The installation for carrying out stirrup, directly can be called in mounted reinforcing bar in template by the jack 5 after installation is complete.
It should be noted that need to carry out antidumping checking computations and bending stress checking computations before the auxiliary device comes into operation,
It can come into operation after meeting the requirements.By taking 8m cored slab reinforcement installation as an example, stull 3 and support post 2 are all made of Two bors d's oeuveres I14 slot
Steel, balance base 1 use I25 channel steel, and the auxiliary device used carries out bending stress and checks schematic diagram such as 4 institute of attached drawing used
Show, P=4.97KN, h=2.5m, L=2.5m, 1 width 1.5m of balance base.
Its bending stress is calculated:
Mmax=(4k+3)/(2k+3) * (PL/8), k=(I2/I1) * (h/L)=1
Then Mmax=2174.4N.m.
It meets the requirements.
The schematic diagram that the auxiliary device progress antidumping checking computations used use is as shown in Fig. 5, counts to its antidumping
It calculates:
The coefficient of friction of universal wheel 6 and mattess is 0.03, which weighs 450kg altogether.
F=FResistance=(G+P) * f=(4.5+4.97) * 0.03=284.1N
Calculation of Bending Moment M=F*h-G at wheelAlways* l=284.1*1.5-9470*0.5=-4308.85N.m < 0, therefore wheel
Can not bending moment, antidumping checking computations meet the requirements.
The schematic diagram that its 4 forcing checking of reinforcing bar of the auxiliary device used uses is as shown in Fig. 6, counts to its stress
It calculates:
U-shaped steel muscle both ends weld length is 14cm, and weld seam mode is overlap welding, the high h of weld seamf=5mm, P=4.97KN,
Reinforcing bar material and model HRB400 φ 20.
It is 360MPa that HRB400 φ 20, which designs tensile strength, can bear pulling force Fφ20。
FΦ20=360* π d2/4*10-3=360* π 202/4*10-3=113.1KN > 1.4P=4.97*1.4=6.958KN
Weld strength fwf=200MPa, fusion length B=140*2=280mm, weld seam effective area AW=0.7*hf* B=
980mm2。
Shear stress τ=P × 1.4/AW=4.97 × 1.4 × 103/ 980=7.1MPa < 200MPa
Therefore U-shaped welded reinforcement forcing checking is met the requirements.
