Description
Technical Field
The utility model relates to the technical field of building structures, in particular to a truss intersecting reinforcement joint.
Background
In the pipe truss structure, pipe nodes are important components of the pipe truss structure, and the size, shape, position and orientation of each node converging member are different, so that the geometric characteristics and stress performance of the nodes are very complex, and therefore, the pipe nodes become the key in the steel pipe structure design. In engineering design, designers often only notice checking the strength and stability of the rod, and neglect the design calculation of the bearing capacity of the node, and in most cases, the damage of the steel pipe node occurs before the rod fails.
The current common pipe truss reinforcing node method comprises node plate reinforcement, stiffening rib reinforcement, inner partition plate reinforcement and outer sleeve reinforcement. These several reinforcement modes have the disadvantages: the node plates and stiffening rib reinforcing modes have relatively large external influence; the main pipe must be disconnected for the reinforcement of the inner partition plate; the outer sleeve reinforcing mode has little influence on the appearance and does not need to break a main pipe, but engineers can assume that the outer sleeve and the main pipe are stressed simultaneously when calculating the joint strength after reinforcing the sleeve, the actual condition is that the outer sleeve transmits force through an end welding line and a longitudinal welding line, the force cannot be applied simultaneously only by the four welding lines, stress concentration can be generated at the welding line, and particularly when the joint range is longer, the stress concentration of the welding line is more obvious, so that certain potential safety hazard exists.
