Description

A tool for lifting and installing exterior wall panels Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a tool for lifting and installing exterior wall panels. Background Technology

[0002] With the booming development of prefabricated buildings in China, precast prestressed technology has gradually taken a dominant position in the construction market due to its many advantages, such as short construction period, low cost, energy saving and environmental protection, high strength, good crack resistance, and large load-bearing capacity. It is highly compatible with the development requirements of building industrialization and standardization. In traditional construction methods, masonry walls and ordinary cast-in-place concrete walls have the problem of long construction period, and various formworks are required during construction, which not only increases costs but also has a certain impact on the environment. The emergence of precast wall panels has perfectly solved the problems of construction period, quality, and environmental protection, and therefore has been increasingly widely used.

[0003] In the application of precast wall panels, the hoisting process is crucial. However, there is a lack of efficient and reliable hoisting tools on the market specifically designed for the molding and hoisting process of large exterior wall panels. Existing hoisting tools often cannot meet the hoisting needs of all large exterior wall panels, and their applicability is quite limited. For prefabricated civil buildings and prefabricated industrial buildings, existing hoisting tools are not conducive to accelerating the application and promotion of steel structure and precast concrete building systems.

[0004] During the hoisting process, the flatness of the wall surface is one of the important indicators for measuring the quality of the building. Existing hoisting tools are difficult to guarantee that the flatness of the wall surface fully meets the design requirements. At the same time, there are also certain safety hazards in the hoisting process. In addition, the existing hoisting tools need to be further improved in terms of technological advancement, safety applicability, and economic rationality.

[0005] Therefore, developing a lifting tool applicable to the molding and hoisting process of all large exterior wall panels has become an urgent problem to be solved in the field of prefabricated buildings. Summary of the Invention

[0006] To address the aforementioned issues, this utility model provides an external wall panel lifting tool that can meet the lifting requirements of different large external wall panels, improves the applicability of the lifting tool in prefabricated civil and industrial buildings, and helps to accelerate the application and promotion of steel structure and precast concrete building systems.

[0007] The technical solution of this utility model is as follows:

[0008] An external wall panel formwork hoisting tool includes a truss beam and a hoisting beam. The truss beam includes an upper main beam and two lower main beams, with the two lower main beams arranged in parallel. The upper main beam is positioned above the lower main beams and at the center between the two lower main beams. A truss beam lifting lug is provided at the top of the upper main beam, and fixed seats are respectively provided on the outer sides of the two lower main beams. The hoisting beam includes a hoisting main beam, which is fixedly connected to the fixed seats. Two or more hoisting beam lifting lugs are provided at the bottom of the hoisting main beam.

[0009] The two lower main beams are connected by several second straight connecting beams.

[0010] Two second oblique connecting beams are also provided between two adjacent second straight connecting beams. One end of each second oblique connecting beam is connected to one of the two lower main beams, and the other end of each second oblique connecting beam is connected to the other lower main beam. The two second oblique connecting beams and the lower main beams form a stable triangular structure.

[0011] The upper main beam and the lower main beam are connected by several first straight connecting beams.

[0012] Two first oblique connecting beams are also provided between two adjacent first straight connecting beams. One end of the two first oblique connecting beams is connected to the upper main beam, and the other end of the two first oblique connecting beams is connected to the lower main beam. The two first oblique connecting beams and the lower main beam form a stable triangular structure.

[0013] Two truss beam lugs are provided at the top of the main beam, and the two truss beam lugs are symmetrically distributed at the center of the main beam above the main beam.

[0014] Several fixed seats are evenly distributed on the lower main beam.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses an external wall panel formwork lifting tool. This external wall panel formwork lifting tool addresses the current market lack of efficient and reliable lifting tools specifically designed for the formwork lifting process of large external wall panels, and the limited applicability of existing lifting tools. Through a specific structural design, it can meet the lifting needs of different large external wall panels, improve the applicability of lifting tools in prefabricated civil buildings and prefabricated industrial buildings, and help accelerate the application and promotion of steel structure and precast concrete building systems.

[0017] 2. This utility model discloses an external wall panel formwork lifting tool. The external wall panel formwork lifting tool has a reasonable design of the truss beam (including the upper main beam, the lower main beam and each connecting beam) and the lifting beam. Through the stable connection and reasonable layout of each component, the posture of the external wall panel can be better controlled when lifting the external wall panel, reducing the shaking and deformation of the external wall panel during the lifting process, thereby ensuring that the flatness of the wall surface fully meets the design requirements and improving the building quality.

[0018] 3. This utility model discloses an external wall panel formwork lifting tool. This external wall panel formwork lifting tool forms a stable structure by setting multiple connecting beams (such as a first straight connecting beam, a second straight connecting beam, a first oblique connecting beam, and a second oblique connecting beam). The oblique connecting beams form a stable triangular structure with the main beam, which enhances the strength and stability of the entire truss beam. At the same time, the lifting lugs of the truss beam and the lifting beam are reasonably set to ensure uniform and stable force during lifting, effectively reducing the safety risks in the lifting process and improving the safety of the lifting operation.

Detailed Implementation

[0028] As shown in Figure 1, the external wall panel lifting and hoisting tool mainly consists of two welded steel structures: truss beam 100 and hoisting beam 200. Truss beam 100 serves as the main frame of the entire lifting tool and bears the main load-bearing load. Hoisting beam 200 is used to connect with the external wall panel to realize the lifting and transportation of the external wall panel.

[0029] As shown in Figures 2 and 3, the truss beam 100 mainly consists of an upper main beam 110 and a lower main beam 120.

