A kind of is the external thermal insulation system structure of protected decoration layer with the polymer mortar
Technical field:
It is the external thermal insulation system of protected decoration layer with the polymer mortar that the utility model relates to a kind of, this system adopts polymer mortar to the protection of insulation layer, this polymer mortar layer has decoration functions simultaneously except having protective action, no longer need the veneer coating layer.
Background technology:
It is insulation layer that present building exterior wall heat preserving system adopts expansion polyphenyl plate or extruded polystyrene board, use polymer-modified cement-based bonding adhesive that insulation layer is pasted on wall face, insulation layer surface adopts polymer-modified cement-based finishing mucilage as the cracking resistance overcoat, the cracking resistance overcoat surface coating ornamental surface layer of must constructing again.Because the flexibility of polymer-modified cement-based cracking resistance overcoat is poor, usually cause external thermal insulation system cracking, infiltration phenomenon to occur.Simultaneously, because construction cracking resistance overcoat and finish coat belong to the operation of different work posts, construction is complicated, and is long in time limit, the expenses of labour height.
The utility model content:
In order to overcome present shortcoming and to solve the problem that exists, the utility model provides a kind of new external thermal insulation system structure.This system adopts the flexible polymer mortar and the chromogen bonded polymer decoration mortar that can have decoration functions and protective effect is provided simultaneously; composite glass fiber grid cloth in the polymeric trim screed; like this decoration overcoat of Xing Chenging have that anticracking, anti-water ooze, protection and decoration functions, the surface does not need supporting decorative paint surface layer again.
The beneficial effects of the utility model are: because polymer mortar layer is flexible good, make the novel external wall outer heat preservation system can effectively solve expansion polyphenyl plate, the cracking of thinly plastered external wall of extruded polystyrene board outer heat preservation system, seepage problem; Because polymer mortar layer has decoration functions, need not be coated with the construction exterior wall coating material again on the overcoat surface, reduce cost; Because the protected decoration layer only needs a work post construction, simplifies working process, and reduces operating expenses.
Below in conjunction with drawings and Examples the utility model is further specified.
Description of drawings:
Accompanying drawing is layer of structure figure of the present utility model.
In the accompanying drawings: 1. being basic unit's body of wall, can be masonry structure, also can be the structure wall of concrete pouring body of wall or other types; 2. be the bonding adhesive of pasting fixed expansion polyphenyl plate or extruded polystyrene board; 3. be expansion polyphenyl plate or extruded polystyrene board insulation layer; 4. be the crab-bolt that plays the mechanical assistance interconnect function; 5. be flexible general polymer screed; 6. be the fiberglass gridding cloth of humidification; 7. be chromogen bonded polymer decoration mortar surface layer.
2.~7. constitute with the polymer mortar is the external thermal insulation system of protected decoration layer.
Below the utility model is described in further detail by the specific embodiment.
The specific embodiment, non-limiting examples is as described below:
Embodiment 1
The external thermal insulation system structure insulation layer that with the polymer mortar is the protected decoration layer is an expansion polyphenyl plate, adopts that polymer-modified cement-based bonding adhesive is pasted, auxiliary crab-bolt mechanical connection is fixed in the exterior wall external surface; The insulation layer surface of system is the thick flexible general polymer screed of one deck 1mm~2mm, and fiberglass gridding cloth is applied in shop, screed surface, then is the thick chromogen bonded polymer decoration mortar layer of one deck 1mm~2mm.That is, system construction is: the thick flexible general polymer screed → fiberglass gridding cloth of the basic unit's body of wall → expansion polyphenyl plate heat preserving layer → 1mm~2mm → thick chromogen bonded polymer decoration mortar of 1mm~2mm layer.
Embodiment 2
The external thermal insulation system structure insulation layer that with the polymer mortar is the protected decoration layer is an extruded polystyrene board, adopts that polymer-modified cement-based bonding adhesive is pasted, auxiliary crab-bolt mechanical connection is fixed in the exterior wall external surface; The insulation layer surface of system is the thick flexible general polymer screed of one deck 1mm~2mm, and fiberglass gridding cloth is applied in shop, screed surface, then is the thick chromogen bonded polymer decoration mortar layer of one deck 1mm~2mm.That is, system construction is: the thick flexible general polymer screed → fiberglass gridding cloth of the basic unit's body of wall → extruded polystyrene board insulation layer → 1mm~2mm → thick chromogen bonded polymer decoration mortar of 1mm~2mm layer.
