The specific embodiment
Bridge formation machine provided by the invention is installed the anti-bridge formation pusher side turning-up devices of bridge transition cross T-shaped side bar, its structure such as Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4: be made up of pre-embedded steel slab 1, supporting steel pipe 2, foundation means and installing mechanism.
Said 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.
Said 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.
Said 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, and second pre-embedded steel slab is welded on the box beam flange plate cage of reinforcement, and guarantees 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.
Said 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 like 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, it is traversing in place with T type beam once more to move bridge formation machine overhead traveling crane then, transfers on the T beam support pinner 3; By T beam block 4 location, and temporary fixed.
The present invention is a kind of load-bearing rigid support device that a kind of long-armed frange plate that solves case beam 10 does not receive vertical active force; Facts have proved: when T type beam 8 (side bar) installation processes and in place are carried out the all-the-way tracking inspection; 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.Can side bar be in place, reach and prevent that the bridge formation 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.
