AI Technical Summary
In existing technologies, the connection between steel roof trusses and concrete columns requires a large number of large-diameter anchor bolts, which leads to an uneconomical increase in the cross-section of the concrete column and inconvenience in construction. Furthermore, the anchor bolt positions are prone to conflict with the reinforcing bars.
Pre-embedded parts are used to define shear grooves on the top of the concrete corbel. The support base plate is embedded in the groove and connected to the pre-embedded parts through connectors. The blocks are used to resist horizontal forces, reducing the number and diameter of anchor bolts and improving shear resistance.
Simplify the construction process, reduce the number of anchor bolts, improve shear resistance, reduce construction costs, avoid conflicts between anchor bolts and reinforcing bars, and enhance connection stability.
