[0020] Reference Figure 1 and Figure 2 As shown, this utility model provides a steel structure beam reinforcement auxiliary device 100 (hereinafter referred to as beam reinforcement auxiliary device 100). The beam reinforcement auxiliary device 100 is applicable to both the reinforcement of existing steel beams and steel columns 600 and the reinforcement of newly added steel beams.

[0021] The beam reinforcement auxiliary device 100 includes a clamp structure 10 sleeved on the steel column 600 and a reinforcement structure 30 connected to at least one side of the clamp structure 10. The assembly and use of the beam reinforcement auxiliary device 100 with the steel column are described in accordance with the following reference. Figure 3 The steel beam is not shown.

The connecting component 13 is connected to the reinforcing structure 30. After installation, both the reinforcing structure 30 and the connecting component 13 are located inside the steel beam.

[0022] The beam reinforcement auxiliary device 100 of this utility model is applicable to steel structures. Specifically, it includes a clamping structure 10 sleeved on a steel column 600 and a reinforcement structure 30 connected to at least one side of the clamping structure 10. The clamping structure 10 includes a clamping member 11 and a connecting component 13 located on at least one side of the reinforcement structure. The connecting component 13 is connected to the reinforcement structure 30. After installation, both the reinforcement structure 30 and the connecting component 13 are located inside the steel beam, reducing the need for drilling on the steel beam, maintaining the structural strength of the beam and column. The steel structure beam reinforcement auxiliary device 100 has a lightweight and simple structure, convenient and simple installation steps, and low construction difficulty, greatly improving the construction efficiency and quality of the column, shortening the construction period, and effectively improving the reliability of beam-column joint installation.

[0023] Understandably, to address the reinforcement requirements of the steel column 600 and the steel beam, one reinforcement structure 30 is installed for reinforcement on one side, two reinforcement structures 30 are installed for reinforcement on both sides, and multiple reinforcement structures are installed for reinforcement on multiple sides. The reinforcement structures 30 and connecting components 13 are installed in a one-to-one correspondence. The exemplary diagram shows that double-sided reinforcement can be installed, that is, the clamp 11 is provided with two connecting components 13 on both sides to cooperate with the two reinforcement structures 30 for reinforcement operation.

[0024] Optionally, the connecting assembly 13 includes a first connecting plate 131 and a second connecting plate 133 spaced apart, with a mounting groove 13A formed between the first connecting plate 131 and the second connecting plate 133, and at least part of the reinforcing structure 30 is disposed in the mounting groove 13A and is detachably connected to the first connecting plate 131 and the second connecting plate 133.

[0025] Furthermore, the edge of the clamp 11 is welded and fixed to the steel column 600. The clamp 11 can be an annular square cylinder, with a clamp cavity 11A formed in the middle of the cylinder for fitting onto the steel column 600. Then, the first connecting plate 131, the second connecting plate 133 and the clamp 11 can be welded into a single structural component, or the clamp 11 can be formed by bending two sheet metal parts respectively. The two are arranged opposite each other and locked with bolts to form a clamp structure. The first connecting plate 131 and the second connecting plate 133 are respectively formed by bending the ends of sheet metal parts. At the same time, the middle of the sheet metal parts is bent to cooperate with another sheet metal part to form the clamp cavity 11A and the ends are enclosed to form the mounting groove 31A.

[0026] Furthermore, the first connecting plate 131 and the second connecting plate 133 are provided with fixing holes that communicate with the mounting groove 13A, and the insert plate 31 is provided with assembly holes 31A corresponding to the fixing holes. The first connecting plate 131 and the second connecting plate 133 are locked to the fixing holes and assembly holes 31A by bolts 40 so as to be detachably connected to the insert plate 31.

