Combined anti-slip limiting device

Abstract

This invention discloses a combined anti-slip limiting device, comprising two buckle plates respectively disposed above and below a distribution beam. The buckle plates are U-shaped, and pairs of bolts and nuts are provided at the edges of the two buckle plates that are close to each other. The two buckle plates are fixed together by the bolts and nuts. An auxiliary fixing frame is fixedly connected to the upper surface of the buckle plates, and an auxiliary fixing component is disposed inside the auxiliary fixing frame. A bonding plate is disposed on the buckle plate, with one side of the bonding plate contacting the distribution beam. This invention, by buckling the two U-shaped buckle plates respectively to the upper and lower sides of the distribution beam, generates a clamping force through the tightening of the bolts and nuts, making the buckle plates and the distribution beam fit tightly together. The static friction between the two counteracts the longitudinal and lateral slippage forces of the distribution beam in longitudinal slope sections. At the same time, the bonding screw drives the bonding plate to press against the side wall of the distribution beam, which, together with the bidirectional clamping action of the auxiliary fixing component, forms a dual constraint of main fastening and auxiliary limiting, restricting the displacement of the distribution beam from multiple dimensions and completely solving the problem of distribution beam slippage in longitudinal slope sections.

Description

Technical Field

[0001] This application relates to the field of engineering construction technology, and in particular to a combined anti-slip limiting device. Background Technology

[0002] In the formwork system of cast-in-place beams, cast-in-place cap beams and other structures, the longitudinal and transverse steel distribution beams are important load-bearing structures and components of the support system of cast-in-place beams, cap beams and other bridge structures. In sections with large longitudinal slopes, if anti-slip measures are not taken, the longitudinal and transverse distribution beams will slip, causing changes in the spacing of the distribution beams, which will significantly alter the load-bearing system of the longitudinal and transverse distribution beams and have an uncontrollable impact on the stability of the formwork support system.

[0003] In the existing technology, the current limiting measures for longitudinal and transverse distribution beams mainly adopt spot welding or adding wedge blocks in the sliding direction. However, this method involves a large amount of welding work, and during dismantling, the welded points need to be cut or manually hammered to loosen the welded points and separate the longitudinal and transverse distribution beams, which is also a lot of work. Therefore, a combined anti-slip limiting device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a combined anti-slip limiting device to solve the problems mentioned in the background art.

[0005] The embodiments of this application adopt the following technical solutions:

[0006] A combined anti-slip limiting device includes two buckle plates respectively disposed above and below a distribution beam. The buckle plates are U-shaped. Pairs of bolts and nuts are provided at the edges of the two buckle plates that are close to each other. The two buckle plates are fixed to each other by bolts and nuts. An auxiliary fixing frame is fixedly connected to the upper surface of the buckle plates. An auxiliary fixing component is provided in the auxiliary fixing frame. A bonding plate is provided on the buckle plates. One side of the bonding plate is in contact with the distribution beam.

[0007] Preferably, the auxiliary fixing component includes an auxiliary fixing rod fixedly connected to the inner wall of the auxiliary fixing frame, an auxiliary bidirectional screw rotatably connected to the inner wall of the auxiliary fixing frame, and a knob rotatably connected to one side of the auxiliary fixing frame, the knob being coaxially fixed with the auxiliary bidirectional screw.

[0008] Preferably, the auxiliary fixing component further includes two auxiliary fixing plates that are slidably connected to the inner wall of the auxiliary fixing frame, both of which are slidably connected to the auxiliary fixing rod and threadedly connected to the auxiliary bidirectional screw.

[0009] Preferably, a limiting rod is fixedly connected to the side of the bonding plate away from the distribution beam, the limiting rod is slidably connected to the buckle plate, and a bonding screw is rotatably connected to the side of the bonding plate away from the distribution beam, the bonding screw being rotatably connected to the buckle plate.

[0010] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects:

[0011] Firstly, this invention involves symmetrically fastening the upper and lower U-shaped fasteners to the upper and lower sides of the distribution beam, and tightening the bolts and nuts to continuously clamp the fasteners to the distribution beam, ensuring a tight fit between the fasteners and the distribution beam. Simultaneously, rotating the fastening screw drives the fastening plate smoothly towards the side wall of the distribution beam, while the limiting rod slides synchronously to guide and prevent the fastening plate from deflecting, ensuring that the fastening plate tightly presses against the side wall of the distribution beam to form a lateral constraint. Then, rotating the knob drives the auxiliary bidirectional screw to rotate synchronously, driving the two auxiliary fixing plates to move synchronously towards each other along the auxiliary fixing rod, so that the auxiliary fixing plates clamp the distribution beam bidirectionally to form a top locking constraint, achieving multi-directional limiting and reducing the longitudinal slippage and lateral offset of the distribution beam.

