Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of highway safety protection equipment, specifically relating to a column counterweight and a column-type guardrail. Background Technology
[0002] Highway guardrails are safety facilities installed on the edge of roads or in the central divider. Their main purpose is to prevent vehicles from running off the road after losing control and to reduce collision damage in the event of a traffic accident.
[0003] Existing corrugated beam guardrails typically use cylindrical posts. During highway construction, the posts need to be driven into the soil when installing the guardrails. However, soil clods are often squeezed into the steel pipes, making the driving process difficult. Chinese patent document CN222834799U (202421784237.9) discloses a novel liftable corrugated beam guardrail. This guardrail's posts, aided by wedge-shaped heads, facilitate driving into the soil and replacement. When replacing the corrugated beams, the posts are easier to remove because the soil was not squeezed into them during driving. Furthermore, it is not necessary to remove soil from inside the steel pipe posts when using them. However, to ensure the posts' stability, they still need to be driven into the ground at a considerable depth, requiring longer posts, increasing costs and the difficulty of retrieving and recovering them. Utility Model Content
[0004] The purpose of this invention is to design a post counterweight and a post-type guardrail. The post counterweight has a first and a second stepped platform at both ends that can be spliced together, and a vertical insertion hole for the post is set on the first and the second stepped platform. This can serve as a counterweight for the guardrail post, reducing the depth at which the post is driven into the ground. In addition, the post can connect two adjacent post counterweights together, making the guardrail a more stable whole and enhancing its impact resistance.
[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a column counterweight block, comprising a strip-shaped body; The strip-shaped body is provided with a first step platform and a second step platform at both ends, respectively. Both the first and second step platforms are provided with vertical through-holes for inserting columns. The first step platform has its step surface facing upwards, while the second step platform has its step surface facing downwards.
[0006] Preferably, the longitudinal section of the strip-shaped body is rectangular or square. The bottom surface of the first stepped platform is flush with the lower end surface of the strip-shaped body; The bottom surface of the second step platform is flush with the top surface of the strip-shaped body. Since the bottom surface of the first step platform is flush with the bottom surface of the strip-shaped body, and the bottom surface of the second step platform is flush with the top surface of the strip-shaped body, it is ensured that after the first and second step platforms of two adjacent column counterweights are spliced together, the bottom surface of the column counterweight is in close contact with the placement plane.
[0007] Preferably, in this invention, the sum of the thicknesses of the first and second stepped platforms is less than or equal to the thickness of the strip-shaped body. Because the sum of the thicknesses of the first and second stepped platforms is less than or equal to the thickness of the strip-shaped body, after the first and second stepped platforms of two adjacent column counterweights are joined together, the two adjacent column counterweights will not interfere with each other in the thickness direction, ensuring the stability of the column counterweights.
[0008] Preferably, the thickness of the first step platform and the thickness of the second step platform are equal to the thickness of the strip-shaped body, thereby ensuring that the counterweights of two adjacent columns are stably spliced together to form a stable guardrail mounting base.
[0009] This utility model also discloses a post-type guardrail, which utilizes the above-mentioned post counterweight, including a corrugated plate and a post; The multiple column counterweights are arranged linearly, and the first and second steps of two adjacent column counterweights are spliced together. The lower end of the column passes through the column insertion hole on the first and second step platforms; The corrugated plate is installed on the upper end of the column.
[0010] Preferably, in this invention, the cross-section of the column is circular, and the column insertion hole is cylindrical. Since both the column and the column insertion hole have circular cross-sections, the column counterweight can rotate around the column, adjusting the angle between adjacent counterweights to suit protection on curved roads.
[0011] Preferably, this utility model also includes an intermediate connecting frame, which is detachably mounted on the column by bolts; The corrugated plate is detachably mounted on the intermediate connecting frame by bolts; Preferably, the corrugated plates are symmetrically arranged on both sides of the column; Preferably, the column is provided with two or more layers of corrugated plates from top to bottom. The column and the corrugated plates are connected together by an intermediate connecting frame, so that the corrugated plates can be used for columns of different shapes.
[0012] Preferably, in this invention, the column counterweight is placed above the road surface or partially buried below the ground. Placing the column counterweight above the road surface or partially buried below the ground facilitates quick insertion of the column into the column insertion hole, simplifying construction; the partial burial of the column counterweight below the ground further enhances the stability of the column base.
