Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment：
As shown in Fig. 1 ~ 7, the present embodiment is using reinforced concrete square columns as object is reinforced, using pre-stress FRP cloth to reinforcing bar
Concrete square column is reinforced, and FRP cloth width is 150mm.It is specific as follows：
A kind of device of reinforced steel concrete square column, including two bottom plates, 1, two tension ground tackle 2, the and of tensioning screw rod 3
FRP cloth 4.
Bottom plate 1 wraps up direction both ends inverted arc angle along FRP cloth 4, in case it scratches FRP cloth 4.Bottom plate 1 wraps perpendicular to FRP cloth 4
Wrap up in direction both ends and open up bottom plate anchor hole 11 and installation anchor hole 12 respectively.
The upper and lower ends of tension ground tackle 2 respectively open up two tension ground tackle anchor holes 21 perpendicular to the direction of FRP cloth 4.Tension ground tackle 2
Two screws 22 are opened up respectively along direction is wrapped up parallel to FRP cloth 4.
The surface of bottom plate 1 uniformly applies glue, and the both ends of FRP cloth 4 wind 2 circles after applying glue on bottom plate, make 4 liang of FRP cloth
End fixation is pasted onto on bottom plate 1.After colloid solidification, FRP cloth 4 reinforces opening position one week around reinforced concrete square columns 5.Tensioning
The tension ground tackle anchor hole 21 at the both ends of anchorage 2 is directed at the installation anchor hole 12 at the both ends of bottom plate 1, and crab-bolt 13 passes through tension ground tackle crab-bolt
