摘要： A hand-held concrete edger is formed with a rectangular blade having a first, substantially planar part with an upper surface and a lower surface, and a second part extending substantially at a right angle from a long side of the first, substantially planar part, away from the lower surface. A handle extends substantially perpendicularly away from the upper surface of the first, substantially planar part and is configured with a spray device including a water supply and a sprayer, for spraying water onto an advance path of the edger. A control and vibration module is arranged on the upper surface of the substantially planar part and configured with a vibration element that vibrates the rectangular blade.

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 rotating cylinder cement screeding system having a drive assembly and handle at one end for powering and controlling the screeding system. The rotating cylinder may be defined by one or more tubular screed roller sections of varying lengths, thereby allowing a user to customize the length of the system to match a specific cement pour. Further, each tubular screed roller section may be supplied with a male and female end for interlocking with each other and for receiving a variety of add-on attachments. At least one riser assembly may be interconnected to a drive assembly end and/or a non-driven end of the rotating cylinder cement screeding system. The riser assembly may elevate the rotating cylinder a distance above a finished slab to prevent the rotating cylinder from contacting the finished slab during a screeding operation.

摘要： The assembly for leveling new concrete includes a driver that has a guide that is placed in a mounting structure so that the driver may be used to drive the mounting structure into the ground. The driver has both a removable rebar marker and conduit marker so that depending on whether an individual wants to use a screed pipe conduit or rebar as a support structure in their concrete the support structures are properly aligned.

摘要： A lightweight, powered screed machine for screeding the surface of a quantity of concrete having a pair of rails extending to either side, includes a frame having a handle arrangement, for manual engagement by an operator, and an elongated screed blade extending between the support rails. The machine further includes a powered vibration mechanism mounted on the frame. A pair of posts or masts are provided with one of the pair of posts attached to the frame adjacent each end of the blade and extending upward. Each of a pair of supports is positioned adjacent an associated end of the blade. Each support has rollers for engaging and riding on one of the pair of support rails, and each of the supports is attached to the frame so as to support the frame over the concrete. Each of the supports includes a linear actuator for raising and lowering the frame adjacent the rail. A pair of laser receivers is provided with each of the pair of laser receivers mounted on an associated one of the pair of posts. A control controls the linear actuators such that the screed blade is maintained at a desired height as the screed blade is moved over the concrete.
摘要翻译： 一种用于熨平一定数量混凝土表面的轻型动力熨平板机，其具有延伸到任一侧的一对导轨，包括具有手柄装置的框架，用于由操作者手动接合，以及在支撑轨道之间延伸的细长的刮板叶片 。 该机器还包括安装在框架上的动力振动机构。 一对柱或桅杆设置有与刀片相邻并且向上延伸的一对柱中的一个柱。 一对支撑件中的每一个定位成与叶片的相关联的端部相邻。 每个支撑件具有用于接合和骑在一对支撑轨道中的一个上的滚子，并且每个支撑件附接到框架以便将框架支撑在混凝土上。 每个支撑件包括用于升高和降低邻近轨道的框架的线性致动器。 一对激光接收器设置有一对激光接收器中的每一个安装在一对相关联的一个柱中。 控制器控制线性致动器，使得当熨平板叶片移动到混凝土上时，熨平板叶片保持在期望的高度。
