Description

Technical Field

[0001] The utility model belongs to the technical field of tower crane wall attachments, and particularly relates to a high - adaptability force - transfer device for tower crane attachments at wall hole positions. Background Technique

[0002] In existing construction projects, tower cranes, as indispensable vertical and horizontal transportation equipment, the design and installation of their attachment and force - transfer systems directly affect construction safety and efficiency. However, with the rapid development of prefabricated building technology, especially the wide application of fully prefabricated shear wall and precast column structural systems, traditional tower crane attachment methods face severe challenges.

[0003] Specifically, in precast shear wall or precast column structures with fully prefabricated vertical members, since grouting sleeves are used to connect vertical members, the space is limited at the joint positions of upper and lower members (i.e., at the floor height), making it impossible to directly embed and install tower crane wall attachments. This space limitation not only increases the difficulty of tower crane attachment but also affects the verticality and lateral stability of the tower crane, posing potential safety hazards to construction. In addition, even by adjusting the attachment height of the tower crane to avoid these restricted areas, it is often limited by the length, angle, and mechanical properties of the tower crane attachment device itself. Especially when encountering complex structures such as large - area bay windows, the selection of tower crane attachment points becomes particularly difficult, further exacerbating the construction difficulty.

[0004] In view of the above - mentioned technical problems, the utility model proposes a high - adaptability force - transfer device for tower crane attachments at wall hole positions. Content of the Utility Model
