Description
Technical field
The invention belongs to building enclosure technical fields, are specifically a kind of architectural exterior-protecting construction wind resistance safety and watertightness
Experimental rig and method.
Background technique
Since reform and opening-up, Building Trade in China develops at a speed unheard of before, and China town and country are completed total every year at present
Construction area has reached hundred million or so, and especially high-rise and super high-rise building pulls out in major, the middle city in the whole nation like the mushrooms after rain
Ground and rise.Peripheral structure in building mainly suffers from the effect of wind and rain.On the one hand, with the increase of depth of building, wind
Load action is more obvious, and numerical value is up to one of the important motivity load acted in structure is become, since the factor of wind is made
At architectural exterior-protecting construction by commonplace the case where destruction.For example, a phenomenon that enclosing wall collapses is consolidated in Lanzhou west, cause
9 passerbys are pounded, and reason is that occurred instantaneous battle array strong wind at that time, and building enclosure does not pass through Specialty Design, by powerful
It is destroyed after the effect of wind load, to collapse.It can be seen that a kind of method for proposing wind resistance safety for examining building enclosure
It is highly desirable.
On the other hand, building enclosure is also subject to the impact of vapor and rainwater in air, and wall absorbs after moisture
It can cause the decline of construction material thermal insulation property, strength reduction, mildew.It goes along with sb. to guard him under long-term hot wet condition effect, also will cause
The softening of gypsum material, dusting, iron or corrosion of steel structure, can also breed along with a large amount of mushrooms, pollute indoor environment.It can be seen that building
Build the dampness of building enclosure not only for the service performance of building structure and security presence huge threat, and it is long-term by
