(16) During wall formation, a pair of opposing wallform panels can be supported upright and tied together with a space therebetween for filling with a pourable building material, such as, for example, concrete. One or more outboard brace assemblies can be connected to one of the wallform panels to help support the panels upright. The brace assemblies can include one or more props extending between one end mounted to one of the wallform panels and an opposing end anchored to a ground surface spaced apart from the wallform panels. The props can have a length that is adjustable to facilitate positioning and alignment of the wallform panels supported by the brace assembly prior to pouring of the building material. In some examples, after the wall is formed, the brace assembly can be disconnected from the wallform panels and disassembled for temporary storage and/or transport to a different location (e.g. another level of a multi-story building) for formation of another wall portion.

(17) According to some aspects of the present disclosure, adjustable formwork systems are disclosed that can facilitate deployment, take-down, storage, and/or transport of the formwork systems without necessarily requiring disconnection of the brace assemblies from the wallform panels. In some examples, this can facilitate a more space- and time-efficient, and in some cases safer, wall formation process relative to some other processes.

(18) Referring to FIG. 1, an example formwork system 100 for forming a wall portion 102 is illustrated. In the example illustrated, the formwork system 100 comprises a pair of parallel and opposing wallform panels, including a first wallform panel 104 and a second wallform panel 106 tied to the first wallform panel 104 through a plurality of ties 108. In the example illustrated, the first and second wallform panels 104, 106 are supported upright, and are spaced horizontally apart from each other by a space 110 fillable with concrete to form the wall portion 102. Each wallform panel 104, 106 has a first side 112 facing the space 110 for forming the wall portion 102 and a second side 114 opposite the first side 112. Referring to FIG. 3, in the example illustrated, each wallform panel 104, 106 has a form lining 116 on the first side 112 for forming a wall surface of the wall portion 102, and a frame 118 comprising a plurality of interconnected frame members 118a on the second side 114 and supporting the form lining 116.

(19) Referring to FIG. 1, in the example illustrated, the formwork system 100 includes at least one brace assembly 120 on the second side 114 and mounted to the frame 118 of the wallform panel 104 for supporting the wallform panels 104, 106 upright during use. The formwork system 100 can include a plurality of brace assemblies 120 spaced horizontally apart from each other for supporting the wallform panels 104, 106.

(20) In the example illustrated, the brace assembly 120 includes a base plate 122 for anchoring to a ground surface 124 spaced horizontally apart from the wallform panel 104, a pair of vertically spaced apart swivel connectors 128 pivotably mounted to the wallform panel 104, and a pair of vertically spaced apart props 130 for supporting and aligning the wallform panel 104. Each prop 130 extends along a prop axis 132 between a first end 134 connected to the base plate 122 and a second end 136 connected to a corresponding swivel connector 128.

(21) In the example illustrated, the pair of swivel connectors 128 includes an upper swivel connector 128a and a lower swivel connector 128b below and in horizontal alignment with the upper swivel connector 128b. In the example illustrated, the pair of props 130 include an upper prop 130a and a lower prop 130b below and in horizontal alignment with the upper prop 130a. The upper prop 130a has its second end 136 connected to the wallform panel 104 through the upper swivel connector 128a and its first end 134 connected to the base plate 122, and the lower prop 130b has its second end 136 connected to the wallform panel through the lower swivel connector 128b and its first end 134 connected to the same base plate 122. Providing upper and lower props 130a, 130b connected to a common base plate 122 can help with stability of the wallform panel during deployment and use, and in some cases, can help provide for a more efficient and/or safer wall formation process, relative to providing, for example, a single prop or a pair of props anchored through separate base plates. In the example illustrated, the prop axis 132 of each prop 130 extends downwardly at an angle from the second end 136 (connected to the swivel connecter 128) to the first end 134 (connected to the base plate 122).

