Abstract
The utility model relates to a bridge engineering builds the field, specifically is a cast -in -place simple box girder removes and sprays maintenance canopy device, solves the problem that there is above -mentioned a great deal of defect in the artifical watering maintenance of current roof beam body adoption, include the english truss of laying along the case liang liang body vertical orientation interval, even as an organic whole every english truss below both sides sets up the pole setting in order to constitute maintenance canopy main couple through the reinforcing bar respectively for the top of adjacent english truss and both sides, and spray set is laid by the walking wheel of driving motor control, english truss below interval to the installation of pole setting lower extreme, and case liangliang body surface parallel is provided with the track of mutually supporting with each walking wheel. Rational in infrastructure, novel structure is unique, and simple process is swift in the preparation, preparation low cost, and the flexible operation convenience, labour saving and time saving can carry out wet maintenance entirely to concrete beam, prevents effectively that shrinkage crack from appearing in the concrete, guarantees roof beam physique volume, not only saves the manual work, and maintenance effect is estimated in can also be better reach.
Description
Technical field
The utility model relates to bridge engineering construction field, is specially a kind of cast-in-place simple supported box beam and moves spray maintenance shed device.
Background technology
After bridge concrete pouring construction, all adopt the way of artificial watering maintenance to prevent concrete cracking at present. But the maintenance of manually sprinkling water usually can not meet its maintenance effect in curing age, and labor intensive extremely. While manually beam body being sprinkled water to maintenance, need water pipe to spray beam body, maintenance one hole beam is consuming time longer comprehensively, especially, in the time that simple supported box beam is produced continuously, tends to occur the poor situation of last hole He Houyi hole beam maintenance sparge pipe. Known, if beam body concrete can not be subject to good maintenance within curing period, very easily there is beam body concrete face checking, concrete strength rises slowly early stage, finally affects beam weight. Therefore in the urgent need to research and develop simple fast, the flexible and convenient operation of a kind of with low cost, technique, time saving and energy saving, can carry out complete wet-cured spray curing means continuously to beams of concrete.
Summary of the invention
The utility model adopts artificial watering maintenance to have the problem of above-mentioned many defects in order to solve existing beam body, provides a kind of cast-in-place simple supported box beam to move spray maintenance canopy.
The utility model is to adopt following technical scheme to realize: cast-in-place simple supported box beam moves spray maintenance canopy, comprise the English truss of laying along box girder body longitudinal direction interval, the top of adjacent English truss and both sides are connected as a single entity to form maintenance canopy main couple by reinforcing bar respectively, both sides, each English truss below arrange vertical rod, the road wheel by drive motors control is installed in vertical rod lower end, spray equipment is laid at interval, English truss below, and box girder body surface is arranged with the track cooperatively interacting with each road wheel in parallel.
Described maintenance canopy main couple outer surface is equipped with geotextiles, and geotextiles can be used to increase the stability of maintenance canopy main couple entirety, also can ensure the evaporation time delay of beam body curing period simultaneously.
In the drive motors control loop of described each road wheel, be serially connected with gauge tap, for controlling advancing of all road wheels, simple and convenient.
Described spray equipment forms by hanging on some spray heads of below, English truss inside and the shower being connected with spray head, on the supply channel of shower, is serially connected with gauge tap.
Adopt structural design of the present utility model, utilize the stable feature of triangular truss structure, multiple English trusses are connected as a single entity as maintenance canopy main couple with reinforcing bar, bottom arranges road wheel, improve travelling performance, and can realize porous maintenance by track advancing; Can regulate spray equipment interval, carry out full wet curing simultaneously.
Compared with prior art, the utility model project organization is reasonable, modern design uniqueness, manufacture craft simple and fast, cost of manufacture is cheap, flexible and convenient operation, time saving and energy saving, can carry out full wet curing to beams of concrete, effectively prevent that contraction crack from appearring in concrete, ensure beam weight, not only save manually, can also reach preferably expectation maintenance effect.

Detailed description of the invention
Cast-in-place simple supported box beam moves spray maintenance canopy, as shown in Figure 1, 2, comprise the English truss 2 of laying along box girder body 1 longitudinal direction interval, the top of adjacent English truss and both sides are connected as a single entity to form maintenance canopy main couple by reinforcing bar 3 respectively, maintenance canopy main couple outer surface is equipped with geotextiles, both sides, each English truss below arrange vertical rod 4, and the road wheel 5 of being controlled by drive motors 6 is installed in vertical rod lower end, in drive motors 6 control loops of each road wheel, is serially connected with gauge tap 8; Spray equipment is laid at interval, English truss below, box girder body surface is arranged with the track 7 cooperatively interacting with each road wheel in parallel, spray equipment forms by hanging on some spray heads 9 of below, English truss inside and the shower 10 being connected with spray head, on the supply channel of shower, is serially connected with gauge tap.
When concrete making, English truss is laid together along beam longitudinal pitch 4m ~ 5m, then by welding vertical rod, install road wheel and and the bottom track of locating in advance connect into entirety, looking for professional person's mounted motor and spray equipment, must lean on good integrity by firm body, and unification is being controlled respectively by gauge tap, take the circumstances into consideration to consider 3-5 shower nozzle of each English truss place installation according to simply supported beam deck-siding, finally above main couple, laying geotextiles at this increases the evaporation time delay of stability and curing period.
Above-mentioned material can utilize the steel such as reinforcing bar or channel-section steel, I-steel to arrange in pairs or groups voluntarily, and part can utilize construction waste material to process, and so both can make rational use of resources, and also can save material cost.
