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. The method comprises: (a) positioning a device in accordance with the invention on the base so the pipe ends project into the recess and the body forms a barrier between the pipe ends and the concrete slab to be formed; (b) securing the device to the base by inserting a securing structure through each lateral tab; and (d) after the concrete layer has been formed, removing any securing structure from above the surface of the concrete to continue with the construction of the building. ## Claims ### Claim 1 A pipe protector for protecting upwardly projecting pipe ends at a building construction site, the pipe protector comprising: a rigid body for securing to a base on which a concrete slab will be formed that has at least one pipe end to be protected; the body having a completely open bottom end, an open top end, two opposed side walls and two opposed end walls defining a recess between the bottom end and the open top end, and a lateral tab extending from each end wall, the lateral tabs extend into a different but parallel plane with respect to each other to allow the pipe protector to be secured to another serially adjacent pipe protector; the body being suitable for positioning on the base so the bottom end contacts the base and the body surrounds the pipe ends, forming a barrier between an area surrounding the pipe ends and the base external to the body on which the concrete will be poured such that after the concrete slab is formed, a portion of the body extends above the concrete and the open top provides access to the pipe ends within the recess. ### Claim 2 (depends on 1) The pipe protector of claim 1 wherein the body is dimensionally configured to fit between frame studs in a building under construction. ### Claim 3 (depends on 1) The pipe protector of claim 1 wherein the body further comprises a level indicator for setting the depth of the concrete, disposed on at least one wall selected from the side walls and the end walls at a vertical distance from the bottom end corresponding with the surface of the concrete to be poured outside the body. ### Claim 4 (depends on 3) The pipe protector of claim 3 wherein the level indicator comprises a flange extending outwardly from the body. ### Claim 5 (depends on 1) The pipe protector of claim 1 further comprising a cover removably attachable at the top end for preventing concrete from entering the recess through the top end. ### Claim 6 (depends on 1) The pipe protector of claim 1 wherein the body is formed of a rigid plastic. ### Claim 7 (depends on 6) The pipe protector of claim 6 wherein the body is a unitary piece molded of rigid plastic. ### Claim 8 (depends on 1) The pipe protector of claim 1 wherein each lateral tab has an aperture adapted to receive a securing structure therethrough for securing the pipe protector to the base. ### Claim 9 (depends on 1) The pipe protector of claim 1 wherein each lateral tab is disposed on the end wall between the bottom end and an elevation from the bottom end corresponding with the surface of the concrete to be poured. ### Claim 10 A pipe protector comprising; a rigid body for securing to a base on which a concrete slab will be formed that has at least one pipe end to be protected; the body having an open bottom end, an open top end, two opposed side walls and two opposed end walls defining a recess between the bottom end and the open top end, a shield securable to the top edge of at least one of the side walls for further protecting the at least one pipe end in the recess, and a lateral tab extending from each end wall, the lateral tabs extend into a different but parallel plane with respect to each other to allow the pipe protector to be secured to another serially adjacent pipe protector; the body being suitable for positioning on the base so the bottom end contacts the base and the body surrounds the pipe ends, forming a barrier between an area surrounding the pipe ends and the base external to the body on which the concrete will be poured such that after the concrete slab is formed, a portion of the body extends above the concrete and the open top provides access to the pipe ends within the recess. ### Claim 11 A pipe protector comprising; a rigid body for securing to a base on which a concrete slab will be formed that has at least one pipe end to be protected; the body having an open bottom end, an open top end, two opposed side walls and two opposed end walls defining a recess between the bottom end and the open top end, a lateral tab extending from each end wall, the lateral tabs extend into a different but parallel plane with respect to each other to allow the pipe protector to be secured to another serially adjacent pipe protector, and a plate, disposed in the recess and over the open bottom end, having an opening that corresponds dimensionally and spatially to each pipe end for fitting the pipe end therethrough; the body being suitable for positioning on the base so the bottom end contacts the base and the body surrounds the pipe ends, forming a barrier between an area surrounding the pipe ends and the base external to the body on which the concrete will be poured such that after the concrete slab is formed, a portion of the body extends above the concrete and the open top provides access to the pine ends within the recess. ### Claim 12 (depends on 11) The pipe protector of claim 11 wherein the plate is secured to the body. ### Claim 13 (depends on 11) The pipe protector of claim 11 wherein the plate is secured to the body above the bottom end. ### Claim 14 (depends on 11) The pipe protector of claim 11 further comprising a supporting structure for supporting the plate in the recess. ### Claim 15 (depends on 14) The pipe protector of claim 14 wherein the supporting structure is a lip directed toward the recess for supporting the plate in the recess. ### Claim 16 (depends on 11) The pipe protector of claim 11 wherein the securing structure comprises an elongated member for driving into the base to a depth sufficient to restrict the body from moving thereon. ### Claim 17 (depends on 11) The pipe protector of claim 11 wherein at least one opening on the plate is formed by removing at least one concentric ring from a set of concentric rings having a weakened perimeter on the plate so as to customize the diameter and spatial orientation of such at least one opening to fit a corresponding pipe end.
