Problems solved by technology

[0003] In the reinforced concrete irregular slab-column shear wall, there are irregular opening layouts in each floor slab, and the steel staircase is erected in the hollow of the irregular opening of the slab-column shear wall structure. 1. In this way, the steel staircase spans the hollow, and the length and direction of the steel staircases on each floor are different and vertically staggered. In this way, it is necessary to arch the connection position between the steel staircase and the floor to improve the bearing capacity; in addition, multiple lifting points for the steel staircase hoisting should also be set In the irregular plane of each floor of the slab-column shear wall structure, it is required that the lifting point has the least impact on the structure, so the irregular slab-column shear wall structure cannot simply adopt the requirements of the code and conventional experience for construction

Embodiment Construction

[0092] Such as Figure 1 to Figure 6 A hoisting construction method for a steel staircase in a non-regular slab-column shear wall structure is shown, and the method includes the following steps:

[0093] Step 1. Establishment of the finite element model of the irregular slab-column shear wall structure:

[0094] Step 101, according to the architectural and structural design drawings, use the computer to use the finite element analysis software to establish the i-th floor irregular slab-column shear wall structure model; wherein, the i-th floor in the i-th layer irregular slab-column shear wall structure model Open the i-th polygonal opening on ;

[0095] Step 102, step 101 is repeated for one time to establish an irregular slab-column shear wall structure model; wherein, i is a positive integer, and 1≤i≤I, and I is a positive integer greater than 5;

[0096] Step 2. Overall analysis of the finite element model of the irregular slab-column shear wall structure:

[0097] Use ...

Abstract

The invention discloses a hoisting construction method for a steel staircase in an irregular slab-column shear wall structure. The method comprises the following steps: 1. Establishment of a finite element model of the irregular slab-column shear wall structure; 2. Non-regular slab The overall analysis of the finite element model of the column shear wall structure; 3. Acquisition of the arching area of ​​the installation position of the steel staircase; 4. Acquisition of the column position of the lifting point of the steel staircase; 5. The installation of the main lifting point structure; 6. The installation of the steel staircase Lifting; 7. Installation of steel stairs. The method of the invention has simple steps and reasonable design, and through the analysis of the finite element model of the irregular slab-column shear wall, it provides a basis for the hoisting construction of the steel staircase at the irregular opening of the irregular slab-column shear wall, and improves the connecting position of the steel staircase and the floor stability, and reduce the impact on the irregular slab-column shear wall during the hoisting process.

Description

technical field [0001] The invention belongs to the technical field of construction of steel stairs in irregular slab-column shear walls, and in particular relates to a hoisting construction method for steel stairs in irregular slab-column shear wall structures. Background technique [0002] With the development of social economy and the improvement of people's aesthetic needs, the layout and structure of buildings are becoming more and more complex and changeable, and the structure is developing from regular plane and straight space to irregular space, beautiful shape and high headroom. [0003] In the reinforced concrete irregular slab-column shear wall, there are irregular opening layouts in the floors of each floor, and the steel stairs are erected in the hollow of the irregular openings of the slab-column shear wall structure. 1. In this way, the steel staircase spans the hollow, and the length and direction of the steel staircases on each floor are different and vertic...
