Description

Technical Field

[0001] The invention belongs to the field of temporary construction facilities at a construction site, and in particular relates to a standardized temporary steel staircase. Background Art

[0002] Steel stairs are composed of staircases and railings and are used in construction. At present, the traditional stair entrances and stair edge guardrails of safety guardrail connectors are made of steel bar welded guardrails, or steel pipes and various fasteners, which cannot meet the requirements of standardized civilized construction sites. In addition, the traditional process is rough and has poor stability, making it difficult to meet the increasingly enhanced protection requirements; in particular, the steel bar welded guardrails are not rotatable and have high costs; the guardrails constructed with steel pipes and steering fasteners cannot meet the requirements of the gap width between the two staircases in the stairwell due to the influence of the steering fastener size, so that the guardrails are on the outside of the staircase, which cannot meet the requirements of installing footboards and guardrails. Summary of the invention

[0003] This solution provides a standardized temporary steel staircase that saves labor and effort to build.

[0004] In order to achieve the above-mentioned purpose, the present invention provides a standardized temporary steel staircase, including stair steps and railings; and also includes: a first magnet, a second magnet, a third magnet, a cavity, a hydraulic cylinder and a valve; a card slot is provided at both ends of the stair steps, and the stair steps are connected to the outer frame by snapping; the railing is assembled by a steel pipe and a connecting piece, and the railing and the stair steps cooperate with each other; one end of the valve is connected to the cavity, and the other end is connected to the outside; a railing slot is provided on the stair steps; the cavity is located at the bottom of the railing slot, and a movable plate is slidably provided on the cavity; the hydraulic cylinder is located in the side wall of the railing slot, and the hydraulic cylinder is connected to the cavity; the second magnet and the third magnet are both vertically slidably connected to the side wall of the railing slot, and a partition is provided between the second magnet and the third magnet; the third magnet is fixedly connected to the piston rod of the hydraulic cylinder; the third magnet is horizontally slidably connected to the side wall of the railing slot; the second magnet attracts the first magnet; and the third magnet repels the first magnet.

[0005] Principle of this scheme: The staircase steps are connected to the outer frame buckle through the card slot, and the railings are assembled with the connecting parts and the steel pipes on the construction site. The second magnet in the railing slot attracts the first magnet. The cavity is filled with liquid and the valve is in a closed state. Insert the railing into the railing slot on the staircase step, and the railing squeezes the movable plate to allow the liquid in the cavity to enter the hydraulic cylinder. The piston rod of the hydraulic cylinder moves upward, and the third magnet and the second magnet slide upward. The third magnet slides to a position relative to the first magnet, and the third magnet repels the first magnet to lock the railing. When the railing needs to be removed, open the valve to allow the liquid in the cavity to flow out, and the second magnet and the third magnet slide downward under the action of gravity. The two magnets slide to a position relative to the first magnet, and the second magnet attracts the first magnet to loosen the railing.

[0006] The beneficial effects of this solution are as follows: the staircase steps are directly connected to the external frame through buckles, which is convenient to assemble and disassemble and can be recycled; the railings are assembled according to different needs using materials on the construction site, which is low-cost and simple; the railing slots are set on the staircase steps, and there is no gap between the railings and the staircase steps, which plays a better protective role and is convenient to build stairs. The self-locking railings use the attraction and repulsion of magnets, which are simple and convenient to operate.

[0007] Furthermore, a transparent cavity is provided on the railing; a partition is provided in the transparent cavity, the partition is made of a memory alloy, and the partition divides the transparent cavity into a natural light-emitting section and an emergency light-emitting section; the natural light-emitting section is located above the emergency light-emitting section, and fluorescent powder is provided in the natural light-emitting section; the emergency light-emitting section is located at the bottom of the railing. Since the railing is relatively long, the bottom of the railing is not exposed to light when the light is irradiated. The emergency light-emitting section is not exposed to light and is in a darker state. The fluorescent powder in the natural light-emitting section absorbs light during the day, and the light emitted by the fluorescent powder can be seen at night or in the dark; in the event of a fire, the partition is deformed by high temperature, and the fluorescent powder falls into the emergency light-emitting section, and the emergency light-emitting section emits light to indicate a safe passage.

