Description

Technical Field

[0001] This utility model relates to the field of prefabricated buildings, and in particular to a prefabricated building construction support. Background Technology

[0002] Prefabricated construction, as a modern construction method, is gradually gaining widespread attention in the construction industry. During the construction of prefabricated buildings, construction support bases, as key auxiliary components, play an indispensable role. Construction support bases are mainly used to provide stable support and fixation for prefabricated components during construction, ensuring the stability of the components during installation and construction, preventing displacement or overturning of components due to external forces, thereby guaranteeing construction quality and safety.

[0003] In existing prefabricated building construction support technologies, such as the patent document CN222614182U entitled "A Prefabricated Building Support," a novel support structure is provided. This support includes a base plate, a top plate, and several sets of anchoring units. Each anchoring unit consists of a vertical anchor rod and two arc-shaped racks. The anchor rod penetrates through the top and bottom plates, and the arc-shaped racks on both sides mesh with the straight racks of the anchor rod. The downward movement of the anchor rod causes the arc-shaped racks to rotate and insert into the soil, thus forming an anchor. This solution aims to resolve the contradiction between anchoring force and pull-out force during dismantling, improving the anchoring force to a certain extent and facilitating dismantling.

[0004] However, this existing technology still has some drawbacks. In actual use, a straight toothed rack is fixed to each of the left and right sides of the anchor rod. When the anchor rod moves downward, the two straight toothed racks mesh with the arc-shaped toothed rack on the same side, causing the arc-shaped toothed rack to rotate and thus insert into the soil along a circular trajectory. Although this design can achieve anchoring of the anchor rod and arc-shaped toothed rack into the soil, the soil will embed itself into the straight and arc-shaped toothed racks, which will affect the meshing process of the straight and arc-shaped toothed racks when lifting. When it is necessary to remove the support, due to the embedded soil, the meshing between the straight and arc-shaped toothed racks may become stuck or uneven, resulting in increased force required to pull out the anchor rod, increasing the difficulty and time cost of removal, and reducing construction efficiency.

[0005] In conclusion, it is particularly urgent to develop a new construction support technology that can effectively solve the problem of soil embedding affecting pull-out and optimize the anchoring and dismantling process. Utility Model Content

[0006] The present invention aims to provide a prefabricated building construction support to overcome the shortcomings mentioned above.

[0007] In order to achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A prefabricated building construction support, comprising:

[0009] A base plate and a top plate arranged horizontally, the top plate being supported above the base plate; and

[0010] A plurality of anchoring components are arranged in a matrix along a horizontal direction. Each anchoring component includes a support base, a worm, multiple worm wheels, and multiple anchoring plates. The support base is fixedly installed on the top surface of the base plate and has the worm and worm wheels rotatably connected inside it. The worm is arranged vertically, and the multiple worm wheels are located around the worm and mesh with it. One end of each anchoring plate is fixedly connected to the rotation axis of the multiple worm wheels. The other end of each anchoring plate is movable between a first position and a second position. In the first position, the other end of the anchoring plate is located above the base plate. In the second position, the other end of the anchoring plate passes through the base plate and is anchored to the soil.

[0011] Furthermore, the anchor plate includes:

[0012] A connecting arm, one end of which is fixedly connected to the rotating shaft of the worm gear; and

[0013] An arc-shaped cutting tooth is integrally formed with the other end of the connecting arm. The center of the arc-shaped cutting tooth coincides with the rotation axis of the worm gear. A through hole is provided on the base plate, and the arc-shaped cutting tooth selectively penetrates the through hole.

[0014] Furthermore, the edge of the arc-shaped cutter teeth near the worm gear rotation shaft is provided with several reverse teeth.

[0015] Furthermore, a telescopic rod is coaxially and fixedly connected to the upper part of the worm gear through the support base, and the upper end of the telescopic rod passes through the top plate and is detachably connected to an operating handwheel.

[0016] Furthermore, the telescopic rod includes:

[0017] A sleeve is fixedly connected at its lower end to the upper part of the worm gear;

[0018] The lower end of the connecting rod is slidably inserted into the sleeve, and the upper end of the connecting rod passes through the top plate and is detachably connected to the operating handwheel.

