Description
Technical field
The utility model is related to a kind of device for detecting gravity flowing levelling mortar mobility, belongs to mortar testing equipment technology neck
Domain.
Background technology
The gravity flowing levelling mortar being made up of Binder Materials, fine aggregate, filler, additive, water etc., can be just flowed using deadweight
Dynamic levelling earth material, if its maximum feature be after uniform mixing without it is artificial it is floating conduct oneself with dignity by slurry cause that surface is put down
It is whole.This mortar speed of application is fast, labour intensity is low, curing time is short, early strength is high, is usually used in large supermarket, market, storehouse
Storehouse, parking lot etc., market potential is very big.
The quality of mortar mobile performance is evaluated in current laboratory and building site using Mortar'S Flowability mostly.According to《JCT
985 ground cement-based self-leveling mortars》Regulation：Internal diameter 30mm, the hollow cylinder of 50mm high are placed on test board center,
After gravity flowing levelling mortar fills the cylinder, start to lift 5cm~10cm in timing, 2s vertically upward, keep 10s~15s to make examination
Sample is freely left, and both direction diameter is surveyed after 4min, and it is Mortar'S Flowability to average.
The method utilizes gravity flowing levelling mortar self gravitation levelling, measures fluidity.But flowed to measurement from die trial is lifted
Degree needs 4min, if two kinds of Mortar'S Flowabilities are 200mm, but flowing time is respectively 1min and 4min, although fluidity
It is identical, but flowing time has obvious difference, therefore, the method detection is inaccurate.
Utility model content
The utility model aims to solve the problem that in the prior art the accuracy of gravity flowing levelling mortar mobility-detected device is not high enough
A kind of technical problem, there is provided device of new detection gravity flowing levelling mortar mobility, by store slurry box, connection box and measuring box and
Scale on measuring box is set, and can more accurate, easily carry out the detection of gravity flowing levelling mortar mobility.
In order to realize foregoing invention purpose, the technical solution of the utility model is as follows：
A kind of device for determining gravity flowing levelling mortar mobility, it is characterised in that：Including storage slurry box, connection box and measuring box；
The storage slurry box top is provided with pulp inlet, is connected between the connection box and storage slurry box, is set between the connection box and measuring box
There is draw-in groove, baffle plate movable up and down is provided with the draw-in groove；The measuring box is provided with two graduation mark h1、h2, from cassette bottom
Highly it is respectively H1And H2。
The step of detecting mortar mobility using the utility model is as follows：
1）During baffle plate snapped in into draw-in groove first, and mortar is imported in storage slurry box from pulp inlet, slurry slowly fills storage slurry
Box with connect box, until mortar with storage slurry box pulp inlet flush, then with doctor blade surface；
2）Quick to lift baffle plate, mortar flows to measuring box under the effect of the pressure, when slurry face reaches scale h1When, start
Timing, slurry face reaches h2Stop timing during height, obtain time difference △ t.
△ t can reflect the deformation velocity of slurry, and the gravity flowing levelling mortar of identical fluidity, △ t are smaller, represent thixotropy
It is better, show that mortar plasticity is better, be conducive to site construction.
In order to the utility model is better achieved, further, the measuring box top is provided with grout outlet.
The height H of the storage slurry boxZWith the height H of measuring boxCRatio Hz/HCIt is 2~3.
The length L of the storage slurry boxZ, width WZWith the length L of measuring boxC, width WCIt is identical, and length is more than width.Institute
State the height H of connection boxLWith H1Ratio：HL/ H1It is 1/3~2/3；Connect the width W of boxLWith LZ、LCIt is identical, length LLIt is more than
WL, HL/ H1Ratio is to ensure particle loaded fluid surface current to h for 1/3~2/31It is level during graduation mark, reduces time measurement and miss
Difference.
H on the measuring box1Scale H1With measuring box height HCHeight ratio is 1/4, h2Scale H2With measuring box height HC
The ratio of height is 3/4.
The beneficial effects of the utility model：
（1）Compared with mortar mobility-detected device of the prior art, the utility model using storage slurry box, connection box,
The setting of measuring box and baffle plate, allows mortar first to fill storage slurry box and connect box, after stabilization, then lifts baffle plate, carries out epidemic
Measurement, advantage simple with apparatus structure, easy to operate.
（2）Measuring box top of the present utility model is provided with grout outlet, with after the completion of facilitating mortar fluidity testing, to device
Cleaning, cleaning way is to add clear water, the waste water of cleaning to be flowed out from grout outlet from pulp inlet.
（3）In the utility model, the height H of storage slurry boxzWith the height H of measuring boxCRatio Hz/HCIt is 2~3, according to connection
Device principle, one end high from liquid level that gravity flowing levelling mortar can be spontaneous is flowed to low one end, and final two ends slurry face is equal.When storage is starched
Box height is when being just the twice of measuring box height, experiment terminate after each half of both sides mortar in theory, but mortar can be in storage
Slurry box wall on remained, in measuring box slurry less than.In order to avoid mortar stream is less than graduation mark h2Cause the failure of an experiment, storage slurry
The height H of boxZWith the height H of measuring boxCRatio should be greater than 2；If further, the height H of storage slurry boxZIt is too high, gravity flowing levelling mortar meeting
Under levels pressure effect, flow velocity is too fast, causes time measurement error big, and experimental data is unreliable.Therefore, this size design subtracts
Lack experimental error, increase data reliability.At the trial, the storage slurry of different height can be selected according to gravity flowing levelling mortar fluidity
Box and measuring box.
（4）In the utility model, the length L of storage slurry boxZ, width WZWith the length L of measuring boxC, width WCIt is identical and long
Degree be more than width, such size design also for reduce time measurement error, according to hydrodynamics, gravity flowing levelling mortar fluidised form
It is bingham model, storage slurry box is consistent with measuring box length and width size to effectively reduce the turbulent flow produced in flow process, it is ensured that mortar
Liquid level is in h1And h2It is level during graduation mark, so as to improve certainty of measurement.
（5）In the utility model, h on measuring box1The H of scale1With measuring box height HCRatio is 1/4, h2The H of scale2With
Measuring box height HCIt is highly 3/4, long term test is proved, graduation mark h is marked at measuring box entrance and exit 1/41And h2, it is
Because mortar flowing is small by ectocine between two graduation marks, time measurement is relatively accurate.
（6）The utility model, according to law of connected vessels and hydrodynamics, using suitable size design, reduction was tested
Error in journey, it is ensured that the accuracy of time measurement, it is achieved thereby that more accurately trying gravity flowing levelling mortar mobility
Test.
