Description

Technical Field

[0001] This utility model relates to a steel structure building connector with shock absorption function, belonging to the field of installation engineering technology. Background Technology

[0002] In steel structure buildings, connectors are the core components for connecting and fixing steel components, directly affecting the overall structural stability and load-bearing capacity of the building. They are widely used in industrial plants, high-rise buildings, large-span stadiums, and other scenarios. As the construction industry's requirements for structural safety and disaster resistance increase, connectors not only need to have high-strength load-bearing capacity, but also need to be able to withstand external impacts that the building may face during its service life, or the micro-deformation of components caused by temperature changes and load fluctuations during long-term use. In particular, when components such as mounting rods in the connectors show a tendency to bend, they need to use shock absorption and buffering functions to offset stress and avoid structural safety hazards caused by connector breakage.

[0003] Existing steel structure connectors are usually rigid connections, mainly consisting of bolts, welded joints, or integrated cast steel parts. They transfer loads through the rigid contact of metal components, resulting in a stable structure but lacking vibration damping capabilities. They are only suitable for scenarios with stable loads and no significant vibrations. Some steel structure connectors are equipped with simple buffer connectors, which add elastic components such as rubber pads at the connection joints to absorb some of the impact force through the deformation of elastic materials.

[0004] However, the elastic components of existing steel structure connectors are mostly localized and cannot specifically address the bending stress of the mounting rods. Furthermore, materials such as rubber are prone to aging and failure after long-term use, resulting in a rapid decline in the cushioning effect. Therefore, other structures with shock absorption functions are needed to replace them. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a steel structure building connector with shock absorption function that prevents excessive displacement and detachment of components, offsets stress, and prevents breakage of rods.

[0006] The present invention adopts the following technical solution:

[0007] This utility model of a steel structure building connector with shock absorption function includes a fixed crossbar, a mounting rod vertically fixed in the middle of the fixed crossbar, shock absorption components disposed on the left and right sides of the fixed crossbar, and a buffer component disposed on the top outer side of the fixed crossbar between the corresponding shock absorption components.

[0008] The present invention has two shock-absorbing components symmetrically arranged around the centerline of a fixed crossbar. Each shock-absorbing component includes a buffer groove on the top surface of one side of the fixed crossbar, a sliding limiting rod installed in the buffer groove, a sliding constraint block that is loosely fitted onto the sliding limiting rod, and buffer springs installed between the left and right ends of the sliding constraint block and the corresponding inner walls of the buffer groove. Both buffer springs are loosely fitted onto the sliding limiting rod. The sliding limiting rod is arranged along the length of the fixed crossbar, and the buffer groove has a rectangular cross-section. Two lugs A are installed on the top surface of the sliding constraint block, and pins A are installed on the two lugs A.

[0009] This utility model has two buffer components symmetrically arranged around the centerline of the fixed crossbar; two lugs B are installed on both sides of the top of the fixed rod, and pins B are installed on the two lugs B; the buffer components include an upper fixed rod hinged to pins B, an upper constraint plate fixedly installed at the bottom of the upper fixed rod, a lower constraint rod hinged to pins A, a lower constraint plate fixedly installed at the top of the lower constraint rod and in contact with the upper constraint plate, and anti-breakage components provided on the upper and lower constraint plates; the lower end of the upper constraint plate corresponds to the upper end of the lower constraint rod and is spaced apart, and the upper end of the lower constraint plate corresponds to the lower end of the upper fixed rod and is spaced apart.

[0010] This utility model anti-fracture component includes an upper sliding hole along the length of the upper constraint plate, a lower sliding hole along the length of the lower constraint plate that corresponds to and overlaps with the upper sliding hole, an upper constraint groove on the outer wall of the upper constraint plate, a lower constraint groove on the outer wall of the lower constraint plate, a fixing block embedded in the upper constraint groove and the lower constraint groove respectively, a screw passing through the upper sliding hole and the lower sliding hole and fixed to the corresponding fixing block, and a locking nut screwed to the outer end of the corresponding screw; the upper constraint groove is located outside the upper sliding hole, and the lower constraint groove is located outside the lower sliding hole.

[0011] This utility model provides a sliding connection hole in the middle of the sliding constraint block for the sliding limit rod to pass through. Spring limit grooves communicating with the sliding connection hole are provided at both ends of the sliding connection hole. The inner diameter of the spring limit groove and the outer diameter of the buffer spring are both larger than the inner diameter of the sliding connection hole. One end of the buffer spring abuts against the inner end of the spring limit groove.

