CABLE PASS THROUGH SEALING SYSTEMS

摘要

An apparatus for providing a seal around a plurality of elongated members passing through an aperture in a barrier comprises a plurality of support blocks for mounting to the barrier and extending across the aperture, each support block comprising a block body having a back side facing toward the barrier and having at least one interfacial side facing toward an interfacial side of another support block. Each interfacial side comprises a plurality of bearing surfaces and a plurality of passage portions between the bearing surfaces, each bearing surface configured to bear against a corresponding bearing surface on the interfacial surface of the other support block. A sealant portion covers a substantial area of each bearing surface, each of the sealant portions constructed from a compressible sealing material. One or more passage strips constructed from the compressible sealing material extend across each passage portion between two bearing surfaces on either side of the passage portion. A wall seal band on the back side of each block body, constructed from the compressible sealing material, extends from the bearing surface on one lateral side of the block body, around all of the plurality of passage portions, to the bearing surface on the other lateral side of the block body.

1. An apparatus for providing a seal around a plurality of elongated members passing through an aperture in a barrier, the apparatus comprising:
a plurality of support blocks for mounting to the barrier and extending across the aperture, each support block comprising a block body having a back side facing toward the barrier and having at least one interfacial side facing toward an interfacial side of another support block, wherein each interfacial side comprises a plurality of bearing surfaces and a plurality of passage portions between the bearing surfaces, each bearing surface configured to bear against a corresponding bearing surface on the interfacial surface of the other support block; a sealant portion covering a substantial area of each bearing surface, each of the sealant portions constructed from a compressible sealing material; one or more passage strips constructed from the compressible sealing material and extending across each passage portion between two bearing surfaces on either side of the passage portion; and, a wall seal band on the back side of each block body constructed from the compressible sealing material, the wall seal band extending from the bearing surface on one lateral side of the block body, around all of the plurality of passage portions, to the bearing surface on the other lateral side of the block body.
