Description

Technical Field

[0001] The present invention relates to the technical field of buildings, and particularly relates to a building with a protective wall. Background Art

[0002] With the acceleration of the urbanization process, various buildings have sprung up like mushrooms after rain, and the scale and complexity of buildings have also increased day by day. High-rise buildings, large commercial complexes, underground buildings, etc. have emerged continuously. While these buildings provide convenient places for people's living, working, entertainment, etc., they also bring potential safety hazards. During the daily use of buildings, the flow of people is frequent and intensive. Especially in some emergency situations, people will gather and quickly evacuate through the evacuation channels in the building.

[0003] However, in the event of an emergency, people are often in a state of extreme panic. Under the stress response, the ability of the brain to think rationally decreases. At this time, due to the large population density and hasty actions, people may run around in a hurry, making it difficult to accurately control their own movements and directions. They may hit the building wall panels or push the people around them onto the building wall panels, resulting in injuries to people. Summary of the Invention

[0004] Based on this, in order to solve the problem that people may hit the wall panels or push the people around them onto the wall panels when running around in a hurry in the evacuation channels of buildings in case of an emergency, resulting in injuries to people, the purpose of the present invention is to provide a building with a protective wall, and its specific technical solution is as follows: A building with a protective wall includes an activity area, an equipment area, and a protection area. The activity area is used for people to carry out activities; the equipment area is used to place various equipment and facilities; the protection area is used for evacuation protection in case of an emergency.

One end of the fixing structure passes through the connecting bottom plate and is fixedly connected to the second buffer member.

[0009] Further, the first buffer member includes a first buffer plate, a telescopic rod, a first elastic member and a second buffer plate. The first buffer plate is fixedly connected to the connecting block. One end of the first elastic member and the telescopic rod are respectively fixedly connected to the first buffer plate.

The protection wall includes an outer wall structure and several identical inner wall structures. When people run around in a hurry in the protection area and bump into the wall panels by themselves or push the people around them onto the wall panels, the load-bearing components can first bear the impact force during the collision, and then transfer these impact forces to the buffer structure. The buffer structure can absorb and disperse the energy generated by the collision, convert the impact force during the collision into the deformation energy of the buffer structure, thereby reducing the impact force received by the human body and reducing the risk of people being injured, providing physical protection for personnel. The movable structure further consumes the collision energy and acts together with the buffer structure to enhance the overall buffering effect and more effectively prevent personnel from being injured due to collision. The adjacent inner wall structures are mutually clamped, and each inner wall structure is fixedly connected to the outer wall structure, ensuring that the protection wall panels will not shake or collapse easily when subjected to external forces such as personnel collision, providing a stable and reliable evacuation environment for personnel, enabling people to evacuate under relatively safe conditions.

[0021] In the present invention, the "first" and "second" do not represent specific quantities and orders, but are only used for name distinction.

[0022] As Figures 1 - 10 As shown, a building with a protective wall in an embodiment of the present invention includes an activity area 1, an equipment area 2, and a protection area 3. The activity area 1 is used for people to carry out activities; the equipment area 2 is used to place various equipment and facilities; the protection area 3 is used for evacuation protection in case of emergency. A protective wall 4 and a staircase 5 are provided in the protection area 3. The protective wall 4 includes an outer wall structure 41 and a number of identical inner wall structures 42. Each inner wall structure 42 is fixedly connected to the outer wall structure 41, and each inner wall structure 42 surrounds the staircase 5. Adjacent inner wall structures 42 are snap-connected to each other; wherein, the inner wall structure 42 includes a load-bearing member 421, a buffer structure 422, a movable structure 423, and a fixing structure 424. The movable structure 423 is fixedly connected to both ends of the load-bearing member 421 respectively. The buffer structure 422 is arranged between the movable structures 423 and is fixedly connected to the load-bearing member 421. The fixing structure 424 is fixedly connected to the end of the buffer structure 422 away from the load-bearing member 421, and the fixing structure 424 is fixedly connected to the outer wall structure 41. By providing the protection area 3, a protective wall 4 is provided in the protection area 3. The protective wall 4 includes an outer wall structure 41 and a number of identical inner wall structures 42. When people run around in a hurry in the protection area 3 and bump into the wall panel by themselves or push the people around them onto the wall panel, the load-bearing member 421 can first bear the impact force during the collision, and then transfer these impact forces to the buffer structure 422. The buffer structure 422 can absorb and disperse the energy generated by the collision, convert the impact force during the collision into the deformation energy of the buffer structure 422, thereby reducing the impact force on the human body and reducing the risk of people being injured, providing physical protection for personnel. The movable structure 423 further consumes the collision energy, and together with the buffer structure 422, enhances the overall buffer effect and more effectively avoids personnel being injured due to collision. Adjacent inner wall structures 42 are snap-connected to each other, and each inner wall structure 42 is fixedly connected to the outer wall structure 41, ensuring that the protective wall 4 will not shake or collapse easily when subjected to external forces such as personnel collision, providing a stable and reliable evacuation environment for personnel, enabling people to evacuate under relatively safe conditions.

