Description
Technical field
The utility model belongs to construction material testing equipment field, and in particular to a kind of modulus of rupture and destruction of Ceramic Tiles
The detection device of intensity.
Background technique
According to the regulation of national standard GB/T3810.4-2016, measurement structure such as Fig. 1 institute of the modulus of rupture and breakdown strength
Show.
The requirement of detection device is as follows:
1. support stick is consistent with center bar diameter, Ceramic Tiles are divided three size sections, each size model by size by standard
A kind of corresponding support stick and center bar are enclosed, then for the three classes size range of brick it is necessary to which there are three types of the sticks of size.
2. distance is adjustable between liang support stick, distance is test brick length plus " brick stretches out the length outside support stick
Degree ".
3. standard requirements preferably apply full sized brick to test, while defining the upper limit: it must be length≤600mm rectangle, it is right
In the brick and non-rectangle brick that are greater than 600mm, it need to be scaled to be cut.
Circular central stick diameter is identical as two support sticks, and has rubber layer package, this stick can also slightly be swung, for passing
Pass load.When detection, ceramic tile detects style lower part and two support sticks is arranged, and top is pushed by center bar applies pressure F, in porcelain
When brick is broken, breaking load mechanics value is recorded, then calculates other performance indicators such as the modulus of rupture.Wherein center bar and two circles
Core is made with metal in pillar support stick, with sample contacts part with hardness be 50IRHD ± 5IRHD rubber package, rubber
Hardness is measured by ISO48, and a support stick can slightly be swung, and another support stick can slightly be rotated around its axis.
Branch is stretched out to the diameter d of the size L of ceramic tile sample, barred body, the thickness T of rubber layer and ceramic tile style both ends when detection
Support the length l outside stick1, there is size regulation, be detailed in following table (unit is millimeter):
The breakdown strength test fixture of Ceramic Tiles in the prior art, can neither be rolled using three, can not be swung
Fixed metal mandrel, is supported pressurization to ceramic tile, does not meet the installation requirement of national standard aligning arbor and support stick, and can not be steady
It is fixed to place and test ceramic tile sample.Further, since providing that two support barred bodies must have one to have and spin around axis in national standard
Turn characteristic, and another has swingable characteristic, therefore placement of the ceramic tile before compression is not at equilibrium state, if in
Axle force down stroke it is too long, ceramic tile test specimen may run-off the straight even slide.
On the pressure arm that center bar passes through bolt cut-in pressure machine, lower support stick presses same mounting means cut-in pressure
Machine.By adjusting the gliding speed that moves up of pressure arm, the Ceramic Tiles of support stick support under control pressure arm drives center bar to contact
Sample.Since the rate control to universal testing machine relies on the range estimation of laboratory technician completely, then in specific test, when range estimation is seen
When observing center bar and ceramic tile sample contacts, it is easy to appear the stopping movement of manual operation testing machine and is moved down with testing machine pressure arm
Between time difference so that ceramic tile sample i.e. stress before not starting breakdown strength test, the destruction as needed for Ceramic Tiles
Pressure only has several newton, then tests and does not carry out, and sample destroyed leads to test failure.
Furthermore according to national standard, for the ceramic tile sample of different length, need to adjust each barred body diameter and
Away from and rubber layer thickness, with control ceramic tile sample both ends stretch out support stick outside length l1Meet national standard.It is existing to set
It is standby to implement conveniently and accurately above-mentioned adjusting operation completely, cause the collected data of test process there are severe deviations,
It cannot really reflect ceramic tile breakdown strength performance required by national standard.
In consideration of it, applicant devises the present apparatus according to practical operation situation, in conjunction with the requirement of national standard, it can be conveniently and smart
True implements breakdown strength detection to ceramic tile sample.
