Description

Improvement type concrete fluidity testing arrangement

Technical Field

The utility model relates to a building materials test instrument's technical field especially relates to an improvement type concrete fluidity testing arrangement.

Background

The concrete is the building material with the largest consumption and the widest application in modern building engineering, and in order to test the fluidity of concrete mixtures, the slump cone is widely adopted by all countries in the world all the time due to the simple device and clear index. The existing concrete slump cone consists of a slump cone body, a pedal and a handle.

The existing slump cone is inconvenient to test the fluidity of the concrete mixture. When the testing device is used, at least two persons are needed to finish the testing work, one person steps on the pedal plate of the slump cone by two feet to fix the slump cone on the testing bottom plate, and the other person carries out loading. And the personnel who step on the slump section of thick bamboo must hand and foot simultaneously, when filling concrete mixture sample that mobility is big, if carelessly a bit, cement paste spills inconvenient the processing, in whole operation process, must make the slump section of thick bamboo stabilize on the bottom plate motionless. Before mentioning the slump section of thick bamboo, can not guarantee that the slump section of thick bamboo is in the level, also be difficult to control the straightness that hangs down and the speed of lifting of the slump section of thick bamboo when lifting, make concrete mixture sample receive the horizontal torsion effect and produce the slope when drooping, it is inhomogeneous to mention the speed, brings very big error to the test result, concrete mixture sample after the test also does not benefit to centralized processing. In addition, the operator needs to measure the slump by using a ruler, and subjective judgment errors exist. In conclusion, the existing concrete slump test method is simple in device, but inconvenient to operate, low in efficiency, not easy to clean and inaccurate in result.

For solving prior art's shortcoming and not enough, provide an improvement type concrete fluidity testing arrangement, make the operation process simplification, reduce unnecessary survey error, concrete mixture sample is easily centralized processing.

For realizing the utility model aims at providing an improvement type concrete fluidity testing arrangement, be in including chassis and setting support on the chassis, it is provided with the slide bar to slide on the support, fixedly connected with slump section of thick bamboo, lifter on the slide bar, be equipped with the screw hole on the lifter, the support top is equipped with motor, controller, battery, the controller is used for the drive motor work, the motor output is equipped with the screw rod, screw rod top-down passes the screw hole that sets up on the lifter, the screw rod bottom is equipped with infrared altimeter, be equipped with spirit level, leveling bolt on the chassis, the chassis is detachable in the below of a slump section of thick bamboo and is connected with the clearance board.

As a further improvement of the scheme, the concentric circle scale is arranged at the center of the base plate, the cleaning plate is made of transparent materials, and the concentric circle scale can be seen through the cleaning plate.

As a further improvement of the scheme, an infrared altimeter display is arranged on the controller, and the reading can be timely read after the measurement is finished.

As a further improvement of the scheme, four leveling bolts are symmetrically distributed on the chassis.

As a further improvement of the scheme, a clamping block is arranged on the chassis and used for fixing the position of the cleaning plate, and an opening is formed in the cleaning plate corresponding to the clamping block.

The utility model has the advantages that:

compared with the prior art, the utility model provides a pair of improvement type concrete fluidity testing arrangement, spirit level and leveling nut established through the chassis can make the device be in horizontal position, through the motor, the screw rod, the slide bar, the lifter, can guarantee simultaneously that slump section of thick bamboo promotes and descends at the uniform velocity in the vertical direction, can accurately measure concrete slump through the built-in infrared altimeter of screw rod, the display reacts the reading in time, the concrete divergence can be read out through the concentric circles scale on the chassis, can directly remove the clearance board after the survey, centralized processing concrete mix sample.
