Technical Field

[0001] The utility model belongs to the technical field of concrete detection, and particularly relates to a concrete slump detector. Background Art

[0002] Concrete refers to a general term for engineering composite materials in which aggregate is cemented into a whole by a binder. Generally speaking, the term "concrete" refers to cement concrete, also known as ordinary concrete, which uses cement as the binder, sand and stone as the aggregate, and is mixed with water in a certain proportion and stirred.

[0003] The slump of concrete refers to the workability of concrete. Specifically, it ensures the normal progress of construction, including the water retention, fluidity and cohesion of concrete. The main factors affecting the slump of concrete include gradation change, water content, weighing deviation of weighing instrument, dosage of admixture and temperature of cement, etc. The slump is measured by a quantitative index to measure its degree, and is used to judge whether the construction can proceed normally. If the slump is too small, it will affect the construction (such as pumped concrete or concrete vibration); if it is too large, it is easy to segregate (cement slurry loss), reducing the strength of concrete. Therefore, the slump measurement is particularly important.

[0004] However, the traditional slump detection tool has many operation steps and high requirements for personnel operation, which is not convenient to use. Content of the Utility Model

[0037] Embodiment:

[0038] This embodiment provides a concrete slump detector for solving the technical problem that the existing concrete slump detection device is not convenient to use. The concrete slump detector includes a base 1, a slump cone 2, a vibrating member, a magnet 4 and a detecting member, wherein:

[0039] The base 1 is a rectangular plate body with a flat surface and is a structural member made of steel. In this way, detection errors caused by an uneven plate surface are avoided.

[0040] The slump cone 2 has a through hole 21 arranged in the first direction, and the cross-section of the through hole 21 gradually increases in the first direction. It should be noted that the first direction is the axial direction of the slump cone 2. The slump cone 2 is placed on the base 1. The slump cone 2 is used to hold the concrete to be tested. Specifically, the slump cone 2 is frustum-shaped. When in use, the large-diameter end of the slump cone 2 is connected to the base 1, and the small-diameter end of the slump cone 2 extends upward.

[0041] Optionally, a circular positioning mark is provided on the top surface of the base 1. When placing the slump cone 2, the large-diameter end of the slump cone 2 is placed within the positioning mark, which is convenient for the detecting member to detect the height of the concrete.

[0042] The vibrating member is installed on the slump cone 2. The vibrating member is used to vibrate the concrete. In this way, when pouring the concrete into the slump cone 2, the slump cone 2 is vibrated by the vibrating member at the same time, making the concrete in the slump cone 2 more compact and reducing the detection error.

[0043] One end of the magnet 4 is installed on the outer side wall of the slump cone 2, and the other end extends in the second direction. The magnet 4 is adsorbed on the base 1. The first direction and the second direction are perpendicular to each other. The magnet 4 is used to fix the slump cone 2. Through the arrangement of the magnet 4, it is not only convenient to fix the slump cone 2 on the base 1, but also convenient to remove the slump cone 2 from the base 1. Optionally, the number of the magnets 4 is multiple, and the multiple magnets 4 are evenly distributed along the circumferential direction of the slump cone 2. In this way, through the arrangement of the multiple magnets 4, the slump cone 2 can be fixed on the base 1 more stably.

[0044] The detecting member is slidably installed on the base 1 along the first direction. The detecting member is used to detect the height of the concrete. In this way, through the arrangement of the detecting member, it is convenient to detect the height of the concrete before and after slumping, and thus convenient to calculate the slump of the concrete.

[0045] Optionally, a positioning mark is provided on the top surface of the base 1. In this way, it is convenient to align the detecting member with the concrete, that is, it is convenient to make the concrete be in front of the detecting member directly after pouring is completed, avoiding the situation that the detecting member cannot detect the concrete.

[0046] With the above structure, when using the concrete slump detector provided by the present utility model to detect the slump of concrete, first place the slump cone 2 on the base 1 and make the magnet 4 adsorbed on the base 1. In this way, through the setting of the magnet 4, the slump cone 2 is fixed on the base 1 without manual fixation, which is convenient for use. Then pour the mixed concrete into the slump cone 2. While pouring the concrete, turn on the vibrating member to make the vibrating member start vibrating, so that the slump cone 2 connected to the vibrating member also vibrates together, and at the same time the concrete in the slump cone 2 is vibrated. In this way, through the setting of the vibrating member, the concrete in the slump cone 2 is made more dense, so there is no need for manual tamping, which saves time and effort and is more convenient for use. At the same time, due to the setting of the magnet 4, the slump cone 2 is prevented from shifting on the base 1 during vibration. After pouring is completed, the height of the slump cone 2 is detected by the detecting member and recorded, that is, the height when the concrete has not slumped. Then lift the slump cone 2 so that the concrete is completely separated from the slump cone 2. After the concrete ends its natural slump, make the detecting member slide down to detect and record the height of the concrete after slump, and then calculate the slump of the concrete. In this way, through the setting of the detecting member, the height of the concrete before and after slump is automatically recorded, which is more convenient for obtaining whether the slump of the concrete is qualified. Therefore, through the setting of the vibrating member, the magnet 4 and the detecting member, the concrete slump detector provided by the present utility model has simple operation and is more convenient for use.

[0049] The mounting rod 6 has a mounting cavity 61. A chute 62 is opened on one side of the mounting rod 6. The chute 62 is arranged along the first direction and is communicated with the mounting cavity 61. The slider 7 is slidably mounted in the chute 62, and the other end of the slider 7 extends out of the chute 62 and is connected to the detecting member. In this way, through the slidably mounted slider 7, when the slider 7 makes a linear reciprocating motion along the first direction on the mounting rod 6, the detecting member mounted on the slider 7 is driven to move synchronously.

In this way, through the setting of the scales, it is convenient for the staff to detect whether the value on the display screen is correct.

[0055] An alternative implementation of this embodiment is as follows: The vibrating component is a vibrator 3, and the number of vibrators 3 is multiple. The multiple vibrators 3 are evenly distributed on the outer side wall of the slump cone 2. In this way, through the multiple evenly distributed vibrators 3, the concrete is vibrated more uniformly and densely.

[0056] An alternative implementation of this embodiment is as follows: It further includes a controller, which is electrically connected to the laser detector 5, the display 9, the vibrator 3, and the linear module. In this way, through the setting of the controller, it is more convenient to control the laser detector 5, the display 9, the vibrator 3, and the linear module.