[0012] This utility model has an installation groove on the inner side of the mounting rod.

[0013] The beneficial effects of this utility model are as follows: When the fixed rod installed by this utility model bends, the bidirectional displacement of the upper and lower constraint plates adapts to the stress direction, and with the mechanical limiting of the two screws, the fixed rod is prevented from excessive displacement and detachment. At the same time, the sliding constraint block moves along the sliding limit rod, and the elastic deformation of the buffer spring absorbs the bending impact energy, gradually offsetting the stress and effectively protecting the fixed rod from breakage. The overall design balances connection stability and shock absorption reliability, improving the disaster resistance and durability of steel structure buildings. Attached Figure Description

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Example 1:

[0025] As attached Figure 1-4 As shown, the steel structure building connector with shock absorption function in this embodiment includes a fixed crossbar 1, a mounting rod 7 vertically fixed in the middle of the fixed crossbar 1, shock absorption components on the left and right sides of the fixed crossbar 1, and a buffer component between the top outer side of the fixed crossbar 1 and the corresponding shock absorption component; an installation groove 16 is opened on the inner side of the mounting rod 7.

[0026] Two damping components are symmetrically arranged around the centerline of the fixed crossbar 1. The damping components include a buffer groove 2 on the top surface of one side of the fixed crossbar 1, a sliding limit rod 5 installed in the buffer groove 2, a sliding constraint block 3 that is loosely fitted on the sliding limit rod 5, and buffer springs 6 installed between the left and right ends of the sliding constraint block 3 and the corresponding inner walls of the buffer groove 2. Both buffer springs 6 are loosely fitted on the sliding limit rod 5. The sliding limit rod 5 is arranged along the length of the fixed crossbar 1, and the buffer groove 2 has a rectangular cross-section. Two lugs A4 are installed on the top surface of the sliding constraint block 3, and pins A41 are installed on the two lugs A4.

[0027] A sliding connection hole 19 is provided in the middle of the sliding constraint block 3 so that the sliding limit rod 5 can pass through. Spring limit grooves 20 communicating with the sliding connection hole 19 are provided at both ends of the sliding connection hole 19. The inner diameter of the spring limit groove 20 and the outer diameter of the buffer spring 6 are both larger than the inner diameter of the sliding connection hole 19. One end of the buffer spring 6 abuts against the inner end of the spring limit groove 20.

[0028] Example 2:

[0029] As attached Figure 3-6 As shown, this embodiment is a further improvement based on Embodiment 1, specifically:

[0030] The two buffer components are symmetrically arranged around the center line of the fixed crossbar 1; two lugs B8 are installed on both sides of the top of the mounting rod 7, and pins B81 are installed on the two lugs B8.

[0031] The buffer assembly includes an upper fixing rod 9 hinged to pin B81, an upper constraint plate 10 fixedly installed at the bottom of the upper fixing rod 9, a lower constraint rod 12 hinged to pin A41, a lower constraint plate 13 fixedly installed at the top of the lower constraint rod 12 and in contact with the upper constraint plate 10, and anti-breakage components provided on the upper constraint plate 10 and the lower constraint plate 13. The lower end of the upper constraint plate 10 corresponds to the upper end of the lower constraint rod 12 with a gap. There is a certain gap at the corresponding mating position of the lower end of the upper constraint plate 10 and the upper end of the lower constraint rod 12. This gap provides a certain space for the entire upper constraint plate 10 to move, avoiding obstruction and interference when the upper constraint plate 10 moves. There is a certain gap at the corresponding mating position of the upper end of the lower constraint plate 13 and the lower end of the upper fixing rod 9. This gap provides a certain space for the entire lower constraint plate 13 to move, avoiding obstruction and interference when the lower constraint plate 13 moves.

[0032] The anti-fracture component includes an upper sliding hole 101 along the length of the upper constraint plate 10, a lower sliding hole 131 along the length of the lower constraint plate 13 corresponding to and overlapping the upper sliding hole 101, an upper constraint groove 11 on the outer wall of the upper constraint plate 10, a lower constraint groove 14 on the outer wall of the lower constraint plate 13, fixing blocks 15 respectively embedded in the upper constraint groove 11 and the lower constraint groove 14, screws 17 passing through the upper sliding hole 101 and the lower sliding hole 131 and fixed to the corresponding fixing blocks 15, and a locking nut 18 screwed to the outer end of the corresponding screw 17, as shown in the attached figure. Figure 1 , 2 As shown, two locking nuts 18 are arranged obliquely opposite each other; the upper constraint groove 11 is arranged outside the upper sliding hole 101, and the lower constraint groove 14 is arranged outside the lower sliding hole 131; the upper constraint groove 11 is located obliquely below the lower constraint groove 14, that is, the upper constraint groove 11 and the lower constraint groove 14 are staggered, that is, the fixing block 15 in the lower constraint groove 14 is located obliquely above the fixing block 15 in the upper constraint groove 11. The two screws 17 are arranged parallel and adjacent to each other. Under the action of the two screws 17, the displacement distance of the entire upper constraint plate 10 and the lower constraint rod 12 can be limited.

