Abstract
Description
Technical Field
[0001] The invention relates to the technical field of building construction, and in particular to safety protection equipment for exterior wall construction of high-rise buildings. Background Art
[0002] Building exterior wall construction refers to various construction engineering activities carried out on the external wall structure of a building, aiming to complete the construction and decoration of the building's exterior walls, protect the building structure, provide a beautiful appearance, and meet the functional and design requirements of the building. When carrying out construction, it is often necessary to set up a protective net around the building to protect the construction workers.
[0003] The protective net is a new type of building security product that provides safety protection such as falling objects. In the current high-rise building construction process, it is often necessary to set up a protective net around the building to catch people or objects that may fall from the building. The building protective net is used in building construction, which can not only effectively prevent workers from falling, but also can prevent gravel or tools from falling during the construction process, greatly increasing the safety of the construction process.
[0004] However, the existing protective net can prevent construction workers from falling by fixing the supporting steel pipe on the wall with both ends of the protective net fixed on the surface of the supporting steel pipe. However, once a construction worker falls, when the person falls on the protective net, the human body comes into direct contact with the protective net, and the protective net itself lacks mobility, causing damage to the human body, especially the internal organs, under the action of the falling acceleration; more importantly, when an object falls on the protective net, it has a large impact force on the protective net, which can easily damage the protective net and make the protection ineffective. At the same time, when the protective net is impacted, the impact force will further act on the connection between the supporting steel pipe and the wall, causing structural damage to the connection between the wall and the steel pipe.

The drawings described in the present invention are only schematic diagrams of the structure.
[0026] The present invention provides a high-rise building exterior wall construction safety protection device, such as Figure 1-2As shown, it includes a pair of first supporting steel rods 1, a pair of first supporting steel rods 1 are vertically fixedly installed on the construction wall, the bottom of the pair of first supporting steel rods 1 are fixedly connected with a horizontally arranged second supporting steel rod 2, a first protective net 3 is fixedly installed between the pair of second supporting steel rods 2, the top of the pair of second supporting steel rods 2 are hinged with an inclined third supporting steel rod 4, a second protective net 5 is fixedly installed between the pair of third supporting steel rods 4, a buffer structure 6 is provided in the first supporting steel rod 1, and the buffer structure 6 includes a first steel rope 61, the first steel rope 61 is arranged in the first supporting steel rod 1, one end of the first steel rope 61 is fixedly connected to the side of the third supporting steel rod 4 away from the first supporting steel rod 1, and a traction block 62 is slidably arranged in the first supporting steel rod 1, and a buffer spring 63 is fixedly connected to the top of the traction block 62, one end of the buffer spring 63 is fixedly connected to the traction block 62, and the other end is fixedly connected to the inner top of the first supporting steel rod 1, and the mesh aperture of the second protective net 5 is larger than the mesh aperture of the first protective net 3.
[0027] The present invention provides a safety protection device for the construction of the exterior wall of a high-rise building. In the present invention, the third support steel rod 4 is hinged to the second support steel rod 2 through a hinge 13. In the original state, there is an angle difference between the third support steel rod 4 and the first support steel rod 1. When the construction personnel fall on the second protection net 5, the third support steel rod 4 will be pressed down, and the force acting on the third support steel rod 4 will be buffered by the buffer structure 6 and the arc compression spring 15. Double-layer protection is performed by the first protection net 4 and the second protection net 5. The buffer structure 6 buffers the second protection net to prevent the impact force of the construction personnel falling onto the protection net from damaging the protection net and rendering the protection ineffective; and under the action of the buffer component 6, the human body is protected to prevent the human body from not being well buffered when falling and causing damage to the human body, especially the internal organs.
[0028] At the same time, it is prevented that the force directly acts on the connection between the supporting steel pipe and the wall to loosen the connection, resulting in weak protection and potential safety hazards. In addition, there is a height difference between the second protective net 5 and the first protective net 4 in the initial state. When a falling person falls on the second protective net 5, the buffer component 6 is driven at the same time for buffering, and the second protective net 5 descends to minimize the reaction force on the falling person, thereby effectively protecting the falling person and preventing the excessive impact force generated during the fall from directly acting on the human body and causing impact on the internal organs of the construction workers.
