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 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 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.
Description
[technical field]
The present invention relates to solve a kind of job practices that is used for the large-scale steel bridge beam of Fast Installation under the big construction environment of Traffic Flow of Major Road of City amount, particularly relate to a kind of job practices of using the big shaped steel case of simple and easy brief summary member Fast Installation beam.
[background technology]
At present; The mounting method of large-scale steel bridge beam generally adopts artificial commander, and manpower draws the artificial method of adjustment of establishing cable wind rope, and the steel bridge beam that needs are installed is set up on predetermined bridge pier or support; This method construction precision is low; Operating speed is slow, and steel case beam very easily misplaces in lifting case beam process, adjusts long with regard to bit time.If under the big environment of Traffic Flow of Major Road of City amount; For obstruction not, require operating efficiency high especially, construction finishes as early as possible; So existing conventional construction method can not satisfy the demands, a kind of method that large-scale bridge girder steel is installed fast and accurately of market demand.
[summary of the invention]
The objective of the invention is to above technical deficiency; A kind of job practices that is used at the large-scale steel bridge beam of major urban arterial highway Fast Installation is provided; The present invention is directed to the defective of existing conventional construction method; Can carry out installing and locating to large-scale steel bridge beam fast, accurately, improve operating efficiency, implement convenient and practical.
Technical scheme of the present invention is described below: a kind of job practices that is used at the large-scale steel bridge beam of major urban arterial highway Fast Installation is characterized in that it comprises following construction sequence:
1), in falsework one side of waiting to set up the steel bridge beam 2-3 spare location i iron or channel-section steel are installed, effect is a 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 location i iron or channel-section steel are installed, effect is the upper and lower displacement of control steel case beam in vertical direction, 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; The artificial tension of cable wind rope, steel case beam leans against on described location i iron or the channel-section steel, and effect is a 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 location i iron or the channel-section steel, effect is the upper and lower displacement of control steel case beam in vertical direction, accomplishes the installation of steel bridge beam at last.
According to above-mentioned technical scheme, its characteristic is that also the 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 that [20-[24.
According to above-mentioned technical scheme, its characteristic is that also the i iron model is I20-I24 to control steel case beam in the location of the upper and lower displacement of vertical direction, and perhaps the channel-section steel model is that [20-[24.
According to above-mentioned technical scheme, its characteristic also is, control steel case beam in the length of the location of the upper and lower displacement of vertical direction i iron or channel-section steel greater than 30 millimeters-50 millimeters of jack height.
According to the present invention of above-mentioned technical characterstic, installation accuracy is high, and speed is fast, and the workman is easy to control in hoisting process, can practice thrift artificial and material and mechanical one-shift, not limited by the place, and security performance is high.
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 is provided with 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]
Like Fig. 1, shown in 2, a kind of job practices that is used at the large-scale steel bridge beam of major urban arterial highway Fast Installation is characterized in that, it comprises following construction sequence:
1), in falsework one side of waiting to set up the steel bridge beam 2-3 spare location i iron or channel-section steel are installed, effect is a 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 location i iron or channel-section steel are installed, effect is the upper and lower displacement of control steel case beam in vertical direction, 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; The artificial tension of cable wind rope, steel case beam leans against on described location i iron or the channel-section steel, and effect is a 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 location i iron or the channel-section steel, effect is the upper and lower displacement of control steel case beam in vertical direction, accomplishes the installation of steel bridge beam at last.
