Description

Technical Field

[0001] This invention belongs to the field of traffic engineering technology, specifically a rapid assembly walkway slab device and its construction method. Background Technology

[0002] As the name suggests, a walkway is a structural panel for people to walk on. Walkways have a wide range of applications and come in many varieties. In the event of natural disasters such as mudslides and floods, rescue teams urgently need to cross rivers to provide support to the other side, requiring the temporary construction of bridge-like walkways for rapid river crossing.

[0003] Chinese patent CN111379409A discloses a walkway slab, which is a single piece formed using a cold-bending process. The walkway slab has an inverted U-shaped cross-section and consists of a wave-shaped panel formed by rolling two anti-bending grooves, bow-shaped side panels formed by bending the sides of the panel downwards, and wave-shaped end panels formed by bending the ends of the panel downwards. This device abandons traditional production processes, employing a cold-bending process to reduce the cumbersome steps of traditional production, making the production and processing of building climbing scaffold walkway slabs extremely simple and significantly reducing costs.

[0004] In the current technology, when encountering natural disasters such as mudslides and floods, rescue teams urgently need to cross rivers to provide support to the other side. Temporary floating bridge-like walkways need to be built to quickly cross the river. The existing walkways are complicated and cumbersome to assemble, and the construction period is long, which seriously affects the rescue mission.

[0005] Therefore, the present invention provides a rapid assembly walkway slab device and its construction method. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A quick-assembly walkway device of this invention includes a set of pedals; an air-floating body is fixedly connected to the underside of each pedal; connecting plates are fixedly connected to both sides of each pedal; a pin is fixedly connected to the surface of the connecting plate on one side of each pedal, and a pin hole is opened on the surface of the connecting plate on the other side of each pedal, with the pin engaging with the pin hole; multiple pedals can be interconnected through connecting plates, pins, and pin holes; in the prior art, when encountering natural disasters such as mudslides and floods, rescue teams urgently need to cross rivers to the other side, requiring the temporary construction of floating bridge-type walkways for rapid river crossing. The existing walkway assembly process is relatively complex and cumbersome. The construction process is cumbersome and time-consuming, severely impacting rescue missions. This invention addresses this by incorporating multiple treads and air-floating bodies. When temporary floating bridge walkways are needed, the appropriate number of treads and air-floating bodies can be selected based on the river's width. Multiple treads are then arranged sequentially on the ground, with connecting plates between adjacent treads brought close together so that pins are aligned with their holes and inserted. After connecting multiple treads, a walkway is formed. This walkway is then placed on the river surface, buoyed by the air-floating bodies, and its ends are fixed to the riverbank, creating a temporary floating bridge walkway for personnel passage. This improves the assembly efficiency of the walkway and shortens the construction period.

[0008] Preferably, a groove is provided on one side of the pin; a slider is slidably connected inside the groove, and the portion of the slider protruding from the groove has an inclined surface; a spring is fixedly connected between the slider and the blind end of the groove; when the connecting plates between adjacent pedals are brought close together, the pin is aligned with the pin hole and inserted. During the insertion process, the inclined surface of the slider is squeezed by the connecting plate, causing the slider to retract into the groove. After the pin is fully inserted into the pin hole, the slider is pushed out by the spring and locks the pin inside the pin hole, improving the connection stability between the pedals.

[0009] Preferably, a set of circular grooves are evenly distributed on the upper surface of the pedal; a through hole is opened at the bottom of the circular groove, and the through hole passes through the pedal; an anti-slip ball is provided inside the circular groove, and a set of elastic sheets are evenly distributed on the surface of the anti-slip ball; by setting anti-slip balls and elastic sheets on the surface of the pedal, the anti-slip effect of the pedal can be improved, reducing the problem of people accidentally slipping when passing through the walkway. At the same time, when people step on the surface of the anti-slip ball, the elastic sheets can scrape off the mud on the surface of the shoe sole, and the scraped mud can fall into the circular groove through the surface of the anti-slip ball, and finally fall through the through hole.

