Description
Technical field
The present invention relates to construction wall detection research field, particularly to a kind of apparatus and method that body of wall moisture content before heat transfer coefficient detection is adjusted.
Background technology
Building energy conservation includes many aspects, and one of them important step is the heat insulation of construction wall and insulation.And wall heat transfer coefficient is to weigh body of wall whether to reach an important indicator of power conservation requirement, therefore, in body of wall energy conservation project, the design of the heat transfer coefficient of body of wall and check and accept extremely important, correspondingly the detection technique of the heat transfer coefficient of body of wall is required also more and more higher.
Wall heat transfer coefficient detection is generally divided into on-the-spot entity detection and test in laboratory, and test in laboratory is divided into again protective hot box method and demarcates Heat-box method.Although on-the-spot entity detection more can reflect the actual thermal and insulating performance by inspection body of wall truly relative to test in laboratory method, but owing in JGJ/T132-2009 " Residential Buildings Energy examination criteria ", provision 7.1.1 proposes " detection of building enclosure main body section heat transfer coefficient should carry out after being subject to inspection building enclosure to construct at least 12 months ", considering site operation progress and examination cycle, the probability carrying out heat transfer coefficient detection after building enclosure wall construction completes for 12 months again is little.Therefore the acceptance of work is more likely to test in laboratory, but during due to test in laboratory, the body of wall test piece maintenance time is shorter, brick-building art differs, in body of wall test specimen material of main part, moisture content is relatively larger on the impact of thermal characteristic of wall, never determine the relation of quantifier elimination body of wall moisture content and heat transfer coefficient for a long time, the detection of wall heat transfer coefficient is all limited by always to the determination of body of wall drying regime, relevant national standard and provincial standard in thermal characteristic of wall detects also without clearly providing concrete moisture content detection and test specimen regulation scheme simultaneously.To the curing requirements of wall heat transfer coefficient test specimen for must natural curing within more than 28 days, reach to detect under drying regime in DBJ15-65-2009 " Guangdong Province's Code for Acceptance of Construction Quality of Building Energy-saving Engineering " body of wall energy conservation project provision.But to how drying regime defines, and how to make body of wall test specimen reach drying regime and state adjusting method does not all have clear and definite regulation, therefore different control methods is also different to the testing result of wall heat transfer coefficient, and this is totally unfavorable for the examination of body of wall energy conservation project.And GB/T13475-1992 old plant is also suggestion test specimen is adjusted to air dry state before detection, but for In Guangdong Province, 1 year there is the most of the time to belong to wet climates, wanting natural curing to air dry state to need long time, detection excessive cycle is also unfavorable for the control of energy-conservation examination and construction quality.
