A kind of sandwich thermal insulated structure composite plate of external wall
Technical field
The present invention relates to a kind of sandwich thermal insulated structure composite plate of external wall, belong to building field.
Background technology
In order to save the energy, it is achieved the strategy and policy of sustainable development, the Chinese government carries out energy saving building by force, and Shandong Province takes the lead in from original energy-conservation 65%, building standard is brought up to energy-conservation 75%.At present, the major way of China's building energy conservation is: external wall outer insulation, and it is mainly " exterior insulation system for polyphenyl plate thin plastering exterior wall " and cast-in-place build sandwich polyphenylene heat insulation slab body of wall two ways.Owing to China's the South and the North climate difference is very big, the problem come out is quite a lot of.Be mainly manifested in: outer wall cracking, external thermal insulation come off, heat-insulation layer poor durability, fire protecting performance are poor, not with building with problems such as life-spans.Beijing is in order to solve the technical problem that Current Building ' thing exterior-wall heat insulation exists, adopt and outside the building place polyphenylene heat insulation slab outside wall, build thickness again in the outside of polyphenylene heat insulation slab by laying bricks or stones and be 90mm normal concrete building block or thickness is the decorative buiding block of concrete of 115mm, form a kind of sandwich thermal insulated Architectural Construction of exterior wall, but, this kind of insulated pouring structure there is also some problems or deficiency: one be polyphenylene heat insulation slab is free state, not being connected with skin and concrete segment, only the joist by every layer carries out load capacity;Two is plant tension rib on wall face too much, and difficulty of construction increases;Three is that building block weight is big, and the load on basis increases, and building cost increases;Four is that the building construction cycle is long, needs jointing and processing cost of plastering to increase outside building block, and construction period extends.A kind of sandwich thermal insulated structure composite plate of external wall, it it is a kind of novel external wall heat insulating material for external with assembling type functional, according to south and north, the heat transfer coefficient of the exterior enclosure wall of building is required difference, the thickness of hard polyaminoester warming plate can be increased, realize factorial praluction, site operation standardization.Use the building that this kind of composite plate is built, not only can reach the building energy-saving standard of regulation, but also overcome critical defect that the current art schemes such as existing external wall outer insulation exist, that cannot overcome.A kind of sandwich thermal insulated structure composite plate of external wall, this kind of sandwich thermal insulated structure composite plate of external wall, both it is suitable for the Winter protection of northern China, the summer being also suitable south China is heat insulation, has the extensive adaptability of south and north.It is not only applicable to the exterior wall of frame structure, is also adapted to frame-shear structure exterior wall, reach the index of energy-conservation 75%.Visible, a kind of sandwich thermal insulated structure composite plate of external wall, there is insulation with structure-integrated, insulation material and building, with the feature in life-span, meet the regulation of new edition " Code for fire protection design of buildings " 50016-2014, have extremely wide market prospect.
The present invention attempts to solve thermal insulation dehiscence that the building heat insulation systems such as existing external wall outer insulation in use exist, comes off, poor durability, easy breaking out of fire, not with building with difficult problems such as life-spans.
Summary of the invention