[0027] In this embodiment, the clamp 11, the first connecting plate 131, the second connecting plate 133, and the reinforcing structure 30 are all made of steel, and the bolts 40 are high-strength bolts 40, used to connect the connecting component 13 on the outside of the clamp 11 to the reinforcing structure 30, so that the reinforcing structure 30 and the clamp 11 are an integral unit to connect the steel beam and the steel column 600. Furthermore, the fixing holes on any connecting plate and the assembly holes 31A on the insert plate 31 are all provided in multiples. For example, the first connecting plate 131 and the second connecting plate 133 are each provided with 8 fixing holes, using a corresponding number of high-strength bolts 40 to increase the connection strength and connection stability between the connecting component 13 and the reinforcing component.

[0028] Optionally, the connecting assembly 13 further includes at least two ribs 135, which are respectively disposed on the surfaces of the first connecting plate 131 and the second connecting plate 133 on opposite sides. The ribs 135 are located between the two flanges 33, and the partial outer edge of the ribs 135 abuts against the inner surface of the steel beam.

[0029] In this embodiment, the rib 135 is also made of steel. The rib 135 is welded to the middle of the first connecting plate 131 and the second connecting plate 133, and the length extension direction of the rib 135 is the same as the length extension direction of the reinforcing structure. It serves to strengthen the structural strength of the connecting assembly 13. The outer edge of the rib 135 contacts the inner surface of the steel beam, improving the connection stability of the clamp 11 to the reinforcing structure via the connecting assembly 13. The number of ribs 135 is set as needed; an exemplary illustration shows one rib 135 on one connecting plate to strengthen the structural strength of the connecting assembly 13.

[0030] Furthermore, the insert plate 31 of the steel reinforcement structure 30 and the upper and lower wing plates 33 form an I-shaped structure.

[0031] Optionally, the mounting groove 13A is configured as a through groove with openings at both ends, and the reinforcing structure 30 includes an insert plate 31 and wing plates 33 vertically disposed on the upper and lower sides of the insert plate 31. The insert plate 31 is disposed in the mounting groove 13A, and the two wing plates 33 are respectively located outside the openings at both ends of the through groove.

[0032] In this embodiment, the connecting component 13 of the clamp structure 10 is provided with a mounting groove 13A that extends through both the upper and lower ends. The opening of the mounting groove 13A faces away from the clamp member 11, so that the mounting groove 13A is a through groove with openings at both ends. Furthermore, the insert plate 31 of the I-shaped structure enters the mounting groove 13A from the groove opening until one end of the insert plate 31 abuts against the outer surface of the clamp member 11, ensuring that one end of the insert plate 31 is located as close as possible to the mounting groove 13A, thereby improving the assembly stability of the reinforcing structure 30 and the connecting component 13.

[0033] Optionally, one end of the wing plate 33 is welded to the clamp 11.

[0034] In this embodiment, when the I-shaped insert plate 31 is fully inserted into the mounting groove 13A and one end abuts against the clamp 11, the upper and lower wing plates 33 of the I-shaped structure contact the clamp 11, and the edges of the wing plates 33 are welded and fixed to the clamp 11, so as to improve the overall installation stability of the reinforcement structure 30 and the clamp structure 10 on the basis of tightening the bolts 40.

[0035] Optionally, the opposing surfaces of the two flanges 33 abut against the inner surface of the steel beam.

[0036] In this embodiment, after the first connecting plate 131 and the second connecting plate 133 are installed with the steel beam in the connecting assembly 13, the upper and lower edges of the first connecting plate 131 and the second connecting plate 133 abut or are press-fitted with the inner surface of the steel beam, so that the clamp assembly and the steel beam are fully engaged and the assembly is stable. The opposing surfaces of the upper and lower flanges 33 of the I-shaped structure abut or are press-fitted with the inner surface of the steel beam to strengthen the structural fit between the reinforcing structure 30 and the steel beam, thereby improving the joint reinforcement effect between the steel beam and the steel column 600.

[0037] Optionally, the length of the reinforcing structure 30 is greater than the length of the connecting component 13, so as to increase the contact area between the reinforcing structure 30 and the steel beam and improve the reliability of the reinforcement.

[0038] Furthermore, when dealing with the addition of a steel beam, a reinforcement structure 30 can be provided as a continuous I-beam structure of the same length as the steel beam.
