Description

Concrete slump test structure

Technical Field

The utility model relates to a slump test, in particular to slump test structure.

Background

The concrete slump is a standard for judging the workability of concrete construction in actual construction, and the concrete mainly refers to the plasticizing performance and the pumpability of the concrete.

The current slump test method: pouring concrete into a horn-shaped slump bucket with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm for three times, uniformly impacting 25 times along the wall of the bucket from outside to inside by using a tamping hammer after each filling, tamping and leveling.

Then the barrel is pulled up, the concrete generates the slump phenomenon due to the dead weight, and the height of the highest point of the slump concrete is subtracted from the barrel height (300mm), namely the slump

At present, in the charging process, the situation that the added concrete is too much or too little always occurs, too much waste is generated, the site is not neat, and too little experimental data is invalid.

In addition, during the calculation of the difference, the height measurement of the highest point of the collapsed concrete is easy to have errors, so that the calculation of the collapse degree is inaccurate.

The utility model discloses a solve above-mentioned problem, provide a concrete slump test structure, rational in infrastructure, it is simple and convenient to use, has effectively solved the problem that the concrete was loaded, can not cause the waste of concrete, and on-the-spot clean degree is high, simultaneously, the accuracy of experimental data can be guaranteed to this structure, and the test effect is good, and the data is accuracy directly perceived.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a concrete slump test structure, including base and last spacing seat, still including setting up the barrel on the base, the guide pillar through four end angles passes the spacing seat of limiting on that the through-hole that corresponds slides on the spacing seat on the base, still the symmetry is equipped with the locating plate on the base, be equipped with the locating hole on the locating plate, the locating plate passes at least one locating pin side direction of last spacing seat and unilateral and passes the spacing seat and the locating hole realizes the location of last spacing seat, go up the spacing seat between two parties and be equipped with the feed opening, the feed opening acts on the feed inlet department of barrel and both keep level.

Furthermore, the upper limiting seat is provided with a reserved groove for arranging a positioning plate.

Furthermore, a ring plate is arranged around the feed opening.

Further, the guide post (the guide post with scale, the fixed position of the guide post and the base is a scale zero point.

To sum up, the utility model discloses possess following advantage:

the utility model discloses rational in infrastructure, it is simple to use convenient, effectively solved the problem that the concrete was loaded, can not cause the waste of concrete, and on-the-spot clean degree is high, simultaneously, the accuracy of experimental data can be guaranteed to this structure, and the test effect is good, and data is accuracy directly perceived.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic structural view of the upper limiting seat.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

a concrete slump test structure is shown in figures 1 and 2 and comprises a base 1 and an upper limiting seat 2, wherein the base 1 is connected with the upper limiting seat 2, guide posts 11 at four end corners penetrate through corresponding through holes 21 in the upper limiting seat 2 on the base 1 to slide and limit the upper limiting seat 2, and meanwhile, the concrete slump test structure further comprises a barrel 5 arranged on the base.

Still being equipped with locating plate 3 on the base 1 symmetry, specifically being bilateral symmetry setting, can effectually carrying out two-way fixed to last spacing seat, corresponding with it, last spacing seat 2 is equipped with preformed groove 23 and is used for setting up locating plate 3.

With reference to fig. 1, the positioning plate 3 passes through the upper limiting seat 2 and the at least one positioning pin 4 laterally passes through the upper limiting seat 2 and the positioning hole 31 to position the upper limiting seat 2.

And on the setting of feeding of concrete, go up spacing seat 2 and be equipped with feed opening 22 between two parties, feed opening 22 acts on the feed opening department of barrel 5 and both keep level, and is specific, and this feed opening is the circular mouth that is the same with barrel 5 upside feed opening shape, and simultaneously, its week side is equipped with the collar plate 24, can block the concrete.

In order to facilitate the reading of the collapsed concrete and ensure the accuracy of the slump test, the guide post 11 is a guide post with scales, and the fixed position of the guide post and the base is a scale zero point.

Further explaining by combining the use of the device, the barrel is placed on the base, the upper limiting seat penetrates through the guide pillar and the positioning plate 3 and then is positioned at the positioning hole by the positioning pin, and at the moment, the feed opening is aligned with the barrel.

Adding concrete into the barrel body in the feed opening in three times, uniformly beating the barrel body from outside to inside by using a tamping hammer 25 times during adding, then inserting and tamping by using a spatula until the concrete is added into the barrel body and the feed opening is level, if an excessive part appears, scraping the concrete to the edge position, temporarily placing the concrete, and blocking the concrete by using a ring plate.

And then the upper limiting seat is detached, the barrel is taken away to allow the barrel to freely collapse, the upper limiting seat is replaced after the height of the highest point concrete is read after the collapse, the upper limiting seat is moved to the position of the highest point concrete through visual observation, and the scale on the guide post is the height after the collapse.

It should be noted that the whole floor of the base is horizontally located at the same height, so that the reading is accurate and reliable, and of course, the reading of the height is also feasible by using the horizontal cross bar.

After the test is finished, only the concrete on the base needs to be cleaned, and the field cleanliness is high.

To sum up, this scheme is rational in infrastructure, and it is simple to use convenient, effectively solved the problem that the concrete was loaded, can not cause the waste of concrete, and on-the-spot clean degree is high, and simultaneously, the accuracy of experimental data can be guaranteed to this structure, and test effect is good, and the data is accuracy directly perceived.
