[0034] Please refer to Figures 1 to 9 A guardrail support device A for improving road life includes: a column 100, a base 200, a plurality of mounting blocks 300 and a plurality of first connecting members 400. Figure 2 As shown, the roadbed B is located on both sides of the road surface C, and the pillars 100 can be fixed on the roadbed B.

[0035] The plurality of first connecting members 400 correspond to the plurality of mounting blocks 300 one by one. The first connecting members 400 sequentially pass through the column 100 and the base 200 and are connected to the corresponding mounting blocks 300 to mount the base 200 and the mounting blocks 300 on the column 100, wherein:

[0036] The base 200 includes a base body 210 and a first protrusion 220 disposed on the base body 210. Figure 5 As shown, the first protrusion 220 may be located in the middle area of ​​the base body 210 , the first protrusion 220 is located on a side of the base body 210 away from the column 100 , and the first protrusion 220 is extended in the vertical direction.

[0037] A first groove 301 is formed on the first side of the mounting block 300, and a plurality of guardrail connectors 600 are formed on the second side of the mounting block 300. The guardrail connectors 600 are used to mount the corrugated guardrail 800. The first side of the mounting block 300 and the second side of the mounting block 300 are arranged opposite to each other, and the plurality of mounting blocks 300 are arranged in a vertical direction and buckled on the first protrusion 220 through the corresponding first grooves 301.

[0038] It should be noted that the first connector 400 may be a bolt structure, the bolt head of the first connector 400 may be in limited contact with the column 100, and the screw of the first connector 400 may sequentially pass through the column 100 and the base 200 and be threadedly connected with the corresponding mounting block 300. Of course, the first connector 400 may also be other structures, for example, the first connector 400 may be a connecting pin, which may sequentially pass through the column 100, the base 200 and the mounting block 300, and the two ends of the connecting pin extend out of the column 100 and the mounting block 300 respectively, and bend, and the bent portion may be limitedly matched with the corresponding column 100 and the mounting block 300 to install the base 200 and the mounting block 300 on the column 100. Among them, the present invention does not specifically limit the position where the first connector 400 passes through the base 200 and the position where it is connected with the mounting block 300.

[0039] The guardrail support device A for improving the life of a road disclosed in the present invention is provided with a base 200, a plurality of mounting blocks 300 and a plurality of first connectors 400, so that the first connectors 400 sequentially pass through the column 100 and the base 200 and are connected with the corresponding mounting blocks 300, so that the base 200 and the mounting block 300 are installed on the column 100, and the base 200 is provided with a structure having a first protrusion 220 extending in the vertical direction, and the mounting block 300 is provided with a structure having a first groove 301 on the first side and a plurality of guardrail connectors 600 on the other side, so that the plurality of mounting blocks 300 are buckled on the first protrusion 220 through the corresponding first grooves 301, so that the installation of the mounting block 300 is more stable. Each mounting block 300 can be installed with a single-layer corrugated guardrail 800 through the guardrail connector 600, and the plurality of mounting blocks 300 distributed in the vertical direction can be installed with a plurality of single-layer corrugated guardrails 800, so that the plurality of single-layer corrugated guardrails 800 are spliced ​​in the vertical direction to form the entire guardrail. Since the single-layer corrugated guardrail 800 is easier to bend during installation, the corrugated guardrail 800 can be installed layer by layer, thereby making installation easier when encountering various bends and curves.

[0040] When a car collides with the corrugated guardrail 800, in order to provide a buffer force to improve the anti-collision performance, optionally, the mounting block 300 and the first protrusion 220 can move relative to each other in the buckling direction of the mounting block 300, and the buckling direction is perpendicular to the vertical direction. The guardrail support device A for improving the road life can also include a plurality of elastic members 500, and an elastic member 500 can be provided between the bottom wall of the first groove 301 of each mounting block 300 and the top of the first protrusion 220, and the elastic member 500 can be elastically supported between the bottom wall of the first groove 301 and the top of the first protrusion 220, and the elastic member 500 is in a compressed state.

