Description
Technical field
The utility model relates to assembled architecture field more particularly to a kind of thermal-insulation connecting pieces.
Background technique
Three kinds of modes of current China's external wall body thermal insulation according to the position different demarcation in wall be inside holding, external thermal insulation and
Sandwich heat preservation.Since the fire resistance of external thermal insulation is poor, the less indoor usable floor area of inside holding and is easy the disadvantages of mouldy, limit
The popularization and use of both heat preserving modes are made.Sandwich heat preserving wall body not only have it is heavy, go along with sb. to guard him and heat insulation function, and can rise
To fire prevention and anti-corruption effect, thus, sandwich heat preserving wall body assembled architecture field apply it is relatively broad.Prefabricated sandwich heat preservation
Overlapped shear wall ten connects integral wall by thermal-insulation connecting piece with insulating layer by inside and outside impeller.Thermal-insulation connecting piece passes through certainly
The connecting structure of body links into an integrated entity outer impeller, interior impeller, insulating layer three, to the performance of prefabricated sandwich heat preserving wall body and
The critically important effect of start-stop is improved usually to adopt since thermal-insulation connecting piece part need to have low thermal conductivity and preferable mechanical property
With stainless steel or fibre reinforced composites.
As shown in Figure 1, existing sandwich heat preservation overlapped shear wall includes in opposite prefabricated interior 9 He of impeller disposed in parallel
Prefabricated outer impeller 12 is equipped with internal lobe plate reinforced mesh in prefabricated interior impeller 9, and siphonal lobe plate steel mesh is equipped in prefabricated outer impeller
Piece 16, the gap (i.e. after-pouring cavity 10) between prefabricated interior impeller 9 and prefabricated outer impeller 10 are equipped with truss bars 15 in
Between reinforced mesh 11, the two sides of truss bars 15 are connected with internal lobe plate reinforced mesh 17 and intermediate reinforced mesh 11 respectively.Wherein,
Girder rib (steel bar girder) plays a part of several aspects, and first is that (internal lobe plate reinforced mesh is in for two layers of reinforced mesh of connection
Between reinforced mesh), guarantee that two layers of reinforced mesh has a reliable connection, second is to guarantee certain rigidity, when rear pouring concrete, is
Guarantee that the reinforcing bar of the inside is not distorted when pouring or other deformations, truss bars have certain rigidity and guarantee that mesh sheet is hung down
Directly.Third, in terms of stress, truss bars play the role of tension rib.4th guarantee new-old concrete preferably connects, unlikely
In the failure by shear that new-old concrete joint surface occurs in the case where high axial compression ratio.Existing thermal-insulation connecting piece uses stainless steel
The either mode that FRP composite material or stainless steel are combined with resin material, effect mainly connect inside and outside impeller and are formed
It is whole, and form bridge cut-off.At present using FRP stick in sandwich heat preservation overlapped shear wall, technique, simple structure, but due to it
The limitation of inside and outside impeller thickness, anchoring ability is relatively poor, causes unit area usage quantity more, high expensive.Have
Sandwich heat preservation overlapped shear wall is integral by the connection of inside and outside impeller across insulating layer using truss bars, has cold-heat bridge to have larger
Influence.Meanwhile truss bars connect inside and outside leaf wallboard, in plant produced, since truss truss bars are in longitudinal direction
Continuity causes difficulty to the placement of reinforced mesh in in-situ layer (hollow space), increases production difficulty.
