Specific implementation manner

[0018] 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.

[0019] Please refer to Figures 1 to 10 , this embodiment provides a guardrail reinforcement device for building construction, including: guardrail body 1, base 2, support block 3, placement groove 4, support leg 5, guardrail net rack 6, rotating member, moving member and connecting member.

[0020] In this embodiment: Through the operation of the rotating member, the moving member and the connecting member have a certain self-locking property, which helps the components to have excellent stability after operation. The rotating member drives the moving member to operate, so that the guardrail net rack 6 forms a conical shape in the middle in front of the guardrail body 1, and has a buffering form and self-locking ability. When not in use, such as during transportation and storage, it can be folded to reduce the occupied space, which is convenient for transportation and storage. The change of its conical shape can divert and cut the wind, and the purpose of guiding the wind obliquely, reducing the direct impact of the wind on the guardrail body 1 and reducing the risk of shaking, so as to achieve the reinforcement purpose. This method also has the purpose of elastic sliding and telescoping, so that the angle between the two guardrail net racks 6 continuously changes, further buffering the wind force, changing the angle of the two guardrail net racks 6 to disperse the wind pressure, and improving the stability of the guardrail body 1; The rotating component synchronously drives the connecting component to operate, so as to drive the two supporting blocks 3 to extend, further increasing the contact area between the base 2 and the ground. The extended supporting blocks 3 serve the purpose of acting as auxiliary wheels for the bicycle, further improving the anti-shaking and stability capabilities of the base 2, and further enhancing the stability of the guardrail body 1. When not in use, the two supporting blocks 3 retract into the base 2, serving the purpose of storage, reducing the large occupied area during transportation and transit. Moreover, since this method uses screw rotation to extend and retract the supporting blocks 3, it also has a certain self-locking function.

[0021] The guardrail reinforcement device for building construction further includes a locking component.

[0022] In this embodiment: Through the operation of the locking component, the guardrail body 1 can be stably locked on this device. This device can implement all-round locking of the guardrail body 1. By horizontally locking the supporting feet 5 and vertically pressing against the guardrail body 1, stable fixation is achieved, avoiding movement and shaking. Compared with the method of only locking the supporting feet, this multi-directional locking design enhances the stability of the guardrail and can adapt to guardrail right angles of various heights and specifications, improving practicality. After locking, this device can enhance the protection and wind resistance capabilities of the guardrail body 1, having an excellent reinforcement effect. The overall operation has a convenient effect, and without multiple complex operations, excellent locking of the guardrail body 1 can be achieved.

[0023] Please refer to Figures 1 - 7 , in this embodiment, the rotating component includes: A rotation driving part 40. An installation shell 7 is fixedly connected to the upper surface of the base 2. The rotation driving part 40 is arranged on the installation shell 7. The output part at the lower surface of the rotation driving part 40 is fixedly connected to a rotating shaft 8. A worm 9 is fixedly connected to the outer surface of the rotating shaft 8. A first screw 10 is rotatably connected to the inner wall of the installation shell 7 around a fixed axis. A worm gear 11 is fixedly connected to the outer surface of the first screw 10. The worm gear 11 is meshed and connected with the worm 9.

[0024] In this embodiment: The rotation driving part 40 can be installed on the top of the installation shell 7 in the form of a motor, or can also be in the form of manual twisting. Through the rotation of the rotation driving part 40, the rotating shaft 8 and the worm 9 are driven to rotate. Under meshing transmission, the worm gear 11 is driven to rotate, so that the first screw 10 rotates. Since the transmission between the worm 9 and the worm gear 11 has self-locking property, through the operation of the rotation driving part 40, a certain self-locking force can be provided for subsequent mechanisms or components, and thus has an excellent reinforcement effect.

