摘要： A lifting mechanism for a concrete structure is provided through means of a void former and anchor assembly which it cast in place to provide an accurate recess in the structure having two or more spaced divergent anchors therein. The anchors define annularly aligned apertures within the recess. A lifting shackle of an arcuate configuration complimental with that of the recess is received within the recess and carries an arcuate locking bolt extendable through the aligned apertures.

摘要： First and second cast-in-place concrete slabs are maintained in alignment by cutting a semi-circular groove in an edge surface of the first formed slab, positioning a flat rectangular dowel within the groove so that the dowel extends outwardly from the edge surface, and then casting the second slab against the edge surface to embed the dowel within the second slab. A gasket is engaged with the dowel to seal the groove against the intrusion of fluid concrete as the second cast-in-place. The gasket also serves to space the dowel from the groove to accommodate limited lateral movement of the dowel and groove relative to one another.

摘要： A polymeric chair having a rebar cradle and legs of a T-shaped cross-section diverging downwardly from the cradle. The outer surface portions of the legs are arcuate and define segments of a cone. Inwardly extending web portions reinforce the legs and provide feet at the distal ends of the legs disposed to the inside of the outer surface portions. A flat sand plate for the chair has radially extending slots formed therethrough which are proportioned for snug engagement with side surfaces of the feet. The slots are elongate to accommodate different sized chairs having feet spaced at varying radial dimensions. The web portions taper to optimize their reinforcing function and conserve material. In one embodiment, a ring is formed integrally with the legs intermediate the table and the distal ends of the legs. The chair is of a unitary construction and may have an integrally formed strap for extension over the cradle to secure a rebar in place.

摘要： A radially expansible sleeve to provide part of a drop-in anchor for receipt in a bore formed in a concrete structure. The sleeve has arcuate protrusions with knife-like distal edges extending therearound. Upon radial expansion of the sleeve, the knife-like edges cut into the interior surface of the bore to anchor the sleeve in place.

摘要： An assembly for use in the formation of adjacent concrete slabs to provide a flat rectangular dowel engaged between the slabs. The assembly comprises a pocket which is cast in place in the edge portion of the first slab to be formed, with the dowel fully confined within the pocket. After the formation of the first slab, the dowel is partially withdraw from the pocket and the second slab is formed in place against the first slab, with the dowel in spanning relationship to the respective slabs. In the preferred embodiments, the pocket comprises a monolithic plastic box having complimental generally rigid upper and lower sections movable between a closed condition defining the pocket therebetween and an open condition exposing the pocket interiorly. One edge of the pocket is formed with an opening through which the dowel passes as it moves between the fully confined and the partially withdrawn positions. In certain embodiments, a sealing element or door is provided to close the opening during the formation of the first slab. Seal elements are also provided to seal the pocket against the intrusion of concrete during the formation-of the second slab.
