Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a replaceable pre-embedded positioning slot structure for building pipes. Background Technology

[0002] In building construction, pipe pre-embedding is a crucial step in ensuring building functionality. Traditional pre-embedding methods typically involve welding, binding, or one-time casting to fix the pipes, which has the following significant drawbacks:

[0003] Difficulty in positioning and adjustment: If the pipeline position is deviated during construction and needs to be adjusted, it is necessary to destroy the fixed steel bars or concrete structure, resulting in high rework costs and low efficiency.

[0004] Insufficient precision control: Manual positioning relies on experience, making it difficult to accurately control parameters such as pipe spacing and slope, which can easily lead to installation conflicts or functional problems later on.

[0005] Significant material waste: Traditional fasteners are mostly for single use and cannot be reused. Furthermore, subsequent maintenance requires the complete dismantling of the surrounding structure, resulting in resource waste.

[0006] Poor construction adaptability: It lacks a flexible adjustment mechanism for complex structures or multi-angle pipe pre-embedding scenarios, making it difficult to meet the diverse needs of modern buildings.

[0007] While some positioning devices exist in existing technologies, they generally suffer from problems such as limited adjustment methods, complex structures, or insufficient stability. There is still room for improvement, particularly in achieving multi-angle, high-precision positioning and rapid assembly / disassembly. Therefore, there is an urgent need for a modular, flexibly adjustable, stable, and replaceable pipeline pre-embedded positioning structure to address the pain points of traditional processes and improve construction efficiency and quality.

[0008] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0009] The purpose of this utility model is to address the shortcomings mentioned in the background art by proposing a replaceable pre-embedded positioning slot structure for building pipes.

[0010] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a replaceable building pipe pre-embedded positioning slot structure, including a strip plate, a support adjustment component, a sliding seat, a lateral position adjustment component, two slot positioning frames, two hollow shafts, an opening and closing adjustment component, and a quick-release fixing component.

[0011] The support adjustment assembly is located near both ends of the strip plate. The sliding seat is slidably mounted on the strip plate.

The opening and closing adjustment assembly is located on the sliding seat and connected to the two hollow shafts.

[0012] Preferably, the support adjustment assembly includes two universal balls, two support studs, two pads and two handwheels. Two spherical grooves are formed on the strip plate, and universal balls are movably installed in both spherical grooves. Support studs are threaded onto both universal balls, and handwheels and pads are fixedly installed at the top and bottom of the support studs, respectively.

[0013] Preferably, the lateral position adjustment assembly includes two support blocks, an adjusting screw, a guide rod, and an adjusting wheel.

The same adjusting screw is rotatably installed on the side of the two support blocks that are close to each other. The adjusting screw is threadedly connected to the sliding seat. An adjusting wheel is fixedly sleeved on the adjusting screw. The same guide rod that is slidably connected to the sliding seat is fixedly installed on the side of the two support blocks that are close to each other.

[0014] Preferably, the adjusting wheel has multiple screw holes centered on the adjusting screw, and a limit bolt is threadedly installed on the support block near the adjusting wheel, with one end of the limit bolt threaded into the corresponding screw hole.

[0015] Preferably, the quick-release fixing assembly includes four positioning square shafts and four rotating blocks.

[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] Reference Figure 1-6 A replaceable pre-embedded positioning slot structure for building pipes includes a strip plate 1, a sliding seat 2, two slot positioning frames 4 and two hollow shafts 3;

[0032] The sliding seat 2 is slidably installed on the strip plate 1. The bottom side of the sliding seat 2 is provided with an installation groove. The two hollow shafts 3 are rotatably installed in the installation groove and are arranged in parallel to each other. The two slot positioning frames 4 are symmetrically axially slidably installed with two positioning square shafts 41. Rotating blocks are fixedly installed on the four positioning square shafts 41. The end of the positioning square shaft 41 away from the rotating block is provided with an external thread. The two hollow shafts 3 are provided with internal threads in the middle position. The positioning square shafts 41 can be detachably installed in the corresponding hollow shafts 3 through the external and internal threads, which facilitates the disassembly and replacement of the slot positioning frames 4. At the same time, it is convenient to disconnect the embedded pipe and the slot positioning frames 4 from the sliding seat 2 and the hollow shafts 3 after they are poured into the concrete together.

