Description

A concrete slump meter

technical field

The utility model relates to the technical field of concrete detection equipment, in particular to a concrete slump meter.

Background technique

Slump mainly refers to the plasticizing performance and pumpability of concrete, which is a quantitative index to measure its degree (plasticization and pumpability), and is used to judge whether the construction can proceed normally. Concrete slump is mainly affected by changes in gradation, water content, and weighing deviation of horizontal devices. The amount of admixtures that is easily overlooked is also the temperature of cement. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including water retention, fluidity and cohesion of concrete. Workability means that the concrete mixture is easy to operate (mixing, transportation, pouring, tamping), and can obtain uniform and dense concrete properties. Workability is a comprehensive technical property, including the definitions of water retention, fluidity and cohesion. The workability is mainly affected by water consumption, water-cement ratio, sand rate, cement type, aggregate condition, time and temperature, admixture and other aspects. the

At present, a slump meter is usually used to detect the slump of concrete. The existing slump meter usually has no connection between the slump barrel and the bottom plate. It overflows from the gap between the bottom plate and the bottom of the slump bucket, thus affecting the test results. In the existing market, bolts are also used to fix the bottom plate and the slump bucket, but after repeated tests, the bolts and nuts will be stuck by concrete. together so that the slump bucket cannot be disassembled.

Contents of the invention

The technical problem to be solved by the utility model is to provide a concrete slump meter. The utility model firstly effectively solves the problem that there is no connection between the traditional slump bucket and the bottom plate, and the concrete will flow from the gap between the bottom plate and the bottom of the slump bucket. The problem of overflow is solved, and the problem of concrete bonding between the bolt and the nut is effectively solved by the existing bolt fixing.

The utility model is realized through the following technical solutions:

A concrete slump meter, comprising a base plate (1), on which a measuring scale (2), a flat ruler (3) and a slump bucket (4) are arranged, characterized in that: the slump The barrel (4) is engaged with the upper surface of the bottom plate (1) in a movable manner.

The further technical improvement scheme of the utility model is:

At least three clamping devices (5) are arranged on the bottom plate (1), and the clamping devices (5) are equiangularly distributed on the same circumference, and the bottom end of the slump bucket (4) is provided with a lower extension boss ( 41), the lower extension boss (41) is provided with bayonet sockets (411), the number of bayonet sockets (411) is matched with the snap-in device (5), and the outer peripheral surface of the lower extension boss (41) is provided with a ring clip Groove (412).

The further technical improvement scheme of the utility model is:

The clamping device (5) includes a screw (51), an elastic member (52), and a chuck (53). The clamping device (5) is screwed to the bottom plate (1) through a connecting rod (6), and the screw (51) An elastic member (52) is arranged between the chuck head (53).

The further technical improvement scheme of the utility model is:

The upper end of the slump barrel (4) is also provided with an upper extension boss (42).

The further technical improvement scheme of the utility model is:

The slump bucket (4) is made of metal material, and the thickness of the bucket body is at least 3 cm.

The further technical improvement scheme of the utility model is:

The elastic component (52) is a spring or an elastic rubber block.

Compared with the prior art, the utility model has obvious advantages,

1. The slump barrel and the bottom plate of the utility model are connected by rotation. When the tamping rod is in the process of compacting the concrete in the barrel, it is difficult for the concrete to overflow from the gap between the bottom plate and the bottom of the slump barrel, which improves the test structure. accuracy.

2. The slump barrel of the utility model is equipped with an upper extension boss, which not only can be used as a handle, but also increases the rigidity of the slump barrel body without deformation, and effectively prevents slurry leakage.
