Characteristics Of Glued Laminated Timber

In this study three layered cross laminated timber clt manufactured from acacia mangium wood panels were developed by using two different types of adhesives namely phenol resorcinol formaldehyde prf and one component polyurethane pur.
Characteristics of glued laminated timber. Glulam can also be produced in curved shapes offering extensive design flexibility. Glulam timber according to din 1052. Many different species of lumber can be used to produce glued laminated timber. A glue laminated timber is an engineered wood product meaning it is made from wood but is machined and assembled to precise specifications to create a predictable dimensionally stable building material.
Glued laminated timber also abbreviated glulam is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable moisture resistant structural adhesives. Glued laminated timber made of beech and hybrid beams made of beech spruce. Glue laminated timber glulam is a structural engineered wood product commonly used for beams and columns in residential and commercial applications. Glulam beams manufactured by apa members are certified with the apa trademark.
Dry lumber and characteristics unique to the glued laminated timber manufactur ing process such as being able to vary the grade of lumber throughout the depth of the member. The aim of this work is to investigate and compare the physical and mechanical properties of clt manufactured using prf and pur adhesives. In north america the material providing the laminations is termed laminating stock or lamstock. Certification of the product an the producer.
Wood is one of the oldest construction materials. Glued laminated timber glulam is composed of several layers of dimensional timber glued together with moisture resistant adhesives creating a large strong structural member that can be used as vertical columns or horizontal beams. It is the basic material in manufacturing glued laminated timber. Cross section structure of glulam.
Such products are used as they are in loadbearing construction and as blanks for various wood products such as window frames laminated logs etc. The apa mark of quality. Laminated timber according to din en 14080 2013. Strength graded and ready finished glued timber.
It is a highly visible form of mass timber in contemporary projects with long spans framing signature designs left exposed to take advantage of wood s natural aesthetic. The functional properties of glulam structures are such that wood as a traditional material allows for new construction challenges and imposes itself as one of the construction materials of the future. The mark signifies that the manufacturer is committed to a rigorous program of quality verification and testing and that products are manufactured in conformance with ansi standard a190 1 standard for wood products structural glued laminated timber.