[0013] In a preferred embodiment of this invention, the column counterweight is made of precast concrete. The column counterweight is prefabricated in batches in advance and can be assembled on site, which helps to improve construction efficiency and reduce production costs.
[0014] Preferably, the lower end of the column is provided with a tapered tip. By providing a tapered tip at the lower end of the column, the resistance to driving the column into the ground can be reduced.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the first and second stepped platforms at both ends of the column counterweight block can be spliced together, and the lower end of the column can pass through the column insertion holes on the first and second stepped platforms to connect two adjacent column counterweight blocks together. The column counterweight block can enhance the stability of the column and improve the overall impact resistance of the guardrail.
[0016] The post-type guardrail of this utility model has a counterweight block at the bottom, which reduces the driving depth of the post while ensuring the stability of the post. Furthermore, the post connects the counterweight block together with the corrugated plate above, making the post-type guardrail a whole, with better stability and impact resistance.

Conical sharp angle. Detailed Implementation
[0018] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.
[0019] In this embodiment, the bottom surfaces of the first step platform 11 and the second step platform 12 are arranged opposite to the step surface.
[0020] Example 1 like Figure 1 and Figure 2 As shown, a column counterweight includes a strip-shaped body 1.
[0021] The strip-shaped body 1 has a first stepped platform 11 and a second stepped platform 12 at both ends.
[0022] Both the first step platform 11 and the second step platform 12 are provided with vertical through-holes 13 for inserting columns.
[0023] The first step platform 11 is positioned with its step surface facing upwards, while the second step platform 12 is positioned with its step surface facing downwards.
[0024] The longitudinal section of the strip-shaped body 1 is rectangular or square, that is, the strip-shaped body 1 is a cuboid.
[0025] The bottom surface of the first stepped platform 11 is flush with the lower end surface of the strip-shaped body 1.
[0026] The bottom surface of the second step platform 12 is flush with the upper surface of the strip body 1. The sum of the thickness of the first step platform 11 and the thickness of the second step platform 12 is less than or equal to the thickness of the strip body 1.
[0027] In this embodiment, the sum of the thickness of the first stepped platform 11 and the thickness of the second stepped platform 12 is equal to the thickness of the strip-shaped body 1.
[0028] like Figure 3 As shown, a post-type guardrail utilizes the aforementioned post counterweight block, including a corrugated plate 3 and a post 2.
[0029] The multiple column counterweights are arranged linearly, and the first step 11 and the second step 12 of two adjacent column counterweights are spliced together.
[0030] The lower end of the column 2 passes through the column insertion hole 13 on the first step platform 11 and the second step platform 12.
[0031] The corrugated plate 3 is installed on the upper end of the column 2. The two ends of the corrugated plate 3 are detachably mounted on two adjacent columns 2. The corrugated plate 3 can be installed on only one side of the two columns 2, or one corrugated plate 3 can be installed on each side of the two columns 2. Preferably, the corrugated plates 3 are symmetrically arranged on the front and rear sides of the columns 2.
[0032] In this embodiment, only one layer of corrugated plate 3 can be set on the top of the column 2. In order to improve the protection performance, two or more layers of corrugated plates 3 can also be set on the column 2 from top to bottom.
[0033] The counterweight block of the column is made of precast concrete.
[0034] The column 2 has a circular cross-section, and the column insertion hole 13 is cylindrical. The diameters of the column 2 and the column insertion hole 13 are matched.
[0035] The post-type guardrail also includes an intermediate connecting frame 4, which is detachably mounted on the post 2 by bolts.
[0036] The corrugated plate 3 is detachably mounted on the intermediate connecting frame 4 by bolts. Both the column 2 and the intermediate connecting frame 4 are provided with bolt mounting holes. The intermediate connecting frame 4 is made of sheet metal by stamping, and can also be set in an annular cylindrical shape to play a buffering role.
[0037] The counterweight block of the column is placed above the road surface or partially buried below the ground. Specifically, during construction, a foundation construction surface is prepared on the roadside, that is, the road surface is leveled to ensure that the counterweight block of the column is placed stably on the road surface. Then, the column 2 is driven into the ground through the column insertion hole 13. In order to improve the stability of the counterweight block, soil can be used to partially bury the bottom of the counterweight block.
[0038] Example 2 like Figure 4 As shown, the lower end of the column 2 is provided with a conical tip 21, which can effectively reduce resistance when the column 2 is driven into the ground.
