Problems solved by technology

The former has an increased demand for steel during construction and requires a large working space, while the latter has higher requirements for water depth at construction conditions, which can meet the docking requirements of gondolas, and the conditions for water navigation are limited. At the same time, the source of large floating cranes It is also one of the restrictive conditions, and the promotion of the process is not strong

Embodiment Construction

[0016] Referring to the accompanying drawings, its structure is to install a lifting system 2 on the main beam 1 of the fixed lifting bracket, the lifting system 2 is on the lifting system slideway 15, the lifting system 2 is connected to the lifting shoulder beam 3, and the beam section 4 to be lifted is placed on the beam transporting ship 5 Above, the front outrigger 6 is supported on the front outrigger base 7, the friction coefficient between the front outrigger base 7 and the slideway 8 is smaller than the friction coefficient between the guide beam and the erected beam section 12 and the slideway 8, and the rear support The leg column 10 is connected under the hinge seat 9 of the rear outrigger, and the rear outrigger column 10 is supported and fixed on the poured beam section 11. The assembly platform slideway 13 is on the assembly platform 14 to fix the gap between the main beams 1 of the lifting bracket. The horizontal connection structure 16 is a horizontal connectio...

Abstract

The invention discloses a fixed hoisting bracket device for pushing a steel box girder and a construction method thereof. The fixing crane bracket device comprises fixed hoisting bracket main beams, a hoisting system, a hanging carrying pole beam, a hanging beam section, a beam-transporting ship, a front supporting leg, a front supporting leg base, a slide rail, a back supporting leg hinged support, a back supporting leg upright column, a poured beam section, a guide beam, an erected beam section, an assembly platform slide rail, an assembly platform, a hoisting system slide rail and a horizontal connecting structure between the fixed hoisting bracket main beams. The construction method thereof comprises the following steps of: assembling and erecting the fixed hoisting bracket, arranging the hoisting system of the fixed hoisting bracket, hoisting the steel box girder, transforming the system of the steel box girder and assembling the steel box girder. The fixed hoisting bracket device has the advantages that: the steel box girder is stably, rapidly, continuously and uniformly hoisted in place; a pushing platform of the steel box girder or a beam top of the erected beam section is used as a supporting point of the front supporting leg of the fixed hoisting bracket to decrease the support height of the supporting leg to a bed and save the processing amount of steel structure; the bracket structure can bear force simply and clearly; the materials are convenient to acquire and are rapidly assembled; and the fixed hoisting bracket device is easy to popularize.

Description

technical field [0001] The invention relates to a fixed lifting support device and a construction method of a steel box girder for pushing construction, and belongs to the technical field of bridge construction. Background technique [0002] In the existing bridge construction, the steel box girder section is constructed by the jacking method. The weight of the steel box girder section is generally in the range of 100t-300t. The lifting operation of the steel box girder section usually requires the installation of large lifting devices and large Lift the platform, or use a large floating crane for lifting and installation operations. The former has an increased demand for steel during construction and requires a large working space, while the latter has higher requirements for water depth at construction conditions, which can meet the docking requirements of gondolas, and the conditions for water navigation are limited. At the same time, the source of large floating cranes ...
