A multi-use block including a block body having at least a first leg. The blocks can be placed in different orientations with respect to each other to form multiple interlocking structures. The block can be a variety of materials, including concrete, and when concrete, used for making walls and columns. Methods of making and methods of use are provided.

A block is disclosed that includes a top surface, a bottom surface, a pair of sidewalls, and a pair of endwalls. The block also includes a projection that protrudes beyond the top surface along a first axis and is symmetrical along a second axis and a third axis. The block also includes a recess that extends into the bottom surface along the first axis and is symmetrical along the second axis and the third axis. The block also includes a pair of trenches including a first trench and a second trench that are respectively defined by a recess extending into an endwall of the pair of endwalls. The pair of trenches both run along the first axis from a surface of the projection to a surface of the recess, and a first width of the first trench overlaps with a second width of the second trench along the third axis.

A method of engineering monolithic earthen masonry consists of selecting sufficient amount of subsoil mixture and straws, wherein physical characteristics of the subsoil mixture are determined from a sieve analysis test and a hydrometer analysis. The proper mixing ratios of the subsoil mixture and the straws provide a composite sample. The composite sample is then dried and lastly exposed to a compressive test. If optimal plurality of particle size percentage distributions within the subsoil mixture is not obtainable due to lack of resources, the end-product of the non-ideal subsoil mixture is adjusted within the aforementioned method or thickness and/or height of a building to compensate for the load-bearing capacities of the building.

Provided is an assemblable wood brick. A unit of wood brick is composed of five plates including a top plate, two opposite first lateral plates and two opposite second lateral plates. Dovetail tenons, dovetail sluts, sluts and protrusions are correspondingly defined on sides each of the five plates such that the five plates are securely and orthogonally connect to each other at their sides to form a brick unit having a space defined there-inside. In addition, blind hole(s) can be provided on the outer surface of each one of the five plates such that any two brick can stably connect to each other by a fixed member corresponding to and engaging into the holes. Several types of furniture and constructions can be formed by connecting suitable amount of the bricks. Further, blind holes can be defined on both top side and bottom side of the second lateral plates such that any two bricks can stably connect to each other by a fixed member corresponding to and engaging into the holes.

A room divider device is comprised of foam panels, supporting poles with extenders and hinges, horizontal tracks, and vertical joiners for creating wall to divide the floor space. The supporting poles are assembled with pole sections and extender accommodating height and slope of ceiling. The swivel hinges are allowing the dividers to be built according to variety of existing wall and ceiling configurations. The foam panels are laid down and connected with the interlocking parts of horizontal tracks and vertical joiners. The grooves on the panels fit to the extruded bars inside of tracks and maintain the position of the panels. The swivel hinges provide the options for connecting walls up to three with various angles from sixty to three hundred degrees. Two different sizes of panels are stacked alternately to build stable and strong walls.
