Description

Technical Field

[0001] This utility model relates to the field of construction site enclosure technology, and in particular to a quick-installation maintenance enclosure for road construction. Background Technology

[0002] With the continuous development and construction of cities, road construction projects such as new construction, reconstruction, and routine maintenance are frequently carried out. To ensure construction safety, maintain traffic order, and protect pedestrians and vehicles from potential hazards in the construction area, setting up barriers around the construction zone has become an essential measure. Barriers effectively isolate the construction area from normal traffic areas, preventing unauthorized personnel and vehicles from entering the construction site and avoiding safety accidents. They also reduce the disturbance to the surrounding environment caused by construction dust and noise.

[0003] Currently, common road construction maintenance fencing on the market mainly consists of two parts: posts and fences. The posts, as supporting structures, are typically fixed vertically to the ground, providing stable support for the fence; the fence serves as the actual isolation barrier. During installation, the fence is generally fixed to the posts using multiple bolt assemblies. Specifically, multiple bolt holes need to be pre-drilled at corresponding positions on both the fence and the posts. The bolts are then passed through these holes sequentially and tightened with nuts on the other side, thus achieving a secure connection between the fence and the posts. However, the existing fencing requires multiple bolt assemblies, making assembly cumbersome. Installing each bolt individually requires aligning the holes, inserting the bolt, and tightening the nuts, increasing workload and installation time. While tightening the bolts, the fence must be held steady to prevent swaying and displacement, which is extremely inconvenient and further reduces installation efficiency. Utility Model Content

[0004] In view of this, this utility model proposes a quick-installation maintenance fence for road construction, aiming to improve the installation efficiency and ease of operation of the fence to at least a certain extent.

[0005] The solution provided by this utility model includes:

[0006] A quick-installation road construction maintenance barrier includes:

[0007] Multiple columns, each column comprising a column body and a base fixed to the bottom of the column body. The column body is an I-beam, comprising a web and a first flange plate and a second flange plate disposed on both sides of the web plate. A positioning post extending horizontally is provided on the inner side of the first flange plate, and one end of the positioning post is at a certain distance from the second flange plate. There are four positioning posts on the column, and the four positioning posts are distributed in a longitudinal and transverse matrix.

[0008] Several fences, each fence including a main frame and a mesh panel fixed to a first side of the main frame, the fence being set between two adjacent posts, and the second side of the fence being connected to the positioning posts; wherein, two positioning posts on each of the two posts correspond to the four corner positions inside the fence, so as to fix the fence in the longitudinal and transverse directions.

[0009] An upper fixing member is provided on the upper part of the post and located between the second flange plate and the first side of the fence;

[0010] The lower fixing member is disposed at the lower part of the post and located between the second flange plate and the first side of the fence;

[0011] The upper fixing member and the lower fixing member are respectively connected to the column bolts.

[0012] As a further optional solution, the upper part of the column is provided with two upper fixing members, which are respectively located on both sides of the web plate; the upper part of the web plate is provided with a first through hole, and the upper fixing member is provided with a second through hole corresponding to the axial direction of the first through hole; a bolt assembly is provided between the first through hole and the second through hole to realize the fixation between the column and the upper fixing member.

[0013] As a further alternative, two upper fixing parts corresponding to a column are welded and fixed to the bottom of a top cover, which is located on the top of the column.

[0014] As a further optional solution, the lower part of the column is provided with two lower fixing members, which are located on both sides of the web plate respectively; the lower part of the web plate is provided with a third through hole, and the lower fixing member is provided with a fourth through hole corresponding to the axial direction of the third through hole; a bolt assembly is provided between the third through hole and the fourth through hole to realize the fixation between the column and the lower fixing member.

[0015] As a further optional feature, the fence may also include a reinforcing frame disposed within the main frame.

[0016] As a further alternative, the main frame is formed by welding C-shaped steel or square steel.

[0017] As a further optional solution, the base is a steel plate, and the base is provided with mounting holes.

