Description

Technical Field

[0001] The invention belongs to the technical field of civil engineering, and specifically relates to an anti-slip structure of a steel bracket for supporting beams. Background Art

[0002] In a building structure system, a steel bracket, as a key component for supporting beams, plays an important role in transferring the load on the beam to the main structure. Its anti-slip structure ensures that there is no relative displacement between the steel bracket and the supporting beam under external forces such as wind loads and seismic actions by enhancing the connection reliability, thus guaranteeing the overall safety of the building.

[0003] Traditionally, welding or threaded connection methods are generally used to fix the steel bracket and the supporting beam. However, welding connections are prone to cracks due to defects such as weld porosity, slag inclusion, and incomplete penetration. Moreover, the heat-affected zone can also degrade the properties of the steel, and the welding residual stress can reduce the fatigue strength and brittle fracture resistance of the structure. In bolt connections, due to the clearance between the bolt holes and bolts, there is collision and wear, and bolts are prone to loosen under dynamic loads. Therefore, relying solely on bolt connections is difficult to effectively achieve the anti-slip effect. Thus, an anti-slip structure of a steel bracket for supporting beams is proposed to solve the problems raised in the background art. Summary of the Invention

[0013] Preferably, two inclined blocks are symmetrically and movably connected inside the steel bracket body. A third elastic member is fixedly connected to each of the opposite sides of the two inclined blocks. The inclined blocks are elastically connected to the steel bracket body through the third elastic members.

[0014] Preferably, the bottom end of the inclined block is beveled. One end of each of the two inclined blocks extends into the first circular groove of the steel bracket body. A square groove for circumferentially limiting the push rod is formed on the inner wall of the steel bracket body.

[0015] Preferably, the second clamping groove is composed of a cross groove and a second circular groove. The cross groove of the second clamping groove is adapted to the cross block. The cross block penetrates through the outer wall of the top end of the steel bracket body and extends to the outside of the steel bracket body. The cross block can be clamped into the second circular groove through the cross groove.

[0016] Preferably, the bottom end of the first elastic member is fixedly connected inside the steel bracket body. The first elastic member is used to squeeze the rectangular block and keep the rectangular block in a trend of moving upward. A second elastic member is movably sleeved on the outside of the first round rod. Two ends of the second elastic member are respectively fixedly connected to the rectangular block and the square block.

[0017] Preferably, the bottom end of the square block is sleeved on the outside of the first round rod. A second round rod is fixedly connected to the top end of the square block. Straight grooves are formed on both sides of the bottom end of the clamping plate. The second round rod penetrates through the straight grooves and is movably clamped inside the inclined grooves.

When the support beam body squeezes the rectangular block downward, the rectangular block drives the second elastic member to move downward together through the first round rod. Through the cooperation between the second round rod and the inclined groove, when the second elastic member moves downward, it can drive the clamping plate to move towards the support beam body, and then drive the gasket to abut against the side wall of the support beam body, thereby clamping and limiting both sides of the support beam body, further restricting the movement of the support beam body in the horizontal direction, reducing the possibility of displacement of the support beam body, and improving the stability of the entire structure.

[0022] Through the cooperation between structures such as the arc groove, the cross-shaped block, the push rod, and the second card slot, the present invention improves the stability and anti-slip ability of the structure. After the cross-shaped block is inserted into the inner part of the second circular groove of the second card slot through the cross-shaped groove, the circumferential limit of the circular groove on the cross-shaped block is released. At this time, through the cooperation between the connecting column of the push rod and the arc groove, when the push rod moves upward, it can drive the rotating cylinder to rotate, and then the rotating cylinder drives the cross-shaped block to rotate by 45 degrees inside the second circular groove, so that the trajectory of the rotated cross-shaped block is misaligned with the cross-shaped groove, and an embedded connection is formed between the support beam body and the steel corbel body, thereby increasing the contact area and bite force between the two, and improving the stability and anti-slip ability of the structure.

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1 to 6 shown, the present invention provides an anti-slip structure for a steel bracket of a support beam, including a steel bracket body 1, and further including:

[0032] A clamping assembly 2, the clamping assembly 2 is movably connected to the steel bracket body 1;

[0033] A limiting assembly 3, the limiting assembly 3 is movably connected inside the steel bracket body 1;

[0034] A support beam body 4, the support beam body 4 is placed on the top of the steel bracket body 1, and a second card slot 5 is opened at the bottom of the support beam body 4;

[0035] Among them, the clamping assembly 2 includes a rectangular block 21, the bottom of the rectangular block 21 is fixedly connected with a first elastic member 22, both sides of the first elastic member 22 are fixedly connected with a first round rod 23, two square blocks 25 are symmetrically and movably connected inside the steel bracket body 1, the top end of the square block 25 is fixedly connected with a second round rod 26, the outside of the square block 25 is movably sleeved with a clamping plate 27, and a spacer 28 is fixedly connected to the opposite side of the two clamping plates 27;

[0036] The limiting assembly 3 includes a rotating cylinder 31, two arc grooves 32 are annularly opened on the inner wall of the rotating cylinder 31, and a cross block 33 is fixedly connected to the top of the rotating cylinder 31.

