Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing of description and specific embodiment:

[0038] like figure 1 , figure 2 shown. A kind of one-way eccentric hinge support, comprising a base 5, the top of the base 5 is provided with a bearing plate 1, the lower surface of the bearing plate 1 is fixedly provided with a connecting plate I2, and the upper surface of the base 5 A connecting plate II3 is fixedly arranged on the upper part, the lower surface of the bearing plate 1 is welded with the connecting plate I2 to form a whole, and the upper surface of the bearing plate 1 is in contact with the end of the test member tightly. The upper surface of the base 5 is welded with the connecting plate II3 to form a whole. The whole formed by the bearing plate 1 and the connecting plate I2 is connected with the integral formed by the base 5 and the connecting plate II3 through the pin shaft 4, and the connecting plate I2 and the...

Abstract

The invention discloses a one-way eccentric hinge support and a use method thereof, and belongs to the field of constructional engineering. The one-way eccentric hinge support comprises a base, a load-bearing plate is arranged above the base, first connecting plates are fixedly arranged on the lower surface of the load-bearing plate, second connecting plates are fixedly arranged on the upper surface of the base, and the first connecting plates are hinged to the second connecting plates in a relatively rotatable mode; at least two sets of sliding baffles are arranged on the load-bearing plate, the sliding baffles slide along the load-bearing plate, therefore, the sliding baffles clamp a test component, and the test eccentricity of the test component is adjusted. The one-way eccentric hinge support is easy to machine and convenient to install and use, and all parts are easy to store after being disassembled. The support is suitable for tests of axial compression, axial tension, eccentric compression, eccentric tension and the like, and an ideal use effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a one-way eccentric hinge support and its application method. Background technique [0002] In the scientific research in the field of construction engineering, experimental methods are often used to study the mechanical properties of components. In order to eliminate the influence of the testing machine on the constraints at both ends of the component, the test component often uses a hinged support. However, the existing knife-edge bearings and spherical joint bearings can only be used for axial compression tests of components, and cannot be used for eccentric compression and tension tests of components. [0003] The existing knife-edge bearings are widely used, but under high pressure, high stress concentration occurs at the knife-edge, which is easy to cause wear to the alveolar plate; and when the component reaches a critical state, the sliding of the compon...
