Construction method of transfer layer bailey frame platform of high-rise building

Abstract

The invention relates to a construction method of a transfer layer bailey frame platform of a high-rise building and belongs to the technical field of building construction. The construction method mainly comprises the steps that lattice columns are mounted; bailey frames are erected; I-shaped beams are hoisted; crossbeam formwork bottoms are built; sandwich plates are built; and transfer layers are constructed. Compared with the prior art, under the premise that the quality can be guaranteed, the construction method has the multiple remarkable advantages of convenient implementation, safety and reliability.

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 a 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. [0003] According to the search, the Chinese invention patent with the application number of 201010135856.1 discloses a construction method for the transfer floor of a high-rise building beam structure. , easy quality control, low cost, and convenient construction. However, in fact, because the transfer floor is full of scaffolding and the supporting formwork is made of wooden keels, it not only requires a lot of labor and materials, but also has the following problems: 1) It needs to be installed on the ground floor and the first floor (-2, -1, 1) It is diffic...

However, in fact, because the transfer floor is full of scaffolding and the supporting formwork is made of wooden keels, it not only requires a lot of labor and materials, but also has the following problems: 1) It needs to be installed on the ground floor and the first floor (-2, -1, 1) It is difficult to ensure that the vertical poles of the support system on each floor are in the same position when erecting a three-story full hall support frame, and the force is not good; 2) The full hall support frame on the basement floor must be removed when the beam-slab concrete on the first floor reaches the design strength, thus affecting the conversion The construction period of the first floor; 3) It is only applicable to the conversion floor in the lower floor (such as the second floor)

Practice has shown that the above-mentioned prior art has the following disadvantages: 1) When there is no frame support structure, it is necessary to set up temporary supports to bear the Bailey beams, which is inconvenient for construction; more difficult

In particular, the bottom mold of the concrete structure in the suspension system is supported on the load-bearing platform, which not only has high requirements on the quality of the rebar suspender, but is also easily affected by the construction load, because the quality of the suspender directly affects the "load bearing" of the suspension of the flat rebar suspender. The stability of the "platform", and the suspender structure has very limited ability to withstand the horizontal impact generated during the construction process and pouring concrete, so it is difficult to maintain stability, which not only affects the construction quality, but also has certain safety hazards
