Abstract
Description
Technical Field
[0001] The invention relates to the technical field of construction engineering, and in particular to a prefabricated product with reserved wall-penetrating sleeve device. Background Art
[0002] During the reserved and embedded construction stage, waterproof casings need to be reserved in advance at the locations where the pipes pass through the wall. When the pipes are installed, there will be a gap between the pipes and the waterproof casings, which needs to be sealed with fireproof materials. The existing practice is to first use hemp to fill the gap between the pipes and the casing after the pipes are installed, and then use fireproof mud to fill the gap between the hemp to achieve the purpose of sealing the gap between the pipes and the casing. The existing fireproof sealing construction process is time-consuming, and the sealing effect is greatly affected by the workers' construction process level, which is prone to secondary repairs. Utility Model Content
[0003] The invention discloses a prefabricated reserved wall-penetrating sleeve device, the purpose of which is: 1. to solve the problem that the process flow of fireproof plugging between pipeline and sleeve is complicated and time-consuming; 2. to solve the problem that the fireproof plugging effect between pipeline and sleeve is not good and needs to be repaired.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A prefabricated reserved wall sleeve device comprises a reserved sleeve, an internal pipe, an end cap and a sealing material layer. The two ends of the reserved sleeve are connected with the end caps, the internal pipe is arranged in the reserved sleeve, a sealing material layer is arranged between the internal pipe and the reserved sleeve, and the two ends of the internal pipe are located in the end caps.
[0006] Preferably, the reserved sleeve comprises a sleeve body, a plurality of annular anti-pull-out plates are integrally formed on the outer wall of the sleeve body, and the annular anti-pull-out plates are pre-buried in the concrete of the wall.
[0007] Preferably, both ends of the sleeve body protrude from the wall with the same protruding length, and the end of the sleeve body is connected to the end of the end cap by threaded connection or fastened by a clamp assembly.
[0008] Preferably, both ends of the built-in pipe protrude from the sleeve body with the same protruding length, and a rubber pad is provided on the bottom inner surface of the end cap, and both ends of the built-in pipe are pressed and sealed with the rubber pad.
[0009] Preferably, the blocking material layer is made of fireproof material.
[0010] Preferably, a limiting ring is further provided on the outer wall of the built-in pipe at the positions of the two ends of the reserved sleeve, and the limiting ring closes the outer port of the sealing material layer.
[0011] Preferably, the limiting ring is screwed to the outer wall of the built-in pipe or bonded with glue.
[0012] The beneficial effects of the novel prefabricated wall-penetrating sleeve device are as follows:
[0013] 1. By advancing the fireproof sealing process, there is no need to worry about leakage of the reserved casing during the period from the completion of casing reservation to the completion of pipeline installation.
[0014] 2. During the pipeline installation and construction phase, it is only necessary to connect the pipeline to the built-in pipeline in the device, without the need for fireproof sealing, which greatly reduces the time required for the pipeline installation and construction phase.
[0015] 3. Through mass production in the factory, the quality of fireproof sealing can be more stable and will not be affected by the workers' construction technology level.
[0016] 4. The clamp assembly and end cap removed during pipeline installation can be reused, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] In order to more clearly illustrate the technical solution of the present invention, the following briefly introduces the drawings required for use in the embodiments, which constitute a part of the specification and are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation to the present invention.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] A prefabricated wall bushing device, such as Figure 1 As shown, it includes a reserved sleeve 3, a built-in pipeline 2, an end cap 5, and a sealing material layer 8. The two ends of the reserved sleeve 3 are connected with the end caps 5, the built-in pipeline 2 is arranged in the reserved sleeve 3, a sealing material layer 8 is provided between the built-in pipeline 2 and the reserved sleeve 3, and the two ends of the built-in pipeline 2 are located in the end caps 5.
[0022] like Figure 1 As shown, the reserved sleeve 3 includes a sleeve body, and a plurality of annular anti-pullout plates 4 are integrally formed on the outer wall of the sleeve body. The annular anti-pullout plates 4 are pre-buried in the concrete of the wall 1 .
[0023] like Figure 1 As shown, both ends of the sleeve body protrude from the wall 1 and the protruding lengths are consistent, and the end of the sleeve body is connected to the end of the end cap 5 by threaded connection or fastened by a clamp assembly.
[0024] like Figure 1 As shown, both ends of the built-in pipe 2 protrude from the sleeve body and the protruding lengths are consistent, and a rubber pad 6 is provided on the bottom inner surface of the end cap 5, and both ends of the built-in pipe 2 are pressed and sealed with the rubber pad 6.
[0025] like Figure 1 As shown, the blocking material layer 8 is made of fireproof material.
[0026] like Figure 1 As shown, a limiting ring 9 is further provided on the outer wall of the built-in pipe 2 at the positions of the two ends of the reserved sleeve 3 , and the limiting ring 9 closes the outer port of the blocking material layer 8 .
[0027] like Figure 1 As shown, the limiting ring 9 is screwed to the outer wall of the built-in pipe 2 or bonded with glue.
[0028] The new type can be prefabricated in the factory and installed between the relative templates during the process of pouring the wall. After forming, the complicated installation process of the built-in pipeline can be avoided, especially the blocking process between the built-in pipeline and the reserved casing can be avoided. The large-scale production of the factory can reduce the cost of the prefabricated parts, while ensuring the sealing degree of the blocking layer, saving a lot of processes and improving production efficiency. When installing the pipeline later, it is only necessary to remove the end cap to connect the built-in pipeline with the subsequent pipeline. Before installing the subsequent pipeline, the risk of leakage can be avoided by the new type.
