Description

Technical Field

[0001] This utility model relates to the field of cable tray installation technology, and in particular to a pre-embedded structure for cable trays penetrating floor slabs in electrical wells. Background Technology

[0002] In building construction, cable trays in electrical shafts need to penetrate floor slabs to form through channels, and these areas are high-risk zones for fire spread. Traditional construction methods typically employ a phased installation approach: after the cable boxes pass directly through pre-drilled holes in the floor slab, expansion bolts are first driven into the outer side of the pre-drilled holes at the bottom of the floor slab to fix the fireproof board, sealing the pre-drilled holes. Then, fireproof packs are filled into the cavity inside the pre-drilled holes, and the top of the fireproof board is finished with fireproof putty.

[0003] However, this operation requires separate steps for fixing the fireproof board at the bottom of the floor slab, filling the top with fireproof packing, and finishing the gap between the inner wall of the reserved hole and the cable box with fireproof sealant. It also requires ensuring that the gap between the cable box and the reserved hole is carefully filled. These multiple steps extend the overall installation period of the cable tray.

[0004] Therefore, how to achieve fireproof design at the point where the cable tray penetrates the floor slab through an integrated pre-embedded structure, and how to enable the rapid installation and fixing of the fireproof layer at the penetration point, has become a technical problem that urgently needs to be solved in this field.
