Embodiment 1

[0024] like figure 1 As shown, a mortar conveying force measurement tester includes: a sample cylinder 1, a propeller 2 and a digital display panel 3; Composition, the left end of the push rod 4 is provided with a 48mm baffle 9, the right end is provided with a sensor 5, the connecting piece 6 is fixedly connected with the push rod 4 and the slider 7, the slider 7 runs on the manual screw rod 8, and the manual screw rod The rotation of 8 drives the push rod 4 connected on the slider 7 to move horizontally; the end of the sample cylinder 1 close to the sensor 5 is an open end, and a measurement marking line 11 is provided at a distance of 50 mm from the open end, and a steel pipe is provided at the other end. Seal 10, the center of the steel seal 10 is provided with a 30mm round hole; the sensor 5 is connected to the digital display panel 3; the sample cylinder 2 is placed horizontally, and the open end of the sample cylinder 2 is facing the push rod The baffle 9 of 4; the baf...

Embodiment 2

[0026] A method for measuring mortar conveying force, comprising the steps of:

[0027] a. Put 200mm of special mortar for mechanical spraying into the sample cylinder 1, that is, install it to the measurement mark 11, use a slotting knife to insert and pound it several times until it is dense, uniform and free of gaps, and then put it into the non-absorbent material. A gasket with a diameter of 48mm prevents the mortar from spilling during the inclination of the sample cylinder 1;

[0028] b. Fix the sample cylinder 1 horizontally in the fixed snap ring, adjust the baffle plate 9 of the push rod 4 to be in contact with the gasket; set a receiving tray under the 30mm round hole at the other end of the sample cylinder 1;

[0029] c. Adjust the digital display panel 3 to zero, manually rotate the manual screw 8, and drive the push rod 4 to horizontally push the special mortar for mechanical spraying to move forward; and observe the reading change of the digital display panel 3 a...

Abstract

The invention discloses a mortar conveying capacity measurement tester which comprises a test specimen tube, a propeller and a digital display panel. The propeller consists of a push rod, a sliding block, a sensor and a manual screw rod; a baffle is arranged at the left end of the push rod; the sensor is arranged at the right end of the push rod; the push rod is fixedly connected with the sliding block by a connecting piece; the sliding block operates on the manual screw rod; one end of the test specimen tube, which is close to the sensor, is an open end; a measurement marked line is arranged at a position which is at a distance of 50mm with the open end; a steel sealing opening is formed in the other end of the test specimen tube; a 30mm round hole is formed in the center of the steel sealing opening; the sensor is connected with the digital display panel; the test specimen tube is horizontally placed; the open end of the test specimen tube is over against the baffle of the push rod. The invention further discloses a mortar conveying capacity measurement testing method. The mortar conveying capacity measurement tester is simple in structure and convenient to use; measurement on mortar conveying capacity can be effectively carried out, analysis data is provided for construction advantages and disadvantages of mortar, the blank in China is filled, and the mortar conveying capacity measurement tester and testing method have very high application value.

Description

technical field [0001] The invention relates to the field of advanced equipment for measuring building materials, in particular to a mortar conveying force measuring tester and a test method. Background technique [0002] With the continuous advancement of the application of ready-mixed mortar, the mechanized construction technology of ready-mixed mortar has gradually become the focus of attention and an important direction for the development of ready-mixed mortar. In the long run, the operation mode of construction mortar must be changed to mechanization and automation, and the development of ordinary mortar mechanized construction (referred to as machine sprayed mortar) technology will be one of the important directions of future development. Mechanized construction has the advantages of high efficiency, low labor intensity, good project quality, environmental protection, and less material loss, showing strong market competitiveness. [0003] The mechanized construction ...
