Description

Technical Field

[0001] The invention relates to the technical field of column raising on beams, and in particular to a column raising structure on beams and a method thereof. Background Art

[0002] In underground buildings, due to the different functions of the floors, the upper and lower parts of the floors usually adopt different structural types, such as frame structure, shear wall structure, etc. In order to achieve load transfer between different structural types, it is necessary to set up a transfer layer on the appropriate floor. Underground structural column conversion is one of the common conversion forms, which realizes load transfer by setting beam columns on the conversion beam.

[0003] In the existing column-on-beam structure, since the thickness of the conversion beam is generally about 1 meter, the column-on-beam structure can provide stable support. However, the thickness of the conversion beam of some buildings will be greater than this value during design. At this time, the increase in the thickness of the conversion beam will cause its internal stress distribution to be more complicated. In particular, when the increased thickness fails to obtain reasonable structural design optimization, local stress concentration is likely to occur, thereby reducing the overall structural strength. When the heavy conversion beam is under load, if its cross-sectional shape, size or connection method is improperly designed, its stability may be reduced and it may be unable to effectively support the superstructure.

[0029] In this embodiment, if Figures 1 to 6As shown, a connection component is used to realize the fixed connection of the casting formwork. The connection component is connected to the steel column 4. The connection component includes a connection frame 5. The connection frame 5 includes a connection part 501 that is clamped in the grooves on both sides of the "I"-shaped connection beam 401. The connection part 501 is fixedly connected to the outside with a docking column 502. The docking column 502 is internally slidably connected with an extension rod. A spring is fixedly connected between the extension rod and one side of the inner cavity of the docking column 502. One end of the extension rod is fixedly connected to a No. 1 installation frame 503. The No. 1 installation frame 503 is provided with a guide rail 504 on the side facing the connection beam 401. The outside of the guide rail 504 is symmetrically slidably connected to two guide blocks 505. The two guide blocks 505 are rotatably connected to a reinforcement on the side facing the connection part 501. The connecting rod 506, the other ends of the two reinforcing connecting rods 506 are rotatably connected to the top and bottom of the docking column 502 respectively, the top and bottom of the two No. 1 mounting frames 503 are slidably connected with an "L"-shaped extension frame 507, and the four extension frames 507 form a square frame, and the outer parts of the other two sides of the square frame are sleeved with No. 2 mounting frames 508, and the two No. 2 mounting frames 508 are fixedly connected with a connecting cylinder column 509 on the side facing the connecting beam 401, and the connecting cylinder column 509 is provided with a transmission cavity inside the side facing the connecting beam 401, and the transmission cavity is slidably connected with a transmission rod, and the two transmission rods are fixedly connected to the top and bottom of the connecting beam 401 respectively, and the other end of the transmission rod is fixedly connected to the top of the transmission cavity through a spring, and the connecting part 501 The shape is triangular, and the interiors of the No. 1 installation frame 503, the No. 2 installation frame 508 and the extension frame 507 are all provided with installation holes for assembly with the casting template. First, the connection part 501 of the connection frame 5 is embedded in the grooves on both sides of the "I"-shaped connecting beam 401 to achieve preliminary positioning. The triangular design of the connection part 501 helps to increase the stability and force-bearing area of ​​the connection. The extension rod inside the docking column 502 can be telescopically adjusted according to actual conditions under the action of the spring to adapt to casting templates of different thicknesses. When the extension rod is extended, the guide rail 504 and the guide block 505 on the No. 1 installation frame 503 drive the strengthening connecting rod 506 to rotate, thereby further enhancing the connection strength between the connection assembly and the casting template.

