Depth control device and method for pipeline pressing groove in structural plate

Abstract

The invention discloses a depth control device and method for a pipeline pressing groove in a structural plate, and belongs to the technical field of pipeline laying in water and electricity installation construction. The depth control device comprises a control body, a bearing body and a pressing groove body, wherein the control body is adjustably installed on the structural plate; the bearing body comprises a bearing main body and a bearing auxiliary body; the bearing main body is installed on the control body through threads and is located above the structural plate; an installation grooveis formed in one side, back to the control body, of the bearing main body; an elastic waterproof part is installed at the groove opening of the installation groove; the bearing auxiliary body is installed inside the installation groove; the bearing auxiliary body is detachably connected with the pressing groove body; and the pressing groove body is attached to the surface of the elastic waterproofpart after the bearing auxiliary body is connected with the pressing groove body. According to the depth control device and method, the depth of the pressing groove can be accurately controlled, meanwhile, the thickness of a steel bar protection layer can be guaranteed more efficiently, and a formed concrete surface layer is not prone to being damaged.

Description

technical field [0001] The invention relates to the technical field of pipeline laying in hydropower installation and construction, in particular to a depth control device and method for pipeline pressure grooves on a structural plate. Background technique [0002] In the construction of houses, it is often required to carry out concealed laying of pipelines in the later stage, and the process of pressing grooves needs to be added for concealed laying. When the pipeline that needs to be concealed is placed on the structural slab, the usual way to press the groove is: 1. Before the concrete is poured, use a steel pipe (or PVC pipe) with the same diameter to fix it on the slab reinforcement with an iron wire, and wait until the concrete has a certain strength. Finally, take out the steel pipe (or PVC pipe); 2. After the concrete has just been poured, manually place the steel pipe (or PVC pipe) on the predetermined position, quickly and lightly press out the groove, and then re...

AI Technical Summary

Problems solved by technology

In the former, the pipeline is not easy to fix firmly on the bound gluten, and the gluten is easy to be stepped on during the pouring of concrete, resulting in changes in the position of the pipeline; in the latter, the depth of the pressure groove is affected by human factors of the operator very big

Both of the above two methods exist: the depth of the pressed groove is not easy to be well controlled, and often the groove is too deep, which takes up too much thickness of the plate reinforcement protective layer, and even causes the plate thickness to exceed the allowable deviation range; it is easy to damage Formed concrete surface, etc.
