推出法砂浆强度检测仪是依据国家标准GB/T50315《砌体工程现场检测技术标准》中“推出法”的技术要求所研制的测试砌筑砂浆强度的专用仪器。其使用方法是在砌体的一块砖上测试砌体的砂浆强度,将被测砖面及侧面的砂浆清除,把仪器安装在砖上手动加荷侧向推砖,当砖被推出时,由高精度的荷载传感器通过仪表峰值显示器将力值显示出来,然后换算为砂浆强度。

The launching mortar strength tester is a special instrument developed to test the strength of masonry mortars in accordance with the technical requirements of the "rolling out method" in the national standard GB / T50315 "Technical Standards for On-site Inspection of Masonry Engineering". The method of use is to test the strength of the mortar on a brick of the masonry, remove the mortar on the tested brick surface and the side, install the instrument on the brick and manually load the bricks laterally. The high-precision load sensor displays the force value through the instrument peak display, and then converts it into mortar strength.

Technical parameters of mortar strength tester introduced:
■ Rated thrust: 30KN
■ Relative measurement range: 20 ~ 80%
■ Relative error of displayed value: ± 3%
■ Rated travel: 80mm
■ Force value display instrument A small resolution: 0.05KN
■ Range of force value: 0 ~ 30KN
■ With force peak holding function
■ The instrument reading display is stable, the reading drift within 4h is less than 0.05KN
■ Measurement point selection and layout:
(1) The measuring points should be evenly arranged on the wall, and the reserved openings during construction should be avoided.
(2) The pressure-bearing surface of the pushed brick can be smoothed with a grinding wheel and should be cleaned up.
(3) The thickness of the horizontal gray joint under the pushed brick shall be 8-12mm.
(4) Before the test, the pushed bricks should be numbered, and the appearance of the wall should be recorded in detail.
