Description
Technical field
This utility model belongs to external wall technical field, particularly relate to a kind of the most cast-in-place with concrete build prefabricated exempt to dismantle whole
The external wall system of body assembling insulation exterior sheathing.
Background technology
The compulsory execution of building energy-saving standard and city management are to building waste and the strict management and control of construction noise.
Traditional shear wall construction is after reinforcing bar has been pricked, outside workman installs on the landing stage of scaffold and floor respectively,
Interior masterplate and support system, inner and outer template in inner support (being typically fixed on steel reinforcement cage with wall thickness equal length reinforcing bar) and
Split bolt or to drawing under the common effect of band iron, forms concrete placings cavity, after concrete reaches strength of mould stripping, removes masterplate
And support.
At present, in order to reach power conservation requirement, newly-built concrete shear wall external wall is both needed to the structure of heat-insulation layer, existing
The scheme of the problem that technology solves insulation mainly has two kinds, and one is to be placed in exterior sheathing with the adiabator plate with steel wire
Side, is combined with concrete wall by plugging wire during concrete placings, after form removal, plasters, makees decoration of exterior wall；Two is concrete main body
First construct, after paste warming plate, after screening, nailing are reinforced, make wall decoration.These two kinds of schemes are both needed to again take
Scaffold or suspension bracket, plaster, the wet trade such as coating, there is high-altitude application and disaster hidden-trouble, the most once protected
