Stress control of grid structure

2.1 protective configuration of grid structure

"Code for design of steel structures" and "code for seismic design of buildings" play an extremely important and important role in guiding and restricting the design of grid structures in modern grid projects. In the practical process of organizing and carrying out the protection and configuration of grid structures, the above documents should be strictly followed, and the roof structure of grid projects should be assisted by the shape of grid structures The vertical horizontal support structure and transverse horizontal support structure are added to form the space truss support structure system with closed characteristics.

It is necessary to reasonably carry out the design work of support parameters, and standardize the estimation of wind strength of supporting structure between columns at the end and horizontal support structure of roof to bear the wind strength of mountain wall. It is necessary to control and ensure that the rigid frame column and inclined beam structure have good lateral stability by using rigid tie bar components, and at the same time, the use of corner brace structure should be avoided. For the purlin part of the grid structure, it is necessary to avoid the purlin from acting as the tie bar component at the same time, and the section steel material should be selected to prepare and configure the tie bar component, and the section steel material should be selected to construct and equip in the support structure part of the grid structure, and the round steel material should be avoided to be used for the construction and configuration.

2.2 stress control of grid structure

In the process of carrying out the stress control of grid structure in grid engineering project, the relevant technical disposal work should be carried out according to the difference between welded ball grid structure and spiral ball grid structure.

For the welded ball grid structure, the stress intensity control of the grid structure should give full play to its own technical advantages, such as high mechanical strength, good hardness and tight structure.

For the spiral sphere grid structure, the stress strength control of the grid structure should fully solve the weak problems in the aspects of compressive capacity and shear capacity, use high-strength bolt components to connect the basic nodes between the grid structures, and carry out the optimization and disposal of relevant technical components.

2.3 pay attention to the construction management of grid structure

To organize and carry out the grid structure construction of the grid project, all the technical personnel participating in the construction activities shall be supervised, and the relevant construction work shall be organized and carried out in strict accordance with the design scheme of the grid structure of the grid structure project. All the steel reinforcement materials to be used shall be determined in advance before the construction, which can have good quality and technical performance, so as to avoid the application of materials due to construction The unreasonable selection of materials has a bad impact on the actual quality state obtained in the construction process of part of the grid structure. In the actual construction process, reasonable construction quality management and supervision work should be carried out to ensure the best effect of relevant construction activities.

    Focusing on the topic of structure construction technology in grid structure engineering, this paper selects the important significance of grid structure design work and the basic application points of structure construction technology in grid structure engineering, and carries out a brief explanation and analysis from two specific aspects, aiming to provide effective and solid experience for researchers in related fields and construction personnel of grid engineering Test support conditions. It is of great significance for improving and optimizing the overall quality of grid structure design and construction in China to do a good job in the rational use of grid structure in the process of design and construction.