[0037] Adopting the above solution: By squeezing the rectangular block 21 downward through the support beam body 4, the rectangular block 21 drives the second elastic member 24 to move downward together through the first round rod 23. Through the cooperation of the second round rod 26 and the inclined groove 29, when the second elastic member 24 moves downward, it can drive the clamping plate 27 to move toward the support beam body 4, and then drive the gasket 28 to abut against the side wall of the support beam body 4, so as to clamp and limit both sides of the support beam body 4, and further limit the movement of the support beam body 4 in the horizontal direction, thereby reducing the possibility of displacement of the support beam body 4 and improving the stability of the entire structure.

[0038] As Figure 4 and Figure 6 As shown, a push rod 34 is movably connected inside the rotating cylinder 31. Two connecting columns are annularly arranged at the top end of the outer wall of the push rod 34. The connecting columns are movably clamped inside the arc groove 32. The arc groove 32 is at a forty-five-degree angle. The bottom end of the push rod 34 penetrates through the outer wall of the steel bracket body 1 and extends to the outside of the steel bracket body 1. Two first clamping grooves 35 are symmetrically arranged at the bottom end of the push rod 34. A first circular groove adapted to the bottom end of the push rod 34 is opened at the bottom of the steel bracket body 1. Two inclined blocks 36 are symmetrically and movably connected inside the steel bracket body 1. A third elastic member 37 is fixedly connected to the opposite side of the two inclined blocks 36. The inclined blocks 36 are elastically connected to the steel bracket body 1 through the third elastic member 37.

[0039] Adopting the above solution: Through the design of the inclined block 36 and the third elastic member 37, its function is that when the push rod 34 moves upward and is completely inserted into the first circular groove, at this time, the inclined block 36 will be clamped into the first clamping groove 35 under the action of the elastic force of the third elastic member 37, so as to limit the position of the push rod 34 after moving upward, and further improve the overall convenience of the device structure.

[0040] As Figure 4 and Figure 6 As shown, the bottom end of the inclined block 36 is beveled. The opposite ends of the two inclined blocks 36 extend into the first circular groove of the steel bracket body 1. A square groove 38 for circumferentially limiting the push rod 34 is opened on the inner wall of the steel bracket body 1. The second clamping groove 5 is composed of a cross groove and a second circular groove. The cross groove of the second clamping groove 5 is adapted to the cross block 33. The cross block 33 penetrates through the outer wall of the top end of the steel bracket body 1 and extends to the outside of the steel bracket body 1. The cross block 33 can be clamped into the second circular groove through the cross groove.

[0041] Adopting the above solution: After the cross block 33 is clamped into the inner part of the second circular groove of the second clamping groove 5 through the cross groove, the circumferential limit of the circular groove on the cross block 33 is released. At this time, through the cooperation of the connecting column of the push rod 34 and the arc groove 32, when the push rod 34 moves upward, it can drive the rotating cylinder 31 to rotate. Furthermore, the rotating cylinder 31 drives the cross block 33 to rotate inside the second circular groove. Since the radian of the arc groove 32 is 45 degrees, after the rotating cylinder 31 drives the cross block 33 to rotate 45 degrees, the track of the cross block 33 will be misaligned with the cross groove, so that the cross block 33 is clamped inside the support beam body 4 and limits the support beam body 4 in the vertical direction. Furthermore, an embedded connection is formed between the support beam body 4 and the steel bracket body 1, thereby increasing the contact area and bite force between the two, and further improving the structural stability and anti-slip ability.

[0042] As Figure 2 、 Figure 3 and Figure 5 shown, the bottom end of the first elastic member 22 is fixedly connected inside the steel bracket body 1. The first elastic member 22 is used to extrude the rectangular block 21 and keep the rectangular block 21 in a trend of moving upward. The outer part of the first round rod 23 is movably sleeved with a second elastic member 24. The two ends of the second elastic member 24 are respectively fixedly connected with the rectangular block 21 and the square block 25. The bottom end of the square block 25 is sleeved outside the first round rod 23. The top end of the square block 25 is fixedly connected with a second round rod 26. Straight grooves are respectively opened on both sides of the bottom end of the clamping plate 27. The second round rod 26 passes through the straight groove and is movably clamped inside the inclined groove 29.

