Abstract
A fixture for measuring electric parameters of concrete is used for fixing a concrete sample to be electrified. An upper electrode (5) and a lower electrode (2) are arranged on the middle shaft of thefixture, wherein the upper electrode (5) can move up and down; the lower electrode (2) is fixed on a base (1); and pillars (10) are formed on both sides of the fixture. When an upper handle (3) is lifted, the concrete sample can be placed between the two electrodes which are connected with an external power supply.
Description
Affiliated field
The utility model belongs to the instrument of measuring concrete quality, the anchor clamps that use when being specifically related to detect.
Background technology
Concrete perviousness is to judge the key factor of concrete quality, the standard of measuring concrete charge pass has been fixed by the U.S. as far back as the eighties, this standard need be switched on 6 hours, and the concrete perviousness of the high more explanation of the electric weight that passes through is strong more, and concrete permanance is poor more.But this method of testing, length consuming time, operation inconvenience, measurement result is not accurate enough.
Goal of the invention
For the more convenient operation of energy, use the shorter time to obtain measurement data more accurately, the inventor has invented a kind of measurement by the concrete sample electricity is led according to the NEL method, converses concrete infiltrative surveying instrument.In this surveying instrument, the anchor clamps that are used for fixing sample are very important for measurement result.Therefore the utility model proposes a kind of anchor clamps that the concrete sample electricity is led that are used to measure.
The technical scheme that realizes the utility model purpose is such: at base 1 and entablature 4 by pillar 10 support and connection, the bottom electrode 2 of the upper/lower electrode in a pair of same axle center is fixed on base 1 upside, top electrode 5 is fixed on conducting rod moving up and down 7 lower ends at entablature 4 centers, and conducting rod 7 upper ends are handle 3.
Use measured material of the present utility model, cooperate current measurement instrument again, only needed 10 minutes just can accurately test out concrete perviousness, thereby can make the judgement of concrete durability quality faster.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is another structural representation of the utility model.
Embodiment
In conjunction with the accompanying drawings the utility model is described.
When the measurement that the concrete sample electricity is led,
In the jig frame of base 1 and entablature 4 and pillar 10 support and connection, the handle 3 at entablature 4 centers is mentioned, selecting suitable concrete sample to be placed on the bottom electrode 2 of base 1 upside, handle 3 is put down, because the acting in conjunction of the conducting rod 7 of handle 3 and its underpart and top electrode 5 weight of conducting rod 7 lower ends makes electrode 5 tightly press on concrete sample.Two electrodes are received on the surveying instrument, just can have been obtained measurement result very soon.In order to guarantee the accuracy of measurement result, upper/ lower electrode 2,5 must be on same axle center, and electrode area is identical.
To move up and down smooth and easy between conducting rod 7 and the entablature 4 and guarantee that upper/ lower electrode 5,2 is concentric in order to make, between entablature 4 and conducting rod 7 locating sleeve 6 is arranged, what the bayonet lock 13 on conducting rod 7 and top thereof can not rock in locating sleeve 6 moves up and down.
Load and unload concrete sample for convenience, bayonet lock 13 is housed, when handle 3 is mentioned on conducting rod 7 tops, after bayonet lock 13 on the conducting rod 7 exposed locating sleeve 6, rotary handle put down again, and bayonet lock is stuck on the locating sleeve 6, concrete sample just can be loaded and unloaded easily in top electrode 5 location.Rotate back to handle after waiting to load and unload again, the groove of bayonet lock on locating sleeve falls, and electrode just has been returned to original position.
For convenience the upper/ lower electrode 5,2 of anchor clamps is connected with surveying instrument, and pillar 10 is provided with binding post 11,12 and is connected by conductive material with upper/ lower electrode 5,2 respectively.
For top electrode 5 also can closely be contacted with the upper surface of concrete sample when concrete sample is nonstandard, spheroidal is made in the bottom of conducting rod 7,5 one-tenth spheres of itself and top electrode can be rolled be connected.When the upper surface of concrete sample is gradient, still can closely contact with electrode.
Also can be connected between conducting rod 7 lower ends and the top electrode 5 with the spring of conduction.
