The present invention proposes under the prefabricated notion of industrialization of construction industry; Steel bridge deck is prefabricated in the factory; Make in the workshop of control relatively more easily indoor, under the environment of stricter limit temperature, humidity, to steel plate eliminate rust, anticorrosion, bonding, epoxy asphalt mixture making, maintenance; On engineering structures, weld the steel bridge deck of accomplishing epoxy asphalt pavement again; And carry out PROCESS FOR TREATMENT such as the welding, rust cleaning of seam crossing, anticorrosion, joint filling, make the technological difficulties of paving steel bridge deck under the environment of indoor relatively easy control, accomplish, thus realize fast, efficient, guarantee that the steel bridge face epoxy of quality mats formation.
At present, national industrialization of construction industry is in progressively the propelling.The assemblingization rapidly and efficiently of bridge construction will receive the attention of design, construction and owner unit.The modernized prefabricated epoxy asphalt mixture bridge steel bridge deck technology of mating formation simultaneously; Can adopt large-scale indoor industrially production model; In computer program control down, the cutting of completion sheet material, cutting, die mould, welding, rust cleaning, anticorrosion, epoxy asphalt mixture is mated formation, maintenance.Also can be implemented in the factory's indoor environmental condition control under the computer control condition.And under the logistics transportation technology platform model of changing in modern times, realize transporting of product to bridge construction site; Assembling fast at the construction field (site); Accomplish the bridge construction process fast and efficiently.
Summary of the invention
Patent of the present invention is to the weak point in the above background technology; Epoxy asphalt pavement steel bridge deck under the prefabricated notion of a kind of industrialization is provided; Being intended to solve in the present engineering reality steel bridge face, to carry out the epoxy asphalt pavement difficulty of construction big; Ambient conditions requires harsh, and maintenance is difficult, the wayward technical barrier that waits of quality.The prefabricated production of industrialization of the steel bridge deck through prefabricated epoxy asphalt pavement layer realizes the modernization of paving steel bridge deck.
The present invention is achieved through following technical scheme:
A kind of steel bridge deck of prefabricated epoxy asphalt pavement layer; Comprise Orthotropic Steel Bridge Deck and epoxy asphalt pavement layer; It is characterized in that; The steel bridge deck of described prefabricated epoxy asphalt pavement layer is the steel bridge deck of a kind of prefabricated epoxy asphalt pavement layer do not produced at the construction field (site), and the bottom of this steel bridge deck is provided with orthotropic steel bridge deck 6, is disposed with rust preventive coating 5, adhesive linkage 4, epoxy asphalt pavement layer 3, adhesive linkage 2 and surface layer 1 above the orthotropic steel bridge deck 6;
Described surface layer 1 is that epoxy asphalt pavement layer or SMA are the asphalt-mastic-broken stone mixed layer;
The steel bridge deck of described prefabricated epoxy asphalt pavement layer is provided with the field joint of the 50～500mm of 2～4 places on each prefabricated component.Its field joint position, promptly the splicing position of pairwise orthogonal opposite sex steel bridge face 6 is not provided with any structure layer on the orthotropic steel bridge deck 6 at this position.
The board dimension of said steel bridge deck is: long 100mm～100000mm, wide 100mm～50000mm, thick 10mm～1000mm.
The invention has the beneficial effects as follows; The advantage of the steel bridge deck set modern industrialization complete set technology of the prefabricated epoxy asphalt pavement that is provided; Solved that on-the-spot epoxy asphalt pavement difficulty of construction is big, ambient conditions requires harsh; Maintenance is difficult, and the uppity technical barrier of quality has been realized the modernization of prefabricated production of industrialization and paving steel bridge deck.

The specific embodiment
The steel bridge deck of a kind of prefabricated epoxy asphalt pavement layer of the present invention is a kind of steel bridge deck of a kind of prefabricated epoxy asphalt pavement layer of not producing at the construction field (site).Like Fig. 1, shown in Figure 2, the bottom of this bridge floor is provided with orthotropic steel bridge deck 6, is disposed with rust preventive coating 5, adhesive linkage 4, epoxy asphalt pavement layer 3, adhesive linkage 2 and surface layer 1 above the orthotropic steel bridge deck 6.
Described surface layer 1 is epoxy asphalt pavement layer or SMA (asphalt-mastic-broken stone mixed layer); If topping laying SMA can be prefabricated in the factory, also can directly lay at the construction field (site);
The steel bridge deck of described prefabricated epoxy asphalt pavement layer; Its field joint position; Be the splicing position of pairwise orthogonal opposite sex steel bridge face 6, the top any structure layer that is not provided with of this outside, position 50～500mm is provided with 2～4 place's joints according to different engineerings position on each prefabricated component.
Preparation method of the present invention is conventional preparation method; After steel plate cutting, die mould, welding; Process the Orthotropic Steel Bridge Deck that meets requirement of engineering; Mating formation of rust preventive coating 5, tack coat 4 and epoxy asphalt pavement layer 3 accomplished one by one through after injection or centrifugal blast cleaning are handled completely in the surface, and maintenance makes bituminous epoxy accomplish curing in curing kilns.Wherein every steel bridge deck joint area is all reserved 50-500mm and is not laid epoxy asphalt concrete and other structure, wait until the job site welded and installed after, carry out the processing of mating formation of plate seam by the existing epoxy asphalt concrete mode of mating formation again.
