Technical field
The utility model is related to building heat preserving construction work technical field, especially, is related to a kind of non-dismantling formwork insulation
Decorative panel external wall protection body system and its construction method.
Background technology
Referring to Fig. 1(101 be shuttering supporting keel in figure, and 102 pour for foam cement, and 103 be template, and 104 be 6mm thick
Cement fibrolite plate, 105 be keel, and 106 be M5*25 self-tapping screw, and vertical spacing is 100mm), conventional peripheral revetment body
Way generally has following several situations:
Traditional method one:Be prefabricated in the factory PC components(Concrete sandwich wallboard), on-site hoisting, concrete panel uses steel
Corner brace processed is fixed with girder steel, carries out inside and outside Decorative Construction after the completion of lifting component again.The problem of existing:1. component is not held in itself
Weight, is conducted oneself with dignity too heavy as wallboard using concrete, brings burden to structure on the contrary, only can increase the section chi of girder steel and steel column
Very little, waste of resource increases cost.PC components are suspended vacantly using steel corner brace with girder steel, and corner brace uses spiral shell with wallboard from interior survey
Bolt is fixed, and corner brace is higher by the thickness of the whole corner brace of metope, is subsequently still needed to secondary levelling using cement mortar.2. wallboard fixed form
To be suspended vacantly PC components using steel corner brace, to avoid the PC structure manufacture deviations of plant produced excessive, in component and beam
The wide seams of 20mm are specially reserved between post, component and component as component deviation adjustment space, it is follow-up using cement mortar material envelope
Stifled, the wide seams of 20mm, which are dealt with improperly, is easily caused condensation, and leak, wall sound insulation has problem.
Traditional method two:Be prefabricated in the factory light cellular partition board(Cement and polystyrene particle, pearlite slab), on-site consolidation operation,
Inside and outside Decorative Construction is carried out after the completion of assembling construction.The problem of existing:Asked 1. precast light wallboard exists to be connected with girder steel
There is infiltration hidden danger in topic, edge joint position.2. there is cold bridge in girder steel position, the problem of there is condensation.
Traditional method three:Common grouting wall system, using double lightgage steel joist as wall skeleton, the interior outside of keel is adopted
Fixed with 6mm solid cement fiberboards, respectively as materials for wall, insulation material, dragon are used as using rock wool between row's keel outside
Bone is handled using the thick extruded sheet bridge cut-off of 20mm, inside and outside use template support, and centre pours lightweight slurry(Foam concrete or cement
Granular polystyrene), form removal, the inside and outside Decorative Construction of completion.The problem of existing:Since 1. employing 6mm solid cements fiberboard work
For interior external wall body, then support template and form removable operation, 6mm solid cement fiberboards do not work, waste of resource.2. template
Supporting is needed one entirety of whole metope formation, and every template wants the height of a flood, otherwise between template and template
Easily stagger during filled and process concrete or other lightweight slurries, cause wall uneven.This operational method difficulty is big,
And can not realize occur that wall is seriously uneven after form removable, the phenomenon of distortion, it is difficult to control gives follow-up finish coat construction band
Carry out serious disastrous effect.