[0010] Preferably, the sidewall of the circular groove has an oblong groove; a connecting rod is slidably connected inside the oblong groove, and a spring is fixed between the connecting rod and the bottom of the oblong groove; the connecting rod passes through the anti-slip ball and is rotatably connected to it, and a torsion spring is installed between the connecting rod and the anti-slip ball; an inclined guide block is fixedly connected to the bottom of the anti-slip ball; a guide rod is fixed inside the through hole through a bracket, and the guide rod is in contact with the inclined surface of the inclined guide block; when a person steps on the anti-slip ball, it will push the anti-slip ball downward, and cause the connecting rod to slide downward inside the oblong groove. When the anti-slip ball moves downward, the inclined surface of the inclined guide block and the guide rod squeeze each other, thereby causing the anti-slip ball to rotate slightly, so that the elastic sheet scrapes on the surface of the shoe sole, further improving the efficiency of scraping mud.

[0011] Preferably, the air flotation body is configured as an elastic bladder structure, and a reaction ball is fixedly attached inside the air flotation body; the reaction ball has a liquid storage chamber and a material storage chamber inside, and the liquid storage chamber and the material storage chamber are separated by a sealing membrane; a dilute hydrochloric acid solution is added inside the liquid storage chamber, and calcium carbonate particles are added inside the material storage chamber; air guide holes are opened on the side wall surface of the material storage chamber; by configuring the air flotation body as an elastic bladder structure, the air flotation body is in a shrunken state when not in use, which can save space and reduce transportation costs. When it is needed, the sealing membrane can be punctured, and then the dilute hydrochloric acid solution inside the liquid storage chamber enters the material storage chamber, mixes with the calcium carbonate particles, and reacts to generate gas. The generated gas then enters the air flotation body through the air guide holes, thereby achieving the effect of inflating the air flotation body.

[0012] Preferably, the reaction ball is located at the bottom of the air flotation body, and the bottom of the reaction ball has an opening and a grid plate is fixedly connected to it; a sliding tube is fixedly connected to the upper side of the grid plate, and the sliding tube extends into the storage chamber; a movable block is slidably connected inside the sliding tube; a multi-faceted pin is fixedly connected to the upper side of the movable block, and an expansion strip is fixedly connected between the lower side of the movable block and the grid plate, and the expansion strip is made of water-absorbing material; after the multiple pedals are assembled to form a floating bridge-type walkway, the walkway can be placed directly on the water surface, and then the water comes into contact with the expansion strip through the grid plate. After the expansion strip absorbs water, it expands and elongates, pushing the movable block and the multi-faceted pin to move upward, and then the multi-faceted pin automatically punctures the sealing membrane. This operation makes the reaction process unnecessary for human intervention. As long as it is placed on the water surface, the air flotation body will automatically inflate, which improves the convenience of the walkway and further shortens the construction period.

[0013] Preferably, a flexible block is provided on the outside of the air guide hole; a pair of elastic ropes are fixed between the flexible block and the inner wall of the reaction ball, and the flexible block is close to the surface of the air guide hole; by setting the flexible block and elastic ropes, under normal circumstances the elastic ropes will tighten the flexible block and make the flexible block block the air guide hole, so as to avoid the problem of large shaking during transportation, which would cause the calcium carbonate particles inside the storage cavity to spill out through the air guide hole, thereby improving the utilization rate of calcium carbonate particles.

[0014] Preferably, a spiral groove is formed on the inner wall surface of the slide tube; a protrusion is fixedly connected to the side of the movable block, and the protrusion cooperates with the spiral groove; by setting the spiral groove and the protrusion, during the process of the expansion strip pushing the movable block to move upward, due to the cooperation between the protrusion and the spiral groove, the movable block will rotate synchronously while moving upward, thereby driving the multi-faceted pin to rotate, so that when the multi-faceted pin punctures the sealing film, it can tear the opening larger, thereby accelerating the flow of dilute hydrochloric acid solution and ensuring that the dilute hydrochloric acid solution can fall completely, thus improving the utilization rate of dilute hydrochloric acid solution.

