Technical field
The utility model relates to bracing or strutting arrangement, particularly relates to a kind of bridge transition cross T-shaped side bar the rigid support device is installed.
Background technology
In that large bridge is cast-in-place when striding with prefabricated mid-span, because the proper supporting device is not provided, generally be that precast beam is installed earlier, pour into a mould cast-in-situ box girder then, but prestressed reinforcement can only carry out tensioned at one end in this restriction cast-in-situ box girder, surpasses the standard allowable error with two ends simultaneous tension data differences, has a strong impact on case beam stress system, change over the force structure behind the bridge, reduce bridge application life.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of when the bridge formation machine is installed side bar, do not allow box beam flange plate be subjected to vertical active force and the impaired frame sedan-chair pusher side that causes turns over, but bridge formation machine track directly props up a kind of load-bearing rigid support device of pad on pre-embedded steel slab, and this device is installed the rigid support device for bridge transition cross T-shaped side bar.
The technical scheme that its technical problem that solves the utility model adopts is: comprise pre-embedded steel slab, supporting steel pipe and foundation means, wherein, foundation means is made up of concrete pillar, cap, pedestal steel plate, and cap rests on the concrete pillar, and the pedestal steel plate lies in the cap end; Described supporting steel pipe, its lower end are welded on the pedestal steel plate, and its upper end is provided with the pre-embedded steel slab that is weldingly connected with it.
The utility model compared with prior art has following beneficial effect to be:
1. gather materials on the spot, can reuse, construction cost is low, and is pollution-free;
2. simple in structure, dismounting is simple and convenient;
3. required supporting steel pipe is the quarter butt stress system, stablizes, stress deformation is little, safe and reliable, and good effect is played in the protection of box beam flange plate.

Among the figure: 1. pre-embedded steel slab; 2. supporting steel pipe; 3.T beam support pinner; 4.T beam block; 5. pedestal steel plate; 6. case beam block; 7. bridge formation machine; 8.T type beam; 9. bridge formation machine track; 10. case beam; 11. cap; 12. concrete pillar.
The specific embodiment
The bridge transition cross T-shaped side bar that the utility model provides is installed the rigid support device, its structure as shown in Figure 1, Figure 2, Figure 3 and Figure 4: form by pre-embedded steel slab 1, supporting steel pipe 2, foundation means and installing mechanism.
Described foundation means is made up of concrete pillar 12, cap 11, the pedestal steel plate 5 of structure under the bridge, and wherein: cap 11 rests on the concrete pillar 12.Pedestal steel plate 5 lies in cap 11 ends, and this place must be with sander with the cap surface finish and guarantee that absolute altitude is on same horizontal plane.
Described supporting steel pipe 2 is a spiral steel pipe, and referring to Fig. 1: its lower end is welded on the pedestal steel plate 5; Its upper end is welded on below the pre-embedded steel slab 1, to support the frange plate cage of reinforcement of case beam 10.When vertically placing, this supporting steel pipe guarantees circumference on same horizontal plane, and cuts into groove that fully welding is full with pedestal steel plate 5 with pre-embedded steel slab 1, supporting steel pipe 2 for favourable supporting steel pipe 2 with oxygen welding.This supporting steel pipe is the quarter butt stress system, and its size is generally long 2.5m, diameter phi 500 and wall thickness 5mm.
Described pre-embedded steel slab 1 has two, referring to Fig. 3 and Fig. 4: after treating the 10 frange plate template installations of case beam, on template and in pedestal steel plate 5 vertical position levels, first pre-embedded steel slab is installed, first pre-embedded steel slab put level, guarantee that four footmarks in its bottom surface are high consistent, second pre-embedded steel slab is installed above first pre-embedded steel slab simultaneously, second pre-embedded steel slab is welded on the box beam flange plate cage of reinforcement, and guarantee second pre-embedded steel slab end face level, the absolute altitude of second pre-embedded steel slab is consistent with case beam 10 frange plate end face concrete absolute altitudes, helps the track sleeper and props up the pad level.The bottom of case beam 10 rests on the cap 11.
Described installing mechanism is made up of bridge formation machine 7, bridge formation machine track 9, T type beam 8 (side bar), and is shown in Figure 4 as Fig. 3: bridge formation machine track laterally is placed on the case beam 10, and vertical with the bridge floor center line.Prop up poppet bridge machine track 9 at first pre-embedded steel slab 1 end face with sleeper, make bridge formation machine track 9 keep level, the bridge formation machine 7 T type beam 8 of slinging laterally moves on to case beam limit portion slowly from case beam 10 middle parts, mobile then bridge formation machine overhead traveling crane is traversing in place with T type beam once more, transfer on the T beam support pinner 3, by T beam block 4 location, and temporary fixed.
The utility model is a kind of load-bearing rigid support device that a kind of long-armed frange plate that solves case beam 10 is not subjected to vertical active force; facts have proved: T type beam 8 (side bar) installation processes and the all-the-way tracking that carries out in place are when checking; the long-armed frange plate of not finding case beam 10 occurs rich down; any crack does not appear in this frange plate end face root, and the case beam obtains intact protection.Side bar can be in place, reach and prevent that frame sedan-chair machine from installing the purpose that the anti-bridge formation pusher side of bridge transition cross T-shaped side bar turns over, this device plays good result.
