AI Technical Summary
The existing old structural side beams do not meet the bearing capacity required for tower cranes to attach walls, resulting in the inability to connect the tower cranes to attach walls, which poses safety hazards.
A connecting member for the tower crane with a wall is designed, including ear plates and two eight-shaped supporting steels. The ear plates are installed on the inside of the wall-attached structure beam, and the support steel is arranged between the inner side of the wall-attached structure beam and the secondary beam or shear wall to reinforce the support wall-attached point.
By reinforcing the wall attachment point, the force carried by the wall attachment point on the wall attachment structure beam is transmitted inward to the secondary beam or shear wall, so as to achieve reliable plane direction constraints of the wall attachment structure beam at the wall attachment point, avoiding verification of the bearing capacity of the existing old structure side beam.

[0025] Please refer to Figure 1 , which is a schematic plan view when the tower crane attachment wall is connected to the attachment wall structural beam in an embodiment of the present utility model. As Figure 1 shown, the connecting members of the tower crane attachment wall include: the ear plate 1 is installed on the inner side of the attachment point on the attachment wall structural beam, and two support steel profiles 2 are arranged in a spread shape between the inner side of the attachment wall structural beam and the secondary beam or shear wall in the bay on the inner side of the attachment wall structural beam to reinforce and support the attachment point.
[0026] When installing the tower crane, the connecting components of the present utility model are used for the connection and installation of the tower crane attachment wall. By adding two support steel beams 2 between the inner side of the attachment wall structural beam and the secondary beam or shear wall located in the inner bay of the attachment wall structural beam, while strengthening the attachment wall point, the force borne by the attachment wall point on the attachment wall structural beam is transmitted inward to the secondary beam or shear wall, so that the attachment wall structural beam has a reliable out-of-plane direction constraint at the attachment wall point, to ensure the force transmission stability of the tower crane attachment wall members and the safety of the attachment wall structural beam. It not only solves the problem that the tower crane attachment wall cannot be connected when the bearing capacity of the existing old structure is insufficient, but also ensures the safe construction of the tower crane attachment wall, guarantees the construction efficiency of the construction, and provides ideas for applying this technical principle to solve some problems in other similar projects or similar construction processes.
[0027] Please refer to Figure 2 and Figure 3 , the connecting component further includes: four fixing components 3, and every two fixing components 3 are arranged on both sides of a support steel beam 2 to fix the end of the support steel away from the attachment wall structural beam to the secondary beam or shear wall, specifically corresponding to Figure 1 the connection point ① between the support steel beam 2 and the secondary beam or shear wall in Figure 2 and Figure 3 are sectional views of ① at different angles; wherein, each fixing component 3 includes: a wall-piercing bolt 31, a nut 32 and a pressing plate 33 that are matched with the wall-piercing bolt 31, and the wall-piercing bolt 31 is preferably a Φ22 high-strength bolt for the connection point between the support steel beam 2 and the secondary beam or shear wall.
[0028] Preferably, the support steel beam 2 is an I-beam. In this embodiment, the support steel beam 2 is preferably a 20# I-beam.
[0029] To better understand the connecting component of the tower crane attachment wall of the present utility model, the following will be elaborated in detail with specific examples as follows: Figures 1 to 3 Specifically as follows:
[0030] Taking a project with a building height of 96.3m as an example, according to relevant requirements, the tower crane must be attached to the wall twice, and the relative elevation of the attachment wall is 39.9m and 67.8mm, corresponding to the 13th and 22nd structural floors. At the attachment wall points, secondary beams and shear walls are reserved in the inner bay of the attachment wall structural beam of each attachment wall structure layer. During the structure demolition period, the secondary beams, shear walls and floor slabs in the inner bay of the attachment wall structural beam are all reserved. The secondary beam or shear wall is 1.65m away from the structural beam where the attachment wall point is located. When installing the tower crane, ear plates 1 are installed on the inner side of the attachment wall point, and are connected to the secondary beams and shear walls on the inner side of the attachment wall structural beam through the support steel beams 2 to strengthen the attachment wall point; among them, there are two support steel beams 2 in total, which are distributed in a figure-eight shape. The specific layout is shown in Figure 1Through the reinforcement of the floor slab and the supporting steel section 2, the attached wall structural beam at the attached wall point has reliable out-of-plane direction constraints. The force borne by the attached wall point on the attached wall structural beam is transmitted inward to the secondary beam or shear wall based on the supporting steel section 2. Therefore, it is not necessary to check the bearing capacity of the attached wall structural beam, and thus there is no problem that the existing old structural side beam does not meet the bearing capacity required for the tower crane attached wall.
[0031] The general situation of the tower cranes on the construction site of this project is shown in the following table:
[0032]
[0033] It can be understood that the above examples are only examples listed for better understanding of the technical solutions of the embodiments of the present application and do not serve as the sole limitation of this embodiment.
[0034] In summary, in the connecting member of the tower crane attached wall provided by the present utility model, the connecting member of the tower crane attached wall includes an ear plate and two supporting steel sections. The ear plate is installed inside the attached wall point on the attached wall structural beam, and the two supporting steel sections are arranged in a spread shape between the inside of the attached wall structural beam and the secondary beam or shear wall located in the bay inside the attached wall structural beam to reinforce and support the attached wall point. By adding two supporting steel sections between the inside of the attached wall structural beam and the secondary beam or shear wall located in the bay inside the attached wall structural beam, while reinforcing the attached wall point, the force borne by the attached wall point on the attached wall structural beam is transmitted inward to the secondary beam or shear wall, so that the attached wall structural beam has reliable out-of-plane direction constraints at the attached wall point. Therefore, it is not necessary to check the bearing capacity of the existing old structural side beam.
