Abstract
The invention discloses a block fixing device for a ductility test. The device comprises a bottom plate and a top plate, wherein surfaces of the bottom plate and the top plate are level and smooth; a ductility test mold is placed between the top plate and the bottom plate which are arranged in place and is fixed by four screws in the vertical direction, so that the ductility test mold cannot move in the vertical direction; a side mold baffle is arranged at a side mold on the bottom plate, so that the ductility test mold cannot move horizontally; in addition, three drilling holes are formed in the top plate, asphalt can be poured in the device and can overflow through the three drilling holes, four top plate screw holes are formed in positions, which correspond to the bottom plate, of the top plate, and therefore, the top plate, the bottom plate and the ductility test mold positioned between the top plate and the bottom plate can be fixedly connected through the screws and nuts. The block fixing device for the ductility test is simple in structure and convenient to process, a sample of the ductility test can be fixed with the top plate and the bottom plate, so that the sample cannot deform, levelness and smoothness of the upper surface and the lower surface of the sample are guaranteed further, test precision is improved, and a test process is convenient and speedy.
Description
Technical field
The invention belongs to field of road, keep off fixing device particularly to a kind of lattice for ductility test.
Background technology
Ductility is one of Colophonium three norms, and indoor ductility test method is efficient and convenient, and result treatment is simple, is widely used in scientific research and engineering practice.It is currently mainly used ductility machine and standard eight type matrix is tested.Test apparatus itself does not has defect, but in filling mold process, it is difficult to ensure that the flat smooth of sample upper and lower surface.Summed up by lot of experiments, die trial can be placed on the sheet glass of surface smear interleaving agent, it is possible to ensure that test specimen lower surface smooths；When Colophonium is full of eight type matrixes, unnecessary Colophonium can overflow from top.Doctor blade upper surface by heat, during abecedarian Guan Mo, too much Colophonium is overflowed because controlling the bad amount of pouring in metropolis, waste material, even if veteran operator, scraping off unnecessary Colophonium also can occur Colophonium disorderly to spatter phenomenon, easily scald people, and whole operating process easily makes sample deformation, thus affect test accuracy.For solving the problems referred to above, the present invention intends providing a kind of lattice for ductility test to keep off fixing device, and this thinking has no that document is reported at present.
Summary of the invention
It is an object of the invention to provide a kind of lattice for ductility test and keep off fixing device, to solve the problem mentioned in above-mentioned background technology, thus improve ductility test precision, improve test reasonability.
The thinking of the present invention: make ductility die trial that vertical direction displacement and horizontal displacement can not occur by a kind of lattice gear fixing device；This device is provided with Special drill and is respectively used to pouring into and overflowing of Colophonium simultaneously, it is achieved the easy cleaning being precisely controlled and overflowing Colophonium of the Colophonium amount of pouring into.
The present invention is achieved in that
nullA kind of lattice for ductility test keep off fixing device，Including base plate and top board，The two equal flat smooth in surface，It is welded with the side form baffle plate of two panels opposition on base plate and is provided with four base plate screw holes，Two panels side form baffle plate fills the transverse shifting of ductility die trial side form in mold process for limiting，Ductility die trial is placed in and is between the top board to folded position and base plate，The position, axis of top board arranges three borings，It is respectively two asphalt overflowing holes being in symmetric position and a Colophonium in an intermediate position pours into hole，Asphalt overflowing hole is positioned at eight word radiuses of ductility die trial，Spilling voluntarily during for pouring into Colophonium excess，Colophonium pours into hole and is positioned at the minimum transverse section of ductility die trial，Colophonium pours into hole by funnel from Colophonium and flows into ductility die trial，Additionally，Position the most corresponding with base plate on top board is provided with four top board screw holes，Fixing top board can be connected by screw and nut、Base plate and the ductility die trial being between them.
The bottle neck diameter of described funnel pours into hole with the Colophonium that can just insert top board and is as the criterion.
The lattice for ductility test of the present invention keep off the simple in construction of fixing device, convenient processing, and the sample of ductility test can be fixed together with top board and base plate, sample is made not have deformation, further ensure the flat smooth of sample upper and lower surface, test accuracy is improved, and process of the test becomes convenient and swift.

Detailed description of the invention
Below in conjunction with accompanying drawing, presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be more easy to be understood by user, thus protection scope of the present invention is made apparent clear and definite defining.
Embodiment:
A kind of lattice for ductility test keep off fixing device, including base plate and top board, the two equal flat smooth in surface, it is welded with the side form baffle plate 2 of two panels opposition on base plate and is provided with four base plate screw holes 1 and 3, ductility die trial is placed in and is between the top board to folded position and base plate, two panels side form baffle plate 2 contacts with the side form of ductility die trial, limits and fills the transverse shifting of side form in mold process, thus ensures the integrity that sample irrigates；The position, axis of top board arranges three borings, it is respectively two asphalt overflowing holes 4 and 4` being in symmetric position and a Colophonium in an intermediate position pours into hole 5, asphalt overflowing hole 4 and 4` is respectively positioned at eight word radiuses of ductility die trial, Colophonium pours into hole 5 and is positioned at the minimum transverse section of ductility die trial, additionally, position the most corresponding with base plate on top board is provided with four top board screw hole 1` and 3`, it is possible to connect fixing top board and base plate by screw and nut.
The lattice for ductility test of the present embodiment keep off fixing device and follow the steps below use:
