Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electrical pre-embedded technology, in particular to a pipeline pre-embedded part in a beam with earrings. Background Art
[0002] Electrical pre-embedding is a crucial step in electrical engineering. Traditionally, pre-embedding PVC pipes in beams and slabs requires holes in the beam bottom formwork for the pipes to pass through. This results in low beam bottom formwork utilization and severe damage. Furthermore, the holes can cause grout leakage during concrete pouring, reducing the quality and appearance of the concrete, particularly the concrete surface at the beam bottom. Therefore, a beam-mounted pipe pre-embedding component with earrings is needed to address the existing issues with pre-embedding electrical pipes in beams, which result in low beam bottom formwork utilization and poor concrete quality after the holes are opened. Summary of the Invention
[0003] The purpose of the utility model is to provide a pipeline embedded part in a beam with an earring, which can solve the problem of low utilization rate of beam bottom template after opening and poor concrete molding quality caused by embedded electrical pipelines in beams in the prior art.
[0004] The utility model is achieved in this way:
[0005] A pre-embedded pipe part in a beam with earrings comprises a fixed ear plate, a fixed earring and a PVC rigid flame-retardant tube; the fixed ear plate is in a circular ring structure and is connected to the edge of one end of the PVC rigid flame-retardant tube, so that when the PVC rigid flame-retardant tube is pre-embedded in the beam, the fixed ear plate can fit on the inner wall of the beam bottom template; a plurality of fixed earrings are respectively arranged at intervals on the outer edge of the fixed ear plate, and each fixed earring is formed with a mounting hole, so that the fixed earring is fixed to the beam bottom template through the mounting hole by a mounting piece; the other end of the PVC rigid flame-retardant tube extends to the top of the beam.
[0006] The fixed ear plate and the plurality of fixed earrings are located in the same plane, and the plane is in contact with the inner wall of the beam bottom template.
[0007] The fixed ear plate and the plurality of fixed earrings are an integrated structure.
[0008] An extension pipe is inserted into the PVC rigid flame-retardant pipe, and the extension pipe extends to the outside of the beam body.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. The utility model is provided with a fixed ear plate, a fixed earring and a PVC rigid flame retardant tube. The fixed ear plate and the fixed earring can increase the contact area between the lower end of the PVC rigid flame retardant tube and the beam bottom template. At the same time, the fixed earring is fixed to the beam bottom template by the mounting piece, thereby ensuring the pre-buried verticality and stability of the PVC rigid flame retardant tube. There is no need to drill holes in the beam bottom template, thereby avoiding the leakage of concrete pouring at the drilling position of the beam bottom template. The lower ends of the fixed ear plate, the fixed earring and the PVC rigid flame retardant tube are flush with the concrete surface of the beam bottom, which can ensure the molding quality of the concrete.
[0011] 2. Since the utility model is provided with a fixed earring, the fixed earring can be fixed to the beam bottom template by self-tapping without drilling, thereby avoiding damage to the beam bottom template to the greatest extent and improving the turnover rate of the beam bottom template.
[0012] 3. The utility model adopts PVC rigid flame retardant material to integrally form the fixed ear plate, fixed earring and PVC rigid flame retardant tube, which has low cost, simple structure and easy construction, and is conducive to reducing the impact of the cross-operation of electrical engineering and civil construction on the main structure construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 2 It is a structural schematic diagram of a pipeline embedded part in a beam with earrings (connecting extension pipes) according to the utility model.
[0015] In the figure, 1 is a fixed ear plate, 2 is a fixed earring, 201 is a mounting hole, 3 is a PVC rigid flame retardant tube, and 4 is an extension tube. DETAILED DESCRIPTION
[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0017] Please see the attached Figure 1 A pre-embedded pipeline part in a beam with earrings, comprising a fixed ear plate 1, a fixed earring 2 and a PVC rigid flame-retardant tube 3; the fixed ear plate 1 is in a circular ring structure and is connected to the edge of one end of the PVC rigid flame-retardant tube 3, so that when the PVC rigid flame-retardant tube 3 is pre-embedded in the beam, the fixed ear plate 1 can fit on the inner wall of the beam bottom template (not shown in the figure); a plurality of fixed earrings 2 are respectively arranged at intervals on the outer edge of the fixed ear plate 1, and each fixed earring 2 is formed with a mounting hole 201, so that the fixed earring 2 is fixed to the beam bottom template through the mounting piece through the mounting hole 201; the other end of the PVC rigid flame-retardant tube 3 extends to the top of the beam.
