Depth control device and depth control method of pipeline pressure groove on structural plate

Abstract

The invention discloses a depth control device and a depth control method for pipeline pressure grooves on a structural plate, belonging to the technical field of pipeline laying in hydropower installation and construction. The present invention includes a control body, a bearing body and a pressure groove body, the control body can be adjusted and installed on the structural plate, the bearing body includes a bearing main body and a bearing auxiliary body, the bearing main body is installed on the control body through threads and is located on the Above the structural plate, the side of the bearing body facing away from the control body is provided with an installation groove, and an elastic waterproof member is installed at the notch of the installation groove, and the bearing auxiliary body is installed inside the installation groove, and the bearing auxiliary body The pressure groove body is detachably connected with the pressure groove body, and after the connection, the pressure groove body is bonded to the surface of the elastic waterproof part. Accurately control the depth of the pressure groove, and at the same time ensure the thickness of the steel protection layer more efficiently, and the formed concrete surface layer is not easy to be 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.
