AI Technical Summary
The installation of tower cranes presents many challenges in setting up attachment points, especially when there are climbing frames or two-force members on the exterior facade of the building with limited installation angles. This makes it difficult to set up attachment points, which may lead to uneven stress on the floor slab and affect the structural safety and stability.
A concrete reinforcement layer is set at the tower crane attachment point, and the structural strength is enhanced by the fixed connection of the steel mesh with the reinforcement in the beam and the reinforcement in the floor slab. The structure is formed by using main bars, distribution bars, stirrups, reinforcing bars and bent hooks.
It significantly improves the structural strength and stability at the tower crane attachment point, prevents the floor slab from being damaged by additional stress, and enhances the overall structural safety and stability.

Abstract
Description
Technical Field
[0001] This application relates to the field of structural reinforcement technology, and in particular to a reinforcement structure for the main body of a tower crane attachment point. Background Technology
[0002] Currently, the placement of attachment points is crucial during tower crane installation. To ensure the stability and safety of the tower crane, a three-point support method is typically used, where each set of three two-force members attaches the tower crane to the beams of the main building's exterior facade. However, in practice, the placement of attachment points faces numerous challenges due to the presence of climbing scaffolding on the building facade or limitations imposed by the installation angle of the two-force members.
[0003] To meet the requirements for tower crane attachment points, it is sometimes necessary to extend one end of the two-force member into the floor slab and fix it to the floor surface. While this solves the attachment point problem, it also places additional stress on the floor slab, potentially leading to damage. Such damage not only affects the normal use of the floor slab but may also threaten the safety of the overall structure. Utility Model Content
[0004] In order to improve the structural strength of the floor slab stress points, this application provides a reinforcement structure for the main structure at the tower crane attachment point.

[0007] By adopting the above technical solution, and by setting a concrete reinforcement layer at the attachment point, and coordinating the connection between the steel mesh and the main structure, the structural strength at the tower crane attachment point is effectively enhanced, preventing the floor slab from being damaged due to additional stress.
[0008] Optionally, the steel mesh includes vertically connected main bars and distribution bars. One end of the main bars is connected to the reinforcement in the beam, and the other end is connected to the inner reinforcement of the floor slab.

[0013] By adopting the above technical solution, the structural design of the hook section makes the steel mesh more stable when subjected to external forces.
[0014] Optionally, the steel mesh includes a number of vertically connected stirrups and a number of primary reinforcement bars; the stirrups extend vertically and are connected to the reinforcement bars in the beam; the primary reinforcement bars are surrounded by the stirrups and extend horizontally along the direction of the beam.
[0015] By adopting the above technical solution, a steel mesh structure adapted to the stress characteristics of beams and floor slabs is provided, which improves the overall strength and stability at the attachment points.
[0016] Optionally, the steel mesh further includes reinforcing bars, each reinforcing bar comprising an inclined section and horizontal sections connected at both ends of the inclined section. One of the horizontal sections is fixedly connected to the first reinforcement bar at the top of the stirrup, and the other horizontal section is fixedly connected to the inner reinforcement bar of the floor slab.
[0017] By adopting the above technical solution, the stress performance of the steel mesh is enhanced.
[0018] Optionally, a plurality of second reinforcing bars parallel to the first reinforcing bars are fixedly connected within the inclined section; the plurality of second reinforcing bars are arranged along the extension direction of the inclined section, and the steel mesh further includes tie bars connecting the first reinforcing bars and the second reinforcing bars.
[0019] By adopting the above technical solution, a second set of reinforcement bars and tie bars are set in the inclined section, which further enhances the stability of the steel mesh.
[0020] Optionally, the end of the horizontal segment is fixed with a bent hook extending toward the inclined segment.
[0021] By adopting the above technical solution, the connection strength between the horizontal section and the first reinforcement and the inner reinforcement of the floor slab is enhanced, thereby improving the stability and safety of the overall structure.
[0022] Optionally, the horizontal section connected to the floor slab includes an inner extension rod extending toward the direction of the stirrups and an outer extension rod extending away from the stirrups, the ends of which are fixed with bent hooks extending toward the inclined section.
[0023] By adopting the above technical solution, the composition of the horizontal section is refined, making it more stable when subjected to external forces, thereby improving the structural strength at the attachment point.

