| One inch threaded rod runs entire width of several tubes under building. Nuts crank and hold modular units together. | Inventor, Gary Murray, holding patented bolt-up sleeve used to help align and strengthen sump floor joint between modular units. | Bolt-up sleeve partially inserted into the tube under floor of rear modular unit. Coupler connects threaded rods from both units. | Exterior wall mid joint caulked down to base. Bolt-up sleeve (arrow) hidden between each module. |
Hazmat building modular components protected by U.S. Patent numbers 5,191,742 (1993), 5,285,617 (1994) and 5,396, 742 (1995).
Flexibility - Flexibility - Haz-Safe Modular buildings were invented in 1991 to permit very large buildings to be "modularized" into several units for shipping purposes and then be bolted together on site. Some Haz-Safe modular projects are small enough to be bolted together at the factory and shipped, then be expanded in the future. All Haz-Safe Modular Buildings are pre-approved by Factory Mutual.
Modular building with 3 bolt-up base tubes under the floor. Arrow points to sleeve (see photos at top of page). Roof top and floor joints are capped against leaks. Wall and ceiling joints have 1, 2, or 4 HRFR covers. Plan #7 on right shows initial building for 20 drums and future expansion for 44 drums.
Clear span up to 48' provides large column free space. Half on left is complete while half on right shows exposed 2"' thick Thermafiber foil back insulation (R15) yet to be covered with porcelain enamel steel on fire rated gypsum. Plan #8 shows space filled with 2', 3', and 4' wide shelving. |
Patented Technology comes into action when bolting the modules together. First, the roof top crane lifting lugs allow the units to be easily brought together to within inches of each other. Slings (as used by others) are not in the way between modules because they are not coming down from unneeded spreader bars. Next, 1" diameter nuts (at the ends of threaded rods within several 4" x 4" steel tubes welded under each unit's floor) are cranked to bring the units together. On the roof, pairs of lifting lugs are used for bolting purposes. A cap is put over the joints on the roof and the interior sump floor. The exterior wall joint is weather caulked and the interior wall and ceiling joints are fire caulked and covered with fire rated gypsum.