[0023] Specifically, in this embodiment, there are two movable structures 423, which are respectively fixedly connected to both ends of the load-bearing member 421. The movable structure 423 includes a telescopic plate 4231 and a sleeve plate 4232. The telescopic plate 4231 is arranged inside the sleeve plate 4232, and one end of the telescopic plate 4231 is fixedly connected to the load-bearing member 421. The movable structure 423 is used for auxiliary buffering. During the buffering process, the movable structure 423 can work together with the first buffer member 4222 and the second buffer member 4223. When the first buffer member 4222 and the second buffer member 4223 start to absorb and disperse the collision energy, the movable structure 423 further consumes the collision energy through the sliding of the telescopic plate 4231 inside the sleeve plate 4232. A convex block is arranged on the sleeve plate 4232 of one of the movable structures 423, and a groove is arranged on the sleeve plate 4232 of the other movable structure 423. The convex block on one of the inner wall structures 42 is adaptively clamped with the groove on the adjacent other inner wall structure 42.

[0024] As a preferred embodiment of the present invention, it may further have the following additional technical features: The load-bearing member 421 includes an outer layer structure 4211, an inner layer structure 4212, and a buffer soft pad 4213. The inner layer structure 4212 is arranged inside the outer layer structure 4211 and fixedly connected to the outer layer structure 4211. The outer layer structure 4211 is respectively fixedly connected to the buffer structure 422 and the movable structure 423. The buffer soft pad 4213 is fixedly connected to one end of the outer layer structure 4211 away from the buffer structure 422. The outer layer structure 4211, as the outermost layer of the load-bearing member 421, not only provides basic support for the entire load-bearing member 421, but also plays a role in protecting the internal structure. It can withstand a certain amount of external force impact and prevent the internal structure from being directly damaged. The inner layer structure 4212 is arranged inside the outer layer structure 4211 and fixedly connected to the outer layer structure 4211, enhancing the overall load-bearing capacity of the load-bearing member 421. When subjected to external force, it can share the pressure with the outer layer structure 4211 to ensure the safety of the protective wall 4. When a person collides with the wall panel, the buffer soft pad 4213 can absorb and disperse part of the impact force, reducing the risk of personal injury. In this embodiment, the surface of the buffer soft pad 4213 adopts an anti-slip texture design, providing lateral friction while absorbing the impact and guiding the person to maintain a stable posture.

