A system of interconnecting structural components for supporting and forming suspended concrete slabs that allow removal of form panels without disturbing the slab support posts (shores). Additional features of the system accommodate changes in suspended slab thickness, horizontal slab dimensions that are not multiples of the basic component dimensions, slab edge cantilevered form panels, attachment to walls and remote manipulation of form panels from the floor below using an erection staff. The primary system components are panels, support posts, telescopic beams, adjustable hanger connections, wall hangers, wall beams, raking shore assemblies and erection/stripping staffs. Form panels are directly supported by the shores without the use of an intermediate member (usually a beam) that is common practice in the concrete forming industry. The system reduces the number of required components that in turn reduces the capital cost to the user and improves his labor efficiency and quality of the concrete surface.

The form system of claim 10, wherein a lower surface of said translating member and said upper surface of said seat are angled to horizontal. 15. The form system of claim 14, wherein said angle creates a lateral force on said translating member when a downward force is applied to said translating member, thereby allowing said translating member to slide from an engaged position to a disengaged position when said latch is moved to an upper released position. 16. The form system of claim 14 wherein said angle is twenty-four degrees to the horizontal. 17. The form system of claim 10 wherein said translating member includes two legs with a gap between said two legs. 18. The form system of claim 17 wherein said locking mechanism includes two seats. 19. The form system of claim 18 wherein any one of said seats fits into said gap between said two legs when said translating member is moved to said disengaged position. 20. The form system of claim 12 further comprising an extraction staff, said staff having: a shaft; a manipulating head affixed at one end of said shaft, said manipulating head adapted to move said latch to said released position. 21. The form system of claim 20 wherein said translating member further includes a downward projection at an outer edge of said translating member, thereby creating a gap between one of said two legs and said downward projection. 22. The form system of claim 21 wherein said manipulating head of said extraction staff further includes a head projection projecting upwardly, said head projection fitting into the gap between said downward projection of said translating member and one of said two legs. 23. The form system of claim 22, wherein said extraction staff further comprises a fulcrum, whereby pivoting said extraction staff about said fulcrum when said head projection is inserted into said gap of said translating member causes said translating member to move to said disengaged position. 24.