[0029] In the present invention, the mesh diameter of the second protective net 5 is larger than the mesh diameter of the first protective net 3, and fallen objects such as gravel will fall onto the first protective net 3 through the second protective net 5. When a construction worker accidentally falls, he will fall on the second protective net 5, and the propulsion plate 8 provided on the first protective net 3 will be driven by the buffer structure 6. The propulsion plate 8 will push the gravel that falls from the first protective net 3 into the collection box 16 for storage, so as to prevent the gravel that falls from the first protective net 3 from injuring the falling construction worker and causing secondary injury.
[0030] In the present invention, in the initial state, the third support steel rod 4 is hinged to the second support steel rod 2 by the hinge 13, and there is an angle difference between the third support steel rod 4 and the second support steel rod 2. Under normal protection conditions, the fallen gravel will pass through the second protection net 5 and fall on the first protection net 3. When the construction personnel fall accidentally, they will first fall on the second protection net 5. With the impact of the second protection net 5, the third support steel rod 4 will move downward and pull the first steel rope 61 set on the top of the third support steel rod 4. Through the conversion of the first fixed pulley 10, the traction block 62 set in the first support steel rod 1 will be pulled, so that the traction block 62 moves up and the buffer spring 63 is squeezed. In this process, the construction personnel who fall accidentally are protected by the first protection net 3, and the impact force generated during the fall is reduced by the buffer spring 63, thereby avoiding excessive force causing the connection between the support steel pipe and the wall to loosen.
[0031] In the present invention, the length of the first protection net 3 and the second protection net 5 is 10m and the width is 5m, so as to facilitate reasonable installation and protection according to actual conditions.
[0032] When the third supporting steel rod 4 is flush with the second supporting steel rod 2, the construction workers who fall on the second protective net 5 will come into contact with the first protective net 3 again. The double protection of the first protective net 3 and the second protective net 5 can better protect the construction workers who fall accidentally. The double support of the first protective net 3 and the second protective net 5 increases the guarantee of safety protection. In the process of the first protective net 3 changing from inclined to horizontal, the buffer component 6 gradually buffers and eliminates the acceleration generated when the human body falls, avoiding excessive impact force from directly impacting the internal organs of the falling person.
[0033] Preferably, Figure 1 to Figure 4As shown, a pair of second supporting steel rods 2 are provided with a pair of slide grooves 7 along their length direction, and sliders 9 are slidably arranged in the pair of slide grooves 7. A push plate 8 is provided between the pair of second supporting steel rods 2, and the slider 9 is fixedly connected to the push plate 8 through a connecting rod. An inclined slope is provided on the side of the push plate 8 close to the first supporting steel rod 1, and in the original state, the bottom of the push plate 8 is tightly attached to the first protective net 3 and lifts up the first protective net 3. A collecting box 16 is provided at the bottom of the connection between the second supporting steel rod 2 and the first supporting steel rod 1, and the top of the collecting box 16 is opened, and when the third supporting steel rod 4 is parallel to the second supporting steel rod 2, the push plate 8 is tightly attached to the collecting box 16.
[0034] In the present invention, a slide groove 7 is provided on the second supporting steel rod 2, and the slide groove 7 supports the set slider 9. Because the fallen gravel in the present invention is on the first protective net 3, and when the construction workers accidentally fall, the gravel on the first protective net 3 will cause secondary injuries to the falling construction workers. Therefore, it is necessary to clean up the gravel on the first protective net 3 to protect the construction workers and prevent secondary injuries to the construction workers. The present invention connects the traction block 62 with the slider 9 through the second steel rope 11, and the second steel rope 11 is wound around the second fixed pulley 12. When the construction workers accidentally fall off the first protective net 3, the first buffer protection will be performed, and the buffer structure 6 will timely drive the traction block 62 to move up. As the traction block 62 moves up, the set second steel rope 11 will be The second steel rope 11 is pulled to pull the slider 9 on the second supporting steel rod 2, thereby pulling the propulsion plate 8 on the slider 9 toward the first supporting steel rod 1. Because the propulsion plate 8 is provided with an inclined slope on the side close to the first supporting steel rod 1, and the bottom of the propulsion plate 8 is in close contact with the first protective net 3 in the original state, the protruding propulsion plate 8 caused by the pulling of the second steel rope 11 will cause the first protective net 3 to have an inclined slope, thereby causing the gravel retained on the first protective net 3 to move toward the first supporting steel rod 1, and when the third supporting steel rod 4 is flush with the second supporting steel rod 2, the propulsion plate 8 can promptly push the gravel on the first protective net 3 into the collecting box 16 for collection.
