The invention relates to an instrument for detecting mortar strength by a pressure selecting method. The instrument for detecting the mortar strength by the pressure selecting method comprises left and right pressure-selecting round flat pressure heads, a counter force frame, a driving screw, a loading handle, a concentric centering self-levelling system and an intelligent data acquisition subsystem, wherein the left pressure-selecting round flat pressure head corresponds to the right pressure-selecting round flat pressure head; the right pressure-selecting round flat pressure head is arranged on the concentric centering self-levelling system; the concentric centering self-levelling system is linked with the loading handle through the driving screw; and the left pressure-selecting round flat pressure head is arranged on an engine base provided with the intelligent data acquisition subsystem and is connected with the output end of the intelligent data acquisition subsystem. Compared with an instrument using the traditional method, the instrument for detecting the mortar strength by the pressure selecting method improves the precision of a detection result, has small damage to the original structure, completely solves the problem of detecting the on-site compression strength of a large amount of masonry mortar due to the excellent technical effect, has a wide application range, small and exquisite volume and little influence caused by environmental factors, and is loaded manually, convenient to operate, and suitable for large-range popularization.
Description
technical field [0001] The invention relates to a detection device, in particular to a pressure-selective method mortar strength detector. Background technique [0002] The construction industry is a major pillar industry in my country, which is related to the national economy and people's livelihood of all citizens. Moreover, as the global seismic belt has entered a new active cycle in the past decade, the situation of structural seismic safety is severe. Masonry engineering is the most extensive and large-scale structural form in my country at present. Among them, the strength of masonry mortar is an important parameter that must be measured in engineering testing. This parameter index is also an important basis for evaluating the engineering quality, safety, and life of masonry projects, as well as for structural seismic safety assessment. Therefore, how to evaluate the strength of masonry mortar more scientifically, accurately, efficiently and safely is an important t...