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0019] Please see Figure 1-3 This invention provides a combined anti-slip limiting device technical solution:

[0020] A combined anti-slip limiting device includes two buckle plates 1 respectively disposed above and below a distribution beam. The buckle plates 1 are in the shape of a "Z". Pairs of bolts and nuts 2 are provided at the edges of the two buckle plates 1 that are close to each other. The two buckle plates 1 are fixed to each other by bolts and nuts 2. An auxiliary fixing frame 3 is fixedly connected to the upper surface of the buckle plate 1. An auxiliary fixing component is provided inside the auxiliary fixing frame 3. A bonding plate 4 is provided on the buckle plate 1. One side of the bonding plate 4 is in contact with the distribution beam.

[0021] Specifically, the buckle plate 1 is the core load-bearing and clamping component of the device. It is made of hot-rolled steel and has a symmetrical Z-shaped cross-section structure. The concave dimensions of the Z-shape match the outer contour of the standard steel distribution beam, ensuring that the buckle plate 1 fully fits the upper and lower surfaces and the root of the side of the distribution beam after being fastened, without gaps or looseness. The two buckle plates 1 are the upper buckle plate 1 and the lower buckle plate 1, which are symmetrically fastened to the top and bottom of the distribution beam. Symmetrical bolt holes are pre-drilled at the horizontal edges of the two buckle plates, and the spacing of the holes is evenly set according to the width of the distribution beam. Multiple pairs of bolt holes are provided on each side edge to ensure even distribution of fastening force. During installation, the bolts are passed through the upper and lower buckle plates 1. After the bolts are pierced and the nuts are tightened, the upper and lower buckle plates 1 will generate a continuous clamping force, making the inner wall of buckle plate 1 fit tightly against the surface of the distribution beam. The static friction between the two counteracts the longitudinal and lateral sliding forces of the distribution beam, thus achieving the main fastening constraint. The vertical side wall of buckle plate 1 is pre-drilled with a threaded hole for mounting the fitting screw 10 and a guide hole for the limiting rod 9. The threaded hole is a standard fine thread to ensure the stability of the fitting screw 10 when rotating. The guide hole for the limiting rod 9 is a smooth round hole with a diameter that matches the limiting rod 9, ensuring that the limiting rod 9 can slide freely without deflection. At the same time, the upper surface of buckle plate 1 and auxiliary fixing frame 3 are fully welded together, and the weld is treated with anti-corrosion and anti-rust treatment to ensure the connection strength.

[0022] In this embodiment, as Figure 3 As shown, the auxiliary fixing component includes an auxiliary fixing rod 5 fixedly connected to the inner wall of the auxiliary fixing frame 3. The auxiliary fixing frame 3 is made of channel steel welded together, and has an overall rectangular frame structure. It is fixedly installed at the center of the upper surface of the buckle plate 1, serving as the mounting carrier for the auxiliary fixing component. The inner wall of the frame is flat and smooth, providing guidance for the sliding of the auxiliary fixing plate 8. The auxiliary fixing rod 5 is made of high-precision round steel, and its two ends are welded and fixed to the left and right inner walls of the auxiliary fixing frame 3. It is horizontally set inside the auxiliary fixing frame 3, serving as a sliding guide rod for the auxiliary fixing plate 8, ensuring the straightness of the auxiliary fixing plate 8 during movement, and preventing skewing or jamming. An auxiliary bidirectional screw 6 is rotatably connected to the inner wall of the auxiliary fixing frame 3, and a knob 7 is rotatably connected to one side of the auxiliary fixing frame 3. The knob 7 is coaxially fixed with the auxiliary bidirectional screw 6.

[0023] The auxiliary fixing components also include two auxiliary fixing plates 8 that are slidably connected to the inner wall of the auxiliary fixing frame 3. Both auxiliary fixing plates 8 are slidably connected to the auxiliary fixing rod 5 and threadedly connected to the auxiliary bidirectional screw 6. The two auxiliary fixing plates 8 are symmetrically arranged on the left-hand threaded section and the right-hand threaded section of the auxiliary bidirectional screw 6. The main body of the fixing plate is made of steel plate to increase the friction when in contact with the distribution beam and improve the clamping and limiting effect. The bottom of the auxiliary fixing plate 8 has a smooth sliding hole that matches the auxiliary fixing rod 5. The sliding hole and the auxiliary fixing rod 5 are clearance-fitted to achieve a sliding connection. The middle of the fixing plate has a threaded hole that matches the auxiliary bidirectional screw 6 and is engaged with the left-hand thread and the right-hand thread, respectively. When the knob 7 drives the auxiliary bidirectional screw 6 to rotate, under the action of the left-hand and right-hand threads, the two auxiliary fixing plates 8 will move synchronously towards each other or backwards along the auxiliary fixing rod 5. When moving towards each other, they gradually clamp the side wall of the distribution beam to form a bidirectional clamping constraint. When moving backwards, they release the clamping and achieve quick disassembly.

