Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a self-leveling prefabricated ground-mounted module. Background Technology

[0002] In the field of ground engineering technology, self-leveling prefabricated elevated ground modules are building components used to achieve elevated ground installation and have automatic leveling functions. These modules separate the ground from the base layer through an elevated structure, forming an air insulation layer. At the same time, they solve the problem of unevenness in the base ground through a leveling mechanism. They are mainly used in scenarios such as computer rooms and factories that require elevated cabling or thermal insulation.

[0003] However, existing ground-based overhead modules have some shortcomings in practical applications:

[0004] On the one hand, traditional modules mostly adopt fixed support structures, and leveling relies on manual adjustment with shims or bolts, which is inefficient and lacks precision, making it difficult to adapt to the height difference of the base ground, resulting in poor flatness of the elevated ground.

[0005] On the other hand, the thermal insulation performance of elevated structures relies on a single panel and lacks a systematic thermal insulation design. Heat is easily conducted through the supporting frame, resulting in poor thermal insulation performance.

[0006] In addition, the connections between modules mostly use welding or complex bolt structures, which require precise positioning during installation, making construction difficult and time-consuming, and cannot meet the needs of rapid installation of prefabricated buildings. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a self-leveling prefabricated ground-mounted module, which overcomes the deficiencies of existing technologies and effectively solves the problems of poor flatness of raised ground, poor heat insulation effect, and inability to meet the needs of rapid installation of prefabricated buildings.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A self-leveling prefabricated ground-mounted module includes a fiber cement board. An array of overhead modules and an array of leveling modules are respectively arranged on the bottom of the fiber cement board. The overhead modules are distributed around the leveling modules. Each overhead module includes a rectangular frame and a thermal insulation board. The thermal insulation board is disposed on the inner wall of the rectangular frame, and both the rectangular frame and the thermal insulation board are attached to the bottom outer wall of the fiber cement board.

[0010] Preferably, the leveling module includes a top plate, a lead screw, a threaded sleeve, and a base. The top plate is disposed on the bottom outer wall of the rectangular frame, the lead screw is rotatably connected to the center of the bottom outer wall of the top plate, the threaded sleeve is screwed onto the outer wall of the lead screw, and the base is welded to the bottom outer wall of the threaded sleeve.

[0011] Preferably, the leveling module further includes equidistant limiting plates, which are welded to the top outer wall of the top plate.

[0012] Preferably, the leveling module further includes a positioning plate, which is welded to the top outer wall of the top plate, and limiting plates are distributed around the positioning plate.

[0013] Preferably, the leveling module further includes a top pressure plate and fastening bolts. The top pressure plate is disposed on the top outer wall of the positioning plate, and fastening bolts are installed between the positioning plate and the top pressure plate.

[0014] Preferably, a rectangular groove is provided on the inner wall of the rectangular frame, and the heat insulation board is provided on the inner wall of the rectangular groove.

[0015] Preferably, the rectangular frame has arc-shaped positioning grooves at all four corners, and the arc-shaped positioning grooves are attached to the outer wall of the positioning plate, and the limiting plate is located between the two rectangular frames.

[0016] Preferably, the rectangular frame has an arc-shaped groove at the top of the arc-shaped positioning groove at the four corners, and the top pressure plate is in close contact with the bottom inner wall of the arc-shaped groove.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The self-leveling prefabricated ground-mounted module designed in this paper can achieve rapid leveling through the cooperation of the lead screw and threaded sleeve of the leveling module. When the lead screw is rotated, the lead screw drives the top plate to move up and down, so that the fiber cement board can adapt to the undulation of the base ground, improve the leveling accuracy, and solve the problem of low efficiency of traditional manual leveling.

[0019] 2. The self-leveling prefabricated ground-mounted module of this design has a rectangular groove set in the inner wall of the rectangular frame of the elevated module, with embedded thermal insulation board to form a closed thermal insulation cavity, which can reduce the thermal conductivity coefficient. The thermal insulation board is tightly attached to the bottom of the fiber cement board, and with the surrounding elevated structure, the heat conduction is blocked, thus improving the overall thermal insulation performance.

[0020] 3. The self-leveling prefabricated ground-mounted module of this design uses a positioning plate of the leveling module to cooperate with the arc-shaped positioning groove of the rectangular frame to achieve rapid positioning between modules. The top pressure plate is fixed to the arc-shaped slot by fastening bolts, and the module connection can be completed without welding, which improves the installation efficiency. In addition, the limiting plate restricts the displacement of adjacent rectangular frames to ensure the stability of the prefabricated structure. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-5 Example 1: A self-leveling prefabricated ground-mounted module includes a fiber cement board 3. An array of overhead modules 1 and an array of leveling modules 2 are respectively arranged at the bottom of the fiber cement board 3. The overhead modules 1 are distributed around the leveling modules 2. The overhead module 1 includes a rectangular frame 11 and a thermal insulation board 12. The thermal insulation board 12 is disposed on the inner wall of the rectangular frame 11, and both the rectangular frame 11 and the thermal insulation board 12 are attached to the bottom outer wall of the fiber cement board 3. A rectangular groove 4 is provided on the inner wall of the rectangular frame 11, and the thermal insulation board 12 is disposed on the inner wall of the rectangular groove 4.

