Abstract
The invention relates to a fully assembled emergency combination bridge device, which is formed by splicing a plurality of bridge components, wherein each bridge component comprises a bottom steel plate, a corrugated steel web, a flange undertaking steel plate, a prefabricated concrete standard part and a steel bridge deck plate; the bottom steel plates are connected with the corrugated steel webs through connecting pieces; the corrugated steel webs are connected with the flange undertaking steel plates through the connecting pieces; the prefabricated concrete standard parts are arranged in the flange undertaking steel plates; the prefabricated concrete standard parts are connected with the steel bridge deck plates through fastening bolts; and the bottom steel plates of two adjacent beam components are connected through a bolt. Compared with the prior art, the fully assembled emergency combination bridge device has the advantages of large bearing capacity, convenience in transportation, reusability, high assembling speed, safety and reliability and the like.
Description
Technical field
The present invention relates to a kind of bridging apparatus, especially relate to the emergent combined bridge device of a kind of full assemble type.
Background technology
Place in a lot of constructions, or run into the place of disaster, for short-term transportation or rescue and relief work, need to set up easy bridge, and will guarantee the needs that are open to traffic, if yet cast-in-situ bridge, need long time maintenance, not only incur loss through delay the opportunity of duration or rescue and relief work, and these bridges after using not as permanent building, need to remove the waste of the material that causes that it is enough.
A direct prefabricated monoblock beam that reaches tens meters, if for rescue and relief work, poor transport first, very high to lifting requirements in addition, big machinery cannot arrive appointed place fast, if the suspension bridge for constructing, with big machinery lifting, increased on the contrary extra-pay, very uneconomical.
Existing full assemble type bridge, use for reference the form of the firm truss combining structure of shellfish thunder, structure is very complicated, need to there is the technician of professional knowledge to carry out assembled, and this all steel trussed construction, if adopt welding completely, cannot remove recycling, if all use bolt to connect, because rod member is too many, cause connecting bolt number huge, construction and the speed of removing are very slow; In addition, the firm truss of shellfish thunder departs from lifting machine completely, although big machinery cannot arrive, but some small-size hoisting machine tool can use in time, fail to suit measures to local conditions, and it adopts full steel structure, bridge cost is more expensive, is unsuitable for popularizing and being generalized to general bridge construction.
Summary of the invention
Object of the present invention be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of bearing capacity large, be convenient to transport, reuse, full assemble type that assembled speed is fast, safe and reliable is met an urgent need combined bridge device.
Object of the present invention can be achieved through the following technical solutions:
A kind of full assemble type combined bridge device of meeting an urgent need, it is characterized in that, by a plurality of beam assemblies, be spliced, bottom each beam assembly comprises, steel plate, precast concrete standard component and steel bridge deck are accepted in steel plate, Wavelike steel webplate, the edge of a wing, described bottom steel plate is connected with Wavelike steel webplate by connector, described Wavelike steel webplate is accepted steel plate by connector and the edge of a wing and is connected, described precast concrete standard component is located at the edge of a wing and accepts steel plate inside, and described precast concrete standard component is connected with steel bridge deck by fastening bolt; The bottom steel plate of adjacent two beam assemblies is bolted.
The L-shaped structure of described connector.
The longitudinal section of described precast concrete standard component is T-shaped, and the width of its upper surface is 1.5～2m, and the width on its T shape protuberance surface is 1/2～2/3 of upper surface width.
The upper surface length of described precast concrete standard component is 2～4m.
Compared with prior art, the present invention has the following advantages:
1, need not be cast-in-place, complete precast assembly;
2, make full use of concrete compression and steel tension, the good characteristic of compressive property, utilizes Wavelike steel webplate, has greatly improved the bearing capacity of beam;
3, beam piece is divided into a lot of fritters, is convenient to transportation;
4, detachable, to reuse, the reference block that fritter is 2～4m, is convenient to assembled;
5, compared with the firm bridge of combination, bearing capacity is high, applicable to the truck operation of higher tonnage;
6, in completely assembled, take into account the use of small-sized machine, accelerated assembled speed;
7, in conjunction with rotation construction, assembled by different level stage by stage, without the problem of considering pier in water;
8, this structure is the combination of concrete and steel work, is easily converted to permanent structure and security reliability.
