The problems of the prefabricated composite beam are as follows:
as shown in fig. 7, the upper-layer steel bars of the precast beam are closed hoops, so that the risk of wrong insertion is high, when the precast steel bars cannot guarantee that the types, positions, lengths and the like of the longitudinal bars are completely correct, or when the field longitudinal bars cannot be correctly positioned, the closed hoops need to be cut to readjust the upper-layer steel bars, and the construction efficiency and the quality are seriously affected.
When the prefabricated composite beam, the composite slab and the prefabricated or cast-in-place column are installed, the upper longitudinal steel bars of the composite beam have full-length longitudinal steel bars, upper support negative steel bars (a first row and a second row), bottom steel bars and face steel bars of the composite slab and node area longitudinal steel bars and stirrups of the prefabricated column, when the components are installed, the problems of steel bar installation, position conflict and the like are more prominent, the problem of poor solution is solved, the installation quality and the installation progress of assembled components are seriously influenced, or the safety and quality hidden troubles of irregular or even wild construction are brought. How to deepen detailed design from the angle of BIM5d, improve processing and manufacturing fineness, reduce the difficulty of field installation operation and installation difficulty, and have positive significance for improving the construction of the accelerated assembly type component.
Disclosure of Invention

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the quick installation structure for the upper steel bars of the prefabricated composite beam comprises a prefabricated beam body 3, wherein exposed closed hoops 4 are embedded in the areas of two ends of the prefabricated beam body 3. The closed hoops 4 are positioned at the two end areas of the upper support of the precast beam body 3; an exposed opening hoop 5 is embedded in the position between the closed hoops 4 at the upper end and the two ends of the precast beam body 3, and the closed hoops 4 and the opening hoops 5 are arranged in a row. The split collar 5 comprises two opposed overhanging reinforcement bars 5-1.
Referring to fig. 5, the width of the prefabricated superposed beam is 250mm, and the opening of the overhanging reinforcement 5-1 in the open hoop 5 is smaller after bending (dotted line in the figure), so that one overhanging reinforcement 5-1 in the open hoop 5 is bent inward by 45 degrees, and the other overhanging reinforcement 5-1 is bent inward by 135 degrees. The prefabricated laminated slab is placed well, after the upper-layer steel bars penetrate through the prefabricated laminated slab, the left-side overhanging steel bars are bent inwards to 135 degrees by using the electric bending device.
Referring to fig. 6, the width of the prefabricated superposed beam is 300mm, and after the overhanging reinforcement 5-1 in the open hoop 5 is bent (dotted line in the figure), the opening is larger, so that the penetrating of the reinforcement is not hindered, and therefore, the overhanging reinforcement 5-1 in the open hoop 5 is bent inward by 135 °.
