Description

Technical Field

[0001] This utility model relates to the field of construction fence technology, and in particular to an assembled construction fence. Background Technology

[0002] Construction fencing is one of the most common construction safety measures we see in our daily lives. Its main purpose is to isolate the construction site from the external environment, creating a relatively enclosed environment and ensuring the smooth progress of construction.

[0003] For example, patent application number CN202420393707.2 discloses a construction fence, including a left stake and a protective assembly. The protective assembly includes a right stake, two guide rods, two sliders, two railings, a winding roller, a shielding cloth, a locking mechanism, and two mounting plates. In normal use, both railings are perpendicular to the left stake, and the shielding cloth unfolds from the winding roller. The two railings, the shielding cloth, the left stake, and the right stake form the fence. This structure is easy to fold and store, avoiding the need for excessive transportation space. During assembly, the main body of this type of fence is fixed between two stakes, which are then fixed to the ground via bolts. However, because the stakes are only fixed to the ground at one connection point, when strong winds impact the fence, the force is transmitted to the stakes. This single-point connection is insufficient to effectively offset the impact, causing the stakes to tilt to one side, and in severe cases, the entire fence to collapse, losing its protective function. This needs further optimization. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an assembly-type construction fence to overcome the shortcomings of existing designs.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a modular construction fence, including a fence, with posts on the left and right sides of the fence, and the posts and the fence are detachably connected;

[0006] The fence is provided with diagonal bracing arms on the front and rear sides. The upper end of the diagonal bracing arms is hinged to the post through a connecting hinge seat. The mounting base A is provided below the diagonal bracing arms. A length adjustment mechanism is provided between the mounting base A and the diagonal bracing arms.

[0007] A positioning plate is provided on the side of the post away from the fence. The positioning plate is rotatably connected to the post via a pivot. The left and right ends of the positioning plate are provided with bolt positioning parts. The outside of the post is provided with a pin hole structure A that cooperates with the bolt positioning parts. The outside of the diagonal brace is provided with a pin hole structure B that cooperates with the bolt positioning parts.

[0008] A further improvement is that the length adjustment mechanism includes a movable arm, the lower end of which is hinged to the lower end of the mounting base A, the upper end of which is inserted into a slot opened at the lower end of the diagonal support arm, the movable arm is slidably connected to the slot, and the lower end of the diagonal support arm is provided with a positioning component for limiting the sliding of the movable arm.

[0009] A further improvement is that the positioning component includes a first positioning bolt, which is assembled at the lower end of the diagonal brace arm. The first positioning bolt is screwed into the slot and threadedly connected to a third positioning hole opened on the outside of the movable arm. The outside of the movable arm has multiple third positioning holes, and each third positioning hole is evenly arranged along the length of the movable arm.

[0010] A further improvement is that the bolt positioning component includes a second positioning bolt, which is assembled at both ends of the positioning plate and passes through the positioning plate and is threadedly connected to the positioning plate.

[0011] A further improvement is that the pin hole structure A includes two positioning holes A, which are opened on the side of the column away from the fence. The distance between the two positioning holes A is equal to the distance between the two second positioning bolts, and the positioning holes A are threadedly connected to the second positioning bolts.

[0012] A further improvement is that the pin hole structure B includes a positioning hole B opened on the outside of the diagonal brace arm. The positioning hole B is threadedly connected to the second positioning bolt. The outside of the diagonal brace arm has multiple positioning holes B, and each positioning hole B is evenly arranged along the length of the diagonal brace arm.

[0013] A further improvement is that: multiple second bolt ears are provided on the left and right sides of the fence, and the second bolt ears are fixedly connected to the fence; multiple first bolt ears are provided on the side of the post near the fence, and the first bolt ears are fixedly connected to the post; the first bolt ears and the second bolt ears are at the same height and staggered from each other; the first bolt ears are detachably connected to the second bolt ears by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the diagonal bracing arm is extended, it can support the posts from both the front and rear sides of the fence. Rotating the positioning plate will lock the diagonal bracing arm with the bolts at both ends of the positioning plate. The positioning plate, the posts, and the diagonal bracing arm form multiple stable triangular support structures, which effectively improves the structural strength and impact resistance of the construction fence.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a modular construction fence, including a fence 1, with posts 2 on the left and right sides of the fence 1, and the posts 2 are detachably connected to the fence 1; the split design makes it easy to carry and transport the fence 1 and the posts 2.

