Description

Technical Field

[0001] The utility model relates to the field of steel structures, in particular to a connection structure of a steel structure column and a steel structure beam. Background Art

[0002] The connection structure between steel structure columns and steel structure beams is usually achieved by welding, bolting or riveting. These connection methods ensure the stability and bearing capacity between steel structure columns and beams to meet the overall stability and safety requirements of the building structure. Bolt connection uses bolts and nuts to fix the columns and beams together, which is convenient for disassembly and maintenance.

[0003] A Chinese patent with publication number CN220117442U discloses a connection structure between a steel structure column and a steel structure beam, including a steel column, a first steel beam, a support, a second steel beam and a connecting plate. The steel column is the main supporting and installing structure of the whole. The support is fitted inside the steel column. The first steel beam is connected to the outer surface of one end of the support. By setting the connection between the steel structure column and the steel structure beam in a split type, it is easy to disassemble and assemble, and convenient for subsequent maintenance and replacement. The connection between the steel structure column and the steel structure beam is fitted with each other, and a reinforcing rod is provided and inserted into the inside. Not only is the connection end high in strength, but the force is more uniform, thereby improving the strength of the steel structure and increasing the overall practicality.

[0004] During the connection process of the steel structure column and steel structure beam connection structure of the above patent, when using bolts for the final connection and fixing, the user is required to support and lift both sides of the bolt connection position to improve the effect of the bolt connection. Single independent installation is more difficult, which affects the installation efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a connection structure between a steel structure column and a steel structure beam. When the second connection block is inserted into the first installation cavity, the connection strip will be inserted into the first reserved cavity. After the slot is connected, the third connection column passes through the first through hole and the second through hole, which can avoid the need for the user to support and lift both sides of the bolt connection position, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a connection structure of a steel structure column and a steel structure beam, comprising a steel beam and a steel column for support, a first extension plate welded to one end of the steel beam, a second extension plate welded to the other end of the steel beam, a second connecting block welded to the middle position of the upper end of the first extension plate, four connecting strips are arranged around the lower end of the second extension plate, and a first installation cavity for connection and combination is arranged in the middle position of the four connecting strips.

[0007] Preferably, a first through hole is provided through the middle positions of the four connecting strips, four first reserved cavities are provided around the outside of the second connecting block, second through holes are provided at the lower ends of the four first reserved cavities, and the second through holes pass through the first extension plate and extend to the upper and lower ends.

[0008] Preferably, a recessed second reserved cavity is provided at the lower end inside the first extension plate, a temporary connecting plate for auxiliary connection is provided at the lower end outside the second reserved cavity, and a third connecting column for connection is provided at the temporary connecting plate facing the four second through holes inside the first extension plate.

[0009] Preferably, a rotatable transmission disc is provided at a middle position of the temporary connection plate, and a sliding block is provided on a side of the transmission disc facing the first extension plate.

[0010] Preferably, a second installation cavity is provided in the middle of the second reserved cavity toward the first reserved cavity, and the position of the second installation cavity recessed in the first reserved cavity overlaps with the position of the sliding block.

[0011] Preferably, a sliding rail is arranged around one side of the outside of the second installation cavity, and limiting rings for limiting are arranged on both sides of one end of the sliding rail facing the outside.

[0012] Preferably, the first through hole at the upper end of the second extension plate is fixedly connected to one end of the third connecting column by bolts.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model relates to a connection between two adjacent steel beams. First, a connecting strip is inserted into a first reserved cavity around a second connecting block. While being inserted, the second connecting block is inserted into the first installation cavity. Secondly, after being assembled, the temporary connecting plate drives the third connecting column to sequentially penetrate the second through hole in the first extension plate and the first through hole in the connecting strip. While driving the third connecting column to move, the sliding block is driven to be inserted into the second installation cavity, thereby restricting the temporary connecting plate. Finally, a bolt is embedded into the third connecting column through the first through hole, so that the bolt and the temporary connecting plate clamp and fix the connection position of the two adjacent steel beams, thereby improving the stability of the connection and the load-bearing capacity during subsequent use. The third connecting column replaces the bolts for subsequent connection to penetrate the connection position of the two adjacent steel beams in advance, thereby avoiding the generation of gaps between the two adjacent steel beams in the absence of bolt connection, resulting in poor bolt connection effect.

[0034] Working principle: When using the connecting structure to connect two adjacent steel beams 2, the second connecting block 9 at one end of one of the steel beams 2 is slidably placed in the first installation cavity 12 at the other end of the other steel beam 2. During the sliding combination process, the connecting strip 11 at the other end of the other steel beam 2 will be inserted into the first reserved cavity 10 around the second connecting block 9 at one end of one of the steel beams 2. After the combination, the temporary connecting plate 19 simultaneously drives the third connecting column 20 and the sliding block 23 to move toward the second reserved cavity 18. The temporary connecting plate 19 will be inserted into the second reserved cavity 18. While inserting, the third connecting column 20 will pass through the second through hole 14 and the first through hole 13 in turn, and the temporary connecting plate 19 will drive the connected connecting rod 22 and the sliding block 23 through the transmission disk 21 to be inserted into the second installation cavity 24.

During the sliding process, Restricted by the limiting ring 26, the bolts are embedded from the first through hole 13 and rotated to the inside of the third connecting column 20, thereby completing the connection between the two adjacent steel beams 2. When one end of the steel beam 2 provided with the second connecting block 9 is installed to the second mounting groove 27 inside the steel column 1, it slides horizontally and longitudinally, so that the gasket 15 is embedded in the second reserved cavity 18, and the second connecting column 16 is embedded in the second through hole 14. When one end of the steel beam 2 provided with the connecting strip 11 is installed to the first mounting groove 3 inside the steel column 1, it also slides horizontally and longitudinally, so that the first connecting block 5 is inserted into the first mounting cavity 12, and the first connecting column 6 passes through the first through hole 13 inside the connecting strip 11. After the two ends of the steel beam 2 are respectively embedded in the first mounting groove 3 and the second mounting groove 27, the filling plate 4 is fixed to the surface of the steel column 1 and to the upper end of the outside of the steel beam 2 by bolts, so as to wrap and protect the exposed first mounting groove 3 and the second mounting groove 27.
