Description

Technical Field

[0001] The present invention relates to the technical field of building construction safety protection, and in particular to a construction site safety protection system and a security control method. Background Art

[0002] Currently, many high-rise buildings require scaffolding for exterior wall construction. To prevent falling objects, flexible protective nets are required around the scaffolding. Existing solutions include installing steel mesh inside the protective net to enhance its protection and ensure construction safety.

[0003] However, neither steel mesh nor protective nets can prevent granular or sharp construction debris or tools from passing through and falling, posing a potential safety hazard. More importantly, existing protective facilities lack a safety education function. Since worker subjective factors play a significant role in safety accidents, if technical improvements could be made to ensure that the protective system not only provides a safety function but also provides regular safety education and control for workers in conjunction with on-site construction, this could significantly enhance workers' subjective safety awareness and address the issue of falling objects from heights at a deeper level. Summary of the Invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a construction site safety protection system and a security control method.

[0005] To achieve the above object, the technical solution of the present invention is:

[0006] A construction site safety protection system includes an anti-fall mechanism and a safety warning control mechanism. The anti-fall mechanism includes a plurality of anti-fall units, each of which includes a first steel plate, a second steel plate, a partition, a clamp, and a connecting plate. Through holes are evenly distributed on the first steel plate and the second steel plate, and the through holes of the first steel plate and the second steel plate are staggered.

[0007] The partitions are evenly distributed between the first steel plate and the second steel plate in the longitudinal direction, and the two ends of the partitions are fixedly connected to the first steel plate and the second steel plate respectively, forming a longitudinal channel between adjacent partitions; the outer surface of the first steel plate is provided with a plurality of clamps for connecting to the scaffolding, and the upper and lower ends of the first steel plate are provided with outwardly protruding connecting plates, and the connecting plates are provided with first bolt holes. The plurality of anti-fall units are fixedly connected by bolts and fixedly connected to the scaffolding by clamps, and the longitudinal channels of the upper and lower adjacent anti-fall units are aligned with each other;

[0008] The safety warning control mechanism includes a controller, an impact force sensor, a display, a camera, a fixed plate, and a support plate. A fixed plate is provided in the longitudinal channel as needed. The fixed plate is fixedly connected to the partitions on both sides of the longitudinal channel by bolts. An impact force sensor is provided on the upper surface of the fixed plate. The top of the impact force sensor is fixedly connected to the support plate. The side end face of the support plate is gap-matched with the inner surface of the partition. The camera is set at the construction site, and the display is set at a gathering place outside the construction site. The impact force sensor and the camera are respectively connected to the controller signal through wires, and the controller is electrically connected to the display through wires.

[0009] Preferably, the partition is provided with a plurality of threaded holes at one end facing the first steel plate, and the partition is fixedly connected to the first steel plate by bolts; the first steel plate and the second steel plate are both square structures, and the outermost partition is provided with a through hole, and adjacent anti-fall units are connected by high-strength bolts passing through the through holes and locked by nuts.

[0010] Preferably, the inner surface of the second steel plate is welded to the end of the partition, and connecting plates are also provided at the upper and lower ends of the second steel plate. A second bolt hole is provided on the connecting plate of the second steel plate, and the bottom of the anti-fall unit located at the lowest layer is also connected to the base plate by bolts.

[0011] Preferably, the controller is provided with a storage unit, a conversion unit and an output unit. The storage unit is used to store the impact force data and the video acquisition information. The conversion and analysis unit is used to convert the impact force data into the corresponding accident scene animation, and analyze which construction workers performed which construction operations that caused the falling objects based on the video acquisition information and the time information of the impact force sensor sending the signal; the output unit is used to transmit the simulated accident scene animation to the display.

[0012] Preferably, the diameter of the through hole on the first steel plate is larger than the diameter of the through hole on the second steel plate.

