GLULAM TIMBER ELEMENTS Foreword Hüttemann glulam timber elements (HBE) have established themselves on the market for use as floor, roof and wall elements in solid wood construction, skeleton construction, wood frame construction and in combination with solid stone construction. We have taken what we learned through consultation and discussion with planners and processors since publication of the first edition of "Deckenfibel" and put it into practice in this second edition. We would like to extend our thanks to the specialised wood retailers who gave us the opportunity to present our solid...

Solid and Safe Building Material • Glulam elements satisfy the needs of builders for safe and solid construction methods. Wide Ranging Applications • Glulam elements can be used in solid wood construction, skeleton construction, wood frame construction, in combination with solid stone construction, in industrial construction and for renovations, repairs and alterations. Healthy Room Climate • Glulam elements are vapour-permeable and therefore produce a comfortable room climate (wood can take up moisture and release it again as necessary). Better Physical Building Characteristics • Glulam...

Intermediate Ceilings • It is frequently useful to build intermediate ceilings in commercially used rooms to create storage space. Glulam timber elements are excellently suited for this due to their low unit height. Building Services • In the profiling of glulam elements, it is possible to create grooves in the connection joint into which empty conduit can be laid for electrical installations. Subsequent installation of pipes for electrical lines and supply lines is possible almost anywhere. Simple, System-Based Structural Characteristics •The calculation takes place according to DIN 1052....

GLULAM TIMBER ELEMENTS 15 Glulam elements can be dimensioned according to DIN 4102-4 for the fire protection classes F30-B, F60-B and F90-B. Creation of the element connection joint as double groove - double tongue satisfies the requirements of DIN 41024, Table 61, f for floors to F60-B and Table 70, e for roofs to F60-B. Summer Thermal Protection • Wood has the highest heat storage capability of all typical building materials. This ensures that the heat resulting from solar energy is captured and stored over long periods. Only small amounts of heat are transmitted to the inside. During the...

Glulam timber elements replace rafters, purlins and boarding in the roof area while also featuring much smaller unit heights. Insulation and the sarking membrane are laid without interruption on a flat surface. This has clear advantages for the building's physical properties. Structural Analysis The design loads are determined according to DIN 1055. The following preliminary calculation assumes the following values for dead loads: • Roofing (roof tiles): 0.55 kN/m2 • Insulation (soft wood fibre) t = 16 cm: 0.15 kN/m2 • Glulam element (dead weight = 0.45 kN/m3) 0.30 - 1.20 kN/m2 • Snow load...
