Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly to a construction device for modular hoisting and rapid connection of steel-concrete structures. Background Technique

[0002] The modular steel-concrete structure disassembles the steel-concrete structure system into several modular units with independent functions, combines the flexibility of the steel structure and the durability of the concrete structure, and has the advantages of high precision and high efficiency in factory production. It can significantly shorten the on-site construction period and reduce environmental interference. At the same time, through modular design, the combination of diversification and standardization of space layout is realized, which is applicable to various types of buildings such as residential, hotel, and office buildings, and particularly shows low-carbon and high-efficiency development potential in the field of prefabricated buildings.

[0003] For example, the patent application with the publication number CN 114033047 A discloses a connecting piece, a modular steel-concrete composite structure and a construction method. It provides a connecting piece. When connecting two adjacent box-shaped steel pipes up and down, after pouring concrete into the lower box-shaped steel pipe, insert the first connecting part of the connecting piece into the concrete. After the concrete hardens, centeringly sleeve the upper box-shaped steel pipe onto the second connecting part of the connecting piece, and pour concrete into the upper box-shaped steel pipe to realize the effective connection of two adjacent box-shaped steel pipes up and down.

[0004] This patent realizes the connection of box-shaped steel pipes in the up-down direction through the connecting piece and completes the connection between box-shaped steel pipes in the left-right direction with the help of hoop plates. However, the existing connection method has poor stability. If it is necessary to hoist and move the spliced structure before grouting (such as adjusting the position deviation), direct hoisting is likely to cause connection failure; at this time, either remove the connecting piece and the hoop plate, hoist each module one by one and splice them again; or wait until the entire assembled structure is grouted and the concrete solidifies before hoisting. Both of these methods have obvious drawbacks: the former requires repeated disassembly and assembly, with cumbersome processes and time-consuming; the latter requires waiting for the concrete to solidify, significantly extending the construction period and having poor overall practicability.

[0022] Embodiment 1 An embodiment of the present invention provides a construction device for modular hoisting and rapid connection of a steel-concrete structure, as Figures 1-14 shown, including a plurality of connecting members 1. The connecting member 1 includes a square through pipe 2, on which a positioning plate 3 is installed. The square through pipe 2 is installed inside a box-shaped steel pipe 6. A connecting hole is provided on a plurality of connecting members 1, and a hoisting and fixing assembly is arranged in the connecting hole. The hoisting and fixing assembly is used to connect a plurality of connecting members 1. A connecting assembly is provided on the box-shaped steel pipe 6. The connecting assembly is used to connect the box-shaped steel pipe 6 and the connecting member 1, and the connecting assembly cooperates with the hoisting and fixing assembly.

[0023] Among them, preferably, an annular protrusion 4 is further provided on the square through pipe 2, and a directional sliding groove is also provided on one side wall of the square through pipe 2.

[0024] The working principle and beneficial effects of the above technical solution are as follows: Insert the square through pipe 2 into the box-shaped steel pipe 6, the positioning plate 3 contacts the upper surface of the box-shaped steel pipe 6, and then connect the hoisting and fixing assembly to different connecting holes to connect a plurality of connecting members 1; then install the connecting assembly on the box-shaped steel pipe 6 to connect the box-shaped steel pipe 6 and the connecting member 1; thus, a plurality of connecting members 1 and a plurality of box-shaped steel pipes 6 form a connection, and a plurality of modules can form a stable whole, and then hoisting or grouting can be carried out; The hoisting and fixing assembly can quickly connect multiple connecting members 1 to form a stable hoisting stress unit, avoiding the problem of repeated disassembly and assembly caused by scattered hoisting of modules; the connecting assembly makes the connection strength between the connecting member 1 and the box-shaped steel pipe 6 stronger, preventing loosening during the hoisting process; through the cooperation of the hoisting and fixing assembly and the connecting assembly, the overall stable hoisting of the assembled structure can be realized before grouting, avoiding the risk of connection failure, and there is no need to wait for the concrete to solidify, significantly shortening the construction period, and having stronger practicability and economy.

[0025] Among them, the shape of a single module is as Figures 2-3As shown in the figure, it includes a short side plate 5 and a long side plate. The short side plate 5 is fixedly connected to two box-shaped steel pipes 6, and the long side plate is fixedly connected to two box-shaped steel pipes 6, thus forming a rectangular body. A short steel beam 7 is provided on the short side plate 5, and a long steel beam 8 is provided on the long side plate. Two short steel beams 7 and two short side plates 5 are spliced to form a first groove, and two steel beams 8 and two long side plates form a second groove. A cage 10, that is, a wire cage, is provided in both the first groove and the second groove. Among them, the above structure is only a simple description of the structure of a single module. For details, reference can be made to the patent application with the publication number CN 114033047 A, and this application will not elaborate further.

