Support system for use in construction

A support system for use in construction (100), comprising:

• four support members (102), each of the four support members (102) having a jack (110), a lower attachment plate (112) at a support member lower section (114), and an upper attachment plate (116) at a support member upper section (118), and a cap (120);
• the jack (110) having a foot (124) at a jack lower end (206) and a crank shaft (208) penetrating through a jack first side (210) and a crank shaft coupling attachment (407) accessible from a jack second side (312) opposite the jack first side (210);
• the cap (120) coupled to the support member (102) at a support member top (122);
• eight connectors (104);
• two connecting shafts (108), each connecting shaft (108) sized to couple to two of the crank shaft coupling attachments (407);
• wherein each support member (102) includes an extension tube (214) detachably coupleable to the jack (110);
• the extension tube (214) having an extension tube height (216);
• the upper attachment plate (116) affixed to the extension tube (214);
• and
• the lower attachment plate (112) affixed to the jack (110);
• the upper attachment plate (116) having an upper attachment plate thickness (414) and including an upper attachment plate first downward opening (250) immediately adjacent the support member (102) and an upper attachment plate second downward opening (252) immediately adjacent the support member (102), the upper attachment plate first downward opening (250) and the upper attachment plate second downward opening (252) identically sized;
• and
• the each of the connectors (104) has a first downward capture member (402) at a connector first end (406) and a second downward capture member (404) at a connector second end (408), the first downward capture member (402) having a first downward capture member outer surface (410) descending downwardly perpendicular to connector main section (412) between the connector first end (406) and the connector second end (408) at a length at least four times greater than the upper attachment plate thickness (414), the first downward capture member outer surface (410) adapted for contacting one of the upper attachment plate (116) and the lower attachment plate (112), and
• the second downward capture member (404) having a second downward capture member outer surface (416) descending downwardly perpendicular the connector main section (412) at a length at least four times greater than the upper attachment plate thickness (414), the second downward capture member outer surface (416) adapted for contacting the other of the upper attachment plate (116) and the lower attachment plate (112);
• the lower attachment plate (112) having a lower attachment plate thickness (418) and including a lower attachment plate first downward opening (254) immediately adjacent the support member (102) and a lower attachment plate second downward opening (256) immediately adjacent the support member (102), the lower attachment plate first downward opening (254) and the lower attachment plate second downward opening (256) identically sized;
• the lower attachment plate first downward opening (254) sized to the upper attachment plate first downward opening (250);
• and
• the lower attachment plate second downward opening (256) sized to the upper attachment plate second downward opening (252);
• the lower attachment plate first downward opening (254) coaxial with to the upper attachment plate first downward opening (250);
• and
• the lower attachment plate second downward opening (256) coaxial with to the upper attachment plate second downward opening (252);
• and
• wherein each support member (102) has a jack coupler (212) sized to couple to the jack (110) without interference to the crank shaft (208) and the crank shaft coupling attachment (407) and the jack coupler (212) sized to couple to the extension tube (214);
• the jack coupler (212) having a jack coupler first passage (218) laterally therethrough;
• the jack coupler (212) having a jack coupler second passage (220) laterally therethrough perpendicular to the jack coupler first passage (218);
• the extension tube (214) having an extension tube first passage (226) laterally therethrough and positioned for alignment with the jack coupler first passage (218);
• the extension tube (214) having an extension tube second passage (220) laterally therethrough perpendicular to the extension tube first passage (226) and positioned for alignment with the jack coupler second passage (220);
• a jack coupler first toggle pin (222) sized to the jack coupler first passage (218) and the extension tube first passage (226);
• and
• a jack coupler second toggle pin (224) sized to the jack coupler second passage (220) and the extension tube second passage (220).
