Description
Technical field
The utility model relates to a kind of shaping mould that the concrete thermophysical parameter is measured test specimen of making, comprise that concrete specific heat capacity, thermal diffusivity, coefficient of heat conductivity measure the shaping mould of used test specimen.
Background technology
Concrete specific heat capacity (also claiming specific heat), thermal diffusivity (also claiming thermal diffusivity), coefficient of heat conductivity etc. are the important component parts of concrete thermophysical parameter; These thermophysical parameters are major parameters of distribution of decision concrete internal temperature and variation characteristic; Be related to the temperature stress distribution character of inside concrete, thereby be that mass concrete engineering design and control mass concrete internal temperature stress control concrete temperature cause the important parameter that splits.The assay method of the different thermophysical parameters of concrete or the standard of different testing apparatuss are different to the shape need of detected concrete test specimen.Like (SL352-2006) defined of People's Republic of China's water conservancy industry standard " concrete for hydraulic structure testing regulations ": the test specimen that concrete specific heat capacity, coefficient of heat conductivity are measured is shaped as: it is the via hole of 40mm that the diameter with spigot shaft coaxle is arranged in the middle of the right cylinder test specimen of diameter 200mm, high 400mm, test specimen; The test specimen that thermal diffusivity is measured is shaped as: the right cylinder test specimen of diameter 200mm, high 400mm, it is the temperature survey hole of 200mm for the 10mm degree of depth that diameter is arranged on the test specimen central axis.And for example the test specimen that adopted of some specific heat capacity determinator is shaped as: it is the via hole of 60mm that the diameter with spigot shaft coaxle is arranged in the middle of the right cylinder test specimen of diameter 200mm, high 400mm, test specimen.(application publication number: the specific heat capacity that CN102033080) is adopted is measured test specimen and is shaped as: the right cylinder test specimen of diameter 200mm, high 400mm, it is the temperature survey hole of 200mm for the 10mm degree of depth that diameter is arranged on the test specimen central axis to also have Chinese invention patent application " assay method of concrete specific heat capacity ".For difform test specimen, its shaping mould is also inequality.For profile is cylindrical test specimen, and the structure of its shaping mould adds base by a tubulose external mold and forms, and external mold is metal tube (steel pipe, iron pipe) normally, and the internal diameter of metal tube is identical with the diameter of right cylinder test specimen; Also there is external mold to process, fixed mechanism arranged between two half modules to form tubular structure with the metal tube that is divided into two half modules through axis; Base is a metal plate; Between external mold and the base fixed mechanism is arranged.
When in the middle of the test specimen through hole being arranged, then also have a support in the external mold upper end, there is one to be the hole of through-hole diameter on the support with the coaxial diameter of external mold, base also has one to be the hole or the cave of through-hole diameter with the coaxial diameter of external mold; Other has an internal mold, and internal mold is that diameter is the metal tube or the metal bar of through-hole diameter, and clearance fit is made in the hole of internal mold two ends and support or the hole of base or cave.And when obstructed on earth hole was arranged in the middle of the test specimen, on base atresia or the cave, support was consistent with structure when there is through hole the test specimen centre, control in addition on the support internal mold insertion test specimen degree of depth detent mechanism and with support on interporal lacuna cooperate.
When making test specimen, suitable for reading through external mold, the space through support and outer intermode when support is arranged pours into the concrete that stirs in shaping mould, and moulding is smash in shake again.Then in the test specimen maintenance processes, need rotate certain angle at set intervals during if any internal mold, can't from test specimen, take out with the concrete coagulation that prevents to be cured.
Can know that from above-mentioned situation prior art is when measuring the concrete thermophysical parameter of difference, the difference of its test specimen then needs different dies.That is to say, when said three thermophysical parameters are measured, need dispose the different particular manufacturing craft of three covers the most for a long time.Even if under the situation of unified specification, also need a plurality of bases and support, can cause waste and increase operational trouble.
Summary of the invention
To above-mentioned deficiency, the utility model is exactly to provide a kind of mold that only disposes just can make the shaping mould that different concrete thermophysical parameters are measured needed making concrete thermophysical parameter mensuration test specimen.
