Detailed description of the invention
In Fig. 1 ~ 5, a kind of gate pier bracket Joint Re-bar Construction, comprise the following steps:
One, the place beyond gate pier makes reinforcing bar cage body 1, welds inner support 2 in reinforcing bar cage body 1；Preferably, channel-section steel inner support 2 is arranged in the middle part of reinforcing bar cage body 1.
Smooth location near steel bar meter district places sleeper draw-in groove, draw-in groove is used for being accurately positioned main muscle spacing bottom design bracket, laying reinforcing bar cage body 1 bottom layer of the reinforcing steel net according to design drawing, process the inner support 2 of dimension size simultaneously, preferred inner support 2 uses channel-section steel to process.Preferably employing 18# channel-section steel in this example, inner support 2 becomes frame structure, as shown in Fig. 1,3,4.Inner support 2 welds with bottom layer of the reinforcing steel net.Preferably, inner support 2 top uses round steel to be welded into 4 hangers, lifts by crane stress action spot as reinforcing bar cage body 1, and the top of inner support 2 is respectively to the brace 4 of bracket both sides 3 diameter 20mm of bottom welding.Single gate pier has both sides bracket, and the reinforcing bar cage body between the bracket of both sides is connected to an entirety as shown in Fig. 1,3,4.Preferably in scheme, it is fixedly provided with a hinge embedded part 9 in described reinforcing bar cage body 1, as shown in Figure 6.
Bracket reinforcing bar cage body 1 adds man-hour, the reinforcement welding of side and end face is carried out by design drawing, bracket horizontal connection reinforcement welding in the middle of the gate pier in two ends is formed and arranges rectangle channel-section steel inner support 2 in the middle of an entirety, reinforcing bar cage body 1, it is ensured that steel reinforcement cage rigidity during handling and stability.In the bracket steel reinforcement cage of two ends, steel plate and a hinge embedded part 9 are buried underground by design, and it is firm with reinforcing bar cage body 1 integral solder that a hinge embedded part 9 utilizes reinforcing bar sample rack to support.Preferably in scheme; each angle point and veil in reinforcing bar cage body 1 are provided with control point labelling, i.e. each angle point of reinforcing bar cage body 1 and each welding spacer bar, and reinforcing bar wire side is by the reserved protective layer thickness of design; preferably in scheme, described control point is labeled as the steel bar end of " T " font.Thus structure, with template sideline, corresponding with the reinforcing bar poured on pier concrete 7.So that gate pier two ends bracket reinforcing bar cage body 1 realizes in level land installation, a welded and installed molding, manual operation is simple and efficient, and it is convenient accurately that embedded part installs location.
Two, 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 gate pier, for the lifting location of reinforcing bar cage body 1 outline and load-bearing rest effect.Channel-section steel external support 3 uses 18# channel-section steel processing and fabricating.
Preferably in scheme, described reinforcing bar cage body 1 is the structure of similar cuboid, upper surface and lower surface are plane, and upper surface and lower surface parallel to each other, external support 3 is tilt stand, so that reinforcing bar cage body 1 keeps the angle of inclination of design after integral hoisting, one end that reinforcing bar cage body 1 props up hinge 10 near gate is relatively low.Such as Fig. 2, as shown in 7.
Three, pour pier concrete 7 be provided for support bracket bed die 5 overhanging scaffold support means 6；
