Abstract
A method for casting hollow core concrete panels includes the use of raft connectors to hold a plurality of spaced foam billets in place during the manufacture to create panel or plank with spaced foam-filled cores.
Claims8
A raft connector for connecting a plurality of foam billets together for use in forming concrete panels, the raft connectors comprising:
- (a) a cross-bar;
- (b) a pair of spaced angled members descending downwardly from said cross-bar;
- and
- (c) at least one downwardly projecting member for insertion and holding in a foam billet.
A raft connector for connecting a plurality of billets together for use in forming hollow core concrete panels, the raft connectors comprising:
- (a) a cross-bar;
- and
- (b) at least two pairs of spaced downwardly extending projections, each pair being spaced apart the width of a billet to be used, each pair being spaced from the adjacent pair.
A method for forming concrete panels comprising the steps of:
- (a) arranging a plurality of prestressing cables within a casting bed having a bottom pallet and side walls;
- (b) casting a first layer of concrete on said bed;
- (c) placing billets on top of said cast concrete layer between said prestressing cables;
- (d) interconnecting said billets into a raft of billets;
- (e) casting a top layer of concrete over said billets;
- and
- (f) curing said concrete.
A method for forming concrete panels comprising the steps of:
- (a) arranging a plurality of prestressing cables within a casting bed having a bottom pallet and side walls;
- (b) casting a first layer of concrete on said bed;
- (c) interconnecting billets into a raft of billets;
- (d) placing said interconnected billets on top of said cast concrete layer between said prestressing cables;
- (e) casting a top layer of concrete over said billets;
- and
- (f) curing said concrete.
A hollow core concrete panel comprising:
- a) a lower layer of concrete;
- b) a plurality of interconnected, spaced billets above said lower layer of concrete;
- and
- c) an upper layer of concrete surrounding said interconnected billets and being bonded to said lower layer of concrete.
A hollow core concrete panel comprising:
- a) a lower layer of concrete;
- b) a plurality of prestressed cables extending the length of said panel;
- c) a plurality of interconnected, spaced billets above said lower layer of concrete;
- and
- d) an upper layer of concrete surrounding said interconnected billets and being bonded to said lower layer of concrete
