Detailed ways

In order to further explain the technical means and effects of the utility model to achieve the intended purpose of the utility model, the specific implementation, structure, features and effects of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. .

Please refer to FIG. 1 , the concrete slump measuring device according to the first embodiment of the present invention includes a test bench 1 and a slump cylinder 3 .

The test bench 1 includes a working platform 11 , a column 13 and a level 15 . The working platform 11 includes a top surface 111 with relatively high flatness, a bottom surface 112 opposite to the top surface 111 , and a side surface 113 connecting the top surface 111 and the bottom surface 112 . The top surface 111 is substantially rectangular, but not limited thereto. A spirit level 114 is provided on the top surface 111 for judging whether the top surface 111 is level. The top surface 111 is provided with a number of scale lines radially extending outward with a central point as the origin, and these scale lines divide 360 degrees into several equal parts. In this embodiment, the center point of the scale line is the center of the top surface 111 , but it is not limited to take the center point of the top surface 111 as the center point of the scale line. In this embodiment, the scale lines are four scale lines perpendicular to the four sides of the top surface 111. It can be understood that the number of scale lines is not limited to this, and it can also be 6, 8, 12, 24 etc. For the convenience of reading the scale, several concentric circles with the origin as the center are also drawn on the top surface 111 . Several adjustment feet 115 and several rollers 116 are installed on the bottom surface 112; the number of adjustment feet 115 is at least three. The height of the adjustment feet 115 can be adjusted according to the display results of the spirit level 114. When the spirit level 114 shows that the top surface 111 has an inclination, adjust the corresponding adjustment feet 115 to make the top surface 111 in a horizontal state; When it is in a horizontal state, it means that the height of the adjustment foot 115 has been adjusted in place and no further adjustment is required. Through the rollers 116, the test bench 1 can be moved to other positions conveniently and quickly, so as to measure concrete in different construction sites. A receiving groove (not shown) is provided on the side surface 113 along the length direction of the working platform 11 (that is, the extending direction of the level 15 in FIG. 1 ).

The column 13 is hinged to the side surface 113 , and the column 13 is perpendicular to the top surface 111 in its working state. Column 13 is provided with scale. An angle measuring instrument 131 is installed near the position of the column 13 on the top surface 111, and the angle between the column 13 and the top surface 111 is adjusted by the angle measuring instrument 131 to ensure that the concrete slump is measured (that is, the angle of the column 13 working state), the column 13 is perpendicular to the top surface 111 .

One end of the level bar 15 is fixed to the sliding clip 151, and the level bar 15 is perpendicular to the column 13 in its working state. A positioning knob 153 is disposed on the sliding clip 151 . The sliding clip 151 is sleeved on the column 13 and can drive the level 15 to slide along the column 13 or rotate around the column 13 . When the sliding clip 151 moves to a desired position with the level 15 , the opening of the sliding clip 151 is narrowed by turning the positioning knob 153 to fix the level 15 . When the concrete slump measuring device of the present invention is not needed, the upright column 13 and the level 15 can be rotated, and the upright column 13 and the level 15 can be accommodated together in the receiving groove of the working platform 11 . In addition, a scale may be further provided on the level bar 15 to measure the size of the slump cylinder 3 and the end face of the concrete.

The slump cylinder 3 is a trumpet-shaped conical cylinder with openings at both ends. In one embodiment of the present invention, the diameter of the upper opening of the slump cylinder 3 is 100 mm, the diameter of the lower opening is 200 mm, and the height is 300 mm.

When using the concrete slump measuring device of the present utility model to measure the slump of concrete, the slump cylinder 3 is placed at the center of the scale line on the top surface 111; then, concrete is poured into the slump cylinder 3 Then, the slump cylinder 3 is lifted, and the concrete slumps due to its own weight; in this process, the expanded diameter of the concrete slumped on the top surface 111 is the fluidity of the concrete, and the concrete passes through the top surface 111. The fluidity of the concrete can be obtained directly from the scale of the scale; move the level ruler 15 to make it contact with the highest point of the concrete after the collapse, and the height of the concrete after the collapse can be read through the scale on the column 3; then use the height of the collapse tube The slump of the concrete can be obtained by subtracting the height of the concrete after the collapse, which reduces the error caused by the combined reading of the horizontal reference and the ruler in the prior art. It can be understood that in other embodiments of the present utility model, the point corresponding to the height of the collapsed cylinder can be directly set as zero scale on the column 3, so that after the collapse, the scale value on the column 3 can be directly used to read The step of subtracting the height of the slump cylinder from the height of the concrete after slumping is not required to calculate the slump. Compared with the above-mentioned embodiment, this method is more intuitive and simplifies the steps of measuring the slump.

FIG. 2 is a schematic structural diagram of a measuring device for concrete slump in a second embodiment of the present invention. The structure of the test bench 1 in this embodiment is basically the same as that of the first embodiment, the difference lies in the combination of the column 13 and the working platform 11 . In the second embodiment, no receiving groove is provided on the working platform 11 . A base 17 is provided at the bottom of the column 13 . The lower surface of the base 17 is a horizontal plane. The column 13 is installed on the working platform 11 by placing the base 17 on the top surface 111 of the working platform 11 . In this embodiment, the base 17 and the working platform 11 are two separate structures, and the base 17 can be removed from the working platform 11 when the measuring device for concrete slump is not needed. In other aspects of the utility model In an embodiment, the base 17 may also be directly fixed to the working platform 11 by means of welding or the like.

In summary, the measuring device for concrete slump of the utility model utilizes its own working platform 11 to ensure that the measurement of slump in different occasions is carried out on the same platform, which reduces the difference between the mixing station and the construction site due to the test platform. The disputes caused by the different measurement data caused by inconsistency; in addition, the error caused by random measurement due to the lack of the test platform on the construction site is avoided; The angle measuring instrument 131 is combined together, and the measuring device for concrete slump of the present utility model can be moved by the rollers of the working platform 11, which avoids the inconvenience of carrying multiple measuring tool parts at the same time in the prior art In addition, the utility model combines the working platform 11, the column 13, the spirit level 15, the spirit level 114 and the angle measuring instrument 131 together, which can reduce the error generated when the measuring platform is built in the prior art, and improve the accuracy of the measurement Spend.
