Abstract

The utility model relates to a thermal insulation structure of a construction external wall, which comprises a thermal insulation layer that is arranged on the surface of the external wall; the surface of the thermal insulation layer is provided with an anti-crack layer; a mesh-shaped steel wire layer is also arranged between the thermal insulation layer and the anti-crack layer; and the steel wire layer is connected to the external wall by an expansion bolt. As the utility model has the steel wire layer, the combination firm degree between the anti-crack layer and the thermal insulation layer is enhanced, thereby not only the anti-crack performance is improved, but also the overall strength and the loading capacity of the thermal insulation structure are greatly improved as the steel wire layer is also fixedly connected with the external wall, thus, taking the installation stone and the like as the decorative layer of the appearance is completely feasible. Moreover, the increase of the steel wire layer leads the construction of the thermal insulation layer of the external wall to be rapid and flexible, so not only one-time casting with large area can be carried out, but also the form of a precast thermal insulation board and the like can be adopted for installation; the efficiency thereof is high; the thermal insulation and energy conservation effect thereof is reliable; and the cost of the project is reduced.

Description

The building exterior wall heat preserving structure

Technical field:

The utility model relates to a kind of heat insulation structure of skin.

Background technology:

In order to make building more energy-conservation, all need to be provided with insulation construction on the exterior wall of many buildings now, prevent the heat transmission.Common insulation construction is that repeatedly manual being coated with spread polymer beads formation insulation layer on external wall, be coated with in insulation layer surface again and spread crack-resistant layer, but the insulation layer that this repeatedly cast-in-place construction forms is inhomogeneous, be easy to generate the crack, heat insulation effect is unreliable, crack-resistant layer and insulation layer also relatively poor in conjunction with firmness, and the efficiency of construction of integral insulation construction is low, increased the duration, the comprehensive cost height.And, many buildings can increase decorative layers such as stone material again on the crack-resistant layer surface, and the bulk strength of insulation construction and bearing capacity are very poor, are very easy to damaged in the decorative layer construction, can limit the decoration of exterior wall of building and select, the popularization of building heat preservation structure also is affected.

Summary of the invention:

At the deficiencies in the prior art, the utility model provides a kind of bulk strength height, the building exterior wall heat preserving structure rapidly of constructing.

The utility model comprises the insulation layer that is located at exterior wall surface, and insulation layer surface then is provided with crack-resistant layer, also be provided with netted steel wire floor between insulation layer and crack-resistant layer, and steel wire floor is fixedly connected on the exterior wall by expansion bolt.

In the structure of the present utility model steel wire floor is arranged, make improving between crack-resistant layer and the insulation layer in conjunction with firmness, not only improved cracking resistance, and steel wire floor is also fixedlyed connected with exterior wall, the bulk strength and the supporting capacity of insulation construction are improved greatly, even it is also feasible fully as the decorative layer of appearance that stone material etc. is installed.And, make the construction of exterior wall insulated structure flexible rapidly after increasing steel wire floor, can large tracts of land once cast-in-place, also can adopt form such as prefabricated thermal insulation plate to install, the efficient height, heat preservation and energy conservation effects is reliable, has reduced the cost of engineering.

Further specify the utility model below in conjunction with drawings and Examples.

Fig. 7 is the schematic cross-section of prefabricated thermal insulation plate overlap joint.

Embodiment 1: as depicted in figs. 1 and 2, insulation layer 1 is located at the surface of exterior wall 4, and insulation layer 1 surface then is provided with crack-resistant layer 2, also be provided with netted steel wire floor 3 between insulation layer 1 and crack-resistant layer 2, and steel wire floor 3 is fixedly connected on the exterior wall 4 by expansion bolt 5.Insulation layer 1 adopts polymer beads, generally is that granular polystyrene mixed glue solution slurry is made, and the thickness about three centimetres can be better heat insulation.The polyphenyl insulation layer 1 of present embodiment after testing, coefficient of thermal conductivity is 0.054w/m.k, less than the 0.06w/m.k of state's scale value, heat-insulating property is better.The gauze wire cloth of steel wire floor 3 general available 0.5 millimeter, crack-resistant layer 2 generally then can be smeared three millimeter and be got final product with glass or cloth fibre cement mortar.Crack-resistant layer 2 is the high-strength structure layer, and general material mixture ratio is glass or cloth fibre: cement: sand :=1: 100: 160, and water/binder ratio is 0.35, compressive strength 〉=40MPa, tensile strength 〉=3.5Mpa.

Present embodiment adopts field fabrication when construction, earlier the steel wire floor 3 of enough areas is fixedly connected on the exterior wall 4 every sky by cushion block and expansion bolt 5 are parallel, every Ullage from about three centimetres, the granular polystyrene slurry that mixes can be poured into space between steel wire floor 3 and the exterior wall 4 with air spraying or manual mode of smearing then, and fill up to solidify and form insulation layer 1.Smear glass or cloth fibre cement mortar formation crack-resistant layer 2 at steel wire floor 3 together with insulation layer 1 surface again, can finish insulation construction construction external wall 4.As required, 7 on general decoration of exterior wall layer is located at crack-resistant layer 2 appearances, can use stone material, coating etc.

Because insulation layer 1 can expand with heat and contract with cold, it is separate unit that the insulation construction that general insulation layer 1, steel wire floor 3 and crack-resistant layer 2 are formed all is no more than 20 meters with length, width, as shown in Figure 3, be provided with shrinkage joint 6 between each separate unit, and be filled with elastic filler in the shrinkage joint 6, polyurethane material is generally used in elastic filler, energy elastic telescopic, and waterproof sealing.

Embodiment 2: as shown in Figure 4 and Figure 5, insulation layer 1 also is provided with tack coat 8 together with the form of steel wire floor 3 composition prefabricated thermal insulation plates between insulation layer 1 and exterior wall 4.Because adopt the precast plate form, the uniformity and the quality of insulation layer 1 are more reliable.During construction, the prefabricated thermal insulation plate can be connected exterior wall 4 surfaces by adhesive linkage 8, be fixed with expansion bolt 5, installation rate is very fast.

The area that the prefabricated thermal insulation plate is every is little, as shown in Figure 6 and Figure 7, steel wire floor 3 edges on general each prefabricated thermal insulation plate surface overlap mutually by gauze wire cloth 9, insulation layer is then filled glue mud between 1 edge, and length, the width of the separate unit that each prefabricated thermal insulation plate overlap joint constitutes also all are no more than 20 meters, can form bigger area like this, and guarantee bulk strength.Also need shrinkage joint 6 between the separate unit that a plurality of prefabricated thermal insulation plates are overlapped to form, handle with embodiment 1.Equally, after forming crack-resistant layer 2, also can construct as required decorative layer 7 is set.
