Embodiment Construction
[0031] The installation method of the large-span welded ball net frame provided by the present invention includes the following steps:
[0032] a, in such as figure 1 Four slides 1 are set in the rectangular construction area shown, which are named as the first slide, the second slide, the third slide and the fourth slide. The four slides are all parallel to the long axis of the construction area. The middle part of the construction area is provided with two arched sliding tire frames 2, and the vertical plane where the sliding tire frames 2 are located is perpendicular to the slideway 1.
[0033] like image 3 As shown, the sliding tire frame 2 includes an arch frame and four supporting legs, and the four supporting legs respectively correspond to four slideways, which are successively named as the first supporting leg 4, the second supporting leg 5, the third supporting leg 6 and the fourth supporting leg 7. There are rollers at the bottom of each support leg, so as to rea...

The invention relates to a method for installing a large-span welded ball grid. The method is to divide the grid structure into several grid units, each span unit is installed with a sliding tire frame as a construction platform, and the arch frame of the sliding tire frame and the The two side support legs are made of grid unit material. By replacing the rods on the side support legs, the side support legs can be opened outwards, so that the angle between the side support legs and the arch frame can be increased to the same The truss units are of the same size and are then used as truss units at the ends of the arched trusses. The two middle support legs are composed of the main material of the gable grid frame and some measure rods. After the main body of the grid frame is installed, the middle support legs are rotated 90° and assembled on the gable wall. The measure rods are cut off and utilized, thus greatly It saves the amount of measures and materials, and also reduces the workload of dismantling the sliding tire frame, and greatly reduces the labor intensity and construction cost.
Description
technical field [0001] The invention relates to a method for installing a welded ball net frame, in particular to a method for installing a large-span welded ball net frame. Background technique [0002] Welded ball grid is a grid structure with a wide range of applications. It can be used not only in industrial buildings such as warehouses and factories, but also in public buildings such as gymnasiums, theaters, terminal buildings, and station waiting halls. The long-span welded ball net frame is widely used in coal, electric power, cement, steel and other industries. Due to the relatively large specifications of the rods and balls of the long-span net frame, and because of the large span and high construction height, its joint form It is also a soldered ball joint, which puts forward higher requirements for the overall stability and installation quality of the grid during installation. [0003] At present, the methods used to make large-span welded ball grids mainly inclu...
