Anchoring Systems in Wooden Construction
Before assembling the wall elements it is necessary to check that the base plate is of suitable size and with an appropriate leveling of +/-1 cm. To level the base, plastic spacer tiles with a thickness of 2, 3, or 10mm are used. The points where the wall elements will be installed must be waterproofed. The plastic tiles are glued to the base with silicone putty.
The plastic tiles are placed at a distance of 60–70cm, and an expansive cement is applied between the tiles, filling the space between the wall element and the base plate. If the difference in height of the base exceeds 3cm it is necessary to level the base plate.
Reinforced concrete foundation with scaffolding.
For one house, 120–180kg of concrete is usually planned (depending on the size of the house and the flatness of the foundation).
The assembly of the elements of a prefab wooden house is carried out with the aid of a mobile crane. The elements are screwed together with M12×100 mm bolts (corresponding washers 60 mm, thickness 4 mm) and in some cases with wooden screws (SLV 10×160 mm or 10×200 mm depending on the thickness of the wooden frame that we fix) when the interlocking coupling is not possible.
The prefab elements are anchored to the foundation using corner brackets or galvanized ring nails (4 × 60 mm) – 12 galvanized/corner nails, i.e. according to the static calculation, and tension anchors M12×106 mm – as standard 2 anchors/corner or 1 special anchor/angle.
Below we can see some examples.
