Curved Glulam Roof Detail

Glulam s major breakthrough came with the so called reichseisenbahnhalle at the world exhibition in brussels in 1910.

Curved glulam roof detail.

Connections are usually made with bolts or plain steel dowels and steel plates. Can manufacture a variety of different types of curved glulams including the standard constant radius curve tudor arches and peak and cambered glulams. Curved glulam is manufactured by bending the laminated boards before they are bonded together with adhesives clamped and cured. While this is true for solid sawn as well as glued laminated glulam timbers the larger sizes and longer spans made possible with glulam components make the proper detailing of connections even more critical.

Optimal roof pitch is 2 12 to 3 12 though other roof pitches are possible. The tension allowed for the glued beams was 136 kg cm2 13 6 n mm2. One of the greatest advantages of glulam is that it can be manufactured in a wide variety of sizes. Can be curved to shape during manufacture.

Glulam uses stress rated seasoned and selected timbers usually radiata pine or douglas fir. Lightweight one sixth the weight of a reinforced concrete beam two thirds the weight of steel. Curved and arched glulams calvert co inc. Our in house engineers and sales personnel can work with you to help realize your architectural visions.

Although the vault roof is curved the individual glulam beams are straight. We can manufacture most custom curved shapes including s curves side curves parabolic arches double compound curves and tight radius curves with a radius as tight as 2 0. Proper connection details are important to the structural performance and serviceability of any timber framed struc ture. Glulam beams optimise the structural values of a renewable resource wood.

Glulam arches with tie rods had the considerable wide span of 43 m. These glulam beams follow the straight roof pitch on their top edge while the bottom forms a radius curve. Glulam beams are readily produced in curved shapes and are available in a range of species and appearance characteristics to meet varied end use requirements. Double curved beams with simpler steel node connections or straight beams with more complex nodes.

Curved headers for porches and towers. F p explored two possibilities. Properties of glulam beams are. The question was really where to put complexity and where to put simplicity rabagliati says.

Pitched and tapered beams taper from the tangent point to a minimum end depth to provide maximum economy. Have strength properties 18 that of normal timber. The cross sections were almost 3 m high and 30 cm wide. Rigidply rafters can design and create curved structural and non structural members for even the most complex members.

Easy to install easy to handle and work on site using hand and power tools plus easy erection.
