Abstract

A prefabricated wall section apparatus includes a pair of pressure treated plywood panels having a plurality of furring strips attached to one side of each panel. A plurality of spacing tie members space the pair panels a predetermined distance apart. The panels are held together by a plurality of fastener members for attaching the panels together, spaced by the spacing tie members with the fastener members attached through the furring strips and panels, so that the furring strips act as reinforcing strips as well as furring strips for the prefabricated wall. Column and beam forming internal walls are located between the pair of connected panels to make three sides of one or two columns and one beam form between the pair of panels so that the prefabricated wall section can be set up and concrete poured therein. The prefabricated wall sections are attached to a foundation adjacent each other so that two adjacent prefabricated wall sections can form one column form. A plurality of Waler Brackets are attached to one side of each panel. The brackets may be attached flat with one end under a furring strip and bent perpendicular to the panel for placing walers therein for additional support during the pouring of the columns and beam. The column and beam form walls also isolate interior space for wall insulation.

Claims

1. A prefabricated wall section comprising:

a pair of panels;

a plurality of pressure treated wood furring strips attached to one side of each panel and having predrilled holes through said furring strips and panels;

a plurality of spacing tie members for spacing said pair of panels at predetermined distance;

a plurality of fastener members for attaching said panels together, spaced by said spacing tie members, said fastener tie members being attached through the predrilled holes in said furring strips and panels;

column forming walls located between said pair of connected panels to make at least three sides of one column form between said pair of panels, whereby said prefabricated wall section can be set up and a column poured therein; and

a plurality of waler brackets attached to each prefabricated wall section panel for attaching walers thereto each waler bracket being flat along the prefabricated wall section with one end extending under one of said pluralities of furring strips, whereby each waler strip may be bent for attaching walers.

2. Prefabricated wall section in accordance with claim 1 in which said plurality of fastener members are threaded fasteners.

3. Prefabricated wall section in accordance with claim 2 in which said furring strips are stapled to each said panel.

4. A prefabricated wall section in accordance with claim 3 in which said predrilled holes are countersunk for receiving countersinking threaded fasteners.

5. A prefabricated wall section in accordance with claim 4 in which said pair of panel are pressure treated plywood panels.

6. A prefabricated wall section in accordance with claim 1 in which each waler bracket has a weakened portion adjacent the attached furring strip whereby each waler bracket can be bent to an approximately perpendicular position to the pair of panels, and each waler bracket has a generally vertically extending portion on the end thereof, whereby walers can be placed therein once the waler brackets are bent into their perpendicular position;

7. A prefabricated wall section in accordance with claim 6 in which each waler bracket has a weakened portion having a removed portion adjacent to each furring strip and may be broken off at the weakened portion.

8. A prefabricated wall section in accordance with claim 1 in which a plurality of reinforcing members are placed within each column form portion.

9. A prefabricated wall section in accordance with claim 8 in which each prefabricated wall section forms at least three sides of two column forms so that when attached to adjacent prefabricated wall sections, two columns are formed therein.

10. A prefabricated wall section in accordance with claim 7 in which a beam forming wall is located between said pair of connected panels to make a beam form interconnected with said column forms for pouring said beams and columns at the same time.

11. A prefabricated wall section in accordance with claim 1 in which insulation is attached between said prefabricated wall section in between said column forming walls located therebetween.
