Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a floor slab groove-type pre-embedded component for building curtain walls. Background Technology

[0002] Currently, most building curtain wall systems utilize embedded parts as the basic connection method between curtain wall components and the concrete structure. Embedded channels, in particular, avoid welding, offering significant advantages due to their safety, reliability, ease of construction, and simple maintenance. However, with advancements in the construction industry, building structures are becoming increasingly simplified, resulting in numerous structures without edge beams and with thin floor slabs. This presents challenges for the connection between curtain wall panels and the main structure. Firstly, the thinner floor slabs reduce the tensile strength of embedded parts within the concrete. Secondly, current standards stipulate that the anchorage length of the embedded leg in the concrete under tension cannot be less than 200mm, rendering channel-type embedded parts unusable.

[0003] To address this issue, a common industry practice is to eliminate embedded parts altogether. Instead, the floor slab is drilled through, and bolts are inserted through the concrete, clamped with steel plates at the top and bottom. This prevents the embedded legs of the parts from being stretched within the concrete, allowing the concrete to bear the reaction forces in different directions. The bolts, embedded in the concrete, only bear the material's own stress limit. The quality of this method depends heavily on the quality of the construction process, making quality control challenging. Poor grouting can cause air and water permeability between the upper and lower floor slabs. Uneven hole diameters can cause the bolts to bend, affecting their load-bearing capacity and potentially leading to safety hazards. Utility Model Content