[0025] The fence 1 is provided with diagonal bracing arms 6 on the front and rear sides. The upper end of the diagonal bracing arm 6 is hinged to the post 2 through the connecting hinge seat 15. The diagonal bracing arm 6 is provided with a mounting base A7 below it. A length adjustment mechanism is provided between the mounting base A7 and the diagonal bracing arm 6.

[0026] The diagonal bracing arm 6 is set on the front and rear sides of the fence 1. The mounting base A7 is connected to the lower end of the diagonal bracing arm 6 through a length adjustment mechanism. By unfolding the diagonal bracing arm 6, the mounting base A7 extends from below the diagonal bracing arm 6 and is fixed to the bottom surface. The mounting base A7 will cooperate with the diagonal bracing arm 6 to support the post 2 from the front and rear sides of the fence 1, thereby improving the wind resistance of the construction fence.

[0027] A positioning plate 8 is provided on the side of the post 2 away from the fence 1. The positioning plate 8 is rotatably connected to the post 2 via a pivot. The left and right ends of the positioning plate 8 are provided with bolt positioning parts. The outer side of the post 2 is provided with a pin hole structure A that cooperates with the bolt positioning parts. The outer side of the diagonal brace 6 is provided with a pin hole structure B that cooperates with the bolt positioning parts.

[0028] After the diagonal brace 6 is unfolded and the mounting base A7 is fixed, rotate the positioning plate 8 and move the bolt positioning parts at both ends of the positioning plate 8 to one side of the two diagonal braces 6. The bolt positioning parts will cooperate with the pin hole structure B on the outside of the diagonal brace 6, thereby locking the diagonal brace 6. The positioning plate 8 will form multiple stable triangular support structures with the column 2 and the diagonal brace 6, further strengthening the structural strength and impact resistance of the diagonal brace 6 and the column 2.

[0029] Regarding the length adjustment mechanism:

[0030] The length adjustment mechanism includes a movable arm 10, the lower end of which is hinged to the lower end of the mounting base A7, the upper end of which is inserted into the slot 16 opened at the lower end of the diagonal support arm 6, and the movable arm 10 is slidably connected to the slot 16. The lower end of the diagonal support arm 6 is provided with a positioning component for limiting the sliding of the movable arm 10.

[0031] The movable arm 10 is assembled to the lower end of the diagonal brace arm 6 by plugging and unplugging. The positioning component is used to fix the movable arm 10 and the diagonal brace arm 6. After the positioning component is released from fixing the movable arm 10, the telescopic length of the movable arm 10 and the diagonal brace arm 6 can be adjusted to ensure that the mounting base A7 at the bottom of the movable arm 10 can contact the bottom surface, so that the movable arm 10 and the diagonal brace arm 6 can effectively support the column 2 from the front and rear sides.

[0032] Specifically, the positioning component includes a first positioning bolt 11, which is mounted on the lower end of the diagonal brace 6. The first positioning bolt 11 is screwed into the slot 16 and threadedly connected to the third positioning hole 17 opened on the outside of the movable arm 10. The movable arm 10 has multiple third positioning holes 17 on its outside, and each third positioning hole 17 is evenly arranged along the length of the movable arm 10.

[0033] Rotate the first positioning bolt 11 to unscrew it from the third positioning hole 17 on the outside of the movable arm 10, thereby releasing the fixation between the diagonal brace 6 and the movable arm 10. Adjust the extension and retraction length of the movable arm 10. After the length adjustment is completed, screw the first positioning bolt 11 on the outside of the diagonal brace 6 into one of the third positioning holes 17 on the outside of the movable arm 10 to lock the position of the movable arm 10 after extension and retraction.

[0034] Regarding the bolt positioning component:

[0035] The positioning element includes a second positioning bolt 13, which is assembled at both ends of the positioning plate 8 and passes through the positioning plate 8 and is threadedly connected to the positioning plate 8.

