Description

Slump measuring device

Technical Field

The utility model relates to the field of constructional engineering, in particular to a slump measuring device.

Background

Slump is a quantitative index used for measuring the plasticizing performance and pumpability of concrete and is used for judging whether construction can be normally performed. Slump is a measure and indicator of concrete workability, and slump tests are typically performed at construction sites and laboratories to determine the fluidity of the mix, with the aid of visual experience to assess cohesiveness and water retention. The construction quality management system of the construction industry in China is mature, and according to relevant specification, the slump of concrete must be detected strictly according to requirements in the concrete pouring process in the construction process of engineering projects.

At present, a trumpet-shaped slump barrel with the upper opening diameter of 100mm, the lower opening diameter of 200mm and the height of 300mm is generally used for filling concrete for three times, a rammer is used for uniformly beating 25 from outside to inside along the barrel wall after each filling, the rammer is smoothed after ramming, then the slump barrel is pulled up, the slump phenomenon is generated due to the dead weight of the concrete, and the highest height of the concrete after slump is subtracted by the barrel height (300 mm), namely the slump. When the height of the highest position of the concrete is measured, one end of a steel bar rod is fixed on the upper edge of the slump barrel, and the other end of the steel bar rod is suspended on the upper part of the concrete to be measured. The distance from the highest position of the concrete to be measured to the steel bar is measured by a steel tape, and the distance is the slump value measured. However, the use of the above measurement method is extremely prone to errors: the slump barrel is directly placed on the ground, the ground is uneven, and slight inclination of the slump barrel is easy to cause; the steel tape combined with the steel bar rod cannot be accurately fixed at the highest position of the concrete after slump; the manual fixing of the steel bar rod cannot ensure the level of the upper edge of the slump barrel, and the measuring of the steel tape cannot be ensured to be vertical to the steel bar rod.

Therefore, how to reduce the measurement error and recycle the concrete used in the measurement process is a technical problem that needs to be solved by those skilled in the art.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1, the slump measuring apparatus disclosed by the utility model comprises a base 100, a first rod member 200, a fixing member 300 and a second rod member 400, wherein the first rod member 200 is vertically arranged on the base 100, the fixing member 300 is sleeved on the first rod member 200, the second rod member 400 is connected with the fixing member 300, and the first rod member 200 is vertical to the second rod member 400; the fixing member 300 rotates the second rod 400 around the first rod 200 and moves along the first rod 200 so that the second rod 400 reaches the highest position of the concrete.

The second rod 400 is perpendicular to the first rod 200, i.e., the second rod 400 is parallel to the base 100. During the measurement, the rotation and movement of the second rod 400 along the first rod is achieved by the fixing member 300 so that the second rod 400 reaches the highest place of the concrete.

In this way, the height of the highest portion of the concrete is converted into the height of the second rod 400, and the height of the second rod 400 is more easily measured. The height of the highest position of the concrete is subtracted from the height (300 mm) of the slump barrel, or the height difference between the slump barrel and the highest position of the concrete is directly obtained, so that the slump of the concrete can be obtained. The slump measuring device provided by the utility model is used for measuring, is simple to operate, can effectively reduce measuring errors, is operated on the base 100 during measuring, is not in direct contact with the ground, and can recycle the concrete used in the measuring process.

To avoid that the concrete splashes to other places during the measurement, a baffle is provided on the base 100, the presence of which limits the flow range of the concrete on the base 100. And the baffle can be detached, so that the collection of concrete is more convenient by detaching the baffle after the measurement is finished.

In one embodiment of the present utility model, a slump barrel is provided at the base 100, and the slump barrel has a trumpet shape with an upper opening diameter of 100mm, a lower opening diameter of 200mm, and a height of 300mm. The concrete is poured into the slump barrel and then tamped, then the slump barrel is vertically pulled up, the concrete is not touched in the process of pulling up the slump barrel so as not to influence the measured data, the slump phenomenon is generated due to the dead weight of the concrete, and the highest position of the concrete after slump is subtracted by the height of the barrel (300 mm), namely the slump.

