Description

Technical Field

[0001] The utility model relates to the technical field of municipal roads, in particular to a fast-assembly type roadside guardrail. Background Art

[0002] Road guardrails are facilities installed on both sides of the road or on the central dividing strip. Their main function is to prevent vehicles and pedestrians from deviating from the road and to prevent traffic accidents from causing damage to the surrounding environment.

[0003] However, most of the existing guardrails are fixed structures. Once damaged, subsequent replacement is more troublesome. Once a fixed guardrail is damaged, the entire guardrail can only be disassembled and replaced, resulting in increased costs. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a fast-assembly roadside guardrail with modular arrangement, which can be quickly installed and disassembled to solve the problems raised in the above-mentioned background technology.

[0005] The utility model is realized through the following technical scheme: a quick-assembly roadside guardrail, comprising a plurality of guide rails and guardrail brackets, the bottom surfaces of the guardrail brackets are all installed with base plates, the guide rails are arranged horizontally, the guide rails are all connected, the guardrail brackets are all slidably installed in the guide rails through the base plates, the outer sides of the guide rails are all installed with fixed seats through hinges, the fixed seats are all provided with a plurality of axial holes, the outer side surfaces of the guide rails are all provided with positioning holes at the positions opposite to the axial holes, the outer sides of the fixed seats are all provided with cross plates, the positions of the cross plates are all installed with positioning columns at the positions opposite to the axial holes, and the other ends of the positioning columns are all inserted into the corresponding positioning holes through the axial holes.

[0006] As a preferred technical solution, first screw holes are provided at both ends of the horizontal plate, second screw holes are provided on the outer side of the fixing seat opposite to the first screw holes, and bolts are threadedly connected in the first screw holes and the second screw holes opposite to each other.

[0007] As a preferred technical solution, a plurality of straight slots are provided on a side of the fixing seat away from the guide rail.

[0008] As a preferred technical solution, adjacent bottom plates are arranged to abut against each other.

[0009] As a preferred technical solution, the guardrail brackets are all arranged in a "U"-shaped structure.

[0010] As a preferred technical solution, the length of the cross plate matches the width of the fixing seat, and the cross plate and the positioning column are both made of steel.

[0011] As a preferred technical solution, the added length of the inner bottom plates of each guide rail matches the length of the guide rail.

[0012] As a preferred technical solution, the guide rail is arranged flush with the bottom surface of the fixing seat.

[0013] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and the guardrail bracket is slidably arranged in the guide rail through the bottom plate. Once damaged, it can be directly replaced by sliding, and only the damaged guardrail bracket can be replaced, avoiding the entire replacement and reducing costs. It can also be quickly disassembled by dislocation, which increases convenience. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a quick-assembly roadside guardrail of the utility model comprises a plurality of guide rails 1 and guardrail brackets 3, bottom plates 2 are installed on the bottom surfaces of the guardrail brackets 3, the guide rails 1 are arranged horizontally, the guide rails 1 are connected, the guardrail brackets 3 are slidably installed in the guide rails 1 through the bottom plates 2, the outer sides of the guide rails 1 are installed with fixing seats 4 through hinges, a plurality of axial holes are provided on the fixing seats 4, positioning holes are provided at the outer sides of the guide rails 1 facing the axial holes, cross plates 5 are provided on the outer sides of the fixing seats 4, positioning columns 8 are installed at the cross plates 5 facing the axial holes, and the other ends of the positioning columns 8 are inserted into the corresponding positioning holes through the axial holes.

[0023] In this embodiment, first screw holes are provided at both ends of the transverse plate 5, and second screw holes 9 are provided on the outer side of the fixing seat 4 opposite to the first screw holes. Bolts 7 are threadedly connected in the first screw holes and the second screw holes 9 opposite to each other.

[0024] In this embodiment, a plurality of straight slots 6 are provided on a side of the fixing seat 4 away from the guide rail 1 .

[0025] In this embodiment, adjacent bottom plates 2 are arranged to abut against each other. After the bottom plates are slidably arranged in the guide rails, the bottom plates can abut against each other to increase the tightness and stability between the bottom plates.

[0026] In this embodiment, the guardrail brackets 3 are all arranged in a "U"-shaped structure, which reduces the material consumption and cost.

[0027] In this embodiment, the length of the transverse plate 5 matches the width of the fixing seat 4, and the transverse plate 5 and the positioning column 8 are both made of steel material, which increases the firmness and service life.

[0028] In this embodiment, the added length of the bottom plate 2 inside each guide rail 1 matches the length of the guide rail 1, so that the bottom plate can slide just inside the guide rail. After the guide rails collide, the bottom plates between adjacent guide rails are arranged to collide, thereby increasing overall stability.

[0029] In this embodiment, the guide rail 1 is flush with the bottom surface of the fixing seat 4, so that the fixing seat and the guide rail can be stably placed on the road surface.

[0030] During installation, expansion bolts or other fixings can be prepared, and the fixings can pass through the straight grooves to fix the fixing seats on both sides of the road. After fixing, the guide rails just collide with each other, and the bottom plate can be limited by the guide rails set in contact. Among them, the end face sealing arrangement of the outermost guide rail makes it impossible for the bottom plate to slide out along the outermost guide rail. After any guardrail bracket is damaged, the bolts can be screwed out. After the fixation of the bolts is lost, the cross plate can be pulled outward, and the movement of the cross plate synchronously drives the positioning column. After the positioning column is moved out of the positioning hole, the guide rail will lose its obstruction, so that the guide rail can rotate upward with the hinge as the center until the guide rail is misaligned with the adjacent guide rail. At this time, the bottom plate can slide outward along the two ends of the guide rail, which is convenient for the disassembly and replacement of the guardrail bracket, avoids the entire replacement, reduces the cost, and can be quickly disassembled by misalignment, which increases convenience.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
