Description

Special fixture suitable for grid hoisting ball node Technical Field The utility model belongs to the technical field of building construction, and particularly relates to a special fixture suitable for a grid hoisting ball joint. Background The grid structure is a statically indeterminate structure, the structural system is stable, the steel consumption is economical, and the grid structure is widely applied to large-span public buildings, industrial plants and other buildings. The grid structure can be divided into a welded ball node grid and a bolt ball node grid according to the node type, and the common construction process for installing the two types of grid is hoisting. In the hoisting process, the ball node is a sphere, the steel wire rope cannot be bound, if the hoisting steel wire rope is bound on a connecting node of the rod piece and the sphere, the node is easily damaged by shearing force generated by hoisting, so that the structure is unstable, and serious potential safety hazards exist. If the lifting lug is welded and lifted on the ball node, the lifting lug is required to be removed through overhead operation in the later period, and the parent metal is easy to damage in the flame cutting process. Disclosure of utility model The utility model aims to provide a special fixture suitable for hoisting a ball node of a grid structure, which can ensure the safety of the hoisting process of the grid structure without damaging the ball node, a rod piece and a connecting node. In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a special fixture of rack hoist ball node, is circular shape base including the cross-section that is located ball node bottom, the centre both sides edge symmetry of base is equipped with the spacing board that is used for wire rope spacing, the radius of spacing board and ball node's radius assorted are equipped with the welt between the spacing board top that is located base and one side, the bottom both sides of base are equipped with the cardboard that the cross-section is the door font, the upper portion of cardboard is equipped with down the welt. Further, the inner diameter of the base is 1/2 of the outer diameter of the ball joint. Further, the height of the top of the limiting plate from the top of the base is 60mm, and the length of the limiting plate extending out of the base is 63mm. Further, the spacing between the limiting plates on the same side of the base is 60mm. Further, the upper lining plate is flush with the tops of the two limiting plates. Further, the clamping plates are symmetrically arranged relative to the center of the base. Further, the clamping plate is positioned at the bottom of one side of the base provided with the limiting plate. The beneficial effects of the utility model are as follows: 1. the utility model is convenient to detach and install and can be repeatedly recycled. 2. The utility model is safe and reliable, the clamp is arranged at the bottom of the spherical joint, the steel wire rope passes through the clamp, and under the dead weight of the net rack, the steel wire rope acts on the clamp, so that the clamp is tightly supported by the spherical joint, and meanwhile, the upper lining plate and the lower lining plate of the clamp can prevent the steel wire rope from damaging the spherical body.