[0026] Embodiment 2 On the basis of the above Embodiment 1, as Figure 1 、 Figures 13-14 shown, the hoisting and fixing assembly includes a hoisting plate 34. A hoisting ring 35 is provided on the hoisting plate 34. Connecting holes are symmetrically arranged at the center of the positioning plate 3. Symmetrically fixed on the lower surface of the hoisting plate 34 are inserting rods 37. The two inserting rods 37 pass through the connecting holes on different positioning plates 3. Fixed at the lower ends of the inserting rods 37 are a limiting long rod 36 and a limiting short rod 28. The limiting short rod 28 contacts the positioning plate 3, and the limiting long rod 36 cooperates with the connecting assembly.

[0027] The working principle and beneficial effects of the above technical solution are as follows: Pass the inserting rods 37 through the connecting holes on different positioning plates 3, then bend the limiting short rod 28 to contact the lower surface of the positioning plate 3, and then bend the limiting long rod 36 to connect it with the connecting assembly. Thus, a stable structure is formed by several positioning plates 3, and the connection of the limiting long rod 36 with the connecting assembly makes several modules form a stable hoisting force-bearing unit. Then, the hoisting ring 35 can be hoisted (one or more hoisting rings 35 can be selected for hoisting according to the needs of those skilled in the art or users), which is more convenient to use and has stronger practicability.

[0028] Embodiment 3 On the basis of the above Embodiment 2, as Figures 4-6 shown, the connecting assembly includes a fixing block 14. The fixing block 14 is fixedly arranged inside the box-shaped steel pipe 6. Symmetrically fixed on the lower surface of the fixing block 14 are inclined struts 13, and the struts 13 are fixedly connected to the box-shaped steel pipe 6. Symmetrically fixed on the fixing block 14 are also positioning blocks 12, and the positioning blocks 12 fixedly extend out of the box-shaped steel pipe 6.

[0029] Among them, preferably, symmetrically fixed on the upper surface of the fixing block 14 are a first positioning protrusion 21 and a second positioning protrusion 22. A first horizontal line is formed by connecting between the two first positioning protrusions 21, and a second horizontal line is formed by connecting between the two second positioning protrusions 22. There is a gap between the first horizontal line and the second horizontal line, and the gap is used to arrange a square through pipe 2.

[0030] The working principle and beneficial effects of the above technical solution are as follows: When the square through pipe 2 is inserted into the box-shaped steel pipe 6, the side wall of the square through pipe 2 will contact the upper surface of the fixing block 14, thereby restricting the movement of the square through pipe 2. At this time, the positioning plate 3 just contacts the upper surface of the box-shaped steel pipe 6. At the same time, the side wall of the square through pipe 2 will be within the interval between the first horizontal line and the second horizontal line, preventing the square through pipe 2 from shaking, and significantly improving the structural stability and safety after the connector 1 and the box-shaped steel pipe 6 are assembled.

[0031] Embodiment 4 Based on Embodiment 1, as Figure 4 、 Figures 7-8 shown, a sliding groove is opened on one side wall of the box-shaped steel pipe 6. A moving plate 9 is slidably arranged in the sliding groove. The moving plate 9 is matched with the square through pipe 2 and is also matched with the directional sliding groove. Mounting holes one 11 are symmetrically arranged on the moving plate 9. L-shaped connecting plates 16 are symmetrically fixed on one side wall of the box-shaped steel pipe 6. Mounting holes two and three are symmetrically arranged on the L-shaped connecting plates 16. Four positioning holes one are opened on one side wall of the box-shaped steel pipe 6, and the four positioning holes one are symmetrically arranged in pairs. Four positioning holes two are also opened on the square through pipe 2. The mounting holes two, the positioning holes one, and the positioning holes two are aligned, and the mounting holes three are aligned with the mounting holes one 11.

[0032] Among them, preferably, a fixing rod one 15 is inserted into the mounting holes three and the mounting holes one 11, and a fixing rod two 20 is inserted into the mounting holes two, the positioning holes one, and the positioning holes two. Through grooves one are symmetrically opened on the fixing rod one 15, and a through groove two is opened on the fixing rod two 20. A U-shaped limiting rod 17 is installed in the through groove one and the adjacent through groove two.

