The hollow structure of outer insulation construction of the present utility model for not running through mutually at many levels, can slow down vibroseis and clash into sound wave transmission, sound absorption reduction; Outer insulation construction does not contain harmful ingredients, and during burning, can not produce pernicious gas, nontoxic, tasteless, "dead", non-corrosiveness, and environmental protection, reduces environment pollution.
Fire-protection rating of the present utility model is A level, and the scope of application is unrestricted, is the outer insulation construction that higher grade.
Insulation layer of the present utility model is smeared for manual, constructs convenient, reduces construction sequence, and lower to constructor's requirement, cost is lower, can be widely used in the heat preservation construction of external wall, interior wall, roofing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1-reinforced concrete beam, 2-exterior wall, 3-steel concrete windowsill bear down on one, 4-boundary mortar layer, 5-RFT self-controlled phase-variable energy-storage economical layer, 6-polymers anti-cracking mortar layer, 7-alkali resistant glass fibre open weave cloth, 8-surface layer.
The specific embodiment
Embodiment is shown in Figure 1, a kind of RFT self-controlled phase-variable energy-storage economical external heat preserving structure for exterior wall, be included in boundary mortar layer 4, insulation layer, crack-resistant layer and surface layer 8 that the sidewall of exterior wall 2 is provided with from the inside to the outside successively, described insulation layer is RFT self-controlled phase-variable energy-storage economical layer 5.
The thickness of described RFT self-controlled phase-variable energy-storage economical layer 5 is at least 50mm.Described crack-resistant layer is the polymers anti-cracking mortar layer 6 of compound alkali resistant glass fibre open weave cloth 7, and the thickness of crack-resistant layer is 3mm～5mm.The thickness of described boundary mortar layer 4 is 3mm～5mm.
Described surface layer 8 is adornd the flexible putty layer of expecting for outside scribbles.
In the present embodiment, the construction sequence of RFT self-controlled phase-variable energy-storage economical external heat preserving structure for exterior wall is as follows:
Step 1, the control of planeness, verticality: if the error of the planeness of exterior wall, verticality is greater than 10mm, need to use cement mortar to carry out levelling, stay hair side; If the planeness of exterior wall, the error of perpendicularity are greater than 20mm, must process by national relevant specification, guarantee not hollowing cracking of cement mortar screeding layer.
With transit, the vertical control line of exterior wall is emitted, control exterior wall verticality, with level gauge, the transverse horizontal control line of outer surface of wall is emitted, control horizontal planeness.
Step 2, paste ash cake, floating screed: according to the design thickness of RFT self-controlled phase-variable energy-storage economical layer, in the top of body of wall fixed vertical, control logical line, and lead to according to vertical control the ash cake that line is done vertical direction, again according to the logical line between two vertical direction ash cakes, do the thickness ash cake of metope insulation layer, the distance between every two ash cakes is no more than 2m.Ash cake can be with using the material identical with RFT self-controlled phase-variable energy-storage economical layer to make.
Step 3, base treatment: in the present embodiment, exterior wall 2 is the BM chained block infilled wall that 200mm is thick, and the surperficial floating dust of infilled wall is cleaned out, and sprinkles water moistening; The steel concrete windowsill that processing is positioned at the upper and lower both sides of building block infilled wall bears down on one 3 and the outer surface of reinforced concrete beam 1, (comprise the concrete constructional column, lintel of infilled wall and with the surface after cement mortar bottoming).
The boundary mortar layer that 3～5mm is thick is smeared on the surface of step 4, concrete structure and building block, forbids to omit, and guarantees and insulation first pass bonding.
RFT self-controlled phase-variable energy-storage economical layer is smeared in step 5, gradation:
First carry out spice, use flabellum mixer, by RFT self-controlled phase-variable energy-storage economical material: water=1:0.75(weight ratio) be stirred into paste, with mixing with use, heat preservation slurry was finished in 2 hours.
Then RFT self-controlled phase-variable energy-storage economical layer is smeared in gradation, and notes following item:
(1) each smearing thickness is not more than 2cm, and hair side is stayed on surface.
(2) after the formation initial set of smearing for the first time, smear second time, thickness is no more than 2cm, and hair side is stayed on surface.By that analogy, until design thickness, and levelling receipts light, after being dried, carry out next process construction.
(3) when gradation is smeared, answer appropriateness to press, to guarantee that layer and layer can be formed with effective adhesive, but can not smear back and forth pressure at same position.In smearing, if find that there is bulge, produce, should reject in time to mend and smear.
On RFT self-controlled phase-variable energy-storage economical layer, smear gradation and smear polymers anti-cracking mortar, primary THICKNESS CONTROL is at 1～2mm, then with trowel, alkali resistant glass fibre open weave cloth is pressed into primary polymers anti-cracking mortar, net is depressed in lap-joint's online, lap width must not be less than 50mm, is first pressed into a side, then smears the polymers anti-cracking mortar that width is 100mm, after be pressed into opposite side, forbid dry taking.Alkali resistant glass fibre open weave cloth paving is smooth, corrugationless, and plumpness reaches 100%.
Smear polymers anti-cracking mortar levelling alkali glass fiber reticular cloth for the second time.With trowel, the slurry of polymers anti-cracking mortar is pressed in net, requires alkali glass fiber reticular cloth and primary polymers anti-cracking mortar to glue in fact, tack coat is thin, and the gross thickness of polymers anti-cracking mortar layer is controlled at 3～5mm.
RFT self-controlled phase-variable energy-storage economical layer is commercially available novel heat insulation layer on market, the special tectonic of the brucite fiber of this novel heat insulation layer forms the globality that netted tension structure can guarantee insulation layer, in insulation layer, hydroxyl ion alkalescence forms non-physical height bonding with the free acid generation substitution reaction of metope surface simultaneously, guaranteeing has effective adhesive with body of wall, in addition insulation layer self has 5% cubical expansivity, has fundamentally overcome the generation of crack, crackle.
This insulation layer has hydrophobic function, can effectively avoid easing back and easily causing the disadvantage of body of wall disengagement after traditional insulation layer moisture absorption, and this insulation layer is one pack system, is watered in proportion condiment, and the quality of insulation layer easily guarantees.
