## Abstract

An Interlocking Stackable Modular Building Block plastic molded container is disclosed that is ideally suited for making barrier walls, slabs and emergency living quarters. The referred embodiment of the Block is a hollow container with extrusion tongue on the one end and insertion groove on the other end. The Blocks can be placed adjacent to each other in interlocking position by inserting the tongue of the first Block in to the groove of the adjacent Block. Blocks have narrow ledge on the top and wider extension on the bottom. The wider bottom fits snugly on the top narrow ledge when Blocks are placed on top of each other and are held tight with screws. Walls and slabs can be made out of Blocks when they are placed in adjacent interlocked position and stacked top and bottom position. Such walls and slabs are ideally suited for providing winterized insulated housing to people in remote areas and areas that are hit with natural calamities such as earthquakes and floods. The walls are also suitable for erecting barriers alongside of freeways to reduce traffic noise. The Blocks are lightweight and inexpensive as they are manufactured with plastic molded material.

## Claims

### Claim 1

A modular Building Block providing capability of making walls, slabs and living quarters by placing them in interlocked position end to end and stacked position top and bottom. The Building Blocks are containers measuring 2 ft.×1 ft.×3 in., lightweight and made out of plastic molding material that require no cement or glue to hold them together. The front of the Block has an extrusion tongue and back of the Block has a grooved insertion. Several of them can be held in interlocked position by inserting the tongue of the one Block in to the groove the adjacent Block. Blocks are provided with narrow ledge on the topside and wide extension on the bottom side, so they can be placed snugly on top of each other for making walls and slabs. Blocks can be held tight with screws when they are placed on top of each other.
