Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a positioning device for preventing concrete blockage of PVC pipelines in building construction. Background Technology

[0002] In the water and electricity installation phase of building construction, the construction quality of pre-buried pipelines is crucial, directly affecting the smooth progress of subsequent decoration work and the long-term stable operation of the water and electricity system. Pre-buried pipelines need precise positioning to ensure their location within the building structure meets design requirements, providing a reliable foundation for subsequent equipment installation and wiring connections. Current methods for positioning pre-buried pipelines often rely on manual measurement and marking, followed by simple brackets for fixing. This method is highly susceptible to variations in manual skill levels, easily leading to poor positioning accuracy and pipeline deviations from design standards. Furthermore, during subsequent construction, the lack of effective fixing and protection makes pipelines prone to shifting. Once this occurs, adjustments are extremely difficult, not only delaying construction but also potentially causing unnecessary damage to the building structure. More importantly, during concrete pouring, concrete debris can easily seep into the pre-buried pipelines, causing blockages. Blockages require significant manpower, resources, and time for unblocking, increasing construction costs, and may even affect the normal operation of the water and electricity system if the unblocking is incomplete. Therefore, this utility model proposes a PVC pipeline anti-concrete sealing protection and positioning device for building construction projects. Utility Model Content

[0003] The purpose of this invention is to address the problem in the prior art where the lack of effective fixing and protection of pipelines makes them prone to displacement. Once this occurs, subsequent adjustments are extremely difficult, not only delaying construction progress but also potentially causing unnecessary damage to the building structure. More importantly, during the pouring of floor slab concrete, concrete debris can easily seep into the embedded pipelines, causing blockages. After pipeline blockage, subsequent unblocking work not only consumes a significant amount of manpower, resources, and time, increasing construction costs, but may also affect the normal operation of the water and electricity systems due to incomplete unblocking. This invention proposes a PVC pipeline anti-concrete blockage protection and positioning device for building construction projects.

[0004] The technical solution of this utility model is as follows: a PVC pipeline anti-concrete sealing protection and positioning device for building construction, comprising: a fixing strip, on which a groove is formed, and a slider is slidably disposed inside the groove; a threaded rod disposed at the upper end of the slider, the outer wall of which is threaded with a nut; a limiting component for pipeline fixing is fixedly disposed at the lower end of the slider; and supporting components for supporting the limiting component are disposed at both ends of the fixing strip.

[0005] Optionally, the limiting component includes a fixed cylinder fixedly disposed at the lower end of the slider, a set of bolts being threaded through the outer wall of the fixed cylinder, and a clamping block being rotatably disposed at the opposite end of the bolts.

[0006] Optionally, the support assembly includes a support frame fixedly disposed on the upper surfaces of both ends of the fixing strip, an adjusting bolt threaded through the support frame, and a rack rotatably connected to the lower end of the adjusting bolt.

[0007] Optionally, the support assembly further includes limiting rods fixedly disposed at both ends of the fixing bar. The outer walls of the limiting rods are respectively sleeved with half gears, which mesh with the rack. The outer walls of the half gears are fixedly disposed with support rods, and one end of the support rods is fixedly disposed with a locking block.

[0008] Optionally, a handle is fixedly provided on the upper surface of the fixing strip.

[0009] Optionally, the clamping block is configured with an arc-shaped structure.

[0010] Optionally, the support frame is configured with an "L" shaped structure.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model uses a limiting component consisting of a fixed cylinder, bolts, and an arc-shaped clamp to securely clamp PVC pipelines, achieving precise fixation of the pipelines and effectively preventing pipeline displacement caused by external force collisions during construction. This ensures that the pipeline position meets design standards. At the same time, the arc-shaped clamp fits tightly against the outer wall of the pipeline, reducing the gap between the pipeline and the limiting component and lowering the risk of concrete debris entering the pipeline and causing blockage.

