  • Patent number: 7836645
    Abstract: Devices are provided for protecting pipe ends at a construction site on which concrete will be poured from being moved out of position or damaged during construction or from injuring workers. The devices have an upper frame and an enclosure adapted to fit together to form a rigid, generally rectangular-shaped body having a recess into which the pipe ends to be protected extend when the body is positioned in place. The body, dimensionally configured to fit between frame studs that will installed later in construction, has fastening tabs for securement to a base on which concrete will be poured. After the concrete has set, the body—partially embedded in the concrete—provides tradesmen access to the pipe ends within via an open top. Methods are also disclosed for protecting exposed pipe ends utilizing the inventive devices.

  • Patent number: 7464507
    Abstract: Devices and methods are provided for protecting pipe ends that project upwardly during building construction and for reducing the safety hazard posed by such pipe ends. The devices include a rigid body suitable for positioning on a base on which concrete will be poured, having two opposed end walls, two opposed side walls, a recess therebetween, a top end, a bottom end, and a lateral tab extending from at least one end wall. A shield is securable to at least one side wall for protecting the pipe ends during later construction. In two embodiments, a plate positioned at the bottom end has an opening dimensionally and spatially configured to correspond to each pipe end requiring protection.
