Description

Slump detection device

Technical Field

The utility model relates to a concrete detection device, in particular to slump detection device.

Background

Slump is an index for detecting the workability of concrete, and whether construction can be normally carried out or not is judged mainly through the fluidity, cohesiveness and water-retaining property of the concrete. The slump is measured by the detector generally using a slump cone, which is a trumpet-shaped cone with a top end opening smaller than a bottom end opening, and is provided with two pedals and two handles on the outer side wall, and is usually used together with a funnel and a tamper.

When the slump is detected, firstly, the slump cone is placed on a flat ground, and a detector steps on two pedals respectively with two feet to stabilize the pedals on the ground; and then placing the funnel at the top end of the slump cone, and pouring concrete into the slump cone through the funnel. In the process of pouring concrete, pouring is carried out for three times, wherein the height of the slump cone is one third of that of the slump cone, and the concrete in the slump cone needs to be tamped by using a tamping rod after pouring each time. After the last pouring and tamping are finished, the funnel is removed, and redundant concrete at the top end of the slump cone is removed and leveled; and finally, the detector presses the two handles with both hands, leaves the two pedals with both feet, and then slowly and vertically lifts the slump cone upwards, so that the concrete in the slump cone can collapse under the action of the gravity of the concrete, then the highest point of the slump cone is measured, and the slump is obtained by subtracting the height of the concrete from the height of the slump cone.

When the slump detection device is used for remeasurement, two rulers are required to be vertically crossed and matched for use, wherein one ruler is used for marking the height of the slump cone, and the other ruler is used for measuring the height difference between the top end of the concrete and the top end of the slump cone. The perpendicularity between the two rulers is difficult to ensure by the measuring mode, so that the measuring precision is low; and the two rulers are separated from the slump cone, so that the phenomenon of loss can be frequently caused.
