Problems solved by technology

Another example is the demolition method disclosed in the Chinese patent application with application number 201610060325.8, which not only has the disadvantages of high accuracy requirements for horizontal direction control and limited number of lifting beams, but also requires "pre-removal of wood and formwork above the beams" and Welding is required, and the safety risk of the dismantling process is high

Embodiment 1

[0026] This embodiment further illustrates the construction method for demolition of high-rise building Bailey beams in conjunction with the accompanying drawings. The steps are:

[0027] In the first step, when pouring the load-bearing girder of the transfer layer, the two ends of the beam bottom correspond to the joints of the second and third units on one side of the Bailey beam and the pre-embedded joints above the joints of the first and second units on the other side. Hang the rooted first and second U-shaped hooks U-1 and U-2, and the distance between the outer sides of the first U-shaped hooks is less than the length of the Bailey beam standard section and greater than 1 / 2 the length of the Bailey beam standard section Embed the third U-shaped hook hanger U-3 at the position, and embed the fourth U-shaped hook at the position where the inner distance of the second U-shaped hook hanger is less than the length of the Bailey beam standard section and greater than 1 / 2 the ...

Abstract

The invention relates to a dismantling construction method of a high-rise building Bailey beam and belongs to the technical field of building construction. The method comprises all the following steps that a pre-buried piece is arranged; a force bearing crossbeam pouring template and a latticed column for supporting a Bailey beam are dismantled; the Bailey beam is hung in the vertical direction with the help of the pre-buried piece; single section Bailey beam bodies on the outer side of the Bailey beam are sectionally dismantled; a Bailey beam main body is gradually translated through lifting points; a winch is handled; and the Bailey beam main body is fallen, and finally, dismantling is completed. The dismantling construction method of the high-rise building Bailey beam has the obvious advantages that the dismantling construction method is not influenced by terrains, a lifting appliance is simple, operation is easy, construction cost is low, adaptability is high, efficiency is high, and safety is high.

Description

technical field [0001] The invention relates to a building transfer floor belay frame platform, in particular to a high-rise building transfer floor bere frame platform, and also relates to its construction method, which belongs to the technical field of building construction. Background technique [0002] High-rise buildings often need to build transfer floor beret platforms due to structural changes between floors. Although the Chinese invention patent documents with the application numbers of 201010135856.1 and 201410337666.6 respectively disclose the construction of high-rise building beam structure transfer layer construction and the method of Bailey beam suspension formwork support system construction, they are not perfect enough. The system is easily affected by construction loads and other deficiencies, so the applicant proposed a technical plan with the application number 201710326359.1 and the name "a construction method for a high-rise building transfer layer Bail...
