Description

Technical field:

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a tower crane attached to a wall structure. Background technology:

[0002] Super high-rise buildings are generally steel-concrete hybrid structures. The greater the lifting weight, the larger the steel structure segment, and the better the construction progress, but the corresponding cost is also higher. Therefore, as the height of the building gradually increases, in order to meet the lifting capacity of the steel components, the tower crane also needs to be upgraded. When the height of the tower crane exceeds the independent height, in order to ensure that the slenderness ratio of the tower steel structure can stabilize the balance of the tower steel structure and prevent instability, it is necessary to set up a wall attachment device to increase the stability of the slenderness ratio of the tower crane.

[0003] When arranging and selecting the tower crane, due to the influence of factors such as the building's external structure and the positioning of the tower crane's foundation, the tower crane's wall attachment needs to be connected to the core tube wall. The wall attachment frame is directly connected to the core tube wall, which hinders the normal construction of the floor working surface and lies across the main structure, causing the rods of the wall attachment frame to be too long, resulting in a surge in construction costs, and it is difficult to remove the tower crane's wall attachment after the construction is completed. Utility model content:

[0004] The utility model aims to provide a tower crane attached to the wall structure, which uses steel beams as connection nodes to transmit the force of the tower crane attached to the wall to the core tube wall through attachment rods, greatly reducing the length of the tower crane attached to the wall and solving the problems mentioned in the background technology.

[0005] The utility model is implemented by the following technical solution:

[0006] A tower crane attachment structure includes several core tube steel columns and several outer frame steel columns. There is a core tube wall between the core tube steel columns, and a transverse outer frame steel beam is arranged between the outer frame steel columns. The transverse outer frame steel beam is arranged parallel to the core tube wall. It also includes a longitudinal outer frame steel beam. One end of the longitudinal outer frame steel beam is fixedly connected to the core tube steel column, and the other end is fixedly connected to the outer frame steel column or the transverse outer frame steel beam. The longitudinal outer frame steel beam is perpendicular to the transverse outer frame steel beam. It further includes a tower crane. A first support is fixed on the side of the transverse outer frame steel beam close to the tower crane, and a second support is fixed on the side of the transverse outer frame steel beam close to the core tube steel column. The first support and the second support are on both sides of the same position of the web of the transverse outer frame steel beam. A third support is fixed within the included angle between the core tube steel column and the longitudinal outer frame steel beam close to the tower crane. An attachment frame is arranged between the tower crane and the first support, and an attachment tie rod is arranged between the second support and the third support. Attachment plates are arranged at both ends of the attachment tie rod. On the premise that the force-bearing is not considered in the design of the outer frame steel structure, an attachment tie rod is arranged in the steel structure system, with the outer frame steel beam as the connection node. The attachment frame, transverse outer frame steel beam, longitudinal outer frame steel beam, attachment tie rod, core tube wall, etc. cooperate with each other to form multiple horizontal triangles. Utilizing the characteristic of the steel structure to conduct force in the horizontal direction, the supporting force of the tower crane is transmitted to the core tube wall through the attachment frame, outer frame steel beam, and attachment tie rod. After the construction is completed, the attachment frame can be removed. This structure not only realizes the stable function of the tower crane attachment but also does not hinder the normal construction of the floor working surface, and is convenient for disassembly and assembly.

[0007] Further, the first support includes two parallel connecting plates. A fixing block is arranged between the two connecting plates. Fixing plates are arranged at both ends of the outside of the connecting plates. The bottoms of the connecting plates, the bottom of the fixing block, and the bottoms of the fixing plates are all fixed on the web of the transverse outer frame steel beam. Two through holes are opened at both ends of the connecting plates, and the end of the attachment frame is fixed between the two connecting plates through a pin shaft structure.

[0008] Further, the attachment plate close to the transverse outer frame steel beam is fixed on the second support.

[0009] Further, the third support is fixed on the web of the longitudinal outer frame steel beam and the flange of the core tube steel column. The attachment plate close to the core tube steel column is fixed on the third support.

[0010] Furthermore, it further includes a reinforcing tie rod, and reinforcing plates are provided at both ends of the reinforcing tie rod; one end of the reinforcing tie rod is fixed to the attachment tie rod through a fourth support member, and the other end is fixed to the web of the longitudinal outer frame steel beam through a fifth support member; the reinforcing tie rod is parallel to the transverse outer frame steel beam.

[0011] Beneficial effects:

[0012] The utility model provides a tower crane attachment structure. An attachment frame is arranged between the tower crane and the outer frame steel beam, an attachment tie rod is arranged between the outer frame steel beam and the core tube wall, and a reinforcing tie rod is arranged between the attachment tie rod and the outer frame steel beam, forming multiple stable triangular structures in the same horizontal plane, so that the supporting force of the tower crane is transmitted to the core tube wall through this structure, ensuring the stability of the tower crane attachment and the balance of the tower body steel structure. Moreover, the tower crane attachment is divided into an attachment frame, an attachment tie rod, and a reinforcing tie rod, greatly shortening the part of the attachment frame. There is no influence of the attachment frame structure in the core tube structure, avoiding the problem of hindering the construction of the floor operation surface caused by the too long attachment frame, and also reducing the material cost. When the construction is completed, the attachment frame in this structure can be quickly removed, saving the construction period. Brief description of the drawings:
