Explain in detail the whole process of space frame aerial closing

 


1. After the grid structure is installed at high altitude, the distance between the grid and the support should be adjusted. For this reason, several groups of chain jacks should be installed above the grid for horizontal adjustment.

2. Check the overall elevation of the grid to prevent uneven height. The elevation and horizontal distance should become one end firstly, and the steel tube should be inserted for connection. Tighten the inverted chain on one side and loosen the inverted chain on the other side so that the distance gradually becomes appropriate.

3. After the adjusted bar on one side is fixed gradually, relax the inverted chain on the other side and continue to fine-tune the elevation of the grid on the other side. The fixed side of the grid should also be observed while adjusting to prevent open welding。

4. After adjusting the elevation of the grid frame in the other side , tighten the distance with inverted chain, check the positioning condition preliminarily, insert the plug rod and fix it with spot welding after it is basically correct. Note that the spot welding plug rod should have a certain slope to ensure the center of the space frame is slightly higher than the support.

5. Check all dimensions of the space frame after the closing points of the bars around the space frame are fixed, and weld them in accordance with the welding procedure.

Shape of steel space frame structure

图片
  The steel space frame  structure can realize various spatial regular shapes such as arches, circles, spherical shells, and saddle shapes, as well as various irregular shapes. Moreover, if the same shape and different structures are compared, the cost of the steel space frame  structure is relatively low. The shape of the steel space frame  structure refers to the regular or irregular changes in the three-dimensional shape of the grid. Due to the special structure of the space frame structure and the high-precision factory manufacturing requirements, the more precise components required for the complex space frame  shape can be processed in the factory. Through the subtle changes in the angle of the screw holes of the bolt ball joints and the changes in the length of the rods, the space frame  structure can be fitted to the complex shape requirements of the architectural modeling.  At present, the space frame structure has almost become "all-match", and all kinds of spatial

  Steel space frame  structure is widely used in various buildings, such as   stadiums, exhibition halls, high-speed railway station buildings, terminal buildings, large factories, etc.; steel space frame  structure is a large-span steel structure as the main structure; it has poles The parts have the advantages of reasonable force, light weight, good integrity and stability, large space rigidity, good seismic performance, beautiful appearance, and low cost. What are the main types of steel space frame  structures? The first type is composed of triangular pyramid units, and has three forms: triangular pyramid space frame , evacuated triangular pyramid space frame  and honeycomb triangular pyramid space frame . The second type is composed of a plane truss system, which has four forms: two-way orthogonal diagonally placed space frame , two-way orthogonally placed space frame , two-way diagonally diagonally placed space frame  and three-way space frame . The third type is composed of qua

Space frame dome structure

图片
The space frame  dome uses a spherica l dome  as the main structural system, and the outside of the space frame is covered with plates or glass according to different needs. The glass dome can meet the lighting needs of the building. Natural light is filtered into the environment through the glass interface, making the building visually light and transparent. The space frame  dome uses a bolted ball space structure  as the main structure, and the covering material can be divided into blocks according to the size of the modular. Compared with the hyperboloid molding material, the cost is lower.