[0013] A security control method combined with a construction site includes the following steps:

[0014] (1) Build a scaffold outside the building and set up an anti-fall mechanism outside the scaffold. During the erection process, first fix the bottom plate to the bottom of the anti-fall unit on the bottom layer with bolts. After the connection, the bottom plate seals the bottom end of the anti-fall unit, and the anti-fall unit is fixed to the scaffold with a clamp; then build the anti-fall unit on the upper layer, and align the upper and lower adjacent anti-fall units with each other. In this way, build multiple layers of anti-fall units until the required height is reached;

[0015] (2) According to the construction situation, install fixed plates of different heights in different longitudinal channels by bolts, install the impact force sensor on the fixed plate, and fix the supporting plate on the top of the impact force sensor. When installing, first remove the first steel plate at the corresponding position, and fix the first steel plate back to its original position after installation;

[0016] (3) Deploy several cameras at the construction site to ensure that they can capture possible falling objects;

[0017] (4) Place the controller and display in a gathering place outside the construction site, connect the electrical components with wires, and connect them to the power supply;

[0018] (5) When an object passes through the through hole of the first steel plate and falls onto the supporting plate, the controller records the impact force data transmitted by the impact force sensor and the time when the object fell. Then, the controller converts the impact force data into a corresponding accident scene animation through the conversion and analysis unit, and analyzes which construction workers performed which construction operations that caused the object to fall based on the video acquisition information and the time information when the impact force sensor sent the signal.

[0019] (6) When workers gather in a gathering place, a safety education meeting is held. During the meeting: first, the specific circumstances of the falling object are reported, including the time of the falling object and the impact force data. The cause of the falling object is reported based on the video collection information, and the original video screen is played. Then, the converted accident scene animation is played through the display. Safety education is carried out in combination with the accident scene animation to promote workers to enhance their safety awareness.

[0020] Preferably, in the step (5), the method for converting the accident scene animation is as follows: assuming that the impact force data occurs on a person, and simulating the degree of injury that the person may suffer based on the data through a preset program, and then calling the accident scene animation preset in the storage unit based on the simulation results.

[0021] Preferably, in the step (5), it is assumed that the impact force data occurs on a person, and the person is a worker, a pedestrian, an elderly person, a child, a person wearing a helmet, a person not wearing a helmet, a pregnant woman or other injured person; and the falling object that causes the impact force is concrete particles, steel nails, tools or other possible falling objects at the construction site. Different accident scene animations are displayed according to the different injured objects and the different possible falling objects.

[0022] Preferably, when falling objects occur in multiple longitudinal channels, the accident scene animation is converted according to the impact force data at different heights, and in step (6), the accident scene animation is explained according to the impact force and injury degree at different heights.

[0023] Preferably, in the step (6), combined with the explanation of security knowledge, the person responsible for the falling object accident is criticized and educated, and the accident record is made. When the accident record of the same person reaches a preset number of times, the person responsible is upgraded.

[0024] The construction site safety protection system and security control method of the present invention have the following beneficial effects:

[0025] 1. The safety protection system of the present invention can fully meet the needs of preventing falling objects at the construction site, and has a good effect in preventing falling objects. The staggered through holes completely avoid the harm of falling objects, ensure ventilation, and falling objects can only fall through the longitudinal channel; at the same time, the present invention is also provided with a safety warning control mechanism, which can collect the impact force data of falling objects at the construction site and video information of the construction site in real time, and provide materials for safety education that are combined with the workers' personal experience and their own interests, so that the anti-falling mechanism and the safety warning control mechanism can be closely combined, and safety education can be received during the construction process, which in turn promotes construction safety.

[0026] 2. Conventional safety education is conducted in the classroom through paper or video information, and some are conducted through simulated on-site devices. However, these safety educations are separated from the actual construction site and have no direct relevance to the workers' personal feelings and interests. Therefore, it is difficult for workers to have a profound personal experience, so it is difficult to stimulate the workers' subjective initiative. The present invention overcomes this defect by combining a security control method with a construction site. During the education process, the impact force data collected comes from the construction site where the workers personally participate. After converting the impact force data into an accident scene animation, the workers can intuitively understand that even a tiny falling object can cause irreparable accident injuries. Therefore, the workers' sensory and emotional experiences can be fully mobilized, and by combining education with the workers' personal interests, the workers can be stimulated to have a significant safety awareness. Since this safety awareness is autonomous rather than passively accepted, it can have a positive impact on construction safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Example 2:

[0043] Based on Example 1, this example discloses:

[0044] A security control method combined with the construction site, reference Figure 1-5 As shown, the following steps are included:

