Quality control elements of steel space frame structure

With the acceleration of the social modernization process, the steel space frame structure building has been extensively developed in the construction industry by virtue of its unique advantages, playing an irreplaceable role. SAFS steel structure will give you a talk about the quality control elements of the steel space frame structure.

The project quality of space frame is prone to problems mainly as follows:

When the flange plate and the thickened or widened connecting plate are butt welded, the transition of the inclination should be made according to the requirements;

The connection surface of the end plate is rough, the cutting is not flat, or the control is improperly welded with the beam column flange plate, which causes the end plate to be warped and deformed, causing the contact surface between the end plates to be inconsistent, and the connecting bolts are not strong.Therefore, the structural properties such as bending, tension, and shear resistance of the node cannot be satisfied;

When the steel space frame beams and columns are spliced, the splicing joints of the flange plate and the web are placed on the same section, causing hidden engineering hazards. When splicing joints, the joints of the flange plate and the web plate must be staggered according to the regulations;

The column foot is also prone to some problems in the process of manufacturing and installation, for example, the distance between the embedded anchor bolt and the short concrete column is too close. In the process of hoisting the steel space frame, the concrete at the top of the column will be broken or collapsed due to some lateral force;

In the process of installation, the reservation of the shear groove and the setting of the shear key are often forgotten, which may easily lead to the damage of the anchor bolts.At the same time, pay attention to the accuracy of the position of the anchor bolts. If the bottom plate is punched, the opening of the bottom plate of the column foot should not be too large, which will easily make the column foot unstable;

In the process of manufacturing and installing the steel space frame, attention should be paid to quality issues, otherwise it will affect the quality of the final building, affect the safety of the building, and bury hidden dangers for the owner's safety.
