Description
Technical field
The utility model relates to a kind of concrete quality pick-up unit, particularly a kind of normal concrete mixture slump device for fast detecting.
Background technology
The construction work normal concrete was called the normal concrete mixture before setting and harden not.It must have good denseness (workability) and be convenient to constructing operation (mix, transportation, pouring, tamping) and can obtain the performance that quality is even, moulding is closely knit.Simultaneously, also be for after guaranteeing normal concrete mixture setting and harden, should have enough intensity, with the permanance that guarantees that buildings can bear design load safely and should have.
Denseness (workability) is comprehensive technological property of normal concrete mixture, and it comprises the implication of three aspects such as flowability, glutinous poly-property and water-retaining property.
Flowability is meant the normal concrete mixture under the effect that dead weight or construction machinery vibrate, and can produce and flow, and evenly fill up the performance of template densely.
Glutinous poly-property is meant that the normal concrete mixture has certain glutinous poly-property, the phenomenon of unlikely generation layering and segregation between its composition material in work progress.
Water-retaining property is meant that the normal concrete mixture in work progress, has certain water holding capacity, the excreting water phenomenon that unlikely generation is serious.And the concrete mix of generation excreting water phenomenon because moisture secretes out meeting formation permeable hole easily, and influences concrete density, the reduction quality.
Regulation according to existing national standard " Standard for test methods of properties of ordinary concrete mixture standard ", the check maximum aggregate size be not more than 40 mm, when the slump is not less than normal concrete mixture denseness (workability) index of 10 mm, test method adopts the slump consistancy test method, and all is this general test method that adopts with having now in the past always.
The employed equipment of existing slump consistancy test and other apparatus are:
1, the regulation that requires according to " concrete slump instrument " JG3021 relevant technologies is tested used equipment (slump cone) with sheet steel or other metal truncated cone-shaped tube.In Fig. 1, its inner wall smooth of slump cone, no concave-convex position.Bottom and end face answer parallel to each other and with the axis normal of cone.2/3rds highly locate two handgrips of peace, bottom welding foot pedal outside the tube that collapses.The inside dimension pattern of tube is: base diameter 200 ± 2mm; Top diameter 100 ± 2mm; Height 300 ± 2mm; Barrel thickness is not less than 1.5mm.
2, other apparatus.Tamper, tamper pattern are the rod iron of diameter 16mm, long 650 mm, and rounding is answered in the end.Surface level with solid (not absorbing water) is done base plate.
Present stage the slump consistancy test step
1, moistening slump cone and base plate do not have open fire on slump cone inwall and base plate.Base plate should be placed on the surface level of solid (not absorbing water), and tube is placed on the base plate center, the pedal on two limits that tramp with one's feet then, and slump cone is in position that when filling with substance should be maintained fixed.
2, the concrete sample of obtaining is on request divided in the three layers of tube of packing into equably with scuppit, make every layer height after the tamping for tube high about 1/3rd.Insert with tamper for every layer and smash 25 times.
3, behind the concrete on the base plate of removing tube limit, mention to vertical equilibrium slump cone.The process of lifting from of slump cone should be finished in 5-10s; Should carry out incessantly from beginning to be charged to the whole process of carrying slump cone, and should in 150s, finish.
4, mention slump cone after, measure that tube is high to try difference in height between the body peak with the back concrete that collapses, be the slump value of this concrete mix, shown in the A among Fig. 1.
5, observe the glutinous poly-property and the water-retaining property of the concrete examination body after collapsing.
There are the problem and shortage of following four aspects in the employed equipment of existing slump consistancy test and other apparatus.
1, the plane requirement of base plate placement is surface level and solid (not absorbing water), the regulation of its levelness and solid (not absorbing water) lacks determinacy and uniqueness, the working-yard under various construction environment and condition particularly, the plane that its base plate of the place that in situ test is selected is placed require to be levelness and solid (not absorbing water) otherness and random big.Shop experiment is tested both spent operating manpowers, time, test error etc. with the working-yard and is compared, and otherness can be bigger.
2, slump cone is placed on the base plate center, the pedal on two limits that can only tramp with one's feet makes slump cone in position that when filling with substance is maintained fixed.Need two personnel operation simultaneously, the pedal that people's pin is stepped on two limits is slump cone fixedly, and people charging is compacted concrete also, and work efficiency is slow, and fixedly the slump cone labour intensity of standing for a long time is big; Insert at tamper and to smash in the process, produce certain friction resistance between slump barrel and the concrete mix, slump cone makes progress or move left and right easily, concrete examination height degree increase thereupon or the deflection chassis center outside, concrete examination height degree tends to surpass the calibrated altitude of slump cone 300mm, influences the measurement authenticity and the accuracy of its standard concrete cone difference in height.
3, mention slump cone after, measure tube high with the slump after during difference in height A between the concrete examination body peak, graduated scale levelness or graduated scale verticality all adopt ocular estimate, and be greatly random.The difference reading of scale and concrete cone height is not directly perceived, and reading error is also bigger, and the requirement that slump height difference measuring is accurate to 1 mm is difficult to reach.
4, the operating space is little, environment is poor.Adopt people's pin to step on the pedal on two limits and be close to fixedly slump cone, slump cone is in charging and tamper is slotting when smashing concrete mix, personnel operation activity space relative fixed, simultaneously, when smashing concrete mix in charging with tamper is slotting, big to people's clothing pollution, operation is extremely inconvenient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of normal concrete mixture slump device for fast detecting, can measure the normal concrete mixture slump quickly and accurately, and easy to operate.
