Concrete collapsed slump detection apparatus used for building construction

Abstract

The invention discloses a concrete slump detection device for building construction, which includes a support, and the upper end surface of the support is rotationally symmetrically connected with two screw rods. The slump bucket is placed on the support, and concrete is poured into the slump bucket. At this time, the first conductive block is in contact with the second conductive block, and the first electromagnet and the second electromagnet are connected through the external power supply. Electricity, the first electromagnet and the second electromagnet attract each other. When the slump bucket needs to be pulled out, the rotating rod is manually rotated to make the slider rise on the screw rod, thus ensuring the vertical upward movement of the slump bucket. , the first conductance block is separated from the second conductance block, the brush plate vibrates under the action of the spring, the concrete on the upper end of the slump bucket is cleaned, and the error caused by the inability to pull out the slump bucket vertically is avoided.

Description

technical field [0001] The invention relates to the field of construction, in particular to a concrete slump detection device for construction. Background technique [0002] The slump is the method and index for measuring the workability of concrete. In construction sites and laboratories, the slump test is usually used to measure the fluidity of the mixture, and it is supplemented by visual experience to evaluate the cohesion and water retention. The slump is a quantitative index to measure its level, which is used to judge whether the construction can proceed normally. The detection of slump in the prior art is to use the slump bucket to fill the concrete and take it out at last. When taking out the slump bucket in this method, since the slump bucket cannot be taken out vertically, the slump will be lowered. There are errors in the detection, and the excess concrete overflowing from the upper end of the slump bucket cannot be cleaned in time. Contents of the invention ...