[0025] Please refer to Figures 1 - 4 and Figure 7 , in this embodiment, the moving component includes: The limiting member 13 is fixedly connected to the upper surface of the base 2 at the lower surface thereof. The threaded portion of the first screw rod 10 is threadedly connected to the moving block 12. The outer surface of the moving block 12 is slidably connected to the inner side of the limiting member 13. A sleeve block 35 is slidably sleeved at the end of the moving block 12. A first spring is fixedly connected to the opposite sides of the inner wall of the moving block 12 and the sleeve block 35. The connecting shaft 14 rotatably connects the two guard net frames 6. An opening one through which the connecting shaft 14 passes and is fixedly rotationally connected thereto is formed at the end of the sleeve block 35. A plug rod 15 is fixedly connected to the lower surface of the guard net frame 6. A sliding groove 16 into which the plug rod 15 extends and slides is formed on the upper surface of the base 2. The sliding groove 16 is formed along the length direction of the base 2.

[0026] In this embodiment: By rotating the first screw rod 10, under the screw drive and the sliding restriction of the limiting member 13, the moving block 12 and the sleeve block 35 are driven to move away from the worm gear 11, so as to drive the connecting shaft 14 to move synchronously. And because of the connection of the connecting shaft 14, the two guard net frames 6 have the characteristic of being hinged. When the hinge point moves, the two guard net frames 6 will arch forward to form a shape similar to a triangle and a cone. And the plug rod 15 slides in the sliding groove 16 to adapt to the deflection of the guard net frame 6. And finally, the two guard net frames 6 Figure 1 Starting from the initial state, move to the state where the two guard net frames 6 arch, so as to realize the change of the angle between the two guard net frames 6. This method has the purpose of folding. When not in use and during transportation, it can reduce the occupied area, which is convenient for transportation and storage. This method can achieve excellent reinforcement. Through this conical shape, it can reduce the situation where the wind directly acts on the guardrail body 1 to a certain extent. The wind is shunted and cut through the conical shape and multiple mesh holes on the guard net frame 6. Overall, it can achieve the purpose of obliquely guiding the wind blowing horizontally onto the guardrail body 1, which helps to reduce the force of the wind directly acting on the guardrail body 1, thereby reducing the situation of the guardrail body 1 shaking and being unstable due to the action of the wind, and thus achieving the purpose of reinforcement. And because the guardrail body 1 is mostly designed with hollow or open structures for ventilation and drainage purposes, in order to avoid blocking, the form of the guard net frame 6 is used for wind guidance and shunting to avoid affecting the performance of the guardrail body 1 itself. This method can also achieve the purpose of buffering due to the elastic sliding between the sleeve block 35 and the moving block 12. Through the conical shape, it can achieve the purpose of shunting and guiding the wind, and through the elastic sliding, it can further achieve the purpose of wind buffering. When the wind acts on the two guard net frames 6, it can make the angle between the two guard net frames 6 change continuously to further buffer this part of the wind force, so as to further improve the stability of the guardrail body 1.

[0027] Please refer to Figures 1 - 7 , in this embodiment, the connecting component includes: A first coupling shaft 17, the rotating shaft 8 penetrates into the interior of the base 2 and is fixedly rotationally connected to the base 2. The lower end of the rotating shaft 8 is drivingly connected to the outer surface of the first coupling shaft 17 through a first bevel gear transmission mechanism 18. A second coupling shaft 36 is fixedly rotationally connected to the inner wall of the base 2 through a support. The outer surface of the second coupling shaft 36 is drivingly connected to the outer surface of the first coupling shaft 17 through a pulley transmission mechanism 19; Two brackets 20, the lower surface of the bracket 20 is fixedly connected to the inner wall of the base 2. The upper end of the bracket 20 is fixedly rotationally connected to a second screw 21. A first bevel gear 22 is fixedly connected to the opposite sides of the two second screws 21. A second bevel gear 23 is fixedly connected to the outer surface of the second coupling shaft 36. The tooth grooves of the two first bevel gears 22 are meshed with the tooth grooves of the second bevel gear 23. An internal thread groove for the second screw 21 to penetrate and be threadedly connected therewith is provided on the side surface of the support block 3.

