The utility model is realized the technical scheme that above-mentioned purpose takes: a kind of horizontal assembled Wavelike steel webplate combination T beam bridge, comprise multiple prefabricated Wavelike steel webplate T beam elements and by contiguous prefabricated Wavelike steel webplate T beam element by being longitudinally connected to form the crossbeam of the continuous prefabricated Wavelike steel webplate T beam of porous, be connected with top board lower edge steel plate in the wet seam of the top board of described two adjacent prefabricated Wavelike steel webplate T beam elements lower surface.
Precast T-Beam described in the utility model unit is prefabricated Wavelike steel webplate.
On top board lower edge steel plate described in the utility model, be provided with multiple pegs.
Peg described in the utility model and top board lower edge steel plate are for being welded to connect.
Top board lower edge steel plate described in the utility model is connected by welding or bolt with described Precast T-Beam unit.
On abutment pier shaft described in the utility model, be provided with bearing or embedded bar.
It is described in the utility model that on support, longitudinally cast pier head piece or prefabricated pier head piece adopt splicing to connect into entirety to form continuous beam on many supports or continuous rigid frame.
The utility model has following advantage compared with prior art:
(1) T beam adopts Wavelike steel webplate combining structure, has given full play to the service efficiency of steel and concrete material, has reduced amount of concrete, has alleviated Precast T-Beam weight, energy-conserving and environment-protective, and economic performance is good.
(2) the employing of structural key parts Wavelike steel webplate combination T beam is prefabricated, is connected to form Wavelike steel webplate T beam bridge by cast-in-place wet seam, is conducive to batch production processing, ensures construction quality, accelerating construction progress.
(3) laterally the lower edge steel plate of wet seam can, directly as the template of cast-in-situ concrete, have been avoided the operation of dismounting template compared with the wet seam of ordinary concrete, has reduced the working amount of wet seam, has shortened construction period, has accelerated construction speed.
(4) cancel pier cap beam, expanded bridge pier moulding application type, can design according to aesthetic requirement the bridge pier of beautiful design, greatly promoted the landscape function of bridge.
(5) only set up a small amount of support in pier shaft both sides, and support and template recoverable, cost-saving, improve economy.
(6) in work progress, can keep road under bridge, social benefit is good.
(7) can be used for the bridge of uncovered beam bridge pier, also can be used for having the bridge of bent cap bridge pier, expanded application.
