Abstract
Even matter nature of concrete and continuity test device that flows, it includes concrete container (1), a -frame (2), a set of outlet pipe (3), a set of outlet pipe end -blocking (4), rinses a mouthful end -blocking (6), one a pool -size section of thick bamboo (7) and a set of plat form scale (8), the utility model discloses the advantage is: the device both easy operation, save time, again simply the intuitive judgment concrete even matter nature with the continuity flows to the even matter nature and flow continuity of concrete can quantitatively be signified through simple calculation.
Description
Technical field
The utility model relates to concrete test apparatus field, is specifically related to homogeneity of concrete and flowing continuity test device.
Background technology
Concrete Pumping Construction is a kind of construction method of current civil construction field widespread use, and in building operation, concrete pumping is built and improve operating efficiency, ensure that the continuity of construction casting, has significant contribution to building operation.
Whether the quality of concrete pumping performance depends on homogeneity and the flowing continuity of concrete mix to a great extent, and homogeneity reflects concrete and whether has enough education resistance energy, can sink to causing pumping to be deteriorated because of aggregate; Flowing continuity reflects the height of concrete pumping efficiency, and not only pump-conveying property is good for flowing continuous print concrete, and meanwhile, pumping efficiency is higher, during unlikely because concrete pumping desultory " extruding " and reduce pumping efficiency or occur the accidents such as plugging.
At present two kinds of methods are mainly contained to the test of homogeneity of concrete, first method puts into concrete in the system of the hydrostatic column composition being divided into three joints, then entirety is put and is vibrated on a vibration table, subsequently, three joint concrete are transferred in three capacity tubes respectively, clear water rinses concrete, and leave coarse aggregate and weigh, the weight differential comparing three points of coarse aggregates judges homogeneity; A kind of method measuring concrete mix homogeneity and glutinous poly-property is disclosed in Chinese invention patent 201010256456.6, concrete hopper is uniform motion in orbit, quantity and the concrete quality of hopper that concrete in motion process falls into hopper got by meter, judges concrete homogeneity and glutinous poly-property by calculating.
Two kinds of method of testings respectively have deficiency: the first method running time is long, test complicated, and the concrete in three pitch circle cylindrical containers of equal for two ends opening is being transferred in capacity tube process, be difficult to avoid concrete trickling down, therefore the method operation is complicated, time-consuming length, test accuracy is also worth discussion; Second method is when testing, do not consider that the concrete in hopper reduces gradually in uniform motion process, the speed falling into hopper is reduced gradually and the factor that makes hopper below fall into concrete quantity to reduce, namely have ignored concrete in hopper to the effect of concrete pressure being about to fall into hopper.Two kinds of methods all fail to embody concrete this index of flowing continuity.
Utility model content
The purpose of this utility model is exactly for deficiency above-mentioned at present, and provides homogeneity of concrete and flowing continuity test device.
The utility model comprises concrete container, A-frame, one group of effuser, one group of effuser end-blocking, Butterworth Hatch end-blocking, one pool-size cylinder and one is organized a performance scale, concrete container is arranged on A-frame top, concrete container side has one group of hole by bottom position, one group of effuser is arranged in hole respectively, one group of effuser end-blocking is arranged on the discharging opening of one group of effuser respectively, Butterworth Hatch is had bottom concrete container, Butterworth Hatch end-blocking is arranged on Butterworth Hatch, one pool-size cylinder is placed on one respectively and organizes a performance on scale, and a pool-size cylinder lays respectively at below the discharging opening of one group of effuser.
Described concrete container is rustless steel container, and concrete container is rounding frustum.
The diameter of described effuser is 10 ~ 15 centimetres.
The diameter of described Butterworth Hatch is 10 ~ 15 centimetres.
The range of described platform balance is not less than 10kg, and precision is 0.01 ~ 0.1kg.
The utility model advantage is: this device both simple to operate, save time, again can simple, intuitive judge concrete homogeneity with flowing continuity, and by simple computation can the concrete homogeneity of quantitatively characterizing with flowing continuity.

Fig. 1 is the structural representation of the utility model front view.
Fig. 2 is the structural representation of the utility model vertical view.
Embodiment
As Fig. 1, shown in 2, the utility model comprises concrete container 1, A-frame 2, one group of effuser 3, one group of effuser end-blocking 4, Butterworth Hatch end-blocking 6, one pool-size cylinder 7 and one is organized a performance scale 8, concrete container 1 is arranged on A-frame 2 top, concrete container 1 side has one group of hole by bottom position, one group of effuser 3 is arranged in hole respectively, one group of effuser end-blocking 4 is arranged on the discharging opening of one group of effuser 3 respectively, Butterworth Hatch 5 is had bottom concrete container 1, Butterworth Hatch end-blocking 6 is arranged on Butterworth Hatch 5, one pool-size cylinder 7 is placed on one respectively and organizes a performance on scale 8, and a pool-size cylinder 7 lays respectively at below the discharging opening of one group of effuser 3.
Described concrete container 1 is rustless steel container, and concrete container 1 is rounding frustum.
The diameter of described effuser 3 is 10 ~ 15 centimetres.
The diameter of described Butterworth Hatch 5 is 10 ~ 15 centimetres.
Described capacity tube 7 is iron casting.
The range of described platform balance 8 is not less than 10kg, and precision is 0.01 ~ 0.1kg.
Working method: during use, effuser end-blocking 4 seals the discharging opening of effuser 3, Butterworth Hatch end-blocking 6 seals Butterworth Hatch 5, capacity tube 7 is placed on the position corresponding with effuser 3 discharging opening, the concrete that access is flowed out, concrete is loaded in concrete container 1, leave standstill in a moment, open effuser end-blocking 4, observe and the number of times of the concrete recording effuser 3 intermittently " extruding ", number of times more multilist bright concrete continuous mobility is poorer; After concrete stream sky in concrete container 1, the platform balance 8 be placed on below capacity tube 7 takes quality automatically, and deducts capacity tube deadweight, and the concrete quality in capacity tube 7 is more better close to homogeneity of concrete.Finally, open Butterworth Hatch end-blocking 6, irrigation tests equipment, waits until follow-up test.
Can the concrete homogeneity of rational judgment and flowing continuity by simple computation.
Computing formula is:
Y
i=W
i-W
0
X=∑d
i
In formula: Y
i---homogeneity of concrete; Y
imore better close to homogeneity
W
i---i-th capacity tube and concrete general assembly (TW);
W
0---the deadweight of capacity tube;
X---concrete flowing continuity; X larger flowing continuity is poorer
D
i---the number of times of the concrete intermittent " extruding " of i-th effuser.
