Adjustable self-balancing wooden column long-term compression test device

Abstract

The invention discloses an adjustable long-term pressure test device for a self-balancing wooden column, which comprises at least three threaded rods parallel to each other, and the threaded rods are movably fitted with a first steel plate, a second steel plate, a third steel plate, a The fourth steel plate and the fifth steel plate; the threaded rod is located on the upper side of the first steel plate and is provided with an upper positioning nut; the threaded rod is located on the lower side of the fifth steel plate and is provided with a lower positioning nut; nut; a pressure sensor is set between the second steel plate and the third steel plate; a spring is set between the third steel plate and the fourth steel plate; a hydraulic oil cylinder is set between the fourth steel plate and the fifth steel plate; An upper knife hinge mechanism, a lower knife hinge mechanism is provided on the upper side of the second steel plate, and a wooden post installation space is left between the upper knife hinge mechanism and the lower knife hinge mechanism. The device solves the problem that it is difficult to exert long-term vertical pressure on a full-scale wooden column, and is easy to disassemble and install. It is specially used for long-term compression testing of wooden 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