[0033] During operation, the upper constraint plate 10 and the lower constraint plate 13 are in a relatively parallel and fitted state. The sliding constraint block 3 is sleeved on the sliding limit rod 5 inside the buffer groove 2 through the sliding connection hole 19. The buffer spring 6 inside the spring limit groove 20 is in a naturally extended state. The two ends of the buffer spring 6 are respectively fitted with the spring limit groove 20 and the inner wall of the buffer groove 2, reserving deformation space for subsequent shock absorption. At the same time, the fixing blocks 15 inside the upper constraint groove 11 and the lower constraint groove 14 are locked by the corresponding screws 17 and locking nuts 18 to ensure that the initial relative position of the upper constraint plate 10 and the lower constraint plate 13 is stable and to avoid loosening under non-stress conditions.

[0034] When the mounting rod 7 is subjected to external force and tends to bend, it will cause the ear seats B 8 and pins B 81 on both sides to move synchronously, thereby causing the upper fixing rod 9 and the upper constraint plate 10 to move in both directions. The upper fixing rod 9 on the bent side of the mounting rod 7 will tilt towards the lower constraint rod 12 in the direction of bending, causing the upper constraint plate 10 to move closer to the lower constraint plate 13. Since the lower constraint plate 13 is hinged to the pin A 41 on the ear seat A 4 through the lower constraint rod 12, the lower constraint rod 12 and the sliding constraint block 3 will form a rotational relationship on the ear seat A 4, allowing the lower constraint plate 12 to rotate slightly around the pin A 41. The downward movement of the upper constraint plate 10 is transmitted to the lower constraint plate 13 through the fixing block 15, so that the lower constraint plate 13 can make adaptive fine adjustments with the tilt of the upper constraint plate 10, avoiding local stress concentration that could lead to component damage.

[0035] On the other side of the bent mounting rod 7, the upper mounting rod 9 tilts away from the lower constraint rod 12, causing the upper constraint plate 10 to move away from the lower constraint plate 13. At this time, the fixing block 15 inside the upper constraint groove 11 moves with the upper constraint plate 10, thereby pulling the screw 17 connected to it closer to the screw 17 connected to the fixing block 15 embedded in the upper constraint groove 11, until the two screws 17 are completely in contact. The contact of the screws 17 forms a mechanical limit, preventing the upper constraint plate 10 from moving further away, thus avoiding the connection from detaching due to excessive displacement.

[0036] When the screw 17 on the far side is engaged, the far-moving movement of the upper constraint plate 10 is restricted. The subsequent bending stress will be transmitted to the pin A 41 connected to the ear seat A 4 through the lower constraint plate 13 and the lower constraint rod 12. The lower constraint rod 12 pushes the sliding constraint block 3 to move along the sliding limit rod 5 through the ear seat A 4 and the pin A 41. The sliding constraint block 3 cooperates with the sliding limit rod 5 through the sliding connection hole 19 and can only move along the axial direction of the sliding limit rod 5. Under the push of the bending stress, the sliding constraint block 3 moves towards the buffer spring 6 inside the buffer groove 2 to compress the buffer spring 6.

[0037] The buffer spring 6 is sleeved on the sliding limit rod 5. Its deformation process can absorb the impact energy generated by bending. When the sliding constraint block 3 squeezes the buffer spring 6, the buffer spring 6 converts mechanical energy into elastic potential energy through its own elastic deformation, gradually offsetting the bending stress. At the same time, the cooperation between the sliding limit rod 5 and the sliding connection hole 19 can prevent the sliding constraint block 3 from shifting when it moves, ensuring that the deformation of the buffer spring 6 is uniform and the shock absorption effect is stable. When the external bending stress disappears, the buffer spring 6 releases the stored elastic potential energy, pushing the sliding constraint block 3 to move in the opposite direction along the sliding limit rod 5 and return to the initial position.
