Background technology
With the development of highway construction in recent years, the construction of different types of rridges also day by day increases, the group of most of prefabrication and lifting Close beam (plate) bridge carries out static test before beam (plate) is set up to single-beam (plate), and static test becomes detection design to single-beam (plate) is Whether no safety, construction quality meet the important means of specification and design requirement.Accumulation load method the most frequently used at present uses concrete Prefabricated section or steel strand wires are loaded directly in box beam top surface, draw materials conveniently, it is simple to operate, it is not necessary to too big input.But load, unload Carry lifting high labor intensive, hanging device to have high demands, detection cycle length, easily limited by place, so as to cause test efficiency it is relatively low, Precision is not high.
The content of the invention
To solve above-mentioned technical problem, this utility model provide a kind of loading flexibly, be disturbed it is little quiet for single-beam Carry the charger of test.
A kind of charger for single-beam static test described in the utility model, the charger include box beam 1, It is leveling steel plate 2, hydraulic jack 3, concrete pad 4, carrier bar 5, anchor beam 6, centre-hole jack 7, steel strand wires 8, P anchors 9, general Logical reinforcing bar 10, cushion cap 11 and sleeper 12;1 two bottom sides of the box beam are supported by sleeper 12;3 symmetrical placement of hydraulic jack is in case Near 1 top surface span centre of beam, thereon, underneath with 2 levelling of leveling steel plate;Concrete pad 4 is located at lowers plain plate 2 and box beam 1 Between top surface;The apical support of hydraulic jack 3 is in the center of 5 bottom surface of carrier bar;5 upper surface both sides of carrier bar are provided with anchor Beam 6;Centre-hole jack 7 is disposed with above anchor beam 6;Centre-hole jack 7 carries out one-end tension to 8 stretching end of steel strand wires;Steel 8 fixing end of twisted wire is fixed on the regular reinforcement 10 of 11 bottom of cushion cap by P anchors 9.
A kind of charger for single-beam static test described in the utility model, the steel strand wires 8 are passed perpendicularly through and are held Carrier beam 5.
A kind of charger for single-beam static test described in the utility model, the steel strand wires 8 are perpendicularly fixed at Cushion cap 11.
When in use, can carry out in accordance with the following steps:1) shift to an earlier date pre-buried good prestress wire during bearing platform construction, bury Steel Shu Caiyong P anchors in cushion cap, P anchorings are scheduled on the reinforcing bar of cushion cap bottom;2) leveling steel plate is installed successively at the top of box beam And hydraulic jack, hydraulic jack is arranged symmetrically along box beam span centre;3), after carrier bar is in place, anchor beam is connected with carrier bar welding Connect;4) arrange centre-hole jack on anchor beam, centre-hole jack carries out tensioning to steel strand tension end, carrier bar put more energy into after shape Into counterforce device.
Compared with prior art, single-beam static test loading device described in the utility model is opened by arranging on anchor beam Anchored end is set on pull end, cushion cap, the counteracting force of box beam static load is directly undertaken by cushion cap, box beam static test is significantly improved Efficiency and performance accuracy, and it is simple to operate, safely and fast, structure is reliable, economy, whole device makes detachably and repeatedly With new way can be provided for the loading of single-beam static test in actual bridge machinery.

Specific embodiment
With reference to specific embodiment the charger for single-beam static test described in the utility model is done into One step is illustrated, but protection domain of the present utility model is not limited to this.
Embodiment 1
A kind of charger for single-beam static test, including box beam 1, leveling steel plate 2, hydraulic jack 3, concrete Cushion block 4, carrier bar 5, anchor beam 6, centre-hole jack 7, steel strand wires 8, P anchors 9, regular reinforcement 10, cushion cap 11 and sleeper 12;It is described 1 two bottom sides of box beam are supported by sleeper 12;, near 1 top surface span centre of box beam, which is upper and lower for 3 symmetrical placement of the hydraulic jack Face uses 2 levelling of leveling steel plate;Concrete pad 4 is located to be lowered between 1 top surface of plain plate 2 and box beam;The top of hydraulic jack 3 End is supported in the center of 5 bottom surface of carrier bar;5 upper surface both sides of carrier bar are provided with anchor beam 6;Punching is disposed with above anchor beam 6 Formula jack 7;Centre-hole jack 7 carries out one-end tension to 8 stretching end of steel strand wires, and carrier bar 5 puts more energy into form reaction beam;Steel is twisted 8 anchored end of line is fixed on the regular reinforcement 10 of 11 bottom of cushion cap by P anchors 9.
The steel strand wires 8 pass perpendicularly through carrier bar 5.The steel strand wires 8 are perpendicularly fixed at cushion cap 11.The pre-buried steel strand wires 8 quantity are determined according to the load tonnage that hydraulic jack 3 applies.8 anchored end of the steel strand wires is fixed on cushion cap 11 by P anchors 9 On bottom layer of the reinforcing steel 10, it is ensured that carrier bar 5 puts more energy into form counterforce device.The vertical load that 1 top surface of the box beam applies is directly by liquid Pressure jack 3 is completed, and the loading tonnage of hydraulic jack 3 depends on calculating load and being affected by 3 relative position of hydraulic jack, liquid Pressure 3 relative position of jack can be adjusted in real time.
