Description
Technical Field
[0001] This utility model relates to the field of road construction facilities technology, and in particular to a guardrail base. Background Technology
[0002] With the continuous increase in national infrastructure investment, highways will also undergo lane reconstruction and expansion projects as well as road maintenance. However, due to the special nature of highways, lane reconstruction and expansion projects are usually carried out by closing only one lane or multiple lanes. Therefore, if vehicles traveling in other lanes accidentally enter the construction area due to overtaking, lane changing, or inclement weather, it will pose a significant safety threat to construction workers and equipment.
[0003] Currently, during the lane reconstruction and expansion of highways, the main method to improve safety in the construction area is to install guardrails around the perimeter. In existing technology, guardrails can be divided into two types: one type includes connected posts and beams, with the posts directly fixed to the road surface or connected to the road surface via other connecting structures; however, both methods damage the road surface. The other type includes a base and connected posts and beams, with the posts installed on the base, which is placed on the ground.
[0004] When setting up the base, it is usually necessary to add an additional counterweight inside the base and connect it to the base via connecting components to improve the stability of the base and ensure that the guardrail in the construction area meets the corresponding safety level requirements. However, this will increase the cost of the base and also increase the complexity of its assembly.
[0005] Therefore, how to improve the structural simplicity of the base and reduce its cost while meeting the safety requirements of the guardrail has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] This utility model provides a guardrail base to improve the structural simplicity of the guardrail base and reduce its cost.
[0007] This utility model provides a guardrail base for mounting posts. The guardrail base includes at least two adjacent bodies. Along the axial direction of the post, a portion of the body is used to abut against the road surface. One side wall of each body has a first protrusion, and the other side wall has a second protrusion; the first and second protrusions are opposite to each other. Along the axial direction of the post, the first protrusion includes a first surface and a second surface disposed opposite to each other. The second surface is used to abut against the road surface, and a gap exists between the second protrusion and the road surface to accommodate at least a portion of the first protrusion of the adjacent body. The second protrusion of one body is connected to the first protrusion of the adjacent body via the post.
[0008] The guardrail base provided by this utility model features a first and second protrusion that overlap between two adjacent bodies, and a stable connection between them achieved through a column. Simultaneously, the second surface of the first protrusion and the bottom surface of the body both abut against the road surface. This allows the assembled guardrail to meet safety requirements while effectively simplifying the structure of the guardrail base and reducing its cost.
[0009] In one possible implementation of this invention, along the axial direction of the column, the second protrusion includes a third surface and a fourth surface disposed opposite to each other. When the second protrusion of the main body is connected to the first protrusion of an adjacent main body via the column, the fourth surface of the second protrusion abuts against the first surface of the first protrusion of the adjacent main body. This simplifies the structure of the guardrail base while effectively improving the connection stability of two adjacent main bodies.
[0010] In one possible implementation of this invention, when the second protrusion of the main body is connected to the first protrusion of an adjacent main body via a column, the sidewall of the first protrusion abuts against the sidewall of the adjacent main body in the direction away from the sidewall of the main body. This simplifies the structure of the guardrail base while effectively improving the connection stability of the two adjacent main bodies.
[0011] In one possible implementation of this invention, when the second protrusion of the main body is connected to the first protrusion of an adjacent main body via a column, the sidewall of the second protrusion abuts against the sidewall of the adjacent main body in the direction away from the sidewall of the main body. This simplifies the structure of the guardrail base while effectively improving the connection stability between the two adjacent main bodies.
[0012] In one possible implementation of this invention, the first protrusion further includes a first blind hole, and the second protrusion includes a first through hole. The first blind hole of the first protrusion is coaxial with the first through hole of the second protrusion of the adjacent body, and the coaxial first through hole and first blind hole are used for sequential insertion with the post. This simplifies the structure of the guardrail base and reduces its cost while meeting the safety level requirements of the guardrail base.
