Abstract

The utility model discloses a slump meter for highway concrete detection, which comprises a base and a slump cylinder placed on the upper part, handles are fixed on both sides of the slump cylinder, and a funnel is arranged above the slump cylinder. A horizontal support rod is fixed on the outer side of the top edge of the slump cylinder, a vertical sliding rod is fixed at the lower part of the outer end of the support rod, a sliding sleeve is slidably connected to the sliding rod, and the side of the sliding sleeve is connected to the arc through the connecting rod. The curved ferrule is fixed, and a laser pointer is clamped on the curved ferrule. The utility model can quickly measure the slump value of the concrete slurry by arranging an adjustable laser pointer on the side of the slump cylinder. The process does not need to erect a measuring ruler to save time and improve efficiency, and the accuracy of slump measured by laser pointer scanning is greatly improved, ensuring the accuracy and qualification of the experiment.

Description

Slump tester for highway concrete detection

Technical Field

The utility model relates to a concrete detection field, concretely relates to highway concrete detects uses slump tester.

Background

Most highway subgrades are formed by pouring concrete, and quality detection of the concrete before use is indispensable for ensuring the pouring quality of the subgrades. Slump tests are a very important item in concrete quality testing. The slump test can determine the fluidity characteristic of the concrete slurry, and the larger the slump, the better the fluidity of the filled concrete slurry is, and the smaller the yield stress of the filled concrete slurry is. Current slump testing arrangement generally includes a slump section of thick bamboo and funnel, through the funnel to the inside concrete slurry that adds of a slump section of thick bamboo, again with the slump section of thick bamboo take up fast, concrete slurry can flow to both sides, use the measuring tape to measure the interval between concrete slurry highest position and the slump section of thick bamboo top after the flow is accomplished, this has just accomplished measurement work, but artifical need observe concrete slurry highest position and measure when using the measuring tape to measure, the time of setting up the measuring tape has both been wasted in this kind of measurement, be difficult to guarantee again that measuring precision is unqualified from leading to the test, influence the road bed quality of pouring.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of the existence, the utility model provides a highway concrete detects uses slump tester.

The utility model discloses a realize through following technical scheme:

the utility model provides a highway concrete detects uses slump appearance, includes the slump section of thick bamboo that base and upper portion placed, the both sides of a slump section of thick bamboo are fixed with the handle, and slump section of thick bamboo top is provided with the funnel, slump section of thick bamboo top edge outside is fixed with the horizontally bracing piece, bracing piece outer end lower part is fixed with the vertically slide bar, sliding connection has the sliding sleeve on the slide bar, the sliding sleeve lateral part passes through the connecting rod and is fixed with the arc cutting ferrule, the joint has the laser pen on the arc cutting ferrule.

Preferably, the laser pen is perpendicular to the sliding rod.

Preferably, the slide bar is marked with scale marks for measuring the length.

Preferably, the support rod is horizontally arranged with the top of the outer wall of the slump cone.

Compared with the prior art, the beneficial effects of the utility model are that: this practicality can measure the slump numerical value of concrete slurry fast through the laser pen that can adjust in slump section of thick bamboo lateral part setting, and whole measurement process need not erect the measuring tape and saves time raise the efficiency, and the slump accuracy through laser pen scanning measurement improves by a wide margin, guarantees that the accuracy of experiment is qualified.

FIG. 2 is a schematic enlarged view of a portion of the structure of FIG. 1;

FIG. 3 is a schematic view of the present application in use;

in the figure: base 1, slump section of thick bamboo 2, handle 3, funnel 4, bracing piece 5, slide bar 6, scale mark 7, sliding sleeve 8, connecting rod 9, arc cutting ferrule 10, laser pen 11, concrete thick liquids 12.

Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings:

as shown in fig. 1, fig. 2, fig. 3, a slump appearance is used in highway concrete test, including base 1 and the slump section of thick bamboo 2 that upper portion was placed, the both sides of a slump section of thick bamboo 2 are fixed with handle 3, and slump section of thick bamboo 2 top is provided with

funnel

4, 2 top edge outsides of slump section of thick bamboo are fixed with horizontally bracing piece 5, 5 outer end lower parts of bracing piece are fixed with vertically slide bar 6, sliding connection has sliding sleeve 8 on the

slide bar

6, 8 lateral parts of sliding sleeve pass through connecting rod 9 and arc cutting ferrule 10 are fixed, the joint has laser pen 11 on the arc cutting ferrule 10.

The laser pen 11 is perpendicular to the sliding rod 6.

The slide bar 6 is marked with scale marks 7 which are the same as the scale marks for measuring the length.

The support rod 5 is horizontally arranged with the top of the outer wall of the slump cone 2.

The working principle is as follows: when the utility model is used, the base 1 is horizontally placed, the slump cone 2 is placed in the center of the base 1, concrete slurry is poured into the slump cone 2 through the funnel 4 and is filled, after the slump cone is filled, the handle 3 is held by two hands to drive the slump cone 2 to move upwards and quickly to separate from the concrete slurry, the concrete can move to two sides, the slump cone 2 is placed on the base 1 at one side of the concrete slurry after the movement is stopped, the slide bar 6 is just opposite to the concrete slurry, the laser pen 11 is opened, the height adjustment of the laser pen 11 is realized by moving the slide bar 6 through the slide sleeve 8, meanwhile, the strong laser emitted by the laser pen 11 on the rotary slide sleeve 8 can be swept back and forth, thus the whole adjusting strong laser can hit the highest position of the concrete slurry 12, after the highest position is reached, the scale line 7 corresponding to the top of the slide sleeve 8 is read, the slump can be calculated by recording data, therefore, the whole process of measurement is not needed to be provided with a measuring scale, the time is saved, the efficiency is improved, the slump precision of the scanning measurement through the laser pen 11 is greatly improved, and the accuracy and the qualification of the experiment are ensured.
