Description
Technical field
The present invention relates to build construction tool field, specially a kind of beam steel installation tool and its application method.
Background technology
In existing building construction process, the use of Vierendeel girder, very generally；But, architectural engineering middle frame joist steel
Muscle, which is installed, generally has following quality problems：
（1）When workman constructs, the row of beam top two, three placing of reinforcement not colligations, leakage are tied up or tied up less, cause each layer reinforcing bar clear spacing
It is excessive, the tension of Practical Project（It is pressurized）Reinforcing bar Resultant force is to tension（It is pressurized）The distance at edge（）Set much larger than theory
Evaluation, reduces beam section compression（Tension）The outward flange in area is to tension（It is pressurized）The distance of reinforcing bar Resultant force（）, reduction
The bearing capacity of structure.
（2）Beam bottom indulges muscle and has carried out colligation with stirrup position only in girder span, and vertical muscle does not form one with stirrup
Easy unstability after overall space framework of steel reinforcement, oblique section stress, is unfavorable for resistance beam diagonal tension failure, diagonal compression failure and shear compression failure shape
The oblique section destruction of state.
The reason for producing above-mentioned quality problems is, currently without construction tool of the invention for reinforcement installation, live work
People can only use U-shaped jacking when constructing.