[0013] In one possible implementation of this invention, the main body includes a second blind hole located between the first protrusion and the second protrusion, and the second blind hole is used to insert a post. Since adjacent posts are connected by beams, this helps to further improve the overall strength of the guardrail.
[0014] In one possible implementation of this invention, the body further includes a first reinforcing rib, which surrounds the second blind hole along its circumference. This helps to further improve the structural reliability of the guardrail base.
[0015] In one possible implementation of this utility model, the main body further includes a second reinforcing rib, a portion of which extends out of the side wall of the main body along the direction from the first protrusion to the second protrusion, and the portion of the second reinforcing rib extending out of the side wall of the main body is inserted into the second protrusion. This is beneficial for improving the overall strength of the guardrail base.
[0016] In one possible implementation of this utility model, the body further includes a third reinforcing rib, a portion of which extends out of the side wall of the body along the direction from the second protrusion to the first protrusion, and the portion of the third reinforcing rib extending out of the side wall of the body is inserted into the first protrusion. This is beneficial for improving the overall strength of the guardrail base.
[0017] In one possible implementation of this utility model, the main body further includes a second through hole, which extends through the side wall of the main body along its width. The second through hole forms a lifting hole through which a steel wire rope passes. A lifting device is then used to grip the steel wire rope to transport the guardrail base to a designated location. This lifting process can be completed without the need for additional load-bearing components, thus improving the ease of transporting and installing the guardrail base.
[0018] In one possible implementation of this invention, the body further includes a groove with its opening facing the road surface; along the width of the body, both ends of the groove penetrate the side wall of the body. This allows water falling into the construction area to be discharged through the drainage ditch, which helps to reduce the impact of road flooding caused by thunderstorms on the project progress.

Detailed Implementation
[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted. The terms expressing position and direction described in the embodiments of this utility model are illustrative based on the accompanying drawings, but changes can be made as needed, and all such changes are included within the protection scope of this utility model. The accompanying drawings of the embodiments of this utility model are only for illustrating relative positional relationships and do not represent actual proportions.
[0028] It should be noted that specific details are set forth in the following description to facilitate understanding of this utility model. However, this utility model can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0029] With the continuous increase in national infrastructure investment, highways will also undergo lane reconstruction and expansion projects as well as road maintenance. However, due to the special nature of highways, lane reconstruction and expansion projects are usually carried out by closing only one lane or multiple lanes. Therefore, if vehicles traveling in other lanes accidentally enter the construction area due to overtaking, lane changing, or inclement weather, it will pose a significant safety threat to construction workers and equipment.
[0030] Currently, during the lane reconstruction and expansion of highways, the main method to improve safety in the construction area is to install guardrails around the perimeter. In existing technology, guardrails can be divided into two types: one type includes connected posts and beams, with the posts directly fixed to the road surface or connected to the road surface via other connecting structures; however, both methods damage the road surface. The other type includes a base and connected posts and beams, with the posts installed on the base, which is placed on the ground.
[0031] When setting up the base, it is usually necessary to add an additional counterweight inside the base and connect it to the base via connecting components to improve the stability of the base and ensure that the guardrail in the construction area meets the corresponding safety level requirements. However, this will increase the cost of the base and also increase the complexity of the base assembly process.
[0032] Therefore, how to improve the structural simplicity of the base and reduce its cost while meeting the safety requirements of the guardrail has become a problem that urgently needs to be solved by those skilled in the art.
[0033] In view of this, the guardrail base provided by this utility model, by setting multiple overlapping bodies, with the overlapping portion of two adjacent bodies used for connection with the post, effectively simplifies the structure of the guardrail base and reduces its cost while meeting safety level requirements. To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a more detailed description of this utility model in conjunction with the accompanying drawings and specific embodiments.
