Description

Technical Field

[0001] The present invention relates to a method for setting a concealed pipeline structure, and also relates to a method for setting a concealed pipeline comprising the concealed pipeline structure. Background Art

[0002] The main construction phase of a building typically involves only completing the foundation work for walls and floors without any surface treatment. This type of building is called a rough-hewn house. The work performed within a specific area to transform a house into a habitable space is often referred to as decoration or renovation. Plumbing and electrical installation are essential components of a renovation project, requiring the installation of pipes in both exposed and concealed configurations. Exposed pipes, however, take up space and compromise the aesthetics, making concealed pipe installation the mainstream method.

[0003] In the prior art, the mainstream method for burying concealed pipes is on-site grooving. When pipes cross a room, grooves are usually made on the ground, ceiling, or wall, and the pipes are buried and then sealed with cement mortar. The disadvantages of on-site grooving are noise, dust pollution, health hazards, etc. Another way to bury concealed pipes is to reserve burial space when pouring the floor slab. The advantage of this method is that the burial space is reserved in advance, and there is no need to grooving during the later decoration. The disadvantage is that the process is cumbersome. For example, when pre-burying the pipes, it is necessary to drill holes on the template on-site so that the pipe interface passes through the template. When only the burial space is reserved, the template supported in the burial space cannot be removed. For example, a template device for reserving pipe openings in floor slabs with publication number CN105952152B is provided. An alternative solution is to fill the burial space with materials such as foam, and then remove the filling material when the pipes are buried. It is also difficult to fix the filling material and prevent deformation. Summary of the Invention

[0004] In view of the above shortcomings, the object of the present invention is to provide a method for concealed burying of pipelines, which is convenient for burying pipelines during the decoration process.

[0005] To this end, the present invention provides a method for setting up a concealed pipe structure, in which a concealed pipe structure is preset in a floor slab, and the surface of the concealed pipe structure does not exceed the surface of the floor slab, and the concealed pipe structure is cast in situ using a formwork system; the formwork system includes a formwork and a supporting formwork device for forming a rectangular concealed pipe structure, the supporting formwork device is supported on the surface of the formwork, and the formwork of the formwork system is fixed to the floor slab casting formwork; the length of the support rod of the supporting formwork device is adjustable, and the formwork in the horizontal direction or the vertical-horizontal direction is fixed to the support rod.

The concealed pipe structure 2 is cast in situ using a formwork system; the formwork system includes a formwork 204 for forming a rectangular concealed pipe structure and a formwork device 3, the formwork device 3 is supported on the surface of the concealed pipe structure formwork 204, and the concealed pipe structure formwork 204 is fixed to the floor slab formwork 101; the length of the support rod of the formwork device 3 is adjustable, and the concealed pipe structure formwork 204 in the horizontal direction or the vertical direction is fixed to the support rod. When the floor slab 1 is cast, the formwork connected to the support rod is driven away from the concrete surface by shortening the length of the support rod to realize the removal of the formwork. In Example 1 of the present invention, with reference to Figure 1 As shown, the pipeline buried structure 2 is a buried hole set inside the floor 1. The buried hole and the floor 1 are cast in one piece. First, the floor template 101 is spliced, and a scaffold is set for support. Then, the pipeline buried structure template 204 is assembled. Figure 3As shown in the structure, the bottom template 201 and the side template 202 of the pipeline buried structure 2 are fixed to the side plate of the floor template 101 with bolts 5, and a supporting formwork device 3 is set inside the pipeline buried structure 2.
