Circulating mutual-climbing lifting column and application method thereof

Abstract

The invention provides a circulating mutual-climbing lifting column which comprises a lower supporting frame. The lower supporting frame comprises bearing trusses; connecting trusses are fixedly connected to the positions, close to the tops and the bottoms, between the front faces and the back faces of the two bearing trusses; tower column connecting beams are fixedly connected to the positions, close to the two ends, between the bottoms of the two bearing trusses; bearing telescopic girders are slidably connected to the tops of the bearing trusses; and connecting plates are fixedly connected to the top faces of the bearing trusses. According to the circulating mutual-climbing lifting column provided by the invention, mutual climbing of an upper supporting frame and a tower column can be realized by adjusting the number of the supporting frames and the number of hydraulic jacking systems according to actual conditions, the height of a free cantilever of the tower column can be reduced, the wind resistance can be improved, and meanwhile, the input amount of the tower column can be saved; layer-by-layer jacking of the upper supporting frame and the tower column is achieved through stretching and retracting of a hydraulic oil cylinder, so that the jacking time is short, and construction is not affected; and overall lifting can be achieved through a platform arranged on the lower supporting frame, and multi-working-condition operation can be conducted on an embedded part system, the hydraulic jacking systems and the like on the platform, so that higher efficiency, higher economical efficiency and higher safety are achieved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a circular inter-climbing lifting column and a method for using the same. Background technique [0002] At present, in the field of building construction, especially in the construction process of super high-rises, bridge H-shaped towers, dams, etc., with the rapid development of society, new techniques and new equipment are gradually increasing, and the requirements for construction are gradually increasing. In order to meet the construction needs , More and more construction sites are beginning to use hydraulic self-climbing formwork, top formwork, self-climbing tower cranes and other equipment to solve the problems of high structure, heavy tower crane tasks, high labor costs, and large amount of pouring. But the following problems still exist: [0003] The use of hydraulic self-climbing formwork in the construction process of super high-rise building...

AI Technical Summary

Problems solved by technology

[0003]The use of hydraulic self-climbing formwork has been very mature in the construction process of super high-rise buildings, bridge H-shaped towers, dams, etc. The hydraulic self-climbing formwork is mainly composed of load-bearing tripods, It is composed of upper and lower frames, guide rails, hanging seats, embedded parts system, formwork system, backward moving device, hydraulic system and multi-layer operation platform; under construction and climbing conditions, at least two layers of hanging seats are guaranteed to be attached, and one layer of hanging seats Reverse use, but the hanging seat needs to be reversed manually, which is troublesome and has potential safety hazards; the power system of the hydraulic self-climbing formwork---the hydraulic system also needs to be manually reversed to the next layer for turnover use; and the general jacking force will not be too high Large, generally below 20T, in order to ensure the safety of the jacking and realize the overall lifting, there are many machine positions, the control is difficult, and there are many safety hazards;

[0004] Moreover, in super high-rise construction, more and more technologies such as self-climbing tower cranes are used. Generally, internal climbing tower cranes are widely used and are a kind of The tower crane in the elevator shaft and stairwell inside the building, or it can also be used as an internal climbing tower after transformation; during the climbing process, the supporting beam needs to be disintegrated in the air, transported and installed to the predetermined floor, so as to realize the climbing of the tower crane. During the process, it is necessary to use other tower cranes to cooperate with the lifting, which reduces the utilization rate of tower cranes and construction efficiency. On the whole, conventional reverse climbing has disadvantages such as large safety hazards, low efficiency, and difficult quality control.

[0005]In the existing construction process, self-climbing tower cranes have been widely used on site, but the existing self-climbing tower cranes need to frequently reverse the supporting beams to realize the self-climbing function of the tower crane , in the process of unloading, it is necessary to rely on hoisting equipment such as tower cranes on the construction site, which reduces the utilization rate of tower cranes and construction efficiency, and also increases many safety hazards; safety hazards are large and efficiency is low;

[0006]In the current construction process, most of the embedded parts cannot be turned over, the turnover rate of embedded parts is low, and the economic benefits are poor;

[0007]In the existing construction process, the self-climbing tower crane support beam was not transported in time. During the construction process, the free cantilever height of the tower crane was too high, the height of the tower body was large, and the wind resistance The problem of low capacity, poor economy and safety;

[0008]In the existing construction process, most self-climbing tower cranes have multiple layers to climb once, the climbing period is long, the construction efficiency is low, and the construction progress is affected;

[0009]In the existing construction process, operations such as dismantling and assembling of embedded parts, dismantling and assembling of supporting beams, and adjustment of frame body are performed without a platform, and the construction efficiency is low. Great safety hazard;

[0010]In the existing construction process, most of the operating equipment is only suitable for structures with fixed cross-sections. In the case of sudden changes in wall thickness, secondary dismantling of the frame is required. Increase the risk of high-altitude operations, low construction efficiency, and great potential safety hazards
