Description
Technical field
The utility model relates to concrete strength inspection technology in civil engineering work, particularly a kind of concrete test die being applicable to microwave steam pressure.
Background technology
At present both at home and abroad quick testing intensity of concrete method mainly adopts early strength agent and steam-cured method to accelerate concrete strength development, thus measures intensity when early age strength of concrete calculates its 28 days.Microwave steam pressure maintenance technology changes traditional rapid curing method, uses microwave heating that is efficient, energy-saving and environmental protection, makes concrete test block produce certain intensity in the time short as far as possible, thus measures intensity when early age strength of concrete calculates its 28 days.
Traditional concrete test die one class is the cube die trial that cast iron is made, and comprises the part compositions such as end template, side template baffle shaft, support swing bolt and wing nut, cannot penetrate at microwave steam pressure ring border further aspect microwave; On the other hand due to not sealing, die trial inner concrete moisture under microwave irradiation, is caused to evaporate; Another kind of is the die trial of engineering plastics cube, generally does integrally by engineering plastics bed die and side form, and under microwave steam pressure ring border, microwave can penetrate, but non-refractory high pressure, and under microwave irradiation, cause die trial inner concrete moisture to evaporate equally.The die trial being applicable to test is found to become key technical problem urgently to be resolved hurrily.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides the concrete test die being applicable to microwave steam pressure that a kind of structure is simple, easy to use.
Technical problem to be solved in the utility model is realized by following technical scheme, the utility model is a kind of concrete test die being applicable to microwave steam pressure, be characterized in: comprise bed die, bed die is provided with middle module, the top of middle module is provided with upper mould cover, the inside of middle module is provided with cylindrical mold cavities, the internal thread of module in connection is equipped with in described bed die and upper mould cover, the upper and lower outside surface of middle module is respectively equipped with the external thread with aforementioned screw-internal thread fit, in between two external threads module light outer wall on be fixed with handling block for convenience detach.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, and the described concrete test die being applicable to microwave steam pressure, is characterized in: the cross section of described handling block, bed die and upper mould cover is regular hexagon.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, the described concrete test die being applicable to microwave steam pressure, is characterized in: bottom and the bed die joint of the top of described middle module and upper mould cover joint, middle module are equipped with rubber gasket.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, and the described concrete test die being applicable to microwave steam pressure, is characterized in: described bed die, middle module and upper mould cover are made by nylon material.Overcome conventional steel die trial microwave can not penetrate, yielding shortcoming under common engineering plastics die trial High Temperature High Pressure.
Technical problem to be solved in the utility model can also be realized further by following technical scheme, and the described concrete test die being applicable to microwave steam pressure, is characterized in: the externally threaded rotation direction direction of the upper and lower of described middle module is contrary.
Compared with prior art, the utility model has following effect:
1) be reasonably connected with middle module by upper mould cover, bed die, ensure that the leakproofness of die trial inside, solve the problem of microwave steam pressure ring border lower testing mould inner concrete moisture evaporation.
2) make bed die, middle module and upper mould cover by nylon material, die trial can be made to bear microwave and High Temperature High Pressure, solving steel die trial can not can not the problem of high temperature high voltage resistant by microwave penetration and engineering plastics die trial;
3) rational in infrastructure, facilitate form removal, the demoulding.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the structural representation of middle module.
Embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
With reference to accompanying drawing 1 and Fig. 2, a kind of concrete test die being applicable to microwave steam pressure, comprises bed die 3, and bed die 3 is provided with middle module 2, and the top of middle module 2 is provided with upper mould cover 1.Bed die 3, middle module 2 and upper mould cover 1 are made by nylon 66 material.Its good heat resistance, although traditional steel die trial high-temperature-resistant high-pressure-resistant, microwave can not penetrate, and common engineering plastics die trial can not high temperature high voltage resistant, and the concrete test die adopting nylon material to make solves the problem of microwave and steam pressure two aspect.
As shown in Figure 2, the inside of middle module 2 is provided with cylindrical mold cavities, the internal thread of module 2 in connection is equipped with in described bed die 3 and upper mould cover 1, the upper and lower outside surface of middle module 2 is respectively equipped with aforementioned screw-internal thread fit and the contrary external thread 4 of rotation direction, between two external threads 4 module 2 light outer wall on be fixed with handling block for convenience detach.The cross section of handling block, bed die 3 and upper mould cover 1 is regular hexagon, uses hexagon steel spanner conveniently can realize the dismounting of bed die 3 and upper mould cover 1 like this.Middle module 2 is placed on ingot stripper can realize the demoulding quickly and easily.Bottom and bed die 3 joint of the top of described middle module 2 and upper mould cover 1 joint, middle module 2 are equipped with rubber gasket.Use rubber gasket to add to be threaded, ensure that the leakproofness of die trial inside, microwave irradiation lower testing mould inner concrete moisture can not evaporate again.
During die trial, first tear upper mould cover 1 and bed die 3 open with hexagon steel spanner, in the groove of upper mould cover 1 and bed die 3, load onto rubber gasket, then load onto bed die 3 with hexagon steel spanner, after putting the oil in middle module 2 casting concrete, load onto upper mould cover 1 with hexagon steel spanner; After die trial being tested, pull down upper mould cover 1 and bed die 3 with hexagon steel spanner, middle module 2 is put on ingot stripper and takes out concrete test block, cleaning die trial.So far die trial is finished using.
