Technical Field
[0001] This utility model belongs to the technical field of cement mortar testing equipment, and in particular relates to an auxiliary tooling for testing the flowability of cement mortar. Background Technology
[0002] Cement mortar flowability is a measure of the fluidity of cement mortar, which depends on the water demand of the cement. Currently, a cement mortar flowability tester is commonly used to test the flowability of cement mortar. The testing method involves placing a mold on the test panel of the cement mortar flowability tester, ensuring the mold is centered on the panel. Cement mortar is then poured into the mold. After the cement mortar is scraped with a scraper and tamped with a tamping rod, the mold is removed. The cement mortar flowability tester is then activated, causing the test panel to vibrate for a certain period. After the vibration ends, the average diameter of the cement mortar spread on the test panel is measured to determine the flowability of the cement mortar, thereby judging the water demand of the cement.
[0003] Currently, when measuring the flowability of cement mortar by measuring the average diameter of the spread on the test panel, it is necessary to manually measure with a tape measure, and the tape measure must pass through the center to ensure the accuracy of the measurement. This method is quite cumbersome. Summary of the Invention
[0004] The purpose of this invention is to address the problems existing in the prior art by providing an auxiliary tooling for testing the flowability of cement mortar. When measuring the flowability of cement mortar, the reading can be taken directly, eliminating the need to manually measure the average diameter of the extended section on the test panel. This ensures accuracy while simplifying the test procedure.
[0005] To achieve the above objectives, the utility model employs the following technical solution: an auxiliary tooling for testing the flowability of cement mortar, comprising a testing disc, wherein an annular groove is formed on the upper surface of the testing disc, the center of the annular groove coincides with the center of the testing disc, a plurality of measuring grooves are formed on the upper surface of the testing disc surrounding the annular groove, one end of the measuring groove is aligned with the center of the testing disc, a scale is provided in the measuring groove, a plurality of reading grooves are engraved on the testing disc, a transparent cover is provided on the top of the testing disc to cover the testing disc, and a test mold is also included, wherein a positioning disc cover that can be fitted onto the transparent cover is provided at the bottom end of the outer wall of the test mold.
[0006] By the above technical scheme, when judging the fluidity of cement mortar by measuring the average diameter of the cement mortar expansion on the detection disc, the staff can directly observe the staff ruler through the transparent cover, read the average diameter of the cement mortar expansion, and no longer need to manually measure the average diameter of the expansion with a tape measure, thereby avoiding the error of manual measurement, effectively ensuring the measurement accuracy, simplifying the test steps, and effectively improving the experimental efficiency. Meanwhile, by arranging the positioning disc cover which can be sleeved on the transparent cover at the bottom of the test mold, the stability of the test mold is enhanced, and more importantly, when the positioning disc cover is sleeved on the transparent cover, the test mold is necessarily located at the center position of the detection disc, thereby ensuring the accuracy and reliability of the subsequent measurement.
[0007] As a further technical scheme, the outer diameter of the circular groove is the same as the inner diameter of the bottom of the test mold. Through this technical scheme, the staff does not need to subtract the diameter of the original state of the cement mortar in the test mold when reading, and the data read by the staff ruler is the expansion amount of the cement mortar, thereby making the detection process simpler.
[0008] As a further technical scheme, the other end of the measuring groove extends to the outer side wall of the detection disc. Through this technical scheme, the staff ruler can be completely laid out, thereby expanding the reading range as much as possible.
[0009] As a further technical scheme, the reading line groove is a circular ring type, and the reading line groove coincides with the center of the detection disc. Through this technical scheme, the reading line groove can be uniformly distributed on the detection disc, facilitating measurement and reading in multiple directions. At the same time, the circular ring type design also improves the accuracy and consistency of reading.
[0010] As a further technical scheme, the diameters of the plurality of reading line grooves are different, and the spacings between the adjacent two reading line grooves are equal. This technical scheme provides multiple measurement ranges and accuracies, and appropriate reading line grooves can be selected according to different detection requirements. At the same time, the equal spacing design also ensures the continuity and comparability of the measurement results.
