Preferably, the slit width of the longitudinal spliced seam is 4~6cm.
The utility model is longitudinally spelled width to overpass and is connected using TST lastics filled layer with adhesive layer, and deck paving is made
Non-individual body is formed, without vehicle phenomenon is jumped when driving, comfort is preferable.TST lastics can be absorbed due to temperature and traffic loading work
It is displaced with the floorings of generation, it is ensured that surface layer will not cracking damage.Meanwhile construction is simple, short time limit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that overpass provided by the utility model spells wide structure.
Specific embodiment
As shown in Figure 1, a kind of overpass spells wide structure, which includes old bridge module, new bridge plate component and connects
Component is stitched, the old bridge module includes old bridge plate 2 and the old pave-load layer 1 mated formation on old bridge plate 2, the new bridge
Component includes new bridge plate 3 and the new pave-load layer 6 mated formation on new bridge plate 3, and the old bridge plate 2 and new bridge plate 3 are horizontal
Longitudinal spliced seam 5 is formed between, forms reserved seam slot between 5 transverse direction of the old pave-load layer 1 and new pave-load layer；The seam
Component includes waterstop 4, TST lastics filled layer 7 and adhesive layer (11,61), and the waterstop 4 is laid on described indulge
To on splicing seams 5, the TST lastics filled layer 7 is for filling the reserved seam slot, and it passes through the first adhesive layer respectively
11 and second adhesive layer 61 it is be bonded with old pave-load layer 1 and the generation of new pave-load layer 6.
The utility model in one embodiment, the waterstop is U-shaped neoprene waterstop, and the U-shaped chlorine
Buna waterstop is matched with longitudinal seam width.
In another embodiment of the utility model, the adhesive layer in old pave-load layer and new pave-load layer side by brushing
TST adhesive forms.
In another embodiment of the utility model, the TST lastics filled layer is that rubble and the TST colloidal sol of heat fill
Mix is divided to form；The old pave-load layer and new pave-load layer are concrete pavement layer.
In the utility model further embodiment, in the longitudinal spliced seam of new and old beam slab, general slit width 4-6cm is first laid with U
Shape neoprene waterstop, in seam two sides Deck concrete pavement layer side brushwork adhesive, then in reserved joint gap
(every side 35cm) is laid with TST lastics bonding material (referring to Fig. 1) in range.
In addition, TST lastics filled layer is the structure that TST lastics is filled in that reserved seam slot is formed, in the prior art
Disclosed TST lastics, in order to preferably help to understand the implementation of the utility model, can be mentioned using in the present invention
For following construction procedure:
Step 1: preparation of construction.Groundwork include on the outside of old bridge anticollision barrier cut off, new Deck Concrete Pavement, only
Water band, TST lastics, mechanical preparation.Before new and old old bridge splicing, first the outside anticollision barrier of old bridge is cut off, and with clearly
Water rinses dry adornment without surface dust and discrete particles, and groove face is cleared up to the pave-load layer of old bridge.When new deck paving, seam groove width is reserved
It spends (35cm or so).Waterstop uses U-shaped neoprene waterstop, U-shaped to match with new and old joint of bridge width, two sides and beam
Plate lap width is no less than 10cm.
