Auxiliary device for mechanical loading test of right-angle component and test device

Abstract

The invention discloses an auxiliary device for a mechanical loading test of a right-angle component and a test device, and relates to the technical field of reinforced concrete structure mechanical property testing. The auxiliary device comprises a substrate, at least one longitudinal rib plate, at least one transverse rib plate and a right-angle plate, wherein the longitudinal rib plate, the transverse rib plate and the right-angle plate are located on one side of the substrate. The longitudinal rib plate is arranged in the length direction of the substrate and perpendicular to the substrate. The transverse rib plate is arranged in the width direction of the substrate and perpendicular to the substrate. The opening of the right-angle plate is arranged back to the substrate, and the corner edges of the right-angle plate are arranged in the width direction of the substrate. One end of the longitudinal rib plate and one end of the transverse rib plate are connected with the substrate, and the other ends are connected with the right-angle plate. The auxiliary device can be used for carrying out the mechanical loading test on the right-angle reinforced concrete component, and the technical defects of an existing loading auxiliary device for the right-angle reinforced concrete component are overcome.

Description

technical field [0001] The invention relates to the technical field of mechanical performance testing of reinforced concrete structures, and more particularly relates to an auxiliary device and a testing device for mechanical loading tests of right-angled members. Background technique [0002] Reinforced concrete structure is the most widely used structural form of structures since the 20th century. From high-rise buildings to subsea tunnels, it can be seen in almost all important human structures. Among the common structural components, regular-shaped beams, slabs and columns are the most important structural components. In order to improve applicability, almost all mechanical performance testing machines adopt the direct pull or direct compression loading method. The disadvantages of the existing mechanical performance testing machines for direct tension and direct compression loading are also very obvious. When encountering irregular specimens, especially specimens whose ...

Problems solved by technology

In addition, the device arranges steel plates in a large area, which consumes a lot of steel; different sizes of test pieces need to drill different bolt holes on the steel plates, and the reusability performance is not good.
