Example Embodiment

[0028] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0029] The invention proposes a fully prefabricated staircase system for fabricated concrete structures.

[0030] Reference Figure 1 to Figure 3 In this preferred embodiment, a fully prefabricated staircase system for fabricated concrete structures includes a prefabricated staircase 1 and a prefabricated ladder beam 2 for installing the prefabricated staircase 1 on the wall, wherein,

[0031] Both ends of the prefabricated ladder beam 2 are reserved with horizontal steel bars 4 to fix it on the wall. The two prefabricated ladder beams 2 respectively support the two ends of a prefabricated staircase 1, and one end of the prefabricated staircase 1 is fixed with a prefabricated ladder beam 2. Hinge support connection, the other end of the prefabricated staircase 1 and another prefabricated ladder beam 2 are connected by...

Abstract

The invention discloses a fully prefabricated staircase system for a prefabricated concrete structure, comprising a prefabricated staircase and a prefabricated ladder beam for installing the prefabricated staircase on a wall, wherein horizontal steel bars are reserved at both ends of the prefabricated ladder beam To fix it on the wall, two prefabricated ladder beams respectively support the two ends of a prefabricated staircase, one end of the prefabricated staircase is connected to a prefabricated staircase beam through a fixed hinge support, and the other end of the prefabricated staircase passes through the other prefabricated staircase beam. The sliding hinge support is connected, and the gap between the two sides of the prefabricated staircase end and the wall is sealed by flexible polystyrene board and fine stone concrete. The fully prefabricated staircase system for the assembled concrete structure proposed by the invention improves the construction efficiency of the staircase.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a fully prefabricated staircase system and a construction method for prefabricated concrete structures. Background technique [0002] At present, the common stair construction methods in construction in progress include traditional cast-in-place structures or prefabricated stair slabs and rest platforms are cast-in-place, and there is no precedent for integral prefabrication of stair slabs and rest platforms. [0003] When using traditional construction methods to construct stairs, the construction speed is slow and the process is complicated. In addition, the construction quality is difficult to guarantee. Furthermore, the construction of decorative surfaces such as plastering on the stairs is required in the later stage, thereby increasing the cost. Contents of the invention [0004] The main purpose of the present invention is to provide a fully prefabricated ...
