Safety protection method for precast beam construction

Abstract

The invention discloses a safety protection method for precast beam construction. The safety protection method comprises the following steps that three vertical steel bars which are distributed in a triangular shape and are equal in height are selected at one end of a precast beam; the three vertical steel bars are regarded as three vertexes of a triangle, and a fixed sleeve and two movable sleeves are adjusted according to the layout of the three vertexes; a first adjustable connecting piece and the corresponding movable sleeve are pushed to move transversely; the first adjustable connectingpiece is locked below a connecting seat through a first fastening bolt; a second adjustable connecting piece and the corresponding movable sleeve are pushed to transversely move or / and horizontally swing; the second adjustable connecting sheet is locked below the connecting seat through a second fastening bolt; the three vertical steel bars are correspondingly sleeved with the fixed sleeve and themovable sleeve; and a safety rope is connected between two protective vertical rods. According to the safety protection method, stable protection can be achieved, and the protection strength is higher.

Description

technical field [0001] The invention relates to a prefabricated beam construction protection method, in particular to a safety protection method for prefabricated beam construction. Background technique [0002] In the existing large-scale construction sites, the main building components (such as prefabricated beams) are generally prefabricated in the factory, and then transported to the site for overall assembly, which can save the step of pouring concrete on site, increase the construction speed, and also The number of on-site workers and equipment can be reduced, saving costs. [0003] After the prefabricated beams are transported to the construction site, the prefabricated beams are hoisted to the predetermined position by a large crane, and after the main body of the building is overlapped, the workers move to the prefabricated beams for subsequent construction. Among them, the prefabricated beams after lapping are higher than the ground. In order to ensure the persona...

AI Technical Summary

Problems solved by technology

[0005] 1. Since the fixed pole is directly set on the exposed vertical steel bar of the prefabricated beam, and there is no other fixing connected with the vertical steel bar, it may shake during the construction process, posing a safety hazard

[0006] 2. Since the fixed poles on both sides cooperate one-to-one with the steel bars, the protection strength only depends on the bending resistance of a single steel bar, and the protection strength needs to be improved