[0034] refer to Figure 1 , Figure 1 This is a partial structural diagram of the guardrail provided by this utility model. The guardrail includes beams ( Figure 1 (Not shown in the image) Column 01 and guardrail base. The guardrail base is used to install column 01, and a beam plate is installed between two adjacent columns 01. (Reference) Figure 2 , Figure 2 This is a schematic diagram of a guardrail base provided by this utility model. The guardrail base includes at least two adjacent bodies 1, along the axial direction of the column 01 (e.g., Figure 2 (As shown in the Z-axis direction), part of the body 1 is used to contact the road surface.
[0035] When specifically setting the body 1, the shape of the body 1 can be set according to actual needs. For example, the body 1 can be a rectangular block, and along such a line... Figure 2 As shown in the Z-axis direction, the bottom surface of the rectangular block is used to abut against the road surface to improve the stability of the guardrail base. It is worth noting that the edges of the rectangular block facing away from the road surface can be chamfered to reduce the risk of sharp edges causing injury to construction workers or vehicles.
[0036] In addition, such as Figure 3 As shown, one side wall of the body 1 is provided with a first protrusion 2, and the other side wall is provided with a second protrusion 3, and along the... Figure 3 As shown in the X-axis direction, the first protrusion 2 and the second protrusion 3 are opposite each other. Specifically, the first protrusion 2 protrudes from one side wall of the body 1 along the negative direction of the X-axis, while the second protrusion 3 protrudes from the other side wall of the body 1 along the positive direction of the X-axis.
[0037] When specifically setting the first protrusion 2, along the axial direction of the column 01 (e.g.) Figure 3 (As shown in the Z-axis direction), the first protrusion 2 includes a first surface 21 and a second surface 22 disposed opposite to each other, and the second surface 22 is used to abut against the road surface. Meanwhile, along the Z-axis direction, there is a gap 4 between the second protrusion 3 and the road surface, such as... Figure 2 As shown, the gap 4 is used to accommodate at least a portion of the first protrusion 2 of the adjacent body 1. The body 1, the first protrusion 2, and the second protrusion 3 can, for example, be an integral structure, which helps to improve the overall strength of the guardrail base, reduce costs, and facilitate manufacturing.
[0038] During the manufacturing process of Body 1, such as Figure 4 As shown, Figure 4 Figure 4 For display Figure 3 A sectional view along AA. A second reinforcing rib 11, such as a steel bar, can be provided inside the main body 1, and as shown in the figure. Figure 3 As shown, the length direction of the body 1 and the extension direction of the second reinforcing rib 11 are both along the X-axis, the width direction of the body 1 is along the Y-axis, and the height direction of the body 1 is along the Z-axis. In the specific arrangement of the second reinforcing rib 11, a portion of the second reinforcing rib 11 extends along the direction from the first protrusion 2 to the second protrusion 3 (e.g., Figure 4 The second reinforcing rib 11, which extends out of the side wall of the body 1 (in the positive direction of the X-axis shown), is inserted into the second protrusion 3, which helps to improve the overall strength of the guardrail base.
[0039] It is worth mentioning that, such as Figure 5 As shown, Figure 5 For display Figure 4 Along the cross-sectional view of BB, multiple second reinforcing ribs 11 can be provided inside the main body 1, and these multiple second reinforcing ribs 11 are spaced apart. For example, six second reinforcing ribs 11 can be provided inside the main body 1, of which three second reinforcing ribs 11 are spaced apart along the height direction of the main body 1, with an exemplary spacing of 6cm-12cm. The remaining three second reinforcing ribs 11 are spaced apart from the aforementioned three second reinforcing ribs along the Y-axis direction, and correspond one-to-one. This further enhances the overall strength of the guardrail base.
[0040] In addition, continue to refer to Figure 4 The main body 1 is also provided with a third reinforcing rib 12, such as a steel bar, and a portion of the third reinforcing rib 12 is along the direction from the second protrusion 3 to the first protrusion 2 (e.g., Figure 4 The third reinforcing rib 12, which extends out of the side wall of the body 1 (in the negative direction of the X-axis shown), is inserted into the first protrusion 2, which helps to further improve the overall strength of the guardrail base.
