## Abstract

A forming system includes a frame and two forming walls. The two forming walls are positioned at a distance from each other to define a first vertical wall course. One forming wall is supported by the frame such that the one forming wall can be translated toward or away from the respective other forming wall. The frame can be raised to raise the two forming walls to be positioned to pour a second vertical course on top of the first vertical course. The translation of the one forming wall allows for the pouring of the first vertical course with horizontally extending rebar that extends through the one forming wall outside of the first vertical wall course, to tie in to a subsequently poured floor slab. The translation permits the vertical raising of the one forming wall, without striking the extending rebar, to pour the second vertical course on the first vertical course. A worker's platform is provided that is supported by the frame and vertically movable by raising the frame. The worker's platform is located below the one forming wall on a side of the one forming wall opposite the respective other forming wall and is retractable to also clear the extending rebar during raising of the frame.

## Claims

### Claim 1

A forming system, comprising:
a frame;
two forming walls that are positioned at a distance from each other to define a thickness of a vertical void to be filled with concrete to form a first vertical wall course, one forming wall of the two forming walls is supported by the frame such that the wall can be translated toward or away from the respective other forming wall of the two forming walls, the frame can be raised to raise the two forming walls to be positioned to pour a second vertical course on top of the first vertical wall course,
wherein the translation of the one forming wall allows for the pouring of the first vertical wall course having horizontally extending rebar that extends outside of the first vertical wall course to tie in a floor slab to the first vertical wall course, and for the vertical raising of the two forming walls to pour the second vertical wall course on the first vertical wall course without interference of the vertical movement of the one forming wall with the extending rebar, wherein the one forming wall is movable horizontally away from the respective other forming wall by a distance sufficient to clear the extending rebar.

### Claim 2 (depends on 1)

The forming system according to claim 1, further comprising a worker's platform supported by the frame and vertically movable by raising the frame, the worker's platform located below the one forming wall on a side of the one forming wall opposite the respective other forming wall, wherein the worker's platform is retractable to also clear the extending rebar.

### Claim 3 (depends on 2)

The forming system according to claim 2, wherein the worker's platform is hung pivotally from the frame and is pivoted away from the one forming wall to clear the extending rebar.

### Claim 4 (depends on 2)

The forming system according to claim 2, wherein the worker's platform is hung from the frame and is folded back to clear the extending rebar.

### Claim 5 (depends on 1)

The forming system according to claim 1, wherein a forming strip is positioned onto the one forming wall to form around the extending rebar and forms part of the forming surface of the one forming wall.

### Claim 6 (depends on 5)

The forming system according to claim 5, wherein when the one forming wall is moved away from the respective other forming wall after the poured concrete between the two forming walls has sufficiently set or cured, the forming strip detaches from the one forming wall and is thereafter stripped off of the first vertical wall course and from around the extending rebar.

### Claim 7 (depends on 1)

The forming system according to claim 1, wherein the two forming walls are hung from the frame and the one forming wall is hung with a rolling connection to be translated toward or away from the respective other forming wall.

### Claim 8 (depends on 1)

The forming system according to claim 1, wherein the worker's platform is hung pivotally from the frame and is pivoted away from the one forming wall to clear the extending rebar; and
a forming strip is positioned onto the one forming wall to form around the extending rebar and forms part of the forming surface of the one forming wall.

### Claim 9 (depends on 8)

The forming system according to claim 8, wherein when the one forming wall is moved away from the respective other forming wall after the poured concrete between the two forming walls has sufficiently set or cured, the forming strip detaches from the one forming wall and is thereafter stripped off of the first vertical wall course and from around the extending rebar.

### Claim 10 (depends on 9)

The forming system according to claim 9, wherein the two forming walls are hung from the frame and the one forming wall is hung with a rolling connection to be translated toward or away from the respective other forming wall.

### Claim 11 (depends on 1)

The forming system according to claim 1, wherein the worker's platform is hung from the frame and is folded back to clear the extending rebar;
and wherein a forming strip is positioned onto the one forming wall to form around the extending rebar and forms part of the forming surface of the one forming wall.

### Claim 12 (depends on 11)

The forming system according to claim 11, wherein when the one forming wall is moved away from the respective other forming wall after the poured concrete between the two forming walls has sufficiently set or cured, the forming strip detaches from the one forming wall and is thereafter stripped off of the first vertical wall course and from around the extending rebar.

### Claim 13 (depends on 12)

The forming system according to claim 12, wherein the two forming walls are hung from the frame and the one forming wall is hung with a rolling connection to be translated toward or away from the respective other forming wall.
