High-altitude bulk process of bolt ball net frame

Abstract

The invention discloses a high-altitude bulk process of a bolt ball net frame, comprising the steps: 1) erecting local scaffolds; 2) assembling square pyramidal units on the ground; 3) carrying out local assembly of the net frame on the local scaffolds and forming a net-frame start crossing unit; and 4) assembling the start crossing unit by adopting lifting equipment, wherein the lifting equipment is fixed to the start crossing unit; the square pyramidal units are lifted to high altitude by the lifting equipment and are symmetrically overhung, expanded and assembled from the middle of the net-frame start crossing unit to the two sides thereof till the assembly of the whole bolt ball net frame is finished. The high-altitude bulk process provided by the invention is applicable to installation and construction of various large-span bolt ball net frame roof structure systems; and according to the high-altitude bulk process, large construction machines are not needed, the operation is simpler, and only few supporting scaffolds need to be erected, thus greatly improving the labor efficiency and reducing the labor intensity.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a high-altitude bulk packing process of a bolted ball net frame. Background technique [0002] The high-altitude bulk technology of bolt ball net frame is a relatively common construction technology of steel structure net frame at present. This technology usually uses steel pipe scaffolding to build a full house net frame to assemble the membrane, and the construction personnel install the grid on the full house membrane frame. The high-altitude bulk method is simple and convenient to operate, fast in construction, saves labor, can reduce on-site welding, reduces pollution to the surrounding environment, and can better ensure project quality in special working environments that do not have large-scale mechanical hoisting and overall lifting conditions on site , reduce engineering costs, realize energy saving and emission reduction and green construction.

AI Technical Summary

Problems solved by technology

[0010] 1. The assembled scaffolding of Mantang net frame not only needs to occupy a large amount of turnover materials, but also requires a large amount of scaffolding and dismantling, and the construction period is long

[0011] 2. The erection of full hall scaffolding for grid construction requires sufficient foundation bearing capacity. For the floor slabs of venues and competition halls, the design floor bearing capacity cannot meet the self-weight of the full hall frame body and the construction load of the upper grid. It is necessary to increase support at the bottom layer and consume more Turnover materials and costs

[0012] 3. All grid materials need to be hoisted to the full scaffolding. Measures should be taken to prevent the rods from rolling and falling when the rods and bolt balls are scattered and stacked on the plane, which poses a great safety hazard