(22) Referring to FIG. 2, in the example illustrated, the swivel connectors 128 are pivotable relative to the wallform panel 104 for swinging the brace assembly 120 between a deployed position (shown in FIG. 2 in dashed lines—see also FIG. 1) and at least one storage position (shown in FIG. 2 in solid lines). In the example illustrated, when in the deployed position, the brace assembly 120 projects from the second side 114 of the wallform panel 104 for anchoring the base plate 122 to the ground surface 124 and supporting the wallform panel 104 upright (see also FIG. 1). When in the storage position, the brace assembly 120 lies adjacent the wallform panel 104, with the base plate 122 and props 130 adjacent the second side 114. In the example illustrated, when in the deployed position, the brace assembly 120 extends generally perpendicular to the wallform panel 104, and when in the storage position, the brace assembly 120 extends generally parallel with the wallform panel 104. Referring to FIG. 1, in the example illustrated, the swivel connectors 128 are pivotable about a vertical axis 138 relative to the wallform panel 104, and the props 130 (and base plate 122) are fixed to pivot with the swivel connectors 128 about the vertical axis 138 for swinging the brace assembly 120 between the deployed and storage positions. Referring to FIG. 2, in the example illustrated, the deployed position and the storage position are offset from each other by about 90 degrees about the vertical axis 138.

(23) Referring to FIG. 1, in the example illustrated, each prop 130 has a prop length measured along the prop axis 132 between the first end 134 and the second end 136 of the prop 130. In the example illustrated, the length of at least one of the props 130 is adjustable to facilitate alignment of the wallform panel 104 when the brace assembly 120 is anchored to the ground surface 124. In the example illustrated, each of the props 130 has an adjustable prop length, which can help provide for more flexibility in alignment of the wallform panel, for example, by allowing for more controlled translation and/or pivoting of the wallform panel when the base plate 122 is anchored.

(24) In the example illustrated, each prop 130 comprises a length adjustment mechanism 146 for adjusting the prop length. In the example illustrated, the length adjustment mechanism comprises a turnbuckle mechanism, which can allow for infinite adjustment of the prop length over an adjustment distance. In the example illustrated, the turnbuckle mechanism comprises a first rod 148 extending along the prop axis 132 from the first end 134 of the prop 130 to a threaded end of the first rod 148, a second rod 150 extending along the prop axis 132 from the second end 136 of the prop 130 to a threaded end of the second rod 150 having an opposite handedness relative to the threaded end of the first rod 148, and a turnbuckle frame 152 between and threadingly receiving the threaded ends of the first and second rods 148, 150 at opposite ends of the frame 152. The turnbuckle frame 152 is rotatable about the prop axis 132 relative to the threaded ends of the first and second rods 148, 150 to adjust a spacing therebetween for adjustment of the prop length.

(25) Referring to FIGS. 1A-1C, in the example illustrated, the first end 134 of each prop 130 is pivotably connected to the base plate 122 for pivoting about a corresponding first horizontal axis relative to the base plate 122, and the second end 136 of each prop 130 is pivotably connected to a corresponding swivel connector 128 for pivoting about a corresponding second horizontal axis relative to the swivel connector 128 to accommodate length adjustment of the props 130 for aligning the wallform panel 104.

(26) Referring to FIG. 1C, in the example illustrated, the first end 134 of each prop 130 is pivotably connected to the base plate 122 through a corresponding first horizontal pivot pin 158. In the example illustrated, the first end 134 of each prop 130 and the base plate 122 have complementary horizontal pinholes for receiving corresponding first pivot pins 158 (i.e. one pin 158a for pivotably connecting the upper prop 130a to the base plate 122, and one pin 158b for pivotably connecting the lower prop 130b to the base plate 122). In the example illustrated, each first pivot pin 158 is removable for disconnecting the first end 134 of the corresponding prop 130 from the base plate 122.

(27) Referring to FIGS. 1A and 1B, in the example illustrated, the second end 136 of each prop 130 is pivotably connected to a corresponding swivel connector 128 through a corresponding second horizontal pivot pin 160. In the example illustrated, each swivel connector 128 and corresponding second end 136 of each prop 130 include complementary horizontal pinholes 156a, 156b (FIG. 5), respectively, for receiving a corresponding pivot pin 160 (i.e. one pin 160a for pivotably connecting the upper prop 130a to the upper swivel connector 128a, and one pin 160b for pivotably connecting the lower prop 130b to the lower swivel connector 128b in the example illustrated). In the example illustrated, each second pivot pin 160 is removable for disconnecting the second end 136 of the prop 130 from the corresponding swivel connector 128.

