    Hilti HIT-HY 270 mortar meets the conditions stipulated by TRAV (Technical Regulations for the Use of Safety Barrier Glazing)Thanks to its highly esthetic appearance and architectural possi-bilities, glass is becoming increasingly important as a supporting structure material. Large, inspiring facades, interior walls and other glass elements reflect our contemporary times and are now standard in many structures.

    SAFETY BARRIER GLAZING AND GLASS RAILINGS

    Application:

    Safety barrier glazing through linear attachment of glass railings in U-profiles. Loads are securely transferred through the glass elements via the Hilti HIT-HY 270 mortar in the U-profiles.

    Hilti HIT-HY 270 creates a strong, reliable and flexible fastening solution capable of withstanding the high static and impact load requirements. The composite mortar has a National Test Certificate in accordance with the Technical Regulations for the Use of Safety Barrier Glazing (TRAV), an external evaluation and an inspection report.

    Hilti HIT-HY 270 offers maximum application flexibility even for fastenings with an incline of up to 30, such as glass railings on stairs. Glass elements can be removed and replaced with ease due to its chemical/mechanical properties.

    Advantages:

    Secure and play-free fastening Mortar durability with European

    Technical Approval Maximum application flexibility Chemical and mechanical compati-

    bility Capable of withstanding environmen-

    tal conditions

    Hilti has been a reliable partner in glass construction applications for more than 20 years and has many years of experience in a wide variety of large-scale projects: schools, shopping centers, museums and administrative buildings. The laminated safety glass with linear supports developed by Hilti Deutschland AG is used in accordance with Category B of the Tech-nical Rules for the Use of Safety Barrier Glazing (TRAV). The mortar's high level of compressive strength and outstanding ductility properties at the same time translate into secure load trans-fer without any tension peaks.

    Thickness of toughened safety glass: min. 10 mm, max. 19 mm. The intermediate layer must always be at least 1.52 mm.

    The glazing's safety barrier function was tested in accordance with Section 6 of the Technical Regulations for the Use of Safety Barrier Glazing (TRAV), while the evidence of load-bear-ing capacity under impact loading was tested by means of pendulum impact tests.

    The glass panes are provided with linear support along the bottom edge in a bed of Hilti HIT-HY 270. During the application, the following must be observed: The glass pane's clamping depth must be at least 100 mm Tare weight transferred through suitable glass wedge Evidence of the steel sub-construction under static impact Top bedding protected by a suitable seal Top edge of the pane connected to an attached and conti-

    nuous handrail profile Glass pane has linear support; two strips measuring at

    least 20 mm tall

    Validity

    National Test Certificate no. P2014 - 3041 is valid for the construction type described therein. Please refer to the fol-lowing table for the limit dimensions of panes which can be embedded using Hilti HIT-HY 270.

    Measurement

    For the application case, mathematical evidence of the load-bearing capacity under static impact on glazing and the support structure must be provided in accordance with Section 5 of the Technical Regulations for the Use of Safety Barrier Glazing (TRAV).

    Comment:The application also complies with the new DIN 18008 Part 4 standard.

    Test

    The glazing's safety barrier function was tested in accor-dance with Section 6 of the Technical Regulations for the Use of Safety Barrier Glazing (TRAV). The evidence of load-bear-ing capacity under impact loading was tested by means of pendulum impact tests. ((Source: National Test Certificate, page 5))

    Processing instruction for Hilti HIT-HY 270 mortar for safety barrier glazing Comment: This processing instruction complies with the TRAV and the Technical Regulations for the Use of Glazing with Linear Support (TRLV), as well as the National Test Certificate P2014 - 3041 from the Laboratory for Steel and Lightweight Metal Constructions at Munich University of Applied Sciences and the inspection report in accordance with the TRAV.

    1. Handrail structure and clarification before execution: Practical tip

    When designing the railing, ensure that there is a suitable distance between the glass and the U-profile so that fill-ing can take place with the sprayer and/or the sprayer extension.

    TRLV Technical Regulations for the Use of Glazing with Linear Support

    2. Materials required for execution: Practical tip Hilti injection materials:

    Hilti HIT-HY 270 mortar HDM manual dispenser or HDE elec-

    tronic dispenser If necessary: additional sprayer and

    sprayer extension (10 x 1 m)

    Standard auxiliary materials in glass constructions (no Hilti products): Suitable glass wedge Suitable chocks PE round cord Suitable film for covering, if necessary Suitable sealing compound, if nec.

    Use a 500 ml film pack with a HDE 500 A dispenser for greater productivity and enhanced working comfort.

    Use a sprayer extension longer than 100 mm to improve working ergonomics.

    3. Alignment of the glass handrail: Practical tip Insert a suitable, clean glass wedge (7)

    according to standard practice Adjust the glass pane (2) as stated in

    the technical specification and/or in accordance with the Technical Regulations for the Use of Safety Barrier Glazing (TRAV)

    Avoid contact between the glass and the U-profile

    Coat the pane with a dark film in the clamping area to filter through the bright mortar.

    If and when using foil such as this, check that it is compatible with the mortar prior to the application (see page 3)

    Align the glass pane and fix it with chocks (8)

    Position the chocks at the lateral edges of the glass. This ensures that the holes created by the chocks are easier to close once the chocks have been removed.

    The gap between successive glass panes (2) should be sealed with two vertically positioned round cords (9) so as to break up the layer of mortar

    (8) Chocks

    If there is no mortar between the panes, it makes it easier to remove individual glass elements if glass is damaged.