[0018] Compared with the prior art, this application has at least the following advantages:

[0019] This application achieves rapid pre-positioning of the fence by using positioning posts on the uprights and cooperating with the four corners of the fence. During installation, simply hanging the fence against the positioning posts completes the longitudinal and lateral fixation of the fence, eliminating the need for manual support to prevent swaying, a crucial step in traditional installation. This not only reduces the number of operators required but also allows for subsequent tightening operations to be carried out smoothly, greatly improving the installation experience and efficiency.

[0020] Furthermore, unlike traditional solutions that require multiple bolts to be drilled and tightened across the entire contact surface between the fence and the posts, this application eliminates the direct bolt connection between the fence and the posts, requiring only final tightening at two points: an upper fixing member and a lower fixing member. This significantly reduces the number of bolt assemblies used, decreases the number of bolt tightening operations, effectively shortens installation time, and improves overall construction efficiency.

[0036] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0037] refer to Figure 1-5 An embodiment of this utility model shows a quick-installation road construction maintenance fence, including multiple posts 1, several fences 2, upper fixing parts 3 and lower fixing parts 4.

[0038] The column 1 includes a column body 11 and a base 12 fixed to the bottom of the column body 11. The column body 11 is an I-beam, which includes a web 111 and a first flange 112 and a second flange 113 disposed on both sides of the web 111. The inner side of the first flange 112 is provided with a positioning post 114 extending in the horizontal direction. One end of the positioning post 114 is at a certain distance from the second flange 113. There are four positioning posts 114 on the column 1, and the four positioning posts 114 are distributed in a longitudinal and transverse matrix.

[0039] The fence 2 includes a main frame 21 and a mesh panel 22 fixed to the first side of the main frame 21. The fence 2 is set between two adjacent posts 1, and the second side of the fence 2 is connected to the positioning post 114. The two positioning posts 114 on each of the two posts 1 correspond to the four corner positions inside the fence 2, so as to fix the fence 2 in the longitudinal and transverse directions.

[0040] The upper fixing member 3 is disposed on the upper part of the column 1 and is located between the second flange plate 113 and the first side of the fence 2;

[0041] The lower fixing member 4 is provided at the lower part of the column 1 and is located between the second flange plate 113 and the first side of the fence 2;

[0042] The upper fixing member 3 and the lower fixing member 4 are respectively bolted to the column 1.

[0043] Specifically, in this embodiment, four positioning posts 114 are provided on the first flange plate 112 of the column 11, such as... Figure 2 As shown, the two positioning posts 114 located at the top are symmetrically arranged on both sides of the web 111; similarly, the two positioning posts 114 located at the bottom are also symmetrically arranged on both sides of the web 111.

[0044] Since the mesh panel 22 is located on the first side of the main frame 21, and the second side of the main frame 21 allows the positioning post 114 to be inserted, during installation, the side of the fence 2 can be inserted into the space between the second flange plate 113 and the positioning post 114, at which point the second side of the fence 2 faces the first flange plate 112, and then the fence 2 is pushed in the direction of the positioning post 114, as shown. Figure 3 as well as Figure 5 As shown, the upper and lower positioning posts 114 can be respectively engaged at the two corners of one side of the main frame 21, thereby achieving vertical positioning. Similarly, the other side of the fence 2 is connected to the positioning post 114 on another post 1, and the positioning posts 114 on the two posts 1 achieve horizontal positioning of the fence 2. Thus, in this embodiment, the positioning posts 114 on the posts 1 can achieve pre-positioning of the fence 2, and in subsequent fastening operations, it is not necessary to hold the fence 2 continuously.

