the vibration table 300 is connected with the capacity cylinder 200 to drive the mortar sample 11 in the capacity cylinder 200 to vibrate, so that the consistency is determined according to the sinking depth of the weight 100 and the slurry outlet condition of the surface of the weight 100.

The concrete mortar consistency detector 10 of the present embodiment comprises a weight 100, a volume cylinder 200 and a vibration table 300, wherein the volume cylinder 200 is used for receiving and collecting a cement concrete sample 11 for test use. The pressing plane at the bottom of the weight 100 can be directly matched with the cement concrete sample 11 in the capacity cylinder 200, the surface of the cement concrete mortar sample 11 is pressed by the pressing plane of the weight 100, and the consistency is determined by the sinking depth of the weight 100 and the slurry outlet condition of the surface of the weight 100. The whole test process does not need complicated other structures to participate, and is suitable for operation by a single person. Compared with the testing steps in the prior art, the method only needs to place the weight 100 on the surface of the mortar sample 11 and observe the subsidence and the slurry outlet of the mortar, so that the operation process is simplified, the time and the labor are saved correspondingly, and the testing efficiency is improved. In summary, such a concrete mortar consistency detector 10 has the characteristics of simple structure, convenient use, time and labor saving and high testing efficiency.

With continued reference to fig. 1-4, additional structural details of the concrete mortar consistency detector 10 are known.

As can be seen from the figures, the weight 100 is a solid cylindrical structure. The cylinder 200 is also a cylindrical barrel. And the diameter of the capacity cylinder 200 is slightly larger than the diameter of the weight 100.

Further, in the present embodiment of the present utility model, the weight 100 and the measuring cylinder 200 are concentrically arranged cylinders. Thus, the centering of the weight 100 and the capacity cylinder 200 can be ensured, and the process of pressing the mortar by the weight 100 can be stably and conveniently sunk.

Regarding the arrangement manner of the weight 100 and the measuring cylinder 200, those skilled in the art should be able to reasonably select and design according to actual requirements, and there is no specific limitation herein, and the materials of the weight 100 and the measuring cylinder 200 are exemplified as slightly eccentric, so as to be suitable for different actual situations, which are only examples herein, and not limitations.

The weight 100 can be guaranteed, and the mortar in the capacity cylinder 200 can be extruded by the mortar mixer with larger volume and weight under the condition of the same bottom area, so that the consistency test effect is guaranteed.

Alternatively, in this embodiment, both the weight 100 and the volume cylinder 200 are made of metal. The metal weight 100 and the measuring cylinder 200 have a heavier weight, and thus have the advantages of a more stable center of gravity and a better smoothness. Specifically, the weight 100 and the measuring cylinder 200 are made of stainless steel.

It should be noted that, regarding the materials of the weight 100 and the measuring cylinder 200, those skilled in the art should be able to reasonably select and design according to the actual requirements, and the materials of the weight 100 and the measuring cylinder 200 are not limited herein, and examples are cast iron, copper, galvanized stainless steel, aluminum, etc. to be suitable for different practical situations, and are only examples herein without limitation. Further, the weight 100 and the capacity cylinder 200 may be made of different materials.

In this embodiment, the capacity cylinder 200 accommodates mortar in an amount of 1/5 to 1/4 of the weight 100.

Further, in the present embodiment of the present utility model, the operating frequency of the vibration table 300 is 50hz±3Hz; and the vibration table 300 has an empty load amplitude of 0.5mm + -0.1 mm when it contains the capacity cylinder 200. Through multiple researches and experiments by the technical inventor, when the working frequency is about 50Hz, components such as particles in the mortar can be uniformly mixed, so that the subsequent sedimentation and smooth slurry discharge of the weight 100 are facilitated. And the empty load amplitude of the volumetric cylinder 200 is controlled to be about 0.5mm, so that the stability and the reliability of the whole shaking table 300 and the volumetric cylinder 200 in the test process can be ensured, and the whole structure is ensured to have a better stable effect.

Regarding the specific mode of the frequency and amplitude of the vibration table 300, those skilled in the art should be able to make reasonable selections and designs according to the actual needs, without specific limitation, to adapt to different practical situations, which are only examples and are not limiting.

Alternatively, as shown in fig. 1 and 2, in the present embodiment of the present utility model, a plurality of identification marks 110 are provided on the weight 100, and the plurality of identification marks 110 are arranged in the height direction. Specifically, the weight 100 is equally divided into 4 small cell marks which are used as marks for sinking the weight 100; after the shaking table 300 is started to vibrate for a preset time, the sinking degree of the weight 100 in 4 directions is recorded, and the average value is taken as a sinking value.

It should be understood that the number of the mark graduation marks on the weight 100 may be plural, so long as the mark graduation marks 110 can identify the sinking depth of the weight 100, which is not limited herein.

Specifically, in the present embodiment of the present utility model, the adjacent plurality of marking graduation marks 110 are equidistantly arranged in the height direction.

With respect to the specific arrangement of the plurality of marking graduations 110, those skilled in the art should be able to reasonably select and design according to the actual needs without being limited thereto, and the plurality of marking graduations 110 are arranged in an increasing or decreasing manner to be suitable for different practical situations, which are merely examples and not limiting.

