RUBNER, LEADER IN EUROPE FOR THE CONSTRUCTION OF LARGE TIMBER BUILDINGS

Rubner Holzbau is the ideal partner to trust when building complex timber structures and projects of high architectural quality. The constant thrust towards innovation and our wide experience gained over decades of work have allowed our company to become the technological leader and specialist in the field of timber.

Rubner Holzbau puts forward innovative solutions for:• glulam constructions• prefabricated roof and wall panels• cross-laminated timber panels or wood-and-

glass curtain wallings • complete building envelopes

This wide range of products has allowed the com-pany to create, all over the world, buildings char-acterised by a common denominator: supreme mastery in the use of timber - a value that is ac-

tively experienced by all our staff at the produc-tion facilities in Bressanone - Brixen, Calitri and Ober-Grafendorf, as also in our design and sales offices all over Europe.

The passion for this raw material also emerges in the many types of projects we develop for public and private residential complexes: • industrial and commercial buildings• sports arenas and shopping centres• churches• congress and cultural centres• bridges • housing estate The yearly production by Rubner Holzbau amounts to 300,000 m2 of prefabricated roof and wall panels in solid wood, and 85,000 m3 of special glulam elements.

A precursor and innovator in the field of eco-sus-tainable material processing, for decades Rubner Holzbau has concentrated its attention on the added value offered by high quality natural prod-ucts. To process wood, a renewable raw material, requires less use of energy with respect to any other material normally used in building and con-tributes, thanks to its absorption of CO2, to protec-tion of the environment and therefore of the hu-man vital space. The extraordinary characteristics of the cellular structure of wood are not altered by the glulam production process, which indeed en-hances and improves the mechanical performance of the material.

More than 50 years have passed since, among the first central European companies, Rubner Holzbau decided to specialise in the production of glulam wood. Glulam by Rubner Holzbau is produced us-

ing conifer strips from the Group sawmills, dried artificially, then glued with parallel fibres in a press, shaped as to specific requests and then finished. Thanks to the production procedure used, this ma-terial has a load capacity up to 80 % higher than that of traditional construction wood. Glulam is particularly well suited to use in construction with a high prefabrication level, but above all in projects with long duration and high aesthetic value.

Thanks to many decades experience gained in design and to the creation of completely auto-matic production lines of high quality standard, it has been possible to reduce the costs of glulam production, allowing for solutions that are both functional and aesthetically pleasing, always within rigid cost parameters.

The market share of glulam structures is in con-stant growth with respect to those of concrete and steel. Glulam has approximately the same load capacity as steel, but far lower weight, al-lowing the construction of wide span structures without heat bridges. Wood boasts a high resist-ance to corrosive atmospheres and offers ex-traordinary characteristics that can answer even to special demands.

Glulam wood has a high fire resistance. The car-bonised layer that forms on the outside due to combustion slows down and can even prevent combustion of the deeper layer of the beams, so that wood structures never collapse sponta-neously. The combustion rate and the structure durability can therefore be calculated.

Seismic risk in central Europe was largely under-valued up to a few years ago. Today however, be-side the specific regulations in each country, we have European regulations on this topic. For roof dimensioning, the horizontal loads that act on the structure of a building due to seismic movement are crucial. The own-weight of glulam, lower than that of solid wood, confers excellent properties on the structure. The experts at Rubner Holzbau analyse all aspects of the real situation as from the design phase, and integrate harmoniously into the project all the possible influencing fac-tors, such as the layout, the construction height, the static and structural characteristics, the sway-brace system, the choice of materials, the distri-bution of the masses and the ductility of the load bearing structure.

The durability of glulam structures – as also of structures built with other materials – depends first on the quality level at the project design and execution stages.

Technical perfection, maximum safety and best quality are the requisites with highest priority for Rubner Holzbau. For this reason all the Rubner Holzbau production facilities have an internal en-gineering office for design and structural calcu-lation of the structures, offering a wide range of services: from dimensioning very simple glulam beams to developing complex roof systems.

The experience acquired by the Rubner Holzbau engineers is all to the customers’ advantage right from the initial consultancy and budgeting phas-es. 60 CAD designers and structural engineers can rely on decades of knowhow, acquired thanks to the many projects completed and to the long experience of expert engineers in the produc-

tion departments. They can therefore guarantee the realisation of solutions that fully respond to the requisites set but also of innovative wood projects - and above all, at limited cost. To reach these objectives it is clearly essential to employ adequate and constantly updated software and hardware devices, and to ensure continuous per-sonnel training.

