The existing exterior wall heat-preserving system security performance apparatus for evaluating of China is mainly in standard JGJ 144 " external wall outer insulation engineering rules ", embody the more existing standard of using for reference the Europe and the U.S. of quoting of these establishments of standard among JG 149 " expansion polyphenyl plate thinly plastered external insulation system of outer wall " and the JG 158 " micelle polyphenyl granule exterior wall outer heat preservation system ".Since American-European weather conditions, ambient temperature and humidity, wind-force, duration all is not quite similar with China round the clock, therefore inevitably has problems in the process of implementing.
The utility model content
The purpose of this utility model provides a kind of security of external thermal insulation system of building proving installation, solves the problem that the External Thermal Insulation System proving installation can not adapt to the requirement of Chinese Xia Redong cryogenic region.
The technical solution of the utility model is, a kind of security of external thermal insulation system of building proving installation, it is characterized in that, on the support of weather-proof case basic unit body of wall, built external thermal insulation system experiment model by laying bricks or stones, described weather-proof case is of a size of 4.00m * 2.60m * 1.80m, this weather-proof case carries temperature control and dehydrating unit, described weather-proof case carries water tank and spray equipment, all there is high 2.10m described weather-proof case both sides, the opening of wide 3.10m, be used to install the sample wall, the dimensional requirement of described basic unit body of wall is 2.10m * 3.10m.
The security of external thermal insulation system detect main under laboratory environment the simulating reality external environment condition to the influence of system.The formulation of external thermal insulation system safety experiment scheme in the utility model, main according to two aspect factors: first, the existing outer heat preservation system safety standard of China is main according to European similar standard formulation, and the utility model is to improve on original weatherability experiment basis to the experiment of outer heat preservation system safety test, promptly based on Europe superscript weatherability test experience.The second, the different schemes that experimentize of the German local climate condition of main reference are improved when formulating with Europe superscript at this area.
By contrasting the air temperature distribution for many years of Chinese Xia Redong cryogenic region and Germany, rainfall distributes, and the humidity situation of change has proposed the weatherability experimental provision at the Xia Redong cryogenic region.This device has mainly been adjusted hot rain circulation step in the weatherability experiment, and (existing normal experiment side Ming Reyu experiment period is 80 times, the utility model experiment period is 150 times), by increase, the weather conditions of experimental provision and Xia Redong cryogenic region are complementary to laboratory strength.
The technical solution of the utility model provides a kind of practicable safety test appraisement system for the external thermal insulation system that is fit to Chinese Xia Redong cryogenic region geographical environment and weather conditions.

Embodiment
Be described further for embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the weather-proof casing of experiment at first is installed in the laboratory, keep laboratory temperature at 10 ℃ to 25 ℃, relative humidity is not less than 50%, the regulation and control parameter of weather box, it is 150 times that weather resistant experiment hot rain circle index is set, the regulation and control parameter of weather box is provided with hot rain and hot cold round-robin transition experiment is 20 ℃ of constant temperature, keeps 48h, the regulation and control parameter of weather box, it is 10 times that the weather resistant experiment hot-cold cycle index is set.
Build outer heat preservation system by laying bricks or stones on basic unit's body of wall, test specimen needs maintenance at least 30 days, after maintenance is finished the sample wall is pushed into weather-proof case both sides and is close to, and carries out weather resistant experiment.
After weather resistant experiment is finished, the sample wall is pushed open from the casing both sides, observed the characteristic or the performance change (bubble, peel off, bonding force is lost in the surface detail crack between layers of material, cracking or the like) of total system and finishing mucilage.Experiment is finished after 7 days system is carried out system's tensile strength experiment and system's impact resistance experiment.
External thermal insulation system experiment model has been built in requirement in test by laying bricks or stones on the support of weather-proof case basic unit body of wall, described weather-proof case is of a size of 4.00m * 2.60m * 1.80m.Described weather-proof case carries temperature control system, and temperature regulating range-20 is ℃ to 80 ℃.Described weather-proof case carries dehumidification system, humidity regulation scope 0% to 100%.Described weather-proof case carries water tank and spray equipment, 15 ℃ of water tank water temperature constant temperature.All there is high 2.10m described weather-proof case both sides, and the opening of wide 3.10m is used to install the sample wall.The dimensional requirement of described sample wall is 2.10m * 3.10m.In the described weatherability experiment, hot rain round-robin concrete steps are: 1) casing is heated to 70 ℃ (30min heating-up times), keeps 70 ℃ ± 5 ℃ of temperature, relative humidity 40% (keeping 60min); 2) water spray 30min, 15 ℃ ± 5 ℃ of water temperatures, injection flow rate 1.0L/m
2Min～1.5L/m
2Min; 3) leave standstill 1h.In the described weatherability experiment, hot cold round-robin concrete steps are: keep 48h for 20 ℃ ± 5 ℃ at hot rain experiment back constant temperature; 1) casing being heated to 50 ℃ (60min heating-up times), is 50 ℃ ± 5 ℃ in temperature, and relative humidity is not more than under 10% the condition and places 420min; 2) casing being cooled to-20 ℃ (temperature fall time is 120min), is to place 840min under-20 ℃ ± 5 ℃ the condition in temperature.Here h is hour, and min represents a minute unit, and m represents Mi Danwei.
When adopting the expansion polyphenyl plate system as the utility model security of external thermal insulation system tested object, the tested object overall appearance does not have difference before and after the experiment, does not see obvious cracking, bubbles, and comes off.There is the minority crack at the details position, all is in the float coat surface.
Leave standstill system after the experiment 7 days, and carried out system's tensile strength experiment and system's impact resistance experiment
Table 1 expansion polyphenyl plate system drawing experimental result
Model after adopting the swing type percussion mechanism to the weatherability experiment has carried out system's impact resistance experiment, has carried out 3J and the experiment of 10J two-stage with 500g steel ball and 1000g steel ball respectively, and model has passed through the two-stage experiment, has reached the 10J standard.Expansion polyphenyl plate heat preserving system tensile strength experiment back details such as Fig. 4.
This shows, adopt experimental provision described in the utility model that outer heat preservation system is carried out the security test experience and improved laboratory strength, be in particular in that the minority crack has appearred in the expansion polyphenyl plate system top layer before and after the experiment, and on the established practice experiment model of same producer simultaneous construction, do not find that this crack exists.The while experimental system has been passed through tension experiment and the impact resistance experiment after the weatherability experiment, the section part display system base insulating layer of tension experiment is intact, the laboratory strength of preliminary this experimental provision of proof does not exceed zone of reasonableness, can not occur judging the normal occlusion case system by accident underproof phenomenon.
Based on the above results, prove that the proving installation that the utility model provides is effective and feasible.
