Abstract

Abstract The invention relates to an apparatus utilized in the pouring of concrete walls and includes a number of vertical girder-like or "strong-back" members to which are clamped a number of transversely extending beam members having wooden inserts to which plywood panels are nailed, the arrangement constituting a form. In use, a pair of such forms are spaced apart by tie rods extending from one form to the other form and concrete is poured between the facing plywood panels. Selected of the strong-back members may be provided with brackets which assist in ensuring that the form is in correct vertical alignment to the ground and other brackets may be provided to cooperate with the strong-back members in order to support a walkway and a safety-fence.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 321 words
A form utilized in the pouring of concrete walls, said form including: (a) a plurality of spaced parallel profiled primary strongback members, each said strongback member including an elongated web having opposed upper and lower longitudinal edges, a pair of lower flanges connected to and extending from the lower longitudinal edge of said web, an upwardly extending stub flange connected to the edge of each said lower flange most distant from said web, a pair of upper flanges connected to and extending from the upper edge of said web, and a downwardly extending stub flange connected to the edge of each said upper flange most distant from said web; (b) a plurality of spaced parallel profiled structural members, each said structural member including an elongated web having upper and lower longitudinal edges, a pair of lower flanges connected to the lower longitudinal edge of said web and being configured to accept a lumber insert therebetween, a pair of upper flanges connected to and extending from the upper edge of said web, at least one downwardly extending stub flange connected to the edge of one said lower flange most distant from said web, and a lumber insert disposed intermediate the lower flanges of said structural member; (c) a plurality of clamp members detachably engageable with said stub flanges of adjacent strongback lower flanges and structural member upper flanges to maintain said strongback and structural members normal to one another; (d) a plurality of plywood panels detachably secured to said lumber inserts; and (e) a plurality of tie plates and cooperating tie bolts detachably secured to the stub flanges of the upper flanges on said strongback members, said tie bolts extending through said plywood panels; said form being capable of connection to, but spaced from, a complementary form whereby each said form can be efficiently assembled so that concrete can be poured between the pair of forms to produce a poured concrete wall.
Claim 2
Dependent Claim 321 words
A form utilized in the pouring of concrete walls, said form including: (a) a plurality of spaced parallel profiled primary strongback members, each said strongback member including an elongated web having opposed upper and lower longitudinal edges, a pair of lower flanges connected to and extending from the lower longitudinal edge of said web, an upwardly extending stub flange connected to the edge of each said lower flange most distant from said web, a pair of upper flanges connected to and extending from the upper edge of said web, and a downwardly extending stub flange connected to the edge of each said upper flange most distant from said web; (b) a plurality of spaced parallel profiled structural members, each said structural member including an elongated web having upper and lower longitudinal edges, a pair of lower flanges connected to the lower longitudinal edge of said web and being configured to accept a lumber insert therebetween, a pair of upper flanges connected to and extending from the upper edge of said web, at least one downwardly extending stub flange connected to the edge of one said lower flange most distant from said web, and a lumber insert disposed intermediate the lower flanges of said structural member; (c) a plurality of clamp members detachably engageable with said stub flanges of adjacent strongback lower flanges and structural member upper flanges to maintain said strongback and structural members normal to one another; (d) a plurality of plywood panels detachably secured to said lumber inserts; and (e) a plurality of tie plates and cooperating tie bolts detachably secured to the stub flanges of the upper flanges on said strongback members, said tie bolts extending through said plywood panels; said form being capable of connection to, but spaced from, a complementary form whereby each said form can be efficiently assembled so that concrete can be poured between the pair of forms to produce a poured concrete wall.
Claim 3
Dependent Claim 20 words
Apparatus according to claim 1 including combined plumbing and support means detachably secured to selected ones of said strongback members.
Claim 4
Dependent Claim 26 words
Apparatus according to claim 2 including bracket means detachably secured to the stub flanges of certain of said strongback members and adapted to support a walk-way.
Claim 5
Dependent Claim 25 words
Apparatus according to claim 3 wherein said bracket means has upright post members detachably secured thereto and serving to support a safety fence extending therebetween.
Claim 6
Dependent Claim 25 words
Apparatus according to claim 4 wherein additional strongback members are detachably secured to one end of each of selected ones of said primary strongback members.
Claim 7
Dependent Claim 82 words
Apparatus according to claim 5 including brackets detachably secured within said additional strongback members and having projecting means adapted to cooperate and interlock with detents projecting from the previously poured and set section of a concrete wall whereby the form can be positioned in vertical operative alignment with said section, said brackets also having screw means adapted to vary the vertical alignment of the form in relation to said previously poured section and prior to the pouring of the next succeeding section.
Claim 8
Dependent Claim 34 words
Apparatus according to claim 6 including closure members detachably secured to each of said primary strongback members, certain of said closure members being provided with means whereby said form can be raised and lowered.
