Embodiment 1

[0035] Such as figure 1 and figure 2Shown is a specific embodiment of the fiber-reinforced composite material-reinforced concrete bonding performance test device provided by the present invention, including a mounting bracket 1 and two auxiliary plates 9 installed in parallel on the connecting plate in turn, and the two auxiliary plates 9 A force-applying track 10 is installed on the top to limit the movement path of the impact member 15 .

[0036] The movable platform 2, the fixed platform 3 and the baffle plate 7 are successively installed on the mounting bracket 1 from bottom to top, the movable platform 2, the fixed platform 3 and the baffle plate 7 are horizontally arranged and parallel to each other, and the movable platform 2 extends outwards with an impact portion, and the The force track 10 is a bent track with a height difference in the vertical direction, and the side wall of the inlet end is provided with an opening, and the opening is provided with a scale, and ...

Embodiment 2

[0040] A method for testing the bond performance of fiber reinforced composite reinforced concrete, comprising the following steps:

[0041] The first test piece 12 and the second test piece 13 are connected through the fiber reinforced composite material sheet 14, the first test piece 12 is loaded in the first storage space, the second test piece 13 is loaded in the second storage space, and balance Balance weights are loaded into the box 5, so that the movable platform 2 and the first test block 12 maintain a balanced state with the balance box 5 and the balance weights. The first test block 12 is clamped on the fixed platform 3 by adjusting the first clamping screw and the second test block 13 is clamped on the movable platform 2 by adjusting the second clamping screw.

[0042] The impact part 15 falls from the force application track 10 and hits the impact part of the movable platform 2, so that the interface between the fiber reinforced composite material sheet 14 and the...

Abstract

The invention relates to the technical field of mechanical property test devices, in particular to a device and a method for testing the adhesive property of fiber reinforced composite reinforced concrete. The device comprises an installation support and a balance box, a movable platform and a fixed platform are sequentially installed on the installation support from bottom to top, the movable platform extends outwards to form an impact part, and a first storage space used for storing a first test block and a second storage space used for storing a second test block are formed in the movable platform and the fixed platform respectively; the balance box is connected with the movable platform through a connecting piece, a balance weight is arranged in the balance box, and the connecting piece bypasses the top of the installation support, so that the balance box and the movable platform are located on the two sides of the installation support. Accurate energy consumed by fracture of a fiber reinforced composite material sheet can be obtained by measuring the difference between the energy of an impact piece impacting the movable platform and the energy of the movable platform, the first test block and the impact piece after the connection interface is fractured.

Description

technical field [0001] The invention relates to the technical field of mechanical performance testing devices, in particular to a device and method for testing the bond performance of fiber-reinforced composite material-reinforced concrete. Background technique [0002] Nowadays, Fiber Reinforced Polymer (FRP) has been widely used in the field of seismic reinforcement of concrete structures due to its advantages of light weight, high strength and easy construction. When the FRP-strengthened concrete structure is stressed together, the fracture surface of the structure is usually the contact interface between FRP and concrete, so it is very important to study the strength of the FRP-concrete interface. In practical applications, FRP reinforced concrete is often subjected to dynamic loads such as earthquakes, explosions, and impacts. Under dynamic impacts, FRP reinforced concrete will be damaged to varying degrees, and debonding is one of the main failure modes of FRP reinforc...