[0036] Specifically, the pin hole structure A includes two positioning holes A9, which are located on the side of the column 2 away from the fence 1. The distance between the two positioning holes A9 is equal to the distance between the two second positioning bolts 13, and the positioning holes A9 are threadedly connected to the second positioning bolts 13.

[0037] Rotate the positioning plate 8 so that it is attached to one side of the column 2 and kept parallel to the column 2. After the second positioning bolts 13 at both ends of the positioning plate 8 correspond to the two positioning holes A9 on the outside of the column 2, screw the second positioning bolts 13 into the corresponding positioning holes A9 to lock the positioning plate 8 and ensure that the positioning plate 8 will not fall apart when the column 2 is transported.

[0038] Specifically, the pin hole structure B includes a positioning hole B12 opened on the outside of the diagonal brace 6. The positioning hole B12 is threadedly connected to the second positioning bolt 13. The outside of the diagonal brace 6 has multiple positioning holes B12, and each positioning hole B12 is evenly arranged along the length of the diagonal brace 6.

[0039] With the diagonal bracing arm 6 in the extended state, rotate the positioning plate 8 so that the positioning plate 8 is perpendicular to the column 2. The second positioning bolts 13 at the left and right ends of the positioning plate 8 will correspond to a set of positioning holes B12 at the same height on the two diagonal bracing arms 6. Screw the second positioning bolts 13 into them to complete the locking between the positioning plate 8 and the diagonal bracing arm 6.

[0040] Similarly, the lower end of the column 2 is provided with a mounting base B14, which is fixedly connected to the column 2. Both the mounting base B14 and the mounting base A7 are equipped with connecting bolts, which, through the engagement of the connecting bolts with the connecting holes on the ground, firmly fix the movable arm 10 and the column 2 to the flat ground.

[0041] It is worth explaining in detail that multiple second bolt ears 4 are provided on the left and right sides of the fence 1. The second bolt ears 4 are fixedly connected to the fence 1. Multiple first bolt ears 3 are provided on the side of the post 2 near the fence 1. The first bolt ears 3 are fixedly connected to the post 2. The first bolt ears 3 and the second bolt ears 4 are at the same height and staggered from each other. The first bolt ears 3 are detachably connected to the second bolt ears 4 by bolts.

[0042] The first bolt lug 3 is fixedly installed on the outside of the post 2, and the second bolt lug 4 is fixedly installed on the left and right sides of the fence 1. When assembling, the fence 1 is placed between the two posts 2, and the second bolt lug 4 on the left and right sides of the fence 1 abuts against one side of the first bolt lug 3. The connecting bolt is screwed into the corresponding threaded holes on the first bolt lug 3 and the second bolt lug 4 to complete the fixing of the post 2 and the fence 1.

[0043] A warning panel 5 is installed on the fence 1, and the warning panel 5 is fixedly connected to the front and rear sides of the fence 1. The warning panel 5 is coated with a reflective coating, which can refract light under illumination and provide a warning to passing vehicles in dim environments.

[0044] How this application works:

[0045] The diagonal bracing arms 6 are installed on the front and rear sides of the fence 1. The mounting base A7 is connected to the lower end of the diagonal bracing arms 6 through a length adjustment mechanism. By unfolding the diagonal bracing arms 6, the mounting base A7 extends from below the diagonal bracing arms 6 and is fixed to the bottom surface. The mounting base A7, together with the diagonal bracing arms 6, supports the posts 2 from the front and rear sides of the fence 1, improving the wind resistance of the construction fence. After the diagonal bracing arms 6 are unfolded and the mounting base A7 is fixed, the positioning plate 8 is rotated, and the bolt positioning parts at both ends of the positioning plate 8 are moved to one side of the two diagonal bracing arms 6. The bolt positioning parts will cooperate with the pin hole structure B on the outside of the diagonal bracing arms 6, thereby locking the diagonal bracing arms 6. The positioning plate 8, together with the posts 2 and the diagonal bracing arms 6, will form multiple stable triangular support structures, further strengthening the structural strength and impact resistance of the diagonal bracing arms 6 and the posts 2.
