First, product introduction;

The mortar point load meter is developed according to GB / T50315-2000 << Technical Regulations for On-site Inspection of Masonry Engineering >>. It is an instrument for testing the strength of masonry mortar. It can be directly tested on site or in the laboratory without affecting the wall Stress performance, with the characteristics of easy detection, convenient operation, short time required, and high test accuracy, can fully meet the objective needs of on-site quality control of masonry projects and quality appraisal and evaluation of old and ancient buildings.


二、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**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 load meter consists of a worm wheel, a worm mechanical loading system, a pressure sensor and a microcomputer peak display.The sensor is installed on the base of the loading system.The peak display and the loading system are connected by wires.

During work, place the pre-prepared mortar sample on the indenter, and slowly turn the handle of the point load meter clockwise with your hand to move the lifting screw downward.When the loading head is against the mortar sample **, Pressure load, and then slowly and uniformly apply the load until the test piece is broken. At this time, the microcomputer peak display keeps the large A load.

★ Dimensions: 350X150X20mm


四、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**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, use method:

★ Before using the instrument, first connect the sensor to the microcomputer peak display, then connect the power to turn on the power switch on the display. At this time, the "load" indicator is on, and observe if the number on the display is zero. You should press the "Zero" key to clear it.

★ Press the "Peak" key, the peak indicator light is on, and the load can be applied at this time. When the test piece is broken, the display shows the value of A, the unit is N.

When the next test piece is pressed, press the "Peak" key to light up the loading indicator. The previous test data is eliminated. If the value displayed on the display is zero (smaller values drift on the display is normal), then press the "Peak" key. Make the "peak" indicator light, and then load for the next test. If the display shows a large value, press the "zero" key to clear it when the "load" light is on. Repeat the above procedure for each test. However, when the peak indicator is off, the display has no peak protection function, and the displayed value will automatically disappear with unloading.

Large pieces of mortar peeled at each measuring point are processed (or selected) into test pieces that meet the following requirements: thickness 5-20mm, estimated action radius 15-25mm, and the large surface should be flat, but its edges are not required to be very regular .

Draw the point of action on the mortar sample, and measure its thickness t with a caliper, accurate to 0.1 mm.

Place the mortar sample on the lower loading head, align the upper and lower loading heads with the pre-drawn action points, and slowly turn the handle of the point loader clockwise with your hands to move the lifting screw down through the worm wheel and worm drive. When the loading head is pressed against the mortar sample, a compressive load is generated, and then the load is slowly and uniformly applied until the test piece is broken, and the loading is stopped at this time.

After recording the peak display readings, insert the formula to calculate the intensity.The reading unit of the point charge meter display is N.

★ Splice the damaged specimens as they are, and measure the short distance A from the actual point of load to the edge of the specimen as the radius of action, accurate to 0.1 mm.

Note: Do not directly press the upper and lower loading heads. If the upper and lower loading heads are required to perform this inspection, a mortar sheet must be placed between the upper and lower loading heads to avoid damage to the loading heads.

★ Verification of instrument

The instrument has been calibrated with the standard instrument before leaving the factory. The sensor needs to be re-calibrated after a period of use. The user can remove the four fixing screws on the back cover of the display and remove the front panel. (The potentiometer below is used to adjust the zero point).

The indicator is under the "loading" light, and the loading and unloading test is repeated. After the verification, the adjustment screw is sealed tightly to prevent changes from vibration.


五、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.

Five, maintenance and upkeep:

After the instrument is used, it should be cleaned up and packed in a box for future use

The microcomputer peak display is assembled with integrated circuits, and the power supply voltage should be stable in the range of 220V ± 5V when in use.

The instrument should be used and stored in a dry place indoors. Avoid exposure to sunlight, rain and moisture to extend the service life.

★ Yellow dry oil should be regularly injected into the worm gear box to keep it lubricated.