[0024] In this embodiment, as Figure 2 As shown, a limiting rod 9 is fixedly connected to the side of the bonding plate 4 away from the distribution beam. The limiting rod 9 is slidably connected to the buckle plate 1. A bonding screw 10 is rotatably connected to the side of the bonding plate 4 away from the distribution beam. The bonding screw 10 is rotatably connected to the buckle plate 1. The bonding plate 4 is a lateral tightening component to ensure the support strength. Two limiting rods 9 are symmetrically welded to the side of the bonding plate 4 away from the distribution beam. The limiting rods 9 are made of round steel, and their length is set according to the thickness of the buckle plate 1 and the support stroke. The end of the limiting rod 9 away from the bonding plate 4 is inserted into the guide hole of the limiting rod 9 in the buckle plate 1 to form a sliding connection. The two limiting rods 9 are symmetrically distributed, which can effectively limit the rotation and deflection of the bonding plate 4 and ensure that the bonding plate 4 always remains perpendicular to the beam. The condition of the distribution beam sidewall is ensured to ensure that the tightening force is evenly applied to the distribution beam sidewall. The fitting screw 10 is a fine-pitch screw. One end is rotatably connected to the fitting plate 4 through a universal joint to prevent the fitting plate 4 from deflecting when the screw rotates. The other end extends through the threaded hole of the buckle plate 1 to the outside of the buckle plate 1 for easy rotation operation by construction personnel. When the fitting screw 10 is rotated, the screw generates axial displacement through thread transmission, pushing the fitting plate 4 to move towards the sidewall of the distribution beam until it is tightly pressed against the distribution beam, forming a lateral support constraint. Rotating the screw in the opposite direction will loosen the tightening. The tightening stroke can be freely adjusted according to the width of the distribution beam to adapt to different specifications of steel distribution beams. The tightening force is controllable and the operation is simple and convenient.

[0025] Working Principle: When using this combined anti-slip limiting device, the lower buckle plate 1 is lifted to the bottom of the distribution beam, so that the concave surface of the lower buckle plate 1 fits against the lower surface of the distribution beam. Then, the upper buckle plate 1 is fastened to the top of the distribution beam, so that the upper and lower buckle plates 1 are symmetrically aligned and the bolt holes correspond one-to-one. Then, high-strength bolts are passed through the bolt holes of the upper and lower buckle plates 1, nuts are put on, and wrenches are used to tighten them evenly. The tightening force of the bolts and nuts 2 creates a clamping force on the upper and lower buckle plates 1, and the inner wall of the Z-shaped buckle plate 1 fits tightly against the upper and lower surfaces of the distribution beam, completing the construction of the main fastening constraint. Then, the fitting screw 10 on the outside of the buckle plate 1 is rotated. Under the action of thread transmission, the fitting screw 10 is pushed towards the distribution beam, driving the fitting plate 4 to move smoothly. The limiting rod 9 slides synchronously in the guide hole to prevent the fitting plate 4 from deflecting. The screw is continuously rotated until the fitting plate 4 presses against the side wall of the distribution beam, and the lateral clamping force further tightens the clamp. The device restricts the lateral displacement of the distribution beam and simultaneously resists longitudinal slippage force, forming the first auxiliary limiting constraint. Rotating the knob 7 on the outside of the auxiliary fixing frame 3 drives the auxiliary bidirectional screw 6 to rotate synchronously. Under the action of the bidirectional screw, the two auxiliary fixing plates 8 move synchronously towards each other along the auxiliary fixing rod 5, gradually clamping the top sidewall of the distribution beam until the auxiliary fixing plates 8 are tightly attached to the surface of the distribution beam. Multi-dimensional limiting is achieved from the top through bidirectional clamping force, further strengthening the device's anti-slip effect and forming the second auxiliary limiting constraint. After construction, no destructive operations such as cutting or hammering are required. Simply rotate the knob 7 in the opposite direction to loosen the clamping of the auxiliary fixing plates 8; then rotate the attachment screw 10 in the opposite direction to detach the attachment plate 4 from the sidewall of the distribution beam; finally, loosen the bolts and nuts 2 and remove the upper and lower buckle plates 1 from the distribution beam. The device remains intact and can be directly transported to the next construction section for reuse.
