In order to solve the above technical problems, the technical solution of the utility model is：Assembled assembled stair, including two opposite set
The stair stringer and the multistage step plate between two stair stringers set；Each stair stringer includes that cant beam and setting exist
The landing beam at the cant beam both ends, the upper surface of the cant beam are equipped with the multi-stage stairs of stepped arrangement, every grade of step
On be equipped with connector；Every grade of step plate includes and the matched L-shaped step plate ontology of the step, the step plate
Ontology includes the tread portion as tread and supports the support portion in the tread portion, and the both ends in the tread portion are respectively equipped with installation
Hole, the connector are arranged in the mounting hole.
As an improvement positioning groove is equipped on the inside of every grade of tread portion, in step plate described in adjacent two-stage,
The support portion of step plate described in upper level is set in the positioning groove of step plate described in next stage.
As an improvement being equipped with grouting material between the mounting hole and the connector.
As an improvement the cant beam is equipped with deformed bar.
As an improvement the connector is wholely set with the stair stringer.
As a further improvement, the connector is pin key.
After using above-mentioned technical proposal, the utility model has the beneficial effects that：
Due to assembled assembled stair, including two be oppositely arranged stair stringer, the multistage between two stair stringers
Step plate and connector；Stair are thus split as stair stringer and step plate, transport easy to produce is obviously reduced in scantling,
Step plate is connected by precast stair joist support support, by connector, is easily installed；Board mold high recycling rate of marking time and convenient for repairing
Reorganization is closed；Stair stringer, step plate can be completed in factory's concentration pre-casting, and manufacturing process realizes batch production and digitlization, size pole
Its standard can reach the millimetre-sized level of industry；Low to site requirements, energy conservation and environmental protection, assembling is simple, convenient disassembly, can be with
It greatly shortens the construction period, and can repeatedly move dismounting, recycling rate is high, forms huge economic interests.This practicality is new
The assembled assembled stair that type provides, speed of production is fast, low cost, is easily installed transport, and production process is simple, and combines
Flexibly.
Due to being equipped with positioning groove on the inside of tread portion described in every grade, determining for step plate can be realized by positioning groove
Position, it is convenient for assembly.
Due to being equipped with grouting material between the mounting hole and the connector, step plate and stair can be realized by grouting material
Beam is reliably connected, and at low cost, easy to use.
Since the cant beam is equipped with deformed bar, the intensity of cant beam can be improved.
Since the connector and the stair stringer are wholely set, the connection of connector and stair stringer is facilitated, and can be with
Reduce the quantity of parts, ease of assembly.
