Circular ring tension cutting method detection device for solid concrete compressive strength

Abstract

Provided in the invention is a circular ring tension cutting method detection device for the solid concrete compressive strength. The device comprises a T-shaped cylindrical sample arranged in solid concrete, and a cylindrical pressure head and a miniature screw oil jack are sequentially arranged on the T-shaped cylindrical sample. The cylindrical pressure head is connected with the head of the miniature screw oil jack through a spherical support; a circular plate base is mounted at the tail part of the miniature screw oil jack; a force application structure for applying a pulling and cuttingforce is mounted on the circular plate base; a digital pressure gauge is further mounted on the circular plate base; the periphery of the circular plate base is connected with an L-shaped counter-force pull ring capable of hooping the T-shaped cylindrical sample; the T-shaped cylindrical sample, the cylindrical pressure head, the miniature screw oil jack, the circular plate base and the L-shaped counter-force pull ring are coaxial in longitudinal axis. According to the invention, the T-shaped cylindrical sample in solid concrete is hooped by the L-shaped counter-force pull ring; a pulling andcutting force is applied to the T-shaped cylindrical sample through the cylindrical pressure head, the miniature screw oil jack and the L-shaped counter-force pull ring until the T-shaped cylindricalsample is damaged in a tension cutting mode; the maximum tension cutting force value is read, the concrete compressive strength is presumed according to a conversion formula established between the concrete compressive strength and the tension cutting force value. The application range is wide, the practicability is high, and detection is accurate.

Description

technical field [0001] The invention relates to a device for detecting the compressive strength of solid concrete with a ring drawing method. Background technique [0002] Compressive strength is one of the important performance parameters of concrete, which is directly related to the quality, safety and normal use of concrete components and even the entire project. Therefore, testing the compressive strength of solid concrete is a very important task. [0003] In the prior art, there are many common methods for testing the compressive strength of solid concrete, which are as follows: [0004] (1) Shear compression method. Using a concrete shear pressure meter, a pressure perpendicular to the pressure-bearing surface is applied to the surface of the right-angled side of the concrete member, so that the right-angled side of the concrete member produces local shear compression damage, and the compressive strength of the concrete member is estimated according to the shear pre...