It should be noted that, since a series of operations are performed on the base 100 during measurement, the slump barrel is directly placed on the base 100, and in order to ensure accuracy of measurement results, the base 100 is set to be a flat plane.

In order to optimize the technical scheme, the lifting structure is arranged on the base 100 and is connected with the slump barrel to drive the slump barrel to be vertically far away from or close to the base 100, so that the damage to concrete in the process of pulling up the slump barrel is avoided.

When the second rod 400 is aligned with the highest position of the concrete, the first rod 200 is perpendicular to the base 100, the second rod 400 is perpendicular to the first rod 200, and the second rod 400 is flush with the highest position of the concrete, so that the height of the highest position of the concrete is converted into the height of the second rod 400. In order to further reduce errors in the measuring process and improve the measuring precision, the second rod piece 400 is arranged to be flat steel, so that the second rod piece 400 can be more conveniently searched and aligned to the highest position of the concrete.

Further, scale marks are provided on the first rod 200, and the position of the second rod 400 on the first rod 200 can be obtained quickly by directly reading the scale marks. For more convenient measurement, the height of the second lever 400 is set to be identical to the height of the lower end of the fixing member 300. If the zero scale mark of the scale mark is disposed at the end of the first rod 200 connected to the base 100, the height of the highest position of the concrete can be obtained by reading the value on the first rod 200 corresponding to the lower end of the fixing member 300, and the slump of the concrete can be obtained by subtracting the height of the highest position of the concrete from the height of the slump barrel (300 mm).

To make the measurement easier, in an embodiment of the present utility model, the maximum scale of the scale mark is set to 300mm, which coincides with the height of the slump barrel.

The maximum scale based on the scale mark is set to 300mm, the zero scale mark of the scale mark is set at one end of the first rod piece 200 which is not connected with the base 100, calculation is not needed, and the slump of concrete can be obtained by directly reading the value corresponding to the lower end of the fixing piece 300.

During the measurement, it is necessary to move the fixing member 300 up and down along the first rod 200 to change the height of the second rod 400 with respect to the base 100, and to rotate the second rod 400 along the first rod 200 during this process to determine the highest position of the concrete. As shown in fig. 2, in an embodiment of the present utility model, a driving screw 500 is provided, the driving screw 500 is rotatably supported on the base 100, the driving screw 500 is parallel to the first rod 200, and the fixing member 300 is provided with a screw hole in threaded engagement with the driving screw 500.

When the second rod member 400400 approaches the highest position of the concrete, the driving screw 500 is rotated, the screw hole of the fixing member 300 is screw-engaged with the driving screw 500, and the fixing member 300 is moved up and down along the first rod member 200 by the driving screw 500. The driving screw rod 500 is rotated, so that the rotary motion of the driving screw rod 500 is converted into the linear motion of the fixing piece 300, the position of the fixing piece 300 on the first rod piece 200 can be slowly adjusted, the second rod piece 400 is slowly lowered, and the situation that the shape of concrete is damaged due to overlarge movement amplitude when the second rod piece 400 is close to the concrete is avoided.

In order to optimize the above scheme, a locking jackscrew is provided, the fixing member 300 is provided with a locking screw hole penetrating through the wall thickness of the fixing member 300 and pointing to the first rod member 200, the locking jackscrew is in threaded fit with the locking screw hole, and one end of the locking jackscrew is used for propping up with the outer wall of the first rod member 200. When the second rod 400 is aligned to the highest position of the concrete, the second rod 400 needs to be fixed to facilitate reading, and the locking jackscrew is rotated to enable the locking jackscrew to be in threaded fit with the locking screw hole until one end of the locking jackscrew abuts against the outer wall of the first rod 200, and the position of the second rod 400 is fixed.
