Abstract
The present invention resides in a wall unit and formulation which is particularly advantageous for the manufacture of prefabricated buildings. The wall unit uses a uniquely formulated exterior wall panel that is bonded to a frame of tri-chord steel beams. The unique cementitious composition of the wall unit allows it to be fire and insect resistant and generally impervious to moisture.
Claims9
A structure, comprising:
- a cementitious panel;
- a frame of steel beams having opposed triangular end portions;
- and
- cementitious bonding pads that attach the frame, at one of the triangular end portions of the steel beans, to the panel.
A cementitious panel composition comprising (by weight) at least 25% cement, less than 55% sand, less than 5% glass fibers, at least 1.6% acrylic polymer, and at least 11% water.
A cementitious panel composition comprising (by weight) about 40.3% cement, about 40.3% sand, about 2.9% glass fibers, about 4.0% acrylic polymer, about 0.4% super plasticizer and about 12.1% water.
