Description

Technical Field

[0001] This application relates to the field of underground space ventilation technology, and in particular to an energy-saving basement staircase structure. Background Technology

[0002] The area below the outdoor ground level in a large building is usually called a basement. Building a basement below the ground floor can improve the efficiency of building land use. Most high-rise buildings have a deep foundation. Making full use of this depth to build a basement has excellent economic and practical effects. A basement generally consists of a roof slab, a floor slab, side walls, stairs, doors and windows, and light wells. The roof slab of the basement is made of cast-in-place or precast concrete.

[0003] However, it has significant deficiencies in ventilation. Its ventilation needs mostly rely on mechanical ventilation systems, such as exhaust fans and fresh air systems, which operate continuously to maintain air circulation and quality. However, this inevitably leads to a large amount of electricity consumption, which is contrary to the current green and energy-saving building concept. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide an energy-saving basement staircase structure.

[0005] The technical solution of this application is as follows: an energy-saving basement staircase structure includes a basement body, inside which a staircase structure body is installed. The staircase structure body includes side supports, guardrails, stair slab boxes, and air inlet pipes. Multiple stair slab boxes are provided. A sliding plate is slidably connected inside each stair slab box. A tread is fixedly connected to the top of the sliding plate. An air inlet pipe is fixedly connected to one side of each stair slab box. An exhaust pipe is fixedly connected to the bottom of each stair slab box. Two limiting grooves are opened on both sides of the inner wall of each stair slab box. A reset component is installed inside each limiting groove. A one-way component is installed inside each exhaust pipe and air inlet pipe.

[0006] By adopting the above technical solutions, this design can achieve ventilation through daily human activities, greatly reducing the energy consumption of basement ventilation, which is in line with the concept of green and energy-saving buildings and effectively reduces building operating costs.

[0007] In a preferred embodiment, the reset assembly includes a limiting rod fixedly connected inside the limiting groove. A limiting block is slidably connected to the outer side of each limiting rod. A reset spring is sleeved on the outer side of each limiting rod and below the limiting block. The two limiting blocks are fixedly connected to the two sides of the slide plate, respectively.

[0008] By adopting the above technical solution, through the coordinated operation of the limiting groove, limiting rod, limiting block and return spring, not only can the pedal be stably reset, but the sliding range of the slide can also be limited.

[0009] In a preferred embodiment, the one-way component includes a one-way valve b fixedly installed inside the air intake pipe, the one-way valve b being used to unidirectionally introduce air from the air intake pipe into the stair slab box, and a one-way valve a fixedly installed inside the exhaust pipe, the one-way valve a being used to unidirectionally introduce air from the stair slab box into the basement body.

[0010] By adopting the above technical solution, and through the combined use of one-way valve a and one-way valve b, the phenomenon of air backflow can be prevented.

[0011] In a preferred embodiment, two side supports are provided, and multiple stair tread boxes are fixedly installed between the two side supports. The air inlet pipe is fixedly installed inside one of the side supports. Two guardrails are provided, and the guardrails are fixedly connected to the top of the corresponding guardrails.

[0012] By adopting the above technical solutions, the stability and safety of the staircase structure are ensured.

[0013] In a preferred embodiment, the end of the air inlet duct away from the basement body extends to the outside of the basement body, and a filter frame is provided at the extension of the air inlet duct.

[0014] By adopting the above technical solution and setting the filter frame, dust, debris and other pollutants in the outside air can be effectively filtered to ensure that the air entering the basement is clean.

[0015] In a preferred embodiment, the filter frame is internally threaded with multiple locking bolts, and the filter frame is connected to the air inlet pipe via locking bolts.

[0016] By adopting the above technical solutions, disassembly and cleaning are facilitated, and maintenance difficulty is reduced.

[0017] In a preferred embodiment, a fixing opening is provided at the top of the basement body, and a non-powered wind cap is installed at the top of the basement body and above the fixing opening.

[0018] By adopting the above technical solution and setting up a non-powered wind cap, wind pressure can be used to further promote air circulation and assist in the discharge of polluted air.

[0019] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0020] 1. In this application, when the step is pressed down by a person, the sliding plate will squeeze the air in the stair slab box and discharge the air into the basement body through the one-way component. When the step is lifted, the reset component will drive the sliding plate and step back to their original positions, creating a negative pressure in the stair slab box. At this time, outside air can be introduced into the stair slab box through the air inlet pipe and the air intake pipe. This process is repeated, thus enabling fresh outside air to be introduced into the basement body without the need for electricity. This effectively improves the hot and humid environment of the basement body. This design can achieve the purpose of ventilation by relying on daily human activities, which greatly reduces the energy consumption of basement body ventilation, conforms to the green and energy-saving building concept, and effectively reduces building operating costs.

