At the larger absolute altitude of installation site, the lower platform framework of steel reinforcement is located at the relatively small tenon eminence of precast stair installation site, upper flat
Bench stress truss bars net is connected between platform framework of steel reinforcement and lower platform framework of steel reinforcement；Steel bar stress net of marking time is set to bench
Stress truss bars are online；Bench stress truss bars be additionally provided on the net installation lifting anchor bolt, bench stress truss bars net with
The installation site of lifting anchor bolt is additionally provided with L-shaped suspension centre stiffener；The upper mounting plate framework of steel reinforcement, lower platform framework of steel reinforcement,
Bench stress truss bars net and steel bar stress net of marking time are wrapped in rigid plastics foam, and rigid plastics foam is externally provided with plastering
Fiber cloth mortar.
As preferred：Bench stress truss bars net side face is equipped with form removal swivel lifting anchor bolt.
As preferred：It is equipped with pin key reserving hole and correspondence on the upper mounting plate framework of steel reinforcement and lower platform framework of steel reinforcement
Reserving hole stiffener.
The utility model has the beneficial effects that:It, can be by the conduct of this teaching training apparatus during education activities are carried out
The teaching aids of precast rc slab formula stair uses, and professional teachers control is in kind and atlas is explained, and is conducive to
Grasp of the student to professional knowledge.At the same time, this teaching training apparatus replaces concrete with rigid plastics foam, greatly subtracts
Light dead load, the precast stair of 3m or so, total weight about 150kg, only comparable size concrete prefabricated stairs weight
1/10, student can complete installation and dismounting by small lifting equipment, break through the operative skill of student comprehensively, and ensure that
The safety of entire practice teaching.

Specific implementation mode
The utility model is described further with reference to embodiment.The explanation of following embodiments is only intended to help to manage
Solve the utility model.It should be pointed out that for those skilled in the art, not departing from the utility model principle
Under the premise of, several improvements and modifications can be made to this utility model, these improvement and modification also fall into the utility model
In scope of the claims.
As shown in Figures 1 to 8, the precast stair teaching training apparatus of this example includes upper mounting plate framework of steel reinforcement 1, lower platform
It is framework of steel reinforcement 2, bench stress truss bars net 3, steel bar stress net 4 of marking time, installation lifting anchor bolt 5, suspension centre stiffener 6, hard
Matter plastic foam 7, pin key reserving hole 8, reserving hole stiffener 9, plastering fiber cloth mortar 10, form removal swivel lifting anchor bolt
11 equal parts form.The upper mounting plate framework of steel reinforcement 1 is mounted at the larger absolute altitude of precast stair installation site, and by bench lotus
Load is effectively transmitted in floor structure；The lower platform framework of steel reinforcement 2 is mounted on the smaller absolute altitude of precast stair installation site
Place, and bench load is effectively transmitted in floor structure；The bench stress truss bars net 3 is carrying stair load
Main member, and deliver load to upper mounting plate framework of steel reinforcement 1 and lower platform framework of steel reinforcement 2, can in order to ensure that load transmits
By property, need bench stress truss bars net 3 connecting into stress in upper mounting plate framework of steel reinforcement 1 and lower platform framework of steel reinforcement 2 whole
Body；The effect for marking time steel bar stress net 4 is support 1-2 people in upper operation of marking time, and steel bar stress net 4 of marking time is needed with ladder
Duan Shouli truss bars nets are reliably connected；The hoisting point position in reasonable stress is arranged in the installation lifting anchor bolt 5, four altogether,
For in this actual training device installation process, being lifted by crane and being installed by component by small-sized hoisting device, installation lifting anchor bolt 5 must be with ladder
Duan Shouli truss bars nets are reliably connected；The suspension centre stiffener 6 is the strength and stiffness for reinforcing suspension centre region, improves installation
Lift by crane the reliability of anchor bolt working performance；The rigid plastics foam 7 is used to clog the gap between framework of steel reinforcement；The pin key is pre-
Box out the device of plan-position of the hole 8 for fixing precast stair in component mounting process, when precast stair position adjust with
Afterwards, reinforcing bar is inserted into pin key reserving hole 8, and casting concrete fixes precast stair；The reserving hole stiffener 9
Effect is to reinforce the intensity around reserving hole；The effect of the plastering fiber cloth mortar 10 is by framework of steel reinforcement and foam packet
Wrap up in into the stress entirety for having some strength and rigidity；The form removal swivel lifting anchor bolt 11 was produced in precast stair
Cheng Zhong hangs prefabricated components swivel when concrete strength reaches sufficient intensity (generally the 75% of concrete design strength)
It is attached to the boom hoisting that other places carry out maintenance.
The bench stress truss bars net is to carry the main member of stair load, and no concrete bonds reinforcing bar
Bench stress truss bars net is fabricated to truss structure by skeleton, and levels reinforcing bar forms stress entirety by truss tie-rod.Institute
It states rigid plastics foam and has certain intensity, it is main the reason is that quality is very light, it is of less demanding in entire element bearing capacity
Under the premise of (teaching training apparatus), using rigid plastics foam fill precast stair between framework of steel reinforcement can effectively mitigate knot
The weight of structure.Framework of steel reinforcement and foam are rolled into a stress for having some strength and rigidity by the plastering fiber cloth mortar
