Abstract
A support work prop is described which has a main body section formed from interconnected aligned soldiers. Head and base sections are provided for interconnecting the upper and lower ends of the soldiers which may themselves be connected to either screws or jacking members, header beams or bearing plates. The prop can be readily disassembled to allow the soldiers to be employed separately so that the arrangement allows them to have a dual purpose.
Claims15
A support work propr comprising:
- a plurality of soldier members, each said soldier member comprising first and second beams and tie plates, each of said beams having a top and a bottom end, a top one of said tie plates being connected to the top ends of the first and second beams and a bottom one of said tie plates being connected to the bottom ends of the first and second beams to hold the beam parallel one to the other and spaced one from the other, the first and second beams defining at least two apertures therein, the apertures of the first beam being aligned with those of the second beam;
- connecting means that releasably secure said soldier members together intermediate their top and bottom ends to form a main body section in which said soldier members are oriented parallel one to the other
- said connecting means being attached to each of said soldier members by way of the at least one pair of aligned apertures therein;
- a head section comprising a head plate that releasably secures the top ends of said soldier members together;
- and
- a base section comprising a base plate that releasably secures the bottom ends of said soldier members together, whereby said support work prop is dismountable into its component parts.

A support work prop comprising:
- a plurality of solider members, each said solider member comprising first and second beams and tie plates, each of said beams having a top and bottom end, a top one of said tie plates being connected to the top ends of the first and second beams and a bottom one of said tie plates being connected to the bottom ends of the first and second beams to hold the beams parallel one to the other spaced one from the other, the first and second beams defining at least two apertures therein, the apertures of the first beam being aligned with those of the second beam;
- connecting means that releasably secure said soldier members together intermediate their top and bottom ends to form a main body section, said main body section comprising at least a first subsection and a second subsection, each subsection including a plurality of soldier members releasably secured intermediate their top and bottom ends by said connecting means such that the soldier members are radially spaced around a center axis, the soldier members being parallel one to the other and to the center axis;
- said connecting means being attached to each of said soldier members by way of the at least one pair of aligned apertures therein;
- a head section comprising a head plate that releasably secures the top ends of said soldier members of said first subsection together;
- and
- a base section comprising a base plate that releasably secures the bottom ends of said soldier members of said second subsection together, said bottom ends of said soldier members of said first subsection being releasably secured to the top ends of said soldier members of said second subsection with the center axes of the sections aligned, whereby said support work prop is dismantable into its component parts.
