In order to achieve the above purpose, the utility model adopts the following technical scheme:
a steel bar positioning device for a section broken box girder comprises a base plate, a plurality of first fixing clamping grooves and two second fixing clamping grooves, wherein the plurality of first fixing clamping grooves and the two second fixing clamping grooves are fixed on the upper surface of the base plate; each first fixed clamping groove and each second fixed clamping groove are made of angle steel plates with acute included angles.
After the broken box girder reinforcing steel bar positioning device is used, the size of the web framework is controlled, and the qualified rate of the protective layer is obviously improved; the reinforcing bar is through fixed, and the deformation is less in the installation, has made things convenient for the construction for the efficiency of construction.
Preferably, each first fixing clamping groove is located on the outer side of the steel bar, and the opening direction of each first fixing clamping groove faces the steel bar.
Preferably, the included angle between each first fixed clamping groove and each second fixed clamping groove is 40-60 degrees.
Preferably, the fixing device further comprises a plurality of rows of third fixing clamping grooves.
Preferably, the device further comprises a movable limiting part, wherein the movable limiting part comprises a cross rod, two left longitudinal rods arranged at the left part of the cross rod and two right longitudinal rods arranged at the right part of the cross rod; two left vertical poles and two right vertical poles all are located the horizontal pole homonymy, and the clearance between two left vertical poles and the clearance between two right vertical poles all cooperate with the reinforcing bar.
Preferably, the base plate is provided with a plurality of connecting rods for connecting with the ground.
Therefore, the utility model discloses following beneficial effect has: the size of the web framework is controlled, and the qualification rate of the protective layer is obviously improved; the reinforcing bar is through fixed, and the deformation is less in the installation, has made things convenient for the construction for the efficiency of construction.
