A climbing formwork system with high lifting and large span

Abstract

The present invention discloses a high-lift and large-span climbing formwork frame system. The climbing frame structure has been re-arranged and integrated. Compared with the current structural form in which columns correspond to each other up and down and are connected in sequence, when the lifting force increases and the number of frames is reduced, the conventional climbing frame structure adds reinforcement in the middle, the reinforcement strength is too high, and materials are wasted too much. The climbing frame structure of the present application creates a new layout. By increasing the model of the upper frame platform beam on the top of the lower frame, an increased platform beam at the bottom of the upper frame is formed, and the upper frame columns are supported above the increased platform beam at the bottom of the upper frame, and the hanging frame columns are connected below to form an upper support and lower hanging structure. The hanging frame layer is changed from being located below the lower frame to overlapping the upper part with the lower frame, so that the upper frame columns and the lower frame columns can be flexibly staggered, so that the upper frame columns and the hanging frame columns of the entire climbing formwork can be reasonably arranged at intervals according to the load-bearing capacity, avoiding excessive reinforcement strength and excessive waste of materials, saving costs.

Description

Technical Field

[0001] The invention belongs to the field of climbing formwork equipment, and in particular relates to a climbing formwork frame system with high lifting and large span. Background Art

[0002] At present, there are more and more high-rise buildings and super-high-rise buildings, which are characterized by basically the same plan layout of the vertical walls of the core tube. The climbing system is used to carry the formwork together for the main construction, which has the characteristics of a high degree of mechanization. The higher the height of the high-rise and super-high-rise buildings, the more advantages the climbing formwork platform has.

[0003] The current climbing frame can refer to the patent with announcement number CN113550557A, which discloses a climbing formwork and hydraulic climbing formwork construction process for high-rise building construction, including guide rails and a climbing frame. The current climbing frame includes an upper frame body, a lower frame body and a hanging frame body. The formwork and the operating frame are installed on the upper frame body, and the jacking device is installed on the lower frame body. The jacking device cooperates with the guide rails to climb alternately, and construction operations can be carried out on the upper frame body, the lower frame body and the hanging frame body.

[0004] The structure of the frame is as follows: the frame includes a lower frame, an upper frame and a hanging frame. The lower frame includes a lower frame top beam, a lower frame inner column, a lower frame outer column, a lower frame bottom beam and a lower frame platform beam. The upper frame includes an upper frame platform beam, an upper frame column, an upper frame beam and an upper frame platform beam. The upper frame platform beam is fixed on the lower frame top beam in a horizontal direction parallel to the wall. The hanging frame includes hanging frame columns, hanging frame beams and hanging frame platform beams. The upper frame, the lower frame and the hanging frame are connected in sequence from top to bottom. The upper frame columns are fixedly installed on the lower frame top beam, the hanging frame columns are installed at the bottom of the lower frame bottom beam, and the upper frame columns, the lower frame columns and the hanging frame columns are directly connected.

[0005] The spacing of the inner columns of the lower frame is adjusted according to the building openings and obstacles. As the size of the building increases and the size of the openings and obstacles increases, the spacing of the columns of the lower frame of the climbing frame needs to be increased accordingly, and the overall width of the climbing frame needs to be increased to reduce the number of spliced ​​climbing frames. The jacking force also increases accordingly, forming a high-lift and large-span climbing frame. However, the spacing between the upper frame columns and the hanging frame columns increases accordingly, resulting in safety hazards. Therefore, the number of upper frame columns and hanging frame columns needs to be increased, and the increase in number will result in too small spacing, waste of materials and increased costs.
