Description

A kind of no cavity complex heat-preservation breaks heat bridge structure body and construction method
Technical field
The invention belongs to construction engineering technical field, more particularly to a kind of no cavity complex heat-preservation break heat bridge structure body and Construction method.
Background technology
It refers to the armored concrete being in the building enclosures such as exterior wall and roofing or beams of metal/column/rib/accessory to build heat bridge Equal positions, since the heat-transfer capability at these positions is strong, hot-fluid comparatively dense, internal surface temperature is relatively low, therefore referred to as heat bridge.
Building exterior wall heat preserving is the important component of building energy conservation, while being also the important component of building fire protection, And the thermal insulation material that building exterior wall heat preserving uses can be divided into A grades of thermal insulation materials and B grades of thermal insulation materials, if it is using A grades of heat preservations Material can then cause building exterior wall heat preserving cost to increase, and if it is using B grade thermal insulation materials, and can cause potential problem of preventing fires.
For this purpose, it is specified that the thermal insulation material used when external wall and both sides in the Code for fire protection design of buildings in China When wall is constituted without cavity compound insulation structure body, the fire endurance of the structure should meet codes and standards, and propose as guarantor When the combustibility of adiabator is B1, B2 grades, thermal insulation material both sides wall should use incombustible material, and thickness is no less than 50mm。
With the continuous promotion of China's building energy-saving standard, the reason especially in building " big thickness heat preservation " and " no heat bridge " It reads under requiring, a kind of insulation structure for a building exterior wall for not only having met heat preservation energy-saving standard but also having met fire protection requirement of exploitation seems particularly heavy It wants.