[0029] The basic structure of the self-leveling prefabricated ground-mounted module consists of fiber cement board 3, overhead module 1 and leveling module 2. The overhead module 1 is located around the leveling module 2 and consists of a rectangular frame 11 and a thermal insulation board 12. A rectangular groove 4 is opened in the inner wall of the rectangular frame 11. The thermal insulation board 12 is made of extruded polystyrene board and embedded in the rectangular groove 4. An arc-shaped positioning groove 5 is opened at the corner of the rectangular frame 11 for positioning with the leveling module 2.

[0030] In this embodiment, a rectangular groove 4 is provided on the inner wall of the rectangular frame 11 of the overhead module 1, and a heat insulation board 12 is embedded in it to form a closed heat insulation cavity, which can reduce the heat transfer coefficient. The heat insulation board 12 is tightly attached to the bottom of the fiber cement board 3, and together with the surrounding overhead structure, it blocks the conduction of heat and improves the overall heat insulation performance.

[0031] In embodiment 2, the leveling module 2 includes a top plate 21, a lead screw 22, a threaded sleeve 23, and a base 24. The top plate 21 is disposed on the bottom outer wall of the rectangular frame 11. The lead screw 22 is rotatably connected to the center of the bottom outer wall of the top plate 21. The threaded sleeve 23 is screwed onto the outer wall of the lead screw 22. The base 24 is welded to the bottom outer wall of the threaded sleeve 23. The leveling module 2 also includes equidistantly distributed limiting plates 26, which are welded to the top outer wall of the top plate 21. The leveling module 2 also includes a positioning plate 25, which is welded to the top outer wall of the top plate 21, and the limiting plates 26 are distributed around the periphery of the positioning plate 25. The leveling module 2 also includes a top pressure plate 27 and fastening bolts 28. The top pressure plate 27 is disposed on the top outer wall of the positioning plate 25, and fastening bolts 28 are installed between the positioning plate 25 and the top pressure plate 27.

[0032] The leveling module 2 consists of a top plate 21, a lead screw 22, a threaded sleeve 23, and a base 24. The base 24 is welded to the bottom of the threaded sleeve 23 and contacts the base surface. A positioning plate 25 is welded to the top of the top plate 21, and four limiting plates 26 are evenly distributed around it. A top pressure plate 27 is set above the positioning plate 25 and is connected to the positioning plate 25 by fastening bolts 28. The edge of the top pressure plate 27 is embedded in the arc-shaped slot 6 of the rectangular frame 11 to fix the module.

[0033] In this embodiment, by cooperating with the threaded sleeve 23 of the leveling module 2, rapid leveling can be achieved. When the threaded screw 22 is rotated, the threaded screw 22 drives the top plate 21 to move up and down, so that the fiber cement board 3 adapts to the undulations of the base surface, improving the leveling accuracy and solving the problem of low efficiency of traditional manual leveling.

[0034] In embodiment 3, each of the four corners of the rectangular frame 11 is provided with an arc-shaped positioning groove 5, and the arc-shaped positioning groove 5 is attached to the outer wall of the positioning plate 25. The limiting plate 26 is located between the two rectangular frames 11. At the top of the arc-shaped positioning groove 5, an arc-shaped slot 6 is provided at the four corners of the rectangular frame 11, and the top pressure plate 27 is tightly attached to the bottom inner wall of the arc-shaped slot 6.

[0035] During module assembly, the base 24 of the leveling module 2 is first placed on the base surface. The height of the top plate 21 is adjusted by rotating the screw 22 so that the top surface of the positioning plate 25 is aligned with the design elevation. Then, the arc-shaped positioning groove 5 of the rectangular frame 11 is attached to the outside of the positioning plate 25, and the limiting plate 26 is inserted into the gap between adjacent rectangular frames 11 to restrict lateral displacement. Finally, the fastening bolts 28 are tightened to press the top pressure plate 27 against the arc-shaped groove 6, completing the module fixation. Fiber cement board 3 is laid on top of the overhead module 1.

[0036] In this embodiment, the positioning plate 25 of the leveling module 2 cooperates with the arc-shaped positioning groove 5 of the rectangular frame 11 to achieve rapid positioning between modules. The top pressure plate 27 is fixed to the arc-shaped slot 6 by fastening bolts 28, and the module connection can be completed without welding, which improves the installation efficiency. In addition, the limiting plate 26 restricts the displacement of adjacent rectangular frames 11 to ensure the stability of the assembled structure.

[0037] Working principle: During module installation, first mark the position of the leveling module 2 on the base ground according to the design drawings, and fix the base 24 to the marked point. By rotating the lead screw 22, the top plate 21 is moved up and down to adjust the height of the top plate 21 so that the top surface of the positioning plate 25 reaches the design elevation, thus achieving initial leveling.

[0038] Next, the curved positioning groove 5 of the rectangular frame 11 is aligned with the positioning plate 25 and fitted together. The limiting plate 26 is used to perform lateral positioning of the adjacent rectangular frames 11 to ensure the array distribution accuracy of the overhead module 1. At this time, the thermal insulation board 12 is installed synchronously with the rectangular frame 11 to form an overhead thermal insulation layer.

[0039] Finally, the top pressure plate 27 is placed above the positioning plate 25, and the top pressure plate 27 is connected to the positioning plate 25 by fastening bolts 28. The edge of the top pressure plate 27 is close to the arc groove 6 of the rectangular frame 11, and the rectangular frame 11 is fixed on the leveling module 2. The fiber cement board 3 is laid on the top of the overhead module 1 to form a complete overhead ground.
