A prefabricated balcony structure and railing

By combining the main unit and base unit of the prefabricated balcony structure, an installation benchmark is provided for the railing. The snap-fit ​​unit engages with the railing, and the side or top rigid connection of the docking unit solves the problem of repeated adjustments required for railing installation, thus improving installation efficiency and stability.

AI Technical Summary

Technical Problem

The existing guardrails require repeated adjustments during installation, which affects stability and has a long installation period, potentially damaging the integrity of the components.

Method used

The prefabricated balcony structure provides an installation benchmark through the cooperation of the main unit and the base unit. The snap-fit ​​unit is used to lock the railing in place, and the butt joint unit is used to rigidly connect the railing from the side or top, forming a double fixation.

Benefits of technology

The installation process has been simplified, repeated fine-tuning has been reduced, installation efficiency has been improved, the stability of the guardrail has been ensured, and the stability loss caused by single-point loosening after long-term use has been avoided.

Abstract

This utility model relates to a prefabricated balcony structure and railing. The prefabricated balcony structure includes a main unit, a base unit, a snap-fit ​​unit, and two docking units. Its advantages are: the main unit and base unit provide an installation benchmark for the railing structure, ensuring basic alignment without repeated fine-tuning, facilitating subsequent installation and fixing; the snap-fit ​​unit engages with the railing structure and base unit via pre-set snap-fit ​​blocks, achieving initial fixing of the railing structure, significantly reducing the cyclical operation of "trial installation-disassembly-re-fixing" in traditional installation, making the installation process simpler and more efficient; the base unit and snap-fit ​​unit work together to restrict the horizontal displacement of the railing structure from the bottom; and the docking units rigidly connect to the railing structure from the side or top, forming a double fixing of "bottom snap-fit ​​+ side or top docking," distributing the stress on the railing structure and preventing stability loss due to single-point loosening after long-term use.
