Abstract
Abstract Panel pads are provided which are useful in spacing concrete panels and the like for purposes of curing, storage, packing and shipping. The pad construction consists of a plurality of pad bases connected together by parallel straps in serial alignment, the bases being provided on one side thereof with a plurality of hemispherical projections peaking in a common plane and arranged in three parallel rows, the projections in the outer rows of which are aligned with each other and are equally spaced. The projections in the innermost of the three rows are staggered with respect to the projections in the outer rows and are divided into two groups of three projections each on each respective pad base. These groups are spaced to leave a gap therebetween. Each base is provided with at least one hole passing therethrough which permits affixing the pads to wooden supports or the like. The bases are scored so that they may be hingeably displaced into separate sections or so that they can be broken apart to form separate sections.

Claim 3
Dependent Claim
21 words
A construction as claimed in claim 1 wherein said projections are aligned in parallel but staggered rows in each said base.
Claim 4
Dependent Claim
17 words
A construction as claimed in claim 2 wherein said base is provided with a hole passing therethrough.
Claim 5
Dependent Claim
17 words
A construction as claimed in claim 3 wherein each said base is rectangularly shaped with rounded corners.
Claim 6
Dependent Claim
19 words
A construction as claimed in claim 4 wherein the projections extend about three times the thickness of the base.
Claim 7
Dependent Claim
23 words
A construction as claimed in claim 5 wherein said base has a substantially constant thickness of about 1/16 to 3/8 of an inch.
Claim 8
Dependent Claim
58 words
A construction as claimed in claim 6 wherein the projections are arranged in three parallel rows the outer two of which include six evenly spaced mutually aligned projections and the inner row of which includes six projections arranged in two spaced groups of three projections each of which are staggered relative to the projections of the outer rows.
Claim 9
Dependent Claim
19 words
A construction as claimed in claim 7 wherein the projections are spaced by at least one-eighth of an inch.
Claim 10
Dependent Claim
103 words
A panel pad construction comprising base means having opposite sides and, on one of said sides, a plurality of spaced solid and substantially non-deformable hemispherical projections of equal height peaking at points in a common plane, said base means including a plurality of bases, each said base forming a monolithic structure with respective of said projections, each said base being provided with a scoring serving selectively to divide the same into hingeably connected sections adapted to be broken into separate sections each of which has projections thereon, said monolithic structure being of a high density polyethylene having a specific gravity of about 0.92-0.95.
