Description
Technical Field
The invention relates to the field of building construction.
Background
In the construction process of high-rise buildings, a horizontal protective net for receiving falling objects is required to be additionally arranged on the outer side of the scaffold along a certain height. Usually, the protective net is a large mesh net body formed by weaving fiber ropes in a staggered manner, and the periphery of the large mesh net body is connected with a steel pipe and accessories thereof.
Because the risk of the operation of erecting the horizontal protective net outside the scaffold is higher, and according to the higher requirement of the protection enhancement of the falling object protective net, the common large-mesh net body needs to be changed into the falling object protective net with stronger bearing force, the weight of the falling object protective net and the erecting area of the falling object protective net are correspondingly increased, and the risk is higher undoubtedly by adopting the traditional protective net erecting mode.
To solve this problem, we consider improving the way of building a rack by assembling the falling object protection net and its net hanging rod in the floor or in the rack, and then extending it outward in the horizontal direction until it reaches a predetermined position. However, because the area and the weight of the novel falling object protective net support are large, the falling object protective net located on the side face of the same building is difficult to be expanded outwards at one time. Therefore, we further consider that the falling protection net is expanded outwards in sections, which requires that the butt joint connection between two adjacent net hanging rods of the external net cannot be a rigid connection, but should be a flexible connection, i.e. the adjacent net hanging rods need to be capable of bending and can adapt to the sliding of the axial length of the net hanging rods, so that the outward expansion of the falling protection net in sections can be realized. In order to meet the requirement of the working condition, a net hanging rod ectopic movable hinged support for safely erecting a falling object protective net and a horizontal rotating mechanism thereof need to be designed.

Preferably, the left platform and the right platform are symmetrically arranged at the left side and the right side of the middle seat body.
Preferably, the left platform and the right platform are fixedly connected with the middle seat body; or the middle seat body, the left platform and the right platform are integrally formed.
Preferably, the horizontal rotating mechanisms are symmetrically arranged on the left platform and the right platform and are located at positions far away from the middle seat body.
Preferably, the collar and collar seat are of integrally formed construction.
The invention has the advantages that: according to the invention, the middle base body with the left platform and the right platform is used as the connecting main body, the horizontal rotating mechanisms are respectively arranged on the left platform and the right platform and are respectively sleeved with the two adjacent net hanging rods, so that the flexible connection between the two adjacent net hanging rods is realized, namely the two adjacent net hanging rods can be bent by using the horizontal rotating mechanisms and can axially slide along the lantern ring, the problem of mechanical interference generated when the two net hanging rods are expanded in a segmented manner is solved, and the segmented outward expansion of the falling object protection net is favorably realized.
