Introduce the characteristics of steel grid

We all know that equilateral triangle is the most stable physical principle, so we can see that many buildings in daily life are built with the principle of equilateral triangle, especially the popular steel grid structure, which is thoroughly applied.Triangular cone steel grid, its basic control module is composed of three string bar, three oblique bar composed of triangular cone, namely tetrahedron. The triangular cone can be in order, it can be confused.

The bending stiffness of the three-way spherical lattice is larger than that of the two-way spherical lattice, so it is suitable for the large-span structure. The planar design of the three-way spherical lattice can be used in the triangular shape, the ladder shape and the regular hexagonal shape, and it can also be used in the circular planar design. Steel grid checkerboard quadrate cone spherical grid: Rotate all oblique quadrate cone spherical grid by 45° horizontally, so that the spherical grid comes to the vertical surface of the building axis, and the lower chord reaches a 45° Angle with the building axis, and the steel grid is obtained.

The cone top is located below the center of the square. The four ventral rods are connected to the top of the cone by the square quadrate node. The four pyramidal bars are connected to each other as periodically as possible to become the four pyramidal steel grid.

The length of the spherical grid support column is less than that of the lower string rod under tension, so the support frame is more reasonable. The amount of concrete works at the junction of each node is less, so the amount of steel is less.

The above is the characteristics of various types of steel truss. In fact, the building will choose which kind of structure to build according to the situation.
