In order to achieve the above object, the present invention is realized by:
a construction method for butting a pipe truss with a steel casting tongue-and-groove branch pipe during hoisting; comprises that
Step 1, a crane lifts a pipe truss to a high altitude, an upper chord is close to an upper chord of the installed pipe truss, a lower chord is close to a tongue-and-groove branch pipe of a steel casting, and the pipe orifice approach distance is about 100 mm;
step 2, installing a chain block at the upper chord butt joint, and installing a chain block at the lower chord butt joint;
and 6, installing a supporting jig frame top support to complete the positioning of the pipe truss frame, wherein the lifting hook can be hooked loosely.
Aiming at the defects of the existing construction, the construction method provides a construction method which needs to carry out high-altitude pipe orifice butt joint after the upper chord member and the lower chord member of the pipe truss are hoisted in a non-parallel way and the truss can be in place; the high-altitude posture of the truss is controlled through the chain block, so that the pipe truss can be conveniently installed and put in place as soon as possible, the installation efficiency is effectively improved, the mechanical shifts are reduced, the safety risk is reduced, and the construction efficiency is enhanced.
