Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and more particularly to an auxiliary installation structure for large-span assembled building prefabricated components and an installation method thereof. Background Art

[0002] A construction project refers to an engineering entity formed through the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities.

[0003] Currently, prefabricated buildings typically prefabricate some or all of their components in a factory and then transport them to the construction site for assembly. Once the prefabricated components arrive, reinforced concrete is spliced and poured to ensure the safety of the assembled building. The entire prefabricated component assembly process is complex and labor-intensive, resulting in low efficiency and reduced safety. The development of safer and more efficient auxiliary installation structures for prefabricated components is urgently needed.

[0004] For example, a prefabricated component auxiliary installation system for prefabricated buildings disclosed in publication number CN115387624A can reduce the time required to connect prefabricated components, improve the efficiency of connecting the entire prefabricated components, reduce connection errors caused by mistakes, and flexibly control the spacing and verticality of the entire prefabricated components through its unique positioning component and fine-tuning component. However, when using this solution, when assembling different prefabricated building walls, construction workers first need to fix the position of the walls so that the walls are on the same horizontal plane. In order to prevent the position of the walls from deviating during installation, construction workers need to use measuring tools to observe them. Construction workers need to use multiple connecting parts to fix the walls during installation. After installation, the walls may wobble due to loose installation of the connecting parts, which may lead to the wall being unstable when placed. The installation process is still relatively cumbersome, the workload of construction workers is relatively high, and the work efficiency of construction workers still needs to be improved.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example

[0037] In practice, when assembling different prefabricated building walls, the current conventional operation method is: construction workers first need to fix the position of the wall so that the walls are on the same horizontal plane. In order to prevent the position of the walls from deviating during installation, construction workers need to use measuring tools to observe them. Construction workers need to use a variety of connecting parts to fix the walls when installing them. After installation, the wall may shake due to the loose installation of the connecting parts, which may cause the wall to be unstable when placed. The installation process is relatively cumbersome, which not only consumes a lot of time of construction workers, but also increases the work intensity of construction workers and reduces the work efficiency of construction workers. The installation structure design of the present invention can effectively solve the problems existing in the prior art.

[0038] A large-span prefabricated building component auxiliary installation structure of this embodiment is combined with Figure 1-Figure 5 Shown, including:

[0039] The prefabricated component assembly includes a placement plate, an inner wall panel 2 is provided on the top of the placement plate 1, and outer wall panels 3 are provided on the front and rear sides of the inner wall panel 2;

[0040] The positioning mechanism is arranged above the placement plate 1 and located at the bottom of the inner wall panel 2 and the outer wall panel 3, and is used to clamp the inner wall panel 2 and the outer wall panel 3 inward from both sides;

[0041] The connecting mechanism is arranged at both ends of the top of the inner wall panel 2, and limiting units are respectively provided on both sides of the connecting mechanism, which are respectively engaged and connected with the outer wall panels 3 on both sides of the inner wall panel 2 through the limiting units.

[0042] As one of the optional positioning mechanism implementation methods in practice, combined with Figure 2As shown, the positioning mechanism includes two bases 4 provided at both ends of the top of the placement plate 1, each base 4 is provided with a fixed block 5 on the top, and the front and rear sides of the fixed block 5 are slidably connected to clamping blocks 6, which are connected to the translation force unit. The translation force unit is used to drive the clamping blocks 6 at both ends to move closer to or away from each other. More optimally, as Figure 1 As shown, a baffle 30 is fixedly connected to the side of the top of the placement plate 1, and the vertical cross-sectional area of the baffle 30 is larger than the vertical cross-sectional area of the clamping block 6.

[0043] Specifically, combined Figure 2 The translation force unit includes a cylinder 7 disposed in the inner cavity of the fixed block 5. One end of the cylinder 7 is fixedly connected to the rear clamping block 6, and the other end of the cylinder 7 is fixedly connected to a threaded tube 8. A spring 9 is sleeved on the surface of the cylinder 7. The two ends of the spring 9 are fixedly connected to the rear clamping block 6 and the threaded tube 8 respectively. The inner cavity of the threaded tube 8 is threadedly connected to a threaded rod 10. One end of the threaded rod 10 passes through the outer side of the front clamping block 6, and a handle 26 is provided at the end of the threaded rod 10. The inner cavity where the threaded tube 8 is located, that is, the top and bottom of the inner cavity of the fixed block 5 are both provided with axially extending limit grooves 28. The top and bottom of the threaded tube 8 are correspondingly provided with limit blocks 29 that slide in conjunction with the limit grooves 28. The cooperation of the limit grooves 28 and the limit blocks 29 limits the position of the threaded tube 8, making it less likely to rotate during movement.

[0044] To further enhance usability, the handle 26 is also provided with anti-slip grooves. The combination of the handle 26 and the anti-slip grooves increases the friction between the user's palm and the handle 26, facilitating the user's rotation of the threaded rod 10. Protective pads 27 are provided on the opposing inner walls of the two side clamping blocks 6. These pads can be rectangular and spaced apart. The provision of these pads protects the exterior wall panels 3, extending their service life. The top of one side of the clamping block 6 features a smooth bevel, which reduces manufacturing costs and reduces the financial burden on users.

