Compared with prior art, the utlity model has following characteristics and beneficial effect:

The utility model has overcome traditional moulds from shortcoming great, that cost is high, the form removal assembling process is loaded down with trivial details, has solved the technical problem of increasing work efficiency.

The utility model is take plastics as material, and cost is low, have economic advantages, and from heavy and light, cooperates the holder of diaphragm capsule along design, is conducive to the carrying of mould; In addition, but side of the present utility model is made as the active plugboard of assembly and disassembly, downside and other parts are made as one, active plugboard adopts plug-type fit system and diaphragm capsule to agree with, fastening by locking plate again, the simple structure of whole mould, assembly and disassembly is convenient, shorten the form removal built-up time, improved efficient, and the design that is divided into two of this side that the center is porose, the metal connecting contact of test specimen is placed, between second circular groove, guaranteed that active plugboard can not force in metal connecting contact pre-buried on the test specimen when dismounting, avoided metal connecting contact and test specimen to break away from, guaranteed to shrink the integrality of test specimen.

When the utility model uses, by the design of insertion slot type and fixing of locking plate, making between active plugboard and the diaphragm capsule does not have the slit, concrete casting is injected in the mould again, fully vibrates, through after certain curing period, be collapsible die, during form removal, rotate first locking plate, the active plugboard of dismantling, the air-filled pore inflation demoulding that recycling diaphragm capsule bottom is provided with is taken out test specimen from diaphragm capsule.

The utility model can be widely used in the formation of concrete shrinkage test.
