Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
275 words
In a concrete wall form, in combination, front and rear opposed upstanding spaced apart sides each of which is comprised of a series of individual upstanding panels disposed in edge-toedge relationship, each panel including a rectangular facing and a rectangular marginal reinforcing frame including vertical side members, each panel having one of the vertical side members of its frame abutting a vertical side member of the frame of an adjacent panel, there being a hole in each of the abutting side members at substantially the same height in the wall form whereby the holes are in registry, a waler board positioned horizontally against the front side of the form and bearing against the outer edges of a pair of the abutting vertical side members in bridging relationship, and a waler clamp assembly for clamping the waler board hard against said outer edges of said pair of abutting side members, said waler clamp assembly comprising a U-shaped bracket having upper and lower horizontal legs and a connecting bight portion, the distal end of the upper leg being provided with a reentrant hook which projects through the registering holes in said pair of abutting side members, the distal end of the lower leg effectively bearing against said outer edges of the last mentioned vertical side members, there being aligned openings in said legs near the base portions thereof, and a tapered wedge projecting vertically through said aligned openings and bearing at its inner side against the outer side of the waler board, said wedge exerting a spreading action against the outer edge of the opening in said upper leg and the outer side of the waler board.
Claim 2
Dependent Claim
275 words
In a concrete wall form, in combination, front and rear opposed upstanding spaced apart sides each of which is comprised of a series of individual upstanding panels disposed in edge-toedge relationship, each panel including a rectangular facing and a rectangular marginal reinforcing frame including vertical side members, each panel having one of the vertical side members of its frame abutting a vertical side member of the frame of an adjacent panel, there being a hole in each of the abutting side members at substantially the same height in the wall form whereby the holes are in registry, a waler board positioned horizontally against the front side of the form and bearing against the outer edges of a pair of the abutting vertical side members in bridging relationship, and a waler clamp assembly for clamping the waler board hard against said outer edges of said pair of abutting side members, said waler clamp assembly comprising a U-shaped bracket having upper and lower horizontal legs and a connecting bight portion, the distal end of the upper leg being provided with a reentrant hook which projects through the registering holes in said pair of abutting side members, the distal end of the lower leg effectively bearing against said outer edges of the last mentioned vertical side members, there being aligned openings in said legs near the base portions thereof, and a tapered wedge projecting vertically through said aligned openings and bearing at its inner side against the outer side of the waler board, said wedge exerting a spreading action against the outer edge of the opening in said upper leg and the outer side of the waler board.
Claim 3
Dependent Claim
98 words
In a concrete wall form, the combination set forth in claim 1 and including, additionally, a horizontal tie rod having one end thereof secured to the rear side of the form, spanning the distance between said form sides, and having its other end region projecting outwardly of the form beyond the general plane of the facings of the panels of the front side of the form, said other end region of the tie rod having an opening therethrough in register with the registering holes in said pair of abutting side members and through which said reentrant hook projects.
Claim 4
Dependent Claim
35 words
In a concrete wall form, the combination set forth in claim 2 and wherein said other end of the tie rod is interposed between the vertical side members of said pair of abutting side members.
Claim 5
Dependent Claim
58 words
In a concrete wall form, the combination set forth in claim 1 and wherein said reentrant hook is provided with an inclined cam surface which bears against an edge of one of the registering holes in said pair of abutting side members for drawing said side members together under the influence of the spreading action of the wedge.
Claim 6
Dependent Claim
72 words
In a concrete wall form, the combination set forth in claim 1 and including, additionally, a thrust plate slidable on the lower leg of the U-shaped bracket, having its forward end overhanging the distal edge of the latter and its rear end overhanging the forward edge of the the opening in the lower leg, said thrust plate being engageable with said wedge and being subject to the spreading action of the latter.
Claim 7
Dependent Claim
41 words
In a concrete wall form, the combination set forth in claim 5 and wherein the forward edge of the thrust plate is formed with a downturned bearing flange which abuts against the outer edges of said pair of abutting side members.
Claim 8
Dependent Claim
82 words
In a concrete wall form installation, the combination set forth in claim 1 and including, additionally, a second waler board positioned horizontally against the front side of the form, bearing against the outer edges of said pair of abutting side members in bridging relationship and spaced beneath said first mentioned waler board, said latter waler board effectively resting on the lower leg of the bracket and being confined between said wedge and the outer edges of said pair of abutting side members.
