Description
Technical field
The utility model relates to construction engineering technical field, is specifically related to a kind of overlapped shear wall with shearing resistance keyway.
Background technology
To bear horizontal loading and vertical load (gravity) ability that wind load or geological process cause strong due to it for shear wall structure, can prevent that structure from shearing (being cut) and destroying; Meanwhile, shear wall, because its cross-sectional width is little, in residential housing, does not affect service function of the rooms, therefore shear wall structure is the first-selected version in high residential building.
In recent years, assembled architecture has obtained very fast development, existing professional standard " prefabricated concrete structure technical regulation " JGJ1-2014 specifies that solid shear wall can adopt metal sleeve grouting to connect or slurry anchor overlap joint connects, due to reserved sleeve or reserved opening allowable error little, on-the-spot joint bar quality is difficult to ensure, causes speed of application slow; In addition, post-grouting packing is difficult to ensure, and the remedial measure not had.
In view of this, the applicant provides a kind of overlapped shear wall with shearing resistance keyway, and this case produces thus.
Utility model content
The purpose of this utility model is to provide a kind of overlapped shear wall with shearing resistance keyway, and overlapped shear wall plate scene is easy for installation, and speed of application is fast, and inside and outside two-layer precast slab base plate arranges shearing resistance keyway, is highly resistant to horizontal loading and geological process.
For realizing this technical purpose, the technical scheme that the utility model specifically provides is: a kind of overlapped shear wall with shearing resistance keyway, comprises inside and outside two-layer precast slab and middle cast-in-place concrete layer; Between described inside and outside two-layer precast slab, connect by steel bar girder; Described inside and outside two-layer precast slab bottom arranges shearing resistance keyway; In described inside and outside two-layer precast slab, be provided with horizontal reinforcement and vertical reinforcement; The top end face of described inside and outside two-layer precast slab is provided with the suspension hook for lifting; Described internal layer precast slab is provided with the built-in fitting for installing.
Further, described overlapped shear wall gross thickness is 200 ~ 300mm, and described internal layer precast slab or outer preform concrete slab thickness of slab are 50mm.
Further, described suspension hook is two, is distributed in the top of described overlapped shear wall.
Further, described built-in fitting is two lifting sleeve pipes, and described built-in fitting is 2/3rds of overlapped shear wall total height to the distance on overlapped shear wall base.
A preparation method for overlapped shear wall with shearing resistance keyway, specifically comprises the steps: a, the loose tool mould of clearing up and aid the border areas, and arranges shearing resistance keyway and built-in fitting according to drawing, spraying releasing agent; Precast slab horizontal reinforcement, vertical reinforcement, steel bar girder and suspension hook in b, layout; C, interior precast slab are built and are vibrated, and check and adjust maintenance; D, layout outer preform concrete slab horizontal reinforcement and vertical reinforcement, and build outer precast slab; E, after being turned over to turnback, interior precast slab is pressed in outer board concrete; Maintenance is adjusted in f, the inspection of vibrating, and after maintenance completes, the demoulding rises and deposits.
A construction method for overlapped shear wall with shearing resistance keyway, comprises the steps, a, flooring cleaning, and unwrapping wire and absolute altitude control cushion block are placed; B, vertical joint bar adjustment, the prefabricated board lifting of overlapped shear wall is in place; C, bearing diagonal are installed coarse adjustment, unload suspension hook accurate adjustment, and arrange steel bar girder, formwork horizontal joint and edge member; D, inspect for acceptance, and carry out concreting maintenance, last bearing diagonal is removed.
The beneficial effects of the utility model: structure of the present utility model is assembled monolithic concrete structure, the advantages such as anti-seismic performance is good, construction install convenience, saving duration that it has.
