A multifunctional portable adhesive anchor performance testing device

Abstract

The invention discloses a multifunctional portable bonding anchorage performance detection device which comprises an assembled rotary table, a clamp piece type assembled anchorage device, a displacement sensor, a frame assembly and four through steel threaded rods, wherein the upper ends of the steel threaded rods are connected with the assembled rotary table, and the lower ends of the steel threaded rods are connected with the frame assembly; the clamp piece type assembled anchorage device is arranged between the assembled rotary table and a part to be tested, the lower end of the clamp piece type assembled anchorage device is closely connected with the end of the part to be tested, and the upper end of the clamp piece type assembled anchorage device is closely connected with the assembled rotary table; one end of the displacement sensor is fixed on rib material of the part to be tested, and the other end of the displacement sensor passes through the frame assembly and is contacted with the part to be tested. The multifunctional portable bonding anchorage performance detection device is simple in structure, easy to be assembled and convenient to carry, can be used for detecting the bonding anchorage performance of a reinforcing steel bar (or a complex fiber rib) between monotonic load, repeated load or especially low frequency cyclic load and concrete substrate, and has the detection ways including center tensile compression, eccentric tensile compression, two-end relative tensile compression and the like, thus meeting the demands of scientific research or field test.

Description

technical field [0001] The invention belongs to the field of construction equipment, and relates to a bonding and anchoring performance detection device, in particular to a multifunctional casual-type bonding and anchoring performance detection device. Background technique [0002] Effective bonding between steel bars (or composite fiber bars) and concrete is a prerequisite for the normal operation of reinforced concrete structures. key issues. Existing test research, especially under the condition of repeated loading or low-cycle repeated loading, the commonly used hydraulic universal testing machine cannot or can only partially meet the test requirements, and most of them are carried out by using test equipment such as MTS electro-hydraulic servo testing machine Yes, but such large-scale equipment is expensive to purchase, and the environmental requirements of the test site are relatively harsh. Therefore, this largely limits the extent and depth of research in this field...
