In the monumental restoration of buildings subject to supervision, the material principle of preservation of the existing structure without the use of concrete is often imposed. To this end, the wood-wood intervention is the only possible solution. Al-fer has designed the self-levelling connector with a single 16 mm diameter piece suitably machined to ensure the best seal between the materials and to facilitate their installation.The inertia is increased by reducing the weight to a minimum, in fact the structural loads represent only a 25% share compared to the wood-concrete solution. This solution is optimal especially from the seismic point of view where a lower plane mass corresponds to a reduced inertial force.The particular conical thread with reverse fit together with the washer in the head induce a sort of vertical pre-compression between the contact materials with consequent reduction of the horizontal slides and therefore of the vertical deformations
Installation
Installation is simple does not require a specialised worker:
pre-drill with 11.5 mm tip diameter up to the maximum depth;
The hole is widened with a 16 mm diameter tip just beyond the existing planking;
Connector fastened by means of a thrust screwdriver (min 280 Nm ) until the first head is completely penetrated into the wood and the upper part is Self-Shearing
The limit stop and washer mechanically compress the new wooden beam against the floor board and therefore the existing wooden beam thus improving the effectiveness of the connection.
Connectors distance
For connector installation, it is best to follow the instructions provided by the work director, who can use the free program that can be downloaded under the item Software or request technical assistance.
