\u2728 NIAZIT Joist Installation Guidelines (NIAZIT OWSJ Roof System) \u2728<\/h2>

Installation on Reinforced Concrete Frames<\/h3>

  1. The use of transverse ties (bridging)<\/strong> is mandatory. Each tie consists of two rebars with a minimum diameter of 12 mm: one placed on the bottom chord and one below or on the top chord, parallel to each other and perpendicular to the joists, connected using soft binding wire<\/strong>.<\/p><\/li>

  2. For spans shorter than 3 m, installing temperature reinforcement<\/strong> and tying it to the joist (T\u2011section) is sufficient; transverse ties are not required.<\/p><\/li>

  3. For spans of 3\u20135.5 m, use one row of transverse ties; for spans greater than 5.5 m, use two rows. The spacing between adjacent ties shall not exceed 2.5 m.<\/p><\/li>

  4. Shrinkage and temperature reinforcement<\/strong> shall be installed at 25 cm spacing, perpendicular to the joist direction, using 6, 8, or 10 mm diameter rebars.<\/p><\/li>

  5. When temperature ties are used, they must be kept in tension to prevent protrusion during concreting and to restrain joist movement.<\/p><\/li>

  6. For larger spans in concrete structures, due to compressive forces in fresh concrete, the use of one or two rows of temporary props<\/strong> during concreting is recommended.<\/p><\/li>

  7. The NIAZIT roof system does not require U\u2011bars (odka) or negative moment reinforcement<\/strong>.<\/p><\/li>

  8. NIAZIT joists do not require web concrete<\/strong>; approved blocks may be used adjacent to internal elements.<\/p><\/li><\/ol><\/div><\/div><\/div><\/div><\/div><\/section><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

    Installation on Steel Frames<\/h3>

    1. Transverse ties are mandatory and consist of two rebars (minimum 12 mm) welded to the joists, placed on the bottom and top chords, perpendicular to the joist direction.<\/p><\/li>

    2. For spans less than 3 m, temperature reinforcement welded to the joist (T\u2011section) is sufficient; transverse ties are not required.<\/p><\/li>

    3. Use one row of ties for spans of 3\u20135.5 m and two rows for spans greater than 5.5 m; maximum spacing is 2.5 m.<\/p><\/li>

    4. Shrinkage and temperature reinforcement at 25 cm spacing using 6, 8, or 10 mm rebars. Up to 4.5 m spans, tying with wire is acceptable; for larger spans, welding to the top chord is mandatory<\/strong>.<\/p><\/li>

    5. Temperature ties must be tensioned to prevent displacement during concreting.<\/p><\/li>

    6. No bearing reinforcement or negative moment bars are required in the NIAZIT system.<\/p><\/li>

    7. Web concrete is not required; approved blocks may be used.<\/p><\/li><\/ol><\/div><\/div><\/div><\/div><\/div><\/section><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      Installation on Load\u2011Bearing Walls<\/h3>

      1. Transverse ties (two rebars \u226512 mm) welded perpendicular to the joists are mandatory.<\/p><\/li>

      2. For spans below 3 m, temperature reinforcement welded to the joist (flat bar and T\u2011section) is sufficient; hidden transverse ties are not required.<\/p><\/li>

      3. One row of ties for spans of 3\u20135.5 m and two rows for spans above 5.5 m; spacing \u22642.5 m.<\/p><\/li>

      4. Shrinkage and temperature reinforcement at 25 cm spacing with 6, 8, or 10 mm rebars. Wire tying is sufficient up to 4.5 m; beyond this, welding to the top chord is mandatory<\/strong>.<\/p><\/li>

      5. Temperature ties must be tensioned to prevent movement during concreting.<\/p><\/li>

      6. For spans greater than 5 m, one row of temporary props<\/strong> is essential to prevent joist torsion during concreting.<\/p><\/li>

      7. No bearing or negative moment reinforcement is required.<\/p><\/li>

      8. Web concrete is not required; approved blocks may be used.<\/p><\/li><\/ol><\/div><\/div><\/div><\/div><\/div><\/section><\/section>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
