Description
Technical field
The present invention relates to a kind of assembly concrete staircase external wall structure and its construction method, belong to armored concrete knot
Structure field of engineering technology.
Background technology
At present, prefabricated assembled concrete staircase exterior wall assembling structure or all using prefabricated load-bearing shear wall plate,
Or all using plug-in non-bearing out-hung panel, there is problems with both constructions：
1. following problem is configured with using prefabricated load-bearing shear wall plate all：A. exterior wall is long, and rigidity is big, but marks time position
Put out big hole and contact weak with agent structure；Unbraced length is long, and wall stability has hidden danger；Itself deadweight is subjected only to, material does not fill
Divide Developed fiber strength.B. the conventional shears ladder of high residential building, generally requires in the middle part of exterior wall, and a section medium position of marking time sets up connection two
The cast-in-place post of block plate, the cast-in-place part formwork are loaded down with trivial details；C. it is because of section non-floor at the floor absolute altitude of marking time, temporarily solid in installation process
Determine precast shear wall difficult.
2. following problem is configured with using plug-in non-bearing out-hung panel all：Staircase span is big, is usually placed in building
The outside of layer plane, and protrusion is more, under geological process, torsional effect substantially, is difficult to meet the requirement of specification when floor is higher.
The content of the invention
In order to solve that the prefabricated assembled concrete staircase exterior wall routine wall limb stability brought of assembling structure is poor, construct
The problem that difficulty is big and torsional effect is big, it is an object of the present invention to provide a kind of prefabricated assembled concrete staircase exterior wall
Assembling structure.
In order to realize above-mentioned task, the present invention adopts following technical solution：Outside a kind of assembly concrete staircase
Wall construction, it is characterised in that including prefabricated load-bearing longitudinal direction shear wall slab, prefabricated load-bearing transverse shearing force wallboard, precast beam, non-bearing
Out-hung panel and link plate connector, in half space Outboard Sections using the prefabricated load-bearing longitudinal direction shear wall slab and prefabricated load-bearing
Transverse shearing force wallboard, adopts the precast beam and non-bearing out-hung panel in step plate Outboard Sections；The prefabricated load-bearing longitudinal direction
Shear wall slab, its side are connected with the cast-in-place edge member of staircase by laterally attached reinforcing bar, and opposite side is taken by reserved steel bar
Connect region to be connected with precast beam, and be connected with stair stringer and half space floor in its vertical direction；The prefabricated load-bearing is horizontal
Shear wall slab, its left and right sides are connected with the cast-in-place edge member of staircase by laterally attached reinforcing bar, and its vertical direction with
Half space floor connects.
Further, non-bearing out-hung panel combines to form flexible connection structure with the link plate connector of staircase agent structure
Make, the displacement mode that the construction is combined with translation using rotation displacement mode or rotation.
Further, the edge joint position of the non-bearing out-hung panel is blocked using the sealing joint strip.
Further, the connecting node structure of the reinforcement detailing, link plate connector and agent structure of the non-bearing out-hung panel
Making should be according to bearing capacity and normally being checked using two kinds of limit states.
Further, link plate connector combines to form flexible connection construction, reduces response of the structure under geological process, it is ensured that
Non-bearing out-hung panel adapts to the maximum story drift of agent structure under geological process.
The invention also discloses assembly concrete staircase external wall structure construction method, comprises the steps：
First, the non-bearing out-hung panel is first lifted to specified location, add temporary support, adjust the link plate connection
Part makes height, axial location and the perpendicularity of the non-bearing out-hung panel meet requirement；
Second, the precast beam is then lifted to specified location, beam two ends are placed on the prefabricated load-bearing longitudinal direction shear wall
In the interim support pre-set on plate, node concrete is poured；
3rd, the connection of the precast beam and the non-bearing out-hung panel is fixed by the link plate connector；
4th, blocked with building sealant, to ensure the prefabricated assembled concrete staircase exterior wall assembling structure
Water resistance.
Further, in second step, precast beam is placed on the precast beam of prefabricated load-bearing longitudinal direction shear wall slab side when constructing
Interim support on, two components are poured together by the cast-in-place region being reserved on the shear wall slab of prefabricated load-bearing longitudinal direction.
Beneficial effect：Present invention is mainly used for the articulated constuction design of prefabricated assembled concrete staircase exterior wall, solution
The wall limb stability that certainly the conventional assembling structure of prefabricated assembled concrete staircase exterior wall is present at present is poor, and difficulty of construction is big and right
Structure integral rigidity affects excessive problem.The present invention is applied to the stair of many high level prefabricated assembled concrete shear wall structures
Between exterior wall assembling structure.
Assembly concrete staircase external wall structure of the present invention, with tradition all using prefabricated load-bearing shear wall plate construct,
Or all compared using the construction of plug-in non-bearing out-hung panel, employ prefabricated load-bearing shear wall plate and plug-in non-load bearing wall
The make that plate combines, has the advantages that from heavy and light, wall limb good stability, structure anti-torsion effect be good, easy construction, tool
The present the following aspects of body surface：
1）From heavy and light.Non-bearing out-hung panel can be facilitated construction transport and lifted, reduced structure certainly using light material
Weight.
2）Wall limb good stability.Prefabricated load-bearing shear wall plate is provided only on half space part, has floor plates to support up and down,
The unbraced length of wall limb is little, good stability.
3）The antitorque effect of structure is good.The structure of prefabricated load-bearing shear wall composition has good torsional rigidity, can reduce
Structure because reversing the deformation for producing under geological process, do not destroy under little shake by protection structure.
4）Easy construction, low cost.With all using the construction of prefabricated load-bearing shear wall plate compared with, reduce concrete
Native load-bearing wall panel straight screw sleeve connection quantity, eliminates the cast-in-place sleeper between two blocks of wallboards, facilitates construction, reduce cost,
Job site connection hidden danger is reduced, build guality is improve.
