Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a corbel support structure in a beam-column connection node. Background Art

[0002] The connection node between concrete columns and beams is one of the key issues in the design of concrete buildings. The effectiveness of the connection node directly affects the stiffness, stability and bearing capacity of the overall structure, and also affects the difficulty and progress of on-site construction. At present, when precast beams are connected to concrete columns, it is necessary to build a temporary support structure below the installation position of the precast beam to support the precast beam. After the precast beam is supported by the support structure, the construction personnel fix the end of the precast beam to the concrete column through the node connection structure. After the node connection is constructed, the temporarily built corbel support structure needs to be removed. However, during the use of the corbel support structure currently used for beam-column connection, generally, the tension screw members are pre-embedded on the precast beam first, and then the support structure is installed on the tension screw members respectively. This method requires the staff to screw multiple bolts when installing or separating the support structure from the tension screw members, and the operation is relatively cumbersome. Therefore, we propose a corbel support structure in the beam-column connection node to solve the above problems. Utility Model Content

The tops are fixedly connected to the corresponding L-shaped plates 7, respectively, which can play an auxiliary supporting role for the L-shaped plates 7, so as to enhance the bending resistance of the L-shaped plates 7. When using this corbel support structure, the four embedded pipe fittings 3 can be first embedded and cast inside the prefabricated column. When the support structure needs to be installed, the four threaded connecting pipes 4 fixed on one side of the first support seat 1 can be respectively inserted into the corresponding embedded pipe fittings 3, and then one end of the four threaded connecting rods 5 on one side of the second support seat 2 can be respectively inserted into the corresponding threaded connecting pipes 4, and the transmission assembly 6 is operated to rotate, thereby driving the four threaded connecting rods 5 to rotate at the same time. Finally, the rotated threaded connecting rods 5 will be respectively connected and fixed to the corresponding threaded connecting pipes 4. At this time, the installation operation of the support structure is completed. When the support structure needs to be removed later, it is only necessary to rotate the transmission assembly 6 in the opposite direction.

The hand wheel 606 is provided to facilitate the rotation operation of the rotating shaft 601, and the anti-skid patterns provided on the surface can increase the friction between the hand and the surface of the hand wheel 606, thereby achieving an anti-skid effect.

After the rotating shaft 601 rotates, it will drive the two driving gears 604 to rotate. With the cooperation of the four driven gears 605, it can realize the simultaneous rotation of the four threaded connecting rods 5.
