Problems solved by technology
[0002] Due to the increasing span of the existing venue buildings and storage buildings, in the past, the large-span grid roof was built with scaffolding as the construction operation platform, which was labor-intensive, with a long construction period and many hidden dangers; if it was hoisted by a crane, the mechanical cost would be high, and Due to uneven force, it is easy to cause deformation of the grid frame

Embodiment Construction
[0017] The construction method of large-span ball-node spherical grid group pulling rod hoisting includes the following steps: making small units and spreading and assembling them around, the first stage of lifting, outward assembly of spherical grids, installation of pulling rod clusters, and the second stage of lifting , the outward assembly of the spherical grid and the fixation of the spherical grid; among them, the first stage of lifting uses a tripod to lift the spherical grid, and the lifting height meets the installation height of the next row of lower chords and ball joints; pull out the cluster The installation includes leveling and compacting the site, making the steel pipe into a pulling rod, positioning the pulling rod, positioning and excavating the cable wind rope anchor pit, laying the cable wind ground anchor, correcting the pulling rod assembly, adjusting and tensioning the cable wind rope, and pulling the rod pulley block Installation and hoisting winch insta...

The invention relates to the technical field of lifting and hoisting, and in particular to a large-span ball joint spherical wire frame cluster rocker hoisting construction method. The large-span ball joint spherical wire frame cluster rocker hoisting construction method is characterized in that a rocker cluster is adopted, and multiple double-trolley groups (which are used for reducing the speed and reducing a tractive force) are suspended and are connected with slings in suspension points of a wire frame; a winch is used for combining tractive forces, the pulley groups drive the wire frame to move upwards synchronously, the whole wire frame is uniformly lifted to exceed the standard height of the top part of a column, a steel wire rope of one side winch is utilized to release slowly, the other side winch is locked to be in stillness, and the whole wire frame is moved to align to the top part of the column; then all winches are used for descending the wire frame to the top part of the column, and the wire frame is adjusted and fixed; assembling of the wire frame is carried out on the ground, the construction is simple, convenient and safe, the engineering quality is easy to control, the comprehensive benefit and the economic benefit are obviously increased, and the safety risks are reduced.
Description
technical field [0001] The invention relates to the technical field of hoisting and hoisting, in particular to a construction method for hoisting a large-span ball-joint spherical network frame group by pulling rods. Background technique [0002] Due to the increasing span of the existing venue buildings and storage buildings, in the past, the large-span grid roof was built with scaffolding as the construction operation platform, which was labor-intensive, with a long construction period and many hidden dangers; if it was hoisted by a crane, the mechanical cost would be high, and Due to uneven force, it is easy to cause deformation of the grid frame. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a construction method for hoisting large-span ball-noded spherical grid groups with rods. [0004] The present invention is realized by adopting the following technical scheme: the large-sp...
