A method for levelling an anchoring system for a dropped ceiling, a floating floor, a pipe or a cable tray, having at least one support bracket for the pipe or a section bar of a support frame of a dropped ceiling, a floating floor or a cable tray, and an adjustment screw to adjust the distance of the section bar from a reference surface, wherein a laser receiver is placed in contact with the section bar or the support bracket, has an optical window to receive a laser beam emitted by a laser level, assumes two height states indicating the receiving position of the laser beam relative to a reference position, and transmits, in a wireless manner, two control signals corresponding to the two height states, and wherein an electric screwdriver receives, in a wireless manner, the control signals and switches the rotation of the adjustment screw between one direction and the opposite direction based on the control signal received.

A tile aligning and leveling system that uses an under tile base re-usable upright connecting tab, which is detachably connected to said under tile base, a re-usable flexible edge slotted cap configured to slip over the connecting tab and latch thereto as the cap is slid further down the connecting tab. The cap has an edge slot so that the connecting tab can be separated from the cap, by merely sliding the cap, so that the connecting tab passes through the slot. A flexible spring-like portion of the cap provides increased force on the tile even if undesired elongation of the connecting tab occurs.

A construction jig is disclosed for facilitating appropriate notched cuts in vertical posts used for deck or post and beam construction applications. The jig is a multi-sided jig adapted to be either slipped over or slipped around a vertical post commonly used in such constructions. A crossmember for the construction is held by the jig and the jig is moved up and down until the crossmember is level. A saw is then guided by the jig to make an appropriately level notch in the vertical post, as required by building codes. An optional handle is useful, and it may extend outwardly from a side of the construction jig, which is adapted for movable and removable placing of the multi-sided jig over the vertical post to indicate level placement for the deck crossmember.

A method and assembly for laying and leveling adjacent tiles. The assembly includes a base member having a bottom plate and a cam tool. The cam tool is pivotally combined with the base member so that the cam tool rotates relative to the base member about an axis of rotation. The cam tool has a handle combined with a cam member. The cam member has a tile engaging surface around its outer periphery with a first portion that is a first distance from the axis of rotation and a second portion that is a second distance from the axis of rotation. Rotation of the cam tool around the axis of rotation causes the distance between the tile engaging surface and the bottom plate to change. One or more tiles is adapted to be placed between the tile engaging surface of the cam member and the bottom plate of the base member. The tiles are compressed between the tile engaging surface and the bottom plate as the cam tool is rotated to a desired position.