[0028] In this embodiment: By rotating the rotating shaft 8, under the transmission of the first bevel gear transmission mechanism 18, the first coupling shaft 17 is driven to rotate, and under the transmission of the pulley transmission mechanism 19, the second coupling shaft 36 and the second bevel gear 23 are driven, so that the first bevel gear 22 and the second screw 21 rotate. And due to the sliding restriction of the base 2 on the support block 3 and the thread transmission, the two support blocks 3 move in the same direction and tilt away from each other synchronously, so that the two support blocks 3 extend out, further increasing the contact area between the base 2 and the ground. And the extended support blocks 3 serve the purpose of an auxiliary wheel for the bicycle, further improving the anti-shaking and stability of the base 2, thereby further enhancing the stability of the guardrail body 1. And when not in use, the two support blocks 3 are retracted into the base 2, thus achieving the purpose of storage, so as to reduce the large occupied area during transportation and transfer. And this method has a certain self-locking property because the support block 3 is telescoped by means of screw rotation.

[0029] Please refer to Figures 1 - 4 、 Figure 8 and Figure 10 , in this embodiment, the locking component includes a vertical component and a horizontal component; The vertical component includes: Two first elastic telescopic members 24, the lower ends of the first elastic telescopic members 24 are fixedly connected to the upper surface of the base 2 , the upper ends of the first elastic telescopic members 24 are arranged in an L shape, and a pressing block 25 is slidably connected to the upper ends of the first elastic telescopic members 24; A screw rod three 37 is slidably connected to the upper surface of the briquette 25. The upper end of the screw rod three 37 is fixedly connected to a handle part 38. An annular groove body is formed inside the briquette 25. An annular block 33 is fixedly connected to the outer surface of the screw rod three 37. The annular block 33 is located inside the annular groove body. A plurality of threaded sleeves 34 are arranged on the inner wall of the elastic telescopic member one 24. The threaded sleeves 34 are arranged along the transverse part of the L-shaped end of the elastic telescopic member one 24.

[0030] The transverse member includes: Two elastic telescopic members two 26. The lower surface of the elastic telescopic member two 26 is fixedly connected to the inner wall of the base 2. The telescopic part at the upper end of the elastic telescopic member two 26 is fixedly connected to a support block 27. The support block 27 is located inside the placement groove 4. The placement groove 4 is provided with a notch for the support block 27 to slide. The upper surface of the support block 27 is used to contact the support leg 5. Two groups of clamping blocks 28. The clamping blocks 28 correspond to the support legs 5 at the placement groove 4. The number of each group of clamping blocks 28 is two, which are respectively located on both sides of the support leg 5. An opening two for the clamping blocks 28 to pass through and be slidably connected therewith is formed in the inner wall of the base 2. An elastic telescopic member three 29 is fixedly connected to the relative side of the clamping block 28 and the inner wall of the base 2. Two groups of rotating rods 30 are rotatably connected to the inner wall of the base 2 by a fixed shaft. The number of each group of rotating rods 30 is two. A pressing plate 31 is fixedly connected to the outer surface of the rotating rod 30. A torsion spring 32 is fixedly connected to the relative side of the pressing plate 31 and the inner wall of the base 2. The torsion spring 32 is sleeved on the rotating rod 30. The lower end of the pressing plate 31 is used to press against the lower surface of the support block 27, and the upper end of the pressing plate 31 is used to press against the side surface of the clamping block 28.