[0033] Two spherical grooves are provided on the strip plate 1. Universal ball 11 is movably installed in each of the two spherical grooves. Support studs 12 are threaded on each of the two universal ball 11. Handwheels 14 and pads 13 are fixedly installed at the top and bottom of the support studs 12, respectively, which can provide effective support for the device and facilitate the adjustment of the pre-embedded depth of the pipes held by the two slot positioning frames 4 as needed.

[0034] Two symmetrically arranged support blocks 21 are fixedly installed on the top side of the strip plate 1. The same adjusting screw 22 is rotatably installed on the side of the two support blocks 21 that is close to each other. The adjusting screw 22 is threadedly connected to the sliding seat 2. An adjusting wheel 23 is fixedly sleeved on the adjusting screw 22. The same guide rod 24 that is slidably connected to the sliding seat 2 is fixedly installed on the side of the two support blocks 21 that is close to each other. This facilitates the control of the position of the sliding seat 2 on the strip plate 1, so as to facilitate the adjustment of the lateral position of the pre-embedded pipe according to actual needs. In order to limit the adjusting wheel 23 after the adjustment is completed and prevent the adjusting screw 22 from rotating due to external forces such as vibration during construction, multiple screw holes are opened on the adjusting wheel 23 with the adjusting screw 22 as the center. A limit bolt is threadedly installed on the support block 21 close to the adjusting wheel 23, and one end of the limit bolt is threaded into the corresponding screw hole.

[0035] A worm gear 32 is rotatably mounted on the sliding seat 2. The top end of the worm gear 32 extends above the sliding seat 2 and is fixedly mounted with a rotating wheel 33. Two hollow shafts 3 are each fixedly fitted with worm wheels 31. The worm gear 32 meshes with the two worm wheels 31, which can control the opening and closing of the two slot positioning frames 4 as needed, thereby facilitating the snap-fit ​​positioning operation of the embedded pipe that needs to be snap-fitted and positioned. In order to avoid the setting of the worm gear 32 affecting the lateral position adjustment of the sliding seat 2 along the strip plate 1, a guide opening is provided on the strip plate 1, and the worm gear 32 passes through the guide opening.

[0036] In this embodiment, in order to facilitate bending or cutting off the top side of the pre-embedded pipe and the slot positioning frame 4 after they are poured into the concrete and disconnected from the sliding seat 2 and the hollow shaft 3, and to improve the connection stability between the slot positioning frame 4 and the concrete after it is poured into the concrete, pre-bending grooves are provided on both the front and rear sides of the slot positioning frame 4, and positioning ribs 401 are inserted and installed on the slot positioning frame 4 and are arranged parallel to each other with the hollow shaft 3.

[0037] Working principle: In use, first determine the installation position and direction of the pre-embedded pipe according to the construction drawings. The strip plate 1 is fixed in the predetermined position by the cooperation of the pad plate 13, the support stud 12 and the handwheel 14. The height of the support stud 12 is adjusted by rotating the handwheel 14 so that the two slot positioning frames 4 are at the appropriate pre-embedded depth. Then, the limit bolt is loosened, and the adjusting wheel 23 is rotated to drive the adjusting screw 22 to rotate, so that the sliding seat 2 moves along the guide rod 24 to the design position. Then, the limit bolt is tightened to fix the adjusting wheel 23. Then, the worm gear 32 is driven to rotate by the rotating wheel 33, which drives the two worm wheels 31 to rotate synchronously, so that the two slot positioning frames 4 open to an appropriate angle. The pre-embedded pipe is placed into the slot of the slot positioning frame 4. The rotating wheel 33 is rotated in the opposite direction to close the slot positioning frame 4 and clamp the pipe.

