Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a construction fence. Background Art

[0002] Building construction refers to production activities during the implementation stage of engineering construction. It is the construction process of various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where construction work takes place is called "building construction site" or "construction site", also called construction site.

[0003] Construction is a technically complex production process, which requires construction workers to use their intelligence and creativity to apply theories of materials, mechanics, structure, and technology to solve technical problems that arise in construction and ensure project quality and construction safety. This construction process is carried out in a limited time and a certain space with the operation of multiple types of workers, the supply of hundreds of materials, and the operation of various mechanical equipment. Therefore, scientific and advanced organizational management measures and the use of advanced construction technology are necessary to successfully complete this production process. This process is also a highly economical process, which will consume a lot of manpower, material and financial resources during construction. Therefore, it is required to consider the economic benefits at all times during the construction process and take measures to reduce costs. During the construction process, people's focus is always on project quality, safety (including environmental protection), progress and cost.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: a fence is set up outside the construction site to ensure the safety of passers-by and prevent passers-by from mistakenly entering the construction site, and to ensure that materials at the construction site will not be easily stolen and cause property losses. However, the existing fence structure is fixed and has a low height. It can still be climbed over, and its safety is low. If the height of the fence is increased, it will be inconvenient to transport, reducing the flexibility and practicality of the fence. Utility Model Content

[0005] In order to improve the safety of the fence, protect the materials on the construction site from being stolen, and avoid the burden on the transportation and handling of the fence, the present application provides a construction fence.

DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-4 This application is described in further detail.

[0022] The present application embodiment discloses a construction fence. Figure 1-Figure 4 As shown, a construction fence includes a bottom plate 1, a motor 2 is fixedly connected inside the bottom plate 1, an output shaft 3 is rotatably connected to the left side of the motor 2, three bases 4 are fixedly connected to the inner bottom wall of the bottom plate 1, the outer circumferential surface of the output shaft 3 is rotatably plugged into the inside of the base 4, the inner diameter of the plug-in portion of the output shaft 3 and the base 4 is smaller than the outer diameter of the output shaft 3, the output shaft 3 is supported and reinforced, and the stability of the movement of the output shaft 3 is increased;

[0023] Two side plates 6 are fixedly connected to the upper surface of the bottom plate 1, and seven equally spaced protective plates 7 are fixedly connected to the upper surface of the bottom plate 1. The front and back sides of the protective plates 7 are fixedly connected with reinforcement plates 17. The bottom surface of each reinforcement plate 17 is fixedly connected to the upper surface of the bottom plate 1 to support and reinforce the protective plates 7 and increase the stability of the protective plates 7. A threaded rod 8 is rotatably inserted inside each protective plate 7. Seven driving gears 5 are fixedly sleeved on the outer circumferential surface of the output shaft 3. A driven gear 10 is fixedly connected to the bottom surface of the threaded rod 8. The driving gear 5 is meshed with the driven gear 10, so that the output shaft 3 drives the driven gear 10 to rotate through the driving gear 5 during the rotation process, thereby realizing the linkage between the output shaft 3 and the threaded rod 8.

[0024] The outer circumference of the threaded rod 8 is threadedly connected with a protective cone 11, and the outer circumference of the protective cone 11 is slidably plugged into the inside of the protective plate 7. Two ground nails 16 are fixedly connected to the bottom surface of the base plate 1. The motor 2 can be started as a power to drive the driving gear 5 to rotate through the output shaft 3, and then the threaded rod 8 is driven to rotate through the driven gear 10. The threaded rod 8 drives the protective cone 11 to rise and fall. The protective cone 11 can be adjusted as needed, which can facilitate the transportation of the fence and improve the safety of the fence.

[0025] See also Figure 2 , Figure 3 The outer circumference of the threaded rod 8 is fixedly sleeved with a limiting ring 9, and the outer circumference of the limiting ring 9 is rotatably connected to the inside of the protective plate 7 to limit the threaded rod 8, prevent the threaded rod 8 from sliding longitudinally, and increase the stability of the threaded rod 8 movement.

[0026] See also Figure 1 , Figure 2 , Figure 3 The left and right sides of the protective plate 7 are provided with limiting grooves 13, and the outer circumferential surface of the protective cone 11 is fixedly connected to two limiting blocks 12. The outer surface of each limiting block 12 is slidably connected to the protective plate 7 through the limiting groove 13, so as to limit the protective cone 11, prevent the protective cone 11 from rotating with the threaded rod 8, and prevent it from separating from the threaded rod 8 and falling off.

[0027] See also Figure 1 , Figure 2 , Figure 3 Eight connecting plates 14 are provided above the bottom plate 1, and an anti-stepping ring 15 is rotatably sleeved on the outer circumference of each connecting plate 14. The side of each connecting plate 14 close to the protective plate 7 is fixedly connected to the protective plate 7, and the sides of two connecting plates 14 close to the side plates 6 are fixedly connected to the side plates 6, so as to connect and reinforce the protective plate 7, increase the stability and safety of the fence, and prevent people from stepping on the fence and trying to climb over.

[0028] The implementation principle of a construction fence in an embodiment of the present application is as follows: the fence can be installed through ground nails 16, which is convenient for installation and disassembly of the fence and increases the stability of the fence. When the height of the fence needs to be raised to improve the safety of the fence, the starting motor 2 is used as power to drive the driving gear 5 to rotate through the output shaft 3, and the driving gear 5 drives the threaded rod 8 to rotate through the driven gear 10. The threaded rod 8 drives the protective cone 11 to be lifted under the restriction of the limit block 12 and the limit groove 13. Then the height of the protective cone 11 is raised to prevent the fence from being easily climbed over. When someone steps on the anti-stepping ring 15 and tries to climb over the fence, the anti-stepping ring 15 will be rotated on the connecting plate 14 due to the force, making it impossible for the climber to stand firmly on the anti-stepping ring 15, thereby improving the safety of the fence.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
