Fabricated stair step and construction method thereof

Abstract

The invention provides a fabricated stair step. U-shaped groove reinforcing ribs are fixed to an L-shaped step surface layer, U-shaped grooves in the kicking face U-shaped groove reinforcing ribs andU-shaped grooves in the tread U-shaped groove reinforcing ribs are installed on T-shaped adjusting pieces, the T-shaped adjusting pieces are installed on fixing devices, and the fixing devices are fixed to a tread and a kicking face of an original stair face through first fixing pieces. The invention relates to a construction method of the fabricated stair step. Fabricated dry operation construction is adopted, the kicking face and the tread of the stair step serve as an integral unit component, traditional wet operation construction is replaced, the construction steps are simplified, the construction period is shortened, the engineering quality is improved through factory standardized production, the loss of cement mortar adhesives and other materials is reduced, pollution sources in theconstruction link are reduced, green and environment-friendly construction is achieved, design standardization, production factorization and construction fabrication of the stair step are achieved, and the construction quality and the construction efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to an assembled stair step and a construction method thereof. Background technique [0002] In modern space decoration, special attention is paid to the decoration of stairs. The pavement of traditional stair steps is generally to brush the cement slurry bonding layer on the concrete cushion first, then spread the cement mortar leveling layer, and finally pave the surface layer of steps, which not only belongs to wet construction, but also requires a lot of on-site work and generates a lot of construction waste. It pollutes the environment and has high requirements on the temperature of the construction environment. It is required that the temperature of raw materials and operating environment should not be lower than +5°C, sand with frozen blocks should not be used, and the surface of the plate should not freeze. In addition, the order of surface layer laying is g...

Problems solved by technology

The pavement of traditional stair steps is generally to brush the cement slurry bonding layer on the concrete cushion first, then spread the cement mortar leveling layer, and finally pave the surface layer of steps, which not only belongs to wet construction, but also requires a lot of on-site work and generates a lot of construction waste. Pollution of the environment, and high requirements for the construction environment temperature, the temperature of raw materials and operating environment must not be lower than +5°C, sand with frozen blocks must not be used, and the surface of the plate must not freeze

In addition, the order of surface layer paving is generally from bottom to top, first paste the kick surface, and then pave the tread surface, plus the curing time, the construction period is longer
