Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically to a reinforcement structure for steel structure beams in buildings. Background Technology

[0002] Steel structure construction is a new type of building system that breaks down the boundaries between the real estate, construction, and metallurgical industries, integrating them into a new industrial system. This is the steel structure building system that industry insiders are generally optimistic about. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel sections instead of reinforced concrete, resulting in higher strength and better seismic resistance. Due to its advantages such as high strength and fast construction speed, steel structure buildings are widely used in industrial plants, high-rise buildings, and other fields. However, with the increase in service life or the increase in load demand, some steel beams may have insufficient load-bearing capacity, so it is necessary to reinforce the steel beams. At present, steel structure reinforcement technologies mainly include the steel plate bonding method, the external concrete encasing method, and the addition of supports.

[0003] Among them, the steel plate bonding method involves bonding steel plates to the tension zone of the steel beam with epoxy resin adhesive to improve its bending load-bearing capacity. The advantages are small weight increase and fast construction, but long-term use is prone to problems such as adhesive aging and steel plate peeling. The concrete encasing method involves pouring reinforced concrete around the steel beam to form a composite section. The advantage is a significant increase in load-bearing capacity, but the construction period is long, the self-weight increases significantly, and it may affect the building's net height. The additional support method involves adding diagonal braces or trusses to share the load. The advantage is clear force transmission, but it will occupy building space and affect the functionality.

[0004] Therefore, it is necessary to invent a steel beam reinforcement structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforcement structure for steel beams in buildings, so as to solve the problems that reinforcement technologies in the field generally have the problems of complex construction, high cost, impact on building function or insufficient long-term durability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel structure beam reinforcement structure, comprising a steel structure column, a steel beam body welded to the side of the steel structure column, and a reinforcement component provided on the lower side of the steel beam body. The reinforcement component includes a connecting plate, a first connecting hole, a reinforcement plate, a second connecting hole, a first bolt, and stiffening ribs. The connecting plate is L-shaped and welded inside the steel beam body. The reinforcement plate is U-shaped and covers the lower side and front and rear sides of the steel beam body. Multiple sets of stiffening ribs are fixedly connected to the lower surface of the reinforcement plate.

[0007] By adopting the above technical solution, the reinforcing plate is made of Q355B steel with a thickness of 10mm. The first bolt is a 10.9 grade M16 bolt with a hardened steel washer of 3mm thickness on its surface. The reinforcing plate shares the bending moment of the steel beam body, and the connecting plate transmits the shear force to the reinforcing plate, forming a combined force system. The stiffening ribs prevent buckling of the fixed plate and ensure overall stability. While reinforcing the steel beam body, this solution also facilitates installation, reduces installation costs, improves durability, and does not affect the building's functionality.

[0008] Optionally, the first connecting hole is located on the side of the connecting plate, the second connecting hole is located on the side of the reinforcing plate, and the first bolt is located inside the first connecting hole.

[0009] By adopting the above technical solution, the first bolt is passed through the first connecting hole and the second connecting hole to lock and fix the reinforcing plate to the steel beam body.

[0012] Optionally, the surface of the steel structure column is fixedly connected with two sets of fasteners, the fasteners including a support plate, a mounting plate, a second fixing plate, a second fixing hole, a locking plate, a locking hole, and a locking bolt.

[0013] By adopting the above technical solution, two sets of fasteners are wrapped around both sides of the steel structure column, and the two sets of fasteners are tightly fixed to the surface of the steel structure column by locking bolts, which supports the reinforcement plate and the steel beam body, and further improves the stability of the connection between the steel beam body and the reinforcement plate and the steel structure column.

[0014] Optionally, the support plate is U-shaped, the mounting plate is fixedly connected to the upper end of the side of the support plate, and a diagonal brace is fixedly connected between the mounting plate and the side wall of the support plate.

[0015] By adopting the above technical solution, the diagonal brace improves the stability of the connection between the mounting plate and the support plate, and increases the support strength of the mounting plate.

[0016] Optionally, a second fixing plate is fixedly connected to both the front and rear ends of the upper surface of the mounting plate, and the second fixing hole is formed on the surface of the second fixing plate.

[0017] By adopting the above technical solution, the first fixing plates at both ends of the reinforcing plate are mounted on the upper surface of the mounting plate, and the first fixing plates and the second fixing plates are connected by passing the second bolt through the first fixing hole and the second fixing hole, thereby improving the stability of the connection between the reinforcing plate and the fastener.

[0018] Optionally, both ends of the support plate are fixedly connected to locking plates, and multiple sets of locking holes are opened on the surface of both sets of locking plates.

[0019] Optionally, the locking bolt is disposed inside the locking hole.

[0020] By adopting the above technical solution, the locking bolts are passed through the interior of the two sets of locking holes on the same side of the two sets of fasteners, thus fixing the fasteners to the surface of the steel structure column.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. This utility model fixes the reinforcing plate to the lower side of the steel beam body. The reinforcing plate shares the bending moment of the steel beam body, and the connecting plate transmits the shear force to the reinforcing plate, forming a combined force system. The stiffening ribs prevent the reinforcing plate from buckling and ensure overall stability. It is easy to install, reduces installation costs and improves durability, and does not affect the building's functionality.

[0023] 2. This utility model supports both ends of the reinforcing plate and the steel beam body by fixing the fastener to the surface of the steel beam body, and uses a second bolt to connect and fix the fastener to the reinforcing plate, which effectively improves the connection strength between the reinforcing plate and the steel structure column. At the same time, the bolt combination connection means that when the load-bearing capacity of the reinforcing plate decreases, it can be disassembled and re-reinforced without increasing the weight of the steel structure building again or damaging the surface of the steel structure, thus realizing resource reuse.