[0041] And such Figure 5As shown, multiple third reinforcing ribs 12 can also be provided inside the main body 1, and these multiple third reinforcing ribs 12 are spaced apart. For example, four third reinforcing ribs 12 can be provided inside the main body 1, wherein the four third reinforcing ribs 12 are spaced apart along the height direction of the main body 1, with an exemplary spacing of 6cm-12cm. The remaining two second reinforcing ribs 11 are spaced apart from the above two second reinforcing ribs 11 along the Y-axis direction, and correspond one-to-one. This can further improve the overall strength of the guardrail base.
[0042] It is understandable that the second reinforcing rib 11 and the third reinforcing rib 12 are arranged at intervals along the height direction of the body 1.
[0043] When the guardrail base is specifically installed around the construction area, in two adjacent bodies 1, the first protrusion 2 of one body 1 is used to insert into the gap 4 between the second protrusion 3 of the adjacent body 1 and the road surface. Meanwhile, as... Figure 1 As shown, the second protrusion 3 of one of the bodies 1 is connected to the first protrusion 2 of the adjacent body 1 through a column 01 to achieve a stable connection between the two adjacent bodies 1.
[0044] The guardrail base provided by this utility model has a first protrusion 2 and a second protrusion 3 that overlap between two adjacent bodies 1, and are stably connected by a column 01. Simultaneously, the second surface 22 of the first protrusion 2 and the bottom surface of the body 1 both abut against the road surface. This allows the assembled guardrail to meet safety requirements while effectively simplifying the structure of the guardrail base and reducing its cost.
[0045] It should be noted that this utility model does not limit the length of the main body 1. The exemplary length of the main body 1 is 2m, 4m, or 6m. However, in the specific design process, the length of the main body 1 can be adaptively adjusted by the spacing between two adjacent columns 01. Furthermore, during construction, multiple overlapping main bodies 1 can be set according to the length of the construction area. The setting angle between two adjacent main bodies 1 can be adjusted according to actual needs. For example, the angle between two adjacent main bodies 1 can be 90° or 180°, or other angles that meet actual setting requirements.
[0046] In a specific embodiment, such as Figure 3 As shown, along the axial direction of column 01 (e.g.) Figure 3 (As shown in the Z-axis direction), the second protrusion 3 includes a third surface 31 and a fourth surface 32 arranged opposite to each other. When specifically setting the guardrail base around the construction area, refer to [the relevant documentation / reference]. Figure 1 and Figure 2In two adjacent bodies 1, the second surface 22 of the first protrusion 2 of both bodies 1 abuts against the road surface, and the first surface 21 of the first protrusion 2 of one body 1 abuts against the fourth surface 32 of the second protrusion 3 of the adjacent body 1. This simplifies the structure of the guardrail base while effectively improving the connection stability of the two adjacent bodies 1. In addition, the third surface 31 of the second protrusion 3 can be coplanar with the top surface of the body 1, which helps to improve the processing convenience of the guardrail base and reduce production costs.
[0047] It is worth mentioning that you should continue to refer to Figure 1 and Figure 2 When the guardrail base is specifically installed around the construction area, in two adjacent bodies 1, the second protrusion 3 of body 1 is connected to the first protrusion 2 of the adjacent body 1 through a column 01, and along the direction of the first protrusion 2 away from the side wall of body 1, that is, the extension direction of the first protrusion 2 (e.g. Figure 2 (As shown in the X direction), the side wall of the first protrusion 2 of the first body 1 abuts against the side wall of the adjacent second body 1. This simplifies the structure of the guardrail base while effectively improving the connection stability of the two adjacent bodies 1.
