Description

TECHNICAL FIELD

[0002] The portal rigid frame structure of the building industrial plant adopts the door type rigid frame structure of multiple-span continuous beams according to the process design requirements, and the conventional installation mode is as follows: at least two cranes are used to hoist a single I-beam (large section inertia moment) as a lifting tool steel pole, each hoists a single-span beam to be in place after high-altitude alignment, and then the high-strength bolts of the beams and the beams and the beams and the columns are respectively connected. The current method uses at least two cranes to hoist a single I-beam as a lifting tool to hoist a single-span beam to be in place after high-altitude alignment, and then the beams and the beams and the beams and the columns are connected. This method requires multiple cranes to cooperate, it is difficult to hoist in place at high altitude, the installation deviation is large, and it needs to be adjusted repeatedly. The single I-beam lifting tool is not enough to bear the load and is easy to bend and lose stability, it is not economical to hoist multiple-span continuous beams (it is not economical to increase the section size), the quality of the superimposed and combined welding is not easy to guarantee and is not economical, the personnel at high altitude need to operate a wide range of processes for a long time, the safety risk is high, and the smooth progress of the installation construction progress, quality and safety targets is affected.

[0003] In order to solve the problem of bending of the single I-beam lifting tool, a double-row pole beam lifting tool is proposed in Chinese patent CN203359759U, which includes two H-shaped steels and two lifting lug plates. The two H-shaped steels are used to stabilize the overall lifting tool, and the two lifting lug plates are used to fix and connect the two H-shaped steels. Chinese patent CN118723779A also proposes a structural type combined crane beam, which is composed of two crane beams and a space truss between them to form an overall space structure, so that the two crane beams can jointly resist external loads. However, the part without the fixing of the lifting lug plate in the double-row arrangement is still weak in stress, the overall stability is not the same, and there is still a certain safety risk.
