Abstract
Abstract A concrete casting assembly including at least one battery of Ltype mould members preferably with an overhead gantry providing a chute of rectangular C-shape which can be located over different mould spaces of the battery. The mould members are arranged in the battery one within the other so as to have the adjacent edges of the adjacent arms of the mould members alined with one another in respective mutually orthogonal planes each inclined by an angle of 45* to the plane containing the corner edges of the mould members. The mould members are preferably of steel construction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
269 words
A concrete casting assembly including a battery for casting concrete panels, the battery comprising: a plurality of adjacent mould members each having two mutually orthogonal arm portions presenting substantially vertical mould faces with one portion being of longer length in plan than the other arm portion, the arms of each mould member being smaller than the adjacent arms of the preceding adjacent mould member so that said mould members are adapted to be arranged one within the other with the adjacent and edges of the adjacent arms of the mould members aligned with one another in one of two respective mutually orthogonal planes each inclined at an angle of 45* to the plane containing the corner edges of the mould members, said assembly when viewed in plan comprises a battery of L-shaped members and a battery of reversed L-shaped members, first arm portions comprising the longer arm portions in one battery being arranged to lie substantially in common planes with the corresponding arm portions in the other battery, and second arm portions comprising the shorter arm portions in both said batteries being arranged to lie parallel to one another and on the same side of the particular common plane containing their associated first arm portions further including an overhead gantry comprising a rectangular C-shaped leading chute for the introduction of material into either of the two mould batteries, and drive means for moving the gantry over the upper surfaces of the mould batteries in directions parallel to the plane containing the corner edges of the mould members to align the loading chute with a mould space in the batteries.

A concrete casting assembly including a battery for casting concrete panels, the battery comprising: a plurality of adjacent mould members each having two mutually orthogonal arm portions presenting substantially vertical mould faces with one portion being of longer length in plan than the other arm portion, the arms of each mould member being smaller than the adjacent arms of the preceding adjacent mould member so that said mould members are adapted to be arranged one within the other with the adjacent and edges of the adjacent arms of the mould members aligned with one another in one of two respective mutually orthogonal planes each inclined at an angle of 45* to the plane containing the corner edges of the mould members, said assembly when viewed in plan comprises a battery of L-shaped members and a battery of reversed L-shaped members, first arm portions comprising the longer arm portions in one battery being arranged to lie substantially in common planes with the corresponding arm portions in the other battery, and second arm portions comprising the shorter arm portions in both said batteries being arranged to lie parallel to one another and on the same side of the particular common plane containing their associated first arm portions further including an overhead gantry comprising a rectangular C-shaped leading chute for the introduction of material into either of the two mould batteries, and drive means for moving the gantry over the upper surfaces of the mould batteries in directions parallel to the plane containing the corner edges of the mould members to align the loading chute with a mould space in the batteries.
Claim 3
Dependent Claim
36 words
An assembly as claimed in claim 1 including lifting rams adapted to be mounted over said chute, and means adapted to extend through said chute for connecting said rams with a mould member of the battery.
Claim 4
Dependent Claim
247 words
A concrete casting assembly including a battery for casting concrete panels, the battery comprising a plurality of adjacent mould members each having two mutually orthogonal arm portions presenting substantially vertical mould faces, the arms of each mould member being smaller than the adjacent arms of the preceding adjacent mould member so that said mould members are adapted to be arranged one within the other with the adjacent end edges of the adjacent arms of the mould members aligned with one another in one of two respective mutually orthogonal planes each inclined at an angle of 45* to the plan containing the corner edges of the mould members and a rectangular C-shaped loading chute for introducing material into either of the two mould batteries and drive means for moving the chute over the upper surfaces of the mould batteries in directions parallel to the plane containing the corner edges of the mould members to align the chute with a mould space in the batteries, said assembly when viewed in plan comprising a battery of L-shaped members and a battery of reversed L-shaped members, first arm portions comprising the longer arm portions in one battery being arranged to lie substantially in common planes with the corresponding arm portions in the other battery, and second arm portions comprising the shorter arm portions in both said batteries being arranged to lie parallel to one another and on the same side of the particular common plane containing their associated first arm portions.
Claim 5
Dependent Claim
247 words
A concrete casting assembly including a battery for casting concrete panels, the battery comprising a plurality of adjacent mould members each having two mutually orthogonal arm portions presenting substantially vertical mould faces, the arms of each mould member being smaller than the adjacent arms of the preceding adjacent mould member so that said mould members are adapted to be arranged one within the other with the adjacent end edges of the adjacent arms of the mould members aligned with one another in one of two respective mutually orthogonal planes each inclined at an angle of 45* to the plan containing the corner edges of the mould members and a rectangular C-shaped loading chute for introducing material into either of the two mould batteries and drive means for moving the chute over the upper surfaces of the mould batteries in directions parallel to the plane containing the corner edges of the mould members to align the chute with a mould space in the batteries, said assembly when viewed in plan comprising a battery of L-shaped members and a battery of reversed L-shaped members, first arm portions comprising the longer arm portions in one battery being arranged to lie substantially in common planes with the corresponding arm portions in the other battery, and second arm portions comprising the shorter arm portions in both said batteries being arranged to lie parallel to one another and on the same side of the particular common plane containing their associated first arm portions.
Claim 6
Dependent Claim
20 words
An assembly as claimed in claim 3 in which the mould members include ducting for steam heating the mould members.
Claim 7
Dependent Claim
45 words
An assembly as claimed in claim 3 in which the mould members are associated with adjustable end-stops delimiting the narrow vertical surfaces of the mould spaces, ram means being provided for adjusting the position of said stops to provide a mould space of predetermined size.
Claim 8
Dependent Claim
47 words
An assembly as claimed in claim 3 in which the mould members are associated with baseboards providing the bottom surfaces of tHe mould spaces, said baseboards providing means for altering the vertical width of the mould spaces by choosing an appropriate baseboard assembly for that mould space.
