Description

Technical Field

[0001] The present application relates to the technical field of railings, and in particular to a high-stability railing. Background Art

[0002] As a type of safety facility, railings are widely used in rivers, bridges, dams, and municipal construction, playing a very important role in daily life. When fixing the railings, multiple steel bars are first welded to the lower surface of the steel plate. Concrete is poured into the locations where the steel bars and steel plate are located. After the concrete is formed, the steel plate and steel bars are pre-embedded. The steel bars are used to increase the strength of the connection between the steel plate and the concrete. The railings are then fixed to the upper surface of the steel plate. However, the contact area between the steel bars and the concrete is small, and the steel plate has weak pull-out resistance. When the railing is subjected to greater pressure, the stability of the steel plate may be affected, thereby affecting the stability of the railing, which needs to be improved. Summary of the Invention

[0003] In order to improve the stability of the railing, the present application provides a high-stability railing.

[0004] The high stability railing provided in this application adopts the following technical solution:

[0005] A high-stability railing includes a steel plate and a reinforcement portion for embedding in concrete. The reinforcement portion includes a reinforcement plate and an anti-pullout plate. The reinforcement plate is fixedly connected to the surface of the steel plate along its own thickness direction. The anti-pullout plate is fixedly connected to the reinforcement plate, and an angle exists between the anti-pullout plate and the reinforcement plate. The reinforcement plate is provided with a plurality of accommodating grooves for embedding concrete.

[0006] By adopting the above technical solution, when the steel plate and the reinforcement part are embedded in the concrete, the contact area with the concrete is increased by the reinforcement plate and the anti-pullout plate. At the same time, the concrete is embedded in the receiving groove. After the concrete is formed, the angle between the reinforcement plate and the anti-pullout plate and the wall of the receiving groove interact with the concrete, so that the concrete limits the movement of the reinforcement plate and the steel plate, thereby improving the stability of the steel plate and the railing.

[0007] Preferably, it also includes a pedal and an extrusion part for embedding in concrete, the extrusion part includes a sliding plate and a clamping plate, the sliding plate is slidably connected to the steel plate, the sliding plate and the reinforcing plate are located on the same side of the steel plate, and the sliding direction of the sliding plate is the same as the distribution direction of the sliding plate and the reinforcing plate, the clamping plate is fixedly connected to the sliding plate and forms an angle toward the reinforcing plate; the pedal is located on the side of the steel plate away from the sliding plate and is connected to the sliding plate, and the pedal is used to drive the sliding plate to slide.

[0008] By adopting this technical solution, it is difficult to achieve close contact between the concrete and the lower surface of the steel plate during concrete pouring, and air may be trapped in the concrete. However, by stepping on the pedal, the sliding plate slides toward the reinforcing plate. The reinforcing plate and sliding plate work together to squeeze the concrete, allowing the concrete to contact the steel plate surface as much as possible and squeezing out any trapped air. This results in a denser concrete after forming, improving the stability of the steel plate and railing. Furthermore, the angle formed between the clamping plate and the sliding plate allows the clamping plate to interact with the concrete after forming, improving the stability of the sliding plate, steel plate, and railing.

[0009] Preferably, the sliding plate is provided with air holes, and the air holes pass through the sliding plate.

[0010] By adopting the above technical solution, when the sliding plate slides, air mixed with the concrete and the air between the concrete and the steel plate can be discharged through the air holes, so that the concrete between the sliding plate and the reinforcing plate becomes denser as the sliding plate and the reinforcing plate are squeezed. The area after the sliding plate slides will automatically fill based on the fluidity of the concrete, so that the concrete can wrap around the sliding plate. After the concrete is formed, there will be concrete in the air holes, which will connect the concrete on both sides of the sliding plate, making the sliding plate more stably embedded in the concrete, thereby improving the stability of the steel plate and railing.

[0011] Preferably, it also includes a slider, the steel plate is provided with a slide groove, the slider is slidably embedded in the slide groove, the slider is fixedly connected to the sliding plate, the side of the slider facing away from the sliding plate is hinged to the pedal by setting a hinge shaft, the outer periphery of the hinge shaft is coaxially sleeved with a torsion spring, and the torsion spring abuts the slider and the pedal; the surface of the steel plate close to the pedal is provided with a plurality of slots, all of the slots are distributed along the sliding direction of the sliding plate, and the slot is located on one side of the slide groove, the slot is used for one end of the pedal to be embedded, and the slot wall of the slot is used to abut the pedal.