[0015] Preferably, a first magnetic block is fixedly attached to the free end of the elastic sheet near the anti-slip ball; a second magnetic block is fixedly attached to the surface of the anti-slip ball near the first magnetic block, and the first and second magnetic blocks repel each other when they are close to each other; by setting the first and second magnetic blocks, when a person steps on the surface of the anti-slip ball, the elastic sheet will be squeezed and deformed, and then the first and second magnetic blocks will approach and contact each other. When the person lifts their foot, the elastic sheet will automatically rebound, and due to the repulsive effect between the first and second magnetic blocks, the rebound force of the elastic sheet will be increased, thereby causing the elastic sheet to shake violently, shaking off the dirt remaining on its surface, and improving the self-cleaning effect of the elastic sheet.

[0016] A construction method for a rapid assembly walkway slab device, the method employing the aforementioned rapid assembly walkway slab device, includes the following steps:

[0017] S1: Select an appropriate number of treads and air-floating bodies according to the width of the river, and then arrange multiple treads on the ground in sequence;

[0018] S2: Bring the connecting plates between adjacent pedals closer together so that the pin is aligned with the pin hole and inserted. During the insertion process, the inclined surface of the slider is squeezed by the connecting plate, and the slider retracts into the groove. After the pin is fully inserted into the pin hole, the slider pops out under the push of the spring and locks the pin inside the pin hole.

[0019] S3: After connecting multiple treads in sequence, a walkway slab can be formed as a whole. The walkway slab is then placed on the river surface, where it is buoyed by the air-floating body. Both ends of the walkway slab are fixed to the riverbank to form a temporary floating bridge for people to pass through.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. The present invention discloses a rapid assembly walkway device and its construction method. By setting up multiple treads and air-floating bodies, when a temporary floating bridge-type walkway needs to be built, an appropriate number of treads and air-floating bodies can be selected according to the width of the river. Then, multiple treads are arranged sequentially on the ground, and the connecting plates between adjacent treads are brought close together so that the pins are aligned with the pin holes and inserted. After the connection between multiple treads is completed in sequence, a walkway can be formed as a whole. Then, the walkway is placed on the river surface, and the air-floating bodies provide buoyancy. The two ends of the walkway are fixed to the riverbank to form a temporary floating bridge walkway for personnel passage. This improves the assembly efficiency of the walkway and shortens the construction period.

[0022] 2. The quick-assembly walkway slab device and its construction method of the present invention bring the connecting plates between adjacent slabs close to each other so that the pins are aligned with the pin holes and inserted. During the insertion process, the inclined surface of the slider is squeezed by the connecting plate, and the slider retracts into the groove. After the pin is fully inserted into the pin hole, the slider pops out under the push of the spring and locks the pin in the pin hole, thereby improving the connection stability between the slabs.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1

[0034] like Figures 1 to 5 As shown in the embodiment of the present invention, a rapid assembly walkway device includes a set of pedals 1; an air-floating body 2 is fixedly connected to the lower side of the pedal 1; connecting plates 3 are fixedly connected to both sides of the pedal 1; a pin 4 is fixedly connected to the surface of the connecting plate 3 on one side of the pedal 1, and a pin hole 5 is opened on the surface of the connecting plate 3 on the other side of the pedal 1, and the pin 4 cooperates with the pin hole 5; multiple pedals 1 can be connected to each other through the connecting plates 3, pins 4 and pin holes 5; in the prior art, when encountering natural disasters such as mudslides and floods, rescue teams urgently need to cross rivers to the other side to provide support, and temporary floating bridge-type walkways need to be built for rapid river crossing. The existing walkway assembly process is relatively complex and cumbersome. The long construction period severely impacted rescue operations. This invention addresses this by setting up multiple footboards 1 and air-floating bodies 2. When temporary floating bridge walkways are needed, an appropriate number of footboards 1 and air-floating bodies 2 can be selected based on the river's width. Multiple footboards 1 are then arranged sequentially on the ground, and connecting plates 3 between adjacent footboards 1 are brought close together so that pins 4 are aligned with nail holes 5 and inserted. After connecting multiple footboards 1 sequentially, a walkway is formed as a whole. The walkway is then placed on the river surface, buoyed by the air-floating bodies 2, and both ends of the walkway are fixed to the riverbank, forming a temporary floating bridge walkway for personnel passage. This improves the assembly efficiency of the walkway and shortens the construction period.

