The single-chamber heat-preserving wall component of degree.
The object of the present invention is achieved like this：
Including warming plate, the warming plate is made up of the grafting of unit module tongue and groove or rabbet overlap joint, in addition to outer protective plate, interior
Layer protective plate, light steel truss and bolt, light steel truss are arranged on the inner side of warming plate, and outer protective plate is arranged on warming plate
Outside, outer protective plate and warming plate be connected by bolt through outer protective plate and warming plate with light steel truss, internal layer
Protective plate is arranged on light steel truss, and external cavity is formed between warming plate and internal layer protective plate.
The present invention can also include：
1st, in addition to framework of steel reinforcement, the light steel truss is connected with framework of steel reinforcement.
2nd, the upper of warming plate is tongue and groove below, and left and right side is rabbet.
3rd, the outer surface of the size of outer protective plate and warming plate is equal sized, the left side retraction insulation of outer protective plate
The right of warming plate is stretched out on the left side of plate, the right of outer protective plate.
4th, described bolt includes screw rod, and the rear end of screw rod carries spacer, and there are screw thread and nut in the front end of screw rod.
5th, decorative panel can also be included, decorative panel is fixed on outer protective plate by anchor studs.
The present invention sets outer protective plate and internal layer protective plate in the both sides of warming plate respectively, and outer protective plate and internal layer are anti-
Backplate is connected by light steel truss with warming plate, and forms a cavity in the inner side of warming plate.The present invention is by being incubated
The connection composition single-chamber heat-preserving wall component such as plate, outer protective plate and internal layer protective plate, by the major part of building wall body construction
Process is completed by batch production, and scene only needs to lay reinforcing bar, casting concrete composition supporting course in the cavities, you can needed for being formed
The interior outside wanted all carries the energy-saving heat-insulating wall of overcoat.
The present invention warming plate as building masonry wall heat-insulation layer.Outer protective plate and internal layer protective plate are in wall construction
During as concreting template, after the completion of pouring again be wall interior external protection coating.Supporting course, heat-insulation layer, interior wall
Face and wall face one-shot forming.
The present invention not only can accelerate the construction speed of building, construction period shortens, and also advantageously improves wall
The quality of body, reduces cost.
The present invention is a kind of assembled single-chamber insulation and structure-integrated cavity wall non-dismantling formwork system.In operating platform
On, horizontal reinforcement is connected with light steel truss structure, vertical reinforcement and horizontal reinforcement connect and compose steel skeleton；Inner side non-dismantling formwork is used
Connected nail is fixed on the inside of steel skeleton, and connected nail penetrates steel skeleton and is exposed in cavity；After steel skeleton is stood up, then by warming plate and outside
Side protective plate is fixed by bolts to the outside of steel skeleton, and bolt penetrates steel skeleton and is exposed in cavity；Decorative panel is connected again
Nail（Or bonding method）It is fixed on the outside of protective plate, constitutes the assembled single-chamber insulation for having finish coat and structure-integrated cavity wall
Body non-dismantling formwork system.
By the system by lifting it is in place after, the casting concrete in cavity, as skin body.This method makes to apply
Work degree of progress speed, construction period shorten, it is ensured that quality, reduce cost.
