Description

Technical Field

[0001] This utility model relates to the field of testing equipment, and more specifically, to a plate for measuring the flowability of cement-based grouting materials. Background Technology

[0002] In the design and formulation stage of cement-based grouting materials, a large number of experiments are required to determine the final production mix ratio. During the experiment, the flowability of the truncated cone mold needs to be tested frequently. According to Appendix A of GB / T50448-2015 "Technical Specification for Application of Cement-based Grouting Materials", the test steps of the test method for basic performance of cement-based grouting materials are as follows: The mixing pot, mixing blades, glass plate and inner wall of the truncated cone mold should be pre-wetted; after the mixed grouting material is poured into the truncated cone mold, the grout should be flush with the top of the truncated cone mold; after lifting the truncated cone mold, the grouting material should be allowed to flow freely without disturbance until it stops. The maximum diffusion diameter of the bottom surface and the diameter in the direction perpendicular to it should be measured with calipers, and the average value should be calculated as the initial value of flowability. The test result should be accurate to 1 mm; the initial value test should be completed within 6 minutes; after the initial value measurement is completed, the grouting material on the glass plate should be quickly poured into the mixing pot, and the mixing pot should be covered with a damp cloth; after the initial value measurement is completed, the above steps should be repeated for 30 minutes to measure the flowability value as the 30-minute retention value, and the data should be recorded.

[0003] Most existing measuring plates do not have windproof measures. When measuring in some external environments, wind may disturb the flow of grouting material, causing deviations in the flow path of the grouting material and affecting the accuracy of the measurement results. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a plate for measuring the flowability of cement-based grouting materials, comprising: a transparent plate, wherein a graduated ring is provided on the upper surface of the transparent plate, and the center of the graduated ring coincides with the center of the transparent plate.

[0005] The graduation lines are located on the graduation ring;

[0006] A transparent cover is used to cover the transparent plate, and the transparent cover is detachably connected to the transparent plate.

[0007] Optionally, it also includes a rotating plate, the bottom ends of which are rotatably connected to the upper surface of the transparent cover, and the bottom ends of which are on the same circular trajectory, which coincides with the center of the transparent plate.

[0008] Optionally, it also includes a leveling mechanism, of which at least three are provided, and each leveling mechanism includes a bolt and a base plate. The periphery of the transparent plate is provided with a threaded hole, which is threadedly connected to the bolt. The bottom end of the bolt is movably connected to the base plate.

[0009] Optionally, it also includes a level bubble, which is disposed on the upper surface of the transparent plate, and multiple level bubbles are provided, with at least one level bubble disposed near the leveling mechanism.

[0010] Optionally, a plurality of positioning shafts are fixedly connected to the periphery of one end face of the transparent cover, and an insertion hole is provided on the upper surface of the transparent plate, and the positioning shaft is used to be inserted into the corresponding insertion hole.

[0011] Optionally, a buckle is provided around one end face of the transparent cover, and a fastening position is provided on the upper surface of the transparent plate, the buckle being used to engage with the fastening position.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By placing the truncated cone mold at the center of the transparent plate, the mixed grout is slowly poured into the mold, ensuring the grout is flush with the top of the mold. After lifting the mold, the transparent cover is quickly placed over the transparent plate, allowing the grout to flow freely without disturbance until it stops. The transparent plate acts as a windbreak, preventing wind from blowing the grout and causing deviations in the flow path, thus improving the accuracy of subsequent measurement data. The position of the grout flow is read through the scale lines on the scale ring, and the average value is calculated as the initial value of the flowability. After the test is completed, the transparent plate is cleaned. Attached Figure Description

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this specification, "multiple" refers to two or more.

[0021] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.

[0022] Combination Figure 1-3 As shown, this utility model embodiment provides a cement-based grouting material flowability measuring plate, including: a transparent plate 1, a scale ring 5 on the upper surface of the transparent plate 1, the center of the scale ring 5 coinciding with the center of the transparent plate 1, scale lines 6 on the scale ring 5; and a transparent cover 7 for covering the transparent plate 1, and the transparent cover 7 is detachably connected to the transparent plate 1.

[0023] In this embodiment, the truncated cone mold is placed at the center of the transparent plate 1, and the mixed grout is slowly poured into the truncated cone mold. The grout should be flush with the top of the truncated cone mold. Then, after lifting the truncated cone mold, the transparent cover 7 is quickly placed on the transparent plate 1, allowing the grout to flow freely without disturbance until it stops. The transparent plate 1 acts as a windproof barrier, preventing the grout from being blown by the wind and causing deviations in the flow path, thus improving the accuracy of subsequent measurement data. The position of the grout flow is read through the scale line 6 on the scale ring 5, and the average value is calculated as the initial value of the flowability. After the test is completed, the transparent plate 1 is cleaned.