[0048] Additionally, along the direction of the second protrusion 3 away from the side wall of the body 1, i.e., the extending direction of the second protrusion 3 (e.g. Figure 2 (in the X direction shown), the side wall of the second protrusion 3 of the second body 1 abuts against the side wall of the adjacent first body 1, which can effectively improve the connection stability of the two adjacent bodies 1 while simplifying the structure of the guardrail base.
[0049] In a specific embodiment, such as Figure 3 As shown, the first protrusion 2 also includes a first blind hole 23, while the second protrusion 3 includes a first through hole 33, and the axis of the first blind hole 23 and the axis of the second blind hole 14 are both parallel to the axis of the column 01.
[0050] When specifically placing the guardrail base around the construction area, such as Figure 2 As shown, in two adjacent bodies 1, the first blind hole 23 of the first protrusion 2 of one body 1 is coaxially arranged with the first through hole 33 of the second protrusion 3 of the adjacent body 1, and the coaxial first through hole 33 and first blind hole 23 are used to be sequentially inserted into the column 01. It can be understood that, as... Figure 1As shown, the column 01 is inserted into the first blind hole 23 through the first through hole 33, and the end of the column 01 abuts against the bottom of the first blind hole 23. The side wall of the column 01 abuts against the side walls of the first through hole 33 and the first blind hole 23. This simplifies the structure of the guardrail base and reduces its cost while meeting the safety requirements of the guardrail base. In addition, it also enables the recycling of the column 01 and the beam, effectively improving resource utilization and reducing pollution and carbon emissions.
[0051] like Figure 3 As shown, in an optional embodiment, the body 1 further includes a second blind hole 14, which is located between the first protrusion 2 and the second protrusion 3, and as... Figure 1 As shown, the second blind hole 14 is used to insert the post 01. It can be understood that the axis of the second blind hole 14 is parallel to the axis of the first blind hole 23, and the end of the post 01 abuts against the bottom of the second blind hole 14, while the side wall of the post 01 abuts against the side wall of the second blind hole 14. This design simplifies the structure of the guardrail base and reduces its cost while meeting the safety level requirements of the guardrail base (i.e., the protection capability requirements of Class A guardrails in the Highway Guardrail Safety Performance Evaluation Standard (JTG B05-01-2013)).
[0052] It is worth mentioning that, such as Figure 4 As shown, the main body 1 also includes a first reinforcing rib 13, which surrounds the second blind hole 14 along its circumference. It is understood that the first reinforcing rib 13 is annular, and the second blind hole 14 is located within the annulus. This helps to further improve the structural reliability of the guardrail base.
[0053] It should be noted that the guardrail base provided by this utility model can be precast reinforced concrete, and the body 1 can include multiple first reinforcing ribs 13. Along the Z-axis direction, the multiple first reinforcing ribs 13 are spaced apart, with an exemplary spacing of 12cm-14cm, which helps to further improve the structural reliability of the guardrail base.
[0054] In addition, the main body 1 can also be provided with multiple fourth reinforcing ribs 15, such as Figure 5 As shown, the fourth reinforcing rib 15 is ring-shaped, and multiple fourth reinforcing ribs 15 are spaced apart along the X-axis, with an exemplary spacing of 15cm-25cm. Furthermore, along the width direction of the body 1, the distance between the fourth reinforcing rib 15 and the surface of the body 1 is exemplary 4cm-5cm, while along the height direction of the body 1, the distance between the fourth reinforcing rib 15 and the surface of the body 1 is exemplary 5cm-6cm. Multiple second reinforcing ribs 11 and third reinforcing ribs 12 are also disposed within the ring. This is to further improve the structural reliability of the guardrail base.
[0055] It is worth mentioning that, along the X-axis direction, multiple fifth reinforcing ribs 24 can be spaced apart inside the first protrusion 2, with an exemplary spacing of 15cm-25cm. Furthermore, the fifth reinforcing ribs 24 are annular, and along the width direction of the body 1, the distance between the fifth reinforcing ribs 24 and the surface of the body 1 is exemplary 4cm-5cm, while along the height direction of the body 1, the distance between the fifth reinforcing ribs 24 and the surface of the body 1 is exemplary 3cm-4cm. Simultaneously, the fifth reinforcing ribs 24 are parallel to the fourth reinforcing ribs 15. And as... Figure 6 As shown, the third reinforcing rib 12, which is provided on the first protrusion 2, is located inside the ring.