[0043] Adopting the above solution: Through the design of the first elastic member 22, its function is that the first elastic member 22 is used to provide an upward force for the rectangular block 21, so as to ensure that there is a gap between the top of the rectangular block 21 and the top of the steel bracket body 1 even when the rectangular block 21 is not extruded by an external force, thereby ensuring the normal operation of the device;

[0044] Through the design of the second elastic member 24, its function is that the second elastic member 24 is used to extrude the square block 25 and keep the square block 25 moving away from the rectangular block 21, so that the second round rod 26 can be located at the top end of the inclined groove 29 in the initial state, thereby ensuring the smooth progress of subsequent clamping operations.

[0045] As Figures 1 to 3 and Figure 5As shown, the top end of the clamping plate 27 is located outside the steel bracket body 1. One side of the gasket 28 is corrugated. The gasket 28 is made of rubber material. Internal thread grooves are provided on the surfaces of the clamping plate 27, the gasket 28 and the support beam body 4. The top end of the rectangular block 21 penetrates through the outer wall of the steel bracket body 1 and extends to the outside of the steel bracket body 1. There is a gap between the top end of the rectangular block 21 and the top of the steel bracket body 1. A rectangular groove for horizontally limiting the clamping plate 27 is provided on the surface of the steel bracket body 1.

[0046] Adopting the above solution: Internal thread grooves are provided on the surfaces of the clamping plate 27, the gasket 28 and the support beam body 4. Its function is that when the clamping plate 27 with the gasket 28 abuts against the side wall of the support beam body 4, at this time, the operator passes the bolt assembly through the two clamping plates 27, so that the two clamping plates 27 are tightly connected to the support beam body 4, thereby improving the stability of the device. The operator can, according to actual needs, also fix the support beam body 4 to the steel bracket body 1 through the bolt assembly at other positions.

[0047] The working principle and usage process of the present invention: First, the operator uses an external hoisting mechanism to place the support beam body 4 on the top of the steel bracket body 1. When the support beam body 4 is placed on the top of the steel bracket body 1, the cross block 33 will be stuck into the inside of the second card slot 5, thereby limiting the placement position of the support beam body 4 in the initial state, so that the support beam body 4 is placed in the center.

[0048] While the support beam body 4 is being placed, it will also abut against the top of the rectangular block 21, so that the rectangular block 21 drives the two first round rods 23 to move downward under the extrusion of the support beam body 4. Furthermore, the second elastic member 24 sleeved outside the first round rod 23 is driven to move downward together by the first round rod 23. While the second elastic member 24 moves downward, it will drive the second round rod 26 to slide inside the inclined slot 29. Thus, through the cooperation between the second round rod 26 and the inclined slot 29, while the second elastic member 24 moves downward, it moves toward the direction of the rectangular block 21. Furthermore, while the second elastic member 24 drives the second round rod 26 to move, through the cooperation between the second round rod 26 and the straight slot of the clamping plate 27, the clamping plate 27 is driven to move in the same direction.

[0049] Since the orientations of the two inclined grooves 29 are opposite, when the two clamping plates 27 move, they will drive the two gaskets 28 to move towards each other and abut against both sides of the support beam body 4, thereby clamping and limiting the support beam body 4. Subsequently, since the gasket 28 is made of rubber material, the contact area and friction between the gasket 28 and the side wall of the support beam body 4 are increased. When there is a force that causes the support beam body 4 to slide along the surface of the steel bracket body 1, the friction force can effectively resist this sliding trend, achieving an anti-slip effect, thereby ensuring that the position of the support beam body 4 on the steel bracket body 1 remains fixed, and further ensuring the safety and reliability of the structure and improving the overall anti-slip performance of the device;

[0050] After the bottom of the support beam body 4 abuts against the top of the steel bracket body 1, at this time, the cross block 33 is inserted into the inner part of the second circular groove of the second card slot 5 through the cross groove. Subsequently, the operator pushes the push rod 34 upward, so that the push rod 34 moves upward under the vertical limit of the square groove 38, and further drives the connecting column to slide along the track of the arc groove 32. Since the push rod 34 can only drive the connecting column to move straight upward, through the cooperation between the connecting column and the arc groove 32, the rotating cylinder 31 drives the cross block 33 to rotate in the second circular groove. When the push rod 34 moves upward a certain distance, its outer wall will abut against the inclined surface at the bottom end of the inclined block 36, thereby squeezing the two inclined blocks 36 to move in opposite directions;

[0051] When the bottom end of the push rod 34 is completely inserted into the inner part of the first circular groove, at this time, the inclined block 36 will also reset under the elastic force of the third elastic member 37, so as to be inserted into the inner part of the first card slot 35 and fix the position of the push rod 34 after moving upward. At the same time, the connecting column of the push rod 34 also slides to the top end of the arc groove 32, so that the arc groove 32 drives the cross block 33 to rotate by 45 degrees, and then the rotated cross block 33 is misaligned with the track of the cross groove in the second card slot 5, so that the cross block 33 is stuck in the inner part of the support beam body 4 through the second card slot 5, thereby limiting the support beam body 4 in the vertical direction and improving the subsequent anti-slip effect.
