Mouthful, the inclined-plane 63 of multiple L like shape plates forms the sharp portion 32.
In the above-mentioned technical solutions, first spliced with multiple L like shape plates, the short slab 61 of L like shape plate extend into adjacent thereto
In breach on plank, and the structure of short slab 61 and breach is just matched, and can so make the long slab 62 of adjacent two blocks of L like shape plates
Closely it is stitched together, two L like shape parts is spliced according to the method described above, then by two L like shape portion axial symmetry splicings one
Rise, form a submodule, multiple submodule is all spliced according to the method described above, multiple submodule has just been obtained, tearing open
Except when, it is necessary to be removed successively to both sides from two blocks of L like shape plates of the centre of the submodule of the bottom；
Submodule is again broken down into thinner part, when can further reduce dismounting and pitch lifting surface area, and subtract
Its few cohesion with pitch, reduces bitumen samples deformation, improves the qualification rate that bitumen samples make, at the same can also increase every
Contact area from agent and side plate is bigger, and then increases the recoverable amount of the interleaving agent on side plate, and the dismounting to side plate is more favourable, can
Further to reduce the cohesion of pitch and side plate, the qualification rate that bitumen samples make is improved；
In the breach that the short slab 61 of each L like shape plate is buckled in adjacent L like shape plate, can avoid L like shape plate to
Move at eight word die trial centers, it is ensured that the size of eight type matrix chambers in eight word die trials meets standard；
In another technical scheme, as shown in Figure 1, the side of the bottom plate 1 is relative provided with two alignment pins
11.Alignment pin 11 is oppositely arranged on a side plate, the both sides of eight word die trials can be made to lock simultaneously, eight word die trials are difficult
Deformation, so as to ensure that eight type matrix chambers meet standard size.
In another technical scheme, the submodule be three, the L like shape part by four L like shape plates according to
It is secondary to be spliced.One side plate is divided into 24 pieces of L like shape plate compositions, the qualification rate that bitumen samples make has reached
More than 90%, if being further added by the quantity of L like shape plate, difficulty and the time of eight word die trials of splicing can be increased, drip can be influenceed on the contrary
The producing efficiency of blue or green sample, and L like shape plate number is more, and its section is thinner, yielding, influences the use longevity of eight word die trials
Life, increases use cost.
In another technical scheme, the material of the bottom plate 1, the end plate 2 and the side plate is for copper material or not
Rust steel matter.Due to side plate divide into multiple smaller parts, using copper material or stainless steel, it can be made not variable
Shape, extends the service life of eight word die trials.
In another technical scheme, the roughness of the L like shape plate outer surface is less than 0.1 μm.It is coarse using outer surface
It is closer that L like shape plate of the degree less than 0.1 μm can be such that it is combined when being spliced into side plate, while can also make to form eight type matrix chambers
Side mold portion is more smooth, helps to remove.
In another technical scheme, length difference of the two neighboring submodule along the width of bottom plate 1 is more than 5mm.
The stair-stepping side of side form block formation can be made, ladder width is more than 5mm, so that convenient use people force removes submodule.
Although embodiment of the present utility model is disclosed as above, it is not restricted in specification and embodiment
Listed to use, it can be applied to various suitable fields of the present utility model completely, for those skilled in the art,
Other modification is easily achieved, therefore under the universal limited without departing substantially from claim and equivalency range, this reality
Specific details is not limited to new and shown here as the legend with description.
