This solution consists of two layers of wooden battens attached to posts fitted with “special” feet that correct any differences in level beneath the structure.
You can combine class 4 pine joists with battens made of exotic wood, for example.
The range of WEASYFIX connectors for wooden posts ensures precise and sturdy positioning.
Advantage 1: A single length of foundation screw is used as the wooden posts compensate for any differences in level.
This makes stock management easier both in the workshop and at the site.
Advantage 2: The finish is more aesthetically pleasing than with metal tubes if you do not intend to mount cladding around the construction.
This solution is achieved in 7 steps:
1. Making holes in the ground
2. Installing foundation screws
3. Installing connectors & wooden posts
4. Installing the bottom structure
5. Installing the top structure
6. Installing the floor
7. Mounting the final construction
It is essential to first make a hole in the ground as this ensures that the screw will penetrate well into the soil.
Lubrication helps to position the foundation screw.
Our portable electric machines, in combination with a laser transmitter and receiver, are used to install the screws in a level position and do not require any specific actions.
“Plate 240” (C40) connectors are attached to the foundation pile, aligned, adjusted vertically and orientated thanks to FIX 3D Connect plates 240 (B20) or Vertikits (D4 as an economical option). The feet of the posts are then attached to the Connect plates 240 (C40).
The bottom wooden structure is fastened to the vertical posts which correct any differences in ground level and raise the structure to the required level.
The wooden top structure is installed cross-wise to make the structure sufficiently rigid.
It is attached at the sides with brackets L60/40.
The final step of this solution consists of installing the floor with the aid of wood screws.
The foundation screws bear the load of the entire construction, therefore their dimensions must be calculated taking into account the loads provided by the French DTU standard.
The foundation screws are positioned in such a way as to allow ventilation under the structure, and the raising components ensure the perfect level.
As the foundation screws bear the load of the entire structure, their dimensions must be calculated taking into account the permanent loads, service loads and weather loading.
The raising components should be reinforced with bracing if necessary to ensure the lateral stability of the entire assembly.
