nullThe assembled T-shaped mixing coupled wall of the present invention,It is to use assembled combinative structure,Node design studies is connected for T-shaped in assembled mixing coupled wall system,Based on finite element theory,Set up FEM (finite element) model and assembled T-shaped mixing coupled wall system is carried out mechanical analysis,Verify the reliability of its node,Bonding strength is high、Node quality is good: first,Wall unit is reinforcing bar、Shaped steel and the mixed structure of concrete,Fixed by seam short beam butt welding between wall unit,Seam short beam after butt welding forms shaped steel short beam in seam post-cast strip,This is the important channel of node power transmission,And weldquality is more readily detected,It is also easier to guarantee quality of connection,So,Just define between wall unit and be reliably connected,Formation is similar to Shu Zhuti system,Twice seam short beam on monolayer wall unit and anchor ring muscle,Add intensity and the ductility of seam horizontal direction;The existence of anchor ring muscle, make rear pouring concrete that class Shu Zhuti system is had diagonal bracing effect, ensure that the bonding strength between wall unit, in addition, if seam short beam is divided into stem portion original whole surface concrete wall, concrete is served Confinement effect, add the comprcssive strength of concrete, simultaneously, the vertical muscle in seam post-cast strip and seam post-cast strip stirrup it is additionally provided with in seam post-cast strip, this all has obvious effect to improving concrete crushing strength, add intensity and the ductility of seam vertical direction, therefore, the node strength of assembled T-shaped of the present invention mixing coupled wall is higher than component strength, meet anti-seismic construction requirement.
The construction method of the assembled T-shaped mixing coupled wall of the present invention is the easiest, fast, efficiently, it is included in prefabrication, assemble at the scene, after seam short beam butt welding, greater stiffness has been formed between wall unit, be conducive to stablizing of body of wall in work progress, and two procedures can be carried out simultaneously, improve speed of application, for project under construction complete on schedule provide guarantee, consider that mixing coupled wall unit makes, lift and transport is convenient, component is split and is classified into standard component wall unit, after being transported to job site, reliable with being connected, the node structure being easy to construction carries out supporting assembling, during project construction, assembling combination between structure, decrease the wet trade amount that concrete is on-the-spot, thus decrease template, the input amount of temporary support, and then decrease the generation of building waste.
Present invention accomplishes that mixing coupled wall system antidetonation needs, achieves prefabrication, on-site consolidation synchronizes the form of construction work that carries out, seam post-cast strip ensure that the reliability that node connects.
Compared with tradition cast-in-place concrete coupled wall, girder steel is used to substitute beams of concrete, steel column is used to substitute edge constraint armored concrete sleeper, make to mix coupled wall and have more preferable energy dissipation capacity and progressive collapse-resisting ability than traditional coupled wall, seam beam is used to substitute embedded bar, owing to seam beam is bigger than reinforcing bar rigidity, transportation does not haves bending phenomenon, ensure quality, and prefabrication and in-site installation are carried out simultaneously, solve the problem that job site wet trade amount is big, building waste is many, it is simple to meet building and use requirement and simplify assembly process;Compared with existing general assembled coupled wall, after seam short beam butt welding, greater stiffness has been formed between wall unit, be conducive to stablizing of body of wall in work progress, eliminate precast shear wall and do the operation of temporary support, ensure that efficiency of construction, reduce the input amount of template temporary support, decrease the generation of building waste.
The composite can be widely applied to architectural engineering mixes the construction of coupled wall structural system.