[0024] In one embodiment of this utility model, a rotating plate 2 is also included. The bottom ends of multiple rotating plates 2 are rotatably connected to the upper surface of the transparent cover 7, and the bottom ends of multiple rotating plates 2 are on the same circular trajectory, which coincides with the center of the transparent plate 1.

[0025] In this embodiment, after the truncated cone mold is placed at the center of the transparent plate 1, the tops of the multiple rotating plates 2 are rotated to abut against the outer circumferential surface of the truncated cone mold. Since the bottoms of the rotating plates 2 are on the same circular trajectory, the rotating plates 2 press down on the outer wall of the truncated cone mold with their own weight, pushing the truncated cone mold to slide on the transparent plate 1 until the multiple rotating plates 2 are in a balanced state. At this time, the center of the truncated cone mold and the center of the transparent plate 1 are on the same vertical line, which improves the coaxiality of the truncated cone mold and thus improves the accuracy of the test data.

[0026] In another embodiment of this utility model, a leveling mechanism 3 is also included. At least three leveling mechanisms 3 are provided, and each leveling mechanism 3 includes a bolt 31 and a base plate 32. A threaded hole 11 is provided around the periphery of the transparent plate 1. The threaded hole 11 is threadedly connected to the bolt 31, and the bottom end of the bolt 31 is movably connected to the base plate 32.

[0027] Specifically, the bottom end of the bolt 31 can be movably connected to the base plate 32 by setting a ball head seat on the base plate 32. The bottom end of the bolt 31 is ball-shaped and is fitted into the ball head seat, so that the base plate 32 can be tilted relative to the bolt 31 to a certain extent, so that the bolt 31 will not cause motion interference when rotating.

[0028] In this embodiment, three leveling mechanisms 3 are evenly distributed on the lower surface of the transparent plate 1. The bolt 31 is threadedly connected to the threaded hole 11 on the transparent plate 1. Thus, when the bolt 31 is rotated, the bolt 31 can move vertically relative to the threaded hole 11. The bolt 31 is rotatably connected to the base plate 32, thereby adjusting the tilt of the transparent plate 1 on the corresponding side. Then, the transparent plate 1 is adjusted to a horizontal state by adjusting the three leveling mechanisms 3.

[0029] In other embodiments of this utility model, a horizontal bubble 4 is also included. The horizontal bubble 4 is disposed on the upper surface of the transparent plate 1, and multiple horizontal bubbles 4 are provided, with at least one horizontal bubble 4 provided near the leveling mechanism 3.

[0030] In this embodiment, the level bubble 4 can display the horizontal state of the transparent plate 1, and the level bubble 4 is located on the transparent plate 1 near each leveling mechanism 3. Thus, when the transparent plate 1 is leveled by the leveling mechanism 3, the level bubble 4 in the vicinity can be viewed at the same time, which makes it convenient for the staff to level and view at the same time, and improves the convenience of the actual operation process.

[0031] In one embodiment of this utility model, a plurality of positioning shafts 71 are fixedly connected to the periphery of one end face of the transparent cover 7, and an insertion hole is provided on the upper surface of the transparent plate 1, and the positioning shafts 71 are used to be inserted into the corresponding insertion hole.

[0032] In this embodiment, multiple positioning shafts 71 can be fixed to one end face periphery of the transparent cover 7 by means of threaded connection. The positioning shafts 71 can also be formed by extending from one end face periphery of the transparent cover 7. Insertion holes are opened on the upper surface of the transparent plate 1 so that multiple positioning shafts 71 can be inserted into the corresponding insertion holes, thereby realizing quick assembly and disassembly of the transparent cover 7 and the transparent plate 1.

[0033] In another embodiment of this utility model, a buckle is provided around one end face of the transparent cover 7, and a buckle is provided on the upper surface of the transparent plate 1. The buckle is used to engage with the buckle.

[0034] In this embodiment, at least two buckles are provided around one end face of the transparent cover 7, and a corresponding buckle is provided on the upper surface of the transparent plate 1 to match the buckles, so that the transparent cover 7 can be snapped into the transparent plate 1, thereby improving the stability of the transparent cover 7 after it covers the transparent plate 1.

[0035] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
