Description
Technical field
The present invention relates to technical field of buildings, especially a kind of exterior wall built through cast-in-place overlapping precast concrete plate and its construction
Method.
Background technology
With the popularization of building industrialization, PC assembled skyscrapers in all parts of the country start one after another, wherein being relatively difficult to resolve certainly
The problem of be precast shear wall component production and lifting.And composite plate shear wall system is as in Germany wide variety of one
Individual ripe structural system, can preferably solve the above problems.But the technology needs to use tipper, the early stage of this kind equipment
Input is high（The equipment is not sold singly, and the German production line containing the equipment needs 50,000,000 RMB or so, and is free of the equipment
Common home made production line price is no more than 10,000,000）, the maintenance cost during operation is all high.Such technique is first to make one
Prefabricated board of the piece with steel bar girder, after after the steam-cured end of the plate, is pressed into other one piece by tipper and keeps flat the steel just poured
Reinforced concrete prefabricated board, two pieces of prefabricated boards pressed together are steam-cured again.Manufacturing process is comparatively laborious, to plant equipment requirement
It is high.
Produced, transported to again after factory's progress is interim to spelling by the way that composite plate shear wall is decomposed into different prefabricated components
Job site, is a more economical method, but the external wall elevation of building has higher requirement on attractive in appearance, perpendicular soundness,
How the composite plate shear wall system for being decomposed into different prefabricated components is used for the external wall elevation of construction of buildings, is one and grinds
Study carefully direction.
The content of the invention
The present invention proposes a kind of exterior wall built through cast-in-place overlapping precast concrete plate and its construction method, can be overlapped into cast-in-place
The precast concrete plate of type is used to build external wall elevation, significantly reduces the production cost of precast concrete plate.
The present invention uses following technical scheme.
A kind of exterior wall built through cast-in-place overlapping precast concrete plate, the alien invasion of the exterior wall formation building body is described outer
Wall construction includes floor slab structure, prefabricated siphonal lobe wall and prefabricated internal lobe wall；The prefabricated siphonal lobe wall, prefabricated internal lobe wall have one side
For steel bar girder face；The steel bar girder face is embedded with steel bar girder and positioning corner brace；The height of siphonal lobe wall metope is more than internal lobe
Wall metope；When siphonal lobe wall and internal lobe wall overlapping are spliced into overlapping concrete plate, siphonal lobe wall positioning corner brace is fixed on internal lobe wall orientation angle
Siphonal lobe wall steel bar girder and internal lobe wall steel bar girder is mutually aligned and interlaced with each other at code, align on the siphonal lobe wall metope completed
Edge is higher than edge on internal lobe wall metope and siphonal lobe wall metope lower edge is flushed with internal lobe wall metope；In the external wall structure, contraposition is completed
Siphonal lobe wall, internal lobe wall between steel bar girder and siphonal lobe wall metope and internal lobe wall metope rear pouring concrete formation overlap concrete plate inside
Above attachment structure, floor slab structure, below it is affixed with internal lobe wall, upper strata siphonal lobe wall be located at lower floor's siphonal lobe wall on.
The floor slab structure includes floor and collar tie beam, and the internal lobe wall, which is poured, to be fixed at collar tie beam.
The siphonal lobe wall, the steel bar girder of internal lobe wall wind up muscle provided with truss；The truss wind up muscle upper end higher than outer
Edge on leaf wall metope and internal lobe wall metope；The siphonal lobe wall, internal lobe wall are poured and are fixed at collar tie beam with the truss muscle that winds up.
The one side of the non-reinforcing bar truss sides of internal lobe wall is leaf facade within the walls；Hound is provided with the floor slab structure；
Described hound one end is fixed at floor, and the other end is fixed on leaf within the walls at facade.
The one side of the non-reinforcing bar truss sides of siphonal lobe wall is leaf wall alien invasion；The leaf wall alien invasion from-inner-to-outer divides successively
For concrete flaggy, heat-insulation layer and exterior trim surface layer, steel bar girder is fixed at the concrete flaggy of the leaf wall alien invasion.
The upper strata siphonal lobe wall, the junction of lower floor's siphonal lobe wall are filled with pitch gluing layer.
Construction method comprises the following steps successively：
A1, in manufacturing process siphonal lobe wall and internal lobe wall carried out to spelling, siphonal lobe wall, which is positioned corner brace, is temporarily fixed on internal lobe wall
Position at corner brace, siphonal lobe wall steel bar girder and internal lobe wall steel bar girder is mutually aligned and interlaced with each other, form overlapping concrete plate；
A2, at the construction field (site) by lifting, the overlapping concrete plate A of setting posture is fixed at floor with hound；Make overlapping concrete
On plate A siphonal lobe wall along with upper strata floor and collar tie beam side wall close to or contact；
A3, overlapping concrete plate A pours and be fixed at the collar tie beam of upper strata floor with the truss muscle that winds up, and pass the truss muscle that winds up
Floor plate shape is into overlapping concrete plate fixing muscle, and then casting concrete overlaps concrete plate A's to strengthen at overlapping concrete plate A steel bar girders
Inside and outside leaf wall connection；
Another overlapping concrete plate B, is then placed in upper floor by A4, the laying flexible material layer at the upper end of overlapping concrete plate A siphonal lobe walls
At plate, overlapping concrete plate A overlapping concrete plate fixing muscle is anchored into and overlap the lamination portion of concrete plate B steel bar girders, make overlapping concrete plate B
Siphonal lobe wall lower edge is fallen within the flexible material layer of overlapping concrete plate A siphonal lobe walls upper end；
A5, repeat step A1 to A4, splicing overlapping concrete plate, and overlapping concrete plate is poured at each floor plate of building, stack
The mutual split of siphonal lobe wall alien invasion for closing concrete plate forms outside vertical surface of building.
Composite plate shear wall system is decomposed into different prefabricated components by the present invention（Siphonal lobe wall, internal lobe wall etc.）, in factory
Job site is transported to after interim splicing to be installed, so that the requirement to prefabricated component manufacturing equipment is substantially reduced, can be with a low price
The a large amount of double skin exterior walls of production of equipment, so as to improve yield and reduce cost.