[0019] Furthermore, the sidewall of the sleeve is provided with strip-shaped holes in the vertical direction, and the lower end of the connecting rod is vertically fixedly connected with a sliding pin, which is slidably connected to the strip-shaped holes;

[0020] The upper end of the connecting rod is provided with a connecting part, the inner side of the operating handwheel is adapted to the connecting part, the connecting part is a polygonal prism structure, the connecting part movably passes through the operating handwheel and is connected to a fastener.

[0021] Furthermore, a first connecting ring is fixedly connected to the side wall of the connecting rod located above the sleeve, and a second connecting ring is provided on the lower surface of the top plate. The first connecting ring and the second connecting ring are connected by a connecting rope.

[0022] Furthermore, the top plate is provided with a number of operating holes, and each operating hole is provided in a corresponding manner to a connecting rope.

[0023] Furthermore, a number of bolts are fixedly connected to the base plate. The bolts are arranged vertically and in a matrix. The upper end of each bolt passes through the top plate, and two nuts are threadedly connected to the upper end of each bolt. The two nuts are located on the upper and lower sides of the top plate, respectively.

[0024] Compared with the prior art, this utility model has at least the following advantages:

[0025] (1) This utility model adopts a structural design of worm gear, worm wheel, and anchor plate. Both the worm and the worm are located above the base plate and do not come into contact with the soil during use. The soil is unlikely to penetrate the worm wheel and worm, reducing the impact on their meshing transmission. Compared with the prior art, the transmission structure of this utility model is located above the soil and has no direct contact with the soil, avoiding jamming and uneven operation during use.

[0026] (2) The anchor plate includes a connecting arm and an arc-shaped cutter tooth. The center of the arc-shaped cutter tooth coincides with the rotation axis of the worm wheel. When embedded in the soil, it can achieve stable anchoring through the rotation of the worm wheel. When dismantling, the worm wheel is driven by the reverse worm, so that the arc-shaped cutter tooth can be pulled out smoothly, which effectively avoids the influence of soil embedding on gear meshing and reduces the difficulty and time cost of dismantling.

[0027] (3) Several inverted teeth are provided near the edge of the rotating shaft. The inverted teeth are trapezoidal in shape, which makes the arc-shaped cutter teeth more firmly grip the soil when inserted into the soil, preventing them from being pulled out, thereby improving the anchoring force and ensuring the stability of the construction support during use.

[0034] 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.

[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Reference Figure 1-2 This utility model provides a prefabricated building construction support base, including a base plate 1, a top plate 2, and several anchoring components.

[0037] Both the base plate 1 and the top plate 2 are horizontally arranged rectangular steel plates. The top plate 2 is connected to the base plate 1 by several vertically arranged bolts 21. The bolts 21 are distributed in a matrix, with their upper ends penetrating the top plate 2. A nut 22 is screwed onto each of the upper and lower sides of the top plate 2 to adjust the height of the top plate 2 and keep it horizontal and stable to adapt to different ground conditions at different construction sites.

[0038] The anchoring components are distributed in a matrix along the horizontal direction between the bottom plate 1 and the top plate 2. Each anchoring component includes a support base 3, a worm 4, multiple worm wheels 5, and multiple anchoring plates.

[0039] The support base 3 is fixedly installed on the top surface of the base plate 1. Inside, a worm gear 4 and multiple worm wheels 5 are rotatably connected via bearings. The worm gear 4 is arranged vertically, and two worm wheels 5 are arranged around the periphery of each worm gear 4. The worm wheels 5 mesh with the worm gear 4. The rotation shaft of each worm wheel 5 is connected to the side wall of the support base 3 via bearings to ensure flexible rotation. The rotation shaft is fixedly connected to one end of the anchor plate. By rotating the worm gear 4, the worm wheels 5 can be rotated, thereby causing the other end of the anchor plate to flip.

