Description
Technical field
Architectural engineering cast-in-place structural reinforcement construction technology is the utility model is related to, is to be related to one kind to be used in particular
Control the Simple positioning device of shear force wall reinforcing steel bar array pitch.
Background technology
Cast-in-place structural shear force wall reinforcing steel bar typically uses double arrangement of reinforcement.Shear wall general section is small, number of steel bars multi-density is big,
The small poor rigidity of diameter, extruding, collision during model sheetinstallat to reinforcing bar, disturbance during disturbing concrete to reinforcing bar, hang draw and
The influence of the factor such as plant, personnel in work progress, easily makes reinforcing bar produce displacement, and mainly bar-spacing set becomes
Change, turn into construction quality common fault.It reduces structural elements bearing capacity, has a strong impact on architecture quality.Control shear wall steel at present
The design measure of muscle array pitch is to set " drag hook "；Working measure typically uses " ladder muscle ".It is mainly used for controlling shear wall two
The spacing of side steel bar stress, prevent from changing in work progress.It was verified that " drag hook " only controllable formative stage wall steel
The array pitch of muscle, subsequent handling influence is not resisted but, displacement can be still deformed in the presence of external force." ladder muscle " is using rule
Lattice are not less than the reinforcement fabrication of joist, and indulge muscle by both sides is equal to wall thickness with the length set perpendicular to vertical muscle, and spacing is equal to joist
The horizontal bar of spacing is welded.It is divided into vertical " ladder muscle " and level " ladder muscle ", while is arranged on wall as additional bar
Between the bar-mat reinforcement of both sides.Wherein vertical " ladder muscle " is highly the same as wall height；Arrangement spacing is 1.5m~2m.Horizontal " ladder muscle " arrangement
Under wall reinforcing bar, in, top, every layer is elongated setting." ladder muscle " is for controlling wall steel bar position in work progress
Effect is preferable.But because its amount of reinforcement is big, consider construction cost factor, it is only used for outside basement by most job sites
The significant points such as wall, other shear force wall reinforcing steel bar positions still fail to be effectively controlled.
In the construction of high-rise or super-high building structure, the load that armored concrete vertical structure is born is very big, wherein
As the reinforcing bar of skeleton, vital effect is played.And the position correctness of steel bar stress, it is directly connected to reinforcing bar effect
Performance and structural elements bearing capacity, it is necessary to paid attention to and taken seriously.In view of setting " drag hook " for controlling shear wall steel
The effect of muscle array pitch is limited, and " ladder muscle " is big because putting into, and cost is high, it is difficult to is generalized to bigger scope, at present shear force wall reinforcing steel bar
Position dominates the situation still severe including array pitch, it would be highly desirable to release it is more applicable, effective, conveniently, economic solution.
