beam stirrup of the present invention is the form that end is bent into 135 degree of crotches, it is U-shaped to form that one is long and the other is short, beam hooping structure form described in two kinds, it is U-shaped that beam stirrup is that one is long and the other is short, after beam main tendon colligation completes, be bent into closed ring-type, the beam main tendon after bending forming can be made directly to penetrate in two-sided superposed beam, the inconvenience bent again after saving colligation.
girder rib section of the present invention is right-angled triangle, article one, bottom level right angle limit and beam stirrup, minor face and two sides form statically determinate structrue, described girder rib section is triangle, intensity can ensure that beam reinforcement cages is stablized, and stacks and lifts indeformable, due to the existence of girder rib, make the statically determinate structrue that two-sided superimposed beam reinforcement cages is formed, not yielding, can ensure that product is in transport and the stability of hoisting process, the beam section size after guarantee survives.
the precast concrete plank surface that two-sided superposed beam of the present invention is used for outdoor side can arrange insulation layer or arrange insulation layer and decorative layer simultaneously, after two-sided superposed beam completes, be transported to job site, mounting condition to be achieved, support is set, fixing bed die, lift two-sided superposed beam, adjust its position and absolute altitude, colligation beam main tendon, beam main tendon is connected by butt welding, tie up bar to be welded to connect, the mode spreadings such as overlap joint connection and mechanical connection, after floor installation, the sealing gap, position such as precast concrete plank and bottom template, build, vibrated concrete maintenance, complete the construction of two-sided superposed beam, can realize once surviving, reduce operation.
the invention solves nine-squares beam and primary-secondary beam intersection can not the difficult problem of precast assembly, and colligation after Nodes beam main tendon, ensures node security.
be cavity in the middle of the precast concrete plank of both sides of the present invention, beam main tendon can after prefabricated units installation, penetrate and colligation, the modes such as beam main tendon can utilize traditional reinforcement welding to connect, overlap joint connection, straight screw sleeve connection, taper thread sleeve connection, compression sleeve connection, beam main tendon colligation is convenient, and quality of connection easily ensures.
two-sided superposed beam inside of the present invention is cast-in-situ concrete, and form T-type structure with plate cast-in-place concrete, overall performance is strong.
two-sided superposed beam of the present invention, can according to the Specific construction situation of two-sided superposed beam, precast concrete plank lower inside or upper design are become the cross section of level and smooth reduction, also can be turned upside down in the cross section of the level and smooth reduction inside precast concrete plank placement, to solve the problem that precast beam falls plate node and above returns girder connection difficult treatment.
