Abstract

A method includes coupling a platform to a sheet metal having alternating peaks and Valleys. The platform includes a block-out component configured to conform to a valley of the sheet metal. The method further includes coupling a lead-sleeve to a mounting region of the platform. The method further includes pouring concrete around the platform and lead-sleeve, where the block-out component blocks a flow of the concrete from below the platform. The method also includes inserting a cutting tool through the lead-sleeve to remove one or more portions of the sheet metal to form a through-penetration.

First claim

The invention claimed is:

1. A method, comprising:
coupling a platform to a sheet metal comprising alternating peaks and valleys, wherein the platform comprises a block-out component configured to conform to a valley of the sheet metal;
coupling a lead-sleeve to a mounting region of the platform;
pouring concrete around the platform and lead-sleeve, wherein the block-out component blocks a flow of the concrete from below the platform; and
inserting a cutting tool through the lead-sleeve to remove one or more portions of the sheet metal and the block-out component to form a through-penetration through the sheet metal.

2. The method of claim 1 , comprising inserting a tubular conduit through the through-penetration.

3. The method of claim 1 , comprising inserting a protective sleeve into the lead-sleeve.

4. The method of claim 3 , wherein inserting the cutting tool through the lead-sleeve comprises inserting the cutting tool through the protective sleeve of the lead- sleeve.

5. The method of claim 1 , wherein coupling the platform to the sheet metal comprises securing one or more flanges of the platform to one or more grooves of the sheet metal.

6. The method of claim 1 , wherein coupling the platform to the sheet metal comprises positioning the mounting region of the platform across a peak and a valley of the sheet metal.

7. The method of claim 1 , wherein coupling the platform to the sheet metal comprises positioning the mounting region of the platform across a valley of the sheet metal.

8. The method of claim 1 , wherein the block-out component comprises two parallel components having a chamber therebetween.

9. The method of claim 8 , wherein the chamber is below the mounting region of the platform.

10. The method of claim 8 , wherein the two parallel components conform to a floor of the valley of the sheet metal to prevent the flow of concrete into the space.

11. The method of claim 8 , wherein the two parallel components conform to angled walls of the valley of the sheet metal to prevent the flow of concrete into the space.

12. A method, comprising:
coupling a platform to a sheet metal comprising alternating peaks and valleys, wherein the platform comprises a block-out component configured to conform to a valley of the sheet metal:
coupling a lead-sleeve to a mounting region of the platform;
pouring concrete around the platform and lead-sleeve, wherein the block-out component blocks a flow of the concrete from below the platform and
inserting a cutting tool through the lead-sleeve to remove one or more portions of the sheet metal to form a through-penetration through the sheet metal, including creating an opening through the platform.
