Adjustable device for testing self-balancing long-term stressed wood columns

Abstract

The invention discloses an adjustable device for testing self-balancing long-term stressed wood columns. The device comprises at least three parallel threaded rods, wherein the threaded rods are movably sleeved by a first steel plate, a second steel plate, a third steel plate, a fourth steel plate and a fifth steel plate from top to bottom in sequence; the upper side of the first steel plate on the threaded rods is provided with upper positioning bolts; the lower side of the fifth steel plate on the threaded rods is provided with lower positioning bolts; the lower side of the fourth steel plate on the threaded rods is provided with locking bolts; a pressure sensor is arranged between the second steel plate and the third steel plate; a spring is arranged between the third steel plate and the fourth steel plate; a hydraulic oil cylinder is arranged between the fourth steel plate and the fifth steel plate; the lower side of the first steel plate is provided with an upper cutter hinge mechanism; the upper side of the second steel plate is provided with a lower cutter hinge mechanism; and a wood-column mounting space is left between the upper cutter hinge mechanism and the lower cutter hinge mechanism. The device disclosed by the invention solves the problem that the vertical pressure can not be applied to the full-size wood columns for a long time, and the device is easy to assemble and disassemble and is specially used for testing the long-term stressed wood columns.

Description

technical field [0001] The invention relates to a testing device, in particular to a wooden column vertical pressure loading testing device. Background technique [0002] Many design theories in civil engineering come from the statistical analysis of a large number of experiments. Whether it is the research and development of new structural systems, the design and construction of complex structures, or the performance testing of components in existing buildings, it is necessary to carry out experimental research on structures and components. In particular, the experimental research on the mechanical properties of important structural components such as columns and walls subjected to vertical and lateral forces for a long time is particularly important for the reliability of the structure. [0003] In the test of wooden structural members, in order to obtain more accurate test results, it is necessary to test the full-scale specimens. Generally, the vertical loading device i...

Problems solved by technology

[0003] In the test of wooden structural members, in order to obtain more accurate test results, it is necessary to test the full-scale specimens. Generally, the vertical loading device in the laboratory cannot meet the long-term pressure test requirements of full-scale wooden columns, resulting in the design of wooden columns. There is a certain error in the calculation parameters
