Description

Technical Field

[0001] This utility model relates to the field of highway maintenance equipment technology, specifically to a quick-installation highway guardrail. Background Technology

[0002] like Figures 1 to 3 As shown, the highway guardrails currently used by municipal authorities mainly consist of posts 1, guardrail panels 2, and crossbeam connectors 9 for connecting the posts and guardrail panels; the structure of the crossbeam connectors 9 is as follows: Figure 3 As shown, the crossbeam connector 9 is a separately manufactured, independent part, usually fixed to the post 1 with four fasteners. Installation is relatively troublesome, and its sharp ends can easily injure people. Secondly, since the standard guardrail length is usually 3 meters, when connecting the end of the guardrail panel to the crossbeam connector, the distance between the two posts is relatively large. Combined with manufacturing errors and installation errors of the crossbeam connector, it is easy for the guardrail panel at the other end to misalign with the crossbeam connector, making installation difficult. Furthermore, a 3-meter-long guardrail is quite long and heavy, usually requiring at least two workers to complete the installation, and sometimes even requiring the use of cranes or other equipment. Thirdly, the standard 3-meter length guardrail panel is inflexible at curves and road ends; when the length is less than 3 meters, the guardrail panel needs to be custom-made. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-installation highway guardrail that eliminates the need for crossbeam connectors and fasteners between the posts and guardrail panels. It adopts an insert-type installation method, making installation more convenient and faster. At the same time, the guardrail panels can be spliced ​​together, and the length adjustment is more flexible.

[0004] This utility model includes a post, with at least one guardrail panel installed between two adjacent posts. The guardrail panel has mounting plates on its left and right sides, and mounting strips extending vertically on the mounting plates. On the side of the post, a fixing plate is provided at the corresponding position of the mounting plate. The fixing plate has a mounting groove extending vertically, and the size of the mounting groove is adapted to the mounting strip, so that the mounting strip can slide into and connect to the mounting groove.

[0005] With the above structure, during installation, first fix the posts on the left and right sides at the standard distance, lift the guardrail panel, align the bottom of the mounting strips on the left and right sides of the guardrail panel with the corresponding mounting grooves on the posts, and push the guardrail panel downwards so that it slides down along the mounting grooves until the bottom of the mounting strips rests against the limiting plate, thus completing the installation. Compared with the traditional connection method using crossbeam connectors, this structure eliminates the installation process of crossbeam connectors. At the same time, it avoids the installation difficulties caused by the long length of the guardrail panel and manufacturing errors, which make it difficult to align the ends of the guardrail panel with the crossbeam connectors.

[0006] Preferably, each mounting plate has at least two mounting strips, which are spaced apart and arranged side by side on the side of the guardrail panel; each fixing plate has at least two mounting slots, and the positions of the mounting slots correspond one-to-one with the positions of the mounting strips.

[0007] Preferably, a limiting plate is fixed at the bottom of the mounting groove.

[0008] Preferably, the guardrail panel has mounting plates on both the left and right sides, one of the mounting plates has a mounting strip extending vertically, and the other mounting plate has a mounting groove extending vertically, the size of which is adapted to the mounting strip; the mounting strip of one guardrail panel can slide into the mounting groove connected to the other guardrail panel.

[0009] Preferably, the mounting plate has through holes that extend horizontally through both the left and right ends of the mounting plate, and fasteners are inserted into the through holes.

[0010] Preferably, the length of the guardrail panels is provided in several different sizes.

[0011] Preferably, the post is provided with a fixing plate on both the left and right sides. One fixing plate has a mounting groove extending vertically, which allows the mounting strip on the guardrail to slide into and connect thereto. The fixing plate on the other side has a mounting strip extending vertically, which can slide into and connect to the mounting groove on the guardrail.

[0012] Preferably, several guardrail panels are installed between two adjacent posts.

