Description
Technical field
The utility model relates to the molding dies that concrete chloride ion examines test specimen, more specifically, it relates to a kind of nothing
Bottom split column die trial.
Background technique
Chloride ion in armored concrete is an important factor for inducing steel bar corrosion, and chloride ion content is excessively high to will affect coagulation
The safety of native component.National present GB/T50082-2009 " Standard for test methods of longterm performance and durability of ordinary concrete mark
It is quasi- " RCM method or electric flux method will all form ￠ 100mm, height 50mm or 100mm in Part VII " chloride-penetration resistance test "
Or 200mm test specimen carries out intensity detection, specimen molding mold general structure is as shown in figure 4, include bed die and cylinder mould, bed die is
Platform is equipped with one and the consistent annular groove of cylinder mould wall thickness, spreads butter in groove and seals, then cylinder mould
Bottom is inserted in groove, recycles connection bolt and cylinder mould outer wall on bed die to lock, then in cylinder mould peripheral wall and bottom wall
Upper brushing thin layer isolation oil, the good material of wet-mixing, which pours into cylinder mould, to be consolidated, and top strikes off standing, is demoulded after maintenance molding.It is de-
Lock bolt is first removed when mould, cylinder mould is taken out from bed die together with test specimen, then pushed up test specimen out of cylinder mould with ingot stripper
It extrudes.If top pressing board is equal with test specimen section, slightly offset in press, i.e., top pressing board can be made to be stuck in cylinder mould, it is difficult to take
Out.Conventional top pressing board is less than test specimen section and is jacked, but during press, and top pressing board edge and cylinder mould inner wall produce test specimen
It is easier to crack inside raw shear stress, especially low-intensity test specimen, reduces later period test piece intensity and examine numerical value.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide it is a kind of solve the above problems it is bottomless
Simplicity, sealing without leakage are torn in split column die trial, spelling open, and demoulding pickup will not cause to damage to test specimen.
To achieve the above object, the utility model provides following technical solution:
Bottomless split column die trial, including be merged by two semicircular cylinders bottomless no top tubular mould, hoop set and
Glass plate, the hoop set bottom surface open up a ring slot, and hoop covers bottom surface and the embedding patch pellosil of annular groove inner wall, hoop set
A venthole is opened in top surface, and venthole is connected to annular groove, and hoop is placed on glass plate, is adsorbed on hoop set from venthole pumping
On glass plate, tubular mould bottom end is inserted into hoop set.
The utility model is further improved scheme, and two semicircular cylinder stitching portions are the zigzag step engagement being mutually twisted
Separation square groove is excavated in face at the joint close of outside, and separation square groove, which is used to that tack bottle opener end to be inserted to rotation and dialled, divides tubular mould.
Zigzag step joint surface makes two semicircular cylinder splicing seams not in same plane, the material that inside pours into before not solidifying not yet
Easily exudation, separation square groove are convenient for separating cylinder mould two halves.
It is that the separation square groove sets up two separately in tubular mould top and the bottom that the utility model, which is further improved scheme,.Upper and lower
Two two are not pushed aside with position rotation, and demoulding is faster.
The further improvement project of the utility model is, the tubular mould outer wall reclines hoop set inner wall.Tubular mould is just
It is stuck in hoop set, the tubular mould of split can be consolidated well, and tubular mould bottom is not easy spillage.
The utility model is compared with the prior art, is had an advantage in that
The utility model tubular type is put together by two semicircular cylinder molds, bottom be inserted into hoop set in, hoop set with
Glass platform is attracted sealing, and assembling splits very simple and fast, demoulding pickup, will not cause to damage to test specimen, ensure that the later period
The accuracy of test piece intensity detection numerical value.
Detailed description of the invention

Fig. 2 is the utility model front view；
Fig. 3 is the A-A cross-sectional view of Fig. 1；
Fig. 4 is existing specimen molding mold structure diagram.
Specific embodiment
As shown in Figure 1 to Figure 3, the utility model includes tubular mould 1, the hoop that bottomless no top is merged by two semicircular cylinders
Set 2 and glass plate 3, the hoop cover 2 bottom surfaces and open up a ring slot 21, and hoop covers 2 bottom surfaces and 21 inner wall of annular groove is embedding
Pellosil 22 is pasted, hoop covers 2 top surfaces and opens a venthole 23, and venthole 23 is connected to annular groove 21, and hoop set 2 is placed on glass plate 3,
Make to form negative pressure in annular groove 21 from the pumping of venthole 23, hoop set 2 is tightly adsorbed on glass plate 3, and the hoop covers 2 internal diameters
Slightly larger than 1 outer diameter of tubular mould, 1 outer wall of tubular mould reclines on hoop 2 inner walls of set, and described two semicircular cylinder stitching portions are to be mutually twisted
Zigzag step joint surface 11, separation square groove 12 is excavated at the joint close of outside up and down, separation square groove 12 is used for tack bottle opener end
Portion, which is inserted rotation and dials, divides tubular mould 1.
Specimen molding operating process:
First hoop set 2 is placed on glass plate 3, makes to form negative pressure in annular groove 21 from the pumping of venthole 23, hoop set 2 is tight
Tightly it is adsorbed on glass plate 3；Two semicircular cylinders are pieced together into a tubular mould 1 again, 1 bottom end of tubular mould is inserted into hoop set
In 2, oil is isolated in 1 inner wall brushing thin layer of tubular mould, then pours into the concrete being stirred in the die cavity of die trial, tamping maintenance
Molding.Tubular mould 1 is first rotated after diel, separates test specimen with glass plate 3, then tubular mould 1 is taken out out of hoop set 2,
It is gently rotated in the end of tack bottle opener insertion separation square groove 12, tubular mould 1 can be split into two halves, easily take out test specimen,
Test specimen will not be damaged.Venthole is in communication with the outside deflation, then hoop set is separated with glass plate.
