A steel column and steel beam connection node reinforcement device

Abstract

This utility model discloses a steel column-beam connection node reinforcement device, belonging to the technical field of reinforcement devices. It includes a steel column body, with connecting angle steel bolted to the outer side of the steel column body, and a steel beam body bolted to the outer side of the connecting angle steel. By providing a reinforcement mechanism, the stiffness and local bearing capacity of the core area of ​​the node, such as the column flange and beam end, are increased. This more effectively transfers the bending moment and shear force at the beam end to the steel column body, preventing premature buckling or tearing of the column flange or web in stress concentration areas. It also restricts beam end rotation and displacement, achieving the purpose of stable reinforcement. By providing a limiting mechanism, the connection reinforcement between the support limiting plate and the reinforcement metal sleeve is easily completed, dispersing stress. Simultaneously, the support limiting plate undertakes part of the displacement restriction function, reducing the burden on the core bolts, reinforcement angle steel, and connecting angle steel, ensuring the stability of the steel column-beam connection node.

[0023] like Figures 1-3 As shown, the reinforcement mechanism 4 includes a reinforcing angle steel 41. Multiple high-strength bolts 42 are fitted onto the outer side of the reinforcing angle steel 41. These bolts 42 are threadedly connected to the steel beam body 3 and the steel column body 1, respectively.

A mounting washer 44 is movably sleeved on the outer side of the high-strength limiting threaded post 43. A first anti-loosening nut 45 is threaded onto the outer side of the high-strength limiting threaded post 43. Reinforcing metal sleeves 46 are fixed to both sides of the two reinforcing angle steels 41. A positioning metal sleeve 47 is fixed to the outside of the reinforcing metal sleeve 46. One side of the reinforcing angle steel 41 is attached to the main body of the steel column 1, and another side of the reinforcing angle steel 41 is attached to the main body of the steel beam 3. The corresponding surface of the mounting shim 44 is tightly attached to the positioning metal sleeve 47. The reinforcing angle steel 41 is fixedly connected to the main body of the steel column 1 by high-strength bolts 42, and the reinforcing angle steel 41 is fixedly connected to the main body of the steel beam 3 by high-strength bolts 42. A groove is provided inside the positioning metal sleeve 47, and the size of the groove is adapted to the size of the high-strength limiting threaded column 43.

[0024] like Figures 1-2 and Figure 4As shown, the limiting mechanism 5 includes a supporting limiting plate 51, an installation groove 52 is provided on the outer side of the supporting limiting plate 51, a first semi-threaded post 53 is fixed on the outer side of the supporting limiting plate 51, a second semi-threaded post 54 is installed on the outer side of the reinforcing metal sleeve 46, a connecting washer 55 is movably sleeved on the outer side of the second semi-threaded post 54 and the first semi-threaded post 53, a second anti-loosening nut 56 is threadedly connected to the outer side of the first semi-threaded post 53 and the second semi-threaded post 54, the supporting limiting plate 51 and the steel column body 1 are welded and fixed, the corresponding surface of the supporting limiting plate 51 is in contact with the reinforcing metal sleeve 46, the radius of the first semi-threaded post 53 is equal to the radius of the second semi-threaded post 54, and an anti-slip groove is provided on the outer side of the second anti-loosening nut 56.

[0025] The working principle of this utility model is as follows: All parts used in this device are made of structural steel. A reinforcing mechanism 4 is provided. When the steel column body 1 and the steel beam body 3 are connected and fixed, the flange of the steel beam body 3 is bevel-welded to the steel column body 1, and connecting angle steel 2 is fixedly connected to the steel column body 1 and the steel beam body 3 using bolts. After the connection is completed, reinforcing angle steel 41 is installed on the top and bottom of the steel beam body 3, so that the reinforcing angle steel 41 fits against the corresponding surface of the steel column body 1. Then, high-strength bolts 42 are used to fix the reinforcing angle steel 41 to the steel column. After the reinforcing angle steel 41 is installed on the outside of the main body 1 and the main steel beam 3, the reinforcing metal sleeve 46 is movably fitted onto the outside of the two reinforcing angle steels 41, and the positioning metal sleeve 47 is movably fitted onto the outside of the high-strength limiting threaded post 43. Then, the mounting washer 44 is movably fitted onto the outside of the high-strength limiting threaded post 43. Finally, the first anti-loosening nut 45 is threadedly connected to the high-strength limiting threaded post 43, so that the corresponding surface of the first anti-loosening nut 45 is pressed against the outside of the high-strength limiting threaded post 43. This directly increases the strength of the core area of ​​the node, such as the column flange and the beam end. The increased stiffness and local bearing capacity can more effectively transfer the bending moment and shear force at the beam end to the main body of the steel column 1, preventing premature buckling or tearing of the column flange or web in stress concentration areas. It can also limit the rotation and displacement of the beam end, achieving the purpose of stabilization and reinforcement. By setting a limiting mechanism 5, after the reinforcing angle steel 41 and the reinforcing metal sleeve 46 are fixed, the supporting limiting plate 51 is welded to the outside of the main body of the steel column 1. The corresponding surface of the first semi-threaded column 53 on the outside of the supporting limiting plate 51 is in contact with the second semi-threaded column 54, and the corresponding surface of the supporting limiting plate 51 is also in contact with the reinforcing... The outer side of the metal sleeve 46 is fitted, and the connecting gasket 55 is movably sleeved on the outer side of the second half-threaded post 54 and the first half-threaded post 53. Then, the second anti-loosening nut 56 is threadedly connected to the first half-threaded post 53 and the second half-threaded post 54, which conveniently completes the connection and reinforcement between the support limiting plate 51 and the reinforcing metal sleeve 46. This can disperse stress and reduce stress concentration. At the same time, the support limiting plate 51 undertakes part of the function of limiting displacement, reducing the burden on the core bolt, the reinforcing angle steel 41, and the connecting angle steel 2, and ensuring the stability of the steel column and steel beam connection node.
