UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a beam column quick connecting node structure to solve the problem that the connecting node is not convenient for centering clamping and fixed connecting node, is not conducive to adapting to different inner diameters of vertical hollow round steel columns and quickly inserting and connecting the steel beam, which affects the convenience of beam column quick connection.

The bearing block provides support for the clamping arm, so that the three sets of clamping arms can rotate outward and contact the inner wall of the vertical hollow steel column, thereby fixing the connecting seat to the top of the vertical hollow steel column. When the inner diameter of the vertical hollow steel columns to be connected is different, it is only necessary to adjust the moving distance of the push arm to drive the clamping arm to rotate to adapt to the vertical hollow steel columns with different inner diameters. This realizes convenient centering, clamping and fixing of the connection node, and facilitates the adaptation to vertical hollow steel columns with different inner diameters.

[0016] By moving the steel beam, the A-type insertion frame moves, allowing the insertion post to be inserted into the A-type insertion frame. The insertion post presses against two sets of A-type claws, causing them to rotate around the support column, thus inserting the insertion post into the two sets of A-type claws. Under the elastic action of the torsion spring, the torsion spring causes the two sets of A-type claws to close, fixing the insertion post inside the A-type claws. Further pressing of the insertion post causes the insertion post to contract, rotating the B-type claw. The B-type claw rotates around the linkage shaft, causing the two sets of B-type claws to rotate to the end face position of the insertion post. Under the elastic action of the spring, the spring causes the insertion post to reset, locking the B-type claws at the end face position of the insertion post. This prevents the insertion post from shifting inside the B-type insertion frame, increasing the connection strength between the A-type and B-type insertion frames, thus completing the rapid installation connection of the beam and column. This facilitates the rapid insertion and installation connection of steel beams and improves the convenience of rapid beam-column connection. Attached Figure Description