(28) Referring to FIG. 3, in the example illustrated, each swivel connector 128 is pivotably connected to the wallform panel 104 through a vertical pivot pin 162 extending along the vertical axis 138 to facilitate pivoting of the swivel connector 128 (and brace assembly 120) about the vertical axis 138. In the example illustrated, a mount 164 is detachably secured (and fixed relative) to the frame 118 of the wallform panel 104, and the vertical pivot pin 162 passes through the swivel connector 128 and the mount 164 for pivotably connecting the swivel connector 128 to the wallform panel 104. In the example illustrated, each swivel connector 128 and corresponding mount 164 comprise complementary vertical pinholes 166a, 166b (FIG. 4), respectively, in alignment with the vertical axis 138 for receiving the vertical pivot pin 162.

(29) Referring to FIG. 2, in the example illustrated, the formwork system 100 includes a locking mechanism 170 operable to selectively lock the brace assembly 120 relative to the wallform panel 104 in at least one of the storage position and the deployed position, and to selectively unlock the brace assembly 120 relative to the wallform panel 104 for swinging between the deployed and storage positions. In the example illustrated, the locking mechanism 170 is operable to lock the brace assembly 120 in the deployed position and in the storage position relative to the wallform panel 104.

(30) In the example illustrated, the locking mechanism 170 is operable to lock the swivel connector 128 relative to the wallform panel 104 to inhibit pivoting of the swivel connector 128 (and the brace assembly 120) about the vertical axis 138 when the brace assembly 120 is in either of the deployed and storage positions. Referring to FIG. 2A, in the example illustrated, the locking mechanism 170 comprises a removable locking pin 172 (see also FIG. 3) insertable through a swivel aperture 174 (see also FIG. 3) in the swivel connector 128 and one of (i) a deployed-position aperture 176 fixed relative to the wallform panel 104 and in alignment with the swivel aperture 174 when the brace assembly 120 is in the deployed position, and (ii) at least one storage-position aperture 178 fixed relative to the wallform panel 104 and in alignment with the swivel aperture 174 when the brace assembly 120 is in the storage position (see also FIGS. 6 and 8).

(31) In the example illustrated, each of the swivel aperture 174, the deployed-position aperture 176, and the storage-position aperture 178 extends parallel with and is spaced horizontally apart from the vertical axis 138, and the storage-position aperture 178 is spaced apart from the deployed-position aperture 176 by about 90 degrees about the vertical axis 138. In the example illustrated, the deployed-position and storage-position apertures 176, 178 are provided in the mount 164, and the locking mechanism 170 is operable to selectively lock the swivel connector 128 relative to the mount 164 for inhibiting pivoting of the swivel connector 128 about the vertical axis 138 to lock the brace assembly in either the deployed or storage positions. In the example illustrated, the locking mechanism 170 has two storage-position apertures 178 spaced apart from each other about the vertical axis by about 180 degrees, so that the brace assembly 120 can be moved to and locked in either of two storage positions (i.e. a first storage position offset from the deployed position by about 90 degrees in a clockwise direction about the vertical axis 138, and a second storage position offset from the deployed position by about 90 degrees in a counter-clockwise direction about the vertical axis 138).

(32) Referring to FIGS. 8 and 9, in the example illustrated, the swivel connector 128 extends along a swivel connector axis 180 between a connector first end 182 and a connector second end 184 opposite the connector first end 182. In the example illustrated, the swivel connector 128 has a first joint portion 186 at the connector first end 182 for connection to the mount 164, and a second joint portion 188 at the connector second end 184 for connection to the second end 136 of the prop 130. In the example illustrated, the first and second joint portions 186, 188 are fixed to each other. In the example illustrated, the vertical pinhole 166a (for receiving the vertical pivot pin) and the swivel aperture 174 (for the locking mechanism) pass through the first joint portion 186 and are spaced apart from each other along the swivel connector axis 180. In the example illustrated, the horizontal pinhole 156a of the swivel connector 128 (for receiving the second pivot pin to pivotably connect the prop) passes through the second joint portion 188. In the example illustrated, the first joint portion 186 comprises a first knuckle joint, and the second joint portion 188 comprises a second knuckle joint offset from the first knuckle joint by 90 degrees about the swivel connector axis 180. In the example illustrated, each of the first knuckle joint and the second knuckle joint comprises a double knuckle joint. Referring to FIG. 2A, in the example illustrated, the second end 136 of each prop 130 comprises a single knuckle joint received in the second (double) knuckle joint of the swivel connector 128 for connection to the second knuckle joint through the pivot pin 160.

