[0002] A gymnasium is a large building used for sports competitions, physical exercises, concerts and other activities. The top or periphery of the gymnasium is generally supported by a steel grid structure. With the rapid development of the economy, large-span grid structures are increasingly used in construction projects. The steel structure of a large gymnasium roof is a new type of steel structure with reasonable force, light weight, low cost, lively and novel appearance, good stability and safety. The existing high-altitude scattered assembly method of the steel structure of a large gymnasium roof is relatively traditional, which is not only cumbersome and complicated, but also troublesome to construct and has poor safety. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for high-altitude loose assembly and installation of a large gymnasium roof steel structure, which simplifies the construction steps, is easier to implement, and has better safety.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A method for high-altitude assembly and installation of a large gymnasium roof steel structure comprises the following steps:

[0006] A. Install the outer frame of the gymnasium steel structure. First install the crossbeams and longitudinal beams to ensure the correct installation position and angle. Then install the columns and vertical supports to ensure the appropriate installation height and distance. When installing the outer frame, you need to use tools such as cranes to lift the steel structure to the correct position.

[0007] B. After the installation of the outer frame is completed, the inner frame of the gymnasium steel structure is installed. The purpose of this step is to strengthen the outer frame and support the weight of the roof. When installing the inner frame, attention should be paid to the distance and position around the pipes and cables to ensure that the inner frame will not affect the pipes and cables.

[0008] C. A safety circle of tracks is fixed on the top of the outer frame and the inner frame, and a number of track flat cars that can circulate freely are installed on the tracks;

[0009] D. Install the hoisting machine on all rail flat cars, move the rail flat cars flexibly on the tracks, and then operate the hoisting machine to hoist the steel structure parts of the large gymnasium roof one by one to the appropriate position and height and complete the installation. Assemble small units or components at the designed position, use computer synchronous measurement and control and wireless remote control system technology to dynamically monitor the working status of the hoisting machine and control it at any time to ensure construction safety. After completing the high-altitude loose assembly installation of the large gymnasium roof steel structure, all equipment will be removed.

[0010] Preferably, a plurality of fixing points are provided on the track to prevent the track flat car from deviating during use.

[0011] Preferably, a GPS positioning system is installed on the rail flat car so that the rail flat car can be found quickly when needed, thereby improving work efficiency.

[0012] Preferably, a braking force device is installed on the rail flat car, and when the flat car deviates, the flat car can be braked immediately to keep it on the predetermined track line.

[0013] Preferably, the rail flat car is provided with a track guide system so that the rail flat car can only travel within a predetermined track range, thereby avoiding deviation.

[0014] Preferably, a limit switch is provided on the track. When the rail flat car exceeds a certain deviation range, the limit switch will send a signal to cut off the power of the rail flat car, so that the rail flat car stops moving, thereby avoiding deviation.

[0015] Preferably, the outer frames are all made of stainless steel rods installed by means of screws, nuts and mounting brackets.

[0016] Preferably, the inner frames are all made of stainless steel rods installed by means of screws, nuts and mounting brackets.

[0017] Preferably, the rail is made of stainless steel.

[0018] Preferably, the rail flat car is a diesel internal combustion vehicle.

[0019] Compared with the prior art, the present invention provides a method for high-altitude loose assembly and installation of a large gymnasium roof steel structure, which has the following beneficial effects:

[0020] The high-altitude scattered installation method of the steel structure roof of the large gymnasium adopts a simplified 4-step construction method. It is not only simple and convenient to operate and improves construction efficiency, but also uses computer synchronous measurement and control and wireless remote control system technology to dynamically monitor the working status of the hoisting machine and control it at any time. At the same time, through optimized design, it can timely detect whether the rail flat car is offset and take countermeasures to ensure construction safety.