[0045] As one of the embodiments of the connection mechanism, Figure 3As shown, in this embodiment, the connecting mechanism includes two shells 11 arranged at both ends of the top of the inner wall panel 2. Each shell 11 has an inner cavity in the middle. A movable block 13 is slidably connected to each side of the inner cavity of the shell 11. A telescopic power unit is provided in the inner cavity of the shell 11. The telescopic power unit is used to drive the movable blocks 13 on both sides to move away from or towards each other. Specifically, the bottom of the movable block 13 has a movable groove that slidably cooperates with the two side walls of the shell 11. The extension length of the movable groove is greater than the width of the corresponding side wall of the shell 11. This allows the movable blocks 13 on both sides to move closer to or away from each other and always maintain a sliding fit with the two side walls of the shell 11. Correspondingly, the wall surface of the outer wall panel 3 adjacent to the connecting mechanism is provided with a groove 32 that cooperates with the movable block 13, and the end of the movable block 13 is also provided with a limit unit. The side of the groove 32 is provided with a positioning groove 33 that engages with the limit unit. The limit unit is used to achieve a tight engagement between the two.

[0046] Specifically, combined Figure 4 and Figure 5 As shown, the limiting mechanism includes cavities 20 respectively opened on the inner side of the two ends of the movable block 13. A guide block 21 is slidably connected to each cavity 20. A spring 22 is connected to the inner side of the guide block 21. The other end of the spring 22 is connected to the inner wall of the cavity 20. A wedge block 23 is connected to the outer side of the guide block 21. One end of the wedge block 23 extends to the outer side of the movable block 13. A positioning groove 33 that cooperates with the wedge block 23 is correspondingly provided on the side of the groove 32 of the exterior wall panel 3. Through the coordinated use of the groove 32 and the positioning groove 33, when the movable block 13 and the wedge block 23 enter the inner cavity of the groove 32 and the positioning groove 33, the interior wall panel 2 and the exterior wall panel 3 can be connected, making it difficult for the two to separate.

[0047] Combine Figure 3As shown, as one of the optional embodiments, the telescopic power unit in this embodiment includes a dual-axis motor 14 disposed in the inner cavity of the housing 11. The two output shafts of the dual-axis motor 14 are fixedly connected to a threaded rod 15. The other end of the threaded rod 15 is rotatably connected to the inner wall of the housing 11. The surface of the threaded rod 15 is threadedly connected to a threaded block 16. The front and rear sides of the threaded block 16 are connected to a connecting piece 17. The inner cavity of the connecting piece 17 is rotatably connected to an adjustment block 18. The other end of the adjustment block 18 is rotatably connected to a connecting piece 2 19. The other end of the connecting piece 2 19 is connected to a square plate 12. The square plate 12 is located in the inner cavity of the housing 11 and is connected to the movable block 13. The bottom of the inner cavity of the housing 11 is provided with a slide 24 on both sides. The inner cavity of the slide 24 is slidably connected to a slider 25. The top of the slider 25 is fixedly connected to the bottom of the threaded block 16. The cooperation between the slide 24 and the slider 25 serves to limit the threaded block 16, thereby improving the stability of the threaded block 16 during movement. More specifically, in practice, a mounting seat 31 is provided on the surface of the dual-axis motor 14, and the housing 11 and the dual-axis motor 14 are detachably connected by bolts. The combination of the mounting seat 31 and the bolts can fix the dual-axis motor 14 and facilitate the user to disassemble it.

[0048] The above-mentioned auxiliary installation method of prefabricated components for large-span assembled buildings in this embodiment has the following process: when in use, the inner wall panels 2 and the outer wall panels 3 are placed on the top of the fixed block 5 of the positioning mechanism, and the bottom of the inner wall panels 2 and the outer wall panels 3 are first clamped using the clamping blocks 6 on both sides of the positioning mechanism; a connecting mechanism is set at both ends of the top of the inner wall panel 2, and the limiting mechanisms on both sides of the connecting mechanism are driven by the telescopic power unit to engage with the outer wall panel 3 accordingly, thereby realizing the connection and fixation of the top of the inner wall panel 2 and the outer wall panel 3.

[0049] Specifically, the user places the inner wall panel 2 and the outer wall panel 3 on the top of the fixed block 5, and then the user turns the handle 26, the handle 26 drives the threaded rod 10 to rotate, the threaded rod 10 will drive the threaded tube 8 to move when rotating, the threaded tube 8 drives the limit block 29 to slide in the inner cavity of the limit groove 28, the threaded tube 8 drives the cylinder 7 to move, the cylinder 7 drives the rear clamping block 6 to move, the rear clamping block 6 will compress the spring 19 when moving, as the threaded rod 10 continues to rotate, the threaded rod 10 will drive the front clamping block 6 to move, and then the two clamping blocks 6 will move relative to each other, so that the positions of the inner wall panel 2 and the outer wall panel 3 can be fixed, and then the user starts the dual-axis motor 14, the output shaft of the dual-axis motor 14 drives the threaded rod 2 15 to rotate, and the threaded rod 2 15 drives the two threaded blocks 16 to move relative to each other when rotating, and the threaded When block 16 moves, it will drive connecting piece 17 to move, and connecting piece 17 will drive one side of adjusting block 18 to move, so that the other side of adjusting block 18 will drive connecting piece 2 19 to move, and connecting piece 2 19 will drive square plate 12 to move, and square plate 12 will drive movable block 13 to move into the inner cavity of groove 32. When movable block 13 moves, wedge block 23 will contact with outer wall panel 3. As movable block 13 continues to move and the inclined surface set on the surface of wedge block 23 will make wedge block 23 move to the inner cavity of cavity 20, wedge block 23 drives guide block 21 to move, and guide block 21 drives spring 22 to be compressed. When movable block 13 moves to the specified position, the rebound force of spring 22 will make guide block 21 drive wedge block 23 to move into the inner cavity of positioning groove 33, so that inner wall panel 2 and outer wall panel 3 can be connected and installed.

[0050] The above is a schematic description of the present invention and its embodiments. This description is not restrictive and is only one embodiment of the present invention. Therefore, if a person skilled in the art is inspired by this description and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without creatively designing them, they shall fall within the scope of protection of the present invention.
