Gutter expansion joint
View Patent ↗A gutter expansion joint includes a first metal sheet, a second metal sheet and a roof membrane strip. A thermoplastic polyolefin coating is applied to one side of the first and second metal sheets. A first end of the roof membrane strip overlaps the first metal sheet and is secured to the first metal. A second end of the roof membrane strip overlaps the second metal sheet and is secured to the second metal sheet. The first metal sheet, the roof membrane strip and the second metal sheet are bent to be received by an inner perimeter of two adjacent gutters. A bead of non-curing sealant is applied to an inside surface of the two adjacent gutters, before insertion of the gutter expansion joint. A gutter expansion joint cover is attached to an outside perimeter of the two adjacent gutters.
1. A method of inserting an expansion joint between a first gutter section and a second gutter section, comprising the steps of:
providing a first metal sheet having a thermoplastic polyolefin coating applied to a first side thereof;
providing a second metal sheet having a thermoplastic polyolefin coating applied to a first side thereof;
providing a roof membrane strip fabricated from a thermoplastic polyolefin material;
overlapping said first metal sheet on said first side with a first portion of said roof membrane strip, overlapping said second metal sheet on said first side with a second portion of said roof membrane strip;
heating a junction of said first metal sheet and said roof membrane strip, such that a bond is formed between said first metal sheet and said roof membrane strip; and
heating a junction of said second metal sheet and said roof membrane strip, such that a bond is formed between said second metal sheet and said roof membrane strip to form a gutter expansion joint
inserting a first end of the gutter expansion joint into an inner perimeter of the first gutter section, inserting a second end of said gutter expansion joint into the second gutter second.
2. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 1 , further comprising the step of:
utilizing hot air for heating said first metal sheet, said roof membrane strip and said second metal sheet.
3. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 1 , further comprising the step of:
said first and second metal sheets are fabricated from a steel sheet with a galvanized metal coating.
4. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 1 , further comprising the step of
providing said gutter expansion joint with an inside vertical wall, a horizontal wall, an angled wall, an outside vertical wall and a horizontal inward facing flange.
5. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 1 , further comprising the step of:
covering the first gutter section, said gutter expansion joint and the second gutter section with a gutter expansion joint cover.
6. A method of inserting an expansion joint between a first gutter section and a second gutter section, comprising the steps of:
providing a first metal sheet having a thermoplastic polyolefin coating applied to a first side thereof;
providing a second metal sheet having a thermoplastic polyolefin coating applied to a first side thereof;
providing a roof membrane strip fabricated from a thermoplastic polyolefin material;
overlapping said first metal sheet on said first side with a first portion of said roof membrane strip, overlapping said second metal sheet on said first side with a second portion of said roof membrane strip;
heating a junction of said first metal sheet and said roof membrane strip, such that a bond is formed between said first metal sheet and said roof membrane strip;
heating a junction of said second metal sheet and said roof membrane strip, such that a bond is formed between said second metal sheet and said roof membrane strip; and
bending said first metal sheet, said second metal sheet and said roof membrane strip to have a cross sectional shape which sized to be received by an inner perimeter of the first and second gutter sections to form a gutter expansion joint
inserting a first end of said gutter expansion joint into an inner perimeter of the first gutter section, inserting a second end of said gutter expansion joint into the second gutter section.
7. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 6 , further comprising the step of:
utilizing hot air for heating said first metal sheet, said roof membrane strip and said second metal sheet.
8. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 6 , further comprising the step of:
said first and second metal sheets are fabricated from a steel sheet with a galvanized metal coating.
9. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 6 , further comprising the step of:
providing said gutter expansion joint with an inside vertical wall, a horizontal wall, an angled wall, an outside vertical wall and a horizontal inward facing flange.
10. The method of inserting an expansion joint between a first gutter section and a second gutter section of claim 6 , further comprising the step of:
covering the first gutter section, said gutter expansion joint and the second gutter section with a gutter expansion joint cover.