[0035] A groove 6 is provided on one side of the pin 4; a slider 7 is slidably connected inside the groove 6, and the part of the slider 7 protruding from the groove 6 has an inclined surface; a spring is fixed between the slider 7 and the blind end of the groove 6; when the connecting plates 3 between adjacent pedals 1 are brought close to each other, the pin 4 is aligned with the pin hole 5 and inserted. During the insertion process, the inclined surface of the slider 7 is squeezed by the connecting plate 3, and the slider 7 retracts into the groove 6. After the pin 4 is fully inserted into the pin hole 5, the slider 7 pops out under the push of the spring and locks the pin 4 into the pin hole 5, thereby improving the connection stability between the pedals 1.

[0036] A set of circular grooves 8 are evenly distributed on the upper surface of the pedal 1; a through hole 9 is provided at the bottom of the circular groove 8 and passes through the pedal 1; an anti-slip ball 10 is provided inside the circular groove 8, and a set of elastic sheets 11 are evenly distributed on the surface of the anti-slip ball 10; by setting the anti-slip ball 10 and elastic sheets 11 on the surface of the pedal 1, the anti-slip effect of the pedal 1 can be improved, reducing the problem of people accidentally slipping when passing through the walkway. At the same time, when people step on the surface of the anti-slip ball 10, the elastic sheets 11 can scrape off the mud on the surface of the shoe sole, and the scraped mud can fall into the circular groove 8 through the surface of the anti-slip ball 10 and finally fall through the through hole 9.

[0037] The circular groove 8 has a waist-shaped groove 12 on its side wall surface; a connecting rod 13 is slidably connected inside the waist-shaped groove 12, and a spring is fixed between the connecting rod 13 and the bottom of the waist-shaped groove 12; the connecting rod 13 passes through the anti-slip ball 10 and is rotatably connected to it, and a torsion spring is installed between the connecting rod 13 and the anti-slip ball 10; an inclined guide block 14 is fixedly connected to the bottom of the anti-slip ball 10; a guide rod 15 is fixedly connected inside the through hole 9 through a bracket, and the guide rod 15 is in contact with the inclined surface of the inclined guide block 14; when a person steps on the anti-slip ball 10, it will push the anti-slip ball 10 downward, and cause the connecting rod 13 to slide downward inside the waist-shaped groove 12. When the anti-slip ball 10 moves downward, the inclined surface of the inclined guide block 14 and the guide rod 15 squeeze each other, thereby causing the anti-slip ball 10 to rotate slightly, so that the elastic sheet 11 scrapes on the surface of the shoe sole, further improving the efficiency of scraping mud.

[0038] The air flotation body 2 is configured as an elastic bladder structure, and a reaction ball 16 is fixedly attached inside the air flotation body 2. The reaction ball 16 has a liquid storage chamber 17 and a material storage chamber 18 inside, and the liquid storage chamber 17 and the material storage chamber 18 are separated by a sealing membrane 19. The liquid storage chamber 17 is filled with dilute hydrochloric acid solution, and the material storage chamber 18 is filled with calcium carbonate particles. The side wall surface of the material storage chamber 18 is provided with a gas guide hole 20. By configuring the air flotation body 2 as an elastic bladder structure, the air flotation body 2 is in a shrunken state when not in use, which can save space and reduce transportation costs. When it is needed, the sealing membrane 19 can be punctured, and then the dilute hydrochloric acid solution inside the liquid storage chamber 17 enters the material storage chamber 18, mixes with the calcium carbonate particles and reacts to generate gas. The generated gas then enters the air flotation body 2 through the gas guide hole 20, thereby achieving the effect of inflating the air flotation body 2.

[0039] The reaction ball 16 is located at the bottom of the air flotation body 2, and the bottom of the reaction ball 16 has an opening and is fixedly connected to a grid plate 21; a sliding tube 22 is fixedly connected to the upper side of the grid plate 21, and the sliding tube 22 extends into the storage chamber 18; a movable block 23 is slidably connected inside the sliding tube 22; a multi-faceted pin 24 is fixedly connected to the upper side of the movable block 23, and an expansion strip 25 is fixedly connected between the lower side of the movable block 23 and the grid plate 21, and the expansion strip 25 is made of water-absorbing material; after the multiple pedals 1 are assembled and form a floating bridge-type walkway, the walkway can be placed directly on the water surface, and then the water comes into contact with the expansion strip 25 through the grid plate 21. After the expansion strip 25 absorbs water, it expands and elongates, pushing the movable block 23 and the multi-faceted pin 24 to move upward, and then the multi-faceted pin 24 automatically punctures the sealing membrane 19. This operation makes the reaction process do not require human intervention. As long as it is placed on the water surface, the air flotation body 2 will automatically inflate, which improves the convenience of the walkway and further shortens the construction period.

