Specific embodiment
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
Embodiment
Referring to FIG. 1 to FIG. 3, the present embodiment includes: including the first fixed charge method end plate 1, the second fixed charge method end plate 3, sliding panel 2, four Root guide rod 4,5, the first test member 7, the second test member 15, concrete component 6, it is fixed that the sliding panel 2 is located at first Between end plate 1 and the second fixed charge method end plate 3, and the first fixed charge method end plate 1, sliding panel 2 and the second fixed charge method end plate 3 are placed in parallel;
First test member 7 and the second test member 15 are FRP component;
First test member 7, the second test member 15 are each passed through the both ends of the second fixed charge method end plate 3 and sliding panel 2, And it is fixed on the second fixed charge method end plate 3;
Specifically, second fixed charge method end plate 3 and sliding panel 2 all offer strip at away from left and right edges 57.5mm and open Mouthful, first test member 7, the second test member 15 are open by strip across the second fixed charge method end plate 3 and sliding respectively Plate 2, and it is fixed on the second fixed charge method end plate 3;
The one of embodiment of the present embodiment is that strip opening is that length is 100mm, and width is the strip of 5mm Opening;
The both ends of four guide rods 4,5 are fixedly connected with the first fixed charge method end plate 1, the second fixed charge method end plate 3 respectively, and four Guide rod 4,5 is each passed through sliding panel 2, and four guide pipes 4,5 are symmetrical arranged;
First fixed charge method end plate 1, the second fixed charge method end plate 3 are identical with the size dimension of sliding panel 2, and the first fixed charge method end plate 1, it is 20mm circular hole in order to four cylindrical guide bars that four angles of the second fixed charge method end plate 3 and sliding panel 2, which all offer diameter, Pass through.
The concrete component 6 is arranged between the first test member 7 and the second test member 15;The concrete component 6 are placed on underlying two guide rods by concrete support plate 11, and the smooth purpose in 11 surface of concrete support plate It is to reduce concrete and the friction between it.
Pressure sensor 12 and jack 10 are equipped between the concrete component 6 and the second fixed charge method end plate 3;The pressure Sensor 12 and jack 10, which are arranged on the central axes of concrete component 6, makes concrete axial compression, and otherwise eccentric compression will Weaken the bearing capacity of test member (FRP) under causing on test member (FRP) along unbalance stress.
The sliding panel 2 is equipped with electromechanical dial gauge pedestal 9, and electromechanical dial gauge 8 passes through electromechanical dial gauge pedestal 9 and is fixed on On sliding panel, first test member 7 and the second test member 15 any of end be equipped with locating plate, electromechanical percentage Table 8 with locating plate is unstressed contacts, when sliding between FRP and concrete, electromechanical dial gauge can pass through TDS530 essence True measurement.
Specific work process: red, green, black, the white line on high-precision pressure sensor 10 are successively connect in TDS-530 data On Acquisition Instrument, the then oil pump of jack 12.By giving jack 12 applied force by pressure oil pump, 12 one end of jack is ined succession second solid Fixed end plate 3, the other end are ined succession pressure sensor 10, and power is shown on TDS-530 data collecting instrument while will by pressure sensor Power is transmitted to sliding panel 2 and is transmitted to concrete component 6 again.First and second test member (FRP) is cast in the two sides of concrete component 6, Its curing time is one week, and the spacing in 6 outside of test member (FRP) and concrete component is 1 centimeter.When concrete component 6 by When power, since test member (FRP) is in succession on the first fixed charge method end plate 1, and be fixed with anchor with intermediate plate 13 and bolt 14, so surveying Examination component (FRP) will limit concrete component and move outward.With the continuous applied force of oil pump, TDS-530 data collecting instrument Moment shows the variation of power, and test member (FRP) can generate stretching and generate sliding with concrete.Locating plate is mounted in survey Try component (FRP) stretch out concrete component when at, start with electromechanics dial gauge be it is unstressed contact, when concrete component stress to When outer Slideslip, test member (FRP) will limit its sliding, and when power increases to certain degree, test member (FRP) can be with Concrete generates sliding, and electromechanical dial gauge just can measure its slippage at this time.
Conventional method is placed in jack among two concrete test blocks, Manual pressurizing jack, then by very heavy Oil pressure gauge on top is obtained to concrete pressure applied, and precision is not high enough.For this device, TDS- is increased 530 data collecting instruments and pressure sensor, TDS-530 data collecting instrument measurement range can achieve ± 640000 microstrains, often The measurement point measured can achieve at 1000 points within 0.4 second, substantially increase experimental precision and efficiency.
