Background

At present, the government is greatly developing assembled buildings, so that the development of assembled steel structures is rapid. But the construction speed of the assembled steel structure is high, and an operation scaffold is generally not erected in the construction stage. After the steel beam and the steel column are temporarily fixed, an operator is required to connect the steel column with the section steel beam node to the top of the steel beam, and the connection construction belongs to the field of high-altitude operation construction.

The existing connection construction of the steel column and the section steel beam joint adopts the following two methods:

the first is to use a crank arm vehicle for construction. The method is only suitable for the working condition that the field is relatively flat, and when the field condition is complex, the crank arms Che Yi are overturned. Furthermore, the crank arm vehicle is limited by height and space, and cannot be used when the height limit value is exceeded; when the floor slab at the bottom layer is installed, the floor slab can cut off the lifting space of the crank arm vehicle, so that the beam column joints at the higher layer cannot be constructed. In order to solve the problems of the first method, there is a second method of fixing the posts 12 to the steel beam 11 by bolts and installing safety ropes 13 between the posts 12. The operator hangs the seat belt on the safety rope 13 for an overhead operation (as shown in fig. 1).

The second method has the following disadvantages:

1. the distance between the upright posts is required not to be too large, otherwise, the safety rope is in a loose state, and the safety guarantee is poor;

2. the installation of a plurality of upright posts is labor-consuming and time-consuming, the turnover efficiency of the spare parts is low, and the cost and the construction period are not controlled;

3. a pair of hanging basket operating platforms are hung on a steel beam, and workers stand in the platforms to perform wall surface operation. And the worker needs to move the hanging basket at any time according to the construction position at any time, but the upright post can obstruct the movement of the hanging basket, so that the construction efficiency is greatly influenced.
