In order to solve the technical problems, the technical scheme of the invention is as follows: the utility model provides a build assembly lug structure on special, its innovation point lies in: including last body, bulkhead and lug of building, on build the body and include a plurality of bulkheads, the lug segmentation is fixed the bulkhead top can be directly through the lug matches wire rope and carries out the hoist and mount of building the body on, guarantees to build whole hoist and mount's intensity, and the installation step includes:
the method comprises the following steps: planning a lifting lug pattern on the premise of ensuring the integral hoisting strength of the upper building;
step two: modifying the top structure of the bulkhead, reserving a lifting lug mounting groove, and changing the lifting lug mounting groove into a lifting form;
step three: the lifting lugs are installed and fixed, and the lifting safety is guaranteed.
Furthermore, the lifting lugs comprise a first lifting lug, a second lifting lug, a third lifting lug and a fourth lifting lug which are reinforced through a toggle plate, and the stability and the structural strength of the lifting lugs are enhanced.
Furthermore, the first lifting lug is a straight-angle triangular structure formed by mutually and vertically connecting a first fixing surface and a first lifting surface, a plurality of first lifting holes are formed in the first lifting surface, the distances between every two adjacent lifting holes are equal, and the first lifting lug is fixed on the bulkhead through the first fixing surface.
Furthermore, the second lifting lug is a right-angled triangle structure formed by vertically connecting a second fixing surface and a second hanging surface, the second hanging surface is a trapezoid structure, a plurality of second hanging holes are formed in the second hanging surface, and the second lifting lug is fixed on the bulkhead through the second fixing surface.
Furthermore, the third lifting lug is a right-angled triangle structure formed by mutually and vertically connecting a third fixing surface and a third hanging surface, the third hanging surface is a chamfered rectangle structure, a plurality of third lifting holes are formed in the third hanging surface, and the third lifting lug is fixed on the bulkhead through the third fixing surface.
Furthermore, the fourth lifting lug is of a triangular structure and is fixed on the bulkhead through the third fixing surface.
The invention has the advantages that:
in the invention, a hoisting scheme is considered in the design stage of the built sectional drawing, part of the top structure of the bulkhead is modified, the structure is directly made into a continuous hoisting ring and is permanently reserved, the stability and the structural strength of the hoisting lug are enhanced through the toggle plate, the subsequent work of installing the hoisting lug is reduced, and the hoisting is carried out by using a simple steel wire rope configuration under the condition of ensuring the hoisting safety, so that the construction amount is reduced, and the hoisting risk is reduced.