[0041] The present invention arranges the mounting block 300 and the first protrusion 220 as a relatively movable structure in the buckling direction of the mounting block 300, and an elastic member 500 is arranged between the bottom wall of the first groove 301 of each mounting block 300 and the top of the first protrusion 220, so that when a car collides with the corrugated guardrail, the corrugated guardrail and the mounting block 300 as a whole can have a certain buffer distance along the buckling direction of the mounting block 300 under the elastic force of the elastic member 500, thereby providing a better buffering force for the car, thereby improving the overall anti-collision performance of the guardrail.

[0042] Specifically, the elastic member 500 may be elastic rubber, elastic foam, etc., and the present invention does not specifically limit the type of the elastic member 500 .

[0043] Optionally, the elastic member 500 may be a spring, the first connecting member 400 may sequentially pass through the column 100 , the base body 210 and the first protrusion 220 to be connected to the corresponding mounting block 300 , and the spring may be sleeved on the first connecting member 400 .

[0044] The present invention connects the first connecting member 400 through the column 100, the base body 210 and the first protrusion 220 with the corresponding mounting block 300 in sequence, so that the first connecting member 400 can be inserted into the spring, so that when the car collides with the corrugated guardrail 800 and causes the spring to be compressed, the spring can be prevented from being squeezed and deformed and popping out, thereby allowing the spring to provide reliable buffering force.

[0045] In an optional embodiment, the mounting block 300 may include a mounting block body 310 and a second protrusion 320, the mounting block body 310 may be provided with a first groove 301, the second protrusion 320 may be provided on the mounting block body 310 and located on the side away from the first groove 301, and the tops of the mounting block body 310 and the second protrusion 320 may be provided with a guardrail connector 600, so that when the corrugated guardrail 800 is installed, the trough of the corrugated guardrail 800 can be connected to the guardrail connector 600 located on the mounting block body 310, and the crest of the corrugated guardrail 800 can be connected to the guardrail connector 600 located on the top of the second protrusion 320, so that the crest and trough of the corrugated guardrail 800 are both installed on the mounting block 300 through the guardrail connector 600, thereby making the installation of the corrugated guardrail 800 more stable.

[0046] In order to improve the overall buffering capacity of the guardrail, optionally, the mounting block body 310 may include a bottom plate 311 and two first side plates 312 arranged at intervals on the bottom plate 311, the two first side plates 312 may enclose the first groove 301 with the bottom plate 311, and the two first side plates 312 and the bottom plate 311 may be an integrated structure. The bottom plate 311 and the first side plates 312 may both be hollow structures, and the bottom plate 311 is provided with a first avoidance hole 311a at a position opposite to the first groove 301. The mounting block 300 may also include a first cushion block 330, the first cushion block 330 may be provided with a first threaded hole, the first cushion block 330 may be arranged inside the bottom plate 311, and the first threaded hole may be opposite to the first avoidance hole 311a, and the first connector 400 may pass through the column 100 and the base 200 in sequence and be threadedly connected to the first threaded hole.

[0047] It should be noted that when the first connecting member 400 rotates, the first cushion block 330 does not rotate accordingly. By rotating the first connecting member 400, the first cushion block 330 can drive the mounting block 300 as a whole to move in the buckling direction of the mounting block 300, so that the mounting block 300 can drive the corrugated guardrail to move in the buckling direction through the guardrail connecting member 600. By adjusting the multiple first connecting members 400 distributed along the vertical direction on the same column 100, the distances between the multiple mounting blocks 300 and the base 200 in the buckling direction can be different (the multiple mounting blocks 300 on the same column 100 have different distances from the base 200 in the buckling direction, and the mounting blocks 300 corresponding to the same layer of corrugated guardrails 800 of adjacent columns 100 have different distances from the base 200 in the buckling direction), so that the multiple layers of corrugated guardrails distributed along the vertical direction are staggered in the buckling direction, so that when a car collides with the corrugated guardrail 800, the car first contacts the outermost layer of corrugated guardrail 800 in the buckling direction, and the outermost layer of corrugated guardrail 800 contacts the next layer of corrugated guardrail 800 after deformation, and so on, so that the multiple layers of corrugated guardrail 800 distributed along the vertical direction can provide multiple buffers for the car, thereby effectively improving the overall buffering capacity of the guardrail, and also avoiding excessive rigid contact between the car and the corrugated guardrail 800, thereby improving the overall protective performance of the guardrail.