[0033] The working principle and beneficial effects of the above technical solution are as follows: When the square through pipe 2 is inserted into the box-shaped steel pipe 6, the directional sliding groove will push the moving plate 9 to move. As the square through pipe 2 gradually moves, the mounting holes one 11 on the moving plate 9 will be aligned with the mounting holes three on the L-shaped connecting plate 16 (at this time, the square through pipe 2 moves to the lowest point). Then, a fixing rod one 15 is inserted into the mounting holes one 11 and the mounting holes three, and a fixing rod two 20 is inserted into the mounting holes two, the positioning holes one, and the positioning holes two. Then, the U-shaped limiting rod 17 is inserted into the through groove one and the through groove two, thereby completing the limitation of the fixing rod one 15, the fixing rod two 20, and the moving plate 9. Through the cooperation of the directional sliding groove and the moving plate 9, the movement of the square through pipe 2 in the horizontal direction can be restricted. In addition, by setting the fixing rod one 15, the fixing rod two 20, and the U-shaped limiting rod 17, the movement of the square through pipe 2 in the vertical direction can be restricted. The alignment between the first mounting hole 11 and the third mounting hole can prompt the installer that the square through tube 2 has been moved into place. The overall structure has a high degree of fit and can effectively connect the square through tube 2 and the box-shaped steel pipe 6. Visual installation is achieved through precise hole alignment, and through the coordinated action of multiple components, the connection strength and stability between the square through tube 2 and the box-shaped steel pipe 6 are greatly improved, significantly enhancing the practicability and reliability of the construction device.

[0034] Embodiment 5 Based on the above-mentioned Embodiment 4, as Figures 7-9 shown, on the sides of the two L-shaped connecting plates 16 away from each other, a clamping box 18 is fixedly arranged. Inside the clamping box 18, a sliding plate 24 is fixedly arranged. On the sliding plate 24, a clamping rod 23 is fixedly arranged. The clamping rod 23 extends out of the clamping box 18 slidably, and the clamping rod 23 passes through the L-shaped connecting plate 16 slidably. On the clamping rod 23, a wedge-shaped block 19 is fixedly arranged. The wedge-shaped block 19 cooperates with the moving plate 9. On the sliding plate 24, a spring 25 is also fixedly arranged, and the spring 25 is fixedly connected to the clamping box 18. The two U-shaped limiting rods 17 are arranged symmetrically up and down, and the U-shaped limiting rod 17 is detachably and fixedly connected to the clamping box 18.

[0035] The working principle and beneficial effects of the above technical solution are as follows: When the moving plate 9 moves, the moving plate 9 will cooperate with the wedge-shaped block 19 to push the two wedge-shaped blocks 19 to move in opposite directions. The wedge-shaped block 19 drives the clamping rod 23 to move, and the clamping rod 23 drives the sliding plate 24 to move. Under the action of the spring 25, the wedge-shaped block 19 will tightly clamp on the moving plate 9, forming a stable lateral clamping constraint, significantly enhancing the limiting effect on the moving plate 9. And through the detachable and fixed connection between the U-shaped limiting rod 17 and the clamping box 18, the position of the U-shaped limiting rod 17 can be effectively restricted, and further, the axial movement and circumferential rotation of the first fixing rod 15 and the second fixing rod 20 can be effectively restricted, forming a double stable system of "clamping to prevent displacement + positioning and locking".

[0036] Embodiment 6 Based on the above-mentioned Embodiment 5, as Figures 10-12 shown, a clamping plate 26 is further arranged on the second fixing rod 20. Circular holes 27 are symmetrically formed on the clamping plate 26. The second fixing rod 20 passes through the circular holes 27. An L-shaped groove 29 is arranged on the clamping plate 26. The positioning block 12 is L-shaped, and the positioning block 12 cooperates with the L-shaped groove 29.

[0037] Among them, preferably, a clamping rod 32 is rotatably penetrated through the clamping plate 26. A torsion spring 31 is arranged at the penetrating position of the clamping rod 32 and the clamping plate 26. One end of the clamping rod 32 is provided with a rotating block 30, and the other end of the clamping rod 32 is fixedly provided with a rectangular block 33. A matching groove 38 is further formed on the clamping plate 26, and the limiting long rod 36 cooperates with the matching groove 38.

[0038] The working principle and beneficial effects of the above technical solution are as follows: Before installing the first fixed rod 15 and the second fixed rod 20, the L-shaped groove 29 on the clamping plate 26 is fitted with the positioning block 12. At this time, the circular hole 27 just aligns with the second installation hole, the first positioning hole, and the second positioning hole. Then, the second fixed rod 20 is inserted into the circular hole 27. (Previously rotate the rotating block 30 so that the torsion spring is stressed, that is, the longer side of the rectangular block 33 contacts the positioning plate 3). After that, rotate the rotating block 30. Under the cooperation of the rotating force and the torsion force of the torsion spring, the rotating block 30 drives the clamping rod 32 to rotate, the clamping rod 32 drives the rectangular block 33 to rotate, and the shorter side of the rectangular block 33 contacts the positioning plate 3, thereby forming a downward extrusion force on the positioning plate 3; thus further restricting the movement of the positioning plate 3 in the vertical direction; Bend the limiting long rod 36 and embed it into the fitting groove 38 of the clamping plate 26 to achieve the mechanical interlock between the hoisting and fixing assembly and the connecting assembly, construct a three-dimensional stress network, greatly improve the structural stability and construction safety of the entire hoisting unit, and effectively avoid risks such as loosening and displacement during the hoisting process.

[0039] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
