Description

A mortar consistency measuring device

technical field

The utility model relates to the technical field of testing instruments for building materials, in particular to a mortar consistency measuring device.

Background technique

The technology of ready-mixed mortar is developing rapidly. In the process of quality inspection of ready-mixed mortar, whether it is incoming inspection or outgoing inspection, the first thing to measure is the mortar consistency, and adjust the amount of water and admixture according to the value of the mortar consistency. , the experimental operation is in accordance with the industry standard "JGJ/T 70-2009 Basic Performance Test Method Standard for Building Mortar".

The mortar consistency meter is used to measure the fluidity of the mortar. The general fluidity is also called the consistency. The consistency of the mortar is to use a standard cone with a certain geometric shape and weight to sink freely into the mortar mixture by its own weight. Indicated by depth. When the standard cone no longer sinks into the mortar, tighten the screw and turn the pin nut until the rack reaches this depth, then the measured sinking depth can be read on the dial, and the corresponding sinking depth can be found at this depth. volume. The mortar must have good workability before hardening, including fluidity, and a large amount of sinking indicates good fluidity. During operation, the tester puts the mortar mixture into the container at one time, adjusts the test cone until the tip contacts the mortar surface, tightens the brake screw so that the lower end of the side bar of the rack just touches the upper end of the slide bar, and points the pointer at the zero point. ; Unscrew the brake screw, and at the same time use a stopwatch to time, after 10 seconds, fix the screw immediately, put the lower end of the side bar of the rack in contact with the upper end of the slide bar, and read the sinking depth from the dial, which is the value of the mortar consistency. However, the commonly used mortar consistency meter cannot accurately control the amount of mortar loaded into the conical container, and the intuitive control of the height from the top of the conical container is prone to errors. If the mortar loaded in the conical container is too full, then The falling of the vertebral body will cause the mortar to overflow and contaminate the experimental equipment; if the distance between the loaded mortar and the top of the conical container is too large, the final reading will be biased.

Utility model content

In order to solve the phenomenon that the amount of mortar loaded into the conical container cannot be controlled in the prior art, resulting in the contamination of experimental instruments and deviations in readings, the utility model provides a mortar consistency measuring device. The conical container of the device is equipped with Internal marking line.

The technical scheme adopted by the utility model to solve the above-mentioned problems is: a mortar consistency measuring device, including a bracket, an indicator plate, a test cone, a cone-shaped container and a base connected to the bracket, and the bracket is provided with all perpendicular to the bracket. The first cross arm and the second cross arm, the first cross arm is provided with a measuring rod capable of driving the pointer in the indicating plate to rotate, and the measuring rod passes through the linkage piece and is clamped by the hoop to the sliding rod on the second cross arm. One end is connected, and the other end of the slide rod is provided with a test cone, and the base directly below the test cone is provided with a tapered container with an internal marking line on the inner cone surface, and the internal marking line is set at a position 1cm away from the port of the tapered container.

The central axis of the slide rod coincides with the center of the tapered container.

Beneficial effects of the present utility model: the conical surface of the conical container of the present utility model is provided with a 1cm internal marking line, which can control the amount of mortar loaded in the conical container and prevent the experimental instrument from overflowing due to too much mortar. pollution, which improves the accuracy of the measurement results; during the measurement process, loosen the hoop clamp after zeroing the indicator plate, and the linkage piece slides down so that the measuring rod drives the pointer of the indicator plate to rotate, reducing the impact of friction on the experimental results. The measurement accuracy is improved, and the mortar consistency value can be read directly on the indicator plate, which simplifies the measurement process.