[0048] Optionally, the mounting block body 310 may further include two second side plates 313, the second side plates 313 may be a hollow structure, the two second side plates 313 may be arranged on the bottom plate 311, and may be respectively arranged on the side of the two first side plates 312 away from the first groove 301. The bottom plate 311, the two first side plates 312 and the two second side plates 313 may be an integrated structure. The two second side plates 313 may surround two second grooves 302 with the two first side plates 312. The mounting block 300 may further include a second cushion block 340, the two second grooves 302 may be provided with a second cushion block 340, the second cushion block 340 may be provided with a second threaded hole, the bottom plate 311 may be provided with a second avoidance hole at a position opposite to the second groove 302, the guardrail connector 600 may be a bolt structure, and the guardrail connector 600 corresponding to the mounting block body 310 may be threadedly connected to the second threaded hole through the second avoidance hole.

[0049] The present invention can not only improve the overall strength of the mounting block body 310 by providing the second side plate 313, but also form two second grooves 302 with the two first side plates 312, so that the second pad 340 can be arranged in the second groove 302, thereby making the installation of the second pad 340 more stable. The second pad 340 is provided with a second threaded hole, so that the guardrail connector 600 can pass through the second avoidance hole on the bottom plate 311 and be threadedly connected to the second threaded hole, so that the installation of the guardrail connector 600 can be achieved. Moreover, when the threaded cooperation between the guardrail connector 600 and the second threaded hole fails, only the second pad 340 or the guardrail connector 600 can be replaced, so there is no need to replace the entire mounting block 300, thereby saving maintenance costs.

[0050] Optionally, a third threaded hole may be formed at the top of the second protrusion 320 , and the guardrail connector 600 corresponding to the second protrusion 320 may be threadedly connected to the third threaded hole, thereby making the connection of the guardrail connector 600 to the top of the second protrusion 320 easier.

[0051] Optionally, a plurality of guardrail connectors 600 may be provided at intervals on the top of the mounting block body 310 and the second protrusion 320 in the first horizontal direction. It should be noted that the buckling direction may be the second horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction.

[0052] The present invention arranges a plurality of guardrail connectors 600 at intervals along the first horizontal direction on the top of the mounting block body 310 and the second protrusion 320, so that when the plurality of guardrail connectors 600 of each mounting block 300 are installed with the same corrugated guardrail 800, the installation of the corrugated guardrail 800 can be made more stable. Moreover, the plurality of guardrail connectors 600 of each mounting block 300 can also splice a plurality of corrugated guardrails 800 on the same layer, thereby ensuring the continuity of the corrugated guardrail 800.

[0053] Optionally, there may be intervals between the multiple mounting blocks 300 , so as to avoid the multiple mounting blocks 300 being unable to be mounted on the same base 200 due to factors such as processing errors or installation errors of the mounting blocks 300 .

[0054] Optionally, the side of the base body 210 facing the column 100 may have a slot 211, which may extend in the vertical direction and may be buckled on the column 100. The guardrail support device A for improving the road life may also include a second connecting member 700, which may pass through the side wall of the slot 211 and the column 100.

[0055] The present invention configures the base body 210 to have a slot 211 on one side facing the column 100 so that the slot 211 can be buckled on the column 100, and the second connecting member 700 penetrates the side wall of the slot 211 and the column 100, making the installation of the base 200 more stable.

