Description
Technical Field
The invention relates to the technical field of constructional engineering concrete detection, in particular to a concrete slump detection device capable of being operated by one person.
Background
The existing concrete is one of the most common building materials, and the concrete is a mixture prepared by mixing a cementing material, aggregate, water and other admixtures according to a certain proportion. The building engineering can put forward the requirements for the performance of the concrete, and if the performance of the concrete does not meet the requirements, the quality of the construction process and the hardened concrete cannot be ensured, so that the performance of the concrete is one of the key contents for controlling the quality of the concrete.
In order to ensure the quality of concrete, slump test is one of the common test methods. The concrete slump is the height of the concrete slump under the action of self weight. Slump is a comprehensive index that can comprehensively characterize the consistency, cohesiveness and water retention of concrete. Slump is a standard for judging the workability of concrete construction in actual construction.
The conventional concrete slump cone fixing method comprises three common methods: one is that the slump cone is fixed by manual treading, the slump cone is placed on a non-absorbent rigid flat plate, one person treads foot pedals on two sides of the slump cone to fix the slump cone, the slump cone is kept at a fixed position when charging, and the other person carries out charging operation; after the loading is finished according to the standard of the concrete performance test method, the slump cone is stably lifted, and then the slump is measured. The detection method has the defects that the fixed slump cone is manually treaded, two persons are required to cooperate to complete the detection, the loading space is limited, and the loading is inconvenient. The other is that the electromagnet is fixed, and the slump measurement cylinder is fixed on the placing table through the electromagnet. The disadvantages are that the electromagnet is high in cost, needs a power supply, and is affected by rainy days when used outdoors. The other is mechanical fixing, and in the mechanical fixing mode in the prior art, some fixing parts are arranged at the pedal part of the slump cone, so that the coagulation is influenced to diffuse all around, and the precision is influenced. Some existing mechanisms are complex, resistance generated in the lifting process of the slump cone influences the concrete slump process, measurement results are influenced, and the requirement on operators is high.
Slump measurement methods mainly include two methods: the other method is that the measuring scale is arranged on one side and the leveling rod is arranged on the measuring scale for measurement, the leveling rod is required to move up and down during measurement, the measuring scale is an independent vertical rod and is poor in stability, and when the concrete slump is large, the slump cannot be accurately measured when the radius of the bottom of the concrete is larger than the length of the leveling rod. The other is that the slump cone is placed beside the cone concrete sample, a straight ruler facing the mixture is horizontally placed at the top of the cone, and the vertical distance from the bottom surface of the straight ruler to the highest point of the concrete is measured by a steel ruler, namely the slump of the concrete. The measurement method has the defects that the ruler and the additional steel ruler are used for combined measurement, the levelness of the horizontal ruler and the verticality of the steel ruler influence the accuracy of a measurement result, and the accuracy of the obtained slump result is poor.
Chinese patent publication No.: CN202021868269.9 discloses a concrete slump detection device for building engineering of convenient flattening, wherein the stability that a slump cone is fixed with the base is low, and single track measurement receives its inclination of unfixed factors such as weather to influence and can lead to the dipperstick not to reach the level and lead to the measuring result not accurate.