[0035] The present application will be further described in detail below with reference to the accompanying drawings.
[0036] This application discloses a reinforcement structure for the main structure at the attachment point of a tower crane.
[0037] Example 1
[0038] Reference Figure 1 , 2The structural reinforcement at the tower crane attachment point includes a concrete reinforcement layer 1, which is formed at the attachment point by casting in place with the floor slab 5 and beam 4. This concrete reinforcement layer 1 includes a steel mesh 2, which is fixedly connected to the reinforcement 41 in the beam 4 and the inner slab reinforcement 51 of the floor slab 5. The connection between the steel mesh 2 and the reinforcement 41 and inner slab reinforcement 51 can be achieved using tie wire (the kind used for binding steel bars in construction) or by welding. After the steel mesh 2 is connected to the reinforcement 41 in the beam 4 and the inner slab reinforcement 51 in the floor slab 5, concrete pouring is performed, which improves the structural strength of the concrete reinforcement layer 1.
[0039] Reference Figure 2 , 3 The steel mesh 2 includes vertically connected main bars 21 and distribution bars 22, with several main bars 21 and distribution bars 22 distributed in each. One end of the main bar 21 is connected to the reinforcement 41 in the beam 4, and the other end is connected to the inner slab reinforcement 51 of the floor slab 5. Similarly, the distribution bars 22 are connected to the inner slab reinforcement 51 of the floor slab 5, forming a stable load-bearing system.
[0040] Reference Figure 2 , 4 To further enhance the anchorage force between the reinforcing mesh 2 and the concrete, the ends of the main reinforcement 21 connected to the inner reinforcement 51 of the floor slab 5 and the two ends of the distribution reinforcement 22 are all fixedly connected with outwardly extending hook portions 23. The hook portions 23 at both ends of the distribution reinforcement 22 extend outward in a direction away from each other. The hook portion 23 of the main reinforcement 21 includes an outer hook section 231 extending outward along the parallel main reinforcement 21. The hook portion 23 can also be effectively fixedly connected to the inner reinforcement 51 of the floor slab 5 by means of wire binding or welding.
[0041] Example 2
[0042] The difference between Example 2 and Example 1 is that Example 2 uses a different method of constructing the steel mesh 2, as described above. Figure 5 , 6 The steel mesh 2 includes several vertically connected stirrups 31 and several primary reinforcement bars 32. The stirrups 31 extend vertically and connect with the reinforcement bars 41 in the beam 4. The primary reinforcement bars 32 are surrounded by the stirrups 31 and extend horizontally along the direction of the beam 4.
[0043] To further optimize the load-bearing structure, the steel mesh 2 includes reinforcing bars 33, which are inclined and supported at the rear end of the stirrups 31, forming an inclined support. The reinforcing bar 33 includes an inclined section 331 and horizontal sections 332 connected to both ends of the inclined section 331. The inclined section 331 and the horizontal section 332 are integrally formed. One horizontal section 332 of the reinforcing bar 33 is fixedly connected to the first reinforcing bar 32 at the top of the stirrup 31, and the other horizontal section 332 is fixedly connected to the inner slab reinforcing bar 51 of the floor slab 5.
[0044] Several secondary reinforcing bars 34, parallel to the primary reinforcing bars 32, are also fixedly connected within the inclined section 331. These secondary reinforcing bars 34 are arranged at equal intervals along the inclined direction of the inclined section 331. Tie bars 35 are fixed between the primary reinforcing bars 32 and secondary reinforcing bars 34 at the same horizontal height. The tie bars 35 connect the primary reinforcing bars 32 and secondary reinforcing bars 34, forming a more stable load-bearing system. Both ends of the tie bars 35 are integrally formed with elbows 351, which hook onto the primary reinforcing bars 32 and secondary reinforcing bars 34 respectively. The elbows 351 increase the structural strength of the connection between the tie bars 35 and the primary and secondary reinforcing bars 32 and 34. Simultaneously, the reinforcing bars 33 have bent hooks 333 extending towards the inclined section 331 at the end of the horizontal section 332, further increasing the anchorage force between the reinforcing bars and the concrete.
[0045] Example 3
[0046] Reference Figure 7 The difference between Embodiment 3 and Embodiment 1 is that the hook portion 23 of the main reinforcement 21 also includes an inner hook section 232 extending inward along the parallel main reinforcement 21. The combination of the inner hook section 232 and the outer hook section 231 can effectively improve the anchorage effect of the main reinforcement 21.
[0047] Example 4
[0048] Reference Figure 8 The difference between Embodiment 4 and Embodiment 2 is that the horizontal segment 332 connected to the floor slab 5 includes an inner extension rod 3321 extending toward the direction close to the stirrup 31 and an outer extension rod 3322 extending away from the stirrup 31. The ends of the inner extension rod 3321 and the outer extension rod 3322 are both fixed with bent hooks 333 extending toward the inclined segment 331, which optimizes the force distribution and anchoring effect of the horizontal segment 332.
[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
