Method for mounting overall steel protective shed cantilever frame

Abstract

The invention discloses a method for installing a pick frame for an integral steel protective shed, which comprises the following steps: using a steel bar ring pre-buried on the outer beam of the main structure floor, and then using a temporary pick frame outside the lower floor to install and fix the I-beam, The beam is fixed to the edge of the cantilevered steel through a reinforcement ring, and then the channel steel is welded with a hydraulic adjustable support rod as a diagonal brace, and the assembled hinge components at both ends of the diagonal brace are connected and fixed; the I-beam on the ground is welded with a short The steel bar head is laid with steel plates on the adjacent I-beams. The surface of the steel plates is welded with multiple steel bars to form reinforcing ribs. The outer scaffolding poles are inserted on the short steel bar heads to form the outer protective frame of the building. Horizontal long steel pipes and vertical short steel pipes are erected to form For the protective shed, the vertical short steel pipes are inserted on the short steel bars, the horizontal long steel pipes are covered with bamboo scaffolding boards, and the protective railings are set outside the protective shed. It is safe, economical and fast to use the tower crane to hoist the prepared double-layer protective shed into place. It does not need the ground and solid foundation as support. The supporting capacity of the cantilevered steel beam is greatly improved by the secondary cable-stayed unloading of the high-strength steel wire rope.

Description

technical field [0001] The invention relates to a method for installing a pick frame, in particular to a method for installing a pick frame for an integral steel protective shed. Background technique [0002] In the installation process of the existing protective shed canopy, the high-strength steel wire rope is used for secondary cable pull to unload, which is a potential source of danger for the person falling from above, because when the person above falls from a high altitude, the falling speed is very fast, and the steel wire rope , secondary damage will occur, which is also a problem in the current security flat net setting. [0003] The existing load-bearing components of the protective shed are complex and the cost is too high. It takes a long time for the embedded parts to fully meet the strength requirements from the embedded parts to the concrete, which is not suitable for the flow requirements of the construction progress. The installation process requires tower ...

Problems solved by technology

[0003] The existing load-bearing components of the protective shed are complex and the cost is too high. It takes a long time for the embedded parts to fully meet the strength requirements from the embedded parts to the concrete, which is not suitable for the flow requirements of the construction progress. The installation process requires tower crane hoisting, which also increases Machinery cost
