Abstract

The subject of the application is a fireproof connector for general construction installation passages, which is a flammable pipe or a non-flammable pipe (1b) with a flammable synthetic foam insulation (2) applied to the pipe and a fireproof band (3), wound and fixed permanently on the flammable pipe or a non-flammable pipe (1b) with a flammable synthetic foam insulation (2) applied to the pipe. The band (3) is fixed permanently on the flammable pipe or the non-flammable pipe (1b) with the flammable synthetic foam insulation (2) applied to the pipe, by means of a foil (4). The band (3) can also be fixed permanently on the combustible tube or the non-combustible tube (1b) with the combustible synthetic foam insulation (2) applied to the tube by means of an adhesive.

Description

Pattern description

The subject of the utility model is a fireproof connector for general construction installation passages, especially for installation inside fireproof partitions.

During the assembly of general construction penetrations through walls or ceilings through which flammable pipes and non-flammable pipes insulated with flammable synthetic insulating foam pass, it is required to make fireproof sealing of these installation penetrations.

A Carboline intumescent band is known, made of a mixture of polymers and fillers that cause the band to swell under fire conditions. In order to make a fireproof seal in the installation passage, the fireproof band should be unwrapped from the drum and cut to the required length, and then wrapped around the pipe or insulation made of insulating foam, the number of wraps and the total thickness of the tapes must be strictly defined and in accordance with the standard ETA 15/0511. This is a great inconvenience, because people who perform such general construction transitions must always use the ETA 15/0511 standard in order to precisely wind the band. In order to eliminate this inconvenience, a fireproof connector solution was developed, designed for installation inside fireproof partitions with an identifiable defined partition thickness, stiffness and density. The fireproof connector according to the utility model is characterized by the fact that it is a flammable or non-flammable pipe with a flammable synthetic foam insulation applied on the pipe and a fireproof band, wound and fixed permanently on the flammable pipe or non-flammable pipe with a synthetic foam insulation flammable on the pipe . The fireproof band is fixed permanently with a foil, which protects the band against unwinding or sliding. The fire retardant band can also be permanently attached to a combustible pipe or a non-combustible pipe with a combustible synthetic foam insulation applied to the pipe by means of an adhesive.

The object of the utility model is shown in the drawing, in which Fig. 1 shows a cross-section of a fireproof connector made of a combustible pipe, and Fig. 2 shows a cross-section of a fireproof connector made of a non-combustible pipe with a combustible synthetic foam insulation applied to the pipe. The fireproof connector is a flammable pipe 1a or a non-flammable pipe 1b with combustible insulation made of synthetic foam 2 and a fireproof band 3, wound on and permanently fixed on the flammable pipe 1a or non-flammable pipe 1b with a flammable insulation made of synthetic foam applied on the pipe 2. Fireproof band 3 it is permanently attached to the connector through a foil 4 which may be sleeve-shaped or a bandage wrapped twice around the perimeter of the connector. The foil 4 has overprints identifying the product, its dimensions, El fire resistance class, and CE mark. The foil 4 can be made of plastic or constitute an electrical clamp.

The fire-resistant band 3 can also be fixed permanently on the combustible tube 1a or on the non-combustible tube 1b with the combustible synthetic foam insulation 2 applied to the tube by means of an adhesive.
