Problems solved by technology
[0002] With the development of the construction industry, the division of labor is more refined, and at the same time, the inspection is more scientific and rigorous. During the existing force column test, the force effector, force sensor and support platform are added to the force column to be tested. Load, the force sensor collects the pressure on the stressed column to be tested. Since the stressed column to be tested is large, it is easy to overturn, and it is easy to be skewed when loaded, which poses a safety hazard, and it is difficult to test the compressive bearing capacity of the eccentric compressed column

The invention relates to a pressure resistance detection device and method of an eccentric compression column. The pressure resistance detection device comprises a loading jack, a lower bearing plateis arranged below the loading jack, and an upper bearing plate is arranged above the lower bearing plate; the lower bearing plate and the upper bearing plate are each provided with an eccentric compression supporting base, a pressure sensor is arranged between the upper bearing plate and the eccentric compression supporting base corresponding to the upper bearing plate, and a supporting plate is arranged on the lower bearing plate; a row of vertical dial gauges are connected with the supporting plate at intervals, a supporting jack is arranged on the lower bearing plate, the eccentric compression column is arranged between the eccentric compression supporting bases, the supporting jack abuts against a column body of the eccentric compression column, and measuring ends of all the dial gauges abut against the outer side surfaces of the column body. The loading jack cooperates with the eccentric compression supporting bases, so that the eccentric compression column bear pressure reliably;meanwhile, since the supporting plate cooperates with the dial gauges, when the eccentric compression column is stressed, the dial gauges can accurately and reliably measure compression data of the eccentric compression column, and the compression bearing capacity of the eccentric compression column can be calculated in combination with formulas.
Description
technical field [0001] The invention relates to the technical field of pressure-resistant detection devices, in particular to a detection device and detection method for eccentric compression columns. Background technique [0002] With the development of the construction industry, the division of labor is more refined, and at the same time, the inspection is more scientific and rigorous. During the existing force column test, the force effector, force sensor and support platform are added to the force column to be tested. Load, the force sensor collects the pressure on the stressed column to be tested. Since the stressed column to be tested is large, it is easy to overturn, and it is easy to skew when loaded, which poses a safety hazard, and it is difficult to test the compressive bearing capacity of the eccentric compressed column. Contents of the invention [0003] The purpose of the present invention is to provide a detection device and detection method for the compress...
