Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a modular hoisting and rapid connection construction device for steel-concrete structures. Background Technology

[0002] Modular steel-concrete composite structures break down steel-concrete composite systems into several functionally independent modular units, combining the flexibility of steel structures with the durability of concrete structures. They also possess the advantages of high precision and high efficiency from factory production, significantly shortening on-site construction cycles and reducing environmental interference. Furthermore, modular design enables a combination of diversified and standardized spatial layouts, making them suitable for various types of buildings such as residences, hotels, and offices. In particular, they demonstrate low-carbon and high-efficiency development potential in the field of prefabricated buildings.

[0003] For example, patent application CN 114033047 A discloses a connector, a modular steel-concrete composite structure and a construction method. It provides a connector in which, when connecting two adjacent box-shaped steel pipes, after pouring concrete into the lower box-shaped steel pipe, the first connecting part of the connector is inserted into the concrete. After the concrete hardens, the upper box-shaped steel pipe is centered and fitted into the second connecting part of the connector. Concrete is then poured into the upper box-shaped steel pipe, thus achieving an effective connection between the two adjacent box-shaped steel pipes.

[0004] This patent uses connectors to connect the box-shaped steel pipes vertically and hoops to connect them horizontally. However, existing connection methods have poor stability. If the assembled structure needs to be hoisted and moved before grouting (to adjust for positional deviations), direct hoisting can easily lead to connection failure. In this case, either the connectors and hoops need to be removed, and each module needs to be hoisted and reassembled, or the entire assembled structure needs to be grouted and the concrete needs to solidify before hoisting. Both methods have significant drawbacks: the former requires repeated disassembly and assembly, which is cumbersome and time-consuming; the latter requires waiting for the concrete to solidify, significantly extending the construction period and resulting in poor overall practicality. Summary of the Invention

[0036] Example 1

[0037] Embodiments of the present invention provide a modular hoisting and rapid connection construction device for reinforced concrete structures, such as... Figures 1-14 As shown, the device includes several connectors 1, each connector 1 including a square through-tube 2, on which a positioning plate 3 is installed. The square through-tube 2 is installed inside a box-shaped steel pipe 6. Each connector 1 has a connection hole, and a hoisting and fixing component is installed in the connection hole. The hoisting and fixing component is used to connect the connectors 1 together. A connecting component is installed on the box-shaped steel pipe 6, which is used to connect the box-shaped steel pipe 6 and the connectors 1. The connecting component cooperates with the hoisting and fixing component.

[0038] Preferably, the square through-tube 2 is also provided with an annular protrusion 4, and a directional groove is also provided on one side wall of the square through-tube 2.

[0039] The working principle and beneficial effects of the above technical solution are as follows: The square through-tube 2 is inserted into the box-shaped steel pipe 6, the positioning plate 3 contacts the upper surface of the box-shaped steel pipe 6, and then the hoisting and fixing components are connected to different connection holes, so that several connecting parts 1 are connected; then the connecting components are installed on the box-shaped steel pipe 6, so that the box-shaped steel pipe 6 and the connecting parts 1 are connected; thus, several connecting parts 1 and several box-shaped steel pipes 6 are connected, and several modules can form a stable whole, after which hoisting or grouting can be carried out.

[0040] The hoisting and fixing components can quickly connect multiple connectors 1 to form a stable hoisting force unit, avoiding the problem of repeated disassembly and assembly caused by the scattered hoisting of modules; the connecting components make the connection strength between connector 1 and box-shaped steel pipe 6 stronger, preventing loosening during hoisting; through the cooperation of the hoisting and fixing components and the connecting components, the overall stable hoisting of the assembled structure can be achieved before grouting, avoiding the risk of connection failure, and there is no need to wait for the concrete to solidify, which significantly shortens the construction cycle and makes it more practical and economical.

[0041] The shape of a single module is as follows: Figure 2-3As shown, the structure 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. Short steel beams 7 are provided on the short side plate 5, and long steel beams 8 are provided on the long side plate. The two short steel beams 7 and the two short side plates 5 are spliced ​​to form a groove one, and the two steel beams 8 and the two long side plates form a groove two. A cage 10 is provided in both groove one and groove two. The cage 10 is a wire mesh cage. The above structure is only a simplified description of the structure of a single module. For details, please refer to the patent application with publication number CN 114033047 A. This application will not elaborate further.

[0042] Example 2

[0043] Based on the above embodiment 1, as follows Figure 1 , Figures 13-14 As shown, the hoisting and fixing assembly includes a hoisting plate 34, a hoisting ring 35 on the hoisting plate 34, and connecting holes symmetrically arranged on the positioning plate 3. Insert rods 37 are symmetrically fixed on the lower surface of the hoisting plate 34. Two insert rods 37 pass through the connecting holes on different positioning plates 3. A limiting long rod 36 and a limiting short rod 28 are fixedly arranged at the lower end of the insert rods 37. The limiting short rod 28 contacts the positioning plate 3, and the limiting long rod 36 cooperates with the connecting assembly.

[0044] The working principle and beneficial effects of the above technical solution are as follows: the insertion rod 37 is passed through the connecting holes on different positioning plates 3, and then the limiting short rod 28 is bent and contacted with the lower surface of the positioning plate 3. After that, the limiting long rod 36 is bent and connected to the connecting component. Thus, several positioning plates 3 form a stable structure, and the connection between the limiting long rod 36 and the connecting component makes several modules form a stable lifting force unit. Then the lifting ring 35 can be lifted (those skilled in the art or users can select one or more lifting rings 35 for lifting as needed). It is more convenient to use and more practical.

[0045] Example 3

[0046] Based on the above embodiment 2, as Figures 4-6 As shown, the connecting component includes a fixing block 14, which is fixedly installed inside the box-shaped steel pipe 6. An inclined support rod 13 is symmetrically fixedly installed on the lower surface of the fixing block 14. The support rod 13 is fixedly connected to the box-shaped steel pipe 6. A positioning block 12 is also symmetrically fixedly installed on the fixing block 14, and the positioning block 12 extends out of the box-shaped steel pipe 6.

[0047] Preferably, the upper surface of the fixing block 14 is symmetrically fixed with positioning protrusion 1 21 and positioning protrusion 22. The two positioning protrusions 1 21 are connected to form a horizontal line 1, and the two positioning protrusions 22 are connected to form a horizontal line 2. A gap is provided between the horizontal line 1 and the horizontal line 2, and the gap is used to set the square through tube 2.

[0048] The working principle and beneficial effects of the above technical solution are as follows: When the square through-tube 2 is inserted into the box-shaped steel pipe 6, the side wall of the square through-tube 2 will contact the upper surface of the fixing block 14, thereby restricting the movement of the square through-tube 2. At this time, the positioning plate 3 is in contact with the upper surface of the box-shaped steel pipe 6. Meanwhile, the side wall of the square through-tube 2 will be within the interval between horizontal line one and horizontal line two, preventing the square through-tube 2 from shaking, which significantly improves the structural stability and safety of the connector 1 after assembly with the box-shaped steel pipe 6.

[0049] Example 4

[0050] Based on Example 1, such as Figure 4 , Figures 7-8 As shown, a sliding groove is provided on one side wall of the box-shaped steel pipe 6, and a movable plate 9 is slidably installed in the sliding groove. The movable plate 9 cooperates with the square through pipe 2, and the movable plate 9 cooperates with the directional sliding groove. The movable plate 9 is symmetrically provided with mounting holes 11. An L-shaped connecting plate 16 is also symmetrically fixed on one side wall of the box-shaped steel pipe 6. The L-shaped connecting plate 16 is symmetrically provided with mounting holes 2 and 3. Four positioning holes 1 are provided on one side wall of the box-shaped steel pipe 6. The four positioning holes 1 are symmetrically arranged in pairs. Four positioning holes 2 are also provided on the square through pipe 2. The mounting holes 2, positioning holes 1 and 2 are aligned with each other. The mounting hole 3 is aligned with the mounting hole 11.

[0051] Preferably, a fixing rod 15 is inserted into the mounting hole 3 and the mounting hole 11, and a fixing rod 20 is inserted into the mounting hole 2, the positioning hole 1 and the positioning hole 2. A through groove 1 is symmetrically opened on the fixing rod 15, and a through groove 2 is opened on the fixing rod 20. A U-shaped limiting rod 17 is installed in the through groove 1 and the adjacent through groove 2.

[0052] The working principle and beneficial effects of the above technical solution are as follows: When the square through-tube 2 is inserted into the box-shaped steel pipe 6, the directional slide will push the moving plate 9 to move. As the square through-tube 2 gradually moves, the mounting hole 11 on the moving plate 9 will align with the mounting hole 3 on the L-shaped connecting plate 16 (at this time, the square through-tube 2 moves to the lowest point). Then, the fixing rod 15 is inserted into the mounting hole 11 and the mounting hole 3, and the fixing rod 20 is inserted into the mounting hole 2, the positioning hole 1 and the positioning hole 2. Then, the U-shaped limiting rod 17 is inserted into the through groove 1 and the through groove 2, thereby completing the limiting of the fixing rod 15, the fixing rod 20 and the moving plate 9. Through the cooperation of the directional slide and the moving plate 9, the horizontal movement of the square through-tube 2 can be restricted. In addition, by setting the fixing rod 15, the fixing rod 20 and the U-shaped limiting rod 17, the vertical movement of the square through-tube 2 can be restricted.

