It can be directly tested at the site or laboratory without affecting the wall. The physical force performance, with the characteristics of easy detection, convenient operation, short time required and high test accuracy, can fully meet the objective requirements of quality control of masonry engineering site and quality assessment and assessment of old and ancient houses.

二,砂浆点荷仪结构与原理;
点荷仪由蜗轮、蜗杆机械加荷系统,压力传感器和微电脑峰值显示器组成,传感器安装在加荷系统的底座上,峰值显示器和加荷系统用导线连接.
工作时,将预先取好的砂浆试样放在压头上,用手顺时针慢慢转动点荷仪的手柄,使升降丝杠向下移动,当加载头顶住砂浆试样时就产生了压力荷载,然后缓慢均匀的施加荷载直至试件破坏,此时微电脑峰值显示器将A大荷载保持住.
Second, structure and principle
The point loader consists of a worm gear, a worm mechanical loading system, a pressure sensor and a microcomputer peak display. The sensor is mounted on the base of the loading system, and the peak display and the loading system are connected by wires.
When working, put the pre-taken mortar sample on the indenter, slowly turn the handle of the point-loader clockwise by hand to move the lifting screw downward, and generate pressure when the loading head is against the mortar sample. Load, then apply the load slowly and evenly until the specimen breaks, at which point the microcomputer peak display will hold the maximum load.

四,砂浆点荷仪使用方法:
★ 仪器使用前,先将传感器与微电脑峰值显示器的连线接好,然后接通电源将显示器上电源开关打开,此时“加荷”指示灯亮,观察显示器上的数字是否为零若不为零应按“置零”键,  使其清零.
★按下“峰值”  键,峰值指示灯亮,此时可以加荷,当试件破坏时显示器显示的示值为此试件的A大强度值,单位为N.
当做下一个试件时需按下“峰值”键使加荷指示灯亮,上一个试验数据消除,若显示器显示的数值为零(显示器有较小数值飘移属正常现象)再按下“峰值”  键使“峰值”指示灯亮,此时可加荷做下一个试验,若显示器显示数值较大在“加荷”灯亮状态下按“置零”键使其清零.每次试验均需重复上述程序,但峰值指示灯不亮时显示器没有峰值保护功能,显示数值会随着卸荷而自动消除.
★将每个测点处剥离出的砂浆大片加工成(或选取)符合下列要求的试件:厚度  5-20mm,预估作用半径15-25mm,大面应平整,但其边缘不要求非常规则.
★在砂浆试件上画出作用点,用卡尺测其厚度t,精确至0.1  mm.
★将砂浆试样放置在下加载头上,上、下加载头对准预先画好的作用点,用手顺时针慢慢转动点荷仪的手柄,通过蜗轮、蜗杆传动使升降丝杠向下移动,当加载头顶住砂浆试样时就产生了压力荷载,然后缓慢均匀的施加荷载,至试件破坏,此时停止加荷.
★记录下峰值显示器读数后,代入公式,计算强度,点荷仪显示器的读数单位为N.
★将破坏后的试件拼接成原样,量测荷载实际作用点中心到试件边缘的A短距离即为作用半径,精确至0.1  mm。
★注意:不要将上下加载头直接顶压,如需上下加载头来做本项检验时,必须在上下加载头之间放置砂浆片,以免损坏加载头.
★仪器的检定调整
本仪器出厂前已与标准器进行检定.传感器经过一段时间使用需重新检定时,用户可将显示器后盖四个固定螺钉卸下取下前面板,旋转数码显示块左下角(上面的)电位器上的螺钉即可.(下面的电位器是用来调整零点的)调整时应将显
示器处于“加荷”灯亮状态下进行,反复加荷卸荷试验.检定后用稠油漆将调整螺钉封牢,以免受震动发生变化.
Fourth, the method of use
★ Before using the instrument, connect the sensor to the peak display of the microcomputer, then turn on the power to turn on the power switch on the display. At this time, the “Load” indicator lights up, and observe if the number on the display is zero. Press the “Zero” button to clear it.
★Press the “Peak” button, the peak indicator light is on, and the load can be applied at this time. When the test piece is broken, the display value of the display is the maximum intensity value of the test piece, and the unit is N.
When the next test piece is pressed, press the “Peak” button to make the load indicator light, and the previous test data is eliminated. If the display shows zero value (the display has a small value drift is normal) and then press the “Peak” button. Make the “Peak” indicator light, then you can load it for the next test. If the display shows a large value, press “Zero” to clear it when the “Load” light is on. Repeat the above procedure for each test. However, if the peak indicator is not lit, the display does not have a peak protection function, and the displayed value is automatically cancelled as the unloading is performed.
Process the large piece of mortar peeled off at each measuring point into (or select) the test piece that meets the following requirements: thickness 5-20mm, estimated working radius 15-25mm, large surface should be flat, but its edge does not require very regular .
★ Draw the action point on the mortar test piece and measure the thickness t with a caliper to the nearest 0.1 mm.
★ Place the mortar sample on the lower loading head, the upper and lower loading heads are aligned with the pre-drawn action points, slowly turn the handle of the point-of-charge instrument clockwise by hand, and move the lifting screw downward through the worm gear and the worm drive. When the loading head is pressed against the mortar sample, a pressure load is generated, and then the load is applied slowly and evenly until the test piece is broken, and the loading is stopped at this time.
★ After recording the peak display reading, substitute the formula to calculate the intensity. The unit of reading of the point meter display is N.
★Splicing the damaged specimen into the original sample, measuring the shortest distance from the center of the actual application point of the load to the edge of the specimen is the radius of action, accurate to 0.1 mm.
★ Note: Do not press the upper and lower loading heads directly. If you need to load the head up and down to do this test, you must place a mortar between the upper and lower loading heads to avoid damage to the loading head.
★ instrument calibration adjustment
The instrument has been checked with the standard before leaving the factory. The sensor needs to be re-checked after a period of use. The user can remove the four fixing screws on the back cover of the display to remove the front panel and rotate the potentiometer in the lower left corner (above) of the digital display block. The screw on the top can be used. (The potentiometer below is used to adjust the zero point.) It should be displayed when adjusting.
The display is in the state of "loading" light, repeated loading and unloading test. After the verification, the adjusting screw is sealed with thick paint to avoid vibration changes.

五,砂浆点荷仪维护与保养:
★仪器使用完毕,应清理干净,装入箱中备用
★微电脑峰值显示器采用集成电路组装,在使用时电源电压应稳定在220V±5V范围内.
★仪器在使用和存放均应于室内干燥地方,切忌暴晒,雨淋和受潮,以延长使用寿命.
★蜗轮箱内应定期注黄干油,保持润滑.
Fifth, maintenance and maintenance:
★ After the instrument is used, it should be cleaned up and put into the box for backup.
★Microcomputer peak display is assembled by integrated circuit. When using, the power supply voltage should be stable within 220V±5V.
★The instrument should be used and stored in a dry place indoors, avoid exposure, rain and moisture to prolong the service life.
★ The worm gear box should be regularly filled with yellow dry oil to keep it lubricated.