[0021] 2. In this application, by setting up a non-powered wind cap, wind pressure can be used to further promote air circulation, assist in the discharge of polluted air, and cooperate with the ventilation structure of the staircase structure to improve the overall air quality and achieve the purpose of air circulation.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-5 An energy-saving basement staircase structure includes a basement body 1, inside which a staircase structure body 2 is installed. The staircase structure body 2 includes side supports 201, guardrails 202, stair slab boxes 203, and air inlet pipes 204. Multiple stair slab boxes 203 are provided. A sliding plate 9 is slidably connected inside the stair slab box 203. A step 8 is fixedly connected to the top of the sliding plate 9. An air inlet pipe 6 is fixedly connected to one side of the stair slab box 203. An exhaust pipe 4 is fixedly connected to the bottom of the stair slab box 203. Two limiting grooves 10 are opened on both sides of the inner wall of the stair slab box 203. A reset component is installed inside the limiting groove 10. A one-way component is installed inside the exhaust pipe 4 and the air inlet pipe 6. When the step 8 is turned off... When step 8 is pressed down by personnel, the sliding plate 9 will squeeze the air in the stair plate box 203 and discharge the air into the basement body 1 through the one-way component. When step 8 is lifted, the reset component will drive the sliding plate 9 and step 8 to reset, creating a negative pressure in the stair plate box 203. At this time, outside air can be introduced into the stair plate box 203 through the air inlet pipe 204 and the air inlet pipe 6. This process is repeated, thus enabling fresh outside air to be introduced into the basement body 1 without power, effectively improving the hot and humid environment of the basement body 1. This design can achieve the purpose of ventilation by relying on daily personnel activities, which greatly reduces the energy consumption of ventilation in the basement body 1, conforms to the green and energy-saving building concept, and effectively reduces the building operating cost.

[0030] Specifically, the reset assembly includes a limiting rod 12 fixedly connected inside the limiting groove 10. Limiting blocks 13 are slidably connected to the outer sides of the limiting rod 12. Through the coordinated operation of the limiting groove 10, the limiting rod 12, and the limiting blocks 13, not only is the stable reset of the pedal 8 ensured, but the sliding range of the slide plate 9 is also limited to prevent structural damage. Reset springs 11 are sleeved on the outer sides of the limiting rod 12 and below the limiting blocks 13. The two limiting blocks 13 are fixedly connected to both sides of the slide plate 9. The reset springs 11 enable rapid reset even when the pedal 8 is not pressed. The one-way assembly includes a one-way valve b7 fixedly installed inside the intake pipe 6. 7 is used to guide the air in the air inlet pipe 204 into the stair slab box 203 in one direction. The exhaust pipe 4 is fixedly installed with a one-way valve a5. By using the one-way valve a5 and the one-way valve b7 together, the backflow of air can be prevented. The one-way valve a5 is used to guide the air in the stair slab box 203 into the basement body 1 in one direction. There are two side supports 201. Multiple stair slab boxes 203 are fixedly installed between two side supports 201. The air inlet pipe 204 is fixedly installed inside one of the side supports 201 to ensure the stability and safety of the stair structure body 2. There are two guardrails 202. The guardrails 202 are fixedly connected to the top of the corresponding guardrails 202.

[0031] Specifically, the end of the air inlet duct 204 furthest from the basement body 1 extends to the outside of the basement body 1. A filter frame 14 is installed at the extension of the air inlet duct 204. The filter frame 14 can effectively filter dust, debris and other pollutants in the outside air, ensuring that the air entering the basement is clean. Multiple locking bolts 15 are connected to the internal threads of the filter frame 14. The filter frame 14 and the air inlet duct 204 are connected by the locking bolts 15, which facilitates disassembly and cleaning and reduces maintenance difficulty. A fixing opening is opened at the top of the basement body 1. A non-powered vent 3 is installed at the top of the basement body 1 and above the fixing opening. The non-powered vent 3 can use wind pressure to further promote air circulation and assist in the discharge of polluted air. It works in conjunction with the ventilation structure of the staircase body 2 to improve the overall air quality and achieve the purpose of air circulation.

[0032] Working principle: First, when a worker steps on the treadle 8, the sliding plate 9 compresses the air inside the stair slab box 203. Through the one-way valve a5, the air is discharged into the basement body 1 via the exhaust pipe 4. When the treadle 8 is lifted, the coordinated action of the limiting groove 10, limiting rod 12, limiting block 13, and return spring 11 ensures not only stable reset of the treadle 8 but also limits the sliding range of the sliding plate 9, preventing structural damage. When the treadle 8 and sliding plate 9 are reset and raised, a negative pressure is created inside the stair slab box 203. At this time, outside air can be released through the air inlet pipe 204. The air is introduced into the intake pipe 6 and then discharged into the stair slab box 203. This process is repeated to allow fresh outside air to be introduced into the basement body 1 without the need for electricity. This effectively improves the hot and humid environment of the basement body 1. This design can achieve the purpose of ventilation by relying on daily human activities, which greatly reduces the energy consumption of ventilation in the basement body 1. This is in line with the concept of green and energy-saving buildings. Furthermore, by setting up the non-powered wind cap 3, the wind pressure can be used to further promote air circulation and assist in the discharge of polluted air. This works in conjunction with the ventilation structure of the stair structure body 2 to improve the overall air quality and achieve the purpose of air circulation.
