Description

Technical Field

[0001] The utility model relates to the technical field of fixing casing pipes passing through floor slabs of industrial and civil buildings, in particular to a simple device for fixing the center of the casing pipe. Background Art

[0002] Floor pipe hanging holes refer to holes opened in the floor of a building for installing pipes. During the construction of a building, in order to facilitate the installation and maintenance of the pipeline system, hanging holes are usually left in the floor in advance. These hanging holes are usually planned and designed by engineers and designers according to project requirements and pipeline layout to ensure the stability and safety of the pipeline. Hanging holes can be used to install various pipes, such as water supply pipes, drainage pipes, wires and cables, etc., so that the pipes can pass through the floor and connect with the pipes of the upper and lower buildings.

[0003] The existing device is usually installed by two or more people in the pipe hanging hole through the floor slab. The vibration of the pipe during installation can easily cause the pipe to have a large deviation at the center of the casing, which can easily cause the chimney effect caused by the fireproof mud not being sealed tightly in the later stage. This is a common quality problem of most projects. With the rapid development of society, quality requirements are getting higher and higher, the labor force is getting less and less, and the labor cost is getting higher and higher.

[0006] (II) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0014] Wherein, the baffle is located below the floor slab.

[0015] Preferably: the sleeve limiting ring is fixedly installed with the baffle;

[0016] Wherein, the sleeve limiting ring above the baffle is in contact with the sleeve body.

[0017] Preferably: each group of the pipe clamps is located on the circumferential surface of the casing limiting ring below the baffle;

[0018] Wherein, each group of the pipe clamps is fixedly installed with the casing limiting ring.

[0019] Preferably: the two bolts are located between the pipe clamps;

[0020] Wherein, each group of pipe clamps is slidably mounted with bolts.

[0021] (III) Beneficial effects

By placing the casing limit ring inside the casing body, and only needing to rotate the nut on the bolt to make each group of pipe clamps move away from each other, and drive the casing limit rings on the baffle to fit together, the casing body can be fixed. The operation is convenient, and one person can complete the fixation of the casing body, reducing the input of construction labor, and there is no need to support the casing body above the floor slab.
