Description

Device for bridge deck construction and construction method thereof
Technical Field
The application relates to the field of bridge construction equipment, in particular to a device for bridge deck construction and a construction method thereof.
Background
Bridge deck pavement refers to a process of paving a concrete protective layer on a bridge deck, which is used for preventing wheels from directly wearing a bridge deck, diffusing wheel loads and providing a smooth and anti-skid running surface for vehicles.
Three roller spreading eveners are also called three roller vibration roof beams, a concreting equipment that often uses in the bridge deck pavement, as shown in fig. 1, a three roller vibration roof beam includes support body 1, support body 1 includes two fixed plates 11, the level has arranged first roller 2 in proper order between two fixed plates 11, second roller 3 and third roller 4, wherein first roller 2 individual drive is rotatory, first roller 2 is used for stirring the concrete surface of pouring, play the effect of carrying the thick liquid, second roller 3 rotates with third roller 4 synchronous, second roller 3 can produce the vibration, be responsible for with concrete pressure peaceful compaction, third roller 4 provides drive power and orders about support body 1 and gos forward.
At present, the bridge deck pavement mainly adopts a construction mode that two concrete base bands 6 are respectively poured on two sides of a bridge deck in advance, and the two base bands 6 are equivalent to side moulds for pouring concrete on the bridge deck and are used as moving tracks of a vibration beam. After the base bands 6 are hardened, the vibrating beam is erected between the two base bands 6, the uniform ends of the second roller shaft 3 and the third roller shaft 4 are lapped on one base band 6, and the first roller shaft 2 is placed on one side of the vibrating beam in the advancing direction. During construction, concrete is poured on the bridge deck, the vibration beam moves forwards, the concrete after being lifted by the first roller shaft 2 is compacted by the second roller shaft 3 and is flush with the surface of the base band 6 in a pressing mode, and finally the base band 6 and the newly poured concrete form a pavement layer of the bridge deck.
When concreting, constructor usually can pour the concrete thickness between the baseband a little bit to the vibrating beam can fully contact the concrete of newly pouring, and then compresses tightly the concrete. However, in a construction site, the problem that the poured concrete is locally too thick or the slump of the concrete is small often occurs, the second roller cannot press down the concrete quickly when moving forwards in the axial direction, the vibration beam can be jacked to move forwards, the surface of the part of concrete cannot be flush with the surface of the base band, therefore, a constructor needs to retreat the vibration beam for a certain distance, and after the part of concrete is shoveled by a worker, the vibration beam is driven to move forwards, so that a large amount of time is wasted, and the construction efficiency of pouring the bridge deck concrete is reduced seriously.
Disclosure of Invention
In order to improve the construction efficiency of pouring concrete on the bridge deck, the application provides a device for bridge deck construction and a construction method thereof.
On the one hand, the device for bridge floor construction that this application provided adopts following technical scheme:
the utility model provides a device for bridge floor construction, establish the first roller between two fixed plates including two fixed plates and level in proper order, second roller and third roller, be equipped with pushing equipment between first roller and the second roller, pushing equipment is including connecting the horizontal bottom plate between two fixed plates, it is provided with the push pedal to slide on the bottom plate, the direction of sliding of push pedal is parallel with the direction of arranging of first roller and second roller, still be equipped with the promotion subassembly that orders about push pedal reciprocating motion between two fixed plates.
Through adopting above-mentioned technical scheme, the mounted position of steerable bottom plate is a little higher than the position take the altitude of second roller axle bottom side, at the in-process that third roller axle drive was advanced, the concrete that is higher than bottom plate position height will be scraped and pile up on the bottom plate, when the push pedal bears partial concrete and moves forward, order about push pedal reciprocating motion through promoting the subassembly, the push pedal can be with being in partial concrete on the bottom plate constantly push away from the bottom plate, make the concrete on the bottom plate be difficult to pile up the rear of crossing the push pedal. So the second roller is when contacting the concrete, and the concrete has been scraped certain thickness by bottom plate and push pedal, even if under the less condition of slump of concrete, because the thickness of concrete reduces, the second roller can flatten the concrete more easily, needs the probability that the device receded alright reduce, and then can improve the efficiency of construction that the bridge floor pour the concrete.