(33) Referring to FIGS. 6 and 7, in the example illustrated, the mount 164 extends along a mount axis 190 between a mount first end 192 and a mount second end 194. In the example illustrated, the mount 164 includes a pair of horizontal mount plates 196 spaced vertically apart by a plate spacing, and a cross plate 200 extending vertically between and connecting the mount plates 196. In the example illustrated, the cross plate 200 separates the plate spacing horizontally into a first channel 198a bounded vertically by a plate first portion 196a of the plates 196 and open to the mount first end 192, and a second channel 198b bounded vertically by a plate second portion 196b of the plates 196 and open to the mount second end 194.

(34) In the example illustrated, the first channel 198a is sized to receive a corresponding frame member 118a (FIG. 3) of the wallform frame 118 (FIG. 3) in close fit, and the plate first portion 196a has a pair of mounting holes 202 passing vertically therethrough for receiving corresponding mounting pins 204 (FIG. 3) for engagement with the frame member 118a to secure the mount 164 thereto. In the example illustrated, the mount 164 is adapted for mounting the swivel connector 128 to a horizontally extending frame member 118a of the frame 118. In other examples, the mount can be adapted for mounting the swivel connector 128 to vertically extending frame members of the frame 118.

(35) Referring to FIGS. 6 and 7, in the example illustrated, the vertical pinhole 166b passes through the plate second portion 196b. In the example illustrated, the second channel 198b is sized to receive the first joint portion 186 of the swivel connector 128 in close fit, with the vertical pinhole 166a of the swivel connector 128 in alignment with the vertical pinhole 166b of the mount 164 for receiving the vertical pivot pin 162 (FIG. 4). In the example illustrated, the deployed-position and storage-position apertures 176, 178 pass vertically through the plate second portion 196b.

(36) Referring to FIGS. 1-2, in use, the formwork system 100 is deployed by positioning the wallform panel 104 upright and swinging the brace assembly 120 from the storage position to the deployed position. Prior to swinging the brace assembly 120 to the deployed position, the brace assembly 120 is unlocked through operation of the locking mechanism 170 (e.g. the locking pin 172 is removed from the swivel aperture 174 and one of the storage-position apertures 178).

(37) When in the deployed position, the brace assembly 120 is locked relative to the wallform panel 104 through operation of the locking mechanism 170 (e.g. by inserting the locking pin 172 through the swivel aperture 174 and the deployed-position aperture 176), and the base plate 122 is anchored to the ground surface 124 using one or more anchors 126 (e.g. anchor bolts—FIG. 1C). When the base plate 122 is anchored, the prop length of at least one of the props 130 is adjusted to align the wallform panel 104.

(38) After alignment, and with the panels 104, 106 tied together, the building material (e.g. concrete) is poured into the space 110 between the panels 104, 106. When the building material is sufficiently cured, the formwork system 100 can be taken down. The take down process includes unanchoring the base plate 122 from the ground surface 124, unlocking the brace assembly 120 from the deployed position if previously locked (e.g. by removing the locking pin 172 from the swivel aperture 174 and the deployed-position aperture 176), and swinging the brace assembly 120 back to the storage position.

(39) When back in the storage position, the brace assembly 120 is locked relative to the wallform panel 104 (e.g. by inserting the locking pin 172 through the swivel aperture 174 and one of the storage-position apertures 178), and the formwork system 100 can be transported with the brace assembly 120 connected to the wallform panel 104 for storage or deployment at a different location to form another wall portion.

(40) When used for forming walls in a multi-level building, the formwork system 100 can be temporarily stored in a perimeter protection area of the multi-level building when not in use (e.g. stored adjacent perimeter protection panels outboard of the active construction area). During such storage, the brace assembly 120 can be locked in the storage position and remain connected to the wallform panel 104, allowing for more convenient transport to a different location (e.g. to another level of the building) and more rapid deployment and take down (e.g. by not necessarily requiring reconnection and disconnection of the brace assembly 120 to and from the wallform panel 104).
