Special-shaped embedded fittings are pre-installed connection components in building structures, primarily used for the fixed support of non-standard pipelines or equipment. Their core function is to embed metal components during concrete pouring, providing stable connection points for subsequent installations such as doors, windows, curtain walls, and pipelines.
Structural Characteristics
Special-shaped embedded fittings are typically composed of steel plates and anchor ribs, often made of metal (e.g., Q235B steel), with dimensions designed according to equipment load requirements. For example, air conditioner outdoor unit brackets may use 200mm×200mm square embedded parts, while chandelier installations might employ circular embedded parts with diameters of 15mm-20mm.
Application Scenarios
Building Exterior Walls: Curtain wall embedded parts need to withstand external forces such as strong winds and earthquakes, commonly seen in the support structures of high-rise building exteriors.
Roof Engineering: Solar panel brackets often use 150mm×150mm square embedded parts to ensure long-term stable operation.
Ground Equipment: Heavy machinery fixation in industrial plants mostly employs square embedded parts of 300mm×300mm or larger.
Connection Methods
Special-shaped fittings connect to pipelines or equipment through threaded, socket, or flange connections. In some special scenarios, electrofusion welding or clamp-type flexible joints are used to ensure sealing and displacement resistance.