[0025] As a preferred embodiment of the present invention, it may also have the following additional technical features: the outer layer structure 4211 includes a first connecting plate 42111, a second connecting plate 42112 and a reinforcement plate 42113, two first connecting plates 42111 and two second connecting plates 42112 are respectively provided, and the two ends of the two first connecting plates 42111 are respectively clamped with the two second connecting plates 42112, and a plurality of reinforcement plates 42113 are provided and arranged between the two first connecting plates 42111, the first connecting plates 42111 and the second connecting plates 42112 are set as flame-retardant gypsum boards, and each reinforcement plate 42113 is set as a fiber cement board, and each reinforcement plate 42113 is triangular, and adjacent reinforcement plates 42113 are arranged alternately in positive and inverted triangles, and the quadrilateral frame cooperates with the triangular reinforcement plates 42113 to form a truss system. When subjected to lateral impact, the clamping nodes absorb energy through friction and deformation, and the impact resistance is improved by 60% compared with the single-plate structure, effectively preventing the partial collapse of the protective wall 4. The cushion pad 4213 is fixedly connected to one of the first connecting plates 42111. A quadrilateral frame is formed by two first connecting plates 42111 and two second connecting plates 42112, and a clamping design is used to replace traditional welding or bolting, which improves the on-site installation efficiency by more than 40%. This modular structure can replace damaged plates individually during post-disaster repair, shortening the maintenance cycle.

[0026] As a preferred embodiment of the present invention, it may also have the following additional technical features: the inner layer structure 4212 includes a first cloth layer 42121, a polyurethane sandwich panel 42122, a second cloth layer 42123, a rock wool insulation layer 42124 and a third cloth layer 42125, the first cloth layer 42121, the polyurethane sandwich panel 42122, the second cloth layer 42123, the rock wool insulation layer 42124 and the third cloth layer 42125 are connected in sequence, a plurality of grids are arranged on the first cloth layer 42121, the second cloth layer 42123 and the third cloth layer 42125 are both arranged as glass fiber cloth, and the first cloth layer 42121 is arranged on the side close to the buffer pad 4213. In this embodiment, the impact force transmission path of the load-bearing component 421 is as follows: buffer cushion 4213 (level 1) → outer layer structure 4211 (level 2) → first cloth layer 42121 (level 3) → polyurethane sandwich panel 42122 (level 4) → second cloth layer 42123 (level 5) → rock wool layer compression (level 6) → third cloth layer 42125 (level 7) → outer layer structure 4211 (level 8), and a gradient fire barrier can be formed at the same time.

[0027] As a preferred embodiment of the present invention, it may also have the following additional technical features: the buffer structure 422 includes a connecting block 4221, a first buffer 4222, a second buffer 4223 and a connecting bottom plate 4224, the connecting block 4221 is fixedly connected to the load-bearing component 421, the end of the connecting block 4221 away from the load-bearing component 421 is fixedly connected to the first buffer 4222, the second buffer 4223 is fixedly connected to the end of the first buffer 4222 away from the connecting block 4221, the connecting bottom plate 4224 is fixedly connected to the end of the second buffer 4223 away from the first buffer 4222, and the fixed structure 424 is fixedly connected to the second buffer 4223 through one end of the connecting bottom plate 4224. The connecting block 4221 is directly fixed to the load-bearing component 421, and when a person collides, the first buffer 4222 immediately intervenes to reduce the initial impact peak through elastic deformation. After the first buffer component 4222 reduces the initial impact peak, the second buffer component 4223 can further play a role in effectively buffering the remaining collision force, so that the collision force is gradually attenuated during the transmission process, avoiding the problem of insufficient buffering capacity or excessive buffering that may occur in a single buffer component, and can more accurately control the buffering effect, thereby better protecting people from collision injuries.

[0028] As a preferred embodiment of the present invention, it may also have the following additional technical features: the first buffer member 4222 includes a first buffer plate 42221, a telescopic rod 42222, a first elastic member 42223 and a second buffer plate 42224, the first buffer plate 42221 is fixedly connected to the connecting block 4221, the first elastic member 42223 and one end of the telescopic rod 42222 are respectively fixedly connected to the first buffer plate 42221, and the first elastic member 42223 is arranged around the telescopic rod 42222, so that the elastic member can evenly distribute stress when subjected to force, giving full play to its elastic buffering characteristics. The first elastic member 42223 and one end of the telescopic rod 42222 away from the first buffer plate 42221 are respectively fixedly connected to the second buffer plate 42224. The telescopic rod 42222 plays a supporting and guiding role in the buffering process, which limits the deformation direction of the first elastic member 42223, so that it can only be elastically deformed along the preset axial direction, avoiding the problem of reduced buffering efficiency and structural instability caused by the arbitrary deformation of the elastic member. When the collision force acts, the first elastic member 42223 rapidly undergoes elastic deformation, absorbs and stores the collision energy, thereby effectively reducing the initial impact peak. At the same time, the telescopic rod 42222 expands and contracts as the first elastic member 42223 deforms, further enhancing the controllability and stability of the buffering process. The second buffer plate 42224, as the fixed end of the first elastic member 42223 and the telescopic rod 42222, evenly transfers the absorbed collision force to the subsequent second buffer member 4223, thereby achieving a smooth transition of the buffering energy.

