Description

Technical Field

[0001] The utility model belongs to the technical field of highway guardrail protection, specifically a corrugated beam barrier block and a wing wall and corrugated beam guardrail overlap structure formed therefrom, which is used for overlapping a concrete guardrail with a corrugated beam guardrail of SB or above grade, and making a transition connection through a friction beam. Background Art

[0002] According to the requirements of the "Design Rules for Highway Traffic Safety Facilities" (JTG / T D81-2017), when the guardrail of a highway bridge with a design speed greater than 60km / h is different from the roadbed guardrail, a transition section design should be carried out. The transition section adopts the method of setting end wing walls or overlapping the semi-rigid guardrail on the rigid guardrail. However, the specification only provides that the form of the friction beam anti-obstruction block at the bottom of the transition section of the A-level corrugated guardrail of the roadbed section and the bridge guardrail can be processed with reference to the A-level corrugated beam guardrail anti-obstruction block, and does not describe the form of the friction beam anti-obstruction block at the bottom of the transition section of the SB-level and above corrugated guardrail and the bridge guardrail. At present, during construction, for the friction beam anti-obstruction blocks at the bottom of the transition section of the SB-level and above corrugated guardrail and the bridge guardrail, the construction units generally still process them according to the A-level corrugated beam guardrail anti-obstruction blocks. For example, the patent document with application number CN202120978347.9 discloses a non-welded three-wave anti-obstruction block, and the side of the anti-obstruction block away from the column is fixedly connected to an anti-obstruction block side ear, the side of the anti-obstruction block side ear is provided with a side ear bolt hole, and the interior of the anti-obstruction block is fixedly connected to an anti-obstruction block reinforcement strip.

[0003] Since the A-level corrugated beam guardrail barrier blocks are only suitable for round guardrail steel pipe columns, and the SB-level and above corrugated beam guardrails are square guardrail steel pipe columns, the SB-level and above corrugated guardrails do not match the friction beams and columns when connected, causing the friction beams to be located inside the third-level corrugated guardrail, affecting the guardrail's anti-collision effect and aesthetics. Utility Model Content

[0004] As described in the background technology, in the prior art, the SB-level and above corrugated guardrails are not matched with the friction beams and columns when connected, so that the friction beams are located inside the third-level corrugated guardrails, which has a technical problem of affecting the anti-collision effect and aesthetics of the guardrails. In response to this technical problem, the utility model proposes a corrugated beam barrier block and a wing wall formed by the corrugated beam guardrail overlap structure.

[0005] The corrugated beam barrier block of the utility model is arranged between the curb and the three-level corrugated guardrail, and is used to connect the column and the friction beam. The column needs to extend upward to connect with the three-level corrugated guardrail. Therefore, the column needs to pass through the body of the corrugated beam barrier block. In order to match the connection between the column and the friction beam, the utility model arranges a column hole on the body of the corrugated beam barrier block, so that the column passes through the body of the corrugated beam barrier block and extends to above the friction beam, so that the body of the corrugated beam barrier block matches the column.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] The utility model discloses a corrugated beam anti-blocking block, comprising a corrugated beam anti-blocking block body, wherein the corrugated beam anti-blocking block body is used to connect a column and a friction beam;

[0008] The body of the corrugated beam anti-block includes a middle connecting part and a side connecting part connected to the middle connecting part, wherein the side connecting part is connected to the friction beam; a column hole is provided on the middle connecting part, and the column passes through the column hole and is fixedly connected to the middle connecting part.

[0009] It is further defined that the bottom end surface of the middle connecting portion and the bottom end surface of the side connecting portion are in the same horizontal plane.

[0010] It is further defined that side connection parts are provided on both sides of the middle connection part, and the side connection parts on both sides of the middle connection part are connected to the friction beam.

[0011] It is further defined that the side connection parts on both sides of the middle connection part are connected to the friction beam through connecting pieces.

[0012] It is further defined that the middle connection portion is provided with a first middle connection hole and a second middle connection hole connected to the column; the side connection portion is provided with a side connection hole for connecting to the friction beam, and the connection member passes through the side connection hole.

[0013] It is further defined that there is one side connection hole, which is arranged at an upper middle position of the side connection part.

[0014] The utility model discloses a wing wall and corrugated beam guardrail overlap structure, comprising a concrete wing wall, a three-level corrugated beam guardrail and the above-mentioned corrugated beam barrier block, wherein the three-level corrugated beam guardrail is arranged above the friction beam, and the column extends through the column hole to the position of the three-level corrugated beam guardrail and is connected to the three-level corrugated beam guardrail; the three-level corrugated beam guardrail and the friction beam are both connected to the concrete wing wall.

[0015] It is further defined that the third-level wave guardrail is arranged in parallel with the friction beam along the length direction of the friction beam.

[0016] It is further defined that the corrugated beam anti-block body and the friction beam are both arranged above the curb.

[0017] It is further defined that there are multiple columns arranged in parallel, each column corresponds to a corrugated beam anti-obstruction block body, each column is connected to the friction beam through the corresponding corrugated beam anti-obstruction block body, and each column passes through the column hole on the middle connecting part and is connected to the third-level corrugated guardrail.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The corrugated beam barrier block of the utility model is arranged between the curb and the third-level corrugated guardrail, and is used to connect the column and the friction beam. The column needs to extend upward to connect with the third-level corrugated guardrail. The friction beam is arranged between the third-level corrugated guardrail and the concrete wing wall, and plays the role of transition connection between the third-level corrugated guardrail and the concrete wing wall. Since the friction beam is close to the curb and the column needs to penetrate the corrugated beam barrier block when connecting with the third-level corrugated guardrail, the existing barrier block cannot be applied to the connection between the column and the friction beam. In order to match the connection between the column and the friction beam, the utility model sets a column hole on the body of the corrugated beam barrier block, so that the column penetrates the body of the corrugated beam barrier block and extends to the top of the friction beam to connect with the third-level corrugated guardrail, so that the body of the corrugated beam barrier block matches when connected with the column and the friction beam, and can be applied to the connection between the friction beam and the column, thereby improving the anti-collision effect and aesthetics of the third-level corrugated guardrail.

[0020] 2. The bottom end face of the middle connection part of the utility model is in the same horizontal plane as the bottom end face of the side connection part. Because the friction beam is set close to the curbstone and relatively close to the roadbed, the bottom end face of the side connection part of the existing anti-blocking block extends below the bottom end face of the middle connection part and exceeds the bottom end face of the middle connection part by a large amount, which is not suitable for the connection between the side connection part and the friction beam. Therefore, the utility model sets the bottom end face of the middle connection part and the bottom end face of the side connection part in the same horizontal plane, so that the side connection part can be better connected to the friction beam close to the roadbed.

[0021] 3. The utility model provides a lap joint structure of a wing wall and a corrugated beam guardrail, in which a friction beam is arranged at the connection between the concrete wing wall and the third-level corrugated beam guardrail, and the friction beam plays the role of transition connection; the connection between the concrete wing wall and the third-level corrugated beam guardrail is made more firm and more in line with the requirements of the specification.
