Embodiment 1

[0051] Such as figure 1 As shown, the prefabricated fully prefabricated staircase disclosed in this embodiment includes a step plate 1, a tread plate 2, a step plate connector 3 and a step plate connector. The step plate 2 is located above the step plate 1 and is connected with the step plate 1 through the step plate connector 3 . Both ends of the stair plate 1 are provided with stair plate connectors, which are used to connect the stair plate 1, the platform plate 5 and the platform beam 6 to coordinate the deformation of the three.

[0052] Such as Figure 1-Figure 3 As shown, the stair slab 1 is a sandwich slab, specifically including a face plate 11 , a bottom plate 12 , a steel bar truss 13 , a filling material 14 and a head steel plate 15 . The filling material 14 is located between the face plate 11 , the bottom plate 12 and the head steel plate 15 . The steel bar truss 13 is anchored to the face plate 11 and the bottom plate 12, and is used for bearing the shear for...

Embodiment 2

[0070] In the present embodiment, the thickness of the stair section plate 1 is 100-500mm, wherein, the steel bar cover thickness of the panel 11 and the base plate 12 is 5-10mm, and the steel bar cover thickness of the common concrete slab is 15mm; the panel 11 and the base plate 12 thickness can be 20mm-30mm, while the minimum thickness of ordinary concrete slabs is 50mm.

[0071] The production process of the stair slab 1 is the same as that of the floor slab, and both adopt one-time molding, which will not be repeated here. The dimensional change of the step slab 1 has low requirements on the formwork, and can be produced with a simple formwork.

[0072] It is worth mentioning that ordinary UHPC can be used as the tread plate 2 as the fair-faced concrete finish, without reinforcement, and the thickness of the plate can be 10-30mm, which can greatly reduce the weight of the tread plate. Of course, the step plate 2 can also adopt decorative UHPC, imitation stone, etc., so a...

Abstract

The invention relates to a fabricated fully-prefabricated stair and a fabricated stair building. The fabricated fully-prefabricated stair comprises stair flight plates, step plates, step plate connecting pieces and stair flight plate connecting pieces, wherein the step plates are located above the stair flight plates and are connected with the stair flight plates through the step plate connecting pieces; the ends of the stair flight plates are connected with the stair flight plate connecting pieces; and the stair flight plates are sandwich flat plates, and face plates and bottom plates of the stair flight plates are made of UHPC (Ultra High Performance Concrete). The fabricated fully-prefabricated stair is integrally formed in a factory, has the characteristics of light weight, high strength, good ductility, good durability, good crack resistance, crack self-repairing, convenience in construction and installation, material saving, high safety redundancy and the like and can be widely applied to various fabricated buildings in industry, civil use and the like. Enough deformation space is formed between the stair flight plates and a main structure of the fabricated stair building, so that damage of external force to the stair and the main structure can be reduced, and the idea of conquering with flexibility is embodied.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an assembled fully prefabricated staircase and an assembled staircase building. Background technique [0002] The prefabricated reinforced concrete staircase is divided into three parts: platform slab, platform beam, and stair section, and the components are prefabricated in the processing plant or construction site, and the prefabricated components are assembled during construction; the prefabricated reinforced concrete staircase has a large weight , The template is complex and the cost is high. For special-shaped stairs with small output, the price is several times the price of cast-in-place stairs. Prefabricated steel structure stairs have high cost, poor fire performance, high maintenance costs in the later period, and regular maintenance is required. How to build a prefabricated staircase that is economical, beautiful, easy to produce and construct has alwa...
