[0001] The present invention belongs to the technical field of building engineering detection, and particularly relates to a mechanical testing machine for building isolation rubber bearings. Background Art
[0002] The mechanical tests of building isolation rubber bearings mainly include vertical compression, vertical tension, shear compression, shear tension, and compression creep. Among them, compression creep is to test the situation where the deformation of the rubber bearing changes with time under a certain temperature and pressure. The existing testing machines are compression-tension testing machines and shear testing machines, which cannot achieve multi-functional mechanical tests. Summary of the Invention
[0003] The purpose of the present invention is to provide a comprehensive testing machine for building isolation rubber bearings, which can achieve more mechanical test functions on one device.
[0004] A comprehensive testing machine for building isolation rubber bearings of the present invention includes a cross beam, a longitudinal workbench, a vertical oil cylinder, a load sensor A, a transverse workbench A, a transverse oil cylinder A, a load sensor B, a high-temperature box, a base, a transverse workbench B, a transverse oil cylinder B, and a load sensor C. The cross beam is fixed to the foundation through columns. The longitudinal workbench includes an upper pressing frame, a lower pressing frame, and guide columns connected between the upper pressing frame and the lower pressing frame. A force transmission pedestal is provided on the upper part of the lower pressing frame. The guide columns are preferably four, and the guide columns are slidably connected to the cross beam up and down. The vertical oil cylinder is used to push the longitudinal workbench, and the vertical oil cylinder is installed on the upper part of the cross beam. The head of the piston rod of the vertical oil cylinder is connected to the bottom surface of the upper pressing frame through the load sensor A. The transverse workbench A is slidably installed on the cross beam left and right. A left force transmission seat and a right force transmission seat are provided on the bottom surface of the transverse workbench A. The transverse oil cylinder A is used to push the transverse workbench A, and the head of the piston rod of the transverse oil cylinder A is connected to the transverse workbench A through the load sensor B. The high-temperature box is installed below the transverse workbench A, and the high-temperature box is used for heating the sample building isolation rubber bearing. The base is located below the longitudinal workbench and is fixed to the foundation. The transverse workbench B is slidably installed on the base left and right. The transverse oil cylinder B is used to push the transverse workbench B, and the head of the piston rod of the transverse oil cylinder B is connected to the transverse workbench B through the load sensor C. A displacement sensor A and a displacement sensor B are installed on the cross beam, which are respectively used to detect the displacement of the longitudinal workbench and the transverse workbench A. A displacement sensor C is installed on the base, which is used to detect the displacement of the transverse workbench B.
[0005] Further, the high-temperature box has a side door. The right force transmission seat penetrates the top of the high-temperature box. A bottom hole is provided at the bottom of the high-temperature box. When the high-temperature box is directly above the lower pressing frame, the force transmission pedestal on the lower pressing frame can penetrate the bottom hole.
[0006] The comprehensive testing machine for building isolation rubber bearings of the present invention works as follows. During the vertical compression test, the horizontal oil cylinder A pushes the transverse moving workbench A to move until the left transfer seat is aligned with the transfer seat on the lower pressing frame. The building isolation rubber bearing is installed on the transfer seat. The vertical oil cylinder pushes the longitudinal workbench to move upward, pressing the building isolation rubber bearing against the left transfer seat for the vertical compression test. The load sensor A measures the pressure value, and the displacement sensor A measures the compression amount. During the shear compression test, the building isolation rubber bearing is pressed against the left transfer seat and the test pressure is applied according to the above method. The horizontal oil cylinder A pushes the transverse moving workbench A to move, and the top of the building isolation rubber bearing moves with the transverse moving workbench A for shear deformation. The load sensor B measures the shear force, and the displacement sensor B measures the horizontal displacement amount.
[0007] During the vertical tension test, the building isolation rubber bearing is connected between the lower pressing frame and the transverse moving workbench B. The vertical oil cylinder pushes the longitudinal workbench to move upward for the tension test of the building isolation rubber bearing. The load sensor A measures the pressure value, and the displacement sensor A measures the tension amount. During the shear tension test, the building isolation rubber bearing is connected between the lower pressing frame and the transverse moving workbench B according to the above method. The horizontal oil cylinder B pushes the transverse moving workbench B to move, and the bottom of the building isolation rubber bearing moves with the transverse moving workbench B for shear deformation. The load sensor C measures the shear force, and the displacement sensor C measures the horizontal displacement amount.
[0008] During the compression creep test, the building isolation rubber bearing is placed in the high-temperature box, and the center of the rubber bearing is aligned with the center of the right transfer seat. The horizontal oil cylinder A pushes the transverse moving workbench A to move until the right transfer seat is aligned with the transfer seat on the lower pressing frame. The high-temperature box is heated according to the test temperature. The vertical oil cylinder pushes the longitudinal workbench to move upward, pressing the building isolation rubber bearing against the right transfer seat and applying pressure according to the test pressure. The load sensor A measures the pressure value, and the displacement sensor A measures the compression amount according to the test time requirement. The compression creep test detects the change of the deformation amount of the building isolation rubber bearing with time under a certain temperature and pressure.
[0009] An integrated testing machine for building isolation rubber bearings of the present invention includes a cross beam, a longitudinal workbench, a vertical oil cylinder, a load sensor A, a transverse workbench A, a transverse oil cylinder A, a high-temperature chamber, a base, a transverse workbench B, and a transverse oil cylinder B. The longitudinal workbench includes an upper pressing frame, a lower pressing frame, and guide columns connected between the upper pressing frame and the lower pressing frame. During vertical compression testing, the vertical oil cylinder pushes upward a rubber bearing located above the lower pressing frame to compress it on the transverse workbench A. During vertical tensile testing, the vertical oil cylinder pushes upward a rubber bearing located below the lower pressing frame to stretch it upward. The moving direction of the vertical oil cylinder is the same, which is beneficial to the operation of the load sensor A and the oil cylinder. The high-temperature chamber is installed below the transverse workbench A, and the high-temperature chamber and the test sample are moved to the lower pressing frame by the movement of the transverse workbench A. Combining with the upward compression of the longitudinal workbench, a creep test is achieved. Using the transverse workbench A to horizontally push the top of the rubber bearing and combining with the upward compression of the longitudinal workbench, a shear compression test is achieved; using the transverse workbench B to horizontally push the bottom of the rubber bearing and combining with the upward stretching of the longitudinal workbench, a shear tensile test is achieved. Many mechanical test functions are realized on one device. BRIEF DESCRIPTION OF THE DRAWINGS
