Engineering Characteristics

Features of stadium space frame:

1.Public buildings with extremely high safety requirements.

2.Unique shape, less support is required during use, so it is difficult to design and install.

3.Anti-seismic, anti-wind and snow.

4.High durability requirements and frequent maintenance are required to avoid affecting the safety of use.

Application Area

1.School stadium space frame stand

2.Space frame of the stadium stands of the City Sports Center

3.Space frame structure of stadium stands

4.Space frame of football stadium stands

5.Space frame of the grandstand of the track and field stadium

6.Space frame of skating stadium stands

7.Space frame of the swimming pool stand

8.Space frame of diving hall grandstand


The stadium stand space frame is generally a cantilever structure, which is based on the commander’s stand and seats. For large stadiums, the stadium stand space frame closes the surroundings to form a magnificent stadium appearance.

1.The BJMB structure is statically indeterminate for many times, the internal force will be automatically distributed and adjusted automatically, multi-dimensional force, high safety, more suitable for stadiums.

2.The shape is simple, but there are few pillars and many overhangs, which will lead to high cost of the stadium.

3.Strong anti-earthquake, anti-wind and snow (strengthen when calculation is needed), and can be used as a refuge in disasters.

4.Surface anti-corrosion must be done well, otherwise it will be difficult to maintain and increase use cost.

Process Description

1.Design process:

The space frame structure used in the gymnasium should be calculated for internal forces and displacements under external loads, and should be carried out according to the specific conditions of the internal forces and displacements under the action of earthquakes, temperature changes, support settlements and construction and installation loads. Calculation.

2.Production process:

(1) The welding of the sealing plate or the cone and the steel pipe is the key to the processing of the space frame rod. The specification requires the weld level to be level two. Although most space frame processing plants are equipped with automatic welding machines, the welding gun Angle, speed, swing position and speed all need to be controlled manually, which will affect the welding quality of grid frame members. Therefore, the space frame processing plant needs a mature, tested and effective rod welding process.

(2) Bolt ball processing belongs to finishing. The key to the quality of the bolt ball is the accuracy of the final angle of the screw hole; the key to the quality of the bolt ball, and the accuracy of the fixture is the key to the angle accuracy.

(3) The verticality of the component and the quality of the weld are the key to the processing of the support.

3.Installation process:

The construction plan must be multiple sets of spares, multiple sets of combined use, the most dangerous factor in the installation process is structural instability. It is recommended that large stadiums be installed by LF skilled workers. Most of the on-site installations are bolted (according to the structure type and calculation results).