[0031] In this embodiment: First, place the guardrail body 1 on the placement groove 4. At this time, pull the upper end of the elastic telescopic member one 24 to drive the elastic telescopic member one 24 to move vertically to adapt to guardrail bodies 1 of different heights. Then, drive the briquette 25 to extend by means of the handle part 38. Thus, under the elastic telescopic relationship of the elastic telescopic member one 24, the lower surface of the extended briquette 25 abuts against the upper surface of the guardrail body 1, thereby giving the guardrail body 1 a vertical pressing force. When it is necessary to remove the briquette 25, only need to lift the handle part 38 and drive the handle part 38 to move outwards, and then can drive the briquette 25 to continuously extend. And when it extends to a sufficient length, press the handle part 38 downwards, so that the third screw 37 is inserted downwards into the threaded sleeve 34, and twist the handle part 38 to make the third screw 37 rotate, so as to screw into the threaded sleeve 34. A scale or other prompt method can be set at the upper end of the first elastic telescopic part 24 to indicate whether the third screw 37 is directly opposite to the threaded sleeve 34. This method only needs to drive the handle part 38 to realize the height change of the vertical part and the extension of the vertical part and place it on the guardrail body 1. It has excellent convenience and does not require multiple operations. A single person can operate to realize the overall operation. And it also has an excellent locking effect through the threaded locking method, and the practicability is better.

[0032] With the downward acting force applied to the guardrail body 1, the support feet 5 of the guardrail body 1 will move downwards, thereby pressing the support block 27 downwards and pressing the second elastic telescopic part 26. And the elastic force of the second elastic telescopic part 26 is not enough to offset the gravity of the guardrail body 1 and the pressure given to the guardrail body 1 by the first elastic telescopic part 24. Therefore, the second elastic telescopic part 26 shrinks. The downward moving support block 27 will abut against the lower end of the pressing plate 31, so that the pressing plate 31 deflects with the rotating rod 30 as the center, so that the upper end of the pressing plate 31 deflects correspondingly, so that the upper end of the pressing plate 31 abuts against the clamping block 28 and moves towards the support foot 5 for approaching movement, and finally the two clamping blocks 28 synchronously clamp the support foot 5 inwardly in the horizontal direction; This method can achieve the purpose of locking the guardrail body 1 in all directions, so that the guardrail body 1 is locked on this device, and the purpose of strengthening the guardrail body 1 can be achieved under the action of this device. It can apply a horizontal locking force to the support feet 5 of the guardrail body 1 and a vertical pressing force to the guardrail body 1 to achieve the effect of locking and stabilizing in all directions. Different from the method of only locking the support feet 5, this multi-directional locking method helps the guardrail body 1 to be stable on this device, and it is not easy to have unstable situations such as movement and shaking. And it can be used to adapt to guardrails of various heights to a certain extent. And because a relatively large horizontal part is provided, it can be used to lock and adapt to support feet 5 of various specifications of guardrails to a certain extent to improve the practicability of this device. Furthermore, after the guardrail body 1 is locked on this device, the protection and wind resistance ability of the guardrail body 1 can be improved based on this device, and it can avoid unstable situations such as shaking and moving of the guardrail body 1, and has an excellent strengthening effect.

[0033] Please refer to Figures 1 - 6 In this embodiment, the base 2 is trapezoidally arranged, and anti-slip patterns are provided on the lower surface of the base 2.

[0034] In this embodiment: First, the base 2 is set in a trapezoidal shape with a larger bottom and a smaller top. After the base 2 is connected to the guardrail body 1, it can directionally increase the contact area between the guardrail body 1 and the ground, avoiding the situation that the guardrail body 1 topples due to external forces during use, thereby improving the reinforcement and stability effects of the guardrail body 1. Moreover, the trapezoidal shape with a larger bottom and a smaller top can have a certain wind guiding effect in a certain degree through the inclination of the trapezoid, which can improve the wind resistance performance of the entire guardrail to enhance the reinforcement and stability of this device. Therefore, it further improves the reinforcement stability of the guardrail, and the design of anti-slip lines can increase the contact friction between the base 2 and the ground to improve the contact stability, avoiding the situation that the guardrail body 1 easily moves due to external forces to enhance the reinforcement ability.
