Abstract
The invention relates to a grooved XPS board external wall heat insulation system. The grooved XPS board external wall heat insulation system is laid on an external wall body of a building and sequentially consists of a base layer wall body, polymer bonding mortar, an XPS heat insulation board, a rubber powder EPS particle layer, an alkali-resistant glass fiber mesh fabric, polymer bonding anti-cracking mortar and a finish layer from inside to outside, wherein the XPS heat insulation board is an extruded polystyrene board subjected to surface grooving treatment. By forming V-shaped, U-shaped or rectangular grooves in the external surface of the XPS board to divide the surface of the board into smaller plates, the dispersion and decomposition of temperature stress are facilitated, the thermal losses at grooved positions can be compensated, the stress concentration caused by temperature deformation can also be reduced and the probability that the system is cracked is reduced.
Description
Technical field
The present invention relates to a kind of External Walls Heating Insulation of building, specifically a kind of open flume type XPS plate exterior wall heat-preserving system.
Background technology
Along with carrying out in a deep going way of China's Building Energy-saving Work, the insulation of building is subject to increasing attention.As a kind of principal mode of external thermal insulation system, XPS plate exterior wall heat-preserving system because of its low price, be easy to draw materials, good heat insulating, the advantage such as easy construction, obtain applying more and more widely in construction work.But in practical engineering application, namely some XPS plate exterior insulation works occur crack in a short time, even there is the phenomenon that insulation layer comes off in serious.The cracking of insulation layer not only have impact on the attractive in appearance of elevation of building, and has had a strong impact on heat insulating ability and the durability of heat-insulation system, has influence on the security of the lives and property.
Cause XPS plate exterior wall heat-preserving system to ftracture and have many-sided reason, wherein most importantly XPS plate has the characteristic to variations in temperature sensitivity.XPS plate exterior wall heat-preserving system in the past adopts thin-coat plaster surface layer technique, the thin-coat plaster surface layer heat transfer that variations in temperature causes to external world does not almost have iris action, namely when variation of ambient temperature is more, the hull-skin temperature of XPS plate also changes more, but because XPS plate is to the blocking effect of heat trnasfer, when causing summer, its hull-skin temperature is high and more inside temperature is lower, thus its external surface volume expansion is larger, and its hull-skin temperature is low and more inside temperature is higher during winter, thus its external surface volume contraction is larger, both of these case all can produce concentrated stress, surface layer is caused to ftracture.
Summary of the invention
Easy to crack for XPS plate exterior wall heat-preserving system surface layer in prior art, affect the deficiencies such as the heat insulating ability of heat-insulation system and durability, the technical problem to be solved in the present invention is to provide a kind of simple and easy to do, construction cost is low, high insulating effect, system anti-crack ability strengthen open flume type XPS plate exterior wall heat-preserving system.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Open flume type XPS plate exterior wall heat-preserving system of the present invention, be laid in skin body, be followed successively by from inside to outside: base course wall, polymer bonding mortar, XPS warming plate, rubber powder EPS stratum granulosum, alkali-proof glass fiber mesh, anticracking grout and finish coat, wherein XPS warming plate is the extruded polystyrene board of surface through slot treatment.
Described XPS warming plate external surface is regularly arrange multiple tracks V-shaped groove, U-lag or rectangular channel.
Described V-shaped groove, U-lag or rectangular channel are particles filled by rubber powder EPS.
Described V-shaped groove, U-lag or rectangular channel are evenly arranged in XPS warming plate external surface for laterally and longitudinally interlocking and form square net structure, and V-shaped groove, U-lag or rectangular channel center line are equidistant.
Described V-shaped groove, U-lag or rectangular channel are evenly arranged in XPS warming plate external surface formation prismatic network for staggered, and V-shaped groove, U-lag or rectangle flute profile groove center line are equidistant.
The distance between center line of V-shaped groove, U-lag or rectangular channel is 10 ~ 1200mm.
Or furtherly, the distance between center line of V-shaped groove, U-lag or rectangular channel is 200 ~ 400mm.
Described V-shaped groove, U-lag or rectangular channel are evenly arranged in XPS warming plate external surface formation triangular grid structures for staggered.
The present invention has following beneficial effect and advantage:
1. the present invention is directed to way in the past and produce the reason in crack, by presetting V-arrangement, U-shaped or rectangular channel at XPS plate external surface, plate face being divided into less plate, being conducive to dispersion and dissolving thermal stresses.
2. what XPS plate external surface of the present invention was preset is filled with the stronger rubber powder EPS particle of deformability between V-arrangement, U-shaped or rectangular channel groove, not only can compensate thermal technology's loss at fluting position, the stress that also can reduce because temperature deformation produces is concentrated, and reduces the possibility of system cracking.
3. the present invention slots XPS plate in factory process, is easy to ensure crudy, and the multiple body of wall that to can be used for steel concrete, all kinds of building-blocks etc. be basal plane is applied widely.
