Description

A kind of outer wall thermal insulation system
Technical field
The utility model relates to a kind of parts of building, particularly relates to a kind of heat-insulation system that is used for skin, can play effect heat insulation, sound insulation.
Background technology
Along with improving constantly of people's living standard, also more and more higher to the requirement of habitat condition, building trade constantly develops to energy-saving and environmental protection, comfortable direction.External Thermal Insulation Technology for External has been subjected to countries in the world and has paid close attention to widely.External Thermal Insulation Technology for External can be avoided building cold bridge, heat bridge, avoids outer surface of wall dewfall in winter, can protect agent structure, reduce thermal stresses, thereby increase structural life-time.Just because of the outstanding energy-saving effect of external wall outer insulation, develop very rapid.
The research and development of China in this field also had the history in year surplus in the of ten, from used heat insulating material, (EPS) is in the majority with expanded polystyrene, fixing means from insulation construction, have adopt to paste, sticking nail in conjunction with or follow closely admittedly, also have when placing of concrete heat insulating material is placed directly in and water fixed closing in the template.
China utility model patent CN2454440Y discloses a kind of outer EPS of subsides heat-preserving wall, used external thermal insulation system comprises leveling layer, polymer cement tack coat, EPS polyphenyl foam warming plate, the fleece of imbedding the polymer cement coating, polymer cement and decoration of exterior wall etc., it is light to have volume, advantages such as thermal and insulating performance is good, and easy construction, speed are fast, need not take the interior space.Chinese invention patent application CN1955388A discloses thermal insulation sound-proof system and the job practices thereof that a kind of exterior wall is used, its heat-insulation system is made of fixed bed, warming plate, glass fiber reinforced layer and the topping of wiping one's face successively, by the combination of polymer modification cementing agent, make it to constitute an independent integral body between every layer; Glass fiber reinforced layer is a sandwich structure, and the centre accompanies the galvanizing electrowelding net, and the two sides is the screen cloth of alkali-resistant glass fibre braiding, and this system can effectively avoid the dewfall in winter, and resisting wind press capacity is good.
In these heat-insulation systems, the EPS warming plate that adopts is the rectangular structure of thin type, adjacent warming plate is arranged side by side mutually, independently stick on the foundation wall, thus, formed the plate seam that is directly connected to foundation wall between plate and the plate, thereby produced following defective: the existence of (1) plate seam has caused the generation of cold and hot bridge, has influenced the effect of exterior-wall heat insulation; (2) because the phenomenon of expanding with heat and contract with cold causes the topping cracking easily, and water resistance descends, make further that cracking, perk appear in warming plate, problem such as come off, influenced the application life of exterior wall heat-preserving system.Though reported that in CN2454440Y the slit is added with pitch flax silk and sealing cement at the bottom of warming plate, strengthen its water resistance, but caused the increase of construction cost on the one hand, on the other hand, because exterior wall environment for use condition is relatively poor, along with the significantly decline of its waterproof effect of prolongation of time, be difficult to really prolong the life-span of exterior wall heat-preserving system.
Summary of the invention
The utility model purpose provides a kind of outer wall thermal insulation system, by the improvement of structure, solves the problem that is prone to cold and hot bridge and water proofing property difference in the prior art.
For achieving the above object; the technical solution adopted in the utility model is: a kind of outer wall thermal insulation system; be compounded with leveling layer, polymer cement tack coat, insulation flaggy and topping from the inside to the outside successively; described insulation flaggy is made of along the longitudinal and transverse two directions tiling plural piece warming plate; be provided with ledge structure around the described warming plate; one group of relative opposite side step protuberance is positioned at warming plate planar opposite side and thickness cooperates; constitute the tiling splicing construction that cooperates between adjacent warming plate thus, the protuberance width of step is between 10 millimeters to 30 millimeters.
Further technical scheme, the step protuberance of described warming plate upper edge is positioned at next-door neighbour's outer surface of wall one side, the step protuberance of lower edge is positioned at away from outer surface of wall one side, in the upper and lower adjacent warming plate, the lower edge step of last warming plate is covered in down the outside of the upper edge step of warming plate.
In the technique scheme, described warming plate adopts the EPS plate, and its thickness is 30 millimeters to 50 millimeters.
In the technique scheme, described topping is by the topping of wiping one's face, grid cloth and the decoration of exterior wall layer is compound constitutes, and is bonding mutually between each layer.Wherein, described grid cloth can adopt alkali resistant glass fibre open weave cloth.
Optimized technical scheme, the bottom of described insulation flaggy and junction, ground are provided with L type angle iron bracket.
The job practices of outer wall thermal insulation described in the utility model system can adopt adhesive bonding method; But for obtaining better fixed effect, preferred job practices is, adopt sticking nail mode with polymer adhesive that the one side of warming plate is sticking on the wall on the basis of leveling layer, another side at warming plate is squeezed into crab-bolt, sequence of construction is from bottom to top adopted in the splicing of warming plate, aperture can appear in the lap-joint of corner plate and plate in the corner etc., and available polyurethane foam glue is stifled real.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
1,, make that dislocation is overlapping between adjacent warming plate, thereby seam has prolonged the plate face to the route that is communicated with between the foundation wall, has good water proofing property and sealing owing to being provided with ledge structure around the warming plate of the present utility model; Simultaneously, also solve in the conventional plate way problem that directly connects a large amount of cold and hot bridges that produce owing to plate face slit and foundation wall, improved the application life and the heat insulation effect of foundation wall greatly.
2, because overlapped interlock between warming plate of the present utility model relies on mutually, the warming plate in the foundation wall outside is joined together, form an integral body, thus stressed jointly, solved because the crack problem that discontinuity produces; Strengthen bonding force simultaneously, improved warming plate and whole fixing and the planarization that combines of foundation wall, had excellent waterproofness and heat-insulating property.
3, in the upper and lower adjacent warming plate of the utility model, the lower edge step of last warming plate is covered in down this structure of the outside of the upper edge step of warming plate, make the insulation flaggy form the discharge structure that covers from top to bottom, guaranteed that water is difficult for entering between the slave plate seam, further strengthened the water proofing property of heat-insulation system.