[0056] Additionally, along the X-axis, multiple sixth reinforcing ribs 34 can be spaced apart inside the second protrusion 3, with an exemplary spacing of 12cm-25cm. Furthermore, the sixth reinforcing ribs 34 are annular, and along the width direction of the body 1, the distance between the sixth reinforcing ribs 34 and the surface of the body 1 is exemplaryly 4cm-6cm, and along the height direction of the body 1, the distance between the sixth reinforcing ribs 34 and the surface of the body 1 is exemplaryly 4cm-6cm. Simultaneously, the sixth reinforcing ribs 34 are parallel to the fourth reinforcing ribs 15. And as... Figure 7 As shown, the second reinforcing rib 11, located on the second protrusion 3, is inside the ring. Using the guardrail base provided by this utility model, when the length of the guardrail base is 4m, the width is 0.5m, and the height is 0.5m, the total weight of its reinforcing steel is 47kg, or 11.75kg / m, effectively increasing the reinforcement ratio and reducing the cost of the guardrail base while meeting the requirements of Class A protection capability.
[0057] It should be noted that the spacing between the second reinforcing rib 11 and the third reinforcing rib 12, which are located inside the annular reinforcing rib, and the annular reinforcing rib is, for example, 1cm-4cm. This is to reduce manufacturing costs while meeting the strength requirements of the guardrail body 1.
[0058] In addition, based on the strength requirements of the guardrail base, multiple reinforcing ribs can be additionally provided inside the first protrusion 2 along its length. These reinforcing ribs penetrate the aforementioned annular reinforcing rib and are spaced apart from and parallel to the other reinforcing ribs extending along the length. The spacing between these additional reinforcing ribs can be 5cm-7cm, in order to reduce manufacturing costs while meeting the strength requirements of the guardrail body 1.
[0059] In one alternative implementation, such as Figure 3As shown, the body 1 also includes a second through hole 16, which extends through the side wall of the body 1 along its width. The hole diameter is, for example, 3cm-3.5cm. During the installation of the guardrail base around the construction area, a steel wire rope can be passed through the second through hole 16, and then a hoisting device can be used to grab the steel wire rope to transport the guardrail base to the designated location. This hoisting can be completed without the need for additional load-bearing components, thus improving the convenience of transporting and installing the guardrail base.
[0060] In an alternative embodiment, the body 1 also includes a drainage channel 17, with the opening of the drainage channel 17 facing the road surface. Furthermore, both ends of the drainage channel 17 penetrate the sidewalls of the body 1 along its width. This allows water falling into the construction area to be discharged through the drainage channel 17, which helps to reduce the impact of road flooding caused by thunderstorms on the project's progress.
[0061] The shape of the drainage channel 17 can be set according to actual needs, for example, such as Figure 4 As shown, the drainage trough 17 has a trapezoidal cross-section along the length of the body 1. For example, the height of the trapezoidal cross-section is 78cm-82cm, the length of the bottom of the trapezoidal cross-section is 88cm-92cm, and the length of the opening of the trapezoidal cross-section is 98cm-102cm. This is to meet drainage requirements.
[0062] In summary, the guardrail base provided by this utility model has a first protrusion 2 and a second protrusion 3 that overlap between two adjacent bodies 1, and the two are stably connected by a column 01. Simultaneously, the second surface 22 of the first protrusion 2 and the bottom surface of the body 1 both abut against the road surface. This allows the assembled guardrail to meet safety requirements while effectively simplifying the structure of the guardrail base and reducing its cost.
[0063] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
