Embodiment Construction

[0027] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0028] A construction method for laterally erecting steel plate composite beams, the central positioning of the bottom opening and the top opening of the steel pipe column includes the following steps:

[0029] A. First set up the temporary bracket for the beam body erection, set up bolt holes and hoisting holes on the bracket beam 1, install the chute 3 on the slideway beam 2, and the limit chute 3 is two limit angle steels, and the limit slide The groove 3 is fixed on the slideway beam 2 with bolts, then the slideway beam 2 is hoisted, the slideway beam 2 is installed on the support beam 1, and the slideway beam 2 and the support beam 1 are welded firmly;

[0030] B. Put the slider 4 in the limit chute 3, and fix the adjustable screw strut 8 with a steel pin on the slider 4, and the adjustable screw strut 8 on both side...

Abstract

The invention discloses a construction method for transversely moving and erecting a steel plate composite beam. The method comprises the following steps of: firstly, erecting a temporary bracket forerecting a beam body, installing a slideway beam on a bracket cross beam, and installing a sliding groove in the slideway beam; arranging a sliding block in the sliding groove, fixing an adjustable screw rod to the sliding block through a steel pin, enabling the top of the adjustable screw rod to abut against the steel plate composite beam, and using a continuous jack fixed to the slideway beam topull a steel strand connected with the sliding block to achieve transverse movement of the composite beam; and after the transverse movement in place, finely adjusting the beam section through a three-way jack arranged on the bracket cross beam until the precision requirement is met, and continuously finishing the subsequent connection and installation of the steel plate composite beam. The construction method is safe, reliable and easy to install. The difficulties that in urban bridge construction, normal hoisting cannot be achieved due to the influence of high-voltage lines and the clearance influence of an existing viaduct are fully considered, and the construction method using the continuous jack and the steel strand to pull the sliding block to transversely move the composite beam isused to solve the problem that the clearance of hoisting operation is not enough.

Description

technical field [0001] The invention relates to the field of municipal bridge construction, in particular to a construction method for laterally erecting steel plate composite girders for solving the construction site where the existing high-voltage line, the existing viaduct, etc. are limited in the air and cannot be normally lifted and installed vertically. Background technique [0002] With the increasing scale of urban construction in our country, the construction of urban viaducts is also increasing day by day, and the contradiction between urban construction and urban planning has become more and more obvious. As a result, in the process of bridge construction in many locations, there are often problems of insufficient clearance under high-voltage lines along the line. Phenomena, there is a great potential safety hazard for bridge construction; or the new bridge needs to cross the existing urban viaduct or overpass bridge, and the problem of insufficient hoisting cleara...