[0031] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0032] This utility model provides, for example Figures 1 to 3 The diagram shows a steel beam reinforcement structure, including a steel column 1. A steel beam body 2 is welded to the side of the steel column 1. A reinforcement component is provided on the lower side of the steel beam body 2. The reinforcement component includes a connecting plate 21, a first connecting hole 22, a reinforcement plate 3, a second connecting hole 31, a first bolt 32, and stiffening ribs 33. The connecting plate 21 is L-shaped and welded inside the steel beam body 2. The reinforcement plate 3 is U-shaped and covers the lower side and front and rear sides of the steel beam body 2. Multiple sets of stiffening ribs 33 are fixedly connected to the lower surface of the reinforcement plate 3. The first connecting hole 22 is opened on the side of the connecting plate 21, the second connecting hole 31 is opened on the side of the reinforcement plate 3, and the first bolt 32 is located inside the first connecting hole 22.

[0033] During installation, firstly, first connecting holes 22 and second connecting holes 31 are made on the surfaces of connecting plate 21 and reinforcing plate 3, respectively. Then, the surface of the steel beam body 2 is cleaned to remove rust and contaminants. Next, the welding position of connecting plate 21 is determined, and connecting plate 21 is welded and fixed to steel beam body 2. Then, reinforcing plate 3 is placed against the lower surface of steel beam body 2, and both sides of reinforcing plate 3 are wrapped around both sides of steel beam body 2, aligning the first connecting holes 22 and second connecting holes 31. Then, temporary fixing device is used to temporarily fix reinforcing plate 3, and multiple sets of first bolts 32 are fixed in sequence. The reinforcing plate 3 is connected and fixed to steel beam body 2 by the cooperation of connecting plate 21 and first bolts 32. After all first bolts 32 are fixed, the temporary fixing device is removed.

[0034] See Figure 1 , Figures 3 to 5Three sets of first fixing plates 34 are fixedly connected to both ends of the reinforcing plate 3. The surfaces of the front and rear sets of first fixing plates 34 are provided with first fixing holes 35. The first fixing holes 35 are provided with second bolts 36. Two sets of fasteners 4 are fixedly connected to the surface of the steel structure column 1. The fasteners 4 include a support plate 41, a mounting plate 42, a second fixing plate 43, a second fixing hole 44, a locking plate 46, a locking hole 47, and a locking bolt 48. The support plate 41 is U-shaped. The mounting plate 42 is fixedly connected to the upper end of the side of the support plate 41. A diagonal brace 45 is fixedly connected between the mounting plate 42 and the side wall of the support plate 41. The front and rear ends of the upper surface of the mounting plate 42 are fixedly connected to the second fixing plates 43. The second fixing holes 44 are opened on the surface of the second fixing plates 43. The two ends of the support plate 41 are fixedly connected to the locking plates 46. The surfaces of the two sets of locking plates 46 are provided with multiple sets of locking holes 47. The locking bolts 48 are located inside the locking holes 47.

[0035] In addition, after fixing the reinforcing plate 3 to the steel beam body 2, two sets of fixing parts 4 are wrapped around both sides of the steel structure column 1, and the locking bolts 48 are passed through the two sets of locking holes 47 on the same side to temporarily fix the two sets of fixing parts. Then, the fixing parts 4 are slid upward so that the upper surface of the mounting plate 42 abuts against the lower end of the first fixing plate 34. At this time, multiple sets of locking bolts 48 are tightened to tightly fix the two sets of fixing parts 4 to the steel structure column 1. The fixing parts 4 are used to support the ends of the reinforcing plate 3 and the steel beam body 2, improve the connection strength between the reinforcing plate 3 and the steel beam body 2 and the steel structure column 1, and reinforce the connection between the steel beam body 2 and the steel structure column 1.

[0036] At the same time, after the fastener 4 is locked, the first fixing hole 35 and the second fixing hole 44 will be aligned. At this time, the second bolt 36 is passed through the first fixing hole 35 and the second fixing hole 44 to lock and fix the first fixing plate 34 and the second fixing plate 43, thereby fixing both ends of the reinforcing plate 3 to the reinforcing part 4 and the steel structure column 1, and making it convenient to replace the reinforcing plate 3 when the support is insufficient in the future.

[0037] The working principle of this utility model is as follows: By fixing the reinforcing plate 3 to the lower side of the steel beam body 2, the reinforcing plate 3 shares the bending moment of the steel beam body 2, and the connecting plate 21 transmits the shear force to the reinforcing plate 3, forming a combined force system. The stiffening rib 33 prevents the reinforcing plate 3 from buckling, ensuring overall stability. This facilitates installation, reduces installation costs, and improves durability without affecting the building's functionality. At the same time, by fixing the fastener 4 to the surface of the steel beam body 2, the two ends of the reinforcing plate 3 and the steel beam body 2 are supported. The fastener 4 is connected and fixed to the reinforcing plate 3 using the second bolt 36, effectively improving the connection strength between the reinforcing plate 3 and the steel structure column 1. Furthermore, the bolt combination connection allows the reinforcing plate 3 to be disassembled and re-reinforced when its load-bearing capacity decreases, without increasing the weight of the steel structure building or damaging the steel structure surface, thus enabling resource reuse.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
