Abstract
The utility model discloses a phenolic foam board external wall structure, which comprises a heat-insulation layer and a decorative surface layer which are arranged outside a wall body in sequence, and is characterized in that the heat-insulation layer is made of phenolic foam boards. The external wall structure is excellent in heat-insulation performance and fireproof performance, and has the advantages of simple structure, convenience for construction, low cost, long service life and the like at the same time.
Description
Technical field
The utility model relates to the decorating outer wall of building field, especially relates to a kind of phenolic board external wall structure.
Background technology
Along with the raising of people to building safety and energy-saving consumption consciousness, the general all requirements of modern high-rise building possess good heat preservation and insulation and good fireproof performance.In modern architecture, in order to reach heat preservation and insulation, generally adopt hollow constructional materials or add one deck heat-barrier material on exterior wall; In order to reach good fireproof performance, also need to set up again one deck fireproof material layer simultaneously.Caused complex structure, the defective that cost is higher.
The utility model content
For above-mentioned deficiency, technical problem to be solved in the utility model is how to provide a kind of heat preservation and insulation and fireproof performance good, phenolic board external wall structure simultaneously simple in structure, with low cost.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of phenolic board external wall structure comprises the thermal insulation separation thermosphere and the finish coat that are successively set on the body of wall outside, it is characterized in that, described thermal insulation separation thermosphere adopts phenolic foam board to make.
Phenol formaldehyde foam (Phenolic Foams) is described as " king of insulation ", and the phenol formaldehyde foam flat board that 25mm is thick stands the flame of 1700 ℃ and sprays after 10 minutes, and the surface is slightly carbonization and not burning through only, neither can catch fire, and does not also distribute dense smoke and poison gas.The phenol formaldehyde foam plate material is to be formed by thermosetting phenolic resin foaming, it have lightweight, fire prevention, chance naked light do not burn, smokeless, nontoxic, without drippage, do not shrink under wide (190 ~+200 ℃) environment of the scope of application, the advantage of not embrittlement.Because the phenol formaldehyde foam rate of closed hole is high, coefficient of thermal conductivity is low, heat-proof quality good, and has good water resistance, and chemical composition stability, and anti-corruption is anti-aging, is the green heat insulating material of desirable fire prevention, thermal insulation, energy-conservation, attractive in appearance, environmental protection.In the utility model, adopt phenolic foam board to form the thermal insulation separation thermosphere, can make exterior wall possess simultaneously good heat insulation effect and heat-insulating, fire-preventing effect, make it possess the advantages such as simple in structure, with low cost, easy construction.
As optimization, described exterior surface of wall also is provided with leveling layer, and the phenolic foam board of described thermal insulation separation thermosphere adopts bonding adhesive to stick on outside leveling layer.Like this, the leveling layer levelling is set first, then the thermal insulation separation thermosphere is set, the bonding that is beneficial to phenolic foam board is fixed.During concrete enforcement, leveling layer can adopt cement material to make.
As optimization, described finish coat is external coating or decorating surface brick layer.Make it specious, satisfy vision requirement.
As optimization, also be provided with the anti-cracking protective layer structure, the anti-cracking protective layer structure is between described thermal insulation separation thermosphere and finish coat, described anti-cracking protective layer structure comprises the anticracking grout layer, be folded with at least one layer of grid cloth or gauze wire cloth in the anticracking grout layer, also be provided with expansion anchor and inwardly pass successively anticracking grout layer, thermal insulation separation thermosphere and be fixed on body of wall along anticracking grout layer external surface.Described anti-cracking protective layer structure has adopted anticracking grout, simultaneously in the middle of anticracking grout sandwiched grid cloth or gauze wire cloth, can greatly improve outer-wall crack-resisting.The expansion anchor that arranges is simultaneously reinforced, and can make whole external wall structure and body of wall more securely connect as one, and avoids peeling off, and improves reliability and application life.
As further optimization, described grid cloth adopts alkali resistant glass fibre open weave cloth.Have cost low, intensity is good, is difficult for the advantages such as corrosion.
In sum, external wall structure of the present utility model, heat preservation and insulation and fireproof performance are good, possess simultaneously the advantages such as simple in structure, easy construction, with low cost, long service life.
Description of drawings
Fig. 1 is the utility model structural representation when specifically implementing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, as shown in Figure 1, a kind of phenolic board external wall structure comprises the thermal insulation separation thermosphere 2 and the finish coat 3 that are successively set on body of wall 1 outside, and wherein, described thermal insulation separation thermosphere 2 adopts phenolic foam board to make.Described body of wall 1 external surface also is provided with leveling layer 4, and the phenolic foam board of described thermal insulation separation thermosphere 2 adopts bonding adhesive to stick on outside leveling layer 4.Described finish coat 3 is external coating or decorating surface brick layer.Also be provided with the anti-cracking protective layer structure, the anti-cracking protective layer structure is between described thermal insulation separation thermosphere 2 and finish coat 3, described anti-cracking protective layer structure comprises anticracking grout layer 5, be folded with at least one layer of grid cloth or gauze wire cloth 6 in anticracking grout layer 5, also be provided with expansion anchor 7 and inwardly pass successively anticracking grout layer 5, thermal insulation separation thermosphere 2 and be fixed on body of wall 1 along anticracking grout layer external surface.Described grid cloth adopts alkali resistant glass fibre open weave cloth.
In the utility model, used phenolic foam board as the external wall structure insulation layer, phenolic foam board has good flame resistant performance and thermal stability, therefore make external wall structure possess good heat-insulating property and heat supply fireproof performance.
Phenolic-aldehyde heat-insulation board flame resistant performance mainly comprises two aspects, the one, prevent the ability of flame spread, i.e. and the local flame that produces of thermal insulation material, flame is with indiffusion and from horizontal blanking; The 2nd, the heat-insulating property of material itself, even at material one side ignition, the temperature of opposite side can not rise highlyer and cause that fire enlarges.Compared two characteristics with polystyrene, polyurethane foam: the one, when catching fire without the dropping phenomenon; The 2nd, the surface forms closely knit carbon-coating when catching fire, and this has just stoped the further burning of foam.
Heat stability, phenol formaldehyde foam have good heat stability in certain temperature range, its continuous serviceability temperature scope before contraction or cracking occurring is-190 ~ 200 ℃.Mix inert filler in the phenolic foam foaming component and can obviously improve heat stability, as the phenol formaldehyde foam that adds 10% glass fiber can stand 800 ℃ of high temperature and not occur in 1 hour shrinking and cracking, it uses also unrestricted at low temperatures, and these performances are that other organic foam can not reach.