[0012] By adopting the above technical solution, the groove wall of the slide groove limits the sliding of the slider. By stepping on the pedal, the pedal rotates around the hinge axis and squeezes the torsion spring. When the pedal is out of the groove, the pedal drives the slider and the sliding plate to slide. When the pedal is not stepped on, the pedal is reset and embedded in the groove based on the elastic force of the torsion spring. The pedal is limited by the groove wall of the groove to minimize the sliding plate from sliding in the direction away from the reinforcing plate, so that the extruded concrete can remain dense and wait for molding, thereby improving the stability of the steel plate and the railing.

[0013] Preferably, a guide surface is provided on the groove wall of the clamping groove close to the chute, and the distance from the guide surface to the surface of the steel plate where the clamping groove is provided gradually decreases as it approaches the chute.

[0014] By adopting the above technical solution, when the pedal slides, one end of the pedal embedded in the card slot can gradually disengage from the card slot along the guide surface, without having to rotate the pedal to disengage from the card slot before sliding, thereby improving the sliding efficiency of the pedal and further improving the sliding efficiency of the sliding plate.

[0015] Preferably, a baffle is fixedly connected to the surface of the sliding plate close to the reinforcing plate, the baffle is slidably attached to the steel plate close to the surface of the steel plate, and the baffle is used to cover the slide groove.

[0016] By adopting the above technical solution, when pouring concrete, concrete is prevented from entering the chute and affecting the sliding of the slider, thereby improving the sliding efficiency of the sliding plate. At the same time, when the sliding plate slides, the sliding plate and the reinforcing plate are prevented from squeezing the concrete and causing it to flow out of the chute, thereby improving the efficiency of concrete pouring.

[0017] Preferably, a surface of the baffle close to the reinforcing plate is provided with an avoidance surface, and the distance from the avoidance surface to the steel plate gradually decreases as it approaches the reinforcing plate.

[0018] By adopting the above technical solution, when the sliding plate slides, the avoidance surface guides the concrete squeezed by the sliding plate and the reinforcing plate, facilitating the sliding of the baffle. At the same time, the concrete squeezed by the avoidance surface tends to move away from the steel plate, causing internal mixing of the concrete, thereby improving the density of the concrete.

[0019] Preferably, one end of the pedal away from the slot is hinged to a limit plate, and the end of the limit plate away from the pedal is used to abut against the ground.

[0020] By adopting the above technical solution, when the pedal is embedded in the slot, the limit plate abuts against the ground, and the limit plate limits the rotation of the pedal, thereby preventing the pedal from rotating out of the slot, thereby making the position of the sliding plate more stable, which is convenient for subsequent concrete forming.

[0021] Furthermore, since railings are often installed near rivers, where dangerous situations can occur, the end of the railing embedded in the slot can be used to quickly attach equipment such as a looped rope or hook, facilitating immediate river rescue. Specifically, by rotating the pedal and attaching the rope or hook, the torsion spring forces one end of the pedal to engage in the slot, where it abuts against the steel plate via a stopper plate, minimizing the rope or hook from detaching from the pedal. This improves safety and reduces the likelihood of potential danger.

[0022] Preferably, a friction pair is formed between the contact surface of the limiting plate and the pedal.

[0023] By adopting the above technical solution, when the limit plate rotates, the limit plate can be fixed in position due to the friction between the pedals unless people apply external force to the limit plate. When people step on the sliding pedal, the pedal can slide continuously, thereby improving the sliding efficiency of the pedal and the sliding plate.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Through the interaction between the angle between the reinforcing plate and the anti-pullout plate and the accommodating groove wall and the concrete, the concrete restricts the movement of the reinforcing plate and the steel plate, thereby improving the stability of the steel plate and the railing;

[0026] 2. The setting of the guide surface and the friction pair formed between the limit plate and the pedal enable the pedal to slide continuously, thereby improving the sliding efficiency of the pedal and the sliding plate;

[0027] 3. The setting of the limit plate: when an emergency occurs on the riverside, people can put the rope on the pedal for immediate rescue to improve people's safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] Reference Figure 1 The embodiment of the present application discloses a high-stability railing, comprising a steel plate 1, a reinforcement portion 2 and an extrusion portion 3. The reinforcement portion 2 comprises a reinforcement plate 21 and an anti-pullout plate 22. The reinforcement plate 21 is welded to the steel plate 1, and the reinforcement plate 21 is located on one side of the thickness direction of the steel plate 1, and the reinforcement plate 21 is perpendicular to the steel plate 1. The anti-pullout plate 22 is integrally formed at one end of the reinforcement plate 21 away from the steel plate 1, and the anti-pullout plate 22 is perpendicular to the reinforcement plate 21. The extrusion portion 3 comprises a sliding plate 31 and a clamping plate 32. The sliding plate 31 is arranged parallel to the reinforcement plate 21, and the sliding plate 31 and the reinforcement plate 21 are located on the same side of the steel plate 1.

