Abstract
A temporary load support system including a permanent portion comprising a stud having a stem and crosspiece, and a removable load support member comprising a cavity, configured to receive the stud and engage the crosspiece upon relative rotation of the support member relative to the stud while the stud is received in the cavity, whereby the support member is removably attached to the stud so as to enable load transfer from the support member to the stud.
Claims57
A removable load support system configured to support a load at a point adjacent a side surface of a pole, comprising:
- a t-shaped stud affixed to the pole and extending out from the surface in a direction substantially normal to the surface, the t-shaped stud including:
- a stem portion extending in a direction substantially normal to the surface,
- the stem having a base portion comprising a portion of the t-shaped stud proximal to the surface and attached to the surface so as to transfer a load force to the pole, and
- a crosspiece carried by the stem portion so as to enable load forces to be transferred from the crosspiece to the stem portion, the crosspiece extending laterally from the stem portion to form a t-shaped stud;
- and
- a removable support member having proximal and distal ends, the removable support member being configured at the proximal end to releasably attach to the t-shaped stud so as to transfer a load force from the support member to the t-shaped stud, the support member defining a cavity adjacent its proximal end configured to receive the t-shaped stud when the support member is slipped over the t-shaped stud and the proximal end of the support member is brought adjacent the surface, the support member further defining a first slot and a second slot configured to align with and receive the crosspiece as the support member is tamed on the t-shaped stud, the removable support being attachable to the t-shaped stud by sliding over the t-shaped stud and rotating the removable support so that the crosspiece of the t-shaped stud is received in the slots.

A removable load support system configured to support a load adjacent a surface extending vertically, comprising:
- a t-shaped stud affixed to the surface, the t-shaped stud further comprising a stem having a base at a proximal end attached to the surface and a distal end, and a crosspiece attached to the stem at the distal end, the cross piece having a length dimension greater than the width of the stem and extending substantially horizontally from the stem on both sides,
- a removable support member having proximal and distal ends and engageable with the t-shaped stud, the removable support member defining a cavity at the proximal end configured to receive the t-shaped stud, and further comprising first and second slots opening on the cavity which are engageable with the t-shaped stud by placing the removable support over the t-shaped stud and rotating the removable support so that the cross piece of the t-shaped stud extends into the slots and thereby mechanically engages the removable support, whereby a load force can be transferred from the support member to the t-shaped stud attached to the surface.
A removable load support system configured for supporting a load from an object comprising:
- a stud incorporating a stem having proximal and distal ends, carried by the object, the proximal end adjacent the object, the stud being configured to transfer a load force to the object through the proximal end;
- a crosspiece incorporated in the stud so as to transfer a load force to the stud, the crosspiece extending laterally from the stud;
- a support member having a proximal end and a distal end and defining a slot, the support member being configured for temporary attachment to the stud at the proximal end of the support member by slipping the support member over the stud and subsequently rotating the support member to provide a mechanical interlock between the support member and the stud and crosspiece, the slot being configured to receive the crosspiece upon rotation of the support member, such that a load force can be transferred from the support member to the stud, and thereby to the object.
