Abstract
The invention discloses a construction method of railway steel truss girder T-shaped stiffening rib orthotropic slab bridge deck, aiming to improve construction efficiency of the bridge deck and obtain more ensured construction quality. The method comprises the following steps: 1. welding the T-shaped stiffening rib (11), a longeron (12) on a bridge deck steel plate (10) to form bridge deck steel plate sections; 2. inserting two beams (20) into the bridge deck steel plate sections and welding the beams with the steel plate sections to form an integral beam section; 3. hoisting the integral beam section to a preset position, bolting the beams (20) and lower chord of the steel truss girder to finish installation of the integral beam section. The invention has the beneficial effect that as assembly of the integral beam section is completed in site, assembly and welding quality can be more easily ensured; in addition, the integral beam section is hoisted to the steel truss girder to assemble bridge deck plates, so that construction efficiency of the bridge deck can be obviously improved.
Description
Technical field
The present invention relates to railroad bridge, particularly a kind of job practices of steel truss girder T type stiffening rib orthotropic plate bridge floor.
Background technology
Highway and rail iron trusses orthotropic plate mostly are U type stiffening rib, its job practices is fairly simple, lay crossbeam and longeron earlier and then lay orthotropic plate, because U type stiffening rib is up big and down small, thereby can directly lay, but U type stiffening rib can only single-sided welding, and is very strict to welding process requirement, and fatigue failure appears in welding position easily.T type stiffening rib can two-sidedly weld, and has solved the problem of the aforementioned existence of U type stiffening rib, but there is bigger difficulty of construction in T type stiffening rib.
At present, the job practices that T type stiffening rib orthotropic plate bridge floor adopts is undertaken by following step: ground 1. on the scene processes each bridge floor steel plate sections, and soon T type stiffening rib, longeron are welded on the bridge floor steel plate; 2. two crossbeams lifting of first sections is put in place and with the lower chord bolt of steel truss girder, penetrate first bridge floor steel plate sections again and weld with crossbeam; 3. two crossbeams lifting of next sections is put in place and with the lower chord bolt of steel truss girder, penetrate next bridge floor steel plate sections again.Because construction the time can only aloft be constructed on one section one section ground, and require great effort very much when bridge floor steel plate sections penetrated crossbeam, there is the low deficiency of efficiency of construction in this method, and construction quality also is not easy to be guaranteed.
Summary of the invention
Technical problem to be solved by this invention provides a kind of job practices of rail iron trusses T type stiffening rib orthotropic plate bridge floor, can improve the efficiency of construction of bridge floor significantly, and makes that construction quality is easier to be guaranteed.
The technical solution adopted for the present invention to solve the technical problems is: the job practices of rail iron trusses T type stiffening rib orthotropic plate bridge floor of the present invention, comprise the steps: 1. T type stiffening rib, longeron to be welded on the bridge floor steel plate, form bridge floor steel plate sections; Two crossbeams are penetrated bridge floor steel plate sections and welding with it respectively, form the unjointed beam section; 3. the lifting of unjointed beam section puts in place, with the lower chord bolt of crossbeam and steel truss girder, finishes the installation of a unjointed beam section.
The invention has the beneficial effects as follows, finish the assembling of unjointed beam section in the venue, assembling, welding quality is easier is guaranteed; The unjointed beam section lifted assemble bridge deck on the steel truss girder, can improve the efficiency of construction of bridge floor significantly.

Component shown in the figure, toponym and pairing mark: bridge floor steel plate 10, T type stiffening rib 11, longeron 12, crossbeam 20, shear connector 30.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
The job practices of rail iron trusses T type stiffening rib orthotropic plate bridge floor of the present invention comprises the steps:
1. with reference to Fig. 1, T type stiffening rib 11, longeron 12 are welded on the bridge floor steel plate 10, form bridge floor steel plate sections;
2. with reference to Fig. 2 and Fig. 3, two crossbeams 20 are penetrated bridge floor steel plate sections and welding with it, form the unjointed beam section; With reference to Fig. 2,, can alleviate difficulty of construction because two crossbeams 20 can be respectively penetrated from vertical end of bridge floor steel plate sections.
3. the lifting of unjointed beam section puts in place, with the lower chord bolt of crossbeam 20 with the bridge main truss, finishes the installation of a unjointed beam section.
Be further to reduce the construction operation amount on the bridge main truss, and become in the lifting operation of unjointed beam section, with reference to Fig. 4, described step 2. after, can be with the upset of unjointed beam section, welding has the shear connector 30 of suspension ring structure on bridge floor steel plate 10.With reference to Fig. 5, this novel shear connector 30 is welded by the steel plate of two square crossings, on its 4 facades, be provided with slotted eye, except that the effect that can be subjected to bidirectional stress make steel work and reinforced concrete structure is more effective combine, slotted eye also constitute can for wirerope wear around the suspension ring structure, therefore also can make things convenient for the lifting operation of unjointed beam section.
Claims (2)
1. the job practices of rail iron trusses T type stiffening rib orthotropic plate bridge floor comprises the steps: 1. T type stiffening rib (11), longeron (12) to be welded on the bridge floor steel plate (10), forms bridge floor steel plate sections; 2. two crossbeams (20) are penetrated bridge floor steel plate sections and welding with it respectively, form the unjointed beam section; 3. the lifting of unjointed beam section puts in place, with the lower chord bolt of crossbeam (20) with steel truss girder, finishes the installation of a unjointed beam section.
2. the job practices of rail iron trusses T type stiffening rib orthotropic plate bridge floor according to claim 1 is characterized in that: described step 2. after, the upset of unjointed beam section is gone up the shear connector (30) that welding has the suspension ring structure at bridge floor steel plate (10).
