Steel Structure Grid

Introduction

Steel frame grid construction is a type of building structure that uses steel and grid components as the main structure creating a structure that is lightweight, high-strength, durable, and economical. In modern architecture, steel frame grid construction is widely used in large-scale, long buildings. This article will introduce the steel frame grid construction project from aspects such as design, structure, and construction.

Design

  1. Selection of steel grid structure

 The selection of the steel frame grid structure mainly depends on the span, load, and usage requirements of the building. Generally, steel frame grid structures divided into conical grid structures, spherical grid structures, and hyperbolic grid structures. Among these, spherical grid structures are suitable for large-span buildings such as halls and stadiums, while conical grid structures and hyperbolic grid structures are suitable for lightweight workshops, squares, and open-air parking modules.

  1. Selection of steel

Steel frame grids should use high-strength alloy steel or ordinary carbon structural steel, with strength and elastic modulus that meet design requirements. Additionally, factors such the ductility and corrosion resistance of the steel need to be considered. In actual projects, Q345B steel is generally used as the main structural.

  1. Foundation design

The foundation design of steel frame grid buildings should be determined based on factors such as the bearing capacity of the land, the load of building, and the terrain and weather conditions. It is generally divided into deep foundations and shallow foundations. Deep foundations include pile foundations and foundation pit excavation, while shallow mainly include spread foundations, strip foundations, and reinforced concrete foundations.

Structure

1. Steel Structure Grid Nodes

Steel structure grid nodes are one of the most critical parts of steel structure grid systems requiring high strength, reliability, precise construction, and ease of installation. Steel structure grid nodes are divided into hollow nodes and solid nodes, with hollow nodes being more.

2. Steel Structure Grid Trusses

The main part of a steel structure grid system is composed of multiple steel structure trusses. These trusses typically consist diagonal support rods, main beams, and transverse support rods. Their load-bearing capacity and strength must be matched according to design requirements.

3. Steel Structure Grid

Steel structure grid panels are the covering parts of the steel structure grid system. They are required to be lightweight, soundproof, insulating, and durable., sandwich panels or metal roof panels are used as panel materials.

Construction Process

The construction of steel frame grid structures can be divided into two stages: manufacturing and installation. manufacturing stage includes factory production and on-site processing, with a focus on prefabrication accuracy and quality. The installation stage includes erecting columns, installing beams, installing panels.

Safety Measures

Strict safety measures must be implemented during the construction of steel frame grid structures, such as strictly enforcing safety management systems, complete safety protection facilities, strictly following safety operation procedures, and quality testing of steel materials and accessories.

Conclusion

Steel frame grid structure engineering has advantages such lightweight, high strength, convenient installation, economical use, and low maintenance costs, making it suitable for large-span buildings and special structures. The structural design must be, the construction process rigorous, and safety measures complete to ensure the safety, quality, and successful completion of the project.
