Construction method for continuous type hanging net rack platform for hyperbolic reticulated shell venue

Abstract

The invention discloses a construction method for a continuous type hanging net rack platform for a hyperbolic reticulated shell venue. The construction method comprises the following steps that firstly, a topological structure of the continuous type hanging net rack platform is determined; secondly, a safety net is installed; thirdly, a temporary console of a starting point type net rack platformunit is built; fourthly, the starting point type net rack platform unit is installed; fifthly, the next net rack platform unit is installed; sixthly, protection rods and a safety lock are installed on the next net rack platform unit; seventhly, the fifth step and the sixth step are performed repeatedly till construction is completed; and eighthly, all the net rack platform units are dismantled. According to the construction method, the multiple net rack platform units are hung on a top chord at the top of the hyperbolic reticulated shell venue, the multiple net rack platform units can form the topological structure and can be expanded in any direction, the next net rack platform unit can be constructed on the last net rack platform unit, the construction and dismantling process is convenient and fast, and use and popularization are convenient.

Description

technical field [0001] The invention belongs to the technical field of grid operation platforms, and in particular relates to a construction method for a continuous hanging grid platform for hyperbolic grid shell venues. Background technique [0002] At present, there are two ways to install the electromechanical equipment on the top of the hyperbolic reticulated shell venue. The first is to use the traditional construction method: after the grid frame is erected, the full hall frame is set up in the venue, the electromechanical equipment is installed, and the full hall frame is removed. However, the full hall frame The erection construction period is long, the process is cumbersome, the volume is large, and the pre-construction preparation cost is high; the second method is: use the crank arm truck to move below the installation point of the grid structure, which requires professionals to operate machinery and high-altitude operations, but Due to the hyperbolic reticulated ...

[0002] At present, there are two ways to install the electromechanical equipment on the top of the hyperbolic reticulated shell venue. The first is to use the traditional construction method: after the grid frame is erected, the full hall frame is set up in the venue, the electromechanical equipment is installed, and the full hall frame is removed. However, the full hall frame The erection construction period is long, the process is cumbersome, the volume is large, and the pre-construction preparation cost is high; the second method is: use the crank arm truck to move below the installation point of the grid structure, which requires professionals to operate machinery and high-altitude operations, but Due to the hyperbolic reticulated shell structure, the working surface is uneven, and the internal structure of the steel grid is complex. The operating platform of the articulated arm vehicle cannot reach the designated position in the steel grid. It is necessary to further build an operating platform at the lower chord of the steel grid before installation. construction

Moreover, the post-maintenance of the above two methods is still difficult. If the first method is used, the full hall needs to be erected again for each maintenance, and the maintenance cost is high; to the scene
