The invention discloses a lever horizontal pull type concrete creep and elastic modulus test device. The upper end of the left upright column is movably connected with the lever through the first fulcrum, and the lever is connected with the first pull rod, the first pull rod and the second pull rod, and the second pull rod perpendicular to the third tie rod, a second fulcrum is provided at the connection point between the second tie rod and the third tie rod, the second tie rod and the third tie rod can rotate around the second fulcrum, the other end of the third tie rod is fixedly connected to one end of the fourth tie rod and The third tie rod and the fourth tie rod are perpendicular to each other, the other end of the fourth tie rod is connected to one end of the sensor, the other end of the sensor is connected to one end of the concrete specimen through a ball strand, the other end of the concrete specimen is connected to the right column, and the two ends of the sensor are horizontal and supported by the hanging angle , the hanging angle stands on the beam, the concrete specimen is placed horizontally on the beam, the beam is horizontal and both ends are installed on the left column and the right column, the bottom of the left column and the right column are connected by the bottom beam, and the head of the lever is equipped with a hanging bar . The invention has the beneficial effect of simple structure.
Description
technical field [0001] The invention belongs to the technical field of concrete creep and elastic modulus test devices, and relates to a lever horizontal pull type concrete creep and elastic modulus test device. Background technique [0002] Existing concrete creep and elastic modulus tests need to use special loading equipment. The test process consumes too many raw materials and labor, and the test accuracy is not high. The present invention designs a lever-type creep and elastic modulus test device with a simple structure. , can test the creep and modulus of elasticity of concrete at various ages. Contents of the invention [0003] The purpose of the present invention is to provide a lever horizontal pull type concrete creep and modulus of elasticity test device, which solves the problems of complex structure, unstable load control during loading and low test accuracy of the existing test device. [0004] The technical scheme adopted in the present invention comprises ...
