Description

Cross-shaped section column steel frame beam column assembly type node with space inclined strut
Technical Field
The invention relates to the technical field of industrial production of cement, steel and the like and large-span building structures, in particular to a cross-shaped cross-section column steel frame beam column assembly type node with a space diagonal brace.
Background
In heavy industrial factory building and the long-span building structure, the requirement for the integral rigidity of the structure is difficult to guarantee only through the plane inclined strut, and the space constraint capacity of the space inclined strut to the structure is stronger, so that the structural integrity can be guaranteed more effectively. The insertion plate connecting joint is a joint type in which a branch pipe and a main pipe are bolted through an insertion plate and a joint plate. The plate joint has the advantages of free adjustment of joint size, simple connection, convenient construction and installation, shortened construction period, convenient processing and easy quality guarantee, and is widely applied to supporting connection.
Common types of board nodes are: the structure comprises I-type, T-type and single-groove type plug board connecting nodes, wherein the difference of the ultimate bearing capacity of different types of plug board connecting nodes is large, and the ultimate bearing capacity of the I-type plug board connecting nodes is the lowest and is only 1/3-1/2 of other two types of plug board connecting nodes; the T-shaped and single-groove type inserting plate connecting node reduces the lateral deformation of the inserting plate and effectively improves the rigidity of the node by arranging the stiffening rib at one side of the inserting plate, thereby delaying the buckling of a plate and improving the ultimate bearing capacity of the node; the resultant force of the gusset plates and the resultant force of the inserting plates in the single-groove type inserting plate joint have certain eccentricity, so that the eccentricity is generated, the axial center stress component of the branch pipe is easily changed into an eccentric stress component, and the instability mode of the branch pipe is changed when the branch pipe is pressed, so that the ultimate bearing capacity is reduced. The double-slot steel inserting plate joint solves the problem that the resultant force of the joint plate and the resultant force of the branch pipes are eccentric, and improves the rigidity and the bearing capacity of the inserting plate joint.
At present, for beam-column connection nodes, one common method is beam web bolt connection and beam flange welded connection bolt welding, and the other method is to weld a section of cantilever beam to a column flange and then connect the beam end and the cantilever beam through a bolt and a cover plate. The bolt welding connection has a field welding process on the flange, so that the welding quality and the assembling speed are difficult to guarantee, and the construction period is influenced to a certain extent. The bolted connection of cantilever beam end, the apron is too much, and the web all cuts at same cross-section with the edge of a wing, and this cross-section department stress is more concentrated, is in the weak position of whole root roof beam.
Based on the current situation, the invention provides a cross-shaped cross-section column steel frame beam column assembly type node with a space inclined strut.
