Description
Technical field:
The present invention relates to a kind of paving systems of Steel Bridge Deck, more particularly, to the three-dimensional paving system of steel bridge deck asphalt mixture.
Background technique:
Traditional Steel Bridge Deck cast asphalt concrete, which is mated formation, to be hung in engineering site steel girder segment using the method for live making
Entirety is carried out after dress splicing to pave, and is that formula asphalt to be cast is transported to existing when casting type asphaltic mixture paves
After, mixture laying is carried out using flat paver is scraped.
To improve steel deck paving packing quality, shorten and the construction period and raise labour productivity, develops a kind of assembling and apply
Work method: after steel girder segment produces and try to spell in girder steel construction factory, derusting by sandblasting is carried out in factory, erosion resistant coating is applied
Work, water-proof system construction and lower layer's casting type asphaltic mixture construction of mating formation, the steel girder segment then mated formation to band are transported to existing
And after lifting splicing, the reserved location processing of mat formation upper layer construction and seam, structure.
But since steel girder segment height commonly reaches 5m or more, and steel girder segment stress is not perfect and should not bear a heavy burden, and leads
It causes casting type asphaltic mixture that can not be promoted to steel girder segment top surface, can not be transported to paver front end, paver also can not be
Girder steel top surface paves.
A kind of paving steel bridge deck method of assembling is disclosed in Chinese patent CN106192757A comprising five steps
Suddenly, wherein first three step is to construct in factory, by box girder transport to bridge scene after construction, two after carrying out after installing
A step, five steps are respectively as follows: 1) steel bridge deck processing；2) water-proof tack coat is constructed；3) mat formation lower layer construction (cast-type
Asphalt)；4) Steel Bridge Deck assembly and connector are handled；5) mat formation upper layer laying.
Water-proof tack coat construction is carried out to steel girder segment in factory and is mated formation although referring to use in above-mentioned patent
Lower layer's construction, but it is not disclosed in factory and how to realize and construct to it, does not provide specific form of construction work and equipment, and
Existing steel girder segment height is typically up to 5m or more and should not bear a heavy burden, and Yao Shixian carries out so high steel girder segment in factory
Construction is current yet unresolved issue.
Summary of the invention:
The purpose of the present invention is to provide a kind of to realize that constructs in factory stands to steel girder segment that is highly higher and should not bearing a heavy burden

Also, it is additionally provided with cooker vehicle 6 in the bottom of the lifting device, the cooker vehicle 6 can freely walk simultaneously
The feeding into the transhipment hopper 4.
Using the Steel Bridge Deck casting type asphaltic mixture solid paving system of the prefabricated construction of the present embodiment, using
Cheng Zhong can be sequentially included the following steps:
1) steel girder segment 7 to be paved is placed below three-dimensional paving system, between specially two sliding rails 1, sliding rail gantry crane 2
Lower part, in case paving；
2) cooker vehicle 6 pours into casting type asphaltic mixture in transhipment hopper 4；
3) the transhipment hopper 4 for filling mixture is promoted to working depth by lifting device 5；
4) guide rail of the transhipment hopper 4 along 2 top of sliding rail gantry crane is moved to above paver 3；
5) mixture is poured on 3 front of paver by transhipment hopper 4, and is walked with paver, uniform discharging；
6) paver 3 moves ahead, by mixture laying in bridge floor；
7) in paving process, transhipment hopper 4 is travelled to and fro between cooker vehicle 6 and lifting device 5, realizes the supply of mixture.
Wherein, in order to reach more efficient, quality is higher to pave, and before paving, makes the steel girder segment 7 with lane cross
To mode be placed between two sliding rails 1.Then entire bridge floor is divided into several breadth along track direction, every width includes several
Lane, paver width is adjustable, and to adapt to different breadth, paver 3 is carried out along track direction first when paving, i.e., described
Paver 3 slides along the transverse direction first, and after the breadth that paved, sliding rail gantry crane 2 is moved along sliding rail, and paver 3 is moved to down
One breadth paves.In paving process, 6 pairs of transhipment hoppers 4 of more cooker vehicles is needed to carry out the supply of mixture, to guarantee
It continuously paves, when the breadth to pave is larger, the 2 settable ring-shaped guide rail in top of sliding rail gantry crane takes more hoppers at this time
Circulation feed.
Finally, the steel girder segment finished that will pave is transported to carry out assembled to scene, and mat formation and upper layer construction and to connect
Seam.It completes, can be improved indoors in this way, quality requirement highest, the difficulty that paves maximum and most important lower layer are paved to place
Spreading quality and efficiency.
In addition, another embodiment as the present embodiment, being also provided in the distributing device lower end of the paver can

In distributing device lower end, this is that have card slot, connector can be snapped onto card slot etc..
In addition, the pull rod front end of the hydraulic pressure draw-bar connects the spray gun, and pull rod front end is provided with an inverted U-shaped part
12, the inverted U-shaped part lower part connects the spray gun, and top is connect with the connecting rod sliding rail 11 that connector bottom is arranged, to protect
The position for demonstrate,proving spray gun, avoids its overweight downslide, influences spraying effect, damages hydraulic pressure draw-bar.
Using above-mentioned spray gun, walks using the longitudinal walking and the lateral of paver of portal frame, realize paving steel bridge deck
The automatic spraying of first layer methacrylic acid water-repellent paint, and in spraying process, hydraulic pressure draw-bar moves ahead anti-along portal frame
Direction pulls spray gun mobile, to guarantee that spraying profile perpendicular to portal frame direction of travel, avoids the inclination of spraying profile.
Using the three-dimensional paving system for Steel Bridge Deck of the present embodiment, indoor booth is being carried out to large-scale Steel Bridge Deck segment
Paving, especially for the steel bridge segment of 5m or more, can be good at realizing paving to the casting type asphaltic mixture of its lower layer,
And it will not allow Steel Bridge Deck stress or weight bearing, ensure that the intensity of itself.
In addition, using three-dimensional paving system of the invention, can full automatic control paving thickness, the painting for different demands
The Steel Bridge Deck of layer or different demands, can adjust paving thickness, and applicability is wider.Moreover, by the row of paver and portal frame
It walks, realizes the automatic spraying of Steel Bridge Deck first layer water-repellent paint.
Using the paving system of the present embodiment, when being not only able to avoid paving at the scene by weather (such as strong wind, rainfall, frost,
Snow etc.), the influence of temperature, humidity, dust storm, haze, additionally it is possible to avoid that (live spreading machineization is horizontal by artificial influence
It is low, artificial more)；Enable steel bridge segment in constant temperature and humidity and is not carried out the work that paves by the interior of weather, climatic effect, and
And high degree of automation, greatly improve spreading quality and efficiency.
