Method for constructing parking structures
The method is for constructing parking structures, each parking structure having a site and being of the type including a plurality of parking decks, each deck being defined by a plurality of steel beams supporting a plurality of cementitious panels. The method is of the type wherein each panel is manufactured by pouring concrete into a form remote from the site. The improvement comprises: transporting a plurality of forms to premises proximal to the site; and constructing the panels.
1 . An improved method for constructing parking structures,
each parking structure having a site and being of the type including a plurality of parking decks, each deck being defined by a plurality of steel beams supporting a plurality of cementitious panels,
the method being of the type wherein each panel is manufactured by pouring concrete into a form at a premises proximal to the site, the improvement comprising:
transporting a plurality of the forms to the premises;
receiving, at the premises, concrete that has been mixed remote from the premises; and
constructing the panels, wherein constructing the panels comprises, for each panel:
pouring the concrete into a respective one of the forms at the premises, the concrete hardening in the respective form to provide a green panel;
removing the green panel from the respective form, comprising tilting the respective form and the green panel by a tilt table to a vertical position; and
placing the green panel, removed from the respective form, in a vertical position in a comb that supports multiple green panels and curing the green panel in the comb at the premises to provide a cured panel.
2 . The method according to claim 1 , wherein the concrete is:
shipped to the premises in a ready-mix truck; or
shipped to the premises in a mixer truck.
3 . The method according to claim 1 , wherein the concrete is delivered to a crane-supported bucket at the premises and delivered thereby to the respective form.
4 . The method of claim 1 , wherein removing the green panel from the respective form involves tilting the respective form and the green panel 90′ to the vertical position by the tilt table.
5 . The method according to claim 1 , wherein the green panel, once tilted by the tilt table, is moved by a crane to the comb.
6 . The method according to claim 5 , wherein the comb has been transported to the premises.
7 . The method of claim 5 , wherein the tilt table has been transported to the premises.
8 . The method of claim 7 , wherein the parking garages are completed in seriatim and, once the panels of a garage in the series have been completed, the forms and tilt table are transported to a further premises proximate a site of the next garage in the series to be completed.
9 . The method of claim 1 , wherein a granular material used for the concrete is stored in a silo, the silo being enrobed in an electrical blanket, to provide for flowability of the granular material in cold conditions.
10 . The method of claim 1 , wherein the water used for the concrete is heated in cold conditions.
