[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The purpose of this utility model is to provide a steel guardrail to solve the problems existing in the prior art, provide a steel guardrail structure that is easy to install, and improve the installation efficiency of steel guardrails.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-4 As shown, this utility model provides a steel guardrail, including: a post 1 with post connecting plates 2 on both sides of its bottom; a fixing plate 4 located on both sides of the post 1, the fixing plate 4 including a ground fixing end 41 and a cantilever end 42; the ground fixing end 41 is fixedly connected to the ground, which can be fixed by welding or bolts; the cantilever end 42 extends to cover the upper surface of the post connecting plate 2, and has a vertical through threaded hole, in which a vertical bolt is installed, the vertical bolt passing through the vertical through threaded hole and abutting against the upper surface of the post connecting plate 2; a clamp assembly 7 and a crossbeam 6, the clamp assembly 7 being fixed to the side wall of the post 1 for fixing the crossbeam 6 to the side wall of the post 1.

[0033] When installing the steel guardrail, insert the post connecting plate 2 into the gap between the fixing plate 4 and the ground, so that the cantilever end 42 on the fixing plate 4 covers the upper surface of the post connecting plate 2. Then, screw the vertical bolt into the vertical threaded hole on the upper surface of the cantilever end 42 of the fixing plate 4. The vertical bolt firmly presses the post connecting plate 2 against the ground. This completes the installation of the steel guardrail post 1. There is no need to pre-drill threaded holes in the ground, there is no hole alignment, and there is no misalignment between the bolt and the threaded hole. The installation is very convenient and greatly improves the installation efficiency of the steel guardrail.

[0034] As an example of an implementable approach, such as Figures 2-4 As shown, the fixing plate 4 also includes a limiting part 43, which is connected to the end of the cantilever end 42 near the side wall of the column 1. The limiting part 43 extends upward along the side wall of the column 1 and is provided with a lateral through-threaded hole. A lateral bolt is provided in the lateral through-threaded hole, which passes through the lateral through-threaded hole and abuts against the side wall of the column 1. The upper surface of the fixing plate 4 may also be provided with longitudinal reinforcing ribs 9 connecting the cantilever end 42 and the limiting part 43 to improve the strength of the fixing plate 4. The fixing plates 4 are provided one-to-one with the columns 1, and at least two longitudinal reinforcing ribs 9 are provided in any fixing plate 4. By providing the limiting part 43, the lateral support of the fixing plate 4 to the column 1 is greatly increased, improving the stability of the steel guardrail.

[0035] As an example of an implementable approach, such as Figures 1-2 As shown, the bottom of the post 1 is also provided with a groove 3; the steel guardrail also includes a protrusion 5 that can be embedded in the groove 3. The lower part of the protrusion 5 is fixed to the ground and can be fixed by welding or bolts. The upper part forms a tenon-and-mortise fit with the groove 3. The protrusion 5 can be a precast concrete block or a steel component. The longitudinal section of the protrusion 5 can be an inverted trapezoidal structure. The longitudinal section refers to the section perpendicular to the direction of installation of the protrusion 5 and the groove 3. During installation, the post connecting plate 2 is slid into the gap between the fixing plate 4 and the ground. At the same time, the protrusion 5 also completes the tenon-and-mortise fit with the groove 3. The tenon-and-mortise fit between the protrusion 5 and the groove 3 further increases the stability and impact resistance of the steel guardrail.

[0036] As an example of an implementable approach, such as Figures 1-4 As shown, the clamp assembly 7 includes a first half-ring welded to the post 1, a second half-ring hinged to the first half-ring, and a bolt fastening mechanism for locking the free ends of the first and second half-rings. An elastic washer, made of silicone or rubber, can also be provided on the inner wall of the clamp assembly 7 to further stabilize the crossbeam 6 and prevent axial sliding of the crossbeam 6. At least three sets of clamp assemblies 7 are arranged at intervals along the height of the post 1. By setting the clamp assembly 7, the need for drilling operations when connecting the crossbeam 6 with bolts is avoided, improving the installation efficiency of the steel guardrail.

[0037] The clamp assembly 7, consisting of the first and second half-rings, is not necessarily circular; it needs to be adapted to the cross-sectional shape of the beam 6. Figure 4 As shown, when the crossbeam 6 is a square tube, the corresponding clamp assembly 7, composed of the first half-ring and the second half-ring, is also a square ring.

[0038] As an example of an implementable approach, such as Figure 3 As shown, it also includes a crossbeam connecting plate 8, which symmetrically covers the joint of adjacent crossbeams 6. The axial connection of adjacent crossbeams 6 is achieved by through bolts, which avoids the problem in some crossbeam 6 installation techniques where the crossbeams 6 need to be moved axially when the sleeve is used to connect two adjacent crossbeams 6, thus improving the convenience of disassembling and assembling the steel guardrail crossbeams 6.

[0039] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
