Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a wooden structure embedded part for a double-layer fair-faced concrete sloping roof. Background Technology

[0002] In traditional building construction, sloping roof structures require precise connections between timber components and concrete through embedded parts. While embedded parts provide necessary structural support, they often leave exposed after construction, affecting aesthetics and necessitating additional decorative ceilings to compensate. However, fair-faced concrete sloping roofs are decorative components, with the finished surface being the final decorative surface. For buildings requiring timber structures suspended beneath fair-faced concrete sloping roofs for decoration, the positioning and surface flatness of embedded parts are extremely critical. All embedded parts must be completely embedded within the concrete to ensure the integrity and aesthetics of the visible surface. Furthermore, the installation of lighting fixtures is also a significant decorative requirement for timber structures. Traditional lighting installation methods often require drilling holes in the timber structure or directly exposing wiring, which not only damages the aesthetics but also negatively impacts the durability of the timber structure.

[0003] Therefore, it is necessary to explore an embedded part that can meet both structural requirements and decorative requirements of fair-faced concrete sloping roofs, so that the embedded part can be completely embedded in the concrete to achieve the integrity and aesthetics of the visible surface, while also meeting the wiring requirements for installing lighting fixtures.
