The technical scheme adopted by the invention for solving the technical problem is to provide a using method of the steel beam mounting and lapping device, which comprises the following steps:
(1) prefabricating an L-shaped support member and a T-shaped support member in a factory, and welding and fixing the L-shaped support member on a bracket of a steel column;
(2) after the steel column is installed on site, the T-shaped supporting piece is inserted between the two L-shaped supporting pieces with the inner openings opposite to each other on one side of the bracket;
(3) hoisting the steel beam in place by using hoisting machinery;
(4) inserting the T-shaped support part between the two L-shaped support parts with opposite inner openings on the other side of the bracket in a socket mode, and stably placing the steel beam on the T-shaped support parts on the two sides;
(5) unloading and unhooking the hoisting machinery to hoist the next station;
(6) carrying out position adjustment and connection construction on the steel beam;
(7) and (5) removing the T-shaped support for repeated recycling.
Advantageous effects
Firstly, the invention can provide reliable bearing force for the steel beam which is hoisted in place, can realize timely unhooking of the hoisting machinery before adjustment and connection construction of the steel beam and transfer to the next hoisting operation, can improve the use efficiency of the hoisting machinery, is beneficial to shortening the construction period and reducing the construction cost. In the existing steel beam mounting method, after the steel beam is hoisted in place, due to the fact that the steel beam does not have reliable bearing points, the hoisting machinery cannot be unloaded and unhooked, and the hoisting machinery can only unhook the steel beam after the steel beam is adjusted and mounting bolts are completely penetrated to perform the next operation
Secondly, the device can be recycled, so that a large amount of steel is not wasted, and the cost is not greatly increased; the invention is realized through the socket structure, welding and cutting are not needed in a construction site, the base metal is not damaged, the quality is not reduced, and the potential safety hazard of extra firing operation and overhead operation is not brought.
