The present invention relates to a kind of assembled steel reinforced concrete hollow building roof structure, especially a kind of wide cut hollow superimposed sheet and
Its preparation method, belongs to buildings in general construction field.
(2) background technology
Assembled architecture has the characteristics of factorial praluction degree is high, speed of application is fast, integrated cost is low, this kind of structure shape
Formula is just obtaining country and widelyd popularize at present.
For span in below 5m precast assemble floor, common superimposed sheet can just solve；But in more than span 5m,
Especially span exceedes 7m superstructure, according to common solid superstructure then structure from great, poor seismic behavior, and comprehensive warp
Index of helping is relatively low.For building cover structure, no matter cast-in-place or iterative structure, village hollowing is exactly solve the problems, such as large span one
Plant technological means.
Before 2004, traditional superposed floor maximum span is no more than 6m, later, and Xu Youlin, Wang Xiaofeng etc. propose " pre-
Stress bidirectional superposition slab " (CN2642887Y), its main technical schemes have：1st, superstructure bottom is prefabricated, and top is cast-in-place, in superstructure
A direction spliced side by side using polylith prestressing force prefabricated panel；2nd, the horizontally-spliced use monoblock type piece of prefabricated panel, side
Side thickness suitably reduces, and the reinforcing bar that plate side is stretched out is anchored in opposite side cast-in-place concrete layer is stretched into after edge joint position is overlapped and is bent,
And set 2 reinforcing bars to strengthen anchoring in piece reinforcing bar bending place；3rd, high-strength helix rib steel wire or three strands of steel strand wires are made in
For prestress reinforcement；4th, it can put lightweight non-bearing material in rear pouring concrete overlapping layers to strengthen floor insulation, sound insulation
Etc. performance.The proposition of CN2642887Y technologies, its engineering construction span can reach 9-10m, and superimposed sheet is greatly facilitated

But there is following defect in CN2642887Y：1st, because CN2642887Y uses relatively large " the high-strength spiral shell of diameter
Revolve rib steel wire or three strands of steel strand wires " cause prefabricated panel thickness generally all >=60mm, cause prefabricated panel deadweight larger, construct tired
The maximum of difficult and floor uses span also restrained；2nd, as prefabricated panel thickness≤80mm, the rigidity of its own is smaller, hangs
Fill difficulty of construction larger；3rd, because prefabricated panel deadweight is larger, limited by building machinery hoisting weight, as floor span >=9m
When, width typically all≤1.2m of every piece of prefabricated panel, same plate needs many block prefabricated panels to be spliced, piece many one
It is that the reinforcing bar consumption of piece area is more, two be that construction workload is big.In CN2642887Y, also it is proposed that " putting lightweight non-in floor
Load-bearing material ", but it is only limitted to put in rear pouring concrete overlapping layers, is anticipated for the deadweight for mitigating prefabricated panel without actual
Justice.
2004, height is even beautiful to propose " prestressed concrete overlapped slab " (CN2706530), and its structure is：Prestress steel

Between switching performance it is poor, be only applicable to one-way slabs, the rigidity perpendicular to prefabricated components length direction is small, construction hoisting is difficult.
After 2012, Wu Shunhong etc. successively proposes " honeycomb hole type rib frame prestressed reinforced concrete superimposed sheet "
(CN102995805A) and " a kind of box light-duty superimposed sheet of prestressed concrete " (CN203603332U), it has following respectively
Defect：1st, prefabricated component hollow rate it is small, from great；2nd, switching performance is poor between adjacent preforms, is only applicable to one-way slabs.
2015, Wang Donghui etc. proposed " prestressed concrete superimposed sheet with ribbing " (CN204609075U), its major technique
Scheme is：Superimposed sheet includes prefabricated panel and concrete layer, and prefabricated panel is made up of bottom plate and floor, and floor includes L-shaped and T-shaped
Two kinds, polystyrene foam warming plate is filled between floor, concrete layer is provided with prefabricated panel.Its defect is：
Switching performance is poor between adjacent preforms, is only applicable to one-way slabs.
