Therefore, the industrial preparation of the building industrial assembled prefabricated staircase conforms to the concept of building industrialization, and has the characteristics of uniform production, convenient transportation and hoisting, construction speed acceleration, construction precision improvement and resource consumption reduction.
The assembled integral stairway occupies an important position in the house industrialization, and due to the fact that the sizes of the stairways are well unified, a good opportunity is provided for large-area application of the prefabricated assembled integral stairway. The prefabricated integral stair is constructed in China, and the prefabricated integral stair is constructed in China at first, steel bars are embedded in cast-in-place beams in general, holes are reserved in prefabricated step plates, the reserved steel bars are sleeved in the reserved holes when the step plates are installed, the reserved holes are cast after fine stone concrete with the height higher than that of the step plates by one grade, and the prefabricated stair is installed. The prefabricated assembled integral stairway is mainly applied to the double-running stairway, and is applied to the scissors stairway less. Meanwhile, in the domestic application projects, the tower crane with larger hoisting capacity is required to be installed for hoisting the prefabricated part, and the cost of the tower crane is about 30 percent higher than that of the conventional project.
Therefore, in order to solve the above problems, it is necessary to provide a segmented prefabricated scissor type stair, which overcomes the above drawbacks of the prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a prefabricated scissors formula board-like stair of segmentation has solved the overweight problem of full prefabricated stair hoist and mount.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
the utility model provides a prefabricated scissors formula plate stair structure of segmentation, including prefabricated platform roof beam, bench board, overhanging landing slab, wherein overhanging landing slab divide into overhanging landing slab and lower overhanging landing slab, its characterized in that: fixing a prefabricated platform beam on a shear wall, then respectively lapping prefabricated upper and lower overhanging platform plates on the platform beam, sleeving the prefabricated platform beam with a steel bar through a reserved hole, later casting a reserved hole by using high-grade fine aggregate concrete, lapping the prefabricated bench plate on the upper and lower overhanging platform plates, sleeving the steel bar in the reserved hole, finally casting the reserved hole, and adopting the same process for construction of the stair on the other side to finally form the segmented prefabricated scissor type plate type stair structure.
Further, go up overhanging landing slab, be provided with two sets of nails that hang respectively on the ladder of overhanging landing slab and bench board down, make things convenient for the tower crane to install.
Furthermore, the steps of the upper overhanging platform plate, the lower overhanging platform plate and the ladder section plate are composed of ladders with right-angled triangles in cross section, and the triangular step plates are perforated in order to reduce the dead weight.
The utility model has the advantages and the beneficial effects that:
1. the utility model provides a pair of prefabricated scissors formula board-like stair structure of segmentation, the integral stair of assembly divide into the three-section, and every section can adopt conventional tower crane to hoist and mount, has solved and has assembled the problem that the integral stair of assembly adopted the tower crane or the crane of large-tonnage to install usually in the past, reduces installation cost.
2. The utility model provides a pair of prefabricated scissors formula board-like stair structure of segmentation, industrialization degree is higher, and the stair is whole for mill's preparation, field installation, and the stair shaping is of high quality, reduction in production cost, and it is convenient to transport, environmental protection economy.
