With the development of modern industrial technology, the assembly type building gradually replaces a common building system in the prior art with the advantages of high construction speed, small restriction by climate conditions, labor saving and the like, and the stairs used in the assembly type building are also prefabricated and then hoisted. The general stair is of a solid concrete structure, and is heavy in weight, high in manufacturing cost and difficult to hoist.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problem of large dead weight of an assembled stair in the prior art, and provides a prefabricated composite light multi-ribbed sandwich stair.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a prefabricated compound light close rib sandwich stair, includes the bottom plate, a plurality of platform of marking time that are located the bottom plate upper end and the end plate that is located the bottom plate and marks time platform both ends, wherein the end plate is used for being connected with the main part building. And a longitudinal rib beam, a transverse rib beam and a light filling block are arranged between the bottom plate and the stepping platform, and the light filling block is clamped in a cavity formed by the stepping platform, the bottom plate, the longitudinal rib beam and the transverse rib beam.
Preferably, the bottom plate is made of glass fiber grid reinforced concrete thin plates, so that the structural strength of the stair is guaranteed, and the dead weight of the plate body can be greatly reduced.
Preferably, the stepping platform, the longitudinal rib beam and the transverse rib beam are made of lightweight aggregate structural concrete with the strength of more than 20Mpa, and the stepping platform, the longitudinal rib beam and the transverse rib beam are light in weight and high in support strength.
Preferably, the volume weight of the light filling block is less than 10kg/m3The polystyrene foam board reduces the weight of the stair.
Furthermore, the through holes transversely extending are formed in the step platform, so that the weight of the stair can be further reduced, and the step platform can be used as a hoisting hole to facilitate hoisting of the stair.
Preferably, the light filling blocks are arranged inside the end plates, so that the overall weight of the stair is reduced.
Compared with the prior art, the utility model has the beneficial effects that: the bottom plate of the prefabricated composite light dense rib sandwich stair is made of glass fiber grid reinforced concrete thin plates, the stepping platform, the longitudinal rib beams and the transverse rib beams are made of light aggregate structural concrete with the strength larger than 20Mpa, and the light filling blocks are foam plates, so that the stair is light in self weight, large in structural strength, low in manufacturing cost and capable of saving transportation consumption.

In this embodiment, the material of bottom plate 1 is glass fibre net reinforcing concrete sheet metal, guarantees stair structural strength, and can alleviate the plate body dead weight greatly.
In this embodiment, the stepping platform 2, the longitudinal rib beams 3 and the transverse rib beams 4 are made of lightweight aggregate structural concrete with strength greater than 20Mpa, and are light in weight and high in support strength.
In this embodiment, the lightweight filling block 5 has a volume weight of less than 10kg/m3The polystyrene foam board reduces the weight of the stair.
Further, the through hole 7 that transversely extends is arranged in the platform 2 of marking time, can further lighten the weight of stair, and can regard as the hoist and mount hole, makes things convenient for the hoist and mount of stair.
In this embodiment, the light filling blocks 5 are arranged inside the end plates 6, so that the overall weight of the staircase is reduced.
The bottom plate 1 of the prefabricated composite light multi-ribbed sandwich stair in the embodiment is made of glass fiber grid reinforced concrete thin plates, the stepping platform 2, the longitudinal rib beams 3 and the transverse rib beams are made of light aggregate structural concrete with the strength of more than 20Mpa, and the light filling blocks 5 are foam plates, so that the stair is light in self weight, large in structural strength, low in manufacturing cost and capable of greatly saving carrying consumption.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
