A kind of waterproof thermal-insulated anti-cracking wall body structure
Technical field
The utility model relates to building structure field, specifically refers to a kind of waterproof thermal-insulated anti-cracking wall body structure.
Background technology
In recent years, the concept of building energy conservation has goed deep into the association area of building trade, the fixed form that many employings are certain in external wall construction of exterior insulation system, good for heat insulating effect thermal insulation material is fixed on building masonry wall, increase the evenly heat resistance of body of wall, thus reach insulation or effect of heat insulation.But no matter be use organic insulation material if polystyrene, phenolic board or inorganic heat insulation material are as rock cotton board, mineral wool board, when installing as wall heat insulation material because insulating plate structure is not one, mortar joint is left between warming plate, easy generation skin coat cracking phenomena, the appearance in crack except the whole building of impact attractive in appearance except, skin coat water resistance also can be caused to lose efficacy, and after moisture infiltrates, the heat insulation effect of heat insulating material can degradation.
Utility model content
In order to solve the defect that existing technology exists, the utility model provides one and has excellent heat-insulating property, bonds evenly firm, and construction simply has the waterproof thermal-insulated anti-cracking wall body structure of one of fire protection flame retarding, resistance to compression waterproof, energy-conserving and environment-protective.
The technical solution of the utility model is to provide a kind of waterproof thermal-insulated anti-cracking wall body structure, comprises basic unit's exterior wall and anchoring piece, characterized by further comprising boundary mortar layer, polyurethane insulation coating, waterproofing course, anticracking grout layer, galvanized steel wire netting and decorative layer; Be provided with anticracking grout layer successively, waterproofing course between described galvanized steel wire netting side and basic unit's exterior wall, polyurethane insulation coating and boundary mortar layer, the opposite side of galvanized steel wire netting is decorative layer.
Further, described anchoring piece is the cross goods of stainless steel, and anchoring piece front end is embedded in basic unit's exterior wall, and it is successively through boundary mortar layer, and polyurethane insulation coating and waterproofing course, anchoring piece rear end is fixed between anticracking grout layer and galvanized steel wire netting.
Further, the width of described zinc-coated wire network plane overlap joint is 100mm.
Further, described galvanized steel wire netting is string diameter >=0.9mm, and mesh size is the zinc-coated wire sheet of 20mm × 20mm, and described polyurethane insulation coating is hard polyurethane foam warming plate.。
The utility model compared with prior art has obvious advantage and effect:
The utility model is provided with waterproofing course and galvanized steel wire netting on insulation layer, galvanized steel wire netting and cement anticracking grout define makes a concerted effort, add the tensile strength of horizontal direction and vertical direction, thus improve the intensity of decorative layer veneer basic unit, and then effectively prevent outer wall cracking and seepage problem; Be a kind of from heavy and light, cheap, heat-proof quality is good, fireproof heat insulating, the waterproof thermal-insulated exterior wall that compressive strength is good.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated:
The technical solution of the utility model is to provide a kind of waterproof thermal-insulated anti-cracking wall body structure, comprises basic unit's exterior wall 1 and anchoring piece 8, also comprises boundary mortar layer 2, polyurethane insulation coating 3, waterproofing course 4, anticracking grout layer 5, galvanized steel wire netting 6 and decorative layer 7; Be provided with anticracking grout layer 5 successively between described galvanized steel wire netting 6 side and basic unit's exterior wall 1, waterproofing course 4, polyurethane insulation coating 3 and boundary mortar layer 2, the opposite side of galvanized steel wire netting 6 is decorative layer.
Further, described anchoring piece 8 is the cross goods of stainless steel, and anchoring piece 8 front end is embedded in basic unit's exterior wall 1, and it is successively through boundary mortar layer 2, polyurethane insulation coating 3 and waterproofing course 4, anchoring piece 8 rear end is fixed between anticracking grout layer 5 and galvanized steel wire netting 6; Described polyurethane insulation coating 3 is hard polyurethane foam warming plate.Described galvanized steel wire netting 6 is string diameter >=0.9mm, and mesh size is the zinc-coated wire sheet of 20mm × 20mm; The width of the plane overlap joint of galvanized steel wire netting 6 is 100mm; Galvanized steel wire netting 6 anchoring piece 8 is fixed, the spacing≤300mm between anchoring piece 8.Galvanized steel wire netting 6 after fixing require smooth, firm, there is no warping phenomenon, do not affect the construction of decorative layer.Galvanized steel wire netting is set up outside anticracking grout, hot-galvanized steel silk screen and cement anticracking grout are defined make a concerted effort, add the tensile strength of horizontal direction and vertical direction, thus improve the intensity of decorative layer veneer basic unit, and then effectively prevent outer wall cracking and seepage problem.