[0029] As a preferred embodiment of the present invention, it may further have the following additional technical features: The second buffer member 4223 includes a buffer pressing block 42231, a support plate 42232, a buffer pressing plate 42233, a telescopic sleeve 42234, a second elastic member 42235, a transition structure 42236, a limiting plate 42237, and a third elastic member 42238. The buffer pressing plate 42233 is fixedly connected to the first buffer member 4222. The limiting plate 42237 passes through the transition structure 42236 and is fixedly connected to the buffer pressing block 42231. The support plate 42232 is fixedly connected to the top end of the buffer pressing block 42231. Telescopic sleeves 42234 are fixedly connected to the four sides of the top end of the support plate 42232. The end of the telescopic sleeve 42234 away from the support plate 42232 is fixedly connected to the first buffer member 4222. The transition structure 42236 is inserted on the support plate 42232 and is movably connected to the buffer pressing block 42231. One end of the second elastic member 42235 is fixedly connected to the transition structure 42236, and the buffer pressing plate 42233 is fixedly connected to the end of the second elastic member 42235 away from the transition structure 42236. One end of the third elastic member 42238 is fixedly connected to the bottom of the inner surface of the buffer pressing block 42231, and the end of the third elastic member 42238 away from the buffer pressing block 42231 is fixedly connected to the transition structure 42236. The buffer pressing block 42231 is fixedly connected to the connecting bottom plate 4224. The limiting plate 42237 restricts the movement trajectory of the transition structure 42236, preventing it from shifting or shaking, ensuring that the buffering action proceeds along the preset direction, and improving the accuracy and stability of buffering. The support plate 42232 is fixedly connected to the top end of the buffer pressing block 42231, and at the same time, the telescopic sleeves 42234 around its top end are also connected to the first buffer member 4222, which not only enhances the stability of the buffer pressing block 42231 but also further optimizes the displacement adjustment during buffering through the telescopic characteristics of the telescopic sleeves 42234. When a collision force acts, the telescopic sleeve 42234 can expand and contract according to the buffering requirements to assist the buffering action, making the buffering process smoother and more stable. The transition structure 42236 is inserted on the support plate 42232 and is movably connected to the buffer pressing block 42231, and can move relatively within the buffer pressing block 42231, cooperating with the second elastic member 42235 and the third elastic member 42238 to achieve multi-stage buffering. One end of the second elastic member 42235 is fixed to the transition structure 42236, and the other end is connected to the buffer pressing plate 42233. During buffering, it can respond quickly and absorb part of the collision energy through elastic deformation to reduce the impact peak value. One end of the third elastic member 42238 is fixed to the bottom of the inner surface of the buffer pressing block 42231, and the other end is connected to the transition structure 42236. On the basis of the buffering of the second elastic member 42235, it further buffers the remaining collision force to form a multi-level buffering effect, effectively improving the buffering efficiency.The buffer pressing block 42231 is fixedly connected to the connecting bottom plate 4224, and the remaining impact force after multi-stage buffering by the first buffer member 4222 and the second buffer member 4223 is smoothly transmitted to the connecting bottom plate 4224, and then the connecting bottom plate 4224 performs subsequent force transmission or dispersion processing to ensure that the entire buffer structure 422 can effectively protect the safety of personnel.

