[0030] As Figure 2 shown, the steel truss 30 comprises an upper flange steel beam 31, a lower flange steel beam 32, a straight web steel beam 33 and an inclined web steel beam 34, the upper flange steel beam 31 is arranged above the lower flange steel beam 32, the straight web steel beam 33 is connected between the upper flange steel beam 31 and the lower flange steel beam 32, and the inclined web steel beam 34 is connected between the upper flange steel beam 31 and the lower flange steel beam 32. By arranging the upper flange steel beam 31 and the lower flange steel beam 32 and connecting the straight web steel beam 33 and the inclined web steel beam 34 between the upper flange steel beam 31 and the lower flange steel beam 32, the stress system is simple, has strong bending resistance, large bearing capacity and can bear the great vertical load brought by the luffing-jib tower crane, thereby improving the safety and reliability. Preferably, the first end of the inclined web steel beam 34 is connected at the position where the straight web steel beam 33 and the upper flange steel beam 31 are connected, and the second end of the inclined web steel beam 34 is connected at the position where the adjacent straight web steel beam 33 and the lower flange steel beam 32 are connected, thereby improving the load performance.

[0031] In the embodiment, as Figure 3 and Figure 4As shown, the concrete coupling beam 20 includes a first coupling beam 21, a second coupling beam 22, a third coupling beam 23 and a fourth coupling beam 24, the first coupling beam 21 and the second coupling beam 22 are oppositely arranged, the first end of the upper flange steel beam 31 is arranged on the first coupling beam 21, and the second end of the upper flange steel beam 31 is arranged on the second coupling beam 22.

Through the steel truss 30 and the concrete coupling beam 20, the load can be uniformly distributed on the four concrete coupling beams 20, thereby improving the load capacity.

[0032] Further, the tower crane support structure further includes a first embedded part 51, a first connecting plate 61 and a second connecting plate 62, the first embedded part 51 is arranged on all the concrete coupling beams 20 respectively; the first connecting plate 61 is arranged on the first embedded part 51 on the first coupling beam 21, and the first end of the upper flange steel beam 31 is connected to the first connecting plate 61; the second connecting plate 62 is arranged on the first embedded part 51 on the third coupling beam 23, and the first end of the lower flange steel beam 32 is connected to the second connecting plate 62. The first connecting plate 61 is welded to the first embedded part 51 of the first coupling beam 21, and the first end of the upper flange steel beam 31 is welded to the first connecting plate 61, so as to realize the connection and fixation of the upper flange steel beam 31 and the first coupling beam 21. The second connecting plate 62 is welded to the first embedded part 51 of the third coupling beam 23, and the first end of the lower flange steel beam 32 is welded to the second connecting plate 62, so as to realize the connection and fixation of the upper flange steel beam 31 and the first coupling beam 21. Preferably, the first connecting plate 61 and the second connecting plate 62 are both steel plates,

[0033] Further, the tower crane support structure further comprises a first limiting frame 63 and a second limiting frame 64. The first limiting frame 63 is arranged on the first embedded part 51 of the second cross beam 22, and the second end of the upper flange steel beam 31 is in limiting cooperation with the first limiting frame 63. The first limiting frame 63 is used to limit the vertical movement of the upper flange steel beam 31. The second limiting frame 64 is arranged on the first embedded part 51 of the fourth cross beam 24, and the second end of the lower flange steel beam 32 is in limiting cooperation with the second limiting frame 64. The second limiting frame 64 is used to limit the vertical movement of the lower flange steel beam 32. A steel plate is welded on the first embedded part 51 of the second cross beam 22. A polytetrafluoroethylene plate is arranged on the steel plate. The second end of the upper flange steel beam 31 is slidingly arranged on the polytetrafluoroethylene plate. The first limiting frame 63 is L-shaped. Two first limiting frames 63 are oppositely arranged and simultaneously welded on the first embedded part 51 of the second cross beam 22. The two first limiting frames 63 and the first embedded part 51 form a clamping groove in the shape of an inverted T. The second end of the upper flange steel beam 31 is movably arranged in the clamping groove. The friction coefficient between the steel plates is reduced by the characteristics of the polytetrafluoroethylene plate. The first limiting frame 63 is used to limit the vertical movement of the second end of the upper flange steel beam 31. Since the upper flange steel beam 31 can move relative to the second cross beam 22 in the length direction of the upper flange steel beam 31, the lateral force transmitted by the steel truss 30 to the concrete cross beam 20 can be greatly eliminated.

[0034] Similarly, a steel plate is welded on the first embedded part 51 of the fourth cross beam 24. A polytetrafluoroethylene plate is arranged on the steel plate. The second end of the lower flange steel beam 32 is slidingly arranged on the polytetrafluoroethylene plate. The number and installation mode of the second limiting frame 64 are the same as those of the first limiting frame 63. The second end of the lower flange steel beam 32 is movably arranged in the clamping groove formed by the two second limiting frames 64 and the corresponding first embedded part 51. The lateral force transmitted by the steel truss 30 to the concrete cross beam 20 can be greatly eliminated.

[0035] Further, the tower crane support structure further comprises a pull rod 70. The pull rod 70 is connected to the steel truss 30. The steel truss 30 is connected to the shear wall 10 through the pull rod 70. It should be noted that the pull rod 70 is welded on the outer side of the steel truss 30. The pull rod 70 is connected to the shear wall 10 to balance the horizontal force of the steel truss 30. The steel material is Q355B. The connection is fully welded. The welding method is carbon dioxide gas shielded welding. In addition, in order to further improve the reliability, the pull rod 70 can also be connected to the concrete cross beam 20. It should be noted that the second embedded part 52 is arranged in the shear wall 10. The pull rod 70 is connected to the second embedded part 52.

[0036] It should also be noted that, as shown in Figure 5 the first embedded part 51 and the second embedded part 52 are both small-section I-shaped steel used as anchor rods. In the case of meeting the truss force requirement, the requirements of the concrete beam steel bar are considered. The whole is embedded, and the construction is convenient.

[0037] According to another aspect of the present application, a construction method for the tower crane supporting structure is also disclosed, comprising the following steps: S10: pouring the shear wall 10 and the concrete coupling beam 20 of the core tube, and embedding the embedded part in the shear wall 10 and the concrete coupling beam 20 before pouring; S20: installing two steel trusses 30 on the poured concrete coupling beam 20, and fixing the trusses with the embedded part; S30: fixing the two steel trusses 30 through the secondary beam 40; S40: connecting the upper steel truss 30 with the embedded part through the connecting rod.

[0038] It should be noted that, for different site conditions, the shear steel plate needs to be additionally arranged in the core tube concrete beam, and the shear wall 10 in the core tube needs to be additionally reinforced to improve the strength, ensure the safety and reliability. The main structure concrete is reinforced before the steel truss 30 is installed to ensure that the strength reaches 100%, and the counterforce design value acting on the main structure during the use of the tower crane should not be greater than the counterforce limit value of the tower crane foundation support; after the construction is completed, the welding part of the tower crane foundation is detected, and only after the detection is qualified, the tower crane can be used, and the stress and strain of the concrete coupling beam 20 and the steel truss 30 in the core tube are detected during the use of the tower crane to ensure the safety.

[0039] From the above description, it can be seen that the above-mentioned embodiments of the present application are convenient to assemble and disassemble, can shorten the foundation construction period, the materials can be recycled, and the safety is relatively high, so that the utilization rate of the tower crane can be improved.
