摘要： A concrete float, float assembly, float adapter and interface, and vibration apparatus and methods are described. A vibration assembly has at least first and second interface components, and for example one interface component can join with an interface component on a pivot assembly and another interface component can join with an interface component on a finishing tool. An interface such as may be included in a quick attach/release configuration may be integrated on vibration apparatus and/or on a pivot assembly for quick attach/release of a joining component. A vibration assembly may include a load transmission or transfer component for transferring a load through the vibration assembly. A pivot assembly may include first and second interface components.

摘要： A concrete finishing assembly includes a plurality of rails that each has a guide surface. A plurality of couplers each releasably engages a respective pair of the rails for attaching the respective pair of rails together. In this way the plurality of rails defines a border to surround a shower floor. A cylinder is provided and the cylinder can be inserted into a drain in the shower floor. A trowel unit is provided that has an adjustable length and the trowel unit is attachable to the cylinder. The trowel unit is slidable along the guide surface of the plurality of rails that defines the border. In this way the trowel unit can smooth concrete on the shower floor at a predetermined slope for draining water into the drain.

摘要： A system and method for providing a level flooring surface includes a plurality of groups of leveling blocks, wherein each of the plurality of groups has a defined height different from the others of the plurality of groups of leveling blocks and a defined color different from the others of the plurality of groups of leveling blocks. Each of the leveling blocks has an adhesive layer so that the leveling blocks can be fixed to a surface. The leveling blocks are selectively adhered to a surface in a grid-like pattern so that upper surfaces of each of the leveling blocks are substantially planar with a pre-identified zero-level elevation so that a level flooring surface can be installed based on visual confirmation of elevation levels along the grid-like pattern.

摘要： Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and lateral support bars for attaching a screed bar to the cross support bar. The screed bar is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.

摘要： A method including placing a screed hardware unit upright on a surface. The hardware unit includes a base and a post. The base is fastened on the surface such that the post extends vertically from the base. The method further includes adjusting a height of the hardware unit so as to be consistent with a desired grade. Concrete is poured up to and/or around the hardware unit, and the concrete is screeded at the grade indicated by the height of the hardware unit.

摘要： A system for finishing a prefabricated wall panel includes a rack wall, three tracks, and a roller. The rack wall includes columns that can insert into molds in the prefabricated wall panel. The columns are rotatable from a vertical position to a horizontal position. Two lateral tracks each include a channel and bolts along a length of the track. The two lateral tracks are mounted to two ends of the wall rack and spaced apart about the width of the prefabricated wall panel. A top track includes bolts along a length of the track. The top track is located parallel to the wall rack at a distance about the height of the prefabricated wall panel. The roller has wheels that travel in the channels of the two lateral tracks so the roller is can roll over mortar on the surface of the prefabricated wall panel.
