Abstract

A building system and apparatus for forming a wall on a footing. U-shaped channels and H-shaped or T-shaped members coupled at their sides by rigid links hold foam panels in a desired spaced relationship. Vertically oriented panels aligned and connected by T-shaped members or horizontally oriented panels stacked with and connected by H-shaped members are inserted into the U-shaped channels to form a structure of the desired length. Concrete is poured between the panels and members where it hardens to form a structural wall. The planar surfaces of the U-shaped, H-shaped and T-shaped members enable the members to be extruded, thereby substantially reducing member production costs. Furthermore, widely available conventional foam panels can be used, reducing panel production costs.

Claims

1. A substantially vertically oriented apparatus for holding forms in a desired spaced relationship until hardenable liquid building material is poured and hardens between the forms, said apparatus comprising:

a plurality of elongated members each oriented with a longitudinal axis extending substantially vertically, said elongated members being T-shaped in cross section and including planar surfaces for engaging the forms;

a plurality of pairs of U-shaped elongated members, the U-shaped members of each pair extending in a substantially parallel spaced relationship, defining substantially parallel spaced channels for receiving bottom edges of the forms, said U-shaped members including planar surfaces for engaging the forms; and

a plurality of substantially rigid links connected to sides of said T-shaped elongated members, said U-shaped members and said T-shaped members retaining the forms in the desired spaced relationship, and said links leaving sufficient open space between said T-shaped members to allow the liquid building material to be poured between said T-shaped members.

2. The apparatus as defined in claim 1, wherein a length of a leg of said T-shaped elongated member is no longer than a length of a flange of said T-shaped member.

3. The apparatus as defined in claim 1, wherein said T-shaped and U-shaped elongated members comprise plastic material.

4. The apparatus as defined in claim 1, wherein said T-shaped and U-shaped elongated members comprise material which can be connected to and support substantially rigid building material.

5. The apparatus as defined in claim 4, wherein said substantially rigid building material comprises conventional drywall.

6. The apparatus as defined in claim 1, wherein said T-shaped and U-shaped elongated members comprise extruded plastic material.

7. The apparatus as defined in claim 1, wherein said T-shaped and U-shaped elongated members comprise steel.

18. The apparatus as defined in claim 1, including further rigid links connected to sides of said U-shaped elongated members to retain said U-shaped members in a desired spaced relationship.

19. The apparatus as defined in claim 1, wherein said pairs of U-shaped elongated members are coupled to a footing for maintaining said pairs of U-shaped members in said substantially parallel spaced relationship.

8. A system for forming a structure, said system comprising:

a plurality of pairs of U-shaped elongated members, said U-shaped elongated members of each pair extending in a substantially parallel spaced relationship, defining substantially parallel spaced channels;

a plurality of substantially vertically oriented elongated and planar panels laterally spaced by insertion of bottom edges of said panels into said channels defined by said U-shaped elongated members;

substantially vertically oriented T-shaped elongated members coupled together in pairs by substantially rigid links, said T-shaped elongated members coupling together adjacent ones of said panels at lateral edges of the panels; and

a top cap member defining an inverted substantially U-shaped elongated structure for receiving upper edges of said panels.

9. The system as defined in claim 8, wherein additional ones of said T-shaped elongated members and said panels are coupled to form a structure of desired length.

10. The system as defined in claim 8, wherein said T-shaped and U-shaped elongated members comprise plastic material.

11. The system as defined in claim 8, wherein concrete is poured between said panels, said T-shaped and U-shaped members, and said top cap member.

12. The system as defined in claim 8, wherein said T-shaped and U-shaped elongated members comprise extruded plastic material.

13. The system as defined in claim 8, wherein said T-shaped and U-shaped elongated members comprise steel.

14. The system as defined in claim 8, wherein said links prevent compression or expansion of the substantially parallel relationship of said panels.

15. A method of erecting a substantially vertically oriented building form system, said method comprising the steps of:

coupling a plurality of pairs of substantially parallel U-shaped elongated members to a footing with the U-shaped elongated members of each pair extending in a substantially parallel spaced relationship, defining substantially parallel spaced channels;

orienting substantially vertically a plurality of elongated, substantially T-shaped members coupled together by substantially rigid links;

inserting bottom edges of said T-shaped members into said channels of said U-shaped members;

inserting a bottom edge of substantially vertically oriented panels into said channels of said U-shaped members and coupling said panels to said T-shaped members by inserting flanges of said substantially T-shaped members into slots in lateral edges of said panels; and

creating a structure of desired length by alternately inserting said bottom edges of said panels into said channels, and inserting said flanges into said slots in said lateral edges of said panels.

16. The method as defined in claim 15, wherein a ninety degree outside corner is erected as part of said substantially vertically oriented building form system, said method comprising the further steps of:

coupling outer and inner substantially U-shaped elongated members to a footing;

inserting a bottom edge of a corner post into a channel of said outer substantially U-shaped member;

inserting a bottom of a preformed corner panel into a channel of said inner substantially U-shaped member;

inserting a bottom edge of a first further one of said substantially T-shaped members coupled by substantially rigid links into said channel of said outer substantially U-shaped member, and inserting a flange of said first further T-shaped member into a lateral edge of said corner post;

inserting a bottom of a first one of said substantially vertically oriented panels into a channel of said outer U-shaped member, and coupling said first panel to said corner post by inserting a flange of said first further T-shaped member into a slot in a lateral edge of said first panel;

inserting a bottom edge of a second further one of said T-shaped members into said channel of said inner U-shaped member, and inserting a flange of said second further T-shaped member into a lateral edge of said preformed corner panel; and

inserting a bottom of a second one of said substantially vertically oriented panels into said channel of the inner U-shaped member, and coupling said second panel to said preformed corner panel by inserting a flange of said second further T-shaped member into a slot in a lateral edge of said second panel.

17. A method of installing a component between inner and outer panel assemblies of a building form system prior to liquid building material being poured between the assemblies, said method comprising the steps of:

inserting a bottom edge of a first substantially vertically oriented, substantially T-shaped member into a channel of a U-shaped member;

inserting a bottom of a substantially vertically oriented panel into said channel, and coupling said panel to said first T-shaped member by inserting a flange of said first T-shaped member into a slot in a lateral edge of said panel;

inserting a bottom edge of a second substantially vertically oriented, substantially T-shaped member into said channel of said U-shaped member, and coupling said second substantially vertically oriented T-shaped member to said panel by inserting a flange of said second substantially T-shaped member into a slot in a lateral edge of said panel;

raising said panel vertically along tracks formed by said flanges of said first and second T-shaped members, moving the bottom of said panel out of said channel to permit installation of the component; and

lowering said panel vertically along the tracks formed by said flanges of said first and second T-shaped members until said panel is properly seated in said channel.
