Embodiment
[0022] The basement roof of this embodiment adopts two-way slabs, and the construction elevator model is SCD200 / 200 double-cage construction elevator. The structure after construction is as follows figure 1 shown. The specific installation method is as follows:
[0023] A basement roof unsupported elevator installation method, it comprises the following steps:
[0024] a) Calculation of bearing capacity: Convert the local concentrated force acting on the two-way slab by the construction elevator into an equivalent uniformly distributed live load value, and calculate the design value of the uniformly distributed load on the basement roof 1, so that the uniformly distributed load on the basement roof 1 The design value is greater than the equivalent uniform live load value;
[0025] b) Fabrication of the construction elevator foundation: Based on the fact that the design value of the uniformly distributed load on the basement roof 1 is greater than the equivalent uniformly dis...

The invention discloses a basement roof support-free elevator installation method. By means of the method, the mounting efficiency is high, and the construction cost is low. The method comprises the steps that a, the bearing capacity is calculated, wherein local concentrated force applied to a two-way slab by a construction elevator is converted into an equivalent uniform distribution live load value, an application uniform distribution load design value of a basement roof is calculated, and the application uniform distribution load design value of the basement roof is made to be larger than the equivalent uniform distribution live load value; b, a foundation of the construction elevator is manufactured, wherein foundation bolts are mounted on the basement roof through a chemical bar-planting method, an angle iron frame base plate is mounted, and then the foundation of the construction elevator is formed; c, the construction elevator is mounted, wherein a standard knot bearing frame is mounted on the foundation of the construction elevator, and attachment bars, an elevator cage, an electrical transmission system, an anti-falling and limiting device and protective guardrails are mounted on the standard knot bearing frame respectively. By means of the method, a load transmission supporting system is omitted, and construction is easy and convenient.
Description
technical field [0001] The invention relates to the technical field of construction elevator installation, in particular to a method for installing an unsupported elevator on a basement roof. Background technique [0002] In the construction of high-rise buildings, when the construction elevator is installed on the basement roof, a load transfer support system must be set up to transfer the operating load of the construction elevator to the basement floor according to the floor. When setting up the load transfer support system, the fastener type steel pipe frame is generally used to transfer the load, or the concrete column is used to carry the transfer load, and the load of the construction elevator is transferred to the basement floor. Especially in the construction of multi-storey basement structures, especially the 4-5 storey basement structure is equipped with a load support transfer system, which is set up layer by layer, using more materials, requiring a lot of labor ...
