Classification of network structure

There are many kinds of net structure, which can be classified according to different standards.

First, according to the structure of the network frame itself can be divided into: single-layer network frame structure, two-layer network frame structure; Three layer network frame. Among them, single-layer and three-layer network frames are suitable for the cases with a small span (no more than 30m) and a particularly large span (more than 100m), respectively, and have few engineering applications in China.

Second, according to the construction materials are divided into: steel mesh frame, aluminum mesh frame, wood mesh frame, plastic mesh frame, reinforced concrete mesh frame and composite mesh frame (such as the combination of steel mesh frame and reinforced concrete slab), among which steel mesh frame has been widely used in China, and composite mesh frame can also be used as floor layer structure.

Three, according to the supporting situation can be divided into: peripheral support, four-point support, multi-point support, three-side support, side support and mixed support form.

Four, according to the different composition, can be divided into four categories:

1, cross truss system network frame;

2. Triangular cone system network frame;

3. Four-angle cone system network frame;

4, hexagonal cone system network frame.

The fourth classification method is a popular one in China.
