Description

A kind of single-beam static test loading system
Technical field
This utility model belongs to Bridge Inspection field, it particularly relates to arrive a kind of single-beam static test loading system System.
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 little single-beam static load examination Test loading system.
A kind of single-beam static test loading system described in the utility model, the loading system includes box beam 1, leveling steel Plate 2, hydraulic jack 3, concrete pad 4, carrier bar 5, anchor beam 6, anchor plate 7, P anchors 8, steel strand wires 9, structural steel frame of putting more energy into 10th, centre-hole jack 11, pre-embedded steel slab 12, cushion cap 13 and sleeper 14;The two bottom sides of box beam 1 are supported by sleeper 14;Hydraulic pressure thousand Near the top surface span centre of box beam 1, its above and below uses the levelling of leveling steel plate 2 to 3 symmetrical placements of jin top;Concrete pad 4 is located at Lower between plain plate 2 and the top surface of box beam 1;The apical support of hydraulic jack 3 is in the center of the bottom surface of carrier bar 5;5 liang of carrier bar Side is provided with anchor beam 6;Anchor plate 7 is respectively and fixedly provided with anchor beam 6;The anchored end of steel strand wires 9 is fixed on anchor plate 7 by P anchors 8, its Stretching end carries out one-end tension using positioned at the centre-hole jack 11 put more energy in structural steel frame 10;Put more energy into structural steel frame 10 with hold Pre-embedded steel slab 12 on platform 13 is welded.
A kind of single-beam static test loading system described in the utility model, the stretching end of the steel strand wires 9 is also secured to hold On platform 13.
A kind of single-beam static test loading system described in the utility model, the steel strand wires 9 are vertical with carrier bar 5.
Compared with prior art, single-beam static test loading system described in the utility model on cushion cap by arranging steel Anchored end is set on twisted wire stretching end, anchor beam, the counteracting force of box beam static load is directly undertaken by cushion cap, list can be significantly improved Piece box beam static test efficiency and performance accuracy, and it is simple to operate, safely and fast, structure is reliable, economy, whole device can Dismounting is reused, and can provide new method for the loading of single-beam static test in actual bridge machinery.
