Embodiment Construction

[0068]The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0069]Such asFigure 1-Figure 3As shown, the large-scale equipment installation and main structure reverse calculation and construction method of the present invention:

[0070]1. Formwork support system check calculation

[0071]1) Calculation of the axial force of the upright rod on the hollow I-beam

[0072]a. Calculation of design value of uniform load on panel

[0073]According to the "Uniform Standard for Reliability Design of Building Structures" GB50068-2018 and the following formula (1-1), the design value of the panel uniform load is calculated.

[0074]q=[γG(G2K×h+G3k×h+G1k)+γQ×Q1k]×b (1-1)

[0075]Among them, q—design value of uniformly distributed load on panel (kN)

[0076]γG—The partial coefficient of permanent load, which is taken as 1.3;

[0077]γQ-Variable load sub-factor, taking 1.5;

[0078]G2k—The weight of the newly poured concrete (kN / m3), which is 24kN / m3;

[0079]G1...

Abstract

The invention relates to a calculating and constructing method for installation of large equipment and reverse operation of a main structure, and belongs to the technical field of architectural designand cross construction. The method comprises the following main steps: 1. checking a formwork supporting system; 2. lifting the large equipment; and 3. setting up a rolled steel joist conversion platform and a formwork bracket. A scientific calculating and constructing method is provided for the installation of the large equipment and the reverse operation of the main structure, the problems thatthe large equipment is difficult to install after the completion of the main body in a traditional construction method, and labor and time are wasted are solved, the construction procedure is simple,the construction efficiency is high, and the method conforms to the national energy conservation and environmental protection construction policy.

Description

Technical field[0001]The invention relates to a calculation and construction method for the installation of large equipment and the main structure of the reverse construction, belonging to the technical field of architectural design and construction.Background technique[0002]With the rapid development of my country's economy, large-scale industrial plants have emerged in large numbers. The traditional large-scale equipment installation and construction process is: the main structure is completed → the equipment is moved to the foundation of the track → the moving track is laid → the large equipment is placed on the moving track by a large crane → the hydraulic jack is started to make the large equipment move slowly and horizontally →Large equipment is installed in place. The installation cost of this large-scale equipment installation method is high, which seriously affects the construction period.Summary of the invention[0003]Based on the above shortcomings in the prior art, the te...
