Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to an auxiliary fixing sleeve device. Background Technology

[0002] In building, municipal, and fire protection engineering, the pre-embedding of pipe sleeves is a crucial step in the process of pipelines passing through structural walls and floors. Traditional pipe sleeve fixing methods mainly rely on on-site welding, binding, or simple bracket support, which have the following problems: (1) Low positioning accuracy: The sleeve is prone to displacement, which makes it difficult to install pipelines later, and may even require drilling to fix it; (2) Low construction efficiency: It relies on manual adjustment, the procedures are complicated, and it affects the progress of civil engineering. (3) Poor stability: The sleeve is prone to displacement during concrete pouring, causing leakage or structural defects; (4) Insufficient durability: On-site welding damages the galvanized layer, reduces the durability of the bracket, and the fixed bracket cannot be reused.

[0003] In existing technologies, some prefabricated supports suffer from problems such as poor turnover, high cost, complex installation, and inconvenient disassembly. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model proposes an auxiliary fixed sleeve positioning platform device to solve the problems of poor turnover and inconvenient installation and dismantling of prefabricated supports used for sleeve pre-embedding in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: An auxiliary sleeve positioning platform device includes a positioning bracket and a sleeve clamp mounted on the positioning bracket. The positioning bracket has a positioning hole for the sleeve to pass through, and the sleeve clamp is detachably connected to the positioning bracket and positioned directly opposite the positioning hole. This invention uses the positioning bracket to assist in positioning the sleeve, and the sleeve clamp to fix the sleeve in the corresponding position. Furthermore, the sleeve clamp allows for quick and easy connection and removal of the sleeve, making positioning faster and more convenient, and facilitating the reusability of this auxiliary sleeve positioning platform device.

[0006] Furthermore, the sleeve clamp includes a fixed clamping plate and several support plates symmetrically and movably arranged below the fixed clamping plate. The fixed clamping plate is provided with a tensioning drive mechanism for driving the support plates to move towards or away from each other.

[0007] Furthermore, the tensioning drive mechanism includes a limiting sleeve fixedly disposed on the lower side of the fixed clamping plate, several moving rods that slide laterally through the limiting sleeve, and a drive assembly movably connected to the fixed clamping plate and used to drive the moving rods to move laterally. The several moving rods are symmetrically arranged and correspond one-to-one with the support plate, and the outer ends of the moving rods are fixed to the support plate; the outer side of the support plate is provided with anti-slip texture.

[0008] Furthermore, the drive assembly includes a vertical rod that passes through the fixed clamp and can move up and down, and a truncated cone disposed at the lower end of the vertical rod. The inclined surface of the truncated cone cooperates with the inner end of the moving rod so that the up and down movement of the vertical rod drives the lateral movement of the moving rod.

[0009] Furthermore, the inner end of the moving rod is detachably connected to an inclined plate block, the inclined surface of which slides in conjunction with the inclined surface of the truncated cone; a return spring is provided between the inclined plate block and the limiting sleeve, and the return spring is sleeved on the moving rod.

[0010] Furthermore, the vertical rod is a long screw rod that is threadedly connected to the fixed clamping plate, and a locking nut is provided on the long screw rod.

[0011] Furthermore, the moving rod is a square tube, and the limiting sleeve is provided with a square hole for the square tube to move through; or the moving rod is a round rod, and the limiting sleeve and the moving rod are provided with a matching slide bar and slide groove.

[0012] Furthermore, the limiting sleeve is evenly distributed with several horizontal cylinders through which the moving rod passes, and the horizontal cylinders are provided with square holes or sliding strips.

[0013] Furthermore, the positioning bracket includes a detachably connected fixing frame and a positioning plate, with the positioning hole disposed on the positioning plate; the fixing clamp is connected to the fixing frame.

[0014] Furthermore, the fixing clamp is bolted to the fixing frame; the fixing frame is a rectangular frame welded from angle steel; the positioning plate is connected to the fixing frame via a threaded rod.

