[0002] In the construction of expressways, the installation of the flange plate of the guardrail base is widely used in construction. Its function is to connect the guardrail column and the concrete of the guardrail base to ensure the accurate position of the subsequent guardrail column. At present, manual positioning is used in the construction process, but there are defects such as inaccurate positioning, inconvenient movement, insufficient flatness, and long time consumption. Chinese Patent CN106702907A discloses a construction method for an adjustable flange plate of a bridge guardrail base, which has many construction steps, and the plane position and elevation of the flange plate cannot be accurately controlled; at the same time, due to the existence of embedded steel bars in the guardrail base, this construction method affects the operation, has low efficiency; and new steel bars need to be added in the middle of the original embedded steel bars, which greatly increases the consumption of steel bar raw materials and cannot guarantee the integrity of the design; there are too many internal steel bars after construction, resulting in difficulties in subsequent steel tendon threading. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art, and provide a quick and precise leveling device for the flange plate of the highway guardrail base, which realizes the quick and precise leveling of the flange plate of the highway guardrail base by a simple and easy-to-implement structure, ensures the construction quality and precision, and speeds up the construction progress.

[0004] The technical solution adopted by the utility model to achieve the above purpose is: a quick and precise leveling device for the flange plate of the highway guardrail base, characterized in that: it includes a positioning mold, a height adjustment bolt, and a positioning piece. The positioning mold is a rectangular frame structure, and openings are provided at both ends of one long side. A height adjustment bolt for adjusting the overall height of the device is connected in the opening. At least two positioning pieces for fixing the flange plate are connected in the groove in the middle of the positioning mold. The positioning pieces are rectangular sheets, and the positioning pieces and the flange plate are connected by U-shaped anchor bolts.

[0005] The inner width of the frame of the positioning mold is 400mm, and the outer frame length is 440mm.

[0006] The length of the height adjustment bolt is 220mm, and it is connected to the positioning mold through the screw thread nut of the height adjustment bolt.

[0007] The anchor bolt and the positioning piece are connected by a nut.

[0008] A rapid precision leveling device for the flange plate of the highway guardrail base proposed by the utility model. When installing the flange plate, place the device at the guardrail base. According to the setting-out position, position the positioning template, adjust the height adjustment bolts so that the lower edge of the positioning die is at the designed elevation. After connecting the flange plate with the positioning piece, place the positioning piece on the positioning die and connect the flange plate with the embedded bars of the guardrail base. The utility model quickly positions and supports through the positioning die, quickly adjusts the elevation of the positioning die by using the height adjustment bolts, and quickly adjusts the flange plate to the designed position by using the positioning piece, with the characteristics of fast positioning, accuracy, convenient movement, and one-time forming. Its construction steps are simple, and the plane position and elevation of the flange plate can be accurately controlled; at the same time, this construction method is not affected by the existence of embedded bars in the guardrail base, greatly improving the construction efficiency, significantly reducing the consumption of steel raw materials, and ensuring the integrity of the design.

DETAILED DESCRIPTION OF THE EMBODIMENTS Embodiment

[0013] Such as Figures 1 - 3 A rapid precision leveling device for the flange plate of the highway guardrail base shown, including a positioning die 1, a height adjustment bolt 3, and a positioning piece 2. The positioning die 1 is a rectangular frame structure, with openings at both ends on one side of its long side. The height adjustment bolts 3 for adjusting the overall height of the device are connected in the openings. At least two positioning pieces 2 for fixing the flange plate 5 are connected in the groove in the middle of the positioning die 1, which are rectangular pieces. The positioning piece 2 and the flange plate 5 are connected by a U-shaped anchor bolt 6.
