Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.
Referring to figs. 1 to Fig. 3
To the device of the two-way Shi Hanzhang of CFRP plate in a kind of static trial, comprise the first anchor block 1 for being fixedly connected with ground, described first anchor block is connected with horizontal I-beam 2, the length that the length of described horizontal I-beam tests beam 7 by the rectangle of simulated implementation determines, the other end of horizontal I-beam is connected with the second anchor block 4 through a telescoping mechanism 3, is positioned on the first anchor block and the second anchor block and is also respectively arranged with for the ground tackle 6 of anchoring CFRP plate 5 on the first anchor block and the second anchor block beside.
In the present embodiment, described CFRP plate one end is anchored on through ground tackle in the beside of the first anchor block, the other end of CFRP plate is anchored on the surface of the second anchor block side corresponding to the first anchor block through ground tackle, and two beside being positioned at the first anchor block and the second anchor block can install CFRP plate respectively.
In the present embodiment, described ground tackle comprises the Qian type frid 61 for being enclosed within the first anchor block, the second anchor block or rectangle experiment beam periphery, the biside plate 62 of described Qian type frid being laid with respectively the expansion anchor 63 for penetrating in the first anchor block 1, second anchor block 2 or rectangle experiment beam, on the downside of the base plate 64 of Qian type frid, being connected with panel 66 through some high-strength bolts 65.Described panel 66 is respectively arranged with corresponding texture with on the surface of base plate 64, so that effective fixation of C FRP plate.
In the present embodiment, described telescoping mechanism is lifting jack, and lifting jack will have enough ranges and degree of accuracy, just can meet the requirement of experiment, and expansion link end one junction steel plate 8 of described lifting jack is connected with the second anchor block.
In the present embodiment, between the expansion link end of described lifting jack and junction steel plate, be also provided with pressure transducer, to control the prestress applied.
In the present embodiment, described first anchor block and the second anchor block to be arranged on same axial line and to make by concrete.Can by contrasting with stretching rope during installation, the second anchor block can movement arbitrarily on this axial line again; Distance between first anchor block and the second anchor block is greater than the rectangle experiment beam length of simulated experiment, facilitates CFRP plate to be anchored on rectangular beam.
The using method of this device:
