Description

Technical Field

[0001] This utility model relates to the technical field of steel structure connection components, specifically to a steel structure fatigue-resistant connection component with a buffer layer. Background Technology

[0002] Steel structure connection assemblies are key components used to connect and secure various parts in steel structure engineering. Their performance and quality directly affect the safety and stability of the steel structure. Bolted connection assemblies achieve friction-type or bearing-type connections through pre-tightening force and are suitable for large-span, heavy-load structures; gusset plates are used for beam-column connections or truss nodes to enhance local load-bearing capacity; clamps / hoops are used to fix pipes or structural steel, such as bridge cable connections.

[0003] Existing steel structure connection components do not have a buffering effect when vibration occurs in the support of the rod, which easily leads to stress concentration and damage. They also have poor fatigue resistance and are prone to deformation and damage. Utility Model Content

When vibration occurs in the support of the steel structure, the connection component has a buffering effect, avoiding stress concentration and damage. It has a significant fatigue resistance, is not easily deformed or damaged, and is durable.

[0005] The technical solution adopted by this utility model to solve its technical problem is a steel structure fatigue-resistant connection component with a buffer layer, including a fatigue-resistant reinforcing plate, an arc-shaped base plate, a buffer pad and an arc-shaped clamping plate. The top of the arc-shaped base plate is welded with a fatigue-resistant reinforcing plate, and a longitudinal reinforcing rib is welded to the top of the fatigue-resistant reinforcing plate and along its longitudinal middle part. Triangular fixing plates are welded at equal distances between the two sides of the longitudinal reinforcing rib and the top of the fatigue-resistant reinforcing plate. Fixed end blocks are welded to both ends of the arc-shaped base plate, and through holes are opened at both ends of the fixed end blocks.

[0006] The bottom two ends of the arc-shaped base plate are fitted with arc-shaped clamping plates. The top two sides of the arc-shaped clamping plates are welded with movable end blocks. The top two ends of the movable end blocks are welded with fixing screws. Buffer pads are adhered to both ends of the arc-shaped base plate and the inner surface of the arc-shaped clamping plates.

[0007] By adopting the above technical solution, the steel structure connection component has a buffering effect when vibration occurs in the support of the rod, avoiding stress concentration and damage, with significant fatigue resistance, not easy to deform or damage, and durable.

[0008] Specifically, the fixing screw passes through the through hole, and a locking nut is screwed onto the top of the fixing screw, with the locking nut located on the top of the fixing end block.

[0009] By adopting the above technical solution, the locking nuts are tightened and the fixing screws are tightened respectively, so that the arc-shaped clamping plate is locked at the end of the steel structure member, thereby realizing the rapid connection of the member.

[0010] Specifically, a washer is fitted on the fixing screw and the washer is located between the locking nut and the fixing end block.

[0011] Specifically, the cushioning pad is made of PU material.

[0012] By adopting the above technical solution, the buffer pad is made of PU material, which has a certain elasticity and toughness, good anti-slip effect, and buffering effect when vibration occurs in the support of the rod.

[0013] Specifically, end support plates are welded between both ends of the fatigue-resistant reinforcing plate and the arc-shaped base plate.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To ensure that the steel structure connection components act as a buffer when vibrations occur in the support members, preventing stress concentration and damage, they exhibit significant fatigue resistance, are not easily deformed or damaged, and are durable. Figure 1-3 As shown, the present invention discloses a steel structure fatigue-resistant connection assembly with a buffer layer, comprising a fatigue-resistant reinforcing plate 3, an arc-shaped base plate 10, a buffer pad 12, and an arc-shaped clamping plate 11. The top of the arc-shaped base plate 10 is welded with the fatigue-resistant reinforcing plate 3, and a longitudinal reinforcing rib 2 is welded to the top of the fatigue-resistant reinforcing plate 3 and along its longitudinal middle portion. Triangular fixing plates 1 are welded at equal distances between the two sides of the longitudinal reinforcing rib 2 and the top of the fatigue-resistant reinforcing plate 3. Fixing end blocks 7 are welded to both ends of the arc-shaped base plate 10, and through holes 13 are opened at both ends of the fixing end blocks 7.

[0024] The bottom two ends of the arc-shaped base plate 10 are fitted with arc-shaped clamping plates 11. Movable end blocks 9 are welded to both sides of the top of the arc-shaped clamping plates 11. Fixed screws 8 are welded to both ends of the top of the movable end blocks 9. Buffer pads 12 are adhered to both ends of the arc-shaped base plate 10 and the inner surface of the arc-shaped clamping plates 11.

[0025] When in use, the steel structure connection components act as a buffer when vibration occurs in the support of the rods, avoiding stress concentration and damage. They have a significant fatigue resistance, are not easily deformed or damaged, and are durable.

[0026] For example, such as Figure 1 , 3 As shown, the present invention also includes a fixing screw 8 that passes through the through hole 13, and a locking nut 5 that is screwed onto the top of the fixing screw 8 and is located on the top of the fixing end block 7.

[0027] In use, tighten the locking nut 5 and tighten the fixing screw 8 respectively, so that the arc-shaped clamping plate 11 is locked at the end of the steel structure member, thereby realizing the quick connection of the member.

[0028] For example, such as Figure 1As shown, the present invention also includes a washer 6 sleeved on the fixing screw 8 and the washer 6 being located between the locking nut 5 and the fixing end block 7.

[0029] When using the product, the washer 6 serves to prevent slippage when tightening the locking nut 5.

[0030] For example, such as Figure 1 As shown, the present invention also includes a cushioning pad 12 specifically made of PU material.

[0031] When in use, the buffer pad 12 is made of PU material, which has a certain degree of elasticity and toughness, good anti-slip effect, and buffering effect when vibration occurs in the support of the rod.

[0032] For example, such as Figure 1 As shown, the present invention also includes end support plates 4 welded between the two ends of the fatigue-resistant reinforcing plate 3 and the arc-shaped base plate 10.

[0033] During use, the end support plate 4 serves as a support and positioning element, further enhancing the strength and rigidity between the fatigue-resistant reinforcing plate 3 and the arc-shaped base plate 10.

[0034] In use, the two sets of steel structure members are respectively inserted into the locking holes between the arc-shaped clamping plates 11 and the arc-shaped base plate 10 at both ends, and the ends of the two sets of steel structure members are in contact with each other. The locking nuts 5 are tightened and the fixing screws 8 are tightened, so that the arc-shaped clamping plates 11 are locked at the ends of the steel structure members, thereby realizing the rapid connection of the members.

[0035] The buffer pad 12 is made of PU material, which has a certain degree of elasticity and toughness, good anti-slip effect, and buffers when vibration occurs in the support of the rod, so as to avoid stress concentration and damage.

[0036] The anti-fatigue reinforcing plate 3 welded to the top of the arc-shaped base plate 10, along with the longitudinal reinforcing ribs 2 and triangular fixing plates 1 on the top of the anti-fatigue reinforcing plate 3, greatly improves the strength and rigidity of the connecting assembly, resulting in significant anti-fatigue effects, resistance to deformation and damage, and durability.
