Abstract

An isolation block is useful for sealing a flute of a fluted metal deck and a movement joint between the metal deck and an adjacent wall configuration. The isolation block includes a flute sealing portion adapted to snugly fit into one of the flutes of the fluted metal deck, a joint sealing portion for sealing a movement joint, and a corrugation sealing portion for sealing a corrugation between adjacent fluted deck elements or in one of the fluted deck elements.

First claim

The invention claimed is:

1. An isolation block for sealing a flute of a fluted metal deck and a movement joint between the metal deck and an adjacent wall configuration,
the isolation block comprising
a flute sealing portion having a shape corresponding with a shape of fluted deck corrugation to fit into one of the flutes of the fluted metal deck,
a joint sealing portion adapted to seal a movement joint, and
a corrugation sealing portion having a generally triangular cross section when seen in mounted state along a horizontal axis adapted to seal a corrugation between adjacent fluted deck elements or in one of the fluted deck elements.

2. The isolation block of claim 1 , wherein
the flute sealing portion has a generally trapezoid cross section when seen in mounted state along a horizontal axis,
wherein a top surface and two side surfaces of the flute sealing portion are adapted to be compressed against a corresponding wall section of one of the flutes respectively, and
wherein a bottom surface of the flute sealing portion, being opposed to the top surface, is substantially parallel to the top surface.

3. The isolation block of claim 2 , wherein
the joint sealing portion has a substantially rectangular cross section, when seen in mounted state along the horizontal axis, and
is attached to the bottom surface of the flute sealing portion.

4. The isolation block of claim 3 , wherein
the joint sealing portion is shorter than the flute sealing portion in a direction along the horizontal axis and protrudes over the flute sealing portion on at least one side, when seen in cross section.

5. The isolation block of claim 1 , wherein
the corrugation sealing portion is attached to the portion of the joint sealing portion protruding over the flute sealing portion, and
wherein the corrugation sealing portion and the flute sealing portion are attached on the same side of the joint sealing portion.

6. The isolation block of claim 1 , which is produced as one integral part.

7. A method for sealing a flute of a fluted metal deck and a movement joint between the metal deck and an adjacent wall configuration wherein a wall plane of the wall configuration is positioned substantially perpendicular to a flute axis 44 and wherein the wall configuration comprises a ceiling runner being mounted on a lower side of the fluted metal deck, the method comprising the following steps:
a) plugging one or more isolation blocks of claim 1 into a gap between the ceiling runner and the deck and
b) subsequently mounting one or more gypsum boards.

8. The method of claim 7 , wherein
the gypsum board is flapped into the wall plane during step b) and compresses at least a portion of the isolation block into the wall plane.

9. The method of claim 7 , wherein
the gypsum board is brought into the wall plane during step b) and subsequently is slid towards the fluted deck, and
wherein the gypsum board compresses at least a portion of the isolation block against the fluted deck.

10. The method of claim 7 , wherein
the isolation block comprises at least one reinforcement element of which at least a portion protrudes from the isolation block, and
wherein the protruding portion of the reinforcement element is brought into engagement with the wall configuration by compressing the isolation block during step b.

11. A wall and deck configuration,
comprising a fluted metal deck and a wall configuration, wherein
a wall plane of the wall configuration is positioned substantially perpendicular to a flute axis of the fluted metal deck, and
wherein at least one isolation block of claim 1 is positioned between the fluted metal deck and the wall configuration, thereby sealing at least one flute of the fluted metal deck and a movement joint between the metal deck and an adjacent wall configuration.
