Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, a method for erecting a formwork bent frame of a cantilevered structure comprises the following steps:

[0033] S001: The steel support structure is spliced ​​on the ground, and each steel support structure includes a cantilevered main steel beam 10 and two diagonal braces 40.

[0034] S002: Install embedded parts on the structural beams of the Nth and N-1st floors of the building structure, where N is a natural number greater than 1. In the erection construction of the cantilevered formwork in this embodiment, N is equal to 12.

[0035] S003: Hoist the steel support structure, weld and fix the steel support structure with the embedded parts in step 2, one end of the diagonal brace 40 is fixedly connected with the cantilevered main steel beam 10, and the other end of the diagonal brace 40 is connected with the The structural beam embedded parts are fixedly connected.

[0036] S004: Embedding lifting rings (not shown) on the s...

Abstract

The invention relates to an erecting method of a cantilever structure formwork bent and belongs to the technical field of building construction. The problem that an existing cantilever structure formwork bent is difficult to erect and high in construction cost is solved. The erecting method comprises the steps that a cantilever platform steel supporting structure is spliced and welded on the ground at first; an embedded part is arranged on a building structure beam in the high altitude; the steel supporting structure is hoisted and is welded and fixed to the embedded part, thereby being fixed to a building structure floor beam; a reinforcing measure is provided, a hoisting ring is embedded on a sealing beam above the cantilever main steel beam to fix an upper pull rod, and the lower end of the upper pull rod is connected with the cantilever main steel beam in the steel supporting structure; auxiliary beams are laid above the cantilever main steel beam at intervals, finally, the gaps between the auxiliary beams are filled with square pillars and covered with a formwork, and therefore construction of a cantilever platform is completed; an operator erects a bent system composed of horizontal rods and vertical rods on the cantilever platform and carries out reliable pulling, and therefore the cantilever structure formwork bent is formed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for erecting a formwork bent frame of a cantilevered structure. Background technique [0002] In recent years, in order to achieve the effect of highlighting the effect of building facade modeling and the expansion of high-rise upper space in architectural design, more and more building constructions of high-rise cantilevered concrete structures and components have been carried out. Since the self-weight of the cantilevered concrete structure is much greater than the weight of the steel structure and other components, it brings certain difficulties to the design and construction of the formwork bent of the cantilevered structural components. There are relevant specifications and standards for formwork bending in my country, but there is no relevant technical standard for cantilevered formwork bending erected at high altitudes. [0003] Currently, the exist...
