Description

Technical Field

[0001] The utility model relates to the technical field of steel beam reinforcement, in particular to a thin-wall reinforcement structure of an I-shaped steel seat. Background Art

[0002] I-beam steel seat is a commonly used structural support element, which plays a vital role in engineering. The I-beam steel seat includes a web and flanges installed at both ends of the web. The web provides the main bearing capacity and support force, while the flanges increase the overall stability and rigidity, so that the I-beam steel seat can effectively support beams or other structural members, ensuring that they can safely and stably bear the load. The web is the main thin-walled position of the I-beam steel seat. By using the design of the reinforced structure, the stress concentration phenomenon of the I-beam steel seat during use can be reduced, its service life can be extended, and the maintenance cost can be reduced;

[0003] For example, a steel beam reinforcement structure disclosed in the authorization announcement number CN220469240U includes a reinforcement block arranged between an I-shaped horizontal steel beam and a longitudinal steel beam, one end of the longitudinal steel beam is connected to one side of the horizontal steel beam through the reinforcement block, the reinforcement block is embedded in a steel groove on one side of the horizontal steel beam, the top and bottom ends of the reinforcement block are fixedly connected with horizontal clamping blocks, the two horizontal clamping blocks are respectively fitted on the top wall and the bottom wall of the horizontal steel beam, and two longitudinal clamping blocks are fixedly connected on the side wall of the reinforcement block away from the horizontal steel beam, the two longitudinal clamping blocks are respectively embedded in the steel grooves at the ends of the longitudinal steel beam, by welding the horizontal clamping blocks at the top and bottom of the reinforcement blocks, and welding the longitudinal clamping blocks on one side of the reinforcement blocks, A fixing hole is opened on the block, and the bolt is set in the fixing hole. Furthermore, a limiting groove is opened in the middle of the fixing hole. In the process of fixing the steel beam, the bolt is limited in the limiting groove through the cooperation of the limiting groove and the limiting plate, and the workers are no longer required to carry the bolts to work at the same time. However, this technical solution mainly utilizes E-shaped reinforcement blocks to connect and support the web and wing plates of the I-beam, and the force range of the reinforcement blocks is relatively narrow. When the I-beam is subjected to external loads, the reinforcement blocks can only be limited to a smaller area to bear the pressure, and the overall force distribution is not uniform enough, which may cause stress concentration in some areas of the thin wall of the web, thereby increasing the stress of the material.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , the utility model provides an embodiment: a thin-wall reinforcement structure of an I-beam steel seat, including an I-beam steel seat body 1, the I-beam steel seat body 1 includes a web and wing plates integrally formed at the upper and lower ends of the web, a C-beam 4 is installed on the outer wall of one side of the web, the top and bottom ends of the C-beam 4 are integrally formed with an upper connecting plate 5, and a slot 8 for plugging with the wing plate is provided below the upper connecting plate 5. Through the design of the upper connecting plate 5 and the slot 8, a stable connection structure is formed between the C-beam 4 and the wing plate of the I-beam steel seat body 1.

Both ends of the surface of the upper connecting plate 5 are installed with spring positioning pins 6 for connecting the upper connecting plate 5 and the wing plate;

[0023] The double triangular arm reinforcement beam 3 is used to connect the head and tail ends of the C-shaped beam 4.

[0025] The staff can take out another reinforcement structure again, and the C-beam 4 and the back of the back plate 2 in the reinforcement structure are no longer installed with the external threaded convex pin 10 and the external threaded convex pin 2 11. Then, when the reinforcement structure is connected to the I-beam seat body 1, the external threaded convex pin 10 and the external threaded convex pin 2 11 in the previously assembled reinforcement structure will play the role of connecting the two reinforcement structures and the I-beam seat body 1.

At this time, the double triangular arm reinforcement beam 3 and the C-beam 4 form an integral component, so as to further reduce the stress on the I-beam, thereby increasing the overall bearing capacity of the structure.

[0030] When the embodiment of the present application is used, the staff first takes out the reinforcement combination, so that the C-beam 4 is installed, slidably, and plugged into one side of the web of the I-beam seat body 1. At this time, the C-beam 4 is located between the upper and lower wing plates on the same side of the I-beam seat body 1, and the C-beam 4 and the outer wall of the web of the I-beam seat body 1 are tightly attached to each other, and the wing plate of the I-beam seat body 1 is connected to the slot 8. When the I-beam seat body 1 and the C-beam 4 are assembled in place, the pin end of the spring positioning pin 6 automatically enters the positioning hole 9 and the I-beam seat In the wing plate of the main body 1, the connection and assembly operation of the reinforcement structure and the I-beam seat main body 1 is completed.
