Walk plate；Another end bar is stretched out and is bent, for hooking the reinforcing bar of stair main structure plate；
(2) make step plate: after binding step plate reinforcing bar, the support plate that will mark time is vertically placed to step plate side as baffle, pours
Build concrete；One end bar is stretched out and is bent, for hooking the reinforcing bar of stair main structure plate；
(3) it is prefabricated that whole stair are completed: binding stair main structure slab muscle；Several step plates are arranged, the lateral steel of step plate
Muscle and the transverse steel for support plate of marking time hook stair main structure plate longitudinal reinforcement respectively；Casting concrete completes whole building
Ladder is prefabricated.
Compared with the prior art, the invention has the following advantages:
1, it is prefabricated in the factory, then constructs to on-site consolidation.Compare cast-in-situ stair, standardization level height, short construction period, Cheng Pinzhi
It measures.
2, stair are resolved into three finite elements plates, is prefabricated in the factory, implements step by step respectively, will sequentially marked time
Plate and support plate rigid connection of marking time, and then mixed by concrete integrated cast structure at completely prefabricated with stair main structure plate
Solidifying Tulou ladder.Compare the marking time with staircase boards in the form of bolted splice of reassembling type stair, this product be it is integral prefabricated, it is all
Connection is rigid connection, has better anti-seismic performance.
3, step plate and its support plate of marking time are rigid with stair main structure plate rock-steady structure triangular in shape again after being rigidly connected
Connection, triangle interior are hollow state.It compares prefabricated solid stair and saves stair under conditions of equivalent constructions performance
20% or more overall material utilization amount, reduces the overall weight of stair.

Specific embodiment
1-5c is further described the present invention with reference to the accompanying drawing: as shown in Figs 1-4, a kind of limited destructing preformed rigid
The hollow stair of connection structure, including stair main structure plate 1, support plate of marking time 2 and step plate 3, are plate-like piece；The main knot of stair
Structure plate 1 is to be made of reinforcing bar and concrete, and stair main structure plate transverse steel 10 and stair main structure plate longitudinal reinforcement 11 are bound,
Stair main body frame is formed, after concreting, axial cross section is trapezoidal；It is set between floors when by stair main structure grillage
When, it is just parallel to the ground with the end face of floor lap-joint；Support plate of marking time 2 is mark time support plate transverse steel 20, branch of marking time
The prefabricated component that fagging longitudinal reinforcement 21 and concrete are constituted, 20 one end of support plate of marking time transverse steel are stretched out, mark time for protruding into
Plate 3, the other end are stretched out and are bent, for engaging with stair main structure plate longitudinal reinforcement 11；Step plate 3 is step plate transverse steel
30, the prefabricated component that step plate longitudinal reinforcement 31 and concrete are constituted, 30 one end of step plate transverse steel stretch out and bend to it is hook-shaped,
For engaging with stair main structure plate longitudinal reinforcement 11.
Rigidly connect with staircase structure mainboard rock-steady structure triangular in shape again after step plate and its support plate rigid connection of marking time
It connects, triangle interior is hollow state.The both ends of the surface for support plate of marking time are bonded with step plate, stair main structure plate respectively, are marked time
One end face of plate is bonded with stair main structure plate face, and another end section is rectangle, in order to be bonded the bottom face for support plate of marking time,
A boss is arranged in the tail end of stair main structure plate.
As illustrated in figs. 5 a-5 c, a method of prepare the hollow stair of limited destructing preformed rigid connection structure, including with
