Abstract
The utility model provides an external wall pre-manufactured wall panel, comprising an inner layer of the wall panel and an outer layer of the wall panel, wherein a heat preservation layer is arranged between the inner and outer layers of the wall panel; the outer layer of the wall panel is made of a reinforced concrete panel or a pre-painted color steel sheet steel plate construction, while the inner layer of the wall panel is made of a reinforced concrete panel. The utility model is characterized in that: bridge-cut-off reinforcing steel bars are arranged on the edges of the inner and outer layers of the wall panel, two external wall pre-manufactured wall panels, when connected, form a cavity in which molt filter is filled to connect the heat preservation layers of the pre-manufactured wall panels into an integral structure. As the utility model adopts reinforcing steel bars subject to bright-cut-off treatment on the inner and outer layers of the pre-manufactured wall panel and the molt filter filled into the cavity formed when the two pre-manufactured wall panels are connected to connect the heat preservation layers into an integral structure, the heat bridges can be prevented form happening greatly and the heat preservation performance is improved. The utility model has simple manufacture process, fast construction and heat preservation, hence an upgrade product of external wall pre-manufactured wall panel.
Description
Technical field:
The utility model relates to a kind of assembled architecture prefabricated units of building engineering field, particularly a kind of pre-fabricated panel that is used for skin.
Background technology:
The exterior wall wallboard of general assembled architecture, mainly form by the wallboard skin of band decorative cover, wallboard internal layer that band whitewashes with by the middle insulation layer of heat insulating effect, because middle heat insulating material is mostly softer frangible, generally all four limits and the door and window hole place of inside and outside structural meterials at wallboard fused, with heat preserving and insulating material all directions all comprehensively the parcel and do not expose, make various tongue and groove shapes again at the edge of wallboard, after installation, form integral body in the hope of wallboard, and play exterior wall enclosure structure functions such as preventing rain penetration.But such make forms cold and hot passage one heat bridge easily, and heat bridge claimed cold bridge again in the past, and existing unified naming is heat bridge.Be that the intensive passage of formation hot-fluid is heat bridge because the thermal transmittance at positions such as window lintel, collar tie beam, steel concrete antidetonation post, reinforced concrete shear wall, beam, post is much larger than the thermal transmittance of main body of wall in the space enclosing structure.Because heat bridge position internal surface temperature is lower, during severe winter, when this place's temperature was lower than dewpoint temperature, steam will condense in wherein, formed dewfall.After this, the body of wall water content strengthens and effect of heat insulation is poorer, blackening gradually, thus long bacterium is mouldy, even can drop down water, very big to life and health effect.Along with the raising that China requires building energy-saving, so in recent years, owing to be difficult to solve the heat bridge problem, the structure way of existing wallboard has been difficult to adapt to requirement, and the wallboard building has almost withdrawed from construction market.
Summary of the invention:
The utility model provides a kind of exterior wall pre-fabricated panel, can prevent effectively that heat bridge from producing heat preservation energy-saving.
The utility model primary structure is a three layer construction, the wallboard internal layer, the wallboard skin, in the middle of the wallboard ectonexine is insulation layer, the wallboard skin is armored concrete slab or steel plate structure, steel plate is generally selected color steel sheet for use, the wallboard internal layer is an armored concrete slab, between the layer inside and outside the wallboard, connect with a small amount of fine steel rib, fine steel rib is preferably selected zinc-plated fine steel rib (about φ 4mm) for use, the marginal portion of wallboard ectonexine uses the bridge cut-off reinforcing bar (between the reinforcing bar φ 10-14, be preferably in φ 12mm) fix inside and outside wallboard, to keep the globality of pre-fabricated panel, the bridge cut-off reinforcing bar is that reinforcing bar is disconnected when passing insulation layer, connect into whole reinforcing bar with heat-barrier material again, heat-barrier material can be selected nylon or glass-reinforced plastic material, as selects the nylon or the glass fiber reinforced plastic of tubulose for use, heat-barrier material is enclosed within the two ends that reinforcing bar disconnects securely, and the cavity of tube core also can be filled mineral wool heat-barrier materials such as (as glass wools).
Moistureproof vapour barrier is set between pre-fabricated panel internal layer and insulation layer; The edge of edge insulating layer and wallboard ectonexine is not on same plane, and such two pre-fabricated panel can form cavity when connecting, and injects polyurathamc as heat insulating material in cavity, makes the insulation layer between pre-fabricated panel connect into overall structure.
Lower limb on horizontal pre-fabricated panel outer wall flaggy is provided with tenon; Preferred oblate steel tenon; Wallboard skin between vertical everywhere and horizontal pre-fabricated panel seam, all side leaves connector within it, and connector is that the general connector that adopts gets final product in the existing technology, as the steel plate piece of burn-oning in the outer inboard of wallboard, it is as connector, whole with forming after the steel plate block welding.
Heat insulating material is provided with by the thermal insulation requirement, generally selects polyphenyl plate, extruded sheet or polyurethane etc. for use, requires to select for use the insulation layer material according to insulation.The edge of heat insulating material can be with the plastic sheeting parcel to prevent that heat insulating material is damaged and to prevent the aqueous vapor infiltration.
When pre-fabricated panel is installed, earlier the outer field reservation steel plate of wallboard is welded in the inboard, again the bridge cut-off bar reinforcement of reserving is joined together, then can be with cement fibrolite plate or gauze wire cloth polishing breach at the vacancy position of wallboard internal layer, outside cement fibrolite plate or steel wire, lay vapour barrier, inject polyurathamc in the cavity of vapour barrier and exterior panel on insulation layer, isolation layer is unified, polishing wallboard internal layer lacks the position again.
The utility model is because the reinforcing bar after having used the bridge cut-off processing between the pre-fabricated panel ectonexine, significantly reduced the generation of heat bridge, and inject polyurathamc in the cavity when connecting between pre-fabricated panel, make insulation layer connect into overall structure, further weaken heat bridge and produce, and improved heat-insulating property.
