Description

Technical Field

[0001] The utility model relates to the field of strengthening and fixing structures, in particular to a node strengthening structure for a steel structure beam. Background Technique

[0002] A steel structure beam generally consists of a cross beam and a vertical beam, and the connection nodes thereof are generally fixed by welding. In order to improve the fixing stability, a strengthening structure is generally used to strengthen the connection nodes between the cross beam and the vertical beam.

[0003] At present, the Chinese utility model with the publication number CN218597825U discloses a strengthening structure for a steel structure, which relates to the technical field of steel structures and includes: a first steel beam; a second steel beam; a pair of strengthening frames symmetrically connected between the first steel beam and the second steel beam; a connection seat connected to the bottom of the first steel beam, and the connection seat is installed on a building steel structure; a pair of fixing components respectively connected between the connection seat and the corresponding strengthening frame. This application has the effects of simple structure and convenient installation, and can greatly improve the strengthening effect of the steel structure, making the building use more reliable and safe.

[0004] To sum up, although this strengthening structure can achieve the purpose of fixing, there are still certain problems in use. For example, the size of the fixing plate that supports the cross beam of this strengthening structure is fixed and can only be applicable to the cross beam width that matches it. However, the widths of the steel structure cross beams on the market are different at present. Therefore, its applicability is poor. At the same time, the fixing method of this strengthening structure with the cross beam and the vertical beam adopts the method of screwing bolts. This method requires drilling holes in the cross beam and the vertical beam in advance. When drilling holes, it is not only easy to damage the structures of the cross beam and the vertical beam, but also the labor intensity of the staff is relatively heavy, and the installation is relatively troublesome. Content of the Utility Model

[0005] The purpose of the utility model is to provide a node strengthening structure for a steel structure beam, and its advantages are strong applicability and convenient installation.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a node strengthening structure for a steel structure beam includes a first strengthening plate and a second strengthening plate. The number of both the first strengthening plate and the second strengthening plate is two. L-shaped support blocks are bolted to both the first strengthening plate and the second strengthening plate. A first connection block is bolted to the bottom of the L-shaped support block. A bidirectional threaded rod is threadedly connected between the two first connection blocks. Second connection blocks are bolted to both the two first strengthening plates and the two second strengthening plates. A first tension screw rod is threadedly connected between the two second connection blocks. Third connection blocks are bolted to both the first strengthening plate and the second strengthening plate. A second tension screw rod is threadedly connected between the two third connection blocks.

[0007] With the above technical solution, in the utility model, L-shaped support blocks are installed on both of the two first reinforcement plates and the two second reinforcement plates. When the bidirectional threaded rod between the two first connection blocks is rotated, the distance between the two first reinforcement plates and the distance between the two second reinforcement plates can be adjusted, so as to adjust the distance between the two L-shaped support blocks fixed to the cross beam, making it applicable to cross beams of different widths for fixation, improving its applicability. By installing second connection blocks on both of the two first reinforcement plates and the two second reinforcement plates, when the first tensioning screw rod is rotated, the two first reinforcement plates and the two second reinforcement plates can be tensioned, making the first reinforcement plates and the second reinforcement plates closely attached to the surface of the vertical beam. Through the action of the third connection block and the second tensioning screw rod, the first reinforcement plates and the second reinforcement plates can be tensioned, making the L-shaped support blocks and the strengthening blocks closely attached to the outer wall of the vertical beam, achieving the overall installation without drilling holes, improving the installation speed and reducing the installation difficulty.

[0008] The utility model is further configured as: wear-resistant pads are bonded to the opposite sides of the two L-shaped support blocks.

[0009] With the above technical solution, the friction between the L-shaped support block and the cross beam is increased and mutual wear is prevented.

[0010] The utility model is further configured as: a first rotating block is fixedly sleeved at one end of the bidirectional threaded rod.

[0011] With the above technical solution, it is convenient to rotate the bidirectional threaded rod.

[0012] The utility model is further configured as: a limiting guide rod is symmetrically and slidably connected between the two L-shaped support blocks.

[0013] With the above technical solution, the movement of the two L-shaped support blocks is limited.

[0014] The utility model is further configured as: a second rotating block is fixedly sleeved at one end of the second tensioning screw rod.

[0015] With the above technical solution, it is convenient to rotate the second tensioning screw rod.

[0016] The utility model is further configured as: limiting insertion rods that are symmetrically bolted to the second reinforcement plate and slidably connected to the first reinforcement plate are provided.

[0017] With the above technical solution, the first reinforcement plate and the second reinforcement plate are limited.

[0018] The utility model is further configured as: strengthening blocks that are bolted to the first reinforcement plate and the second reinforcement plate and bolted to the L-shaped support blocks are provided.

[0019] By adopting the above technical solution, the stability of the fixation between the first reinforcement plate and the second reinforcement plate and the L-shaped support block is improved.

[0020] The present utility model is further configured such that: micro-convex teeth are integrally reinforced on both the first reinforcement plate and the second reinforcement plate.

[0021] By adopting the above technical solution, the stability of the fixation between the first reinforcement plate and the second reinforcement plate and the vertical beam is improved, and the depth of the micro-convex teeth inserted into the surface of the vertical beam is limited, and the internal structure of the vertical beam will not be damaged.

[0022] In summary, the present utility model has the following beneficial effects:

[0023] 1. In the present utility model, L-shaped support blocks are installed on both of the two first reinforcement plates and the two second reinforcement plates. When the bidirectional threaded rod between the two first connection blocks is rotated, the distance between the two first reinforcement plates and the distance between the two second reinforcement plates can be adjusted, so as to adjust the distance between the two L-shaped support blocks fixed to the cross beam, making it applicable to cross beams of different widths for fixation and improving its applicability;

[0024] 2. In the present utility model, second connection blocks are installed on both of the two first reinforcement plates and the two second reinforcement plates. When the first tensioning screw rod is rotated, the two first reinforcement plates and the two second reinforcement plates can be tensioned, so that the first reinforcement plates and the second reinforcement plates are closely attached to the surface of the vertical beam. Through the action of the third connection block and the second tensioning screw rod, the first reinforcement plates and the second reinforcement plates can be tensioned, so that the L-shaped support blocks and the strengthening blocks are closely attached to the outer wall of the vertical beam, achieving the overall installation without drilling holes, improving the installation speed and reducing the installation difficulty.
