Embodiment
In Fig. 1 ~ 5, a kind of gate pier bracket Joint Re-bar Construction, comprise the following steps：
First, the place beyond gate pier makes reinforcing bar cage body 1, the welding inner support 2 in reinforcing bar cage body 1；Preferably, channel-section steel
Inner support 2 is arranged on the middle part of reinforcing bar cage body 1.
Smooth location near steel bar meter area places sleeper neck, and neck is used to be accurately positioned design bracket bottom master
Muscle spacing, the bottom layer of the reinforcing steel net of reinforcing bar cage body 1 is laid according to design drawing, while process the inner support 2 of dimension size, preferably
Inner support 2 is process using channel-section steel.18# channel-section steels are preferably used in this example, inner support 2 is into frame structure, such as institute in Fig. 1,3,4
Show.Inner support 2 welds with bottom layer of the reinforcing steel net.Preferably, the top of inner support 2 is welded into 4 hangers using round steel, as steel reinforcement cage
Body 1 lifts by crane stress action spot, and 3 diameter 20mm brace 4 is respectively welded at the top of inner support 2 to the side bottom of bracket two.It is single
Gate pier has a both sides bracket, and the steel reinforcement cage body phase between the bracket of both sides holds together as shown in Fig. 1,3,4.Preferable scheme
In, branch hinge embedded part 9 is fixedly provided with described reinforcing bar cage body 1, as shown in Figure 6.
When bracket reinforcing bar cage body 1 is processed, the reinforcement welding of side and top surface is carried out by design drawing, both ends bracket is in gate pier
Between horizontal connection reinforcement welding form an entirety, rectangle channel-section steel inner support 2 is set among reinforcing bar cage body 1, it is ensured that steel reinforcement cage
Rigidity and stability during handling.Steel plate and branch hinge embedded part 9 are buried by design in the bracket steel reinforcement cage of both ends, branch hinge
Embedded part 9 is firm with the integral solder of reinforcing bar cage body 1 using the support of reinforcing bar sample rack.In preferable scheme, at each angle of reinforcing bar cage body 1
Point and veil mark provided with control point, i.e. 1 each angle point of reinforcing bar cage body and each face welding spacer bar, reinforcing bar wire side is pre- by design
Stay protective layer thickness, in preferable scheme, described control point is labeled as the steel bar end of " T " font.Thus structure, with and template
Sideline, and the reinforcing bar poured on pier concrete 7 are corresponding.Pacify so that gate pier both ends bracket reinforcing bar cage body 1 is realized on level land
Dress construction, a welded and installed shaping, manual operation is simple and efficient, and embedded part installation positioning facilitates accurate.
2nd, pier concrete 7 is being poured and is being provided for the external support 3 of spacer bar cage body 1；External support 3 is arranged in lock
In pier, lifting positioning and the effect of load-bearing rest for the outline of reinforcing bar cage body 1.Channel-section steel external support 3 is using 18# channel-section steels processing system
Make.
In preferable scheme, described reinforcing bar cage body 1 is the structure of similar cuboid, and upper surface and lower surface are flat
Face, and upper surface and lower surface are parallel to each other, external support 3 is tilt stand, so that reinforcing bar cage body 1 keeps setting after integral hoisting
The angle of inclination of meter, reinforcing bar cage body 1 are relatively low close to one end of gate branch hinge 10.As shown in Fig. 2,7.
3rd, pier concrete 7 is being poured and is provided for supporting the overhanging scaffold support meanss 6 of bracket bed die 5；
Bracket bed die 5 blocks big plane template using gate pier more and employs overhanging scaffold support, obtains overhanging type pin hand
Rack supporting device 6.The collateral point of gate pier has more strap form locating cones and B7 bolts.As shown in Fig. 1,2.
