Technical Field
[0001] The utility model relates to the technical field of column and joist connection structures, in particular to a support column and joist connection structure. Background Art
[0002] In the foundation pit supporting structure, the column is an important supporting structure that bears the ground load and protects the foundation pit. It is divided into three types: top supporting columns, inner branch columns and surrounding supporting columns. The concrete simply supported beams, continuous beams and frame beams that support masonry walls and floor (roof) covers are called supporting beams. Supporting beams are used in conjunction with columns to enhance the bearing capacity of the building.
[0003] When connecting and installing common columns and joists on the market, it is usually necessary to insert bolts into the holes reserved for the columns and joists and fix them by tightening the bolts. The connection is subject to large stress concentration, which is prone to cracks and deformation, affecting the overall bearing effect after the connection. Therefore, a support column and joist connection structure is proposed to address the above problems. Utility Model Content
[0004] The utility model aims to provide a connecting structure of a supporting column and a joist beam, so as to solve the problem that cracks and deformations are easily generated when bolts are inserted into the column and the joist beam for fastening.

By setting a connection structure that is easy to disassemble for the column body 1 and the joist body 2, compared with the rigid connection of the column and the joist using bolts in the prior art, the connection is not easy to produce cracks and deformation, and is not easy to affect the overall bearing effect after the connection.
[0023] The first clamping block 4 fits tightly with one of the depressions of the column body 1, and the hard spring 5 is arranged between the first clamping block 4 and the inner wall of the first groove 3 opened in the beam body 2, which is convenient for the insertion of the first clamping block 4 and the preliminary fixation of the beam body 2; a reinforcing rod 7 is provided in the moving part 6, and the first clamping block 4 is provided at both ends of the beam body 2 to increase the overall strength of the moving part 6; the fixing bolt 12 is threadedly connected with the fixing block 11, and the fixing block 11 fits tightly with the column body 1, which is convenient for the movement of the second clamping block 13 and the further fixation of the bracket 9; the positioning block 16 is inserted into the middle depression of the limit block 15 and fits tightly with the bracket 9, and one end of the long bolt 17 passes through one side of the limit block 15 until it is inserted into the positioning block 16, which is convenient for the further fixation of the beam body 2.
[0024] Working process: When installing and connecting the column body 1 and the joist body 2, first place the column body 1 in a suitable position, then install the bracket 9 at a suitable position of the column body 1, the user holds the bracket 9, inserts the positioning plate 8 set on one side into one of the recesses of the column body 1, and then rotates the fixing bolt 12 in the tightening direction until the second clamping block 13 and the second groove 14 opened in the column body 1 fit tightly, effectively fixing the bracket 9, and then holds the moving piece 6 to move it toward the middle direction of the joist body 2. Since the moving piece 6 and the first clamping block 4 are fixedly connected, the first clamping block 4 is driven to move in the same direction.
