Abstract
The utility model discloses a cement concrete air content testing instrument, comprising a sample container arranged at the bottom and a volumeter barrel. A graded tube is connected with the upper end of the volumeter barrel. The cement concrete air content testing instrument is characterized in that a sealing and connecting device is arranged between the lower end of the volumeter barrel and the sample container to seal and connect the volumeter barrel and the sample container. Rabbling mechanisms which can be lifted and descended are arranged in the volumeter barrel and the sample container, and the rabbling mechanisms are connected with a minitype motor arranged above a closing plug at the port of the graded tube through the closing plug. The cement concrete gas content testing instrument can test the air content of the minute bubbles in the cement concrete, and omits the process of <pressure-air content> calibration. The cement concrete air content testing instrument is simple and convenient to operate in the processes of sampling and loading the sample, saves time and improves testing precision.
Description
Technical field
The utility model relates to a kind of testing tool of cement concrete air content, especially can test the air content instrument of new sand cutting slurry and inside concrete micro-bubble.
Background technology
At present, highway industry (JTGE30-2005) adopts pneumatic process (T0526-2005) air content instrument to test the air content of newly mixing cement concrete according to " highway engineering cement and cement concrete testing regulations ".This instrument is made up of sample container, rain glass, pressue device, water injection pipe and vent valve etc., at first to demarcate " pressure-air content " curve during test, and the air content of gathering materials often carried out calibration (gather materials with compensation in contained air), in actual mechanical process, artifical influence factor is bigger, and pressure application can not reflect the content of micro-bubble in the concrete, easily causes test findings misalignment even failure.
Summary of the invention
Can not reflect micro-bubble content and the big deficiency of interference from human factor in order to overcome existing pneumatic process air content instrument, the utility model provides a kind of volumetric method air content analyzer, this instrument can be measured the air content that new sand cutting slurry and inside concrete comprise micro-bubble, need not the measuring process that " pressure-air content " demarcates, overcome artificial factor.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of tester of cement concrete air content, comprise the sample container of bottom and a capacity bucket at middle part, capacity bucket upper end connects a graduated tube, it is characterized in that, is provided with a sealing and connecting device between described capacity bucket lower end and the sample container both are tightly connected; Be provided with a liftable rabbling mechanism in described capacity bucket and the sample container, this rabbling mechanism connects a micro-machine of sealing-plug top by the sealing-plug of graduated tube port.
In the such scheme, described sealing and connecting device comprises the O-ring seal on capacity bucket and the sample container joint face, the fastener that is symmetricly set on both sides, capacity bucket lower end, profile and spring; Clasp nail is arranged on the fastener, and clasp nail hooks the sample container edge, pulls profile, and under spring action, the capacity bucket promptly is tightly connected with sample container.Described capacity staving is long-pending suitable with the sample container volume.
The beneficial effects of the utility model are, can save the step that " pressure-air content " demarcates in the pressure application in the accurate air content of test measured object, save time, improve measuring accuracy.Adopted sealing and connecting device in the instrument, instrument sample container top is detachable, the operation of convenient sampling dress sample; Adopt the motor stirring apparatus, simple in structure, reduced the interference of manual operation.
Description of drawings
Fig. 1 is an internal structural map of the present utility model.
Fig. 2 is external structure figure of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in Figure 2 as Fig. 1, a kind of tester of cement concrete air content comprises the sample container 18 of bottom and a capacity bucket 11 at middle part, and the capacity staving is long-pending suitable with the sample container volume.Capacity bucket upper end connects a graduated tube 7, and a transparent indicator that has scale is arranged on the scale tube wall; The port of graduated tube is equipped with a sealing-plug 1, and sealing-plug is by the port sealing of sealing gasket 2, screw ring 3 and graduated tube.On sample container and the capacity bucket joint face O-ring seal 17 is arranged, capacity bucket lower end symmetria bilateralis is provided with fastener 15, profile 13 and spring 14; Clasp nail 16 is arranged on the fastener, and clasp nail hooks the sample container edge, pulls profile, and under spring action, the capacity bucket promptly is tightly connected with sample container, and liquid oozes out in the time of can preventing to test; At the discharging when filling with substance, can pull profile in the other direction, under spring action, the capacity bucket promptly separates with sample container, and is therefore easy and simple to handle.Be provided with a liftable puddler 5 in capacity bucket and the sample container, the puddler lower end is provided with paddle 19, puddler connects a micro-machine 20 of sealing-plug top by the sealing-plug of graduated tube port, micro-machine is given stirring vane with transmission of power, to stir the bubble in the sample container sample that looses.Upper/lower terminal is respectively equipped with Upper gasket 4, lower gasket 10 in the graduated tube, and upper and lower pad can limit the position that the joint flange 6 of puddler moves up and down.
The utility model adopts liftable rabbling mechanism, concrete is well-dispersed in sample container in the water that adds by the high scale pipe, based on concrete stir loose after, its inner air is discharged automatically, the volumetric method design concept that liquid level descends, graduated tube shows that the volume that liquid level descends is the contained gas volume of inside concrete, and the volume according to institute's sample container is converted into the gassiness value then.Because of mechanical raking artificial interference factor is little, be easy to fully stir the big material of this glutinousness of concrete that looses, thereby truly reflected its gas inside content, reach the purpose of accurate measurement air content.
