Abstract: A sleeve device for increasing shear capacity of a reinforced concrete slab includes a hollow member, stud members, and head members. The hollow member is positioned on and fastened to a bottom formwork defining the reinforced concrete slab. The hollow member creates a void in the reinforced concrete slab. The stud members are connected to opposing sides of the hollow member directly or using connectors. A first stud member is connected to an upper portion of the hollow member and oriented in a downward direction. A second stud member is connected to a lower portion of the hollow member and oriented in an upward direction. The head members are operably coupled to distal ends of the stud members and embedded in the reinforced concrete slab. The head members transfer shear forces across the sleeve device through an interaction between the head members and the concrete surrounding the stud members.

Abstract: A post-installed sleeve device is provided for compensating loss of shear capacity of a concrete slab due to a hole drilled in the concrete slab. The sleeve device includes a hollow member of, for example, a cylindrical shape, and a lower sandwich member and an upper sandwich member shaped, for example, as ring members. The hollow member is inserted into the drilled hole such that an upper section of the hollow member extends above a top surface of the concrete slab. The lower sandwich member includes an inner edge rigidly attached to a bottom edge of the hollow member. The upper sandwich member includes an inner edge engageably connected to the upper section of the hollow member. The upper sandwich member and the lower sandwich member sandwich the concrete slab surrounding the drilled hole therebetween for compensating the lost shear capacity of the concrete slab due to the drilled hole.

Abstract: A sleeve device for transferring bending moments induced in a reinforced concrete slab includes a generally hollow member and tension rebars. The hollow member is positioned and fastened on a bottom formwork defining the reinforced concrete slab. The tension rebars are connected to opposing sides of an upper portion of the hollow member either directly or using rebar connectors. The hollow member creates a void in the reinforced concrete slab by pouring of concrete around an outer wall of the hollow member. The hollow member transfers compressive stresses across a bottom of the hollow member and tensile stresses through the tension rebars and the upper portion of the hollow member. The affixed tension rebars are spliced with regular reinforced concrete slab rebars to develop tensile stresses that are transferred through the relatively stiffer hollow member to retain a slab moment capacity.

Abstract: A tubular housing having a reciprocating rod directed therethrough, with the reciprocating rod having a handle at an uppermost end of the reciprocating rod, with a generally U-shaped frame mounted to the tubular housing, with the reciprocating rod extending within the U-shaped frame securing a head member within the U-shaped frame secured to the rod, with the U-shaped frame having a plate facing the head member, with the plate including a V-shaped slot and the head member having a cavity facing the slot to capture a golf ball between the head member and the slot. A mounting bracket is fixedly secured to the housing, having a spring plate at a first end of the mounting bracket to engage a golf ball bag, with a positioning spike secured to the mounting bracket, such that the positioning spike extends beyond the tubular housing, such that inverting the tubular housing permits projecting the spike member into a golf green turf to position the tubular housing during periods of non-use.

Abstract: A collapsible, palletized bin container is provided which has separate compartments therewithin. Each compartment is designed to house a separate fluid-filled bag. Dividers are located within the container which form the discrete compartments. Each divider has tabs which are received within notches in sidewalls of the container. The notches allow the sidewalls to bow slightly outward while still maintaining a tight seal with the tabs. The container is collapsible to a substantially smaller volume for transport when empty and a bar, chain and hook assembly is provided for easy removal of the fluid-filled bags when sliding the bags out of the compartments of the container.
