[0002] In the hydraulic integral lifting project, reasonable and safe lifting points need to be set on the structure. The common solution is to weld lifting lugs on the steel structure. However, in the integral lifting construction of the cable net of the aluminum cable-bearing structure, lifting lugs cannot be welded on the aluminum alloy beam, and the stiffness of the aluminum alloy material is relatively low. If the form of setting through bolts by drilling holes in the aluminum alloy beam is adopted to set the lifting points, on the one hand, it is easy to cause local buckling of the aluminum alloy beam, and on the other hand, it will reduce the bearing capacity of the aluminum alloy beam.

[0003] At present, there is no equipment for the integral lifting of the aluminum cable-bearing structure in China. The common upper structures of the integral lifting of the cable net are all steel structures, and the integral lifting points of the cable net can be arranged on the upper steel structure by welding. There is no solution to the problem that welding is impossible and bolt connection will cause the reduction of the strength of the original structure when the upper structure is an aluminum alloy roof. Therefore, a fixing device suitable for the integral lifting of the cable net of the aluminum cable-bearing structure is proposed. Content of the Utility Model

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 shown, the present invention provides a technical solution for a fixing device applicable to the overall lifting of an aluminum cable structure cable net, including an aluminum alloy double beam 1. The aluminum alloy double beam 1 is in an I shape. A load-bearing cross beam 3 is provided at the connection of the aluminum alloy double beams 1. Adapter pieces 2 are provided on both the upper and lower surfaces of the aluminum alloy double beam 1. A stabilizer 4 is provided below the load-bearing cross beam 3. A lifting device 7 is provided above the load-bearing cross beam 3. A steel strand 6 is connected to the lifting device 7. A clamping piece 5 is provided between the load-bearing cross beam 3 and the stabilizer 4. The adapter pieces 2, the load-bearing cross beam 3, the stabilizer 4 and the clamping piece 5 form a fixing device. The lifting device 7 and the steel strand 6 are fixedly connected by bolts. During the process of the lifting device 7 pulling the steel strand 6 to climb upward, the load is transmitted to the load-bearing cross beam 3, and then transmitted to the aluminum alloy double beam 1 by the adapter piece 2. And the load-bearing cross beam 3 and the stabilizer 4 are horizontally placed and parallel to each other, which can ensure the stability during the lifting process.

[0023] As Figure 2 shown, adapter pieces 2 are provided on both the upper and lower surfaces of the aluminum alloy double beam 1. The adapter pieces 2 are fixedly connected to the load-bearing cross beam 3 by spot welding, and the adapter pieces 2 are fixedly connected to the stabilizer 4 by spot welding. The load-bearing cross beam 3 and the stabilizer 4 are respectively clamped on the aluminum alloy double beam 1 by the clamping piece 5. The upper part of the load-bearing cross beam 3 abuts against the lifting device 7. The lifting device 7 and the steel strand 6 are fixedly connected together by bolts.

[0024] Specifically, a hard rubber sheet 21 is pasted on the side of the adapter piece 2 close to the aluminum alloy double beam 1. The side of the adapter piece 2 close to the aluminum alloy double beam 1 is parallel to the aluminum alloy beam. The other side of the adapter piece 2 is parallel to the load-bearing cross beam 3 or the stabilizer 4, providing a reliable horizontal plane for the lifting device 7 and keeping the lifting force vertically upward. The use of the hard rubber sheet 21 improves the original friction coefficient between aluminum and steel.

[0025] As Figure 3 and Figure 4As shown in the figure, the load-bearing crossbeam 3 and the stabilizer 4 are parallel to each other in the horizontal direction. There are two mutually parallel first channel steels 32 on the load-bearing crossbeam 3. First end plates 31 are welded to both ends of the first channel steel 32. There are two mutually parallel second channel steels 42 on the stabilizer 4. Second end plates 41 are welded to both ends of the second channel steel 42.

[0026] Specifically, when the load-bearing crossbeam 3 and the stabilizer 4 are horizontally placed, they are parallel to each other, which can ensure the stability during the lifting process. Both the first channel steel 32 and the second channel steel 42 are stuck on the clamping plate 53, so that the two channel steels will not be misaligned.

[0027] As Figure 5 shown in the figure, a clamping member 5 is provided between the load-bearing crossbeam 3 and the stabilizer 4. The clamping member 5 includes a precision rolled nut 51, a threaded steel bar 52 and a clamping plate 53. The clamping plates 53 are respectively connected to the load-bearing crossbeam 3 and the stabilizer 4. A threaded steel bar 52 is provided between the clamping plates 53. Precision rolled nuts 51 are provided at the edges of both ends of the threaded steel bar 52.

[0028] Specifically, the clamping member 5 clamps and fixes the load-bearing crossbeam 3 and the stabilizer 4 through the threaded steel bar 52, the clamping plate 53 and the precision rolled nut 51. By clamping the aluminum alloy double beam 1 through the clamping member 5, a reliable reaction force point is provided for the lifting device 7, solving the problem that ear plates cannot be welded on the aluminum alloy double beam 1 and bolt connection will cause the reduction of the original structure strength, ensuring the reliability of important lifting points, with less on-site welding operations, convenient for fabrication, transportation and installation, and improving the construction efficiency of the overall cable net lifting project.

[0029] Working principle: During use, the aluminum alloy double beam 1 is placed between the load-bearing crossbeam 3 and the stabilizer 4. After the aluminum alloy double beam 1 is placed between the load-bearing crossbeam 3 and the stabilizer 4, the clamping plate 53 can be clamped on the load-bearing crossbeam 3 and the stabilizer 4. Then the threaded steel bar 52 can be connected to the clamping plate 53. After the threaded steel bar 52 is connected to the clamping plate 53, the precision rolled nut 51 can be tightened. After the precision rolled nut 51 is tightened, the aluminum alloy double beam 1 can be fixed between the load-bearing crossbeam 3 and the stabilizer 4. Then the steel strand 6 can be pulled to climb upward. During the upward climbing process of the steel strand 6, the load is transmitted to the load-bearing crossbeam 3, and is transmitted to the aluminum alloy double beam 1 by the adapter 2. Moreover, the load-bearing crossbeam 3 and the stabilizer 4 are horizontally placed and parallel to each other, which can ensure the stability during the lifting process. And during the lifting process, the lifting device 7 provides a reliable horizontal plane, keeping the lifting force vertically upward, and the use of the hard rubber sheet 21 improves the original friction coefficient between aluminum and steel.
