The first priority of space frame structure construction is safety, and the second is the reasonable and effective control of the construction quality under the premise of ensuring the quality, Let’s make a look at how to effectively control:
Prepare for construction and review the construction drawing of space frame. Drawing are the basis for the construction of the project. The person who in charge should organize the staff to be familiar with the specifications and technical condition related to the project drawing and the project,and understand the design intent.
Carefully review the design of the space frame installation and construction team. The design of the construction team is a technical document that the construction unit comprehensively guides the implementation of the project, The completeness of the design of the construction team directly affects the quality and progress of the project. Therefore, the design review of the construction team must the targeted and focused.
Strengthen the quality of on-site construction, and do a good job in quality control of space frame foundation projects. The foundation of space frame engineering generally adopts concrete independent column foundation. The construction of foundation concrete, steel bars, and formwork are the same as other engineering procedures and methods. The embedded bolts in the foundation independent column are the focus of quality control. The deviation of the spacing and height of the bolts directly affects the installation quality of the space frame project. During the construction process, we require the construction unit to strictly control it.
The control of the main project of the space frame and the installation of steel components. When installing columns and beams, mainly check whether the shim under the column bottom plate is solid and level, whether the column is vertical and displaced, the beam is vertical, straight, laterally bent, bolt tightening degree, and friction surface cleaning. After acceptance, , Can be lifted. When the grid is installed to form a space fixed unit, and the acceptance is passed, the construction unit is required to compact the space between the column bottom plate and the top surface of the foundation with expanded concrete.
Control of ball installation. Bolt connection on space frame construction generally uses high-strength bolts and ordinary bolts. Ordinary bolts connection,one end of each bolt cannot be filled with more than 2 gaskets. The bolt holes must not be reamed by gas cutting. After the bolts are tightened, the exposed threads must not be less than 2 pitches; Before using the high-strength bolts, we check the certificate and retest form of the bolts. During the installation process, the contact surface of the board stack should be flat, the contact surface should be greater than 75%, and the edge gap should be less than 0.8mm.
In the process of space frame structure engineering construction control,it is necessary to truly play the role of control. It is required to strictly control the progress during construction and engineers should also do a good job in quality inspection, so as to ensure the construction quality of space frame engineering.
