A support structure formed in one or more sections, the support structure having vertical legs which are extensible at upper and lower ends thereof and being able to support concrete building forms at two different levels utilizing horizontal saddle beams near the top thereof to support a building form at one level with the extensible upper legs supporting a second building form at a second level. The saddle beams each include a pair of vertically spaced support surfaces preferably in the form of a pair of outwardly extending flanges proximate the top and bottom of a central web extending outwardly from the beam to form opposed surfaces, flanges or ledges and a connector at either end of the saddle beams, for securing the saddle beams to the legs, each connector preferably connected to the saddle beam by a bracket supported by the spaced support surfaces and secured to the web of the saddle beam to abut the opposed flanges. The vertical legs are extensible by extension tubes, the extension tubes and portion of the legs from which the extension tubes extend having equally spaced aligned holes therethrough including diametrically opposed semi-circular apertures in the extension tubes at the ends of the extension tubes extending from the legs. A U-shaped connector pin connects the extension tubes and legs together.
A support structure formed in one or more sections, the support structure having vertical legs which are extensible at upper and lower ends thereof and being able to support concrete building forms at two different levels utilizing horizontal saddle beams near the top thereof to support a building form at one level with the upper legs when extended supporting a second building form at a second level, the horizontal saddle beams each comprising a pair of vertically spaced support surfaces and a connector at either end of the beam, for securing the saddle beams to the legs, each connector being connected to the saddle beam by a member supported to abut the spaced support surfaces, wherein each saddle beam comprises a central web and the pair of spaced support surfaces comprises a pair of flanges extending outwardly from the central web proximate the top and bottom of the central web to form opposed ledges against which the top and bottom of the member abut.
A support structure formed in more than one section, the vertically surmounting sections comprising at least one lower section and at least one upper section, each of the sections of the support structure having vertically extending legs, the legs on the upper section fixedly secured to the legs of the lower section and having equally spaced aligned holes through the legs when the sections are assembled, the legs of the upper section being secured to the legs of the lower section by coupling pins having corresponding aligned apertures therethrough and by U-shaped security pins having arms for removably fitting into the aligned holes of the legs and coupling pin, wherein the upper ends of the legs of the uppermost section are extendible by extension tubes telescopically extending from the upper ends of the legs, the extension tubes and the upper ends of the legs having equally spaced aligned holes therethrough with the lower end of each extension tube comprising diametrically opposed semi-circular apertures in the tube opening through the lower end, wherein the extension tubes and upper ends of the legs are secured together by the U-shaped security pins.
A support structure for supporting concrete building forms, the support structure formed in one or more sections and having vertically extending legs which are extensible at at least one end thereof by extension tubes extending vertically from the legs, the extension tubes and portion of the legs from which the extension tubes extend having equally spaced aligned holes therethrough with the end of each extension tube proximate the leg portion having the apertures therethrough, having diametrically opposed semi-circular apertures in the extension tubes opening through the end of the extension tube and wherein the extension tubes and legs are secured together by U-shaped security pins comprising two arms for removably securing the extension tubes to the legs.
