Problems solved by technology

[0003] However, in the super high-rise environment, the installation of steel structures also faces many challenges. Generally, the conflict between the narrow component stacking site and the large number of components, the conflict between the low performance of the tower crane and the heavy components, and the conflict between high-altitude operations and the harsh environment Factors such as these always affect the steel structure installation and the overall progress of the project. In addition to the influence of the above factors, the construction of steel trusses on special-shaped structures on super high-rise roofs also has small roof construction work areas, difficult positioning of special-shaped structures, and high difficulty in precise positioning. , Heavy-duty structure hoisting, high risk and other difficulties

Embodiment Construction

[0052] The present invention will be further described below in conjunction with specific examples.

[0053] see figure 1 , a kind of super high-rise special-shaped structure steel structure truss construction method of the present invention, comprises the following steps:

[0054] First, establish a three-dimensional simulation model of the truss;

[0055] Step 1: Using the preset node coordinate list, input it into AutoCAD to establish the point coordinates of the overall model. According to the side view and front view, connect the nodes into a line model;

[0056] Step 2: According to the preset bar section diagram combined with the bar section dimension table, using the line model, each connection line is used as the positioning control axis of the bar, and the preliminary three-dimensional model is generated by using drawing commands such as 3D sweeping, stretching, and lofting;

[0057] Step 3: The three-dimensional model simply generated by using the line model is i...

Abstract

The invention discloses a construction method for a steel structure truss of a super high-rise special structure; the construction method comprises the following steps of: establishing a three-dimensional simulation model of the truss; deepening the design of a truss steel structure; making each member of the truss; pre-assembling the members on the ground; and integrally assembling the truss at a high level. As the construction method for the steel structure truss of the super high-rise special structure, disclosed by the invention, is adopted, the construction method for the steel structure truss of the super high-rise special structure, which successfully solves difficulties of small roof construction face, difficult positioning of the special structure, large accurate locating difficulty, high hoisting danger of a heavy structure and so on, is achieved; and the construction method for the steel structure truss of the super high-rise special structure, disclosed by the invention, has the advantages of strong reliability of construction quality, high production rate, fast construction progress and strong economic and social benefits.

Description

technical field [0001] The invention relates to a truss construction method, in particular to a super high-rise special-shaped structure steel structure truss construction method. Background technique [0002] At present, domestic super high-rise buildings are in the ascendant. Steel structures are widely used in super high-rise buildings due to their advantages of high strength, high rigidity, short construction period and strong earthquake resistance. Various steel structure construction technologies are also booming. development trend. [0003] However, in the super high-rise environment, the installation of steel structures also faces many challenges. Generally, the conflict between the narrow component stacking site and the large number of components, the conflict between the low performance of the tower crane and the heavy components, and the conflict between high-altitude operations and the harsh environment Factors such as these always affect the steel structure ins...
