Abstract (en)
[origin: WO2010140946A1] A space and level adjuster (10) of a floor construction (1), whose joists (4) have vertical drill holes (8), wherein the adjusters comprise screws (11) and joist sleeves (13) with support flanges (19), which abut against a bottom planar surface of the joists (4). According to the invention, the joist sleeve comprises engagements means for fastening the joist sleeve to the joist, said engagement means comprising one or several radial, first protrusions (18), which are formed on the outside (22) of an intermediate portion (47) of the joist sleeve in order to form a stable engagement joint with the joist by penetrating into the wood material, said engagement joint providing a predetermined, axial locking force which is greater than the lift force the joist subjects the engagement joint to due to external loads. Furthermore, the joist sleeve has reinforcement means, which are arranged at the lower end portion (46) of the joist sleeve for reinforcing the connection of the support flange with the sleeve wall (21), said reinforcement means comprising a circumferential, lower extension (20) of the sleeve wall, in an axial direction downward, as seen from the support flange, as well as in a radial direction outward, as seen from the sleeve wall whereby the sleeve wall is thicker at the lower end portion than at the intermediate portion.
