Method for hoisting concrete T-shaped crane beam

Abstract

The invention belongs to the technical field of building operation lifting erection, and particularly relates to a method for hoisting a concrete T-shaped crane beam. Two electric winches and two fixed pulleys anchored onto second-layer concrete columns are adopted, a hoisting hole formed in a first-layer cast-in-place concrete top plate is also used, and the electric winches pull hoisting steel wire ropes to pass through the fixed pulleys and the hosting hole so that the concrete T-shaped crane beam can be lifted onto brackets of the concrete columns. The two electric winches in the hoisting process can achieve synchronous operation, and one of the electric winches can be controlled independently to be used for leveling the crane beam. The method for hoisting the concrete T-shaped crane beam is low in construction site requirement, technically feasible, safe and reliable, low in construction cost, short in construction period, wide in application range and thus suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of hoisting and hoisting in building construction, and in particular relates to a hoisting method of a concrete T-shaped crane beam. Background technique [0002] During plant construction, concrete T-shaped crane beams are usually hoisted by large hoisting machinery. Before the concrete T-shaped crane beam is hoisted, the driving route for the hoisting machinery to enter and exit the factory building should be flat and have sufficient bearing capacity, width and turning radius. Moreover, during hoisting operations, the foundation of the crane station on the construction site should be dense, and the outriggers should have a greater bearing capacity. When heavy machinery travels, the hoisting operation area requires not only flatness, but also sufficient bearing capacity, width and turning radius. Therefore, the hoisting method of the concrete T-shaped crane girder using hoisting machinery in the prior art...

Problems solved by technology

Regardless of the limited geographical location of the building, the general design of the ground in the building, and the limited depth of the building and the limited floor height of the building, it is impossible to meet the hoisting needs of the hoisting machinery construction site; so according to the conventional existing The hoisting method has certain difficulties in terms of safety and technology, and the cost is high and the construction period is long.
