Abstract
The utility model discloses an anti segregation performance detection device of concreting of big drop free fall comprises slump bucket, circular net, bracing piece and material receiving container. Wherein, the slump barrel is connected with the support bar in an inverted manner, the height of the lower end of the barrel from the bottom surface of the material receiving container can be adjusted by moving up and down along the support bar, the lower end of the barrel is provided with a sealing cover, the circular net is fixed on the support bar, and the support bar is fixed on the material receiving container. During detection, concrete mixture is scattered into the material receiving container sequentially through the slump bucket and the circular net, and whether the concrete mixture in the container has the phenomena of separation of slurry and bone and bleeding or not is observed, so that the segregation resistance of the large-fall free-falling pouring concrete is judged.
Description
Technical Field
The utility model belongs to the technical field of building material, concretely relates to anti segregation performance detection device of concreting of large drop free fall.
Background
Concrete is one of the leading civil engineering materials of the present generation and is generally prepared from cement, admixtures, sand, stone, water and additives in a certain proportion. In the process of pouring concrete, in order to prevent segregation, the existing specification GB 50164 one-pass 2011 stipulates that the free-fall height of the concrete is not more than 3.0m, and in the actual construction process, large-fall free-fall pouring often exists, which undoubtedly puts higher requirements on the segregation resistance of the concrete. However, under the specific construction conditions of large-fall free-fall pouring, how to judge the segregation resistance of the concrete mixture does not have a standard detection device and detection method at present, so that a detection device for the segregation resistance of the large-fall free-fall pouring concrete is needed to be developed.
Disclosure of Invention
To the shortcoming or the deficiency of above-mentioned prior art, the utility model aims to provide a big drop free fall concreting anti segregation performance detection device.
For realizing the task, the utility model provides a technical scheme does:
the utility model provides a big drop free fall concreting anti segregation performance detection device comprises slump bucket, circular net, bracing piece and material receiving container, wherein: the lower part of the support rod is fixed on one side of the material receiving container, the slump bucket is inverted, one side of the slump bucket is connected with the support rod, and the slump bucket can move up and down along the support rod and is used for adjusting the height from the lower end of the slump bucket to the bottom surface of the material receiving container; slump bucket lower extreme is provided with sealed lid, and on circular net was fixed in the bracing piece, slump bucket, circular net and connect material container's center were on same vertical line.
The utility model discloses in, the diameter of circular net is unanimous with the less port diameter of slump bucket.
The utility model discloses in, connect the material container length to be 800~1000mm, the width is 800~1000mm, and the height is 100~200 mm.
The beneficial effects of the utility model reside in that: the utility model provides a big drop free fall concreting anti segregation performance detection device that freely inclines, pour to the construction of big drop free fall, the phenomenon that concrete mixture segregates easily detects effectively to ensure the pouring quality of concrete.
Drawings
Fig. 1 is the utility model discloses a big drop free fall concreting anti segregation performance detection device schematic diagram.
Reference numbers in the figures: 1. the device comprises a support rod, 2, a slump bucket, 3, a sealing cover, 4, a circular net, 5 and a material receiving container.
Detailed Description
In order to make the contents, technical solutions and advantages of the present invention more apparent, the present invention will be further described with reference to specific embodiments.
Example 1:
as shown in figure 1, the device for detecting the segregation resistance of the cast concrete with the large drop height and free fall comprises a slump bucket 2, a circular net 4, a support rod 1 and a material receiving container 5, wherein the slump bucket 2 is inverted and connected with the support rod 1, the height of the lower end of the slump bucket from the bottom surface of the material receiving container 5 can be adjusted by moving the lower end of the slump bucket up and down along the support rod 1, a sealing cover 3 is arranged at the lower end of the slump bucket, the circular net 4 is fixed on the support rod 1, and the support rod 1 is fixed on the material receiving container 5.
The utility model discloses in, slump bucket 2, circular net 4 and connect the center of material container 5 on same vertical line. The diameter of the circular net 4 is consistent with the diameter of the smaller port of the slump barrel 2 and is 50cm away from the bottom surface of the material receiving container 5. The receiving container 5 is 1000mm long, 1000mm wide and 200mm high.
The utility model discloses a detection method as follows:
(1) adjusting the distance between the lower end of the slump cone 2 and the bottom surface of the material receiving container 5 according to the free falling pouring height of concrete mixture during construction, namely the free falling height of the sample, and setting the free falling heights of the sample to be 0.8m, 1.2m and 1.6m when the free falling heights of the concrete during construction are respectively 3-5 m, 5-8 m and more than 8 m;
(2) sampling or preparing a sample according to a method in general concrete mixture performance test method standard GBT 50080-2016, and filling the slump bucket 2 with the concrete mixture;
(3) opening the sealing cover 3 to enable concrete mixture to be scattered into the material receiving container 5 through the circular net 4;
(4) and observing whether the concrete mixture in the material receiving container 5 has phenomena of separation of slurry and bone, bleeding and the like, thereby judging the anti-segregation performance of the concrete mixture which freely falls off under large fall.
Claims (3)