[0030] The upper main beam 110 uses a 200×8 square tube with a length of 15600 (all dimensions mentioned above are in mm, and all dimensions mentioned below are in mm, and will not be described again). It can provide sufficient strength and rigidity to withstand the tension and pressure during the hoisting process, ensuring that no deformation occurs when hoisting large wall panels, and guaranteeing the safety and stability of the hoisting.

[0031] The lower main beam 120 uses a 150×6 square tube with a length of 15600. The two lower main beams 120 are set in parallel, and the upper main beam 110 is set above the lower main beams 120 and located at the center between the two lower main beams 120. The truss beam 100 is subjected to uniform stress, which enhances the stability of the structure.

[0032] Several first straight connecting beams 130 connect the upper main beam 110 and the lower main beam 120. Two first oblique connecting beams 140 are arranged between two adjacent first straight connecting beams 130, with one end connected to the upper main beam 110 and the other end connected to the lower main beam 120. The two first oblique connecting beams 140 and the lower main beam 120 form a stable triangular structure. This triangular structure has extremely high stability, effectively enhancing the deformation resistance of the truss beam 100 and better withstanding various external forces during hoisting.

[0033] Several second straight connecting beams 150 connect two lower main beams 120. Two second oblique connecting beams 160 are arranged between two adjacent second straight connecting beams 150, with one end connected to either of the two lower main beams 120 and the other end connected to the other lower main beam 120. The two oblique connecting beams 160 and the lower main beams 120 form a stable triangular structure. This also enhances the connection strength and stability between the two lower main beams 120, ensuring that the two lower main beams 120 will not experience relative displacement or deformation during hoisting.

[0034] The truss beam lifting lugs 170 are made of 25mm thick steel plates and are set on the top of the upper main beam 110. There are two lugs, symmetrically distributed at the center of the upper main beam 110. The lugs are used to connect the wire ropes of the lifting equipment (such as cranes). The symmetrical distribution design ensures that the force is evenly distributed during the lifting process, avoiding tilting or damage to the upper main beam 110 due to uneven force distribution. At the same time, the 25mm thick steel plate ensures that the lugs have sufficient strength to withstand the lifting weight. In addition, the truss beam lifting lugs 170 are also equipped with several 16mm thick reinforcing ribs, which further enhance the strength and stability of the lugs.

[0035] The fixed seat 180 is made of 12mm thick steel plate, and several are evenly distributed on the lower main beam 120. The fixed seat 180 is used to connect the lifting beam 200. The even distribution makes the connection of the lifting beam 200 on the truss beam 100 more stable, and can evenly transmit the lifting force to ensure the stability of the lifting process. At the same time, the fixed seat 180 is equipped with several 8mm thick reinforcing ribs, which improves the load-bearing capacity of the fixed seat 180.

[0036] As shown in Figure 4, the hoisting beam 200 includes a main hoisting beam 210, which is made of 250×250×8×12 H-beams with a length of 4300 mm. H-beams have high strength and good bending resistance, capable of bearing the weight of the exterior wall panels, and are not prone to bending deformation during hoisting, ensuring safe and reliable hoisting. The main hoisting beam 210 is fixedly connected to the fixed seat 180 by bolts or other means, and is connected to the truss beam 100 through the fixed seat 180.

[0037] The lifting lugs 220 of the lifting beam are made of 16mm thick steel plates and are set at the bottom of the main lifting beam 210, with two or more of them. The lifting lugs 220 are used to connect the lifting rings on the outer wall panels and connect the outer wall panels to the lifting beam 200 by steel wire ropes. The setting of multiple lifting lugs 220 can be flexibly adjusted according to actual lifting needs to achieve 6-point lifting of large wall panels, so that the wall panels are evenly stressed during the lifting process and reduce the risk of damage to the wall panels.

[0038] The working process of this exterior wall panel lifting and hoisting tool is as follows:

[0039] Preparation: Based on the size and weight of the exterior wall panel, structural mechanics calculations are performed to ensure that the structural design of the lifting tool for the exterior wall panel lifting formwork has a lifting capacity of 20 tons, which meets the requirements. The lifting tool is assembled, and all connections are checked to ensure that the connection between the truss beam 100 and the lifting beam 200 is stable and that all lifting lugs and fixing seats are undamaged.

[0040] Connecting the exterior wall panels: The lifting lugs 220 at the bottom of the lifting beam 200 are connected to the bolts and lifting rings inserted into the sleeves on the exterior wall panels using steel wire ropes. Since the lifting device is designed to lift large wall panels in a 6-point manner, the connection points of the steel wire ropes need to be reasonably distributed according to the actual situation to ensure that the exterior wall panels are subjected to uniform force during the lifting process.

[0041] Lifting process: Using cranes and other lifting equipment, the lifting lugs 170 on the top of the truss beam 100 are connected by steel wire ropes, and the lifting equipment is slowly lifted so that the outer wall panel is gradually lifted off the ground. During the lifting process, the condition of the lifting tools and the outer wall panel is closely observed to ensure that there is no abnormal shaking or deformation. Due to the stable triangular structure formed by the connecting beams of the truss beam 100 and the reasonable size and layout of the parts, it can effectively withstand various external forces during the lifting process, ensuring the safety and stability of the lifting process.

[0042] Handling and installation: After hoisting the exterior wall panels to the designated location, the hoisting equipment is slowly lowered to ensure that the exterior wall panels are accurately positioned. During the handling and installation process, the stable structure and reasonable design of the hoisting tools can ensure the positional accuracy of the exterior wall panels, reduce installation errors, and improve construction efficiency.

[0043] Disassembly: After the exterior wall panels are installed, loosen the connection between the wire rope and the lifting ring, and remove the lifting tools from the exterior wall panels to prepare for the next lifting operation.
