Post-tension intersection chair
View Patent ↗A chair for supporting and spacing post-tension cables having a generally tapered body with an upper receiving area for securing the cables and a planar base adapted to rest on a flat support surface. The body has inner and outer surfaces that are substantially complementary to one another to allow a plurality of chairs to be stacked together. The receiving area includes posts extending upwardly between notches. The posts define passageways for guiding the cables into the notches. Detents project inwardly from the tops of the posts and fixedly retain the bars within the passageways. The chair may be formed from a resilient polymeric material.
1. A post-tension cable chair, comprising:
a generally tapered body including a plurality of spaced legs having apertures therebetween sized to freely admit the flow of poured concrete therethrough;
said body having an inner surface and an outer surface, said inner and outer surfaces being substantially complementary to each other to allow a plurality of chairs to be stacked within one another for storage and shipment;
a plurality of resilient posts projecting upwardly from an upper receiving area and adapted to secure post-tension cables engaged thereby in intersecting relationships to each other;
at least one notch formed between adjacent pairs of posts to receive and support a cable, said posts defining a passageway above said notch; and
a pair of detents projecting laterally outwardly from each post and angled inwardly toward a center of the chair such that opposing detents on adjacent posts define outwardly sloped surfaces for guiding a cable into said passageway.
2. The post-tension cable chair of claim 1 , wherein for each post, said pair of detents project laterally outwardly from opposite edges of said post, one detent extending laterally outwardly from each opposite edge thereof.
3. A post-tension cable chair, comprising:
a generally tapered body including a plurality of spaced legs having apertures therebetween sized to freely admit the flow of poured concrete therethrough;
said body having an inner surface and an outer surface, said inner and outer surfaces being substantially complementary to each other to allow a plurality of chairs to be stacked within one another for storage and shipment;
a plurality of resilient posts projecting upwardly from an upper receiving area and adapted to secure post-tension cables engaged thereby in intersecting relationships to each other;
at least one notch formed between adjacent pairs of posts to receive and support a cable, said posts defining a passageway above said notch; and
an inwardly extending flanged rim proximate a lower extent of each said notch, said flanged rim defining a saddle for supporting a cable inserted within said passageway.
4. The post-tension cable chair of claim 3 , further comprising an outwardly extending flanged rim formed along adjacent spaced apart legs and around each said aperture therebetween.
5. The post-tension cable chair of claim 3 , wherein said inwardly extending flanged rim is inwardly cantilevered from said receiving area.
