Abstract
The utility model discloses a low temperature cohesiveness test device of pitch and building stones, including support and install the sleeve on the support, be provided with the steel sheet of installing on the base telescopic under, the steel sheet on be equipped with and fall into the tabula net that the square of building stones was placed in the same being used for of a plurality of areas with the steel sheet. Compared with the prior art, the utility model utilize the tabula net on sleeve and the steel sheet, can avoid on the invar board the inhomogeneous or steel ball of building stones interval can not accurately fall steel sheet center department, influence the steel ball and shake the quantity that the falling rocks is expected to bring great error for the test result, can effectively improve experimental precision, for can accurate definite pitch providing reliable foundation with the low temperature bond property of building stones.
Description
Technical field
The utility model relates to actual road test detecting instrument field, is specifically related to the low temperature bonding test unit of a kind of pitch and building stones.
Background technology
The low temperature bonding of pitch and building stones tests the low temperature bonding performance being applicable to evaluate pitch and modified bitumen and building stones.Building stones uniform adhesion on the steel plate smearing pitch to be measured, makes steel ball impact steel plate under specified altitude, with the rubble number percent fallen by shaking to evaluate its low temperature bonding performance by test.When testing under traditional test unit, may occur, because building stones spacing on steel plate is uneven or steel ball can not accurately fall steel plate center, affects the quantity that steel ball shakes off building stones, thus bringing comparatively big error to test findings.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of and effectively can improve the pitch of test findings degree of accuracy and the low temperature bonding test unit of building stones.
For achieving the above object, the technical solution adopted in the utility model is: comprise bearing and be arranged on the sleeve on bearing, immediately below sleeve, be provided with the steel plate be arranged on base, described steel plate is provided with and steel plate is divided into the identical tabula net being used for placing the grid of building stones of some areas.
Steel plate is divided into 100 identical grids of area by described tabula net.
Described base is Height Adjustable telescopic structure.
The utility model compared with prior art utilizes the tabula net on sleeve and steel plate, can avoid because building stones spacing on steel plate is uneven or steel ball can not accurately fall steel plate center, affect the quantity that steel ball shakes off building stones, thus bring comparatively big error to test findings, effectively can improve test accuracy, for accurately determining that the low temperature bonding performance of pitch and building stones provides reliable basis.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model steel plate.
Wherein, 1, steel ball; 2, sleeve; 3, steel plate; 4, base; 5, bearing; 6, tabula net; 7, grid.
Embodiment
Below in conjunction with accompanying drawing, structural principle of the present utility model and principle of work are described in further detail.
As depicted in figs. 1 and 2, the utility model comprises bearing 5 and is arranged on the sleeve 2 on bearing 5, sleeve 2 makes steel ball 1 can fall along it, immediately below sleeve 2, be provided with the steel plate 3 be arranged on base 4, steel plate 3 is provided with and steel plate is divided into the identical tabula net 6 being used for placing the grid 7 of building stones of 100 areas.
Wherein, base 4 is Height Adjustable telescopic structure, can ensure that steel ball impacts steel plate under the height of regulation.
The utility model in use, carries out according to following operation steps:
Step 1, before the test is conducted, place bearing and base;
Step 2, on steel plate, build the pitch of definite quality, building stones to be measured are placed in grid, steel plate and building stones are put into 60 DEG C of baking oven 5h, then put into the refrigerator 24h of-18 DEG C;
Step 3, the steel plate taken out from refrigerator is placed on base, makes not glue facing up of building stones, adjustment substructure height and position, make bushing core aim at steel plate central authorities and bearing podium level to the distance of iron plate plane is 50cm
Step 4, steel ball being placed on bearing platform edges, touching steel ball, steel ball is fallen along sleeve, just fall at steel plate center, calculating the rubble number percent that fallen by shaking to evaluate its low temperature bonding performance.
The utility model utilizes the placement of the grid in tabula net building stones to make building stones spacing even; Sleeve is utilized to make steel ball along its free-falling to steel plate center, can effectively avoid because of building stones skewness, steel ball can not accurately fall steel plate center, affect the quantity that steel ball shakes off building stones, comparatively big error is brought to test findings, thus for judging that the low temperature bonding performance of pitch and building stones provides reliable basis.
