Tilt-up concrete form brace
View Patent ↗A brace for use in tilt-up construction is disclosed. The brace includes a bottom surface and a vertical side surface. The bottom surface of the brace is affixed to a permanent horizontal surface (e.g., a slab) in a manner that allows the brace to be removed without damaging the permanent horizontal surface. The vertical side surface of the brace is attached to a concrete pour form. The bottom surface of the brace is affixed to the permanent horizontal surface using an adhesive. Alternatively, a shoe is attached to the permanent horizontal surface and the brace sits in the shoe. A flange is releasably securable with the brace to batter the form when the flange is place in contact therewith. Alternatively, the shoe has an upwardly extending inclined ramp that is operable to orient the brace so that the vertical side surface of the brace is disposed at a battering angle to batter the form.
1. A brace kit having component parts capable of being assembled in the field for reinforcing a form member used in the construction of a form atop a support surface, comprising:
a brace shoe having a lower surface adapted to be secured to the support surface and a first locking structure;
a brace member having a second locking structure and configured to directly interlock with said first locking structure of said brace shoe so that said brace member is releasably interlocking with said brace shoe, said brace member having an upwardly extending form facing surface extending generally perpendicular to said lower surface of said brace shoe; and
a flange member releasably securable with said brace member and having a form engaging surface disposed at an oblique angle substantially along its entire length relative to the form facing surface of said brace member, wherein an assembled brace acts to angle the form member with respect to the support surface when the form engaging surface of said flange member is placed in contact therewith.
2. The brace of claim 1 further comprising an adhesive material affixed to the lower surface of said brace shoe and adapted to temporarily secure said brace shoe to the support surface.
3. The brace of claim 2 wherein said adhesive material is double-sided adhesive tape.
4. The brace of claim 1 wherein said brace member is manufactured of plastic material.
5. The brace of claim 1 wherein said flange member is manufactured of plastic material.
6. The brace of claim 1 wherein said brace shoe is manufactured of plastic material.
7. The brace of claim 1 further comprising a pair of aligned apertures extending respectively through said brace member and said flange member and adapted to receive a fastener for securing the brace to the form member.
8. A brace kit having component parts capable of being assembled in the field for reinforcing a form member used in the construction of a form atop a support surface, comprising: a brace shoe having an upper surface defining a first locking structure and a lower surface adapted to be secured to the support surface; and a brace member having a base surface defining a second locking structure configured to positively interlock with said first locking structure of said brace shoe in a two-piece lock so that said brace member releasably locks into place in said brace shoe to prevent all substantial relative motion therebetween, said brace member having an upwardly extending form facing surface extending generally perpendicular to said base surface, wherein an assembled brace defines a generally vertically-oriented form facing terminal plane adapted to contact and position the form member with respect to the support surface, wherein said second locking structure comprises a pair of tabs disposed adjacent to said upwardly extending form facing surface and a tongue disposed at a remote end of said brace member.
9. The brace of claim 8 , wherein said brace member includes a pair of nail flanges disposed both adjacent to said upwardly extending form facing surface and on opposing sides of said brace member, and for each pair of tabs and nail flanges, one such tab projects from one such nail flange opposite said upwardly extending form facing surface.
10. A brace kit having component parts capable of being assembled in the field for reinforcing a form member used in the construction of a form atop a support surface, comprising: a brace shoe having an upper surface defining a first locking structure and a lower surface adapted to be secured to the support surface; and a brace member having a base surface defining a second locking structure configured to positively interlock with said first locking structure of said brace shoe in a two-piece lock so that said brace member releasably locks into place in said brace shoe to prevent all substantial relative motion therebetween, said brace member having an upwardly extending form facing surface extending generally perpendicular to said base surface, wherein an assembled brace defines a generally vertically-oriented form facing terminal plane adapted to contact and position the form member with respect to the support surface, wherein said two-piece lock is a snap-fit lock.
11. The brace of claim 10 , wherein said snap-fit lock includes a resilient latch which positively engages a complementary tab such that said resilient latch must be individually disengaged from said tab in order to releasably separate said brace member from said brace shoe.
12. The brace of claim 11 , wherein said snap-fit lock includes a tongue which positively engages a complementary pocket, said tongue being fixed within said pocket by engagment of said resilient latch with said tab.
