Description
Technical field
The present invention relates to the sample preparation device of a kind of material of construction detection, the sample preparation mold of standard brick strength trial of specifically building a wall.
Background technology
Brick of building a wall is a kind of material of construction that building field widely uses, and its quality quality directly affects the quality of building. An important technology parameter of brick quality quality of building a wall is ultimate compression strength, in order to accurately test out the ultimate compression strength of brick of building a wall, it is important to need to prepare the test sample meeting national standard.
The traditional method manufacturing brick test sample of building a wall is the mode adopting cement paste manually to wipe one's face, that is, on the worktable of level, pad upper berth slurry paper, will stir uniform cement paste material-paving in right amount and starch on paper in this paving, touch evenly with perching knife paving thereupon. Again by test by the plane of brick sample of building a wall just to slurry face and compacting, measure with level bar and ensure its planeness. Then with middle layer and the another side of the levelling sample of same method, and maintenance (be placed in by levelling sample the environment not ventilated being not less than 7 DEG C under maintenance 3 days) is carried out. Just compressive strength test is carried out by testing apparatus after maintenance is good.
The sample handling processes that above-mentioned tradition cement paste is manually wiped one's face, the impact by human factor is relatively big, such as, sample load face cement paste layer homogeneity is not good; The thickness of cement paste layer is difficult to control, even also there will be the big block bubble parting in local after maintenance. Even if between same sample, adopt the mode that this kind of cement paste material is manually wiped one's face, also may there is larger difference, these differences will directly have influence on the assay of the final ultimate compression strength of product, especially for the sample being in intensity critical state, it more difficult to judge whether this assay reflects the mechanical property of product truly. The shortcomings such as in addition, it is excessively long that traditional method also exists preserving period, and test efficiency is low, the repdocutbility difference of test.

Mould is placed on standard operation platform, the base plate securing bolt of mould both sides is first unclamped with allen wrench, unclamp the spacing controllable register (right side plate 5-1, left plate 5-2) of both sides before and after mould again, while a hand pushes down mould, another hand extracts the locking latch 9 on coaming plate (rear coaming plate 2-2), opens mould. Mold oil evenly is smeared respectively on base plate and coaming plate, close coaming plate, pin 9 is disclosed in insertion locking, then the test specimen of well cutting is put in loading sampling die so that fracture is oppositely horizontal, middle kerf spacing control plate and side seam spacing control plate are inserted in the middle of sample and both sides successively, utilizing the spacing adjusting bolt of rear and front end plate (front splint 4-1, rear plate 4-2) to regulate, make two bat spacing be not more than 5mm, big of brick and mold interval are not more than 3mm; Locking mould side puller bolt, takes out spacing and regulates plate, suitably locking two end plates spacing adjusting bolt, and locks floor and coaming plate with base plate securing bolt, and the die-filling of sample completes.
2. it is in the milk
First the mould having filled sample being placed on operator's console A, utilize grouting spoon to stitch along sample with clean pulp material uniform for stirring compressive strength test and evenly pour into, making slurry evenly flowing rapidly in a mold with leading shovel during perfusion, until filling whole mould.
3. vibrate
Connect shaking table power supply, arranging compressive strength test shaking table time of vibration is 1min, the mould having poured into slurry is placed on shaking table, open shaking table, observe clean pulp material height in vibration processes, and supplement slurry in time, utilize to lead and root out open bubble, it is ensured that clean pulp material fills whole mould. Wait to vibrate automatic stopping, completing mold vibration process.
4. maintenance in early stage
Mould after vibration is statically placed on maintenance platform in early stage, under the not ventilated environment being not less than 7 degrees Celsius, carries out maintenance 20 to 25 minutes in early stage (start time is as the criterion with clean pulp material churning time start of record).
5. the demoulding
The mould that maintenance in early stage is good is placed on stripping operation platform, the base plate securing bolt of mould both sides is unclamped with allen wrench, slowly unclamp mould rear and front end spacing control baffle plate (front splint 4-1, rear plate 4-2), till ultimate compression strength sample resistance to compression face thoroughly departs from mould, unclamp mould two sides puller bolt (left holding device 10-1, right holding device 8-2), a hand pins mould, another hand extracts the locking latch 9 on coaming plate 2-2, slowly open mould, make sample and mould separating. Rooting out the slurry that overlapping section is unnecessary, knockout course completes.
In the later stage, the ultimate compression strength sample after the demoulding is carried out compressive strength test according to national standard related request.
