Abstract

The invention discloses an FRP (fiber reinforced plastic) adhesive strength integrated tester; a sliding plate is positioned between a first fixing end plate and a second fixing end plate, the first fixing end plate, the sliding plate and the second fixing end plate are arranged in parallel, a first test member and a second test member are passed through the two ends of the second fixing end plate and sliding plate respectively and are fixed to the second fixing end plate, two ends of four guide rods are fixedly connected to the first fixing end plate and the second fixing end plate respectively, the four guide rods are passed through the sliding plate respectively, four guide tubes are arranged in symmetry, a concrete member is arranged between the first test member and the second test member, a pressure sensor and a jack are arranged between the concrete member and the second fixing end plate, and an electromechanical dial gage is arranged on the sliding plate. With an oil pump and a jack used to provide pressure, and TDS-530 data acquirer, the pressure sensor and the electromechanical dial gage used to measure adhesive strength and slip between FRP and concrete, the integrated multifunctional tester is achieved.

Description

technical field [0001] The invention belongs to the technical field of strength and displacement testing, and relates to a tester, in particular to a comprehensive tester for bonding strength and slip of FRP-concrete interface. Background technique [0002] The strength and displacement tester is a kind of electromechanical test instrument that is generally required in the civil engineering industry. It has the advantages of high precision, high stability and high efficiency. At present, fiber-reinforced concrete technology has been widely used at home and abroad. The key to this technology is the bonding effect of the FRP-concrete interface. However, the test method for the bonding strength of the FRP-concrete interface has always been difficult, especially because there is no portable on-site test equipment. Based on this problem, a simple and convenient FRP adhesive strength comprehensive tester has become a new market demand. At present, only some research institutes h...