Referring to fig. 3 and 4, in the present embodiment of the utility model, a plurality of transmission mechanisms 400 are further included, wherein one end of each transmission mechanism 400 is connected to the vibration table 300, and the other end is connected to the middle portion of the volumetric cylinder 200 to uniformly transmit the vibration of the vibration table 300 to the cylinder body of the volumetric cylinder 200.

The transmission mechanism 400 here serves to uniformly transmit the vibration of the vibration table 300 to the entire body of the capacity cylinder 200, not only to the lower portion of the capacity cylinder 200. Specifically, the transmission mechanism 400 is uniformly arranged in the circumferential direction of the capacity cylinder 200. By way of example, a transmission 400 is provided, the transmission 400 comprising a pole 410 mounted on the oscillating table 300, and a cross bar 420 connected to the pole 410, the end of the cross bar 420 remote from the pole 410 being connected to a transmission 430.

Alternatively, the transmission 430 is located at a central position of the capacity and extends slightly toward the top of the capacity cylinder 200. Alternatively, the transmission part 430 is made of rubber, and the vibration force can be more uniformly transmitted to the entire body of the measuring cylinder 200 by using its structural elasticity.

Regarding the specific structure of the transmission mechanism 400, those skilled in the art should be able to make reasonable selections and designs according to actual needs, and there is no specific limitation in this regard, as long as the vibration of the vibration table 300 can be uniformly transmitted to all the barrels, so as to be suitable for different practical situations, which are only examples and not limitations.

At present, the method for measuring the consistency of the dry and hard concrete at home and abroad mostly adopts a Marshall compaction method, a geotechnical compaction method, a diving table method and a VC value improvement method, so that the VC value improvement method is most applied.

The traditional concrete wibro consistometer vibration mode is an upward and downward vibration mode), the vibration mode of the construction machine is an upward and upward vibration mode, the two modes have the mechanism difference, and the vibration frequency and the vibration amplitude of the concrete wibro consistometer are not adjustable.

The concrete wibro consistometer is therefore not able to simulate well the vibration conditions of a construction machine, such as a paver screed or road roller, to determine the actual liquefaction time (i.e. consistency), thus causing the problem of inaccurate results of the tests of existing consistometers.

Accordingly, the transmission mechanism 400 of the scheme can uniformly transmit vibration force to the cylinder body through the transmission mechanism 400 so as to simulate the condition of upper vibration (upper compaction and upper vibration) of the construction machinery, and ensure the stability of mortar vibration test.

Further, in order to ensure the upper vibration effect, an annular table 510 is provided on the top surface of the vibration table 300, a sliding film 520 is provided in the annular table 510, and the capacity cylinder 200 is placed on the sliding film 520, so that the capacity cylinder 200 and the surface of the vibration table 300 form a lubrication contact manner. Optionally, the sliding film 520 may be a lubricant, a graphite disk, or the like.

Regarding the specific structure of the annular table 510 and the sliding film 520, those skilled in the art should be able to make reasonable selections and designs according to the actual needs, and there is no specific limitation herein, as long as the shaking table 300 can be kept in sliding contact with the measuring cylinder 200, so as to be suitable for different practical situations, which are only examples and not limitations herein.

In the present embodiment of the utility model, the transmission mechanism 400 is at least symmetrically disposed in the radial direction of the volume cylinder 200. This ensures that vibration of the vibration table 300 can uniformly transfer the shaft of the volumetric cylinder 200.

When in use, the concrete consistency tester comprises a weight 100, a volume cylinder 200 and a vibration table 300 from top to bottom in sequence, and the weight 100 is partially positioned in the volume cylinder 200.

The weight 100 is a cylinder, and is made of metal, and the parameters are as follows: the diameter of the cross section is 136mm, the height of the cylinder is 260mm, and the weight is 13.3kg.

The volumetric cylinder 200 is a hollow cylinder, made of metal, and has the following parameters: the diameter of the inner cross section is 140mm, and the inner height is 200mm.

The parameters of the vibration table 300 are: the working frequency is 50Hz + -3 Hz, and the empty load amplitude of the volumetric cylinder 200 is 0.5mm + -0.1 mm.

The process of testing the consistency of the dry and hard cement concrete by using the tester is as follows:

(1) the inner wall of the measuring cylinder 200 and the upper and lower surfaces of the shaking table 300 were rubbed with wet cloth before the test.

(2) A representative cement concrete sample 11 of uniform mass was taken at about 2.5kg.

(3) The sample 11 is lightly loaded into the cylinder 200 by a tool such as a ladle, and the sample is prevented from falling down freely during loading so as to prevent the sample 11 from segregating, and finally the surface is smoothed by a metal plating knife.

(4) As shown in fig. 2, a weight 100 (iron block) 1 is placed in a measuring cylinder 200, 4 mark graduation marks 110 are equally divided on the iron block, and an initial height H of the iron block is recorded.

(5) The shaking table 300 was started, and the stopwatch was pressed at the same time, and after the shaking table 300 was started for 20 seconds, the degree of sinking of the iron pieces in 4 directions was recorded, and an average value was obtained.

(6) The iron plate was lifted to view surface slurry and scored.

As can be seen from the above embodiments, the technical solution of the present utility model realizes the simulation of vibration industry and mining in site construction by the parameter design of the weight 100, the volumetric cylinder 200 and the vibration table 300, so that the consistency of the dry and hard concrete can be determined.
