Method for splicing stress skins used for manufacturing structural insulated panels
View Patent ↗A method for manufacturing substantially longer structural insulated panels through lamination without sacrificing thermal efficiency and structural integrity. The method includes laminating an insulating structure in between a lower sheet of serial panels and an upper sheet of serial panels. The individual structural panels of the lower sheet of serial panels are spliced together with a plurality of lower splice plates. Similarly, the individual structural panels of the upper sheet of serial panels are spliced together with a plurality of upper splice plates. The plurality of upper splice plates is positioned offset from the plurality of lower splice plates. The resulting elongated structural insulated panel retains its characteristics due to the positioning of the splice plates and their integration into the manufacturing method.
1. A manufacturing method for splicing stress skins comprises the steps of:
(A) providing a lower sheet of serial panels, an upper sheet of serial panels, a plurality of lower splice plates, a plurality of upper splice plates, and an insulating structure;
(B) laying the lower sheet of serial panels onto an assembly platform;
(C) interspersedly mounting the plurality of lower splice plates along the lower sheet of serial panels at a first interval, wherein the first interval is defined by divisions amongst the lower sheet of serial panels;
(D) mounting the insulating structure onto the plurality of lower splice plates and the lower sheet of serial panels;
(E) interspersedly mounting the plurality of upper splice plates along the insulating structure at a second interval, wherein the second interval is offset from the first interval;
(F) aligning divisions amongst the upper sheet of serial panels to the plurality of upper splice plates;
(G) mounting the upper sheet of serial panels onto the plurality of upper splice plates and the insulating structure; and
(H) executing a curing process in order to create a structural insulated panel from the lower sheet of serial panels, the upper sheet of serial panels, the plurality of lower splice plates, the plurality of upper splice plates, and the insulating structure;
wherein each of the plurality of upper splice plates and each of the plurality of lower splice plates is made of a carbon fiber-reinforced polymer; each of the plurality of upper splice plates and each of the plurality of lower splice plates is made of a phenolic resin material; the upper sheet of serial panels and the lower sheet of serial panels are of equal length and equal width; and the insulating structure is made of an expanded polystyrene foam.
2. The method for splicing stress skins as claimed in claim 1 further comprises the steps of:
applying a first adhesive layer in between steps (B) and (C).
3. The method for splicing stress skins as claimed in claim 1 further comprises the steps of:
applying a second adhesive layer in between steps (C) and (D).
4. The method for splicing stress skins as claimed in claim 1 further comprises the steps of:
applying a third adhesive layer in between steps (D) and (E).
5. The method for splicing stress skins as claimed in claim 1 further comprises the steps of:
applying a fourth adhesive layer in between steps (F) and (G).
6. The method for splicing stress skins as claimed in claim 1 further comprises the steps of:
providing a hydraulic press for the curing process;
inserting the lower sheet of serial panels, the upper sheet of serial panels, the plurality of lower splice plates, the plurality of upper splice plates, and the insulating structure into the hydraulic press; and
applying uniform pressure across the upper sheet of serial panels for a required time by actuating the hydraulic press.
