A concrete building block includes indicators along each end to assist in aligning a pin placed in the block with a channel in a like block in a course below as a wall is being constructed.

The present disclosure generally pertains to blocks for building landscape walls and similar structures, the molds used to make the blocks, and the methods for making the blocks. Such block can be securely coupled to another block. A block can be vertically coupled to another block by coupling the dorsal face of one block to the ventral face of another block. The block can be horizontally coupled by coupling the male side of one block to the female side of another block. A secure, exemplary landscape wall may be created by coupling the blocks both horizontally and vertically to reach a desired height, width, and shape.

A block, block system and method of making a wall block. Multiple block embodiments with multiple embodiments of a visually exposed surface having three dimensional shaped areas and three dimensional angular valleys or joints that can be used to construct a patio, wall, fence or the like; the multiple embodiments creating a more random and natural appearance.

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 system for building a wall includes a plurality of blocks and a plurality of connectors for aligning the blocks in successive courses. Each block has opposing first and second surfaces bounded by opposing front and rear faces and opposing end faces, the first and second surfaces being profiled with respective first and second rectilinear channels extending parallel to the front and rear faces. Each connector has first and second portions profiled for reception in respective first and second channels, the first portion being profiled to slide but not rotate in the first channel, the second portion being profiled to slide and rotate in the second channel. The second portion is offset from the first portion so that two different orientations of two blocks placed against each other are possible. The blocks preferably have a trapezoidal shape cut with only straight cuts to facilitate using natural stone.

A wall block having a block body and a vertical plane of symmetry. The block body having a front portion, a rear portion and a neck portion. The wall block including a core extending through the neck portion and dividing the neck portion into first and second neck wall members extending rearward from the front portion to the rear portion. The wall block having a flange extending downward from the block body. The wall block having a channel positioned in the rear portion of the block body. The wall block having a first plane parallel to the plane of symmetry that passes through the first neck wall member and a second plane parallel to the plane of symmetry that passes through the second neck wall member, the first and second planes being located approximately midway between the plane of symmetry and the lateral outermost points of the wall block.

A dovetailed building block includes a block body having a plurality of side surfaces. The side surfaces are constructed in an order of having a side surface with a dovetailed recess next to another surface with a dovetailed projection. The dovetailed projection of one said block body can engage the corresponding dovetailed recess of another said block body in a 90-degree cross manner. Thereupon, while in stacking a plurality of the block bodies, variety of secured and stable three-dimensional curved configuration can be built through angular engagement of one dovetailed projection of one block body and another dovetailed recess of another block body.

A pure wood connection structure, having pure wood units, self tapping screws, a first pure wood edge sealing unit and a second pure wood edge sealing unit; an upper side and a lower side of each pure wood unit are provided respectively with a contraction slit, and are applied with wood adhesives; in each pure wood unit, the self tapping screws are screwed into the pure wood unit from the contraction slit on the upper side, through the contraction slit on the lower side, and down into the upper side of an adjacent pure wood unit, so that the upper side of each pure wood unit is connected with the lower side of a corresponding adjacent pure wood unit; all the pure wood units are likewise mutually connected one adjacent to another to form a board structure.
