Total Claims: 8
Claim 1
Independent Claim
262 words
In a concrete wall form of the type wherein opposed form sides, each consisting of panel units disposed in edge-to-edge relationship, are reinforced by outside, spaced apart, vertical strongbacks, wherein adjacent strongbacks on each form side are bridged and connected by reaction washers through which tie rod-connected she-bolts having externally threaded outer end regions loosely project, wherein fastening nuts are threadedly received on the outer threaded ends of the she-bolts so as to resist the outward spreading action of the washers incident to the outward thrust of wet concrete which is poured between the form sides, and wherein means are provided on said washers for releasably clamping said washers to their respective pairs of strongbacks, the improvement which comprises: a clip member of inverted J-shape configuration having a relatively short inner leg and a relatively long outer leg connected together at their upper ends by a bight portion associated with each she-bolt, and means captively and pivotally connecting said clip member at the inner leg thereof to the associated reaction washer for swinging movement of the clip member between a lowered vertical locking position wherein said legs straddle the adjacent nut and washer with the outer leg opposing the outer face of the nut, captively locating said nut between said washer and the inner face of the outer leg, and an out-of-the-way raised upwardly inclined position wherein a major portion of the clip member is disposed between and straddled by the adjacent strongbacks and the outer leg is withdrawn from the nut in order to render the latter accessible for wrench-receiving purposes.

In a concrete wall form of the type wherein opposed form sides, each consisting of panel units disposed in edge-to-edge relationship, are reinforced by outside, spaced apart, vertical strongbacks, wherein adjacent strongbacks on each form side are bridged and connected by reaction washers through which tie rod-connected she-bolts having externally threaded outer end regions loosely project, wherein fastening nuts are threadedly received on the outer threaded ends of the she-bolts so as to resist the outward spreading action of the washers incident to the outward thrust of wet concrete which is poured between the form sides, and wherein means are provided on said washers for releasably clamping said washers to their respective pairs of strongbacks, the improvement which comprises: a clip member of inverted J-shape configuration having a relatively short inner leg and a relatively long outer leg connected together at their upper ends by a bight portion associated with each she-bolt, and means captively and pivotally connecting said clip member at the inner leg thereof to the associated reaction washer for swinging movement of the clip member between a lowered vertical locking position wherein said legs straddle the adjacent nut and washer with the outer leg opposing the outer face of the nut, captively locating said nut between said washer and the inner face of the outer leg, and an out-of-the-way raised upwardly inclined position wherein a major portion of the clip member is disposed between and straddled by the adjacent strongbacks and the outer leg is withdrawn from the nut in order to render the latter accessible for wrench-receiving purposes.
Claim 3
Dependent Claim
66 words
That improvement in a concrete wall form as set forth in claim 1 and wherein the distal lower end region of said outer leg of the clip member has formed therein a clearance notch which straddles the outer end of the externally-threaded region of the associated she-bolt in close proximity to the outer face of said nut when the clip member is in its locking position.
Claim 4
Dependent Claim
61 words
That improvement in a concrete wall form as set forth in claim 2 and wherein the inner leg of the clip member has formed therein an elongated vertical slot through which extends loosely a guide member which projects inwardly from the peripheral region of the washer and by means of which such leg is slidingly and pivotally connected to the washer.
Claim 5
Dependent Claim
52 words
That improvement in a concrete wall form as set forth in claim 3 and wherein the guide member is in the form of a small block which projects through the slot, and trunnion-like pins are provided on the block for capturing the inner leg of the member in position on the washer.
Claim 6
Dependent Claim
40 words
That improvement in a concrete wall form as set forth in claim 4 and wherein the distal end of the inner leg is turned laterally outwardly to provide a limit stop for the upward sliding movement of the clip member.
Claim 7
Dependent Claim
37 words
That improvement in a concrete wall form as set forth in claim 5 and wherein the slot in the inner leg of the clip member projects a slight distance into said laterally-turned distal end of such leg.
Claim 8
Dependent Claim
32 words
That improvement in a concrete wall form as set forth in claim 6 and wherein said block is fastened to the peripheral region of the washer by means of a fastening screw.
