Description
Technical Field
The invention relates to the technical field of precast concrete stairs, in particular to a novel light honeycomb hole profiled steel sheet stair.
Background
The precast concrete stair is more and more extensive because of advantages such as its green convenient transportation, and current precast concrete stair, it is with high costs, need put into the mould after the reinforcement and then grout and produce. In the process of binding the reinforcing steel bars, the time and the labor are consumed, the production efficiency is low, and the traditional precast concrete stairs are heavy. Therefore, a novel light honeycomb hole profiled steel plate stair is provided.
Disclosure of Invention
The invention aims to provide a novel lightweight honeycomb hole profiled steel plate stair to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a novel light honeycomb hole profiled sheet stair, includes stair main body, stair main body's up end is provided with the tread, stair main body's lower terminal surface is provided with the bench bottom plate, the head and the tail of tread, bench bottom plate all are equipped with horizontally overlap joint platform, the top of overlap joint platform is equipped with connects the mounting hole, be equipped with the hoisting point on the tread, stair main body side is equipped with through-hole, stair main body's inside up end and lower terminal surface are pre-buried respectively have honeycomb hole profiled sheet one and honeycomb hole profiled sheet two, honeycomb hole one has evenly been seted up on the honeycomb hole profiled sheet one, honeycomb hole two has evenly been seted up on the honeycomb hole profiled sheet two.
Further, the slope of the stair body is between 20 and 45 degrees.
Further, the whole appearance of the honeycomb hole profiled steel sheet I is matched with the stair tread and the lap joint platform.
Furthermore, the whole appearance of the honeycomb-hole profiled steel sheet II is matched with the stair section bottom plate and the lap joint platform.
Furthermore, the through holes correspond to each step of the step plate.
Compared with the prior art, the invention has the beneficial effects that: this prefabricated staircase adopts honeycomb holes profiled sheet one and honeycomb holes profiled sheet two to replace the upper and lower reinforcing bar of stair, has saved reinforcement's process, the material resources of using manpower sparingly, and honeycomb holes profiled sheet can batch production, improves production efficiency, and the hole that runs through that corresponds each grade flier simultaneously has reduced the stair dead weight, convenient transportation.