[0013] Furthermore, this utility model, through a support assembly consisting of a support frame, adjusting bolt, rack, limiting rod, half gear, support rod, and locking block, combined with the sliding groove and slider structure on the fixing strip, can flexibly adjust the position of the limiting assembly according to construction needs, thereby achieving positioning and fixing of pipelines at different intervals. It can also adjust the rack by moving the adjusting bolt, causing the half gear to rotate and thus adjusting the support angle of the support rod, enhancing the overall stability of the device and preventing shaking or displacement during construction processes such as concrete pouring. This further ensures the accuracy and safety of pipeline positioning and reduces the difficulty and cost of subsequent adjustments. Attached Figure Description

[0028] Example

[0029] like Figure 1 and Figure 2 As shown, the present invention proposes a PVC pipeline anti-concrete sealing protection positioning device for building construction, comprising: a fixing strip 1, a handle 8 fixedly provided on the upper surface of the fixing strip 1 for easy removal of the device by the handle 8, a sliding groove 2 provided on the fixing strip 1, and a slider 3 slidably provided inside the sliding groove 2, which enables the slider 3 to slide stably according to the direction of the sliding groove 2.

[0030] Furthermore, a threaded rod 4 is provided at the upper end of the slider 3, and a nut 5 is threaded onto the outer wall of the threaded rod 4, which can be used to adjust the slider 3.

[0031] like Figure 2 and Figure 3 As shown, a limiting component 6 for fixing pipelines is fixedly installed at the lower end of the slider 3. The limiting component 6 includes a fixing cylinder 61 fixedly installed at the lower end of the slider 3. A set of bolts 62 are threaded through the outer wall of the fixing cylinder 61, and the bolts 62 are symmetrically arranged. The opposite ends of the bolts 62 are rotatably provided with clamping blocks 63 through bearings. The clamping blocks 63 are arc-shaped structures that can stably limit PVC pipelines of different thicknesses.

[0032] like Figure 1 and Figure 4 As shown, the two ends of the fixing strip 1 are provided with support components 7 for supporting the limiting component 6. The support component 7 includes a support frame 71 fixedly installed on the upper surface of both ends of the fixing strip 1. The support frame 71 is an "L" shaped structure. An adjusting bolt 72 is threaded through the support frame 71. The lower end of the adjusting bolt 72 is rotatably connected to a rack 73 through a bearing. The position of the rack 73 can be adjusted by rotating the adjusting bolt 72.

[0033] Furthermore, the support assembly 7 also includes limiting rods 74 fixedly installed at both ends of the fixing strip 1. Half gears 75 are respectively sleeved on the outer wall of the limiting rods 74, which can make the half gears 75 rotate stably on the limiting rods 74. The half gears 75 are meshed with the rack 73, so that the rack 73 drives the half gears 75 to rotate simultaneously. A support rod 76 is fixedly installed on the outer wall of the half gears 75. A locking block 77 is fixedly installed at one end of the support rod 76. The locking block 77 is an arc-shaped structure that can be locked with the roof steel bars, thereby providing stable support for the PVC pipeline.

[0034] The working principle of this embodiment is as follows: First, push the slider 3 to slide in the groove 2 so that each limiting component 6 is accurately aligned with the PVC pipeline to be fixed. Then tighten the nut 5 on the threaded rod 4 to firmly lock the slider 3 on the fixing strip 1, complete the initial position calibration, and meet the positioning requirements of pipelines with different spacing.

[0035] Subsequently, the PVC pipeline is placed inside the fixing cylinder 61, and the bolt 62 on the outer wall of the fixing cylinder 61 is rotated, causing the arc-shaped clamp 63 to move towards the pipeline. Because the clamp 63 has an arc-shaped structure, it can fit tightly against the outer wall of the pipeline. As the bolt 62 is continuously tightened, the clamp 63 firmly clamps the pipeline, which not only effectively avoids pipeline displacement caused by external force collisions and ensures that the position meets the design standards, but also minimizes the gap between the clamp 63 and the pipeline, reducing the risk of concrete debris entering the pipeline and causing blockage from the source.

[0036] After the pipeline is secured, rotate the adjusting bolt 72 on the support frame 71 to move the rack 73 vertically. Since the rack 73 meshes with the half-gear 75, the movement of the rack 73 will cause the half-gear 75 to rotate around the limiting rod 74, thereby adjusting the support angle of the support rod 76. Depending on the ground conditions at the construction site, rotate the support rod 76 to a suitable angle so that the lower locking block 77 is firmly secured to the reinforcing steel, providing stable support for the PVC pipeline.

[0037] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
