High-altitude tower crane non-floor single row frame adhering structure and construction method thereof

Abstract

The invention provides a high-altitude tower crane non-floor single row frame adhering structure which comprises two bottom columns and two frame columns, the bottom columns are reinforced concrete columns, which are close to the tower crane, on the outermost of a building body, the frame columns are arranged one one sides, close to the tower crane, of the bottom columns and formed by buttress column reinforcement cage pouring concrete, and a tower crane adhering mechanism is arranged on the front surfaces of the upper parts of the frame columns; the buttress column reinforcement cage comprises at least four frame column main reinforcement bars; 1-3 X-shaped inclined struts and at least one frame beam are arranged between the two frame columns. The structure can efficiently meet the high tower crane safety construction hoisting height control high requirement. A construction method of the adhering structure is further put forward and comprises the steps that 1, two reinforced concretecolumns close to the tower crane are taken as the bottom columns; 2, embedded steel bar construction of the frame column main bars is performed; 3, the frame column main bars are connected with otherrebar to form the buttress column reinforcement cage, and a frame beam reinforcement cage is mounted; 4, concrete construction of the frame columns and the frame beam is performed; 5, the X-shaped inclined struts are mounted. According to the method, the damage to the building structure is small, the construction period is short, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an attachment frame using a reinforced concrete column of a building as the attachment base of a tower crane and a construction method for the attachment frame. Background technique [0002] Some existing large-scale factory buildings usually adopt reinforced concrete structural frame and grid (that is, profiled steel plate) structure roof, and each floor is high, so the tower crane used in the construction process is usually based on the reinforced concrete columns of the factory building and The reinforced concrete buttress columns above it (that is, single-row frame structure without floor slab) are attached structures. During the construction process of the factory building, the design requirements sometimes change. When the total height of the factory building becomes higher, the lifting height of the tower crane will increase accordingly. Lifting height contr...

AI Technical Summary

Problems solved by technology

During the construction process of the factory building, the design requirements sometimes change. When the total height of the factory building becomes higher, the hoisting height of the tower crane will increase accordingly. Lifting height control is highly demanding, but since this design change occurred during the construction process, the tower crane foundation and tower crane have been installed and put into construction, the existing tower crane attachment structure and attachment points can no longer meet the construction needs in terms of height and strength , if the tower crane foundation and tower cranes that meet the construction needs are reinstalled, the construction progress will be seriously affected and the construction cost will be increased; and if the existing tower cranes are abandoned and truck cranes are used for construction, the truck cranes need to be arranged near the road, and long-term occupation of the road will cause problems. Affects the transportation of materials throughout the project, thereby affecting the overall construction schedule