[0011] As a further technical scheme, a qualified mark coating is applied to the area between the two reading line grooves. Through this technical scheme, when quickly judging whether the cement mortar is qualified or not, it only needs to observe whether the cement mortar diffusion exceeds this unqualified area.
[0012] As a further technical scheme, the inner top wall of the transparent cover is provided with an insertion strip, the surface of the insertion strip is provided with a damping pad, the top of the detection disc is provided with a plug hole matched with the insertion strip, and the transparent cover is plugged with the detection disc. This technical scheme enables the transparent cover to be fixed on the detection disc, preventing displacement or falling during the measurement process. At the same time, the plug-in mode is also convenient for disassembling and cleaning the transparent cover.
[0013] As a further technical solution, the bottom center of the detection disc is provided with a mounting cylinder with internal threads, and the mounting cylinder is connected to the test bench. This technical solution enables the detection disc to be conveniently fixed on the test bench.
[0014] Compared with the prior art, the utility model has the advantages that: 1. When the average diameter of cement mortar expansion on the measurement detection disc is measured to determine the fluidity of cement mortar, the staff can directly observe the staff ruler through the transparent cover, read the average diameter of cement mortar expansion, and no longer need to manually measure the average diameter of expansion with a tape measure, avoiding the error of manual measurement, effectively ensuring the measurement accuracy, simplifying the test steps, and effectively improving the experimental efficiency; 2. The outer diameter of the circular groove is the same as the inner diameter of the test mold bottom, so that the staff does not need to subtract the diameter of the original state of the cement mortar in the test mold when reading, and the data read by the staff ruler is the expansion amount of the cement mortar, making the detection process simpler; 3. The positioning disc cover is set on the outside bottom end of the test mold and can be sleeved on the transparent cover, which not only enhances the stability of the test mold, but also, when the positioning disc cover is sleeved on the transparent cover, the test mold is necessarily in the center position of the detection disc, ensuring the accuracy and reliability of subsequent measurement; 4. By setting the qualified identification coating, when quickly judging whether the cement mortar is qualified or not, only the observation of whether the cement mortar diffusion exceeds the unqualified area is needed, which improves the experimental efficiency; 5. By setting multiple reading line grooves, measurement and reading in multiple directions are facilitated, and the accuracy and consistency of reading are improved. BRIEF DESCRIPTION OF DRAWINGS

[0023] like Figure 1 As shown in Figure 4, this embodiment provides an auxiliary tooling for testing the flowability of cement mortar, including a testing disc 1. A circular groove 11 is formed on the upper surface of the testing disc 1, and the center of the circular groove 11 coincides with the center of the testing disc 1. A plurality of measuring grooves 12 are formed on the upper surface of the testing disc 1, surrounding the circular groove 11. One end of the measuring groove 12 is aligned with the center of the testing disc 1. A scale 13 is provided in the measuring groove 12. A plurality of reading lines 14 are engraved on the testing disc 1. A transparent cover 2 is provided on the top of the testing disc 1 to cover the testing disc 1. The testing disc 1 also includes a test mold 3. A positioning disc cover 31 that can be fitted onto the transparent cover 2 is provided at the bottom of the outer wall of the test mold 3.
[0024] When measuring the average diameter of the cement mortar spread on the test plate 1 to determine the flowability of the cement mortar, the staff can directly observe the scale 13 through the transparent cover 2 to read the average diameter of the cement mortar spread. This eliminates the need to manually measure the average diameter with a tape measure, avoiding errors from manual measurement, effectively ensuring measurement accuracy, simplifying the test procedure, and effectively improving experimental efficiency. In addition, by setting a positioning plate cover 31 on the bottom outer side of the mold 3, which can be fitted onto the transparent cover 2, not only is the stability of the mold 3 enhanced, but more importantly, when the positioning plate cover 31 is fitted onto the transparent cover 2, the mold 3 will inevitably be in the center position of the test plate 1, ensuring the accuracy and reliability of subsequent measurements.
