Abstract
A bracing system for a concrete form includes at least one spacer holding and spanning opposing sides of the form, and at least one inclined strut. The strut, at its upper end, attaches to the spacer and, at its lower end, engages the ground. The strut lower end has a spike and a foot plate for driving the spike into the ground by the user's weight. Preferably, two struts are employed, one on either side of the form. Both attach to the same spacer by dowel sockets and dowel pins. Each strut prevents the form from collapsing on its respective side. Each strut is independently adjustable as to length due to telescoping members having aligned holes, and is locked at a desired length by a spring loaded, captively retained pin. The bracing system is quickly and easily assembled by hand, and is retained in place by pins secured by clips.
Claims8
A bracing system for concrete forms having opposed vertical form boards, said bracing system including:
- at least one inclined brace having an upper and a lower end and comprising telescoping inner and outer struts,
- one of said inner and outer struts having means defining at least one first hole, and the other of said inner and outer struts having means defining a plurality of second holes, said first and second holes selectively aligning, said inclined brace also including a pin corresponding in cross sectional configuration to said first and second holes, whereby said pin is inserted through one said first hole and one said second hole, said inclined brace being adjusted as to length thereby,
- one of said inner and outer struts engaging the ground and including a foot having a foot plate and a spike penetrating the ground, whereby said foot anchors said inclined brace in the ground,
- the other of said inner and outer struts including strut attachment means secured thereto at said upper end and anchoring at the concrete form, and
- at least one spacer having opposing sides and comprising two pairs of parallel walls for surroundingly engaging, respectively, opposed form boards, and two spacer attachment means cooperating with and attaching to said strut attachment means, whereby said spacer holds two form boards in parallel, spaced apart relation and secures one said upper end of one said inclined brace on one side of said spacer and secures another said upper end of another said inclined brace to an opposed side of said spacer, while said one inclined brace is also secured at said lower end by penetrating the ground, whereby said bracing system, when assembled, is braced against collapse in opposing directions,
- said strut attachment means comprising a first dowel socket, and said spacer attachment means comprising a second dowel socket, said first and second dowel sockets aligning with one another when said strut and said spacer are in operative positions with respect to an assembled concrete form, said strut attachment means further comprising a dowel which is placed in and unites said strut attachment means and said spacer attachment means, said dowel having means defining a radial bore therein, there further being a clip which is manually inserted into and withdrawn withdrawn from said bore, and
- said outer strut further having means captively retaining said pin and a spring biasing said pin into an operative position.
A bracing system for concrete forms having two opposed vertical form boards, said bracing system including:
- at least one inclined brace having an upper and a lower end and comprising telescoping inner and outer struts,
- one of said inner and outer struts having means defining at least one first hole, and the other of said inner and outer struts having means defining a plurality of second holes, said first and second holes selectively aligning, said inclined brace also including a pin corresponding in cross sectional configuration to said first and second holes, whereby said pin is inserted through one said first hole and one said second hole, said inclined brace being adjusted as to length thereby,
- one of said inner and outer struts engaging the ground and including a foot having a foot plate and a spike penetrating the ground, whereby said foot anchors said inclined brace in the ground,
- the other of said inner and outer struts including strut attachment means secured thereto at said upper end and anchoring at the concrete form,
- at least one attachment means cooperating with and attaching to said strut attachment means, and attaching to a concrete form, whereby said at least one inclined brace is removably attached to the concrete form, thus constraining the concrete form against collapse, and
- at least one spacer comprising two pairs of parallel walls for surroundingly engaging, respectively, opposed form boards, said at least one attachment means cooperating with and attaching to said strut attachment means, whereby said spacer holds two form boards in parallel, spaced apart relation and secures said upper end of one said inclined brace, while said one inclined brace is also secured at said lower end by penetrating the ground.
