Abstract

The invention provides a shaping clamp for repairing of the surfaces of concrete guard bars and a repairing method of the shaping clamp, and relates to the field of bridge construction. The shaping clamp comprises a rectangular supporting plate, a stopping lever, a clamping piece and a jacking piece, wherein the stopping lever is connected to the edge of the outer side of the supporting plate; theclamping piece is connected to the bottom surface of the inner side of the supporting plate; and the jacking piece is connected to the top surface of the outer side of the supporting plate. The clamping piece comprises a clamping plate, nuts and jackscrews, the clamping plate is perpendicularly connected to the edge of the inner side of the supporting plate, the nuts and the jackscrews are horizontally welded to the bottom of the top plate at intervals, screw holes are horizontally formed in the bottom of the clamping plate at intervals and correspond to welding positions of the nuts, and thejackscrews successively penetrate through the nuts and the screw holes. The problem that templates need to be erected during repairing of the surfaces of existing concrete guard bars, construction isheavy and complicated, and construction of urban roads with narrow space and operation at night are not facilitated are solved, and meanwhile, the problem that the straightness and the flatness of the surfaces of anti-collision guard bars are low is solved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a shaping fixture used for repairing the surface of a concrete guardrail and a repairing method thereof. Background technique [0002] With the rapid development of bridge construction in my country, the construction and maintenance of bridges in my country has gradually shifted from "mainly focusing on construction" to "emphasizing both construction and maintenance", and the bridge anti-collision guardrail is an important part of the bridge superstructure. In the project, the appearance quality and structural safety of the anti-collision guardrail are an important part of bridge maintenance. The main purpose of the anti-collision guardrail is to prevent out-of-control vehicles from going out of the bridge, and has the function of preventing vehicles from breaking through, going under, and over the bridge, and beautifying the bridge building. However, with the operation of the ...
