Description

Technical Field

[0001] This utility model relates to the field of warning fence technology, specifically a warning fence for construction projects. Background Technology

[0002] Construction site warning fences are protective facilities installed around construction sites or in specific hazardous areas. They serve functions such as isolation and protection, safety warnings, and clearly defining the scope and boundaries of the construction area. Excavation pit warning fences are a type of construction site warning fence specifically designed for the protection of the area around excavation pits. Existing excavation pit warning fences mainly consist of two posts with a surrounding panel between them. Fixing lugs with mounting holes are installed at corresponding positions on both the posts and the surrounding panel. During installation, the two posts are first fixed to their bases using embedded parts. Then, the position of the surrounding panel needs to be continuously adjusted. The mounting holes on the fixing ears of the posts and the perimeter panels are aligned and screwed in. While one person is screwing in the screws, the other person needs to hold the other side of the perimeter panel to keep it vertical and parallel. After fixing one fixing ear, the screws are then screwed in on the fixing ears on the other side of the posts and the perimeter panel. This requires two people to work together, which increases manpower input, makes the operation cumbersome, and is time-consuming and labor-intensive. In addition, different heights of fences are required for different depths of foundation pits to meet the existing warning fences in the safety technical specifications. However, the height of the existing foundation pit warning fences is fixed and cannot be adjusted, resulting in poor applicability. Utility Model Content

[0034] The present invention will be further explained below with reference to specific embodiments.

[0035] Please see Figures 1-12 This embodiment provides a warning fence for construction projects, including two posts 1. A horizontal support plate 13 is installed at the bottom of each post 1. A third mounting hole 14 is provided at the corner of the support plate 13. The posts 1 are fixed by drilling holes in the ground or installing pre-embedded parts, and bolts are passed through the third mounting holes 14. A first fence 2 is installed between the two posts 1. Fixing blocks 11 are provided at the upper and lower parts of the inner sidewall of each post 1. Each fixing block 11 has an opening-shaped snap-fit ​​groove 12. 12. The inner snap-fit ​​connector 21 is set on the side wall of the first fence 2; the top surface of the first fence 2 is hinged to the second fence 3. The first fence 2 and the second fence 3 are painted with red and white or black and yellow warning paint and a safety warning sign (not shown in the figure) is hung in the middle; the side walls of the first fence 2 and the second fence 3 on the same side are respectively provided with the insertion pipe 22 and the adjustment hole 31. The insertion pipe 22 and the adjustment hole 31 are connected by the snap-fit ​​connector 4. The snap-fit ​​connector 4 is used to fix the first fence 2 and the second fence 3. The warning fence uses a snap-fit ​​connector 21 on the first fence 2, which snaps into the snap-fit ​​groove 12 of the fixing block 11 on the side wall of the post. This allows the first fence 2 to be more easily initially fixed to the post 1 without the need for continuous lifting of the fence panel, greatly reducing the difficulty and complexity of the installation operation, reducing manpower input, and improving installation efficiency. Furthermore, through the hinge between the first fence 2 and the second fence 3, as well as the cooperation between the plug pipe 22 and the adjustment hole and the plug connector 4, the fence height can be flexibly adjusted. The appropriate fence height can be selected according to the depth of different foundation pits, meeting the requirements of safety technical specifications and improving the applicability of the fence.

[0036] like Figures 6-8As shown, in this embodiment, the snap-fit ​​groove 12 includes an inverted trapezoidal groove 121 disposed on the top surface of the fixing block 11, and a U-shaped groove 122 connected to the lower part of the inverted trapezoidal groove 121.

The trapezoidal channel 123 penetrates the bottom and top surfaces of the fixing block 11. The side of the trapezoidal channel 123 is connected to the trapezoidal channel 123 and the U-shaped groove 122. The snap-fit ​​groove 12 adopts an inverted trapezoidal structure with a wide upper opening and a narrow lower U-shaped groove. The inclined surface guides the cylinder of the snap-fit ​​component to slide into the groove, reducing the requirement for precise alignment during installation. The U-shaped groove provides the final fixing position for the snap-fit ​​component 21, and at the same time aligns the first mounting hole 214 and the second mounting hole 124, which facilitates bolt fixing, reduces the difficulty and complexity of the installation operation, and improves the installation efficiency.

