Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to an early warning device for edge protection in building construction. Background Art

[0002] Edge protection devices, also known as edge protection systems or edge guardrails, are safety protection facilities used on the edges of buildings to prevent people or objects from falling. The specific forms of edge protection devices can include various forms of temporary guardrails, such as steel pipe guardrails, mesh guardrails, etc., as well as retaining walls built with various masonry materials. These devices usually have the functions of isolation, blocking and warning, which can effectively prevent people from falling and materials from falling, reduce accident losses and improve work efficiency.

[0003] Edge protection devices can not only be used for high-altitude edge protection, but also for separating vehicles and pedestrians. For example, when building security booths and toll booths, edge protection devices can be used to separate the construction site from the highway to prevent vehicles from mistakenly entering the construction site. At this time, the height difference between the two sides of the edge protection device is small, and it only serves as isolation and warning. When construction is carried out at these locations, the construction site is relatively open. If construction is carried out in the hot summer, it is very easy for workers to suffer from heatstroke. Because the construction site is open and there is no hiding place, workers often rest next to large vehicles when they rest, and even worse, take a nap at the bottom of the vehicle or under the bucket, which is very dangerous. If the vehicle is started without knowing it, it will cause serious safety accidents.

[0004] Traditional edge protection devices have a single function and cannot provide more protection for workers. Prolonged exposure in hot weather can easily cause heatstroke or sunburn. Additional awnings need to be installed for workers to use, which has low work efficiency and a single protective function.

[0005] Therefore, it is necessary to propose an early warning device for edge protection in building construction to solve the above problems. Utility Model Content

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention provides as Figures 1-8An early warning device for edge protection in building construction as shown, comprising a first support column 1 and a second support column 11. Installation feet 18 are fixedly installed at the bottom ends of the first support column 1 and the second support column 11. A triangular plate is used to reinforce between the installation feet 18 and the first support column 1. Both the first support column 1 and the second support column 11 are made of I-shaped steel. The first support column 1 and the second support column 11 are symmetrically arranged. Two symmetrically arranged first protective plates 2 are slidably clamped at the upper ends between the first support column 1 and the second support column 11. Partition plates 12 are fixedly installed in the middle of the sides of the first support column 1 and the second support column 11 that are close to each other. The two first protective plates 2 are respectively located on both sides of the partition plates 12. The first protective plate 2 includes a mesh plate 21. Sunshade cloths 23 are fixedly installed on the sides of the two mesh plates 21 that are close to each other. Two symmetrically arranged first sliding rods 22 are fixedly installed at the ends of both sides of the mesh plate 21 close to the first support column 1 and the second support column 11. Second grooves 17 are opened at the tops of the first support column 1 and the second support column 11. The width of the first groove 16 is equal to the diameter of the first sliding rod 22. First grooves 16 are opened at the positions of the first support column 1 and the second support column 11 close to the second grooves 17. Fixing components 3 are provided at the positions of the first support column 1 and the second support column 11 corresponding to the two first protective plates 2. The fixing components 3 are used to control the opening and closing of the second grooves 17. Two symmetrically arranged winding wheels 4 are fixedly installed at the tops of the first support column 1 and the second support column 11. A steel wire rope 41 is fixedly connected to the surface of the winding wheel 4. A torsion spring is provided inside the winding wheel 4, which can automatically wind the steel wire rope 41. One end of the steel wire rope 41 away from the winding wheel 4 is fixedly connected to one of the upper first sliding rods 22 respectively. A second protective plate 5 is fixedly installed at the lower end between the first support column 1 and the second support column 11. A reflective strip 6 is adhered to the second protective plate 5.

[0030] Edge protection devices, also known as edge protection systems or edge guardrails, are safety protection facilities used on the edges of buildings to prevent people or objects from falling. The specific forms of edge protection devices can include various forms of temporary guardrails, such as steel pipe guardrails, mesh guardrails, etc., as well as retaining walls built with various masonry materials. These devices usually have the functions of isolation, blocking and warning, which can effectively prevent people from falling and materials from falling, reduce accident losses, and improve work efficiency. Therefore, edge protection devices can not only be used for high-altitude edge protection, but also for separating vehicles and people, such as in building security booths and toll booths, etc. During construction, edge protection devices can be used to separate the construction site from the highway to prevent vehicles from mistakenly entering the construction site. At this time, the height difference between the two sides of the edge protection device is small, and it only serves as isolation and warning. When construction is carried out at these locations, the construction site is relatively open. If construction is carried out in the hot summer, it is very easy for workers to suffer from heatstroke. Because the construction site is open and there is no hiding place, workers often rest next to large vehicles when they rest, and even worse, take a nap at the bottom of the vehicle or under the bucket, which is very dangerous. If the vehicle is started without knowing it, it will cause serious safety accidents.

[0031] When the device is used for non-high-altitude installation, first use the ground nails to fix the installation feet 18 to the ground, then use the fixing component 3 to control the second slot 17 to open, rotate and push the first protective plate 2 upward, so that the two first sliding bars 22 above slide out from the inside of the second slot 17, and continue to push the first protective plate 2 so that the first protective plate 2 is horizontal. During this process, the winding wheel 4 releases the wire rope 41 to support the first protective plate 2, and the fixing component 3 can support the other end of the first protective plate 2 so that the first protective plate 2 forms a structure similar to a tarpaulin. Because a sunshade cloth 23 is fixedly installed on one side of the mesh plate 21, a rest area can be formed under the first protective plate 2, and workers can temporarily rest below. The remaining first protective plate 2 and second protective plate 5 can protect the workers and serve as a warning to the surrounding area. It should be noted that the location where the device is used as a sunshade cannot be at high altitude or at the edge of a dangerous area.

