Description
Technical field
This utility model belongs to building material technical field and in particular to a kind of body of wall self-conserving heat plate.
Background technology
China's building energy conservation level is far below developed country, and the unit area energy consumption of building is still the 3- of close developed country
5 times, therefore energy-conservation is a fundamental state policy of China, country encourage development assembled architecture it is stipulated that 13 during body of wall sections
Standard can bring up to 75%, wherein Development of Novel wall heat insulation material, solve material thermal and insulating performance, improve building enclosure from
Heat-insulating property is one of emphasis developing direction.
About three kinds of wall thermal insulating mode at present, brick mix structure, frame structure and architectural lay wire structure.Traditional brick mixes
Structure uses clay brick, is difficult to meet the requirement to building structure requirement energy-conservation for the today's society, and the thickness of body of wall is larger；Framework
Structure wall can be filled with small concrete block and structural clay tile, but itself heat-insulating property of little building block poor in addition it is also necessary to
In addition adopt Insulation, the waste of the energy and resource can be caused；Architectural lay wire is due to directly pasting 50 100mm outside
The heat-insulation layers such as thick heat-insulation plate for external, but after so plastering outside, it is easily caused protective layer cracking, and the risk that comes off exists, with
When two pieces of lay wire stitching portions due to contact leakiness, be easily caused cold bridge phenomenon.
China is used for industrial heat preservation and the Conventional insulation species of building heat preservation is more, and such as air entrained concrete and foam mix
Solidifying soil is the novel energy-saving environment-friendly type construction material of current wide popularization and application, the bubble as disclosed in patent cn201010264056
, although heat conductivity is relatively low, heat insulation effect is preferable for foam concrete sheet material, but the filling of going along with sb. to guard him that purposes is limited only to building field is tied
, also there is certain defect in the materials for wall of structure, such as low strength, cracking, water suction etc., often wall body slit, or
Cold-heat bridge in gap between two boards, and causes seepage, the quality problems such as wall plastering hollowing, cracking by crack.
Clay haydite light weight, good endurance, thermal and insulating performance project, and therefore clay brick becomes good wall thermal insulating
Material, but clay haydite produces and consumes that the energy is huge, environmental pollution is serious, and there is a problem of relatively costly, therefore its
Using not obtaining significant progress and good popularization.
The application documents of patent application cn201010489490 disclose a kind of decorative heat preservation integral light concrete slab
Material, is made up of concrete heat insulation layer and architectural concrete surface layer, and heat conductivity, between 0.1-0.15w/m.k, has certain guarantor
Warm nature energy, but the performance such as its comprcssive strength and durability is all low, is suitable only for as heat-insulation layer sheet material.
The insulation supplementary material using at present, has no and accomplishes the autologous heat preservation energy-saving of walling 75% standard it is necessary to additional insulation
Layer, time-consuming bothersome, disadvantage is the more.
Utility model content
