The built on stilts floor of insulation
Technical field
The utility model relates to a kind of insulation construction of building, especially relates to the built on stilts floor of a kind of insulation.
Background technology
Complete insulation construction, can reduce the energy consumption of building.In existing multi-storey building or common private residence, built on stilts floor mainly comprises that the Roofing slab tiling by the unsettled setting of polylith forms or the cast-in-place floor basic unit forming of ordinary concrete, and the thermal transmittance of this built on stilts floor is very high, need to transform.Due to the unsettled setting of built on stilts floor, so insulation layer need to be arranged on floor basic unit bottom.In prior art, the inorganic light-weight aggregate thermal insulation mortar (I type) adopting is coated in floor basic unit bottom as heat insulating material, when smearing outward, the Coefficient K of the thick inorganic light-weight aggregate thermal insulation mortar of 30mm (I type) Shi, floor basic unit and insulation layer integral body is higher, is generally 1.65W/(m
2k), still surpass norm of construction 0.7~1.5W/(m
2k) requirement; And thicken again inorganic light-weight aggregate thermal insulation mortar (I type), and may cause that insulation layer is cracked to drop, safety can not guarantee.
Utility model content
It is lower that technical problem to be solved in the utility model is to provide a kind of heat transfer, insulation construction thinner thickness, the built on stilts floor of not easily broken insulation of dropping.
The utility model solves the problems of the technologies described above adopted technical scheme: floor is maked somebody a mere figurehead in a kind of insulation, it comprises floor basic unit, below described floor basic unit, be fixed with insulation layer, horizontally-spliced the forming of vacuum heat-insulating plate that described insulation layer is mainly all brushed interfacial agents by the upper and lower plate face of polylith, described insulation layer soffit is wiped with crack-resistant layer, and described crack-resistant layer soffit is wiped with water proof decorative surface layer.
As preferably, between described floor basic unit and insulation layer, be provided with cement mortar screeding layer, the vacuum heat-insulating plate of described formation insulation layer and cement mortar screeding layer are fixed by adhesive bonds.
Compared with prior art, the utility model has the advantage of that in the smooth rear setting of floor basic unit soffit, by the insulation construction consisting of the horizontally-spliced insulation layer forming of polylith vacuum heat-insulating plate, crack-resistant layer and water proof decorative surface layer, the Coefficient K of floor basic unit and insulation construction integral body is lower is 0.65 W/(m
2k) ~ 0.70W/(m
2k), meet norm of construction requirement, there is higher cracking resistance, water resistance simultaneously; The general thickness of insulation construction is 20mm ~ 22mm, not easily broken coming off, and safety is good.
As preferably, on described vacuum heat-insulating plate, be provided with reserved anchor hole, in described anchor hole, be provided with for the fixing anchoring piece of vacuum heat-insulating plate and floor basic unit.Make to be connected between vacuum heat-insulating plate and built on stilts floor more firm, prevent that vacuum heat-insulating plate from coming off.
As preferably, described crack-resistant layer is comprised of two-layer anticracking grout and middle alkaline-resisting grid cloth thereof.Cracking resistance is good, strengthens application life.
As preferably, described water proof decorative surface layer is followed successively by flexible putty layer, elastic bottom coating layer and elastic surface layer dope layer from top to bottom.Water resistance is good, strengthens application life.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
This preferred embodiment is illustrated in figure 1 the built on stilts floor of a kind of insulation, and it comprises is mainly tiled and formed or the cast-in-place floor basic unit 1 forming of ordinary concrete by polylith Roofing slab, and floor basic unit 1 smears cement mortar screeding layer 2 below; Also comprise that vacuum heat-insulating plate 3 horizontal cross of all brushing interfacial agents by the upper and lower plate face of polylith lay the insulation layer form, vacuum heat-insulating plate 3 is fixing by bonding adhesive and cement mortar screeding layer 2 bonding, below insulation layer, be wiped with crack-resistant layer 4, crack-resistant layer 4 is wiped with water proof decorative surface layer 5 below.The general thickness of the insulation construction being comprised of insulation layer, crack-resistant layer 4 and water proof decorative surface layer 5 is 20mm ~ 22mm, and the Coefficient K of insulation construction and floor basic unit 1 integral body is lower is 0.65 W/(m
2k) ~ 0.70W/(m
2k), meet norm of construction requirement.Wherein, levelling can be filled by thermal insulation mortar by the lap-joint of vacuum heat-insulating plate 3.
In addition, crack-resistant layer 4 is comprised of two-layer anticracking grout and middle alkaline-resisting grid cloth, and thickness should not surpass 6mm.Water proof decorative surface layer 5 is followed successively by flexible putty layer, elastic bottom coating layer and elastic surface layer dope layer from top to bottom, and thickness should not surpass 3mm.
In the present embodiment, vacuum heat-insulating plate 3 is the STP vacuum heat-insulating plate of the 10mm of Kunshan Lan Sheng building materials Co., Ltd production; On vacuum heat-insulating plate 3, be provided with reserved anchor hole 31, in anchor hole 31, can be provided for the fixedly anchoring piece 6 of vacuum heat-insulating plate 3 and floor basic unit, the general employing plastic expanding of anchoring piece 6 bolt.Vacuum heat-insulating plate 3 flattens inspection with the guiding ruler that length is not less than 2m when horizontal cross is laid, and uneven vacuum heat-insulating plate 3 need to be laid again.Vacuum heat-insulating plate 3 also can adopt the ultra-thin thermal insulation slab of DS-STP of the 10mm that the Zhejiang great Sen building energy conservation Science and Technology Ltd. of reserved anchor hole 31 does not produce.Anticracking grout adopts conventional formulation to make; Interfacial agents is the general synthetic basal plane inorganic agent of polymer modification liquid or the interfacial agents ANT-186 being supplied by Ningbo City Yin Zhou Xia Yingante Building Materials Factory; From Ningbo, integrated plasticizing Industrial Co., Ltd. buys alkaline-resisting grid cloth; It is 14501 that bonding adhesive is supplied its model by Ningbo City Yin Zhou Xia Yingante Building Materials Factory; Flexible putty is the cement based clay that the water-fast flexible putty ANT-621 of interior wall of Ningbo City Yin Zhou Xia Yingante Building Materials Factory supply is a kind of particular polymer modification; Elastic surface layer coating and elastic bottom coating are respectively internal wall elastic emulsion paint and the interior wall latex primer that Ningbo model's coating Co., Ltd supplies with.
