Concrete shrinkage and creep analysis device and method

Abstract

The invention relates to the technical field of concrete shrinkage and creep, and discloses a concrete shrinkage and creep analysis device which comprises a base, a supporting rod is fixedly mounted on the inner wall of the base, a pressing plate is fixedly mounted at the top end of the supporting rod, a top column is fixedly mounted at the top end of the base, and a storage plate is fixedly mounted at the top end of the top column. A telescopic rod is fixedly installed at top end of inner wall of top column. According to the concrete shrinkage creep analysis device and method, a hinge seat is rotationally matched with a rope seat to start to wind a pull rope, movement of a moving plate drives a guide wheel to roll along the inner wall of a supporting rod, and movement of a connecting plate drives a movable seat to slide along the inner wall of a storage groove under the assistance of a limiting rod; and the movable seat is in sliding fit with the supporting rod to drive the butt strap to move, and when the area of the bottom end of concrete is larger than that of the top end of the storage plate, the butt strap just moves to be matched with the storage plate in an aligned mode, so that the effect of synchronously adjusting the bearing area of the bottom end according to the size and shape of the concrete is achieved.

Description

technical field [0001] The invention relates to the technical field of concrete shrinkage and creep, in particular to a concrete shrinkage and creep analysis device and a method thereof. Background technique [0002] Cement is used as the main cementitious material, and water, sand and stones are filled in, and the proportion is well controlled for mixing and molding, and finally concrete is obtained. Since concrete is often used in the construction field, the control of concrete indicators is particularly strict, and it is usually necessary to use Creep analysis was carried out on the formed concrete in the early stage. However, due to the different sizes of the traditional creep analysis devices, it usually needs to be replaced according to the size of the formed concrete during analysis, which is too cumbersome for actual construction applications. [0003] Therefore, a concrete shrinkage and creep analysis device and its method are needed, which have the function of adju...