[0015] The beneficial effects of this utility model are: 1. This utility model uses a sleeve clamp to enable quick installation, removal and replacement of sleeves, thus solving the drawbacks of rigid fixation in traditional supports; 2. This utility model adapts to the pre-embedding requirements of different standard layers (steel structure / concrete) by ensuring that the center hole distance between each adjacent sleeve is equal, and controls the positioning error within ±1mm. 3. This utility model uses a rigid positioning plate as a horizontal auxiliary positioning to limit the edge distance inside the well: firstly, it is more suitable for horizontal and vertical floor slabs and aluminum formwork; secondly, it is easy to assemble, and different professional molds can be freely adjusted and assembled according to different site environments.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 and Figure 2 As shown in Embodiment 1 of this utility model, an auxiliary fixing sleeve positioning platform device includes a positioning bracket and a sleeve clamp disposed on the positioning bracket. The positioning bracket has at least two layers, and one layer has positioning holes for the sleeve 6 to pass through, serving to position the sleeve. The sleeve clamp is detachably connected to the other layer of the positioning bracket and is positioned directly opposite the positioning holes, used to fix the sleeve 6 in the positioning holes, facilitating the pre-embedding of the sleeve. The spacing of the positioning holes is set as needed.

[0021] Furthermore, such as Figure 3 and Figure 4As shown, the sleeve clamp includes a fixed clamping plate 3 and several support plates 13 symmetrically and movably arranged below the fixed clamping plate 3. The support plates 13 can be arranged symmetrically in two, four, or rotationally symmetrically in three. In this embodiment, four support plates 13 are symmetrically arranged. The fixed clamping plate 3 is provided with a tightening drive mechanism for driving the support plates 13 to move towards or away from each other. The sleeve 6 is fitted onto the outside of the several support plates 13, and the tightening drive mechanism drives the support plates 13 to move outwards in opposite directions to tighten them, thereby fixing the sleeve 6. Furthermore, the outer side of the support plates 13 is provided with anti-slip textures to prevent slippage.

[0022] Example 2 differs from Example 1 in that, as Figure 4 As shown, the tensioning drive mechanism includes a limiting sleeve 11 fixedly disposed on the lower side of the fixed clamping plate 3, a plurality of movable rods 10 laterally sliding through the limiting sleeve 11, and a drive assembly movably connected to the fixed clamping plate 3. The drive assembly cooperates with the movable rods 10 inserted into the limiting sleeve 11 to drive the movable rods 10 to move laterally. The plurality of movable rods 10 are symmetrically arranged and correspond one-to-one with the support plate 13. The outer end of the movable rod 10 is fixed to the support plate 13, and the inner end cooperates with the drive assembly.

[0023] Specifically, the driving assembly includes a vertical rod 7 that passes through the fixed clamping plate 3 and can move up and down, and a truncated cone 8 disposed at the lower end of the vertical rod 7. The inclined surface of the truncated cone 8 engages with the inner end of the moving rod 10 so that the up-and-down movement of the vertical rod 7 drives the moving rod 10 to move laterally. In this embodiment, the large end of the truncated cone 8 faces upward and the small end faces downward, so that when the vertical rod 7 drives the truncated cone 8 to move downward, the moving rod 10 moves laterally outward to tighten the sleeve 6.

[0024] Example 3 differs from Example 2 in that, as Figure 4 As shown, the inner end of the moving rod 10 is detachably connected to an inclined plate block 12. The inclined plate block 12 has a vertical plane on one side near the moving rod 10 and an inclined surface on the other side. The inclined surface is in contact with and slides into the inclined surface of the truncated cone 8.

[0025] Furthermore, the inclined plate block 12 protrudes from the outer periphery of the moving rod 10, and a return spring 9 is provided between the inclined plate block 12 and the limiting sleeve 11. The return spring 9 is sleeved on the moving rod 10. The return spring 9 gives the moving rod 10 an inward force, so that when the sleeve clamp is removed from the sleeve 6, only the vertical rod 7 needs to be moved upward, and the moving rod 10 drives the support plate 13 to automatically move inward to release the sleeve 6.

[0026] In addition, in a preferred embodiment, the inner end of the moving rod 10 is threaded to one side of the vertical plane of the inclined plate block 12, so that the moving rod 10 can pass through the fixed sleeve 6 and then be connected to the inclined plate block 12.