[0040] A flexible block 26 is provided on the outside of the air guide hole 20; a pair of elastic ropes 27 are fixed between the flexible block 26 and the inner wall of the reaction ball 16, and the flexible block 26 is close to the surface of the air guide hole 20; by setting the flexible block 26 and the elastic ropes 27, under normal circumstances the elastic ropes 27 will tighten the flexible block 26 and make the flexible block 26 block the air guide hole 20, so as to avoid the problem that the calcium carbonate particles inside the storage cavity 18 will spill out through the air guide hole 20 due to large shaking during transportation, thereby improving the utilization rate of calcium carbonate particles.

[0041] The inner wall surface of the slide tube 22 is provided with a spiral groove 28; the movable block 23 is fixedly connected to a protrusion 29 on its side, and the protrusion 29 cooperates with the spiral groove 28; by setting the spiral groove 28 and the protrusion 29, when the expansion strip 25 pushes the movable block 23 to move upward, due to the cooperation between the protrusion 29 and the spiral groove 28, the movable block 23 will rotate synchronously while moving upward, thereby driving the polygonal pin 24 to rotate, so that when the polygonal pin 24 punctures the sealing film 19, it can tear the opening larger, thereby accelerating the flow of dilute hydrochloric acid solution and ensuring that the dilute hydrochloric acid solution can fall completely, thus improving the utilization rate of dilute hydrochloric acid solution.

[0042] Example 2

[0043] like Figure 6As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a first magnetic block 30 is fixedly attached to the free end of the elastic sheet 11 near the anti-slip ball 10; a second magnetic block 31 is fixedly attached to the surface of the anti-slip ball 10 near the first magnetic block 30, and the first magnetic block 30 and the second magnetic block 31 can repel each other when they are close to each other; by setting the first magnetic block 30 and the second magnetic block 31, when a person steps on the surface of the anti-slip ball 10, the elastic sheet 11 will be squeezed and deformed, and then the first magnetic block 30 and the second magnetic block 31 will approach and contact each other. When the person lifts his foot, the elastic sheet 11 will automatically rebound, and due to the repulsive effect between the first magnetic block 30 and the second magnetic block 31, the rebound force of the elastic sheet 11 will be increased, thereby causing the elastic sheet 11 to shake violently, shaking off the dirt remaining on its surface, and improving the self-cleaning effect of the elastic sheet 11.

[0044] like Figure 7 As shown, a construction method for a rapid assembly walkway slab device is described. This method utilizes the aforementioned rapid assembly walkway slab device and includes the following steps:

[0045] S1: Select an appropriate number of pedals 1 and air-floating bodies 2 according to the width of the river, and then arrange multiple pedals 1 in sequence on the ground;

[0046] S2: Bring the connecting plates 3 between adjacent pedals 1 closer together so that the pin 4 is aligned with the pin hole 5 and inserted. During the insertion process, the inclined surface of the slider 7 is squeezed by the connecting plate 3, and the slider 7 retracts into the slide groove 6. After the pin 4 is fully inserted into the pin hole 5, the slider 7 pops out under the push of the spring and locks the pin 4 into the pin hole 5.

[0047] S3: After connecting multiple pedals 1 in sequence, the walkway slab can be formed as a whole. The walkway slab is then placed on the river surface, where it is buoyed by the air-floating body 2. The two ends of the walkway slab are fixed to the riverbank to form a temporary floating bridge for people to pass through.