[0037] like Figure 3 , Figure 9 , Figure 11 As shown, in this embodiment, the first fence 2 includes a first frame 25. A kick plate 23 is provided at the bottom of the first frame 25. The kick plate 23 is located at the bottom of the warning fence, close to the ground, which can effectively prevent people, especially children and pets, from crawling into the pit area from the bottom of the fence, preventing accidental falls and further enhancing the safety protection performance around the pit. The kick plate 23 uses the same warning paint as the first fence 2 and the second fence 3 (not shown in the figure), which echoes the overall warning color of the fence, creating a stronger visual enclosure and warning effect around the pit. Multiple vertical dividing square tubes are also evenly arranged inside the first frame 25. The upper and lower parts of the two side walls of the first frame 25 are provided with snap-fit ​​parts 21, and the upper part of the snap-fit ​​parts 21 on the two side walls of the first frame 25 is provided with insertion pipes 22. The snap-fit ​​component 21 includes a vertical mounting plate 211. A horizontal cylinder 212 is provided on the side of the mounting plate 211 opposite to the fixing block 11. A trapezoidal block 213 is provided on the top surface of the cylinder 212. The trapezoidal block 213 is adapted to the trapezoidal channel 123, and the cylinder 212 is adapted to the U-shaped groove 122. A first mounting hole 214 is provided on one side of the cylinder 212 on the mounting plate 211. The first mounting hole 214 and the second mounting hole 124 are provided correspondingly. The second mounting hole 124 is provided on the fixing block 11, located on one side of the snap-fit ​​groove 12. The second mounting hole 124 is a round hole, and the first mounting hole 214 is an oblong hole.

[0038] like Figure 2 , Figure 3 , Figure 11 , Figure 12 As shown, in this embodiment, the second fence 3 includes a second frame 32. The lower part of both sides of the second frame 32 body is provided with through adjustment holes 31. The adjustment holes 31 are oblong holes. Multiple vertical dividing square tubes are provided inside the second frame 32. The bottom surface of the second frame 32 is connected to the top surface of the first frame 25 by a hinge 5.

[0039] like Figures 10-12 As shown, in this embodiment, the connector 4 includes a first column 41 and a second column 42, which are connected in an L-shape. The first column 41 passes through the adjustment hole 31 and is screwed with a bolt 411 at its end. When the second fence 3 is vertically erected on top of the first fence 2, the end of the second column 42 is inserted into the connector tube 22. The connector 4 also includes a third column 43, which is located in the middle of the first column 41. The third column 43 is perpendicular to both the first column 41 and the second column 42. When the second fence 3 is in a folded state, the end of the third column 43 is inserted into the connector tube 22. This design, through the hinged connection between the first and second fences and the cooperation of the insertion pipes, adjustment holes, and connectors, enables flexible adjustment of the fence height. The appropriate fence height can be selected according to the depth of different foundation pits, meeting safety technical specifications and improving the fence's applicability. The hinged design between the second and first fences, and the detachable connectors, allow the fence to be easily folded when not in use. The folded fence occupies little space, is easy to store, and saves storage space on the construction site.

[0040] This utility model provides a working principle for a warning fence used in construction engineering: In use, firstly, the upright post 1 is fixed by drilling holes in the ground or installing pre-embedded parts, and then bolts are passed through the third mounting hole 14 to secure the upright post 1. Then, only one worker needs to move the first fence 2 to a vertical position, and the lower part of the mounting plate 211 in the snap-fit ​​parts 21 on both sides of the first fence 2 abuts against the opposite side wall of the trapezoidal channel 123 in the fixing block 11. At this time, the cylinder 212 is located above the inverted trapezoidal groove 121, and the two side walls of the trapezoidal channel 123 are misaligned and abutting against the two side walls of the trapezoidal block 213. The worker can then release the first fence 2, and the cylinder 212 either falls directly into the U-shaped groove 122 or slides into the U-shaped groove 122 guided by the inclined surface of the inverted trapezoidal groove 121. The trapezoidal block 213 and the trapezoidal... With the side walls of passage 123 completely abutting, the first fence 2 can be more easily initially fixed to the post 1 without continuous support. At this time, the first mounting hole 214 and the second mounting hole 124 are aligned, facilitating bolt fixing, greatly reducing the difficulty and complexity of installation, improving installation efficiency, and reducing manpower input. When the height of the first fence 2 does not meet the requirements, loosen the bolt 411, pull the third post 43 out of the insertion pipe 22, flip the second fence 3 hinged on the first fence 2 into a vertical state, with the bottom surface of the second fence 3 abutting the top surface of the first fence 2, and insert the second post 42 into the insertion pipe 22. Tighten the bolt 411 to fix the second fence 3 to the top of the first fence 1, thereby increasing the overall height of the warning fence and improving its applicability. The hinged connection between the first fence 1 and the second fence 2, and the cooperation between the plug pipe 22 and the adjustment hole 31 and the plug fitting 22, enable flexible adjustment of the fence height. The appropriate fence height can be selected according to the depth of different foundation pits, meeting the requirements of safety technical specifications and improving the applicability of the fence. The hinged design between the second fence 3 and the first fence 2, as well as the detachable plug fitting, allows the fence to be easily folded when not in use. The folded fence occupies little space, is easy to store, and saves storage space on the construction site.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