[0027] Example 4 differs from Example 3 in that, as Figure 4 As shown, the vertical rod 7 is a long screw rod threadedly connected to the fixed clamping plate 3, and a locking nut is provided on the long screw rod. Rotating the long screw rod downwards also provides a self-locking effect. The locking nut clamps and locks the rod in place.

[0028] In a preferred embodiment, a limiting plate is provided at a suitable position on the portion of the vertical rod 7 located on the upper side of the fixed clamping plate 3 to prevent excessive downward displacement of the vertical rod 7 from causing the truncated cone to detach from the inclined plate block 12 at the inner end of the moving rod 10. Furthermore, the lower end of the vertical rod 7 is threadedly connected to the truncated cone, facilitating the installation of the vertical rod 7 on the fixed clamping plate 3.

[0029] Example 4 differs from Example 3 in that the moving rod 10 is a square tube, and the limiting sleeve 11 is provided with a square hole for the square tube to move through; or the moving rod 10 is a round rod, and the limiting sleeve 11 and the moving rod 10 are provided with a matching slide bar and slide groove.

[0030] In this embodiment, as Figure 4 As shown, the moving rod 10 is a round rod. The limiting sleeve 11 has several round holes evenly distributed, each corresponding to a moving rod 10. The limiting sleeve 11 has several horizontal cylindrical bodies evenly distributed for the moving rod 10 to pass through. One end of each horizontal cylindrical body is fixed to the outer circumference of the round hole, and the other end extends towards the support plate 13. The diameter of the round hole is larger than that of the moving rod 10. The horizontal cylindrical body has a stepped hole, including a large hole connected to the round hole and a small hole that slides with the moving rod 10. The junction of the large and small holes forms an annular stepped surface. One end of the return spring abuts against the inclined plate block 12, and the other end abuts against the annular stepped surface. Furthermore, the small hole has evenly distributed sliders extending along the length of the moving rod 10, and the moving rod 10 has grooves that slide with the sliders.

[0031] Example 5 differs from Example 2 in that, as Figure 1 and Figure 2 As shown, the positioning bracket includes a detachably connected fixing frame 2 and a positioning plate 1, with the fixing frame 2 located above the positioning plate 1. The positioning hole is provided on the positioning plate 1; the sleeve clamp is connected to the lower side of the fixing frame 2. In this embodiment, the fixing frame 2 is a rectangular frame with a rectangular outer contour, welded from angle steel.

[0032] Furthermore, such as Figure 2 As shown, the fixing clamp 3 is connected to the angle steel of the fixing frame 2 by bolts 4. A vertical rod 7 passes through the central gap of the fixing clamp 3 in the rectangular frame. The positioning plate 1 is connected to the angle steel of the fixing frame 2 by a vertical threaded rod 5. Nuts are tightened on both the bolts 4 and the threaded rod 5. Furthermore, by tightening the nuts at different heights on the threaded rod 5, the relative height between the positioning plate 1 and the fixing frame 2 is adjustable.

[0033] In a preferred embodiment, the positioning plate 1 is made of rigid plastic sheet, which is easy to cut and assemble.

[0034] Example 6: The usage process of this utility model is as follows: Step 1: Pre-installation preparation Based on the BIM detailed model, locate the support installation position and verify the wall edge distance and rebar spacing. Draw lines according to the length and width of the mold plastic plate at the preset positions on the drawings, ensuring that the horizontal deviation is ≤2mm / m.

[0035] Step 2: Sleeve Fixation The sleeve is inserted into the positioning hole of the positioning bracket, locked with a sleeve clamp, and the pipe opening is sealed after the verticality is corrected.

[0036] Step 3: Mold fixing Place the sleeve mold on the board according to the drawing position, so that the edge of the plastic board coincides with the preset wall position, and spot weld the steel bar to the sleeve to ensure that it is firm and reliable.

[0037] Step 4: Remove the mold Check the position of the sleeve within 24 hours after pouring, correct any deviations in time, and loosen the clamps and remove the mold after confirming that there are no errors.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
