeline.

[0031] During the process of installing the pipeline, the device allows the pipeline to pass through the pipeline arrangement cavity 3, and then pressurizes the building sealant into the injection cavity 5 through the injection hole 6. After the injection cavity 5 is filled with the sealant, the sealant enters the pipeline arrangement cavity 3 through the multiple liquid inlet holes 7, and further flows through the multiple notches 9 between the circular ring support body 8 and the pipeline, so that the sealant quickly fills the pipeline arrangement cavity 3 to achieve a good sealing effect. The circular ring support body 8 on the pipeline arrangement cavity 3 can rigidly support the pipeline. On the premise of ensuring stable support for the pipeline, it can also ensure a good sealing and heat-insulating effect, so that the pipeline wall hole has a good heat-insulating structure for heat preservation.
