Abstract
The utility model discloses a steel stranded wire anchoring test instrument, which comprises a bracket, wherein the bracket comprises a front end plate and a rear end plate as well as a supporting post which is arranged between the front end plate and the rear end plate, the front end plate is provided with an anchoring piece mounting bracket, a pressure sensor, a jacking force device and the anchoring piece mounting bracket are fixed on the side of the rear end plate which is away from the front end plate, one end of the rear end plate which is away from the front end plate is provided with a test jacking plate, and a jacking post is arranged between the rear end plate and the test jacking plate. When the anchoring test instrument tests the pressure sensor, only a standard pressure sensor is arranged between the jacking force device and the test jacking plate, the jacking force device is started, and the reading of the pressure sensor of the steel stranded wire anchoring test instrument is compared with that of the standard pressure sensor, so an error value of the pressure sensor can be judged. The steel stranded wire anchoring test instrument has the characteristics of convenience in operation and accurate test data.
Description
Technical field
The utility model relates to a kind of road test instrument, the steel strand wires anchoring test instrument of more specifically saying so, dependent territory worker's test apparatus technical field.
Background technology
In bridge, large scale prefabricated plate such as overhead, generally be provided with steel strand wires, steel strand wires pass prefabricated board two ends, and two ends are fixed by anchoring piece.Existing anchoring piece comprises overcoat and sandwich, and outer casing inner wall and sandwich outer wall have the inclined-plane that is complementary, and sandwich is subjected to the pulling force of steel strand wires, makes sandwich be subjected to the extruding force of overcoat, thereby clamps the steel strand wires in the sandwich.Because steel strand wires are used for strengthening the intensity of bridge, large scale prefabricated plate such as overhead, its quality is directly connected to the safety of infrastructure, therefore, need carry out the anchoring test to steel strand wires.
Existing steel strand wires anchoring test instrument is generally horizontal, has support, support comprises front end-plate, end plate, and the tappet between front end-plate, end plate, front end-plate is provided with the anchoring piece erecting frame, end plate is provided with the cubing erecting frame, fixation pressure sensor, top power device and anchoring piece erecting frame successively on the cubing erecting frame.Do anchoring when test, the anchoring piece of steel strand wires two ends is being placed on two anchoring piece erecting frames of test instrument, can start top power device, reading the data of pressure transducer.The steel strand wires anchoring test instrument of said structure has easy to use, advantages of simple structure and simple, but the main problem that exists is: during the effect pressure transducer, pressure transducer need be removed, deliver to the unit of calibrating then, the calibrating unit on end carries out effect to pressure transducer when calibrating, unhandy problem when therefore having effect on the one hand, on the other hand, pressure transducer is for erectting during effect, different with its real duty, therefore, the data that also exist the pressure transducer effect to be have the problem of deviation.
The utility model content
At the problems referred to above, easy to operate when the problem that the utility model quasi-solution is determined provides a kind of effect pressure transducer, and effect data steel strand wires anchoring accurately test instrument.
For addressing the above problem, the utility model has adopted following technical scheme: a kind of steel strand wires anchoring test instrument, it comprises support, described support comprises front end-plate, end plate, and the tappet between front end-plate, end plate, described front end-plate is provided with the anchoring piece erecting frame, described end plate is away from a side fixation pressure sensor, top power device and the anchoring piece erecting frame of front end-plate, described end plate is provided with the effect top board at the end away from front end-plate, is provided with fore-set between described end plate and the effect top board.
Described top power device can be the electric hydaulic lifting jack.
Adopted said structure,, be provided with fore-set between described end plate and the effect top board owing to be provided with the effect top board away from an end of front end-plate at end plate.Make the anchoring test instrument like this when the effect pressure transducer, only need between top power device and effect top board, to put into standard pressure transducer, open top power device, the pressure transducer of comparative steel twisted wire anchoring test instrument and the reading between the standard pressure transducer, the i.e. error amount of decidable pressure transducer.Therefore, steel strand wires anchoring test instrument of the present utility model has easy to operate, and effect data characteristic of accurate.
Description of drawings
Structural representation when Fig. 1 is the test of the utility model steel strand wires anchoring test instrument;
Structural representation when Fig. 2 is steel strand wires anchoring test instrument effect pressure transducer.
Among the figure: 1-support, 2-tappet, 3-front end-plate, 4-end plate, 5-pressure transducer, 6-top power device, 7-anchoring piece erecting frame, 8-effect top board, 9-standard pressure transducer, 10-fore-set, 11-steel strand wires.
Embodiment
As shown in Figure 1 and Figure 2, steel strand wires anchoring test instrument of the present utility model, it comprises support 1, described support comprises front end-plate 3, end plate 4, and the tappet 2 between front end-plate 3, end plate 4, described front end-plate 3 is provided with anchoring piece erecting frame 7, and described end plate 4 is away from a side fixation pressure sensor 5, top power device 6 and the anchoring piece erecting frame 7 of front end-plate 3, and described top power device 6 generally adopts the electric hydaulic lifting jack.Therefore the similar of the horizontal steel strand wires anchoring test instrument of said structure and prior art, is no longer launched to describe.
The characteristics of steel strand wires anchoring test instrument of the present utility model are: described end plate 4 is provided with effect top board 8 at the end away from front end-plate 3, is provided with fore-set 10 between described end plate 4 and the effect top board 8, and the quantity of fore-set 10 is generally four.
Referring to Fig. 1, steel strand wires anchoring test instrument of the present utility model at the trial, fixing steel strand wires 11 between the anchoring piece erecting frame 7 of the anchoring piece erecting frame 7 of front end-plate 3 and end plate 4 start top power device 6, pressure transducer 5 is the pulling force that steel strand wires 11 are subjected to, just anchoring strength.
Referring to Fig. 2, steel strand wires anchoring test instrument of the present utility model is put into standard pressure transducer 9 between top power device 6 and effect top board 8 when the effect pressure transducer.Open top power device then, the pressure transducer of comparative steel twisted wire anchoring test instrument and the reading between the standard pressure transducer, the i.e. error amount of decidable pressure transducer.