Glulam Is a natural construction material that can be dimensioned with extreme precision and that, as to structural safety, offers almost unlim-ited possibilities in the creation of structures that optimally combine functional and load-bearing characteristics, without loss of aesthetic harmony. This leads to structures that are slim and elegant, fully answering to structural demands. The engi-neers at Rubner Holzbau also select the structural arrangement that best answers the needs of the single projects.

The quality of all products is guaranteed by ex-ternal controls but also by severe tests carried out in the company laboratories. The humidity of the wood, for example, is checked once a week using the Darr method, while the adherence of the strip joints (finger joints) is checked using a bending test on two samples for each strength class and for each layer. Last, the strength of glued joints is monitored through a delamination test carried out on a sample for every 40 m3 of glulam.

A complex load bearing roof is made up of single components, assembled with steel or wood con-nectors. Rubner Holzbau pays special attention to the correct connection of the structural compo-nents, searching for solutions that take account of all the aspects of structural stability, from aesthet-ics to fire resistance, to durability and to the func-tional characteristics of the project.

Wood connectors are produced by Rubner Holz-bau directly, in its own facilities, while those in steel are made by certified external companies, specialised in steelwork, according to technical drawings by Rubner Holzbau. As to needs, the steel connectors may be subjected to particular treatment. In order to allow a high prefabrication level and a speedy assembly of the components at the building site, the greater part of the connector elements is pre-installed by Rubner Holzbau at its own works, where specific checks are carried out.

Glulam production

21

The Rubner Holzbau glulam beams are in gen-eral produced using Nordic spruce. For special production – above all for outdoor applications – woods such as larch or douglasia (a species of pine) are also used.

The strips for glulam production, cut from fresh roundwood, artificially dried and selected accord-ing to the strength class, are sawn at the Group sawmill and supplied just-in-time to the produc-tion facility. Here they are stacked under vacuum and go on directly to the completely automatic production line. After a quality control system, with elimination of defects (large knots etc) through scanner detection, a continuous beam is produced, in the required length and with fin-ger joints, which is finally planed and glued. The beam produced with this process, of length up to 50 metres, is then shaped to the required form in a numerical control press, respecting the pre-scribed threshold values.

After the phases of hardening and planing, the beam is finished according to customer requests; this is done in large part by numerical control robots that cut the raw beams according to the CAD project. The processing as to customer re-quirements is facilitated by the use of fixed-axis laser drilling and milling units. The consequent detailed control guarantees dimensional preci-sion for the wood elements, which have toleranc-es even smaller than those foreseen for structural steel components. The beams are then painted and impregnated; after that, the steel compo-nents are fitted.

The glulam production at Rubner Holzbau is sub-ject to constant external control by accredited in-ternational agencies, which also check the validity of the national and international certificates and quality marks, as well as the conformity with the prescribed quality standards.

PRODUCTION AUTOMATION AND CONTROL

22

Transport and erection of glulam structures

23

Rubner Holzbau organises the entire logistics process and guarantees, on the basis of a time schedule worked out to the smallest detail, deliv-ery just-in-time to the worksite, even for beams of length 50 and width 4.5 metres. The main advan-tage deriving form this is that the reduced weight of the wood allows a high prefabrication level and hence a reduction in erection times. All the logistics-relevant parameters are analysed at the design stage, discussed with the client and con-sidered in the total cost calculation.

The choice of the means of transport itself de-pends substantially on the shape of the beams, the location of the building site and the available road conditions but also on the size of the beams to be carried, in all cases attempting to find the solution at the same time most ecological and economic.

The erection work is preceded by a series of checks at the production facility; and before work starts at site an Operative Safety Plan (POS) is developed. At site, the components ready for erection are positioned on the relevant supports by means of cranes. The various phases of erec-tion are carried out in conformity with the relevant plans, where the exact position for each wood component, for the metal connectors or for the steelwork is shown. Besides greater speed of erection at site, the high prefabrication level of-fers many economic advantages. It is also possi-ble to schedule with precision all the work to be done and to coordinate exactly the single skills and personnel present at site.
