Background technology
Owing to having the features such as speed of application is fast, quality good, saving is artificial, easy construction, pump concrete the most gradually becomes
For in concrete construction conventional kind, it is widely used in general room and builds structural concrete, road concrete, large volume
The engineering such as concrete, skyscraper.But owing to pump concrete has preferable fluidity, therefore may in work progress
The problem that there will be laitance, particularly at present extensively mixed with flyash in pump concrete, when concreting jolt ramming operation
How many all some laitances in surface, the usual fly ash of concrete that strength grade is the highest is more, and the ratio of mud is relatively big, and laitance is the most more
Seriously.If these laitances are not removed, the laitance layer that one layer of intensity is the lowest can be formed on coarse aggregate layer surface after hardening, have a strong impact on
The performance of concrete.
It is used for measuring the instrument of concrete laitance layer thickness currently without special, characterizes laitance thickness the most artificially
Subjective estimation, fluctuation is big, it is judged that inaccurate, is unfavorable for the carrying out of subsequent construction.
Utility model content
In place of the purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of easy concrete laitance
Layer thickness test device, can directly measure the thickness of laitance layer, can reduce the subjective impact of tester during test, it is provided that be accurate
Test data the most reliably, and method of testing is the most easily operated, for additive performance and the concrete construction of concrete
The research of energy has great importance.
This utility model solves its technical problem and be the technical scheme is that
A kind of easy concrete laitance layer thickness testing device, including:
Horizontally disposed test board, it is evenly distributed with some confession laitances and flows through and intercept the through hole of coarse aggregate；
Scale bar, is vertically fixed on test board；This scale bar on the basis of the plane of test board lower surface place under
And it is provided with graduation mark；
Level indicator, is vertically fixed in scale masthead portion；
Cooperated by level indicator, scale bar and test board so that this test device falls to coarse aggregate in laitance layer
In layer top, and dropping process, this test board keeps level, and records laitance layer thickness by graduation mark.
In one embodiment: the buoyancy that test device is produced by the gravity of described test device more than laitance.
In one embodiment: described through hole is circular hole or the square hole of the length of side 4.5～5mm of diameter 4～6mm.
In one embodiment: described test board is circular, and its thickness is less than 2.5mm, and diameter is not less than 14cm.
In one embodiment: described test board is that hard material is made.
In one embodiment: described test board is that rustless steel is made.
In one embodiment: described level indicator is air-bubble level.
In description of the present utility model, it is to be understood that term " on ", D score, "front", "rear", "left", "right",
Orientation or the position relationship of the instruction such as " horizontal ", " erecting ", " top ", " end ", " interior ", " outward " are based on shown in the axonometric chart in accompanying drawing
Orientation or position relationship, be for only for ease of and describe this utility model and simplify description rather than instruction or the dress of hint indication
Put or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this utility model
Restriction.
The technical program is compared with background technology, and it has the advantage that
1, this utility model simple in construction, low cost of manufacture.
The levelness of test board when 2, ensure that this utility model falls by level indicator, it is to avoid this utility model whereabouts
Time deflection and the measurement error that causes.
3, this utility model can directly measure the thickness of laitance layer, can reduce the subjective impact of tester during test,
Unfailing test data are provided, and method of testing is the most easily operated, for additive performance and the concrete of concrete
The research of workability has great importance.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is concrete laitance layer thickness testing device overall appearance schematic diagram of the present utility model.
Fig. 2 is concrete laitance layer thickness testing device schematic top plan view of the present utility model.
Reference: test board 1, scale bar 2, air-bubble level 3, through hole 4.
Detailed description of the invention
Content of the present utility model is illustrated below by embodiment:
Refer to Fig. 1 and Fig. 2, the easy concrete laitance layer thickness testing device of one, including:
Circular test board 1, by rustless steel or other there is certain degree of hardness and be not susceptible to the hard material of deformation and make,
Its thickness is less than 2mm, and diameter is not less than 15cm；Be evenly distributed with some through holes 4 on this test board 1, for diameter 5mm circular hole or
The square hole of length of side 4.75mm, the size of these some through holes 4 is just available for laitance and flows through, but coarse aggregate not may pass through；
Scale bar 2, is vertically fixed on test board 1；This scale bar 2 is on the basis of the plane of test board 1 lower surface place
It is provided with corresponding 0 graduation mark of graduation mark, i.e. test board 1 lower surface place plane from bottom to top；
Air-bubble level 3, is vertically fixed in scale bar 2 top.
The buoyancy that test device is produced by the gravity of this test device more than laitance.
This utility model onsite application mode is as follows:
The container that fresh concrete internal diameter to be measured is bigger than test board 1 of the present utility model installs, and places level, by this reality
It is placed in above fresh concrete with novel so that test board 1 lower surface just contacts the upper surface of concrete, hand-held bubble level
Instrument 3 adjusts this utility model and makes air-bubble level 3 be shown as level, i.e. makes test board 1 also holding level；After Wen Ding, prominent
So decontrol test device of the present utility model so that it is in vertical drop, and dropping process, this test board 1 keeps water in laitance layer
Flat；Along with the whereabouts of test board, the through hole 4 that laitance gradually passes through on test board 1 flows to above test board 1；When test board 1 falls
When touching coarse aggregate to laitance layer, owing to coarse aggregate cannot pass through through hole 4, therefore test device stops falling, now
Scale bar 2 reads the scale value that when it stops falling, the upper surface of concrete is corresponding and is the laitance thickness of concrete to be measured
Degree.
The above, only this utility model preferred embodiment, therefore can not limit what this utility model was implemented according to this
Scope, the equivalence change i.e. made according to this utility model the scope of the claims and description and modification, all should still belong to this practicality new
In the range of type contains.
