The positioning steel plate mounting frame is a rectangular frame structure welded by section steel. Both long sides of the positioning steel plate mounting frame are angle steel parts. Strip - shaped grooves are arranged at both ends of both long sides of the positioning steel plate mounting frame. The first positioning steel plate and the second positioning steel plate are respectively connected to both ends of the positioning steel plate mounting frame through bolts in cooperation with the strip - shaped grooves arranged on both long sides of the positioning steel plate mounting frame. Bolt holes corresponding to the embedded bolts of the steel guardrail are arranged on both the first positioning steel plate and the second positioning steel plate. An adjusting nut is fixed at each of the four corner ends of the positioning steel plate mounting frame. The axis of the adjusting nut is perpendicular to the mounting surface of the first positioning steel plate and the second positioning steel plate. The four adjusting screws are respectively thread - connected to the four adjusting nuts.
[0005] In the present utility model, the distance between the first positioning steel plate and the second positioning steel plate can be adjusted according to the designed distance between two steel guardrail embedded parts. After the distance between the two positioning steel plates is adjusted, they can be fixed on the positioning steel plate mounting frame through bolts. When the present utility model is in use, the positioning steel plate mounting frame is arranged at the designed position of the steel guardrail embedded bolts. The four adjusting screws respectively support on the concrete ground on both sides of the embedded part mounting groove. The steel guardrail embedded bolts to be embedded are all passed through the bolt holes on the first positioning steel plate and the second positioning steel plate. By adjusting the plane position of the positioning steel plate mounting frame, the horizontal position of the embedded bolts can be accurately positioned. By adjusting the four adjusting screws at the four corners of the positioning steel plate mounting frame, the verticality of the embedded bolts can be adjusted. After adjustment, the embedded bolts are welded and fixed together with the structural steel bars in the embedded part mounting groove. After the embedded bolts are fixed, the device can be removed.
[0006] Further, both long sides of the positioning steel plate mounting frame are angle steel parts. The use of angle steel parts for both long sides of the positioning steel plate mounting frame can not only ensure the structural strength of the positioning steel plate mounting frame and prevent it from being deformed easily, but also facilitate the installation and fixation of the first positioning steel plate and the second positioning steel plate.
[0007] Further, to ensure that the adjusting screws can support on the concrete ground on both sides of the embedded part mounting groove, the width of the positioning steel plate mounting frame is 350 mm - 500 mm.
[0008] The beneficial effects of the present utility model are as follows: The structure of the present utility model is simple, and the installation and operation are convenient. The guardrail embedded bolts only need to be fixed on the two positioning steel plates in advance. By adjusting the plane position of the positioning steel plate mounting frame, the accurate positioning of the horizontal position of the embedded bolts can be realized. By adjusting the four screws at the four corners of the positioning steel plate mounting frame, the accurate vertical positioning of the embedded bolts can be achieved. It can not only greatly improve the installation accuracy of the embedded bolts, but also greatly reduce the time for adjusting and positioning the embedded bolts, with high construction efficiency and accelerated construction progress.