[0040] The anchoring plate includes a connecting arm 6 and an arc-shaped cutter tooth 7. One end of the connecting arm 6 is fixed to the rotating shaft of the worm gear 5, and the other end is integrally formed with the arc-shaped cutter tooth 7. The center of the arc-shaped cutter tooth 7 coincides with the rotating shaft of the worm gear 5. Several inverted teeth 9 are provided on the edge of the arc-shaped cutter tooth 7 near the rotating shaft of the worm gear 5. The inverted teeth have a trapezoidal structure to enhance the grip. A through hole 8 is provided at the corresponding position on the base plate 1, through which the arc-shaped cutter tooth 7 selectively passes. The arc-shaped cutter tooth 7 can move between a first position and a second position. Initially and after use, the arc-shaped cutter tooth 7 is located in the first position, that is, above the base plate 1; when fixed to the soil, the arc-shaped cutter tooth 7 is located in the second position, which drives the worm gear 5 to rotate through the worm 4, so that the arc-shaped cutter tooth 7 passes through the through hole 8 and is anchored to the soil.

[0041] Reference Figure 2-3 To facilitate the rotation of the worm gear 4, the upper end of the worm gear 4 passes through the top of the support base 3 and is fixedly connected to the lower end of the telescopic rod. The telescopic rod includes a sleeve 11 and a connecting rod 13. The lower end of the sleeve 11 is fixedly connected to the worm gear 4, and the lower end of the connecting rod 13 is slidably inserted into the sleeve 11. A sliding pin 14 is fixedly connected to the side wall, and the sliding pin 14 cooperates with the slotted hole 12 on the side wall of the sleeve 11. The slotted hole 12 is set in the vertical direction, and the upper end of the connecting rod 13 passes through the top plate 2 and is connected to the operating handwheel 10.

[0042] Specifically, the upper end of the connecting rod 13 is provided with a connecting part 15. The connecting part 15 has a multi-prism structure and is adapted to the inner side of the operating handwheel 10. The connecting part 15 slides through the operating handwheel 10 in the vertical direction and is connected to a fastener 16. The fastener 16 is preferably a bolt 21 and a nut 22 to ensure a stable connection and easy disassembly and assembly.

[0043] In this invention, the connecting part 15 and the operating handwheel 10 are detachably connected, and the operating handwheel 10 is located above the top plate 2 for easy adjustment by the operator. When it is necessary to rotate the worm gear 4, the operating handwheel 10 only needs to be installed above the connecting rod 13. After adjustment, the operating handwheel 10 can be removed from above the connecting rod 13, and then the connecting rod 13 can be moved below the top plate 2 to facilitate the use of the support base during subsequent construction.

[0044] Combined with reference Figure 4To facilitate the operation of the connecting rod 13 as the height of the top plate 2 is adjusted, allowing it to pass through the top plate 2, a first connecting ring 17 is fixedly connected to the side wall of the connecting rod 13 located above the sleeve 11, and a second connecting ring 18 is fixedly connected to the lower surface of the top plate 2. The first connecting ring 17 and the second connecting ring 18 are connected by a connecting rope 19. This allows the connecting rod 13 to rise and fall synchronously with the top plate 2. The top plate 2 is provided with operating holes 20, each corresponding to a connecting rope 19. The operator can pass their hand through the operating hole 20 and use the connecting rope 19 to drive the connecting rod 13 upwards through the top plate 2, connecting it to the operating handwheel 10.

[0045] The working principle of this utility model:

[0046] In practice, construction workers first need to level the ground, place the base plate 1, and adjust the top plate 2 to be level according to the position of the precast components, then fine-tune by turning the nut 22. During anchoring, turning the operating handwheel 10 drives the worm gear 4 to rotate, and the anchoring plate rotates from the first position to the second position. The arc-shaped cutter teeth 7 cut into the soil, and the barbed teeth 9 prevent pull-out. Multiple sets of anchoring components work together to provide stable anchoring force. During dismantling, reverse the handwheel, and the anchoring plate is retracted. The operation is simple, and the support base 3 can be reused.

[0047] Understandably, in order to ensure that the bottom plate 1 arches upward during the anchoring process when the arc-shaped cutter teeth 7 cut into the soil, this utility model can install a pressure structure above the top plate 2 before anchoring, such as laying sandbags above the top plate 2 to increase the downward pressure on the bottom plate 1.

[0048] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
