Fabricated shear wall levels attachment structure
The present invention relates to building structure field, particularly a kind of fabricated shear wall levels attachment structure.
At present, the shear wall structure of traditional cast-in-place form exist that work on the spot amount is big, construction material waste many, for building
The problems such as water waste, environmental pollution are serious.Adopting sleeve to fill built fabricated shear wall structure wall vertical connection structure more
Slurry connects, reinforcement welding connects and indirectly overlaps slurry anchor connection.Sleeve grouting connection has sleeve high cost, construction precision
The problems such as have high demands, be not suitable for the thinner reinforcing bar in section and adopt；Reinforcement welding connects and exists that Site Welding workload is big, welding
The problems such as difficult quality guarantee；Indirectly overlap joint slurry anchor connection has that site operation difficulty is big, preformed hole forming quality is difficult to protect
The problems such as card, and sleeve grouting connects and indirect overlap joint slurry anchor connection belongs to dry connection, if dealt with improperly, in horizontal joint
Easily stress concentration phenomenon in place, forms plane of weakness, the overall performance of impact structure.
Content of the invention
The present invention provides a kind of fabricated shear wall levels to connect for solving technical problem present in known technology
Structure, this structure positioning accurately, easy construction, shear resistance strong.
The present invention is adopted the technical scheme that by solving technical problem present in known technology: a kind of assembled shearing
Wall levels attachment structure, is provided with downwardly projecting platform in the middle part of the bottom surface of upper walls, on the bottom surface of described downwardly projecting platform
It is provided with shearing resistance groove；It is embedded with channel-section steel or I-steel in the middle part of the top surface of lower floor's wall；Described downwardly projecting platform is seated in described lower floor
On the top surface of wall, described channel-section steel or I-steel are inserted in described shearing resistance groove, described channel-section steel or I-steel by after pour described anti-
Cut the xoncrete structure in groove to be fixed in described shearing resistance groove, form positioning-shear structure.
The bottom surface positioned at described downwardly projecting platform both sides of described upper walls is the inclined-plane gradually rising from inside to outside,
The lower section on described inclined-plane, the vertical distribution bar of described upper walls overlap joint corresponding with the vertical distribution bar of described lower floor wall, institute
State inclined-plane and form wedge structure with the top surface of described lower floor wall and the side of described downwardly projecting platform, in described wedge structure
Wedge shape xoncrete structure is poured after being inside formed with.
The vertical distribution bar of two outermost of described upper walls is all being connected with the spacer bar thicker than them within the walls, institute
State spacer bar to extend to accordingly below described inclined-plane, the lower end of described spacer bar is connected with nut by screw thread, described
Nut support, on the top surface of described lower floor wall, forms regulation-supporting construction.
The absolute altitude of the vertical distribution bar in described wedge structure of described lower floor wall is gradually lowered from the outside to the core.
In the vertical distribution bar of described fabricated shear wall, positioned at vertical point of described positioning-shear structure both sides
Cloth reinforcing bar is the reinforcing bar of overstriking.
The present invention has the advantages and positive effects that:
One) positioning-shear structure in attachment structure, makes positioning more precisely and simple；Meet middle part shearing resistance requirement；
The attachment structure traditional with respect to sleeve connection etc., reduces difficulty in assembling process for the precast wall body, makes construction more just
Two) regulation-supporting construction in attachment structure, jointly serves good in construction with positioning-shear structure
Supporting role；Pass through screw on nut simultaneously, levelness and the perpendicularity of upper walls can be adjusted exactly, improve construction accurately
Three) pour wedge shape xoncrete structure after in attachment structure, make the vertical distribution bar of body of wall only need to be overlapped
Connection can meet requirement, with sleeve connection, be welded to connect and indirect slurry anchor connection compared with construction get up more simple and easy to do；?
Changed to middle stress by two ends according to shear wall in wedge structure, be gradually reduced lapped length of steel bar, so that material is filled
Divide and utilize, saved construction cost.
In sum, the present invention pass through using positioning-shear structure, regulation-supporting construction and after pour wedge shape concrete tie
Structure, makes body of wall levels connection construction simpler, and positioning is more accurate, and structure is more reliable, and performance more optimizes, and takes full advantage of material
Performance, efficiently solves the problems such as existing connected mode site operation is difficult, cost is high.The sleeve of relatively current employing fills
The connected modes such as slurry, improve construction precision, simplify construction procedure, and greatly reduce the cost of product and work progress,
There is good development prospect.