[0030] As a preferred embodiment of the present invention, it may further have the following additional technical features: The transition structure 42236 includes a supporting member 42239 and a force-receiving member 42230. The supporting member 42239 is fixedly connected to the force-receiving member 42230 to form a stable overall structure, ensuring that the two can work together during the buffering process to jointly cope with the impact force. An activity groove is provided on the supporting member 42239, and the limiting plate 42237 is arranged through the activity groove, realizing the limitation and guidance of the movement track of the transition structure 42236. During buffering, the limiting plate 42237 slides in the activity groove, which not only ensures that the transition structure 42236 can be displaced in a preset direction, but also prevents it from shifting or shaking, improving the accuracy and stability of buffering. The force-receiving members 42230 are symmetrically distributed at the bottom end of the supporting member 42239, avoiding structural deformation or damage caused by uneven force.

[0032] As a preferred embodiment of the present invention, it may further have the following additional technical features: A monitoring device 44 and an escape sign are provided in the protection area 3. The monitoring device 44 includes a pedestrian recognition device 441, a weight sensor 442, a height ultrasonic monitor 443, and a central processing device. The pedestrian recognition device 441, the weight sensor 442, and the height ultrasonic monitor 443 are all installed at the entrance of the protection area 3. The pedestrian recognition device 441, the weight sensor 442, and the height ultrasonic monitor 443 are respectively electrically connected to the central processing device. The pedestrian recognition device 441 is used to collect the external appearance characteristics of personnel. The weight sensor 442 is used to collect the weight information of personnel. The height ultrasonic monitor 443 is used to collect the height information of personnel. The central processing device collects the corresponding data for real-time analysis, and based on the linear model constructed by BMI and heart rate, predicts the fatigue trend of vulnerable groups and potential congestion areas during the evacuation process. Through network collaborative operation, real-time transmission of information and system response are achieved, thereby improving the evacuation efficiency and the safety guarantee ability of vulnerable groups during the evacuation process. Based on the prediction results of the central processing device, the system can identify children who may be fatigued or fatigued due to injury, and guide them to take other routes through the evacuation signs and alarm device 444. At the same time, the system will issue an emergency alarm, including two core messages: one is to prompt the on-site personnel to assist vulnerable groups such as children in a timely manner, and the other is to notify the security personnel to quickly go to the target area to implement rescue. In addition, in this embodiment, the data is input into the central processor device for centralized processing and temporary storage, and the information will be automatically deleted when the corresponding person leaves to avoid infringing on personal information. The pedestrian recognition device 441 adopts the existing camera technology.

[0033] As a preferred embodiment of the present invention, it may further have the following additional technical features: The monitoring device 44 includes an alarm device 444. The alarm device 444 is installed above each platform of the staircase 5. The alarm device 444 is electrically connected to the central processing device. When the central processing device detects and analyzes a high fatigue risk or too high a crowd density, it will automatically trigger an alarm to prompt the on-site evacuees to assist vulnerable groups, and the security personnel will immediately intervene and guide the personnel who have not entered the protection area 3 to choose other protection areas 3 through the escape signs. Research shows that the BMI and heart rate values of children in the evacuation staircase 5 can be represented by a linear mathematical equation. In this embodiment, an experimental analysis of children is carried out based on the situation of evacuating upward in the underground space, as Figure 9 shown, which is a prediction model diagram of the upward evacuation heart rate of children based on BMI. Among them, the X-axis represents the upward height, the Y-axis represents the average heart rate, and the children are divided into a thin group, a normal group, an overweight group, and an obese group for analysis. The structural design of the building with a protective wall in this embodiment is reasonable and convenient to use. For other devices with similar usage requirements, this structure can also be adopted. In this embodiment, when people run in a hurry and hit the wall panel or push each other against the wall panel, the building with a protective wall can absorb the impact energy, reduce the injury to people, lower the risk of injury, avoid delaying the evacuation time due to injury, and help people escape from the scene more smoothly and timely through the protection area 3 in case of emergency.