[0025] In practical applications, the transparent cover 2 is directly fitted onto the detection plate 1 and can be directly removed from the detection plate 1. In order to ensure that when multiple experiments are required, the transparent cover 2 can be replaced after each experiment to avoid the previous mortar adhering to the transparent cover 2 after the previous experiment, thus affecting the subsequent experiments.
[0026] In addition, in order to make the reading more convenient, LED light strips can be arranged inside the measuring groove 12 and on the side of the staff ruler 13 to provide a bright environment for the staff ruler 13. Moreover, in order to ensure the service life of the light strips, the inside of the measuring groove 12 is filled with a buffer cotton pad to prevent the light strips from being damaged during the vibration of the detection disc 1.
[0027] In the embodiment, the outer diameter of the circular groove 11 is the same as the inner diameter of the bottom of the test mold 3, which makes it unnecessary for the staff to subtract the original diameter of the cement mortar in the test mold 3 when reading, and the data read by the staff ruler 13 is the expansion amount of the cement mortar, thereby making the detection process simpler.
[0028] As shown in Figure 2 , the other end of the measuring groove 12 extends to the outer sidewall of the detection disc 1. Through the technical scheme, the staff ruler 13 can be fully laid out to maximize the reading range.
[0029] As shown in Figure 2 , in the embodiment, the reading line 14 groove is circular, and the reading line 14 groove coincides with the center of the detection disc 1. Through the technical scheme, the reading line 14 groove can be evenly distributed on the detection disc 1, facilitating measurement and reading in multiple directions. At the same time, the circular design also improves the accuracy and consistency of the reading.
[0030] In the embodiment, the diameters of the plurality of reading line 14 grooves are different, and the spacings between adjacent two reading line 14 grooves are equal. The technical scheme provides multiple measurement ranges and accuracies, which can be selected according to different detection requirements. At the same time, the equal spacing design also ensures the continuity and comparability of the measurement results.
[0031] In the embodiment, an insertion strip is arranged on the inner top wall of the transparent cover 2, a damping pad is arranged on the surface of the insertion strip, a plug hole adapted to the insertion strip is arranged on the top of the detection disc 1, and the transparent cover 2 is plugged with the detection disc 1. The technical scheme makes the transparent cover 2 fixed on the detection disc 1, and the damping pad makes the insertion strip more tightly inserted into the plug hole to prevent displacement or falling during the measurement. At the same time, the plug-in mode is also convenient for disassembling and cleaning the transparent cover 2.
[0032] In application, the transparent cover 2 can also be glued to the detection disc 1.
[0033] As shown in Figure 4 , a mounting cylinder 4 with internal threads is arranged at the bottom center of the detection disc 1, and the mounting cylinder 4 is connected with a test bench 5. The technical scheme makes the detection disc 1 conveniently fixed on the test bench 5. Embodiment

[0035] It should be noted that the standard for selecting the specific two reading lines 14 here is based on the following: under the national standard, the model of test mold 3 is used as the reference, and the qualified range interval of the diffusion degree of the cement mortar filled in the test mold 3.
[0036] If it exceeds this interval, it means that the fluidity of the cement mortar is qualified, and accurate reading can continue; if it does not exceed this interval, it means that the fluidity of the cement mortar is unqualified, and accurate reading is not necessary, and the next experiment can be directly performed, thereby improving the test efficiency.
[0037] The working principle of the above embodiment is as follows: the installation cylinder 4 at the bottom of the detection disc 1 is connected with the output end of the test rack 5, then the positioning disc cover 31 with the test mold 3 is sleeved on the transparent cover 2, then the test mold 3 is filled with cement mortar, after the cement mortar is treated, the positioning disc cover 31 with the test mold 3 is taken vertically upwards, then the up-down vibration mechanism in the test rack 5 is started, the fluidity of the cement mortar is tested, after the up-down vibration mechanism stops, the range diameter of the cement mortar flow can be obtained by observing the staff ruler 13 or the reading line 14.
[0038] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