[0018] The use of PVC rigid flame-retardant tubes 3 with high rigidity and flame-retardant properties as pre-buried tubes is beneficial to reducing the impact of the cross-operation of electrical engineering and civil construction on the construction of the main structure. By fitting the fixed ear plate 1 and the fixed earring 2 with the inner wall of the beam bottom template, the contact area between the lower end of the PVC rigid flame-retardant tube 3 and the beam bottom template can be increased, thereby improving the vertical pre-buried stability of the PVC rigid flame-retardant tube 3. At the same time, by fixing the earring 2 and the beam bottom template, it is possible to ensure the pre-buried stability of the PVC rigid flame-retardant tube 3 while avoiding drilling holes in the beam bottom template, thereby avoiding the problem of concrete leakage at the drilling position of the beam bottom template and the problem of easy damage and low turnover rate of the beam bottom template. It is also beneficial to ensure the quality of concrete molding, especially the quality of the concrete surface molding of the beam bottom.
[0019] Please see the attached Figure 1 The fixed ear plate 1 and the plurality of fixed earrings 2 are located in the same plane, and the plane is in contact with the inner wall of the beam bottom template.
[0020] Preferably, two fixing earrings 2 are provided and symmetrically arranged at the two side edges of the fixing ear plate 1 , and the number of the fixing earrings 2 can also be adaptively adjusted according to actual connection requirements.
[0021] The two fixing earrings 2 and the fixing ear plate 1 are located in the same plane and can completely fit with the inner wall of the beam bottom template, ensuring the verticality and stability of the pre-buried PVC rigid flame retardant tube 3.
[0022] Please see the attached Figure 1 The fixed ear plate 1 and the plurality of fixed earrings 2 are an integrated structure.
[0023] The fixed ear plate 1 and the plurality of fixed earrings 2 are an integrated structure. The fixed ear plate 1 and the fixed earrings 2 can also be integrally formed with the PVC rigid flame retardant tube 3, thereby improving the integrity and structural strength of the embedded pipeline parts in the beam.
[0024] Please see the attached Figure 2 The PVC rigid flame-retardant tube 3 is inserted with an extension tube 4, and the extension tube 4 extends to the outside of the beam body.
[0025] The extension tube 4 can be used to lay electrical lines. The outer diameter of the extension tube 4 is slightly smaller than the inner diameter of the PVC rigid flame retardant tube 3. The size of the PVC rigid flame retardant tube 3 can be adaptively selected according to the laying amount of electrical lines, and the height of the PVC rigid flame retardant tube 3 can be determined according to the beam height.
[0026] Preferably, the extension tube 4 can be made of PVC tube or PVC rigid flame retardant tube. The shape and length of the extension tube 4 can be adaptively manufactured according to the layout design of the electrical circuit to ensure that the electrical circuit can be laid out according to the design requirements and the electrical circuit is protected by the extension tube 4.
[0027] Please see the attached Figure 1 and attached Figure 2 , the construction method of the utility model is:
[0028] The PVC rigid flame-retardant tube 3 and the extension tube 4 are manufactured according to the layout design requirements of the electrical circuit.
[0029] After the beam bottom formwork is laid, the position of the embedded pipeline parts in the beam is marked on the beam bottom formwork, and the PVC rigid flame retardant tube 3 is vertically fixed to the beam bottom formwork so that the fixed ear plate 1 and the fixed earring 2 fit on the beam bottom formwork. The fixed earring 2 is fixedly connected to the beam bottom formwork through the mounting hole 201 by self-tapping screws. There is no need to drill holes on the beam bottom formwork for vertically passing the embedded pipe, which can avoid damage to the beam bottom formwork and increase the turnover rate of the beam bottom formwork.
[0030] The steel structure of the beam body is tied, and other electrical wire pipes on the plate surface are connected with the PVC rigid flame retardant pipe 3 fixed on the beam bottom formwork in coordination with the civil construction. After inspection, the concrete of the beam body is poured. Due to the effective fit between the fixed ear plate 1 and the beam bottom formwork, there is no hole in the beam bottom formwork, which can avoid leakage during concrete pouring and ensure the appearance construction quality of the beam bottom concrete.
[0031] After the concrete pouring of the beam body is completed and the conditions for demolding are met, the bottom formwork of the beam is removed. After demolding, the self-tapping screws are removed from the fixed position of the bottom formwork of the beam to ensure the quality of concrete molding. The fixed ear plate 1 and the fixed earring 2 at the bottom of the PVC rigid flame-retardant tube 3 are flush with the concrete surface of the bottom of the beam. The PVC rigid flame-retardant tube 3 has high strength and good flame retardant effect. Later masonry construction and other operations are not likely to cause damage to the pre-buried electrical pipe. When arranging the electrical lines, one end of the extension tube 4 can be inserted into the PVC rigid flame-retardant tube 3, and the other end of the extension tube 4 can be extended to the outside of the beam body according to the arrangement of the electrical lines.
[0032] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