[0035] Reference Figure 2 and Figure 3 The steel plate 1 is provided with three chutes 11 on its surface along its thickness direction. The chutes 11 penetrate the steel plate 1 along its thickness direction, and the length direction of the chutes 11 is perpendicular to the sliding plate 31. The surface of the sliding plate 31 close to the steel plate 1 is integrally formed with three sliders 320, and the three sliders 320 are respectively slidably embedded in the three chutes 11. The surface of the sliding plate 31 close to the reinforcing plate 21 is fixedly connected with three baffles 33. The surface of the baffle 33 close to the steel plate 1 is used to slide and fit the steel plate 1, and the three baffles 33 respectively cover the three chutes 11 to prevent concrete from flowing into the chutes 11 as much as possible. The surface of the baffle 33 close to the reinforcing plate 21 is provided with an avoidance surface 331, and the distance from the avoidance surface 331 to the steel plate 1 gradually decreases as it approaches the reinforcing plate 21.

[0036] Reference Figure 3 The clipping plate 32 is integrally formed on the surface of the sliding plate 31 facing away from the steel plate 1. The clipping plate 32 is perpendicular to the sliding plate 31, and the surfaces facing away from the clipping plate 32 and the anti-pullout plate 22 are respectively flush with the surfaces facing away from the sliding plate 31 and the reinforcing plate 21. The sliding plate 31 is provided with a plurality of air holes 311. The air holes 311 penetrate the sliding plate 31 along the thickness direction of the sliding plate 31, and the air holes 311 are close to the steel plate 1 to facilitate the discharge of air between the concrete and the steel plate 1, thereby making the concrete more dense. The sliding plate 31 is provided with receiving grooves 312 on both surfaces along its own thickness direction, and the projections of the receiving grooves 312 on both sides of the sliding plate 31 in the thickness direction of the sliding plate 31 do not overlap along the thickness direction of the sliding plate 31. The two surfaces of the reinforcing plate 21 along its own thickness direction are also provided with multiple receiving grooves 312. The projections of the receiving grooves 312 on both sides of the thickness direction of the reinforcing plate 21 along the thickness direction of the reinforcing plate 21 do not overlap. The receiving grooves 312 are used for concrete to flow into. When the concrete is solidified and formed, the interaction force between the sliding plate 31, the reinforcing plate 21 and the concrete is increased, thereby improving the stability of the steel plate 1 and thus improving the stability of the railing.

[0037] Reference Figure 1 and Figure 2A high-stability handrail further includes a pedal 4, a slider 320 extending out of the slide slot 11 in a direction away from the sliding plate 31, and a first hinge slot 321 is provided at one end of the slider 320 facing away from the sliding plate 31. A first hinge block 41 is integrally formed on the lower surface of the pedal 4, and the first hinge block 41 is embedded in the first hinge slot 321. A rotation slot 411 is provided on the surface of the first hinge block 41 facing away from the pedal 4. The first hinge block 41 and the slider 320 are both provided with a hinge hole 322, and the hinge hole 322 of the first hinge block 41 and the hinge hole 322 of the slider 320 are coaxial. The hinge hole 322 axially penetrates the first hinge block 41 and the slider 320, and a hinge shaft 323 is embedded in the hinge hole 322. A torsion spring 324 is coaxially sleeved on the outer circumference of the hinge shaft 323, and the torsion spring 324 is located in the rotation slot 411. The two ends of the torsion spring 324 respectively abut the slider 320 and the pedal 4.

[0038] Reference Figure 2 and Figure 4 The surface of the steel plate 1 near the pedal 4 is provided with a plurality of slots 12. The slots 12 extend through the steel plate 1 along the axial direction of the hinge shaft 323. The distribution direction of all the slots 12 is the same as the sliding direction of the sliding plate 31. The slots 12 are located on the side of the chute 11 away from the reinforcing plate 21. A guide surface 13 is provided on the wall of the chute near the chute 11. The distance from any point on the guide surface 13 to the surface of the steel plate 1 having the slots 12 gradually decreases as the point approaches the chute 11.

[0039] By stepping on the pedal 4, the pedal 4 drives the slider 320 and the sliding plate 31 to slide along the slide groove 11, thereby causing the reinforcing plate 21 and the sliding plate 31 to squeeze the concrete, making the concrete more dense. After the concrete solidifies, the connection strength between the concrete and the reinforcing plate 21 and the sliding plate 31 is improved, thereby improving the stability of the railing. The torsion spring 324 ensures that one end of the pedal 4 is stably embedded in the slot 12, thereby minimizing the sliding plate 31 from sliding away from the reinforcing plate 21.

