Detailed description of the invention
Viaduct shrinkage joint steel girder erection levelling device, comprise support bar 1, fastening bolt 2, described support bar 1 is provided with several, through hole 11 is provided with in the middle part of described support bar 1, described fastening bolt 2 is corresponding one by one with support bar 1, be connected with support bar 1 by through hole 11, the head upright of described fastening bolt 2 is placed downwards.
The length of described fastening bolt 2 is greater than thickness and the width of described support bar 1.
Described support bar 1 is straight, smooth surface.
Described support bar 1 two ends are provided with and support turning 12.
Using method of the present utility model is, first fastening bolt 2 is loosened, distance between the head of fastening bolt 2 and support bar 1 is extended, because shrinkage joint 3 is " L " shape, and the shrinkage joint 3 of installing in bridge 4 is symmetrical installation, so, support bar 1 is disposed across on the road surface of bridge 4, by fastening bolt 2 head down from the side at shrinkage joint 3, penetrate in shrinkage joint 3, tighten the fastening bolt 2 on support bar 1, the upper surface at shrinkage joint 3 is made to be adjacent to the soffit of support bar 1, because support bar 1 is disposed across on the road surface of bridge 4, when the upper surface at shrinkage joint 3 is adjacent to the soffit of support bar 1, also be in same plane with the road surface of bridge 4 simultaneously.
Described fastening bolt 2 both sides are provided with back-pressure centering bolt 5, by the acting in opposition to shrinkage joint 3, carry out leveling process to shrinkage joint 3.
The utility model also comprises hydraulic pressure and heightens bar 6, described hydraulic pressure is heightened bar 6 and is comprised flower basket bolt 61, crossbeam 62 and jack 63, described crossbeam 62 is fixed on the top of described jack 63, described flower basket bolt 61 is arranged on the two ends of described crossbeam 62, during use, by flower basket bolt 61 being fixed on the ground of side, shrinkage joint 3, jack 63 is placed in top, shrinkage joint, jack 63 is adjusted, described hydraulic pressure heightens the side that bar 6 is placed on described support bar 1, coordinate support bar 1, calibrated altitude is adjusted to shrinkage joint 3.
Above-described embodiment, just in order to technical conceive of the present utility model and feature are described, its objective is and is one of ordinary skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.The change of every equivalence done by the essence of the utility model content or modification, all should be encompassed in protection domain of the present utility model.
