Embodiment Construction

[0009] Below with reference to accompanying drawing, the present invention is further described

[0010] The present invention is a tower crane fixed structure with external attachment and internal installation, which mainly includes four building core tubes 1, and is characterized in that: a patio 2 is formed in the center of the four building core tubes 1, and a patio 2 is provided inside the patio 2 The tower crane 3, the tower crane 3 is fixedly connected with the building core tube 1 through the wall-attached rod 4, this design scheme can change the original boom crane into a flat boom crane, which reduces the rental cost and saves the tower crane Climbing costs.

[0011] In actual implementation, installing a 1,100-ton-meter flat-arm tower crane in the patio can fully realize the hoisting requirements proposed in the project. The tower crane attached to the wall is just like the external tower crane, just attached to the pillars of the two core tubes.

[0012] The above...

Abstract

The invention discloses an attached built-in tower crane fixing structure. The attached built-in tower crane fixing structure is characterized in that centers of four building core tubes form a courtyard; a tower crane is arranged inside the courtyard; the tower crane is fixedly connected with the building core tubes through a wall attaching rod. In practical use, a tower hoist is saved for a general contracting unit, a crane is used at the same time, and the rental price of the crane is 70-80% of that of a jib crane. By changing the scheme, over 60% of cost can be saved for the project on the rental price of the tower; meanwhile, the internally climbing cost is also saved, and the tower crane fixing structure has good practicability.

Description

technical field [0001] The invention relates to the technical field of mechanical construction, in particular to a fixed structure of a tower crane with external attachment and internal installation, and particularly relates to its mechanical connection structure. Background technique [0002] The commercial building under construction is a combination of core tube and steel structure. The floor plan is as follows: figure 1 As shown in , it consists of four core tubes, the periphery of which is a steel structure, the middle area of ​​the four core tubes is the patio of a commercial building, and a sun shed is hoisted on the large roof. The construction general contractor intends to use two boom cranes of about 1,000 tons to complete the construction of the main structure when bidding for equipment. The location is close, and a flat-arm crane or a flat-head tower crane is arranged to form interference and pose a safety hazard). [0003] Therefore, it is necessary to propose...