[0053] The alignment of mounting hole 11 and mounting hole 3 can guide the installer to move the square through pipe 2 into place. The high degree of fit of the entire structure allows for effective connection between the square through pipe 2 and the box-shaped steel pipe 6. The precise alignment of the holes enables installation visualization. Furthermore, the synergistic effect of multiple components significantly improves the connection strength and stability between the square through pipe 2 and the box-shaped steel pipe 6, thereby significantly enhancing the practicality and reliability of the construction device.

[0054] Example 5

[0055] Based on the above embodiment 4, such as Figures 7-9 As shown, a clamping box 18 is fixedly installed on one side of the two L-shaped connecting plates 16 that are far apart from each other. A sliding plate 24 is fixedly installed inside the clamping box 18. A clamping rod 23 is fixedly installed on the sliding plate 24. The clamping rod 23 slides out of the clamping box 18 and slides through the L-shaped connecting plate 16. A wedge block 19 is fixedly installed on the clamping rod 23. The wedge block 19 cooperates with the moving plate 9. A spring 25 is also fixedly installed on the sliding plate 24. The spring 25 is fixedly connected to the clamping box 18. Two U-shaped limiting rods 17 are symmetrically arranged vertically, and the U-shaped limiting rods 17 are detachably fixedly connected to the clamping box 18.

[0056] 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 block 19 to push the two wedge blocks 19 to move in opposite directions. The wedge 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 block 19 will be tightly clamped on the moving plate 9, forming a stable lateral clamping constraint, which significantly enhances the limiting effect on the moving plate 9. The U-shaped limiting rod 17 is detachably and fixedly connected to the clamping box 18, which can effectively limit the position of the U-shaped limiting rod 17, thereby effectively limiting the axial movement and circumferential rotation of the fixed rod 15 and the fixed rod 20, forming a dual stable system of "clamping and anti-displacement + positioning and locking".

[0057] Example 6

[0058] Based on the above embodiment 5, such as Figures 10-12 As shown, a snap-fit ​​plate 26 is also provided on the second fixing rod 20. The snap-fit ​​plate 26 has symmetrically opened round holes 27. The second fixing rod 20 passes through the round holes 27. The snap-fit ​​plate 26 is provided with an L-shaped groove 29. The positioning block 12 is set in an L-shape and cooperates with the L-shaped groove 29.

[0059] Preferably, a snap-fit ​​rod 32 is rotatably and through the snap-fit ​​plate 26, and a torsion spring 31 is provided at the through position of the snap-fit ​​rod 32 and the snap-fit ​​plate 26. A rotating block 30 is provided at one end of the snap-fit ​​rod 32, and a rectangular block 33 is fixedly provided at the other end of the snap-fit ​​rod 32. A mating groove 38 is also provided on the snap-fit ​​plate 26, and the limiting rod 36 is mated with the mating groove 38.

[0060] The working principle and beneficial effects of the above technical solution are as follows: Before installing the first fixing rod 15 and the second fixing rod 20, the L-shaped groove 29 on the snap-fit ​​plate 26 is matched with the positioning block 12. At this time, the round hole 27 is just aligned with the second mounting hole, the first positioning hole, and the second positioning hole. Then, the second fixing rod 20 is inserted into the round hole 27 (the rotating block 30 is rotated beforehand so that the torsion spring is stressed, that is, the longer side of the rectangular block 33 contacts the positioning plate 3). After that, the rotating block 30 is rotated. Under the cooperation of the rotational force and the torsion spring torque, the rotating block 30 drives the snap-fit ​​rod 3. 2. Rotation: The locking rod 32 drives the rectangular block 33 to rotate. The shorter side of the rectangular block 33 contacts the positioning plate 3, thereby creating a downward squeezing force on the positioning plate 3. This further limits the movement of the positioning plate 3 in the vertical direction. The limiting rod 36 is bent and embedded into the mating groove 38 of the locking plate 26, realizing the mechanical interlock between the hoisting fixing component and the connecting component, constructing a three-dimensional force network, greatly improving the structural stability and construction safety of the entire hoisting unit, and effectively avoiding risks such as loosening and displacement during hoisting.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
