Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and specifically relates to a reinforcement device for steel structure connection nodes. Background Technology

[0002] Steel structure buildings are a type of building that uses steel as the main structural material. They are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. These components are connected by welds, bolts or rivets to form a stable overall structure. Steel structure buildings have the characteristics of high strength, light weight, fast construction speed and good seismic performance.

[0003] Currently, steel structure connection nodes are usually connected only through web plates and high-strength bolts. However, this connection method results in excessive stress concentration, which greatly reduces the connection strength at the steel structure connection node, affects the service life of the steel structure connection node, is not conducive to the normal use of the steel structure connection node, and reduces the bending performance of the steel structure beam. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcement device for steel structure connection nodes, so as to solve the problem that the stress concentration at existing steel structure connection nodes is too high, which leads to a significant reduction in the connection strength at the steel structure connection nodes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforcement device for a steel structure connection node, comprising: a steel column, one side of which is connected to a first connecting beam, one end of which is connected to a second connecting beam, and one side of the first and second connecting beams are connected to a web plate; a reinforcement component, which is disposed on the top of the first and second connecting beams, the reinforcement component including a fixing plate, the fixing plate being connected to the top of the first connecting beam, and both sides of the fixing plate having threaded rods, the threaded rods being threadedly connected to the fixing plate, and one end of the threaded rods being connected to a connecting block, one end of the connecting block being connected to an annular plate, one side of the annular plate having an opening, and the inner walls of the opening being connected to two rods, the rods passing through the connecting block, the top of the second connecting beam being connected to a limiting block, the limiting block being arranged in a U-shape; and a shielding component, which is disposed on the top of the first connecting beam.

[0006] Preferably, the shielding assembly includes connecting plates, two connecting plates are connected to the top of the first connecting beam, and two baffles are connected between the two connecting plates. Both baffles are provided with through slots, and the top of one of the connecting plates is rotatably connected to a top plate via a hinge.

[0007] Preferably, one end of the screw is connected to a torsion plate, and the surface of the torsion plate is provided with raised patterns.

[0008] Preferably, a rubber pad is provided on one side of the inner wall of the limiting block.

[0009] Preferably, an elastic rope is connected to one side of the top plate, and a limit rod is connected to one side of one of the connecting plates.

[0010] Preferably, a tie rod is connected to the top of the top plate.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] (1) This utility model sets up a reinforcing component and screws the screw so that the screw drives the annular plate to move to one side of the limiting block through the connecting block. Then, the annular plate is rotated so that the annular plate is fitted on the limiting block. Then, the screw is screwed again so that the screw drives the annular plate to move to one side of the inner wall of the limiting block so that the annular plate is stuck on the limiting block. This can disperse the stress at the steel structure node, realize the reinforcement of the steel structure connection node, greatly improve the connection strength at the steel structure connection node, reduce the service life of the steel structure connection node, facilitate the normal use of the steel structure connection node, and improve the bending performance of the steel beam.

[0013] (2) By setting up a shielding component, when it is necessary to shield and protect the screw at the top of the first connecting beam, the top plate is rotated so that the top plate rotates on the connecting plate through the hinge. The top plate then closes the top of the two connecting plates through two baffles, thereby shielding and protecting the screw at the top of the first connecting beam. This prevents the screw from rusting due to prolonged dampness during the rainy season, which is detrimental to the normal use of the screw and helps to effectively protect the screw.

[0020] Reference Figures 1-4 As shown, this utility model provides the following technical solution: a reinforcement device for a steel structure connection node, comprising: a steel column 1, a first connecting beam 2 connected to one side of the steel column 1, a second connecting beam 3 connected to one end of the first connecting beam 2, and a web plate 4 connected to one side of the first connecting beam 2 and the second connecting beam 3; a reinforcement component, the reinforcement component being disposed on the top of the first connecting beam 2 and the second connecting beam 3, the reinforcement component including a fixing plate 5, the fixing plate 5 being connected to the top of the first connecting beam 2, and screw rods 6 penetrating through both sides of the fixing plate 5, the screw rods 6 being threadedly connected to the fixing plate 5, and a connecting block 7 being connected to one end of the screw rods 6, an annular plate 8 being connected to one end of the connecting block 7, an opening 9 being opened on one side of the annular plate 8, and a rod 10 being connected between the two sides of the inner wall of the opening 9, the rod 10 penetrating through the connecting block 7, a limiting block 11 being connected to the top of the second connecting beam 3, the limiting block 11 being arranged in a U-shape; and a shielding component, the shielding component being disposed on the top of the first connecting beam 2.

[0021] Through the above technical solution:

[0022] Specifically, when it is necessary to reinforce the steel structure connection node, screw 6 is turned so that screw 6 drives the annular plate 8 to move to one side of the limiting block 11 through the connecting block 7. Then, the annular plate 8 is rotated so that the annular plate 8 rotates on the connecting block 7 through the rod 10, so that the annular plate 8 is fitted onto the limiting block 11. Then, screw 6 is turned again so that screw 6 drives the annular plate 8 to move to one side of the inner wall of the limiting block 11, so that the annular plate 8 is stuck on the limiting block 11. In this way, the stress at the steel structure node can be dispersed, thereby reinforcing the steel structure connection node.

[0023] Further embodiments are provided in this utility model, see below. Figures 1-3 The shielding assembly includes a connecting plate 16. Two connecting plates 16 are connected to the top of the first connecting beam 2, and two baffles 14 are connected between the two connecting plates 16. Both baffles 14 have through slots 15. The top of one of the connecting plates 16 is rotatably connected to a top plate 17 via a hinge.

[0024] Through the above technical solution:

[0025] Specifically, when it is necessary to shield and protect the screw 6 at the top of the first connecting beam 2, the top plate 17 is rotated so that the top plate 17 rotates on the connecting plate 7 through the hinge, so that the top plate 17 closes the top of the two connecting plates 16 through the two baffles 14, thereby shielding and protecting the screw 6 at the top of the first connecting beam 2.

[0026] Reference Figures 1-4 One end of the screw 6 is connected to a torsion plate 12, the surface of the torsion plate 12 is provided with a raised texture 13, a rubber pad 21 is provided on one side of the inner wall of the limiting block 11, an elastic rope 19 is connected to one side of the top plate 17, a limiting rod 20 is connected to one side of one of the connecting plates 16, and a pull rod 18 is connected to the top of the top plate 17.

By setting rubber pads 21, the limiting block 11 and the annular plate 8 are protected. By setting elastic rope 19 and limiting rod 20, it is easy to pull the elastic rope 19 to hang on the limiting rod 20, so that the top plate 17 can be limited on the two connecting plates 16. By setting pull rod 18, it is easy to pull the top plate 17.
