US 5,050,364 A · Two-part anchor bolt holder

Abstract

The invention disclosed here is an anchor bolt holder that is designed to be used in setting an anchor belt in a concrete slab. The holder is a two-part system having a base, and a sleeve connectable to a socket in the base. The sleeve is adapted to receive and hold an anchor bolt's shank. Prior to pouring the slab, the base is first mounted to the decking or forming surface that underlies the slab. After certain other pre-pour items have been installed over the decking, the sleeve is then plugged into the base's socket and supports the anchor bolt vertically. The combined function of the sleeve and base is to fix the bolt in position during both the pour and cure phases of the slab, so that the bolt is held vertically with its threads projecting above the slab's top surface. The sleeve has openings through its sidewall that are sufficiently large to allow wet concrete the bolt's shank within the sleeve. Also, the sleeve is adapted to provide vertical adjustability of the anchor bolt's height relative to the decking, thus providing a way to accommodate bolt height to variations in slab depth.

Dependent claims

An anchor bolt holder for use in setting an anchor bolt in a concrete slab and the like, the anchor bolt having an elongated shank with a threaded end, and an opposite end extending laterally relative to said shank, said anchor bolt holder comprising:

a base member, mountable to a forming surface that underlies said concrete slab during pouring of the same;
and
a hollow, cylindrically-shaped sleeve member, said sleeve member being connectable to said base member in a manner so that said sleeve member is in a generally vertically upstanding position relative to said base member, and further, said sleeve member receiving at least a portion of said anchor bolt's elongated shank, said sleeve member having an elongated vertical split extending along at least one side thereof, said split being defined by a pair of spaced-apart lateral side edges, said edges being adapted to grip therebetween said anchor bolt's laterally-extending end, for holding said bolt in a certain position above said forming surface.

A two-part anchor bolt holder for use in setting an anchor bolt in a concrete slab and the like the anchor bolt having an elongated shank with a threaded end, and an opposite end extending laterally relative to said shank, said anchor bolt holder comprising:

a base member, mountable to a forming surface that underlies said concrete slab during pouring of the same, said base member having an upwardly opening socket;
and
a hollow sleeve member having an upper end and a lower end, said sleeve member being splint apart along one side thereof from its upper end to near its lower end, and wherein at least a portion of said anchor bolt's elongated shank is received within said sleeve member and extends upwardly through said upper end of said sleeve member, and said anchor bolt's laterally-extending end projects through said split-apart side of said sleeve member, the lateral edges thereof gripping said laterally-extending end, for holding said anchor bolt in a certain position above said forming surface, and said sleeve member's lower end being shaped for male/female fitment into said upwardly opening socket of said base member in a manner so as to releasably connect said sleeve member to said base member, and to hold said anchor bolt in a generally vertical position when said sleeve member is connected to said base member, said sleeve member normally being connected to said base member after said base member has been mounted to said forming surface.

A two-part anchor bolt holding apparatus, for setting an anchor bolt having an elongated shank in a concrete slab and the like, comprising:

a base member, mountable to a forming surface that underlies said concrete slab during pouring of the same;
and
a hollow sleeve member, releasably connectable to said base member in a manner so that said sleeve member is in a generally vertically upstanding position relative to said base member, said sleeve member normally being connected to said base member after said base member has been mounted to said forming surface, and further, said sleeve member being adapted to receive therein at least a portion of said anchor bolt's elongated shank, and to support said anchor bolt in a generally vertically aligned position above said forming surface when said sleeve member is connected to said base member, in a manner so that an upper threaded end portion of said bolt projects upwardly above said concrete slab after it is poured and has set, said sleeve member having at least one opening along its sidewall, said at least one opening being sufficiently large to permit, during pouring of said concrete slab, wet concrete to contact said shank portion received in said sleeve member.
