A building joint is a junction where building elements meet without applying a static load from one element to another. When one or more of these vertical or horizontal elements that meet are required by the local building code to have a fire-resistance rating, the resulting opening that makes up the joint must be firestopped in order to restore the required compartmentalisation.
Blocks and building system for the construction of lifesize inflatable play structures
A system for the construction of life size play structures includes a multiplicity of inflatable building blocks, each being a member of a finite set of different multi-sided block types. Each such type is a cylinder having the cross section of a regular polyhedron, and the length of each side of each polyhedron is identical. The blocks are attached to each other by means of a rotating joint which aligns each contiguous side of each block with the contiguous side of the adjoining block, but which does not allow each such to translate relative to the adjoining block. The joints are constructed at fixed locations along the sides according to specific dimensional ratios. Stiffening means are used to maintain the dimensional integrity of each block, and to maintain the uniformity of the system from block to block.

Method and apparatus for deflecting liquid from a foundation wall
InactiveUS20070175113A1Easy to moveAddressing Insufficient CoverageProtective foundationBuilding constructionsStructural engineeringBasement floor
Rain water is deflected from the foundation wall of a building structure by a flashing of non-ferrous metal that is fastened to the foundation below the grade level of the soil. Soil is trenched and exposed about the foundation. Multiple sections of foundation flashing are installed in the trench around the perimeter of the foundation wall. Adjacent flashing sections overlap in a continuous manner. After installation, the trench is backfilled with soil thereby covering the flashing and restoring grade. During heavy rains or floods, water seeping into the soil is deflected away from the foundation by the flashing. This prevents water from pooling at the bottom of the foundation and seeping up into the structure through the joint where the foundation meets the basement floor.
