Embodiment Construction

[0037] In the following, several preferred embodiments of the present invention will be described with reference to the corresponding drawings. In the following description and drawings, the same or similar components are denoted by the same reference numerals, so that repeated descriptions of the same or similar components are omitted.

[0038] Figure 1 to Figure 3 is an exploded perspective view showing a high-strength or ultra-high-strength fiber cement composite prefabricated staircase system 1, 1a and 1b according to a preferred embodiment of the present invention, in which some parts are omitted. Since the basic structures of the prefabricated staircase system are consistent with each other, they will be described simultaneously for the convenience of description.

[0039] The prefabricated stair system 1, 1a or 1b comprises a stair 10 and two inclined stair bases 20 (optionally, an inclined concrete stair base 20 and an inclined iron stair base 21) respectively positio...

Abstract

Disclosed are a stair unit structure, a precast stairway system and a method for constructing such a precast stairway system using one or more stair unit structures. The stair unit structure is formed in a one-piece structure by at least one stair with a riser and a tread. The precast stairway system includes a stairway formed by connecting stair unit structures one after another and two inclined stringers, and has a high or ultra-high strength, but is still excellent in endurance and load carrying capacity due to its relatively superior flexible behavior as compared with an existing high strength concrete. The precast stairway system also exhibits excellent water-tightness and excellent noise-reducing performance as to walking load. In the method for constructing a stairway, one or both stringers may serve as molds in a position where they can be fixed within a wall body to be constructed, thereby forming a floor landing, and an intermediate landing integrally and simultaneously with the wall body. Accordingly, not only the precast stairway can serve as a working passageway, but also the wall body can support the load of one or both inclined stringers in the course of construction, as a result of which labor cost curtailment, construction cost curtailment owing to short construction period, manufacture / transport cost curtailment, and the shortening of construction time can be promoted.

Description

technical field [0001] The invention relates to a prefabricated staircase system and its prefabricated step unit structure, as well as a method for using the prefabricated step unit structure to construct the prefabricated staircase system. Specifically, the present invention relates to a high-strength or ultra-high-strength fiber-reinforced cement composite material prefabricated staircase system (its strength ranges from 60 to 200 MPa, and it has relatively excellent flexibility characteristics, and has good water tightness and durability), and a prefabricated step unit structure for assembling such a prefabricated stair system, and a method of cost-effectively constructing a prefabricated stair system while ensuring that said stair system has good structural quality. Background technique [0002] Usually, vertical moving lines in buildings, especially high-rise buildings, are connected by installing elevator and stair systems. However, when building this staircase, the w...
