Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a composite plate hoisting structure for a multi-layer frame structure and a hoisting method thereof. Background Art

[0002] In recent years, composite panels have been widely used in prefabricated buildings due to their high production efficiency, convenient construction, and environmental protection. Conventional prefabricated steel frame structure composite panels are installed using a forward installation construction process, which has relatively high requirements for the stacking, transportation, and installation of site components. However, for projects with tight schedules, the frame structure is often constructed first, and the space inside the frame structure is small, which is not convenient for the transportation and lifting of composite panels within the frame structure. In addition, the traditional installation method uses multiple lifting points for installation, which is prone to cracking of the prefabricated base plate due to uneven force on the lifting points, making lifting difficult. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide a composite plate lifting structure and a lifting method for a multi-story frame structure. By setting a cantilever section of the transport track, it is convenient to lift the composite plates outside the frame structure and use a trolley to transport the composite plates into the frame structure, thereby avoiding the problem of narrow lifting space inside the frame structure.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a composite plate hoisting structure for a multi-layer frame structure, comprising:

[0005] A transport track, wherein the transport track is laid on the to-be-constructed layer of the multi-layer frame structure, and one end of the transport track extends out of the multi-layer frame structure to form a cantilever section;

[0006] A trolley for transporting the laminated panels, the trolley being slidably connected to the transport track;

[0007] A traction rope for towing the trolley to move, one end of the traction rope being connected to the trolley;

[0008] A lifting device for lifting the composite plate on the trolley is connected to a layer above the layer to be constructed.

[0009] A further improvement of the composite plate lifting structure for multi-story frame structure of the present invention is that it also includes a support assembly for supporting the cantilever section, including a support column arranged at the bottom of the cantilever section, one end of the support column is supported to the ground, and the other end is detachably connected to the cantilever section.

[0010] A further improvement of the composite plate lifting structure for multi-story frame structure of the present invention is that the support assembly also includes a steel cable, the top of the cantilever section is connected to a first cable buckle for connecting the steel cable, and the top of the multi-story frame structure is connected to a second cable buckle for connecting the steel cable, and when the steel cable is connected to the first cable buckle and the second cable buckle, the steel cable is in a taut state.

[0011] A further improvement of the composite plate lifting structure for multi-story frame structure of the present invention is that the transport track includes a base plate and two baffles vertically connected to both sides of the base plate, the two baffles are connected to guide slide grooves on their relative inner sides, and both sides of the trolley are connected to sliders corresponding to the guide slide grooves.

[0012] A further improvement of the composite plate hoisting structure for a multi-layer frame structure of the present invention is that the hoisting device comprises:

[0013] A rectangular hanging frame arranged in a horizontal direction, the rectangular hanging frame comprising two main beams arranged in parallel and spaced apart from each other and a plurality of secondary beams spaced apart and connected between the two main beams;

[0014] Two lifting ring groups respectively connected to the bottom of the two main beams, each of the lifting ring groups includes a plurality of lifting rings, the plurality of lifting rings are arranged at intervals along the length direction of the main beam, and the lifting rings in the two lifting ring groups correspond to each other one by one;

[0015] Two fixed pulley blocks are respectively arranged at the bottom of the two lifting ring groups, each of the fixed pulley blocks includes a plurality of fixed pulleys, and in each lifting ring group, except for the two outermost lifting rings, the bottoms of all the remaining lifting rings are connected to the fixed pulleys;

[0016] Two movable pulley blocks are respectively arranged at the bottom of the two fixed pulley blocks, each of the movable pulley blocks includes a plurality of movable pulleys, and the movable pulleys are staggered between two adjacent fixed pulleys in each fixed pulley block, and the bottom of each movable pulley is connected to a hook;

[0017] Two lifting ropes are respectively arranged at the bottom of the two main beams, and each of the lifting ropes is sequentially wound around all the fixed pulleys and movable pulleys in the corresponding fixed pulley group and the corresponding movable pulley group. The two ends of each lifting rope are respectively connected to the two outermost lifting rings. When the composite plate is hoisted, each movable pulley can realize adaptive movement relative to the lifting rope under the action of the gravity of the composite plate.

[0019] Step 1: Provide the above-mentioned composite plate hoisting structure for the multi-layer frame structure and install it in place;

[0034] The composite plate hoisting structure and hoisting method for a multi-story frame structure of the present invention are further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] See also Figure 1 to Figure 5 As shown, the composite plate hoisting structure for multi-story frame structure includes:

[0036] A transport track 1, wherein the transport track 1 is laid on the to-be-constructed layer of the multi-layer frame structure 7, and one end of the transport track 1 extends out of the multi-layer frame structure 7 to form a cantilevered section;

[0037] A trolley 2 for transporting the laminated panels, the trolley 2 being slidably connected to the transport track 1;

[0039] A lifting device for lifting the composite plate on the trolley 2 is connected to the upper layer of the layer to be constructed.

[0040] By setting up a transport track 1 and a cantilevered section extending out of the multi-layer frame structure 7, it is convenient to lift the composite panels outside the multi-layer frame structure 7 and use the trolley 2 to transport the composite panels into the multi-layer frame structure 7, thereby avoiding the problem of narrow lifting space inside the multi-layer frame structure 7.

[0042] Specifically, the support column 3 and the cantilever section are connected by bolts.

[0043] By providing the support column 3, a supporting force is provided for the cantilever section, thereby ensuring the stability of the cantilever section.

[0044] Specifically, the support column 3 is a telescopic rod.

[0045] By providing the telescopic rod, the length of the telescopic rod can be adaptively adjusted as the height of the installation layer of the transport track 1 changes, thereby always satisfying the supporting effect and improving practicality.

[0047] By setting the steel cable 6 to pull the cantilever section, when the trolley 2 is located in the cantilever section, the cantilever section tends to move downward due to gravity. The steel cable 6 provides an upward pulling force, which relieves the bearing capacity of the support column 3 and further improves the stability of the cantilever section.
