Description

Technical Field

[0001] This invention relates to the field of construction guardrails, and more particularly to a flexible adjustable construction boundary guardrail. Background Technology

[0002] With the continuous advancement of engineering management and the inevitable demands of social development, construction projects are increasingly requiring safe and civilized construction practices. Standardized guardrails need to be rationally installed. In building construction, municipal renovation, road maintenance, and temporary site isolation operations, guardrail structures are typically required at construction boundaries to regulate construction areas, ensure on-site safety, isolate pedestrians and vehicles, and reduce construction interference. These guardrails serve for necessary safety protection, material containment, construction road clearance, and site demarcation.

[0003] Existing construction guardrails typically consist of a fence frame and posts. The fence frame is extended by the posts to protect the boundary of the construction site. However, this design has significant shortcomings in practical use. Because the angle between the posts is fixed, conventional guardrails cannot be flexibly adjusted according to the terrain, road width, turning areas, and slope locations. This results in poor adaptability. When encountering curved boundaries, corners, slopes, or road sections with varying widths, ordinary guardrails are difficult to fit snugly against the boundary, easily leading to gaps, tilting, or incomplete overlaps.

[0004] Therefore, a flexible construction boundary fence has now been developed that can adjust the angle between the posts to adapt to complex site boundaries. Summary of the Invention

[0005] To overcome the shortcomings of existing construction guardrails, which have fixed angles between posts and are not suitable for complex construction site boundaries, this invention provides a flexible construction boundary guardrail that allows for adjustment of the angles between posts to adapt to complex site boundaries.

[0006] The technical solution is as follows: A flexibly adjustable construction boundary guardrail includes a base, wheels, posts, slide rails, sliders, cylinders, switches, spray components, telescopic railings, and splicing components. There are four posts. The leftmost and rightmost posts are rotatably connected to wheels on their lower sides. The second and third posts from left to right are connected to bases on their lower sides. Each post has a slide rail inside, and sliders are slidably connected to the slide rails. Each post has a cylinder inside, and the telescopic ends of the cylinders are connected to adjacent sliders. Switches are located on the front and rear sides of the lower part of the second and third posts from left to right. Each post has a spray component, and the cylinders and switches are connected by wires. A telescopic railing is rotatably connected between the first and second posts from left to right, and also rotatably connected between the third and fourth posts from left to right. Sliders are rotatably connected to adjacent telescopic railings. A splicing component is located between the second and third posts from left to right.

[0007] As a further preferred option, the wheels are equipped with anti-slip mats.

[0008] As a further preferred option, a cover is also included, with cover connected to the front and rear sides of the lower part of the second and third columns from the left, and the cover is located outside the adjacent switches.

[0009] As a further preferred embodiment, the spray assembly includes a rotating shaft and a sprayer, with the upper part of the column being connected to the rotating shaft via a damped rotating mechanism, and the rotating shaft being connected to the sprayer.

[0010] As a further preferred option, the splicing assembly includes a fixing frame and a pin. The second and third columns from the left are each connected to two fixing frames on their upper and lower sides that are close to each other, and the fixing frames are engaged with pins.

[0011] As a further preferred option, a handle is provided on the upper part of the pin.

[0012] The present invention has the following advantages: 1. The present invention adjusts the angle between the two central columns by rotating them, thereby rotating the fixed frame relative to the pin. The wheels move the leftmost and rightmost columns, thus achieving the ability to adjust the angle between the columns to adapt to complex site boundaries.

[0013] 2. This invention adjusts the angle of the rotating shaft by rotating it, and then sprays water mist from the sprayer to reduce dust in the construction area, thus protecting the surrounding environment. Attached Figure Description

[0020] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0021] A flexible, adjustable construction boundary fence, such as Figures 1-5 As shown, the system includes a base 1, wheels 2, columns 3, slide rails 30, sliders 31, cylinders 32, switches 4, a cover 5, a spray assembly, a telescopic railing 8, and a splicing assembly. There are four columns 3. The leftmost and rightmost columns 3 are rotatably connected to wheels 2 on their undersides. The wheels 2 have anti-slip pads to increase grip. The second and third columns 3 from left to right are connected to the base 1 on their undersides. Each column 3 has a slide rail 30 connected inside, and each slide rail 30 has a slider 31 slidably connected to it. Each column 3 has a cylinder 32 connected inside, and the telescopic ends of the cylinders 32 are connected to the adjacent sliders 31. From left to right... Switches 4 are provided on the front and rear sides of the lower part of the second and third columns 3 from the right. Spraying components are provided on the columns 3. Covers 5 are connected to the front and rear sides of the lower part of the second and third columns 3 from the left. The cover 5 is located outside the adjacent switch 4. The cylinder 32 is connected to the switch 4 by wires. Telescopic railings 8 are rotatably connected between the first and second columns 3 from the left. Telescopic railings 8 are also rotatably connected between the third and fourth columns 3 from the left. Slider 31 is rotatably connected to the adjacent telescopic railings 8. A splicing component is provided between the second and third columns 3 from the left.

[0022] like Figure 1 and Figure 3 As shown, the spray assembly includes a rotating shaft 6 and a sprayer 7. The upper part of the column 3 is connected to the rotating shaft 6 by a damped rotating mechanism, and the sprayer 7 is connected to the rotating shaft 6.

[0023] like Figures 1-4 As shown, the splicing assembly includes a fixed frame 9 and a pin 10. From left to right, the second and third columns 3 are connected to two fixed frames 9 on their upper and lower sides that are close to each other. The fixed frames 9 are engaged with the pins 10. The pins 10 have a handle on the upper part for easy disassembly.

[0024] When using this invention, first place the base 1 at the boundary of the construction site. Connect the two central columns 3 by using the fixed frame 9 and the pin 10. Then, according to the boundary of the construction site, press the switch 4 to start the cylinder 32. The telescopic end of the cylinder 32 pushes the slider 31 to move on the slide rail 30, causing the telescopic railing 8 to extend. The wheels 2 move the leftmost and rightmost columns 3 to adapt to the length of the construction site boundary. The cover 5 covers and protects the switch 4. When the boundary of the construction site is at an angle, rotate to adjust the angle between the two central columns 3, causing the fixed frame 9 to rotate relative to the pin 10. The wheels 2 move the leftmost and rightmost columns 3 to adapt to different angles of the construction site boundary. During construction, the angle of the rotating shaft 6 can be adjusted by rotating, and the sprayer 7 can spray water mist to reduce dust in the construction area and maintain the surrounding environment.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
