LIGNA construction system

The construction system for the LIGNA systems timber halls initially foresees two options: Truss girders and solid timber girders. While truss girders are mainly brought to bear – literally – in large halls, smaller halls can be implemented inexpensively and very beautifully with solid timber girders.

LIGNA systems truss girders

Dispensing with large and heavy beams results in a delicate system of upper and lower chord as well as web members, which brings along many advantages in the construction: Despite the low dead weight, a very high static load capacity is achieved, so that even wide-span roof constructions can be lastingly and economically erected. Furthermore, overhead cranes or other technical installations can easily be implemented, and optimum illumination and the use of daylight are also possible.

System construction halls from LIGNA systems with truss girders are particularly suitable for halls with span widths of 20 to 70 metres. The larger the span width, the cheaper the structure becomes in comparison with conventional systems

LIGNA systems solid timber girders

The girders, which are made of solid laminated timber, can be used with spans of up to 25 metres and are cheaper than truss girders due to their standardised dimensions. Thanks to rigid frame corners, fixed columns can be dispensed with in this construction method, as a result of which the foundations are smaller and less complex. The timber structures with solid timber girders are also available as construction kits and are very easy to assemble.

LIGNA systems frames

The high-quality frames are made of aluminium profiles, which are cut to size to suit the respective opening sizes of the specific project. The sophisticated connection system ensures that the frames can be assembled directly on the building site with little effort and fixed in the reveals.

The standard profiles in the colours RAL 7016, RAL 9006 and RAL 9007 have a depth of 145 mm and can be brought to the required depth if necessary by means of widening profiles.

LIGNA systems box gutter

The solid construction of hot-dip galvanised steel with a thickness of three millimetres guarantees lifetime use of the box gutters. In the box gutters there are additional holders for attaching a safety railing so that subsequent work on the roof can be carried out inexpensively and quickly.

LIGNA systems base

The base elements used for the timber halls from LIGNA systems are fastened from the outside to the hall columns and are self-supporting between the foundations. This means that elaborate strip foundations can be dispensed with and the construction preparation costs can be minimised.

The base consists of precast concrete elements with a thickness of 14 to 24 centimetres and a height of 60 to 300 centimetres. As a rule, the base begins approximately 35 centimetres below the finished hall floor and thus guaranteed a clean and solid transition between the exterior and interior of the finished hall. Furthermore, it serves as the formwork for the subsequent hall floor.

Timber as raw material

There is a reason why timber is the oldest building material in the world: timber is stable and can bear heavy loads. Timber halls are durable, retain their structure even in case of fire and can be disassembled quickly if necessary. Furthermore, timber has a pleasant and calming effect in the interior of a commercial, industrial or leisure hall and always provides for a healthy room climate and optimum humidity.

Optimised transport

Short transport routes ensure constant availability and high carbon dioxide savings. In comparison with other building materials, timber is light and can be transported from A to B using simple means.

Simple & fast assembly

The high degree of prefabrication in the factory makes short assembly and construction times possible. High rental and personnel costs for the construction can be avoided with the system construction method from LIGNA systems.
