Technical field：
The present invention relates to construction engineering technical fields, and in particular to a kind of prefabricated no heat bridge heat preservation of rectangular steel pipe keel is outer
Wall and preparation method thereof.
Background technology：
As expressway around city develops, building energy consumption increases year by year, more and more assembled architectures and green construction method
It is put on the agenda, as the key industry of national sustainable development, building energy conservation industry is the important of realization national energy security
Approach.The passive room of assembled be one kind using concrete prefabricated element as building enclosure, heat insulating effect and air-tightness are good,
Indoor comfort degree is high, does not use the novel house of active heating technology.Either from the construction period in house and construction quality,
Or all it is extremely to meet current Building Trade in China developing direction from the point of view of the indoor comfort degree and energy consumption angle built after building up
's.
Wall is under construction as the main partition member in space, and its heat insulation property directly affects adopting for building
Warm energy consumption for cooling, thus the heat insulation effect of wall to the whole heat preservation of building and it is energy saving be vital.At present, China's tradition
Building heat preservation be after the completion of the construction of building main body, paste external thermal insulation, but this heat-preserving wall in outside vertical surface of building
Form of construction work have the shortcomings that piece is more, easy to fall off, heat bridge is big, globality poor, therefore existing wallboard be difficult to meet low energy consumption,
The design of no heat bridge needs, and reinforced concrete wall is rigidly too strong, under horizontal force action, between wallboard and wallboard easily
The fissure of displacement is generated, is unfavorable for the guarantee of air-tightness and water resistance, with the continuous promotion of China's building energy-saving standard, especially exists
Under " no heat bridge " theory requirement of German passive room building, how to design a kind of prefabrication, can polylith combination assembling, low energy
