Smoke curtain T35KD

Constant T35KD smoke curtains are attached to the upper edge to the supporting structure with the help of self -controllers. The support structure must have the required fire resistance class, resulting from the fire resistance class of the building. The attachment takes place with a minimum of two connectors, and the sheets forming the curtain are sewn with self -connectors.

The manufacturer’s technical requirements regarding the mounting elements are presented in detail in the T35KD assembly instructions, with the manufacturer allowing the use of connectors with not worse fire and mechanical properties from the recommended ones.

In the event that the entire curtain has a different shape than a rectangle and when the last fastened sheet cannot be installed in full, it is necessary to cut the sheets. For cutting sheets, use electric scissors with a rotating head. After the installation, it is absolutely cleaned of the surface of filings, screws, etc. In the event of damage to the surface, the necessary (point) retouching should be made as soon as possible, using the appropriate varnish with the original color of the sheet metal. When using a grinder, complaints will not be included.

Note: regardless of the manufacturer’s assembly recommendations for the design of the curtain sheet fastening to the structure and the design of the structure itself, to which the curtain is to be fastened, the designer of the object is responsible. Pruszyński Sp. z o.o. It can be supported by designers in the field of technical consultations for a given project.

In the case of smoke curtains T35KD Pruszyński sheet production, assembly is based on two stages-sewing sheets between each other and fixing sheets to the structure.

COMMENTS

• Smoke curtain support structure should have the required fire resistance resulting from the fire resistance class of the object in which it will be installed
• For installation of smoke curtains, use connectors in accordance with the classification report (report) and assembly instructions (download files). It is allowed to use other connectors with not worse fire and mechanical properties. The designer is responsible for the dates of connectors.

Examples and detailed descriptions of curtain assembly, along with examples of use, can be found in the assembly instructions for T35KD: download files

• DELIVERYConstant T35KD smoke curtains are supplied in the form of rectangular sheets of trapezoidal sheet with an effective width of 1.05m and with a length equal to the designed height of the curtain (maximum 4.50m). Sealing elements made of steel sheet, which are a sealing in a combination of curtain metal with a trapezoidal sheet metal, and self -sight connectors for connecting the curtain panels with each other can also be supplied.
• TRANSPORT

  In the case of receiving its own means of transport, the car should have an open loading platform for free loading and unloading. Galvanized and aluminum sheets must be protected against wetting!

• UNLOADING

  “Manual” unloading should be carried out by the right number of people, i.e. such so as not to move the sheet metal, not bend the side edges and not stretch them. Deformation of sheets during unloading and carrying causes later problems with their proper assembly (gaps on locks, which can cause a curtain leak). The most suitable is unloading in the manufacturer’s packaging using mechanical devices.

• Sheets stored in packages cannot be stored in the open air or in rooms exposed to moisture and variable temperatures. Zinc and alucin coatings, in particular, not yet influenced by weather conditions, and therefore without a protective zone, are sensitive to water condensate with limited air access (sheet plate stored in racer). Particular attention should be paid to unloading in winter conditions and storage in heated warehouses. As a result of a significant temperature difference between the sheets, water precipitates.
• Steps soaked during transport or storage should be dried, then transferring sheets to spacers enabling free air circulation. After drying, galvanized (alucin) sheets should be viewed and covered with a layer of preservative oil.
• Steel sheets intended for longer storage should be viewed and then covered with a layer of machine oil (for galvanized and alucinular sheets), and above all protect against moisture (regarding all sheets).
• he result of not compliance with the above recommendations is the formation of relatively quickly (for galvanized and alucin sheets it can be only a few days) of zinc corrosion – i.e. white, loosely related to the substrate of layers, not consuming corrosion protection.
• Coated sheets in factory packaging should not be stored for more than 3 weeks from the date of production. After this time, the packaging should be cut, and the sheets should be transferred to spacers enabling free air circulation. The maximum storage time should not be longer than 6 months from the date of production under pain of losing the warranty.
• Protective films are used to additionally protect coated sheets against mechanical damage, turns and impacts that can occur during transport, transhipment or profiling. Protective films never release from the obligation to properly protect sheets during storage or against the harmful effects of chemical factors during the processing process. It is recommended to gradually remove the foil from ready profiles, element by element, shortly before the wall and roof elements on the building.
  Incorrect storage method can cause difficulties in removing protective film and leave glue marks on the sheets.