[0056] In order to facilitate the installation of the corrugated guardrail 800, a plurality of snap-in protrusions 810 may be provided at intervals on the side edge of the corrugated guardrail 800. Figure 7 As shown, when installing the corrugated guardrail 800 on various bends and curves, the lowest corrugated guardrail 800 can be installed on the corresponding mounting block 300 first, and then the upper corrugated guardrail 800 can be installed. When installing the upper corrugated guardrail 800, one end of the corrugated guardrail 800 can be installed on the mounting block 300 first, and the installer then bends the corrugated guardrail 800 along the bending direction of the bend and curve. During the bending process, the multiple snap-in protrusions 810 of the upper corrugated guardrail 800 can be snap-into the top of the lower corrugated guardrail 800 in sequence, thereby preventing the already bent portion of the corrugated guardrail 800 from rebounding, which is equivalent to bending the corrugated guardrail 800 section by section, making the bending process of the corrugated guardrail 800 relatively easy.

[0057] The present invention takes a three-layer corrugated guardrail 800 as an example to schematically illustrate the installation process of the corrugated guardrail 800. The three-layer corrugated guardrail 800 may include an upper guardrail 800a, a middle guardrail 800b and a lower guardrail 800c, and each section of the upper guardrail 800a, the middle guardrail 800b and the lower guardrail 800c are equal in length, and the length may extend between four road life-prolonging guardrail support devices A.

[0058] The first step is to install the lower guardrail 800c. The two opposite ends of the two adjacent lower guardrails 800c can be installed on the lowest mounting block 300 of the same road life-prolonging guardrail support device A. Figure 7 As shown, one end of the first lower guardrail 800c1 and one end of the second lower guardrail 800c2 are installed on the first guardrail support device ( Figure 7 The guardrail support device A for improving the road life is the same mounting block 300 of the first guardrail support device).

[0059] In the second step, the middle guardrail 800b is installed. The two opposite ends of the two adjacent middle guardrails 800b can be installed on the middle layer mounting block 300 of the same road life extension guardrail support device A. The joint of the two adjacent middle guardrails 800b and the joint of the two adjacent lower guardrails 800c are not on the same road life extension guardrail support device A. Fig. 9 As shown, one end of the first intermediate guardrail 800b1 and one end of the second intermediate guardrail 800b2 are installed on the second guardrail support device ( Fig. 9 The guardrail support device A for improving the road life is the same mounting block 300 of the second guardrail support device).

[0060] In the third step, the upper guardrail 800a is installed. The two opposite ends of the two adjacent upper guardrails 800a can be installed on the uppermost mounting block 300 of the same road life extension guardrail support device A. The joints of the two adjacent upper guardrails 800a and the two adjacent lower guardrails 800c and the two adjacent middle guardrails 800b are not on the same road life extension guardrail support device A. Figure 8 As shown, one end of the first upper guardrail 800a1 and one end of the second upper guardrail 800a2 are installed on the third guardrail support device ( Figure 8 The guardrail support device A for improving the road life is the same mounting block 300 of the third guardrail support device).

[0061] The fourth step is to adjust the first connecting member 400 on the same road life-prolonging guardrail support device A so that the upper guardrail 800a, the middle guardrail 800b and the lower guardrail 800c installed on the same road life-prolonging guardrail support device A are staggered in the buckling direction of the mounting block 300. Figure 7 The lower guardrail 800c of the first guardrail support device has been adjusted to be staggered with the middle guardrail 800b and the upper guardrail 800a in the buckling direction of the mounting block 300, such as Figure 8 The upper guardrail 800a of the second guardrail support device has been adjusted to be staggered with the middle guardrail 800b and the lower guardrail 800c in the buckling direction of the mounting block 300, such as Fig. 9 The middle guardrail 800b of the third guardrail supporting device has been adjusted to be staggered with the upper guardrail 800a and the lower guardrail 800c in the buckling direction of the mounting block 300.

[0062] When a car collides with the corrugated guardrail 800, the car first contacts the outermost layer of the corrugated guardrail 800 in the buckling direction, and the outermost layer of the corrugated guardrail 800 contacts the next layer of the corrugated guardrail 800 after being deformed, and so on. The multiple layers of corrugated guardrail 800 distributed along the vertical direction can provide multiple buffers for the car, thereby effectively improving the overall buffering capacity of the guardrail, and avoiding excessive rigid contact between the car and the corrugated guardrail 800, thereby improving the overall protection performance of the guardrail.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
