Extrusion device for concrete strength test

Abstract

The invention relates to the technical field of extrusion devices, in particular to an extrusion device for a concrete strength test. The device comprises an n-shaped bent plate-shaped control seat, apressure column is arranged in an inner cavity of the control seat, the pressure column is columnar, the side wall of a column body is a vortex curved surface, and a central shaft penetrates throughthe middle part of the pressure column; and the end part of the central shaft extends into the circular plate groove formed in inner wall of control seat. On the basis of the structural design, rapiddetection work of a concrete plate is achieved, the concrete plate is placed on the sliding plate, the pressure column is rotated, after the concrete plate is broken, the position of the floating plate in the control barrel is observed, and then the discharged water amount can be mastered; the discharged water reflects the pressure critical point when the concrete slab is broken, namely, the descending height of the sliding plate is fed back, the larger the shrinking degree of the rubber bag is, the larger the generated counter-acting force is, then the sliding plate provides certain reverse pressure to act on the concrete slab, the pressure column and the sliding plate are matched to clamp the concrete slab, and the function is stable and powerful.

Description

technical field [0001] The invention relates to the technical field of extrusion devices, in particular to an extrusion device for concrete strength test. Background technique [0002] In the concrete strength test process in the prior art, the concrete slab is placed in the clamping mechanism, and the concrete slab is exerted pressure through the clamping block to observe the deformation and damage of the concrete block under the pressure. The ordinary measuring device has low working quality, and the High-precision pressure machines are expensive, and it is uneconomical to use such machines for common measurement needs. [0003] If a kind of extruding device for testing can be invented, the function is stable and powerful, and the manufacturing cost is low, the problem can be solved. For this reason, we provide a kind of extruding device for concrete strength test. Contents of the invention [0004] The object of the present invention is to provide an extrusion device f...