[0008] Furthermore, the contact end between the first magnet and the railing is provided with wear-resistant rubber. The first magnet and the railing are prone to friction, and the rubber can reduce the friction damage between the two; some railings contain iron, and the rubber makes it easy for the first magnet and the railing to separate.

[0009] Furthermore, a first limit block is provided on the first magnet, and a second limit block is provided on the railing slot; the first limit block cooperates with the second limit block to prevent the first magnet from escaping from the railing slot when sliding.

[0010] Furthermore, a stair transfer platform is provided at one end of the staircase flight to facilitate people to walk up and down.

[0011] Furthermore, the stair steps are provided with a sound-absorbing material layer, which can absorb noise and create a comfortable environment.

[0012] Furthermore, the handrail is overlapped with the outer frame hook ring in a simple and firm manner, thereby increasing the load-bearing capacity of the stairs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is a further detailed description through specific implementation methods:

[0018] The figure marks in the drawings of the specification include: stair step 1, slot 2, railing 3, natural light section 301, emergency light section 302, partition 303, connecting part 4, stair transfer plane 5, railing slot 6, hydraulic cylinder 7, magnet partition 8, movable plate 9, cavity 10, first magnet 11, second magnet 12 and third magnet 13.

[0019] The embodiment is basically as shown in the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 With attached Figure 4 As shown:

[0020] The main frame of the staircase 1 is a rectangular tube with a small deadweight. The staircase 1 is provided with a clamping groove 2 at both ends, and the staircase 1 is fixed to the outer frame through the clamping groove 2. This buckle connection method is easy to install and disassemble, and the staircase 1 can be recycled.

[0021] The bottom surface of the stair step 1 is provided with a sound-absorbing material layer, which can absorb sound, reduce the impact of noise, and create a comfortable environment.

[0022] A stair turntable surface 5 is provided at one end of the stair flight 1 to facilitate walking.

[0023] A railing slot 6 is provided on the staircase 1 for connecting the railing 3 so that there is no gap between the railing 3 and the staircase 1, which plays a better protective role. A cavity 10 is provided at the bottom of the railing slot 6, and the cavity 10 is filled with hydraulic oil. A movable plate 9 is provided at the top of the cavity 10, and the movable plate 9 slides up and down along the side wall of the cavity 10. The movable plate 9 has strict sealing properties, and the specific reference is to the piston. Hydraulic cylinders 7 are provided on the side walls at both ends of the railing slot 6, and the hydraulic cylinders 7 are connected to the cavity 10. A first magnet 11, a second magnet 12 and a third magnet 13 are provided in the side walls at both ends of the railing slot 6. The first magnet 11 is horizontally slidably connected to the side wall of the railing slot 6. The end of the first magnet 11 that contacts the railing 3 is provided with wear-resistant rubber, which can reduce the friction damage between the railing 3 and the first magnet 11. Some railings 3 contain iron, and the rubber can make the two easily separated and not affected by magnetism. A first limit block is provided on the first magnet 11, and a second limit block is provided on the railing slot 6 to match the first limit block on the first magnet 11, so as to prevent the first magnet 11 from escaping from the railing slot 6 when sliding. The second magnet 12 is vertically slidably connected with the third magnet 13 and the side wall of the railing slot 6. The first magnet 11 and the second magnet 12 have opposite magnetic poles and attract each other. The first magnet 11 and the third magnet 13 have the same magnetic poles and repel each other. The third magnet 13 is fixedly connected to the piston rod of the hydraulic cylinder 7, the second magnet 12 is located above the third magnet 13, and a magnet partition 8 is provided between the third magnet 13 and the second magnet 12, so that the third magnet 13 and the second magnet 12 do not affect each other. A valve is also provided on the railing slot 6, one end of the valve is connected to the cavity 10, and the other end is connected to the outside world.