[0045] Then, the upper fixing member 3 and the lower fixing member 4 can be fixed to the upper and lower parts of the column 1 respectively by bolt assembly 5; specifically, the upper fixing member 3 and the lower fixing member 4 can be metal blocks; such as Figure 3 and Figure 4As shown, taking the upper fixing member 3 as an example, after the upper fixing member 3 is fixed to the column 1, one side of the upper fixing member 3 abuts against the second flange plate 113, and the other side abuts against the first side of the fence 2, thus making the fence 2 inseparable from the positioning post 114; the function of the lower fixing member 4 is the same. Thus, compared with the prior art, this embodiment eliminates the need to open and tighten multiple bolts on the entire contact surface of the fence 2 and the column 1. This embodiment eliminates the direct bolt connection between the fence 2 and the column 1, requiring only final locking at two points: the upper fixing member 3 and the lower fixing member 4. This significantly reduces the number of bolt assemblies 5 used, reduces the number of bolt tightening operations, effectively shortens the installation time, and improves overall construction efficiency.

[0046] In some embodiments, such as Figure 2 and Figure 3 As shown, the upper part of the column 1 is provided with two upper fixing parts 3, which are located on both sides of the web 111 respectively; the upper part of the web 111 is provided with a first through hole 115, and the upper fixing part 3 is provided with a second through hole (not shown) that corresponds axially to the first through hole 115; a bolt assembly 5 is provided between the first through hole 115 and the second through hole to fix the column 1 and the upper fixing part 3.

[0047] Preferably, such as Figure 2 and Figure 3 As shown, two upper fixing parts 3 corresponding to a column 1 are welded and fixed to the bottom of a top cover 6, which is located on the top of the column 1.

[0048] In this embodiment, there is a gap between the two upper fixing members 3 located at the bottom of the top cover 6 for the web plate 111 to be inserted; by using the top cover 6 to make the two upper fixing members 3 into an integral structure, after the pre-positioning of the fence 2 and the positioning post 114 is completed, it is only necessary to put the top cover 6 upside down on the top of the post 1, without having to hold the upper fixing members 3 by hand, which facilitates the bolt tightening operation between the upper fixing members 3 and the post 1.

[0049] In some embodiments, such as Figure 5 As shown, the lower part of the column 1 is provided with two lower fixing parts 4, which are located on both sides of the web plate 111 respectively; the lower part of the web plate 111 is provided with a third through hole, and the lower fixing parts 4 are provided with a fourth through hole corresponding to the axial direction of the third through hole; a bolt assembly 5 is provided between the third through hole and the fourth through hole to realize the fixation between the column 1 and the lower fixing parts 4.

[0050] In this embodiment, the connection structure between the lower fixing member 4 and the column 1 can be referred to Figure 4 The connection structure between the upper fixing part 3 and the column 1.

[0051] In some embodiments, such as Figure 1 and Figure 2 As shown, to improve the strength of the fence 2, the fence 2 also includes a reinforcing frame 23 disposed within the main frame 21. In this embodiment, the reinforcing frame 23 is X-shaped.

[0052] In some embodiments, such as Figure 4 As shown, the main frame 21 is formed by welding C-shaped steel. In other embodiments, it may also be formed by welding square steel.

[0053] In some embodiments, such as Figure 4 or Figure 5 As shown, the base 12 is a steel plate, and the base 12 is provided with mounting holes 121. Expansion bolts can be driven into the mounting holes 121 to fix the base 12 to the ground. Alternatively, the mounting holes 121 can be connected to pre-embedded parts in the ground to fix the base 12.

[0054] In summary, this application provides a quick-installation maintenance fence for road construction. Through the cooperation of positioning posts 114 on the uprights 1 with the four corners of the fence 2, the fence 2 can be quickly pre-positioned. During installation, the fence 2 is simply hung against the positioning posts 114 to complete its longitudinal and lateral fixation, eliminating the need for manual support to prevent swaying in traditional installations. This not only reduces the number of operators required but also allows for subsequent tightening operations, greatly improving the installation experience and efficiency.

[0055] Furthermore, unlike traditional solutions that require multiple bolts to be installed and tightened across the entire contact surface between the fence 2 and the post 1, this application eliminates the direct bolt connection between the fence 2 and the post 1. Final tightening is achieved only at two points: the upper fixing member 3 and the lower fixing member 4. This significantly reduces the number of bolt assemblies 5 used, decreases the number of bolt tightening operations, effectively shortens installation time, and improves overall construction efficiency.

[0056] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