[0035] The present invention reasonably utilizes the impact force generated when the construction workers fall. On the one hand, the impact force of the fall is buffered by the buffer structure 6. On the other hand, the buffer structure 6 simultaneously drives the propulsion plate 8 during buffering, so as to clean up the gravel on the first protective net 3 in time. The design is reasonable, the use is convenient, and it has strong promotion potential.
[0036] Preferably, Figure 3As shown, a first fixed pulley 10 is fixedly provided on the top of the first supporting steel rod 1, a first steel rope 61 is wound around the first fixed pulley 10, a second steel rope 11 is fixedly connected to the bottom of the traction block 62, one end of the second steel rope 11 is fixedly connected to the slider 9, a second fixed pulley 12 is provided in the first supporting steel rod 1, and the second steel rope 11 is wound around the second fixed pulley 12.
[0037] In the present invention, the first supporting steel rod 1 supports the first fixed pulley 10 and the second fixed pulley 12. The first fixed pulley 10 is used to assist the pulling of the first steel rope 61 and change the moving angle of the first steel rope 61. The second fixed pulley 12 is used to assist the pulling of the second steel rope 11 and change the moving angle of the second steel rope 11, so as to reasonably connect the impact force generated when the construction workers fall with the buffer structure 6 and the thrust plate 8.
[0038] Preferably, Figure 1-2 As shown, the second supporting steel rod 2 is connected to the first supporting steel rod 1 by a hinge 13, and the hinge 13 includes a pair of fixed blocks 131, and the pair of fixed blocks 131 are respectively fixedly connected to the pair of second supporting steel rods 2. A placement groove 132 is opened on the top of the pair of fixed blocks 131, and a rotating rod 133 is rotatably inserted in the placement groove 132. One end of the third supporting steel rod 4 is fixedly sleeved on the rotating rod 133, and when the third supporting steel rod 4 is flush with the second supporting steel rod 2, there is a gap between them in the vertical direction. Considering that in the interval where the second protective net 5 is displaced, the propulsion plate 8 pushes the stones dropped from the first protective net 4, when the third supporting steel rod 4 is flush with the second supporting steel rod 2, there is a gap between them in the vertical direction, which can effectively prevent the stones pushed by the propulsion plate from injuring the construction personnel in the interval where the second protective net 5 is displaced.
[0039] In the present invention, the third supporting steel rod 4 is hinged to the second supporting steel rod 2 by the hinge 13, the second supporting steel rod 2 supports the set fixed block 131, a rotating rod 133 is rotatably set in the fixed block 131, the third supporting steel rod 4 is fixedly sleeved on the rotating rod 133, when the construction personnel accidentally fall on the second protective net 5, the impact force will impact the third supporting steel rod 4, and the third supporting steel rod 4 will rotate through the set rotating rod 133, and finally the third supporting steel rod 4 will be flush with the second supporting steel rod 2, and double protection and double guarantee are performed by the first protective net 3 and the second protective net 5, so as to protect the falling construction personnel, improve the safety performance of the device, and have strong popularization.
[0040] Preferably, Figure 1 to Figure 3As shown, the top of the traction block 62 is fixedly connected to a vertically arranged telescopic rod 14, the first steel rope 61 passes through the telescopic rod 14 and is placed inside the telescopic rod 14, the top of the telescopic rod 14 is fixedly connected to the inner side of the first supporting steel rod 1, the buffer spring 63 is sleeved on the outer side of the telescopic rod 14, and an arc compression spring 15 is fixedly connected between the second supporting steel rod 2 and the first supporting steel rod 1, and the arc compression spring 15 is located at the hinge 13.