[0024] The second magnet 12 attracts the first magnet 11. After the railing 3 is inserted into the railing slot 6, the railing 3 makes the movable plate 9 slide downward to squeeze the liquid in the cavity 10 into the hydraulic cylinder 7. The piston in the hydraulic cylinder 7 moves upward, and the third magnet 13 and the second magnet 12 slide upward with the piston rod. The third magnet 13 slides to a position relative to the first magnet 11. The third magnet 13 repels the first magnet 11 and locks the railing 3. When the railing 3 needs to be taken out, the valve is opened to allow the liquid in the cavity 10 to flow out. The second magnet 12 and the third magnet 13 return to their original positions under the action of gravity. The second magnet 12 attracts the first magnet 11, and the railing 3 is released. At this time, the railing 3 can be taken out.

[0025] The handrail 3 is temporarily assembled with the steel pipe on the construction site using the connector 4. The handrail 3 is assembled with the connector 4 using existing materials. The handrail 3 can be assembled according to specific needs, and the installation and disassembly are convenient. The handrail 3 is overlapped with the hook ring of the outer frame to fix the handrail 3, increase the load-bearing capacity of the ladder section, and make it more stable.

[0026] A transparent cavity is provided on the railing 3, and a partition 303 is provided in the transparent cavity. The partition 303 is made of a memory alloy and deforms when subjected to high temperature. The partition 303 divides the transparent cavity into a natural light-emitting section 301 and an emergency light-emitting section 302. The natural light-emitting section 301 is filled with fluorescent powder, which is a photo-energy storage luminous powder. This fluorescent powder stores light energy after being irradiated by natural light, fluorescent light, ultraviolet light, etc., and the light emitted by the fluorescent powder can be seen at night and in dark environments. The natural light-emitting section 301 is located above the emergency light-emitting section 302. Since the railing 3 is relatively long, the bottom of the railing is not irradiated by light when light is irradiated, and the emergency light-emitting section 302 is at the bottom of the railing 3. The natural light-emitting section 301 absorbs light during the day and illuminates at night. When a fire occurs, the temperature will rise. The partition 303 is made of a memory alloy. When the partition 303 is subjected to high temperature, it will deform, causing the fluorescent powder to fall into the emergency light-emitting segment 302. When the emergency light-emitting segment 302 emits light, the display pattern is an arrow, indicating the direction of the safe passage.

[0027] The operation method of this scheme is as follows: the staircase 1 is connected to the outer frame by the card slot 2, the handrail 3 is assembled using the construction site steel pipe and the connector 4, and then the handrail 3 is inserted into the handrail slot 6, and the handrail 3 is overlapped with the outer frame hook. The cavity 10 is filled with liquid and the valve is in a closed state. When the handrail 3 is not inserted into the handrail slot 6, the second magnet 12 is opposite to the first magnet 11, and the second magnet 12 attracts the first magnet 11. After the handrail 3 is inserted into the handrail slot 6, the movable plate 9 is squeezed to make the liquid in the cavity 10 enter the hydraulic cylinder 7, and the piston in the hydraulic cylinder 7 moves upward, driving the second magnet 12 and the third magnet 13 to slide upward, so that the third magnet 13 is opposite to the first magnet 11, and the third magnet 13 repels the first magnet 11, locking the handrail 3. When the handrail 3 needs to be taken out, the valve is opened to allow the liquid in the cavity 10 to flow out, the second magnet 12 and the third magnet 13 return to their original positions under the action of gravity, the second magnet 12 is opposite to the first magnet 11, the second magnet 12 attracts the first magnet 11, and the handrail 3 is released. The natural light-emitting section 301 absorbs light during the day, and the light emitted by the fluorescent powder can be seen at night or in the dark. In the event of a fire, the partition is deformed, and the fluorescent powder falls into the emergency light-emitting section 302, which emits light to indicate a safe passage. This type of staircase is easy to build, easy to disassemble, beautiful, low-cost, recyclable, and can also be used for lighting at night.
