In the past the roof trusses were both designed and constructed and installed by construction professionals and experts, nowadays the technologies have developedso far that thanks to them, the installation
of roof trusses is facilitated to the maximum, which allows them to be installed also for a person who is not a professional in construction processes but how ?
We, Freimans Timber Constructions, daily manufacture and design roof constructions, placing the installation process in the hands of client, who is responsible for both proper transportation and truss unloading and storage.
The installation of roof trusses is a complicated process only if no instructions are provided by seller. If the instructions and the course of work are provided, then work can be done qualitatively and smoothly also without heavy machinery. The main thing is to know the specifics of roof truss installation, such as the specificity of the timber truss lifting – the roof truss should not be raised behind the top of the truss, which may seem like a complicated task if the crane is not available during the installation process.
However, a great alternative to an automated crane is the mechanical lifting of trusses using a rope system (we recommend that you don’t use thin steel ropes as they can damaged truss).
Tips for installing timber roof trusses:
Roof construction design
Roof constructions are available in different shapes and sizes, so the very first and most important task is to choose, with the help of the designer, the construction roof of the corresponding roof of the building. It can be done by the client on his own if there is basic engineering, but you can also contact us to create a quality and clear roof construction project and find out the exact prices and project calculations.
Timber trusses manufacturing
Once the design work is done, then follows the roof truss development process, which is done accurately according to the chosen shape and size of the roof structure. When the trusses are made, they are arranged according to the result and checked that all connections are appropriate and whether the job is done accurately and will not cause any difficulty in the installation process. We remind you that the process of building roof trusses takes time, so order must be done in a timely manner.
Installation of roof trusses
In rare cases, the trusses from the transportation vehicle are placed immediately on the building, therefore, they must, on the one hand, ensure proper temporary storage on the construction site on a levelled pallet and must be protected from the influence of the environment (rain, wind, change in temperature). As for the installation process, we recommend the use of a crane for the installation of timber trusses, saving both time and labour costs. However, if there isn’t available a lifting crane during the installation of the roof structure, all the initial attention should be directed to a gentle lifting of the truss from the ground without risk or damage roof truss For safety reasons, we recommend that you check the lifting capacity of the crane before starting the work. During the lifting of the truss, the roof truss can not be raised just behind its upper or lower part – if you lift it near the top or bottom, there is a risk that the truss will crack and warp during lifting. The timber truss should be raised above ground so that full support from all sides is provided. If the weight and span of the trusses are small, the timber truss can also be installed manually without the use of a heavy machinery.
Installation of roof trusses with metal connections on wall plate
The key to success in the installation of roof trusses is the placement of trusses adjacent to the wall plate. Compound joints use metal bonding plates, making sure that they are fixed to the wall plate properly, but with care, without damaging the material of the timber truss. At the customer’s request, a scheme is provided with detailed instructions on how and where to fix the metal joining plates.
How to make this process easier ?
We, Freiman Timber Constructions, ensure that numbering of trusses and decoding of numbers will be accomplished on our part, providing you will detailed plan. When making a truss assembly, it is not recommended to make changes to the supplied trusses and connections. Otherwise, such action may not only pose material damage but also endanger the safety of people.
