Abstract
The invention discloses a construction method for rapidly installing a large steel bridge on an urban arterial road, which is characterized by comprising the following technical steps of: installing two to three horizontal positioning joist steels or U-steels at one side of a temporary bracket of a steel bridge to be erected, wherein the positioning joist steels or U-steels have the effect of controlling the right-and-left displacement of a steel box girder in the horizontal direction; installing two vertical positioning joist steels or U-steels at both ends of a temporary bracket of a pier of the steel bridge to be erected, wherein the positioning joist steels or U-steels have the effect of controlling the vertical displacement of the steel box girder in the vertical direction; and welding a positioning steel plate at the bottom of the steel box girder to be erected so as to ensure the horizontal displacement of the steel box girder in the horizontal direction. The construction method has the advantages of being high in installation precision, speed and safety performance, being free from the limitation of fields, being easy for workers to control in the hoisting process and saving labor, materials and mechanical team.

Technical scheme of the present invention is as described below: a kind ofly it is characterized in that for the job practices at the large-scale steel bridge beam of major urban arterial highway Fast Installation it comprises following construction sequence:
1), in falsework one side of waiting to set up the steel bridge beam 2-3 spare horizontal location i iron or channel-section steel are installed, effect is control steel case beam left and right displacement in the horizontal direction;
2), at the falsework two ends of waiting to set up the steel bridge beam two vertically location i iron or channel-section steels are installed, effect is the upper and lower displacement in the vertical direction of control steel case beam, with the jack fine setting, reaches steel case beam design elevation at last;
3), in welding fixing steel plate in steel case beam bottom to be set up, the front and back displacement in the horizontal direction of assurance steel case beam;
4), when steel case beam is installed, the crane steel case beam of slinging, steel case beam both sides pull-up cable wind rope, steel case beam is during near on-station position, cable wind rope is manually strained, and steel case beam leans against on described horizontal location i iron or the channel-section steel, and effect is control steel case beam left and right displacement in the horizontal direction;
5), steel case beam is during near on-station position, steel case beam is placed on vertical location i iron or the channel-section steel, effect is the upper and lower displacement in the vertical direction of control steel case beam, finishes the installation of steel bridge beam at last.
Technical scheme according to above-mentioned is further characterized in that, the horizontal location i iron model of control steel case beam left and right displacement in the horizontal direction is I20-I24, and perhaps the channel-section steel model is [20-[24.
Technical scheme according to above-mentioned is further characterized in that, the vertical location i iron model of control steel case beam upper and lower displacement in the vertical direction is I20-I24, and perhaps the channel-section steel model is [20-[24.
Technical scheme according to above-mentioned is further characterized in that, the vertical location i iron of control steel case beam upper and lower displacement in the vertical direction or the length of channel-section steel are greater than 30 millimeters-50 millimeters of jack height.
According to the present invention of above-mentioned technical characterstic, the installation accuracy height, speed is fast, and the workman is easy to control in hoisting process, can save artificial and material and mechanical one-shift, not limited by the place, the security performance height.
Below in conjunction with accompanying drawing and implementation process this method is described further.
[description of drawings]
Accompanying drawing 1 is that steel case beam of the present invention arranges level and the structural representation of vertically locating i iron.
Accompanying drawing 2 is structural representations of steel case beam of the present invention bottom welding fixing steel plate.
Steel bridge beam in the drawings, 1; 2, bridge pier or support; 3, vertically locate i iron or channel-section steel; 4, jack; 5, horizontal location i iron or channel-section steel; 6, fixing steel plate.
[specific embodiment]
As shown in Figure 1, 2, a kind ofly it is characterized in that for the job practices at the large-scale steel bridge beam of major urban arterial highway Fast Installation it comprises following construction sequence:
1), in falsework one side of waiting to set up the steel bridge beam 2-3 spare horizontal location i iron or channel-section steel are installed, effect is control steel case beam left and right displacement in the horizontal direction;
2), at the falsework two ends of waiting to set up the steel bridge beam vertical two location i iron or channel-section steel are installed, effect is the upper and lower displacement in the vertical direction of control steel case beam, with the jack fine setting, reaches steel case beam design elevation at last;
3), in welding fixing steel plate in steel case beam bottom to be set up, the front and back displacement in the horizontal direction of assurance steel case beam;
4), when steel case beam is installed, the crane steel case beam of slinging, steel case beam both sides pull-up cable wind rope, steel case beam is during near on-station position, cable wind rope is manually strained, and steel case beam leans against on described horizontal location i iron or the channel-section steel, and effect is control steel case beam left and right displacement in the horizontal direction;
5), steel case beam is during near on-station position, steel case beam is placed on vertical location i iron or the channel-section steel, effect is the upper and lower displacement in the vertical direction of control steel case beam, finishes the installation of steel bridge beam at last.
