Abstract
The invention involves a manner of fabricating 3D construction forms by preparing first and second standard sized panels with a predetermined pattern of perforations and assembling same in spaced apart relationship by connecting the panels together with connectors designed to engage the perforations in the panels. The perforations of the panels are arranged in a specific pattern suitable for the assembly and use of the construction forms by means of an apparatus designed to form the perforations. The method also uses apparatus which assist in the orientation and alignment of the connectors to engage the panels. Modifications of the panels and connectors will allow the formation of 3D construction forms with corners of various configuration.
Claims20
A method of fabricating 3D construction forms comprising the steps of:
- preparing a first standard size panel with a predetermined pattern of perforations;
- preparing a second standard size panel with a similar predetermined pattern of perforations;
- assembling said first and second panels in a fixed parallel spaced apart relationship by connecting said panels together with connectors designed to engage said perforations of respective panels.
Apparatus for forming a predetermined pattern of perforations in a panel of thermoplastic material comprising:
- a carriage mounted on tracks and adapted to travel in a first direction;
- a frame adapted to hold and support a said panel, said frame adapted to move on said carriage in a second direction perpendicular to said first direction;
- said first and second direction being parallel to the plane of said panel;
- a beam mounted to extend parallel to the plane of said panel and spaced in a direction perpendicular to said planar surface of said panel;
- at least one means mounted on said beam and capable of penetrating said panel to form a perforation therethrough;
- means to move said perforating means so as to engage said panel and to move said perforating means to disengage said panel.
Apparatus for the assembly of 3D construction forms having a first panel, a second panel, and a plurality of connectors having transverse rods joining said panels together in a spaced parallel relationship, said apparatus comprising:
- a stand;
- a frame mounted on said stand and adapted to hold in fixed position a first panel;
- a series of clamps associated with said frame adapted to hold a plurality of connectors in fixed position and orientation so that a first end of the transverse rods of said connectors are aligned with and engaged to the perforations of said panel.
A method of forming perforations in a panel of thermoplastic material comprising the steps of:
- heating an elongated tube to a temperature sufficient to melt said material without touching said material by heating the atmosphere surrounding said tube;
- advancing said tube toward said thermoplastic material at a rate sufficient to melt said material without touching it;
- proceeding to advance said tube until the material is perforated by the heated atmosphere surrounding said tube and then withdrawing said tube.
