Construction technology of space frame processing

Below, the space frame processing company will introduce the construction technology of space frame processing

1. The measurement and setting-out work includes the review of the building axis and the inspection of the offset of the embedded parts. Especially in this project, the elevation is more complicated, and the inspection of the control elevation is particularly important.
2. There are many types of embedded parts in this project. The inside of the arch and on the arc beams in the east and west are flat embedded parts, and under the arch are embedded bolts. The elevations are different everywhere. Before installing the steel structure, it needs to be carefully reviewed. If there is any deviation, it must be dealt with.
3. The selection and optimization of the support system is one of the key research topics in construction. When selecting the support system, comprehensive factors such as safety, stability, operability, and economy should be considered. For the connection problem of structural installation work, this process is compiled in accordance with the scheme of bowl-button scaffolding. The supporting system adopts fastener-type scaffolding, prepares the corresponding erection plan, and builds the grid elevation control point into a tic-tac-toe frame according to the drawing, and the support point is set at the lower chord node.
4. The semi-finished products are transported to the site and should be hoisted to the work area after passing the flaw detection. All materials are sorted and stacked on the scaffold work platform, but concentrated loads are not allowed.
5. The rods and accessories should be installed according to the number according to the drawings, and installed from one side to the other according to the symmetry axis. The position of each point should be continuously checked during the installation process.
6. Once the installation deviation occurs, it should be adjusted immediately. The elevation can be adjusted up and down with a jack. The plane position should be supported by the jack at an angle of 75° left and right, and corrected to the drawing position until it is adjusted to the correct position.
7. After confirming that it is correct, proceed symmetrically on both sides for large-area installation. During the installation process, the rod size and bolt ball deviation must be strictly re-checked. The total size of every three rods should be reviewed, and the reference axis should be checked at any time.