[0048] Working Principle: This invention, by setting up multiple treads 1 and air-floating bodies 2, allows for the temporary construction of a floating bridge-like walkway. The appropriate number of treads 1 and air-floating bodies 2 can be selected based on the width of the river. Multiple treads 1 are then arranged sequentially on the ground. Connecting plates 3 between adjacent treads 1 are brought close together, aligning pins 4 with nail holes 5 and inserting them. After connecting multiple treads 1, a walkway is formed. The walkway is then placed on the river surface, where the air-floating bodies 2 provide buoyancy. Both ends of the walkway are fixed to the riverbank, forming a temporary floating bridge walkway for pedestrian access. This improves the assembly efficiency of the walkway and shortens the construction period. The connecting plates 3 between adjacent treads 1 are brought close together, aligning pins 4 with nail holes 5 and inserting them. During the process, the inclined surface of slider 7 is squeezed by connecting plate 3, causing slider 7 to retract into the groove 6. After pin 4 is fully inserted into pin hole 5, slider 7 is pushed out by spring and locks pin 4 into pin hole 5, improving the connection stability between pedals 1. By setting anti-slip ball 10 and elastic plate 11 on the surface of pedal 1, the anti-slip effect of pedal 1 can be improved, reducing the problem of people accidentally slipping when passing through the walkway. At the same time, when people step on the surface of anti-slip ball 10, elastic plate 11 can scrape off the mud on the sole of the shoe, and the scraped mud can fall into the circular groove 8 through the surface of anti-slip ball 10 and finally fall through through hole 9. When people step on anti-slip ball 10, it will push anti-slip ball 10 downward and cause connecting rod 13 to move in the waist-shaped groove 1. 2. As the anti-slip ball 10 slides downwards, the inclined surface of the inclined guide block 14 and the guide rod 15 press against each other, thereby causing the anti-slip ball 10 to rotate slightly, making the elastic sheet 11 scrape on the sole surface, further improving the efficiency of removing mud; by setting the air flotation body 2 as an elastic bladder structure, the air flotation body 2 is in a shrunken state when not in use, which can save space and reduce transportation costs. When needed, the sealing film 19 can be punctured, and the dilute hydrochloric acid solution inside the liquid storage chamber 17 can enter the material storage chamber 18, mix with the calcium carbonate particles and react to generate gas. The generated gas then enters the air flotation body 2 through the air guide hole 20, achieving the effect of inflating the air flotation body 2; after the multiple pedals 1 are assembled and form a floating bridge-type walkway, it can be directly The walkway slab is then placed on the water surface, and the water comes into contact with the expansion strip 25 through the grid plate 21. After absorbing water, the expansion strip 25 expands and elongates, pushing the movable block 23 and the multi-faceted pin 24 upward. The multi-faceted pin 24 then automatically punctures the sealing membrane 19. This operation eliminates the need for human intervention in the reaction process. As long as the air flotation body 2 is placed on the water surface, it will automatically inflate, improving the convenience of the walkway slab and further shortening the construction period. By setting up the flexible block 26 and the elastic rope 27, under normal circumstances, the elastic rope 27 will tighten the flexible block 26 and make the flexible block 26 block the air guide hole 20, avoiding the problem of large shaking during transportation, which would cause the calcium carbonate particles inside the storage chamber 18 to spill out through the air guide hole 20, thus improving the utilization rate of calcium carbonate particles.By setting the spiral groove 28 and the protrusion 29, during the process of the expansion strip 25 pushing the movable block 23 upward, the movable block 23 rotates synchronously as it moves upward due to the cooperation between the protrusion 29 and the spiral groove 28. This, in turn, drives the polygonal ejector pin 24 to rotate, allowing the polygonal ejector pin 24 to tear the sealing membrane 19 more thoroughly, thereby accelerating the flow of dilute hydrochloric acid solution and ensuring that the solution falls completely, thus improving the utilization rate of the solution. By setting the first magnetic block 30 and the second magnetic block 31, when a person steps on the surface of the anti-slip ball 10, the elastic sheet 11 will be squeezed and deformed. The first magnetic block 30 and the second magnetic block 31 will then approach and contact each other. When the person lifts their foot, the elastic sheet 11 automatically rebounds. Due to the repulsive effect between the first magnetic block 30 and the second magnetic block 31, the rebound force of the elastic sheet 11 is increased, causing it to vibrate violently and shake off residual dirt, thus improving the self-cleaning effect of the elastic sheet 11.
