Description
Technical field
The utility model relates to field of bridge construction, is specially one deck paving heat preservation construction device in winter.
Background technology
In bridge construction, the concrete of deck paving is because area is large and thin thickness, especially winter construction and health have certain difficulty, concrete is ability setting and harden under certain temperature condition in addition, carry out bridge deck concrete construction winter and can make concrete endure cold, and cannot make concrete coagulation, the contained moisture freezes such as soil, concrete, mortar, the easy embrittlement of constructional materials, brings many difficulties to building operations.Traditional cold weather concrete insulation protection adopts stove heat preservation construction, and the problem of its existence has: in (1) construction and need continuous coal in insulating process, complex operation, impact construction; (2) insulation stove produces volume of smoke, and construction environment is stuff, and easily poisoning, air pollution is serious; (3) near insulation stove local temperature higher, and away from local temperature lower, the uniformity of heating is bad, cause concrete construction quality be difficult to ensure.
Summary of the invention
The utility model adopts stove insulation in order to solve Deck Concrete Pavement construction in existing winter, has the problems such as complex operation, contaminated environment, homogeneous heating degree be bad, provide a kind of winter deck paving heat preservation construction device.
The utility model is to adopt following technical scheme to realize: winter deck paving heat preservation construction device, comprise by column, longeron, interval and be connected in the roof insulating support system that two truss crossbeams between longeron and some cross binding, vertical supporting form, two sides of roof insulating support system, two end faces and end face are coated with geotextiles insulation layer, Polypropylence Sheet insulation layer and tarpaulin waterproofing course from inside to outside successively, and inner side, roof insulating support system one end is provided with warm-air drier.
Described all truss beam weldings become the low bending in middle high two ends, at utmost increase the interior construction space of roof insulating in the situation that taking into account ceiling draining.
Described roof insulating support system below is installed and is laid on the road wheel that the guide rail on bridge floor cooperatively interacts, and like this, the construction speed that whole heat preservation construction device can be laid with bridge floor arbitrarily moves along track, easy to operate, time saving and energy saving.
Adopt structure design of the present utility model, adopt warm-air drier to heat environment in bridge floor and canopy, make temperature of shed reach code requirement, can reach the effect that bridge deck concrete in construction adds gentle moisturizing, in addition, insulation is made system bottom road wheel is installed, thereby attemperator need to be able to be moved according to construction, can have enough to meet the need use, peace is torn open conveniently, has the advantages such as cost is low, convenient construction, raising work efficiency.Adopting heat preservation construction device described in the utility model to carry out winter Surfacing Construction is a kind of novel construction method, compare former stove heating and thermal insulation, control insulation temperature of shed that can be more stable, and in roof insulating, be to heat more uniformly, can effectively ensure the concrete quality of deck paving.

Detailed description of the invention
Winter deck paving heat preservation construction device, as shown in Figure 1, 2, comprise by column 1, longeron 2, interval and be connected in the roof insulating support system that two truss crossbeams 3 between longeron and some cross binding, vertical supporting form, two sides of roof insulating support system, two end faces and end face are coated with geotextiles insulation layer 4, Polypropylence Sheet insulation layer 5 and tarpaulin waterproofing course 6 from inside to outside successively, and inner side, roof insulating support system one end is provided with warm-air drier 7.The low bending in high two ends in the middle of all truss crossbeams 3 are welded into.Roof insulating support system below is installed and is laid on the road wheel 8 that the guide rail on bridge floor cooperatively interacts.
When concrete making, warm-air drier employing section gold warm air curtain, product type: D-30, air quantity: 2500m3/h, wind speed: 2-3m/s, power of motor: 250W, heating power: 30KW.Roof insulating adopts diameter ф 50, ф 20 steel pipe weldings to be connected into support system, and outsourcing trilaminate material, is respectively building cloth, plastic sheeting and water-proof tarpaulin, roof insulating 4 root posts adopt ф 50 steel pipes, and 4 road wheels are installed under steel pipe, to promote when mobile roof insulating.Other columns and horizontal vertical supporting adopt ф 20 steel pipes, every a truss crossbeam of 3 meters of designs, truss crossbeam is also formed by ф 20 steel-pipe weldings, the low bending in high both sides in the middle of truss beam welding becomes, the maximum interior construction space that increases in the situation that taking into account ceiling draining.
Warm-air drier heat preservation construction step:
(1) beam face cleaning
To bridge deck dabbing, with artificial floating bits and the drifting dust removed, then clean bridge floor with giant.
Before mating formation, beam face is checked, bridge floor should be smooth, coarse, dry, clean and tidy, must not have dust, foreign material or greasy dirt, and deck transverse slope should meet the requirements.Undesirable processing, is polished or is studied for a second time courses one has flunked thin projections or pit.
(2) mobile heat preservation construction device of the present utility model
Mobile heat preservation construction device, to the beam face of having cleared up, is then installed warm-air drier, when installation, will carry out earth leakage protective measure.After warm-air drier Installation and Debugging, open warm-air drier, keep temperature of shed 10 DEG C of left and right.
(3) Surfacing Construction
Waterproof Layer Spreading of Bridge Surface adopts Chlorinated polyethylene plastic sheets for waterproofing, and topping adopts C40 microlith fibrous concrete.
When construction on the beam face of having cleared up evenly brushing one deck polyurethane water-proof paint as cementing agent, brushing thickness is not less than 1.5mm, then the surperficial paving Chlorinated polyethylene plastic sheets for waterproofing brushing in painting, installation of membrane is from one end, and bridge floor laterally sequentially carries out paving from low to high.Waterproof roll edge and beam body seam crossing adopt polyurethane water-proof paint to carry out edge sealing processing, and edge sealing width is not less than 100mm, and brushing thickness is not less than 2mm.
(4) insulated curing
Maintenance adopts watering maintenance, and insulation temperature of shed ensures that first day is surveyed once every about 4 hours 10 DEG C of left and right, after the initial set of topping concrete, surveys once every 8 hours.After three days, heat preservation construction device is removed, and adopts engineering cotton-wadded quilt covering curing 14 days.