[0040] The end of the pedal 4 away from the slot 12 is hingedly connected to two limit plates 5. Specifically, the end of the pedal 4 away from the slot 12 is provided with two connecting slots 42. One end of the limit plate 5 is embedded in the connecting slot 42, and the groove walls of the limit plate 5 and the connecting slot 42 are both provided with connecting holes 43. The connecting holes 43 provided on the limit plate 5 and the connecting holes 43 provided on the groove walls of the connecting slot 42 are coaxial, and the axis of the connecting hole 43 is parallel to the axis of the hinge hole 322. The connecting hole 43 axially passes through the limit plate 5 and the pedal 4. A connecting shaft 44 is coaxially embedded in the connecting hole 43. The end of the limit plate 5 away from the connecting slot 42 is used to abut the steel plate 1. When the limit plate 5 abuts the steel plate 1, it limits the rotation of the pedal 4, thereby limiting the sliding of the pedal 4. When the pedal 4 needs to be slid, the limit plate 5 is rotated so that the limit plate 5 is separated from the steel plate 1, thereby enabling the rotation of the pedal 4. A friction pair is formed between the contact surfaces of the pedal 4 and the limit plate 5, so that after the limit plate 5 rotates, the limit plate 5 can maintain a relatively static state with the pedal 4 based on friction, reducing the probability of the limit plate 5 rotating to abut the steel plate 1 due to its own gravity, so as to facilitate the sliding of the pedal 4.

[0041] Reference Figure 2 and Figure 3 Among the three sliders 320, the surfaces of the two sliders 320 located on the outside are welded with positioning plates 325 that are facing away from each other, and the positioning plates 325 slide against the surface of the steel plate 1 close to the steel plate 1, while the baffle 33 slides against the surface of the steel plate 1 facing away from the pedal 4, so as to improve the stability of the pedal 4 driving the sliders 320 and the sliding plate 31 to slide.

[0042] Reference Figure 4 The surface of the pedal 4 facing away from the steel plate 1 is fixed with an anti-slip strip 6 to facilitate people stepping on the pedal 4, thereby facilitating people driving the pedal 4 to drive the sliding plate 31. The end of the pedal 4 that is inserted into the slot 12 is provided with a plurality of equally spaced tooth grooves 15, with serrations 14 formed between adjacent tooth grooves 15. The serrations 14 are used to loop a rope. When the pedal 4 rotates to disengage the serrations 14 from the slot 12, the rope can be looped around the serrations 14. Then, by rotating the limit plate 5 until it abuts the steel plate 1, the rope is stable when looped around the serrations 14.

[0043] Reference Figure 1 A high-stability railing also includes a railing body 7, which includes a longitudinal rod 71 and a transverse tube 72. The lower end of the longitudinal rod 71 is fixedly connected to the upper surface of the steel plate 1, and the outer periphery of the transverse tube 72 is fixedly connected to the upper end of the longitudinal rod 71. When people lean on the longitudinal rod 71 or the transverse tube 72, the stability of the steel plate 1 buried in the concrete is improved, thereby improving the stability of the railing body 7.

[0044] The implementation principle of a high-stability handrail according to an embodiment of the present application is as follows: by stepping on the pedal 4, the pedal 4 rotates about the hinge shaft 323 and compresses the torsion spring 324. The pedal 4 then drives the slider 320 and the sliding plate 31 to slide, and the sliding plate 31 and the reinforcing plate 21 jointly squeeze the concrete. Furthermore, the sliding plate 31 is provided with a plurality of air holes 311 near the steel plate 1. When the sliding plate 31 and the reinforcing plate 21 squeeze the concrete, air between the concrete and the steel plate 1 is easily expelled, thereby making the concrete more dense and improving the connection strength between the concrete and the reinforcing plate 21 and the sliding plate 31 after solidification. When the user stops stepping on the pedal 4, one end of the pedal 4 is embedded in the slot 12 due to the elastic force of the torsion spring 324, preventing the sliding plate 31 from sliding in a direction away from the reinforcing plate 21.

[0045] One end of the pedal 4 is inserted into the slot 12 for looping a rope. When the pedal 4 is rotated until the rope can be looped around the serrations 14, the stop plate 5 abuts the steel plate 1 to prevent the pedal 4 from rotating as much as possible, thereby improving the stability of the rope when looping around the pedal 4. When people are working near the river, they can quickly loop the rope around the serrations 14, thereby improving work efficiency.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
