In-situ detection device for compressive strength of sintered common brick by clamping-twisting method

Abstract

The invention relates to an in-situ detection device for compressive strength of a sintered common brick by a clamping-twisting method. The in-situ detection device comprises two metal clamping platessymmetrically arranged on side surfaces of a cuboid sample in a sintered common brick; the metal clamping plates are fixedly connected with metal chock plugs and thickness adjusting gaskets which areplugged in the metal clamping plates through fixing bolts; the cuboid sample is covered by the metal clamping plates, the metal chock plugs and the thickness adjusting gaskets; and the metal chock plugs are connected with a digital display torque wrench through metal hexagon heads. The cuboid sample in the sintered common brick is clamped through the metal clamping plates, the metal chock plugs,the thickness adjusting gaskets and the fixing bolts, and then torsion is applied to the cuboid sample through the metal hexagon heads by adopting a digital display torque wrench until the cuboid sample is twisted and damaged, and the maximum torsion value is read; the compressive strength of the sintered common brick is presumed according to a conversion formula established between the compressive strength and the torsion value of the sintered common brick, detection is accurate, design is reasonable, and practicability is high.

Description

technical field [0001] The invention relates to an in-situ detection device for the compressive strength of sintered common bricks by pinching and twisting. Background technique [0002] Compressive strength is one of the most important performance parameters of sintered ordinary bricks, which is directly related to the quality, safety and normal use of masonry and even the entire project. Therefore, in-situ testing of the compressive strength of sintered ordinary bricks is a very important task. [0003] In the prior art, the commonly used method for in-situ detection of the compressive strength of sintered ordinary bricks is mainly the rebound method. This method is based on the relationship between the surface hardness and strength of sintered ordinary bricks, and the brick rebound meter is used for testing, and the compressive strength of sintered ordinary bricks is estimated. compressive strength. The shortcomings of this detection method: (1) The accuracy of the comp...
