How to distinguish between truss and grid?

1, with different properties: Truss is a structure with hinged members at both ends. Grid is a spatial structure composed of multiple components connected by nodes in a certain grid form.

2. Different basic units: the basic units that make up the grid are triangular cones, triangular cubes, cubes, truncated quadrangles and so on. Truss is a plane or spatial structure composed of straight bars, generally with triangular elements. Truss members mainly bear axial tension or pressure.

3. The design requirements are different: the truss should have components that meet the requirements and good connectors, including rivets, pins and welds. The bar section of grid structure should be calculated and determined according to the strength and stability.

Precautions:

1. In order to avoid error accumulation, the primary and secondary trusses are assembled as a whole, and the iron platform made of 16 channel steel is used as the assembly platform. In order to ensure the straightness accuracy of the truss, the chords should be leveled strictly with a level, and the outer ends of the upper and lower chords should be tightened with thin steel wires for straightening the chords.

2. Measure the positioning sideline of the web member at the node position in the chord, and install the web member according to the sideline position. After the chord is adjusted, some web members are installed at the end, middle and joint positions immediately to fix the shape of the truss and avoid deformation when installing other web members.

3. In order to improve the construction efficiency, avoid secondary reverse transportation and block the traveling route of the crane, the truss is assembled near the installation projection position, and the assembly platforms are arranged on both sides of the channel parallel to the channel direction.
