The device comprises a pressure jack, a pressure sensor, a pressure bearing, a fluted disc, a rolling shaft support, a tension jack, a tension sensor and the like, wherein a counterforce pier is mounted on the ground; the pressure jack is mounted on the counterforce pier at one side; the pressure sensor and the pressure bearing are mounted at the front end of the pressure jack; the tension sensor is mounted at the top end of the tension jack and is connected with a steel wire rope wound on the fluted disc; and the rolling shaft support and a pedestal are mounted below the fluted disc. During the testing, the concrete-filled steel tube column is mounted on the counterforce pier; the other end of the concrete-filled steel tube column is mounted on the fluted disc; the torque is provided by the tension jack; the axial pressured is provided by the pressure jack; and loading values are collected by the two sensors. The device disclosed by the utility model has the characteristics of being simple in whole structure, convenient to use, recyclable and the like.
Description
Technical field
The utility model relates to civil engineering work component test technical field, and it is that a kind of steel core concrete column is pressed torsional test charger in definite saying.
Background technology
In civil engineering work, when the wind-engagings such as concrete-filled steel tubular frame side column, power transmission tower frame and offshore oil production platform leg post and seismic loading, just likely there is pressing the stress of turning round.It is less that at present Study on Steel pipe concrete column is pressed the test of turning round, and main cause is that charger is difficult to realize, and friction force is larger when axle pressure applies and between steel core concrete column, and impact is rotated; When moment of torsion applies, Changing Pattern is non-constant, can only be similar to value; Test findings and finite element analysis result gap are larger, can not effectively instruct engineering practice.
Summary of the invention
The purpose of this utility model is exactly to solve above-mentioned experiment loading unit to be difficult to the problem realizing, provide a kind of one-piece construction simple, easy to assembly, can be recycled, particularly test figure accurately steel core concrete column press torsional test charger.The purpose of this utility model is achieved in that steel core concrete column pressure torsional test charger comprises pressure lifting jack, pressure transducer, pressure bearing, groove disk, wire rope, pull bar, screw rod, web joint, counter-force pier, connector, roller support, pedestal, pulling force lifting jack and pulling force sensor.It is characterized in that: counter-force pier is installed on the ground, pull bar passes from four jiaos of counter-force pier, two counter-force piers are linked together, steel core concrete column one end is connected with web joint, and be fixed on counter-force pier by screw rod, the other end is connected with groove disk, pressure lifting jack is arranged on the counter-force pier of opposite side, the front end of pressure lifting jack is equipped with pressure transducer and pressure bearing, pulling force lifting jack is fixed on the ground under groove disk one side, pulling force sensor is equipped with on the top of pulling force lifting jack, pulling force sensor is connected with the wire rope being wrapped on groove circle by connector, under groove disk, roller support is housed, roller support is connected on ground by pedestal.
The utility model has the advantages that: solved press in torsional test in the past when pressure applies, affect that steel core concrete column rotates and process of the test in the inconstant two large problems of torque change rule, adopt pressure torsional test result and the finite element analysis result of steel core concrete column after the utility model to meet well, the feature such as that while the utility model also has is easy to assembly, can be recycled.

Embodiment
embodiment 1:
The spacing needing according to test is installed two counter-force piers 10 on the ground, and pull bar 6 passes from four jiaos of counter-force pier 10, and locking, two counter-force piers 10 is linked together, to increase the ability of its opposing horizontal reacting force.Pressure lifting jack 1 is arranged on the counter-force pier 10 of a side, the front end of pressure lifting jack 1 is equipped with pressure transducer 2 and pressure bearing 3, applying the pulling force lifting jack 14 that moment of torsion uses is arranged between counter-force pier 10, pulling force sensor 15 is equipped with on the top of pulling force lifting jack 14, pulling force sensor 15 is connected with the wire rope 5 being wrapped on groove disk 4 by connector 11, the pedestal 13 that roller support 12 is installed be above arranged on groove disk 4 below, in order to brace groove disk 4.While testing, one end of steel core concrete column 9 is arranged on the counter-force pier 10 of a side by web joint 8 and bolt 7, the other end of steel core concrete column 9 is installed groove disk 4, steel core concrete column 9, groove disk 4 and pressure lifting jack 1 should be coaxial, the height that is supported on groove disk 4 roller support 12 below should be adjustable, to guarantee steel core concrete column 9, groove disk 4 and pressure lifting jack 1 are coaxial, the axle pressure being applied on steel core concrete column 9 is provided by pressure lifting jack 1, by pressure transducer and pressure bearing, pass to steel core concrete column 9, in the time of pressure bearing transmission of pressure, can guarantee that steel core concrete column 9 freely rotates, the moment of torsion being applied on steel core concrete column 9 passes through pulling force sensor 15 by pulling force lifting jack 14, the groove disk 4 that connector 11 and wire rope 5 tractives are fixed on steel core concrete column 9 ends provides, consequent vertical force is offset by roller support 12, guarantee that in whole loading procedure, torque change rule is constant, roller support 12 can guarantee that steel core concrete column 9 freely rotates simultaneously.Drag load numerical value is gathered by pulling force sensor 15, and compressive load numerical value is gathered by pressure transducer 2, finally by crossing, calculates experimental data.