[0032] A plurality of fixing blocks 15 are fixedly installed at positions corresponding to the first support column 1 and the second support column 11 and the fixing component 3. The fixing component 3 includes a second sliding rod 31. The second sliding rod 31 is slidably clamped in the middle of the fixing block 15. A second stop rod 35 is integrally formed at the top end of the second sliding rod 31. A rotating plate 33 is rotatably installed at the upper end of the second sliding rod 31. A first stop rod 34 is fixedly installed on one side of the rotating plate 33. The second stop rod 35 is located on one side of the second groove body 17. The first stop rod 34 passes through the first groove body 16 and extends into the corresponding first support column 1 and the second support column 11. The inner walls of both sides at the upper end of the first groove body 16 are inclined. Clamping plates 13 are fixedly installed on both sides corresponding to the first support column 1 and the second support column 11 and the fixing component 3. A bent rod 32 is integrally formed at the bottom end of the second sliding rod 31. The bent rod 32 is placed inside the clamping plate 13. A lock body 14 is detachably installed on the clamping plate 13.

[0033] When the first protection plate 2 needs to be propped up, first remove the lock body 14, then rotate the bent rod 32 and pull it downward. At this time, the second sliding rod 31 drives the second stop rod 35 to descend. Then the second groove body 17 is opened at this time. The first stop rod 34 is blocked by the inner wall of the first groove body 16 and rotates. The first stop rod 34 and the rotating plate 33 rotate to fit the side surface of the second sliding rod 31. Then prop up the first protection plate 2. At this time, the two lower first sliding rods 22 are located at the inner top ends of the first support column 1 and the second support column 11. At this time, push the bent rod 32 to re-clamp the bent rod 32 inside the clamping plate 13. At this time, the second stop rod 35 closes the second groove body 17 again. At the same time, the first stop rod 34 is blocked by the upper side wall of the first groove body 16 and then returns to a state perpendicular to the second sliding rod 31 again. At this time, two of the first sliding rods 22 are supported above the first stop rod 34. Thus, the first protection plate 2 forms a stable support. If the first protection plate 2 needs to be retracted, only need to pull the second sliding rod 31 again. Driven by gravity, the two lower first sliding rods 22 will slide along the top ends of the first support column 1 and the second support column 11 to the inner bottom ends. Because of the restraint of the steel wire rope 41, the two upper first sliding rods 22 will pass through the second groove body 17 and re-enter the first support column 1 and the second support column 11. Thus, the retraction is realized. Both opening and retraction are relatively convenient.

[0034] When the device is installed at the edge of a dangerous position, the safety officer at the construction site should use the lock body 14 to lock the clamping plate 13 to prevent workers from operating illegally to open the first protection plate 2. Only when the device is in a safe environment can the sunshade function be used.

[0035] When construction is carried out in an open area, such as building a security booth and a toll booth by the roadside, at this time, the edge protection device mostly serves as a warning to nearby vehicles not to approach this area. Workers can open both of the first protection plates 2. At this time, the device can be used as a temporary entrance and exit, facilitating the transportation of materials and using the device as the access to the construction site.

[0036] Working principle: First, use ground nails to fix the mounting feet 18 on the ground, and then use the fixing component 3 to control the opening of the second groove 17. Rotate and push up the first protection plate 2 so that the two upper first sliding rods 22 slide out from the inside of the second groove 17. Continuously push the first protection plate 2 until the first protection plate 2 is in a horizontal state. During this process, the wire rope 41 is released by the winding wheel 4 to support the first protection plate 2. The fixing component 3 can support the other end of the first protection plate 2, so that the first protection plate 2 forms a structure similar to a tarpaulin. Since a sunshade cloth 23 is fixedly installed on one side of the mesh plate 21, a rest area can be formed below the first protection plate 2.

[0037] When it is necessary to lift the first protection plate 2, first remove the lock body 14, then rotate the bent rod 32 and pull it downwards. At this time, the second sliding rod 31 drives the second blocking rod 35 to descend, and then the second groove 17 is opened. The first blocking rod 34 is blocked by the inner wall of the first groove 16 and rotates. The first blocking rod 34 and the rotating plate 33 rotate to fit the side surface of the second sliding rod 31. Then lift the first protection plate 2. At this time, the two lower first sliding rods 22 are located at the inner top ends of the first support column 1 and the second support column 11. Then push the bent rod 32 to reinsert the bent rod 32 into the inside of the clamping plate 13. At this time, the second blocking rod 35 closes the second groove 17 again. At the same time, the first blocking rod 34 is blocked by the upper side wall of the first groove 16 and then returns to a state perpendicular to the second sliding rod 31 again. At this time, two of the first sliding rods 22 are supported above the first blocking rod 34, so that the first protection plate 2 forms a stable support. If it is necessary to retract the first protection plate 2, only need to pull the second sliding rod 31 again. Driven by gravity, the two lower first sliding rods 22 will slide along the top ends of the first support column 1 and the second support column 11 to the inner bottom ends. Because of the restraint of the wire rope 41, the two upper first sliding rods 22 will pass through the second groove 17 and re-enter the inside of the first support column 1 and the second support column 11, thus realizing the retraction.

[0038] Workers can open both of the first protection plates 2. At this time, the device can be used as a temporary entrance and exit, facilitating the transportation of materials and using the device as the access to the construction site.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