[0038] After checking that all parts are securely connected, concrete pouring can begin. Once the concrete has initially set, rotate the rotating block to separate the positioning square shaft 41 from the hollow shaft 3, thus detaching the slot positioning frame 4 from the device. Finally, bend or cut the pre-bending groove as needed to form a complete pre-embedded pipeline system.

[0039] In the design of the adjusting screw 22, its pitch is preferably between 2mm and 5mm to ensure a balance between adjustment accuracy and adjustment speed. When the adjusting wheel 23 rotates one revolution, the sliding seat 2 moves a distance equal to one pitch along the guide rod 24, thereby achieving millimeter-level fine-tuning of the lateral position. This design effectively solves the problem of "difficulty in positioning and adjustment" mentioned in the background art, enabling construction personnel to accurately correct the position of the pre-embedded pipe without damaging the original structure.

[0040] The transmission ratio between the worm gear 31 and the worm 32 is set between 1:20 and 1:50, providing excellent self-locking performance. This ensures that the clamping positioning frame 4 will not shift due to external forces after clamping the pipe, thus improving the overall structural stability. The rotating wheel 33 features an anti-slip textured design, facilitating torque control. Operators can judge the clamping tightness by feel, avoiding over-tightening or loosening. This feature effectively solves the construction risks caused by insufficient precision control and unstable clamping in traditional processes.

[0041] The positioning square shaft 41 in the quick-release fixing assembly adopts a square cross-section structure, which is installed to fit into the square hole on the slot positioning frame 4 to prevent rotation during axial sliding. The end of the positioning square shaft 41 is provided with an M8 standard external thread, which matches the M8 internal thread machined inside the hollow shaft 3, with a screw depth of not less than 15mm, ensuring that the connection strength meets the stress requirements during concrete pouring. This structure enables quick separation between the slot positioning frame 4 and the hollow shaft 3, significantly improving the efficiency of subsequent maintenance and dismantling, reducing resource waste, and addressing the problem of "serious material waste" mentioned in the background art.

[0042] The pre-bending grooves on the front and rear sides of the card slot positioning frame 4 are V-shaped, with a groove depth of 1.5mm to 3mm, a width of 2mm to 4mm, and a spacing of 10mm to 20mm. This facilitates manual bending operations later without the need for specialized equipment. Simultaneously, these pre-bending grooves enhance the anchoring effect between the card slot positioning frame 4 and the concrete, improving the overall stability of the embedded structure and strengthening the ability to solve the "positioning instability" problem from a structural perspective.

[0043] The positioning rib 401 is made of stainless steel, with a diameter of 6mm to 8mm and a length that can be selected from 50mm to 200mm depending on the actual project requirements. It is inserted into the pre-drilled through hole at the top of the positioning bracket 4 to enhance the bond with the concrete and provide additional support points. This design not only improves the shear resistance of the embedded structure but also provides a standardized reference for subsequent processes, further enhancing construction accuracy.

[0044] In the support and adjustment assembly, the universal ball 11 is made of high-strength engineering plastic, which has good wear resistance and rotational flexibility. The gap between its spherical surface and the spherical groove on the strip plate 1 is controlled within 0.1mm, ensuring a smooth and reliable adjustment process. The support stud 12 adopts a trapezoidal thread structure with a pitch of 4mm. The handwheel 14 has a diameter of 100mm. The bottom of the pad plate 13 is equipped with an anti-slip rubber layer with an area of ​​100mm×100mm and a thickness of 5mm, ensuring that the device can be stably supported on different base surfaces (such as steel mesh, formwork, etc.), solving the problem of "poor construction adaptability" of traditional positioning devices.

[0045] The above provides a detailed description of a replaceable pre-embedded positioning slot structure for building pipes provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model.