[0041] In the present invention, a telescopic rod 14 is arranged on the top of the traction block 62, so that the first steel rope 61 passes through the telescopic rod 14, and the arranged telescopic rod 14 plays a guiding role in the movement of the traction block 62, so that the traction block 62 can move stably in the first supporting steel rod 1, and an arc compression spring 15 is arranged between the second supporting steel rod 2 and the first supporting steel rod 1. The arc compression spring 15 and the buffer spring 63 are used to doubly buffer the impact force generated when the construction personnel fall, so as to avoid the impact force directly acting on the connection between the second supporting steel rod 2 and the first supporting steel rod 1, so as to have higher safety performance, and protect the first supporting steel rod 1 and the second supporting steel rod 2 to prevent the connection from loosening, thereby further enhancing the reliability of the device, increasing the protection effect, and ensuring the safety of the construction personnel.
[0042] Preferably, Figure 1 to Figure 5 As shown, a collecting box 16 is provided at the bottom of the connection between the second supporting steel rod 2 and the first supporting steel rod 1, and the top of the collecting box 16 is opened, and when the third supporting steel rod 4 is parallel to the second supporting steel rod 2, the pushing plate 8 is in close contact with the collecting box 16, and a third steel rope 17 is fixedly provided on the side of the first supporting steel rod 1 close to the second supporting steel rod 2, and a pulling handle 18 is fixedly connected to the bottom of the third steel rope 17, and an arc-shaped flexible pad 19 is fixedly connected to the top of the pushing plate 8.
[0043] In the present invention, a collecting box 16 is provided at the bottom of the connection between the second supporting steel rod 2 and the first supporting steel rod 1, which is used to store the crushed stones on the first protective net 3 pushed by the propulsion plate 8, and when the third supporting steel rod 4 is parallel to the second supporting steel rod 2, the propulsion plate 8 is in close contact with the collecting box 16, and there is a fixed moving distance between the movement of the propulsion plate 8 and the movement of the third supporting steel rod 4. When the third supporting steel rod 4 is parallel to the second supporting steel rod 2, the propulsion plate 8 has collected the stones dropped from the first protective net 3 in time. The rod 1 supports the third steel rope 17, and the third steel rope 17 supports the pulling handle 18. After passing through the buffering protection of the first protective net 3 and the second protective net 5, the construction personnel climb to the connection between the second supporting steel rod 2 and the first supporting steel rod 1, hold the pulling handle 18 tightly, stand up under the traction of the third steel rope 17, and enter the construction area. They can leave the suspended area in time to avoid the occurrence of uncontrollable factors. An arc-shaped flexible pad 19 is fixedly connected to the top of the propulsion plate 8 to prevent the top edges and corners of the propulsion plate 8 from causing harm to the construction personnel.

[0046] When a construction worker falls accidentally, he will first fall on the second protective net 5. With the impact of the second protective net 5, the third supporting steel rod 4 will move downward and pull the first steel rope 61 set on the top of the third supporting steel rod 4. Through the conversion of the first fixed pulley 10, the traction block 62 set in the first supporting steel rod 1 will be pulled, so that the traction block 62 moves upward and the buffer spring 63 is squeezed. In addition, an arc compression spring 15 is set between the second supporting steel rod 2 and the first supporting steel rod 1. The arc compression spring 15 and the buffer spring 63 are used to doubly buffer the impact force generated when the construction worker falls.
[0047] As the traction block 62 moves upward, the second steel rope 11 will be pulled. Under the traction of the second steel rope 11, the slider 9 will slide on the second supporting steel rod 2, thereby pulling the propulsion plate 8 on the slider 9 toward the first supporting steel rod 1. Because the propulsion plate 8 is provided with an inclined slope on the side close to the first supporting steel rod 1, and the bottom of the propulsion plate 8 is in close contact with the first protective net 3 in the original state, the protruding propulsion plate 8 with the pulling of the second steel rope 11 will cause the first protective net 3 to have an inclined slope, thereby causing the gravel retained on the first protective net 3 to move toward the first supporting steel rod 1, and when the third supporting steel rod 4 is flush with the second supporting steel rod 2, the propulsion plate 8 can promptly push the gravel on the first protective net 3 into the collection box 16 for collection, so as to prevent the gravel falling from the first protective net 3 from knocking and injuring the falling construction workers and causing secondary injuries.