[0013] In summary, this utility model has the following beneficial effects: 1. It adopts an integrated structure and plug-in installation, which is convenient and quick to install. There is no need to make a separate crossbeam connector or use separate fasteners. The structure is simple, the number of parts is small, and it saves costs and manpower. 2. Using fixed plates and mounting plates instead of crossbeam connectors avoids exposing the sharp ends of the crossbeam connectors, making it safer to use; 3. Fixed plates and mounting plates are used instead of crossbeam connectors, and an insert-type installation method is adopted, making it easier to align both ends with the column during installation; 4. The guardrail panels are designed to be short in length, making them lighter and easier to transport and install by a single person. In addition, the guardrail panels can be spliced ​​together to a suitable length as needed. The small size of the guardrail panels is more suitable for road ends and bends, eliminating the need for customization. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] The orientations mentioned in this specification are based on the orientation of the quick-installation highway guardrail of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0018] Example 1: like Figures 4 to 6 As shown, a quick-installation highway guardrail includes posts 1, with at least one guardrail panel 2 installed between two adjacent posts 1. Mounting plates 3 are provided on the left and right sides of the guardrail panel 2, and mounting strips 4 extending vertically are provided on the mounting plates 3. A fixing plate 5 is provided on the side of the post 1 at the corresponding position of the mounting plate 3, and a mounting groove 6 extending vertically is provided on the fixing plate 5. The mounting groove 6 is adapted to the size of the mounting strip 4, allowing the mounting strip 4 to slide into and connect to the mounting groove 6. This eliminates the need for the crossbeam connector 9 and fasteners between the post 1 and the guardrail panel 2, and adopts an insert-type installation method, making installation more convenient and faster.

[0019] Furthermore, each mounting plate 3 has at least two mounting strips 4, which are spaced apart and arranged side by side on the side of the guardrail piece 2; each fixing plate 5 has at least two mounting slots 6, and the positions of the mounting slots 6 correspond one-to-one with the positions of the mounting strips 4. The two mounting strips 4 correspond to the two mounting slots 6, which makes the guiding performance and stability of the mounting strips 4 and mounting slots 6 better when installing the guardrail piece 2, and less prone to skewing or deformation due to manufacturing errors.

[0020] Furthermore, the width of the upper and lower ends of the mounting plate 3 gradually decreases, which serves as a guide when the mounting strip 4 is slidably inserted into the mounting groove 6, making installation more convenient and easier.

[0021] Furthermore, a limiting plate 7 is fixed at the bottom of the mounting groove 6. When the mounting strip 4 is installed in place, the limiting plate 7 restricts the movement of the guardrail piece 2, preventing it from sliding downwards.

[0022] During installation, first fix the posts 1 on both sides at the standard distance, lift the guardrail panel 2, align the bottom of the mounting strips 4 on both sides of the guardrail panel 2 with the corresponding mounting grooves 6 on the posts 1, push the guardrail panel 2 downwards so that it slides down along the mounting grooves 6 until the bottom of the mounting strips 4 rests against the limiting plate 7, and the installation is completed. Compared with the traditional connection method using the crossbeam connector 9, this structure eliminates the installation process of the crossbeam connector 9. At the same time, it avoids the installation difficulties caused by the long length of the guardrail panel 2 and the difficulty in aligning the end of the guardrail panel 2 with the crossbeam connector 9 due to manufacturing errors.

[0023] Example 2: The difference between this embodiment and Embodiment 1 is that, Figures 7 to 10 As shown, mounting plates 3 are provided on the left and right sides of the guardrail 2. One mounting plate 3 has a mounting strip 4 extending vertically on one side, and a mounting groove 6 extending vertically on the other mounting plate 3. The mounting groove 6 is adapted to the size of the mounting strip 4. The mounting strip 4 of one guardrail 2 can slide into the mounting groove 6 connected to the other guardrail 2.

[0024] Furthermore, the mounting plate 3 is provided with through holes 8 that extend horizontally through both the left and right ends of the mounting plate 3, and fasteners are inserted into the through holes 8; since there is no limiting plate 7 at the bottom of the mounting plate 3, after the guardrail pieces 2 are spliced ​​together, in order to limit the guardrail pieces 2 and keep all the guardrail pieces 2 on the same horizontal line, the through holes 8 on two adjacent guardrail pieces 2 should be aligned, and fasteners should be inserted into the through holes 8 for fixation.

[0025] Furthermore, the left and right sides of the post 1 are provided with fixing plates 5. One fixing plate 5 is provided with a mounting groove 6 extending in the vertical direction, which allows the mounting strip 4 on the guardrail piece 2 to slide into and connect thereto. The other fixing plate 5 is provided with a mounting strip 4 extending in the vertical direction, which can slide into the mounting groove 6 connected to the guardrail piece 2.

[0026] like Figure 9 and Figure 10 As shown, the length of guardrail panel 2 is available in several sizes as needed, with smaller sizes being more convenient for transportation and installation, such as... Figure 7 As shown, when the distance between two adjacent posts 1 is relatively large (for example, a standard distance of 3 meters), several small guardrail panels 2 can be connected end to end and spliced ​​together for installation. During installation, one worker can easily complete the task without the need for external tools such as forklifts or cranes. At bends or at the end of the road, when the remaining railing length is less than 3 meters, small guardrail panels 2 can also be installed directly without the need for custom-made ones.

[0027] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