[0045] (1) Build a scaffold outside the building and set up an anti-fall mechanism outside the scaffold. During the erection process, first fix the bottom plate to the bottom of the anti-fall unit on the bottom layer with bolts. After the connection, the bottom plate seals the bottom end of the anti-fall unit, and the anti-fall unit is fixed to the scaffold with a clamp; then build the anti-fall unit on the upper layer, and align the upper and lower adjacent anti-fall units with each other. In this way, build multiple layers of anti-fall units until the required height is reached;

[0046] (2) According to the construction situation, install fixed plates of different heights in different longitudinal channels by bolts, install the impact force sensor on the fixed plate, and fix the supporting plate on the top of the impact force sensor. When installing, first remove the first steel plate at the corresponding position, and fix the first steel plate back to its original position after installation;

[0047] (3) Deploy several cameras at the construction site to ensure that they can capture possible falling objects;

[0048] (4) Place the controller and display in a gathering place outside the construction site, connect the electrical components with wires, and connect them to the power supply;

[0049] (5) When an object passes through the through hole of the first steel plate and falls onto the supporting plate, the controller records the impact force data transmitted by the impact force sensor and the time when the object fell. Then, the controller converts the impact force data into a corresponding accident scene animation through the conversion and analysis unit, and analyzes which construction workers performed which construction operations that caused the object to fall based on the video acquisition information and the time information when the impact force sensor sent the signal.

[0050] (6) When workers gather in a gathering place, a safety education meeting is held. During the meeting: first, the specific circumstances of the falling object are reported, including the time of the falling object and the impact force data. The cause of the falling object is reported based on the video collection information, and the original video screen is played. Then, the converted accident scene animation is played through the display. Safety education is carried out in combination with the accident scene animation to promote workers to enhance their safety awareness.

[0051] Conventional safety education is conducted in the classroom through paper or video information, and some are conducted through simulated on-site devices. However, these safety educations are separated from the actual construction site and have no direct relevance to the workers' personal feelings and interests. Therefore, it is difficult for workers to have a profound personal experience, so it is difficult to stimulate the workers' subjective initiative. The present invention overcomes this defect by combining a security control method with a construction site. During the education process, the impact force data collected comes from the construction site where the workers personally participate. After converting the impact force data into an accident scene animation, the workers can intuitively understand that even a tiny falling object can cause irreparable accident injuries. Therefore, the workers' sensory and emotional experiences can be fully mobilized, and by combining education with the workers' personal interests, the workers can be stimulated to have a significant safety awareness. Since this safety awareness is autonomous rather than passively accepted, it can have a positive impact on construction safety.

[0052] Example 3:

[0053] Based on Example 2, this example discloses:

[0054] refer to Figure 1-5 As shown, in step (5), the conversion method of the accident scene animation is as follows: assuming that the impact force data occurs on a person, and simulating the degree of injury that the person may suffer based on the data through a preset program, and then calling the accident scene animation preset in the storage unit based on the simulation results. For example, if the head is smashed, internal head injuries, fainting, death on the spot, or being sent to the hospital, an animation can be pre-made based on the safety knowledge of falling objects from high altitudes and used in conjunction with the impact force data. Alternatively, an animation can be post-made based on the collected impact force data and input into the storage unit.

[0055] refer to Figure 1-5As shown, in the step (5), it is assumed that the impact force data occurs on a person, and the person is a worker, a pedestrian, an elderly person, a child, a person wearing a helmet, a person without a helmet, a pregnant woman or other injured person; the falling object that causes the impact force is concrete particles, steel nails, tools or other possible falling objects at the construction site, and different accident scene animations are displayed according to the different injured objects and the different possible falling objects.

[0056] refer to Figure 1-5 As shown, when falling objects occur in multiple longitudinal channels, the accident scene animation is converted according to the impact force data at different heights, and in step (6), the accident scene animation is combined with the impact force and injury degree at different heights to explain the workers' understanding and mastery of the knowledge of falling objects from high altitudes.

[0057] refer to Figure 1-5 As shown, in step (6), combined with the explanation of security knowledge, the person responsible for the falling object accident is criticized and educated, and the accident record is made. When the accident record of the same person reaches a preset number of times, the person responsible is subject to escalation treatment. Escalation treatment: such as suspension of work, fines or other penalties.
