Description
Technical field
The present invention and a kind of building implement are specially a kind of portable energy-saving concrete test cube protection box.
Background technology
The building engineering construction scene all needs to do concrete test block at present, and concrete test block needs standard curing can carry out the compression strength check in 28 days, and the standard curing temperature is 18-22 ℃ between curing period, and humidity is not less than 95%.And concrete curing is to make concrete performance obtain the important means of optimum state.In order to make experimental result more fast and accurately, just need in being tried the maintenance processes of concrete block, be subjected to than maintenance in higher quality, and maintenance at present all adopts on-the-spot brick or concrete now to do a maintenance pond, is furnished with electron temperature-control and humidification apparatus in the maintenance pond.And that the technical staff finds that in long-term practice process this maintenance pond is influenced by external condition is bigger, as having a power failure, personnel's negligent supervision can both cause concrete test block temperature and humidity in curing cycle to change, thereby make concrete test block inaccurate at last in the data that finish to obtain after the test, can not the concrete intensity of actual response.
Summary of the invention
The present invention causes the inaccurate problem of final data in order to solve the external condition control difficulty that exists in the concrete test block maintenance that exists in the prior art and a kind of portable energy-saving concrete test cube protection box is provided.
The present invention is realized by following technical scheme, a kind of portable energy-saving concrete test cube protection box comprises casing, and the internal layer that skin that casing is made by polythene material and polythene material are made is formed, it between skin and the internal layer void layer, outer layer thickness 10mm, interior layer thickness 5mm, the thickness of void layer are 15mm, it is 1 of 90-95% that concentration is housed in void layer, the 3-butanediol aqueous solution, 1, the volume ratio that 3-butanediol aqueous solution volume and casing internal layer comprise is 1: 10-15.The long 1100mm of casing, wide 550mm, high 220mm.This technical characterictic can satisfy the requirement that holds concrete test block, can satisfy 1 again, and the requirement of 3-butanediol amount of aqueous solution used makes it to be in all the time thermoregulator optimal volume state.
Operation principle of the present invention has at first been used polythene material, its heat conductivility is moderate, the interior bed thickness of skin, helping heat keeps not distributing, and the requirement that the heat that internal layer can satisfy preferably and casing is interior transmits, the butanediol of certain proportion amount makes the temperature in the case can remain on variation between 18-22 ℃ all the time, has satisfied the detection requirement of concrete test block fully, and it is in light weight, be easy to carry, can be used as the conventional tool of detection, be not affected by the external environment, improved processing safety, reduced the concrete test block difference that human factor causes in maintenance processes, its conveniently moving of while, light weight, be convenient to unified management, the recycling rate of waterused height.
