Description

Water and electricity pipeline pre-embedded upturned end fixing device Technical Field

[0001] This utility model relates to the field of building construction, and in particular to an upturned end fixing device for pre-embedding water and electricity pipelines. Background Technology

[0002] When pre-installing water and electricity pipes in floor slabs, the end of the pipe closest to the wall needs to be turned upwards to connect with other pipes embedded in the wall. Currently, in pipe pre-installation construction, the turned-up ends of multiple pipes are usually fixed to the reinforcing steel frame using short pipes (plastic pipes), and the pipe openings are sealed with tape or professional caps to prevent concrete from entering the pipes during pouring. This traditional method of fixing the turned-up ends of pre-installed pipes is unreliable and prone to loosening and displacement during concrete vibration, potentially causing problems such as inability to connect with the pre-installed pipes in the wall (e.g., severe pipe tilting).

[0003] Application number CN201910815547.X discloses a pre-embedded positioning and fixing device for water and electricity pipelines in floor slabs. Although this fixing device can effectively fix the pipelines, it requires the pipelines to pass through the through-holes in a square tube. After passing through the hole, it can only achieve limited positioning; if it is to be fixed, the pipelines still need to be tied and secured. In addition, this fixing device cannot flexibly move the position of the pipelines, resulting in low flexibility. Therefore, although this device has a simple structure, it suffers from problems such as high operational difficulty, the need to fix the pipelines, and the inability to flexibly adjust the pipelines.

[0004] Based on this, this application provides a water and electricity pipeline pre-embedding device with a reasonable structural design, simple fixing operation, and flexible adjustment of pipeline position. Summary of the Invention

[0005] This utility model aims to solve the technical problems existing in the prior art. To this end, this utility model provides a water and electricity pipeline pre-embedding fixing device with a reasonable structural design, simple fixing operation, and flexible adjustment of pipeline position.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A device for fixing the upturned end of a water and electricity pipeline for pre-embedding is provided, including a gantry-type fixing bracket installed on a steel reinforcement frame. The fixing bracket is provided with multiple fixing units for fixing water and electricity pipelines. Each fixing unit includes a sleeve movably installed on the fixing bracket, a hook plate provided on the side of the sleeve, a clamp fixed to the water and electricity pipeline and connected to the hook plate, and a plug plate detachably installed on the hook plate for sealing the end of the water and electricity pipeline.

[0008] In some alternative embodiments, a locking bolt is screwed to the top of the sleeve for securing the sleeve to a fixed bracket.

[0009] In some alternative embodiments, the hook plate has a hook groove on the side wall away from the sleeve, and the clamp has a hook on the side wall that is connected to the hook groove.

[0010] In some alternative embodiments, one end of the bottom of the blocking plate is provided with a plug for inserting into the water and electricity pipeline for sealing, and the other end of the blocking plate is provided with a fixing rod, the bottom stud of which passes through the hook plate and is screwed to a nut.

[0011] In some alternative embodiments, the fixing bracket includes a crossbeam, screws at both ends of the crossbeam, fixing nuts at the bottom of the crossbeam and screwed to the screws, and an inner threaded tube screwed to the bottom of the screws, wherein the inner threaded tube is welded to the reinforcing steel frame.

[0012] In some alternative embodiments, both the beam and the sleeve are made of square steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model fixes the upturned end of the pre-embedded pipeline to the fixing unit of the fixing bracket. The fixing unit can be flexibly adjusted on the fixing bracket, which is equivalent to flexibly adjusting the position of the pipeline. The designed fixing unit uses a clamp to hold the pipeline, and then hangs the clamp on the hook plate to fix the pipeline in the circumferential direction. Finally, the pipe opening is sealed with a plug plate, and the pipeline is fixed in the axial direction on the hook plate to achieve pipeline fixation. This fixing device has a simple structure, quick fixing operation, and does not require pipeline perforation. Attached Figure Description

[0028] Example 1

[0029] As shown in Figure 1, this embodiment provides an upturned end fixing device for pre-embedded water and electricity pipelines, including a gantry-type fixing bracket 1 and multiple fixing units 2 for fixing water and electricity pipelines disposed on the fixing bracket.

[0030] As shown in Figures 1 and 5, the fixed bracket 1 includes a crossbeam 1.1, threaded rods 1.2 at both ends of the crossbeam, a fixing nut 1.3 at the bottom of the crossbeam and threaded to the threaded rods 1.2, and an internal threaded tube 1.4 threaded to the bottom of the threaded rods 1.2. The internal threaded tube 1.4 is welded to the reinforcing steel frame (the reinforcing steel frame of the floor slab). During installation, the threaded rods are first welded to the reinforcing steel frame, then inserted from the top of the crossbeam, the fixing nut is screwed onto the threaded rod, the threaded rod is threaded to the internal threaded tube, and finally the crossbeam is fixed by tightening the fixing nut. Preferably, the crossbeam in this embodiment is made of square steel.

[0031] As shown in Figure 2, the fixing unit 2 includes a sleeve 2.1 movably mounted on the fixing bracket 1, a hook plate 2.2 located on the side of the sleeve, a clamp 2.3 fixed to the water and electricity pipeline 3 and connected to the hook plate 2.2, and a plug plate 2.4 detachably mounted on the hook plate 2.2 for sealing the end of the water and electricity pipeline. The sleeve 2.1 is a square tube that is fitted onto the crossbeam 1.1. To lock the position of the sleeve, a locking bolt 2.5 is screwed to the top of the sleeve 2.1 in this embodiment. After adjusting the position of the sleeve, tightening the locking bolt will fix the sleeve to the crossbeam.

[0032] The hook plate 2.2 and clamp 2.3 of this embodiment have the following connection structure: as shown in Figures 2 and 3, the hook plate 2.2 has a hook groove 2.2.1 on its side wall away from the sleeve 2.1, and the clamp 2.3 has a hook 2.3.1 on its side wall that is connected to the hook groove 2.2.1. In practice, the clamp can be fixed to the upper end of the pre-embedded pipeline first, and then the hook on the clamp can be hooked into the hook groove of the hook plate, which can limit the circumferential direction of the pipeline.

[0033] As shown in Figure 4, one end of the bottom of the blocking plate 2.4 is provided with a plug 2.4.1 for insertion into the water and electricity pipeline for sealing. The other end of the blocking plate 2.4 is provided with a fixing rod 2.4.2. The bottom stud of the fixing rod 2.4.2 passes through the hook plate 2.2 and is screwed to the nut 2.6. The blocking plate can seal the pipe opening to prevent concrete from entering the pipeline and causing blockage during pouring. On the other hand, the blocking plate can also limit the axial direction of the pipeline.

[0034] This embodiment uses a fixing unit to secure the flipped end of the pre-embedded pipeline, and also allows for flexible adjustment of the fixing unit's position to adjust the pipeline's location. After the concrete has hardened, the clamps and fixing nuts can be loosened, and the screw can be unscrewed from the internal thread to remove the fixing device for reuse.

[0035] It is worth noting that: for hanging wires of different diameters, matching the corresponding fixing unit can realize the fixing of pre-buried pipelines of different diameters.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