The first installation frame 503, the second installation frame 508 and the extension frame 507 are all provided with installation holes to facilitate assembly with the casting template. Through these installation holes, the casting template can be firmly fixed to the connection component.Forming an integral structure, the connection assembly significantly enhances the connection strength between the casting template and the steel column 4 through multiple connections and support structures, and improves the stability of the overall structure. The telescopic adjustment mechanism of the extension rod enables the connection assembly to adapt to casting templates of different thicknesses, improving the flexibility and adaptability of the design. The adjustment mechanism of the transmission rod and the spring effectively absorbs and disperses the impact of external loads on the structure, improving the seismic performance of the structure. The modular design makes the installation and disassembly process of the connection assembly more convenient and quick, reducing the construction difficulty and cost; In this embodiment, if Figures 1 to 7As shown, a strengthening component is used to improve the strength of the steel beam 1. The strengthening component is connected to the steel beam 1. The strengthening component includes a support beam 2 fixedly connected to both sides of the steel beam 1. The support beam 2 includes four side plates 201 fixedly connected to both sides of the steel beam 1. A "Z"-shaped strengthening frame 202 is fixedly connected between the two side plates 201 on the same side of the steel beam 1. Connecting plates 203 are fixedly connected between both ends of the strengthening frame 202 and the side plates 201. An "X"-shaped connecting frame 204 is fixedly connected to the opposite surfaces of the side plates 201 on both sides of the steel beam 1. The four side plates 201 are fixedly connected on both sides of the steel beam 1. A diagonal bracing beam 3 is provided, and a connecting plate 301 is fixedly connected between the diagonal bracing beam 3 and the side plate 201 on one side. A diagonal bracing frame 302 is fixedly connected to the opposite surfaces of the diagonal bracing beams 3 on both sides of the steel beam 1. The diagonal bracing frame 302 is in the shape of a triangular component formed by splicing two pointed ends. Two triangular diagonal bracing grooves 303 are provided inside the diagonal bracing frame 302. The bottom of the diagonal bracing beam 3 and the bottom of the supporting beam 2 are in the same plane. A connecting piece 6 is provided between the bottom of the opposite surface of the diagonal bracing beam 3 and the supporting beam 2. A second mounting plate 602 with an acute angle is fixedly connected to the bottom of the diagonal bracing beam 3 on one side relative to the supporting beam 2. A right-angled No. 1 mounting plate 601 is fixedly connected to one surface of the bottom of the support beam 2 relative to the diagonal support beam 3, and a connecting square column 603 is fixedly connected to the opposite surface of the No. 1 mounting plate 601 and the No. 2 mounting plate 602, and a guide cavity is opened inside the connecting square column 603, and a guide rod 604 is fixedly connected to the inside of the guide cavity, and a sliding member 605 is slidably connected to the outside of the guide rod 604, and springs are fixedly connected between the two ends of the sliding member 605 and the two ends of the inner cavity of the guide cavity, and the two springs are both sleeved on the outside of the guide rod 604, and two springs are rotatably connected to the two sides of the sliding member 605. The No. 2 support link 607 and the No. 1 support link 606, the other ends of the two No. 1 support links 606 are both rotatably connected to the side of the No. 2 mounting plate 602 facing the No. 1 mounting plate 601, the other ends of the two No. 2 support links 607 are both rotatably connected to the side of the No. 1 mounting plate 601 facing the No. 2 mounting plate 602. First, the four side panels 201 are fixedly connected to both sides of the steel beam 1 to form the basic frame of the support beam 2, and then, a "Z"-shaped reinforcement frame 202 is installed between the two side panels 201 on each side, and it is firmly connected to the side panel 201 through the connecting plate 203.This design increases the lateral and longitudinal stiffness of the support beam 2. At the same time, an "X"-shaped connecting frame 204 is installed on the opposite surfaces of the side plates 201 on both sides of the steel beam 1, which further enhances the overall stability and torsional resistance of the support beam 2. Four diagonal bracing beams 3 are fixedly connected to both sides of the steel beam 1, and together with the support beam 2, they constitute a stable support system. The diagonal bracing beams 3 and the bottom of the opposite surfaces of the support beams 2 are connected by a connecting piece 6, which enhances the synergy between the two. The diagonal bracing frame 302 (a triangular component with two pointed ends spliced ​​together) installed on the diagonal bracing beam 3 cooperates with the connecting plate 301 through its internal diagonal bracing groove 303 to provide additional support and stability. When external loads act on the structure, the sliding piece 605 in the connecting square column 603 between the No. 1 mounting plate 601 and the No. 2 mounting plate 602 will slide along the guide rod 604, and the sliding of the sliding piece 605 is restrained by the springs at both ends. The restriction and adjustment of the second support link 607 and the first support link 606 can automatically adjust their angles according to the stress conditions, thereby dispersing and balancing the load. This dynamic adjustment mechanism helps to maintain the stability of the structure and reduce stress concentration. Through the synergistic effect of the support beam 2, the reinforcement frame 202, the connecting frame 204, the diagonal brace beam 3 and the diagonal brace frame 302, the strength and bearing capacity of the steel beam 1 are significantly enhanced. The design of the "Z"-shaped reinforcement frame 202 and the "X"-shaped connecting frame 204 improves the overall stability of the support beam 2, while the diagonal brace beam 3 and the diagonal brace frame 302 further enhance the structure's anti-lateral displacement and anti-torsion capabilities. The dynamic adjustment mechanism of the connector 6 enables the reinforcement component to automatically adjust the support state under different load conditions to maintain the stability and safety of the structure. The modular design makes the installation and disassembly process of the reinforcement component more convenient and quick, reducing the construction difficulty and cost. At the same time, it is also convenient for later maintenance and overhaul work. The reinforcement component improves the seismic performance of the structure by enhancing the overall rigidity and stability of the structure, and reduces the risk of damage in natural disasters such as earthquakes.
