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 spliced wall panel comprises at least one layer of frame bodies stacked in sequence; the frame body is formed by splicing several boards sequentially, and buckles are provided at the joint of adjacent boards; inclined structures are oppositely arranged on both sides of the board, and a positioning protrusion and a positioning groove that fit each other are formed on the oppositely arranged inclined structures respectively; a horizontal mounting groove is formed on the top of the inner wall of the board, and a mating groove matching the mounting groove is formed on the outer wall at the bottom of the board; fitting blocks that match the buckles are formed on both sides of the outer wall of the board. The frame structure formed from multiple boards meets the requirements of the wall panel and can be stacked into a multi-layer frame structure based on actual needs.

An insulation product may include an insulation material. The insulation material may include at least one material selected from the group consisting of nonwoven insulation, aerogel insulation, mineral insulation, and foam insulation. The insulation material may include a first end and a second end positioned opposite the first end. The first end may include a protrusion. At least a portion of the protrusion may widen in a direction opposite the second end. The second end may define a cutout that substantially matches a size and shape of the protrusion. The cutout and the protrusion may be aligned with one another along a length of the insulation material.

A concrete block includes first, second, third, fourth, fifth, and sixth planar faces. The first and second faces are generally parallel, and the distance between the first and second faces define a thickness of the first block; the third and fourth faces are parallel to each other and perpendicular to the first and second faces; the fifth face is perpendicular to the first, second, third, and fourth faces; the sixth face: extends perpendicular to the third face; extends toward the fourth face and ends at a non-planar remainder section; is parallel to the fifth face; is contained in a plane that intersects a plane containing the third face; and a distance from the intersection to the remainder section is at least as long as the thickness of the first block; and the remainder section extends between the sixth face and the fourth face and has a shape such that when a second block of the same construction as the first block has its remainder section engaged against the remainder section of first block, the remainder sections of the first and second blocks mate.

A system for building a load bearing structure for supporting a compressive load, the system including a plurality of wooden members; wherein a protrusion of a second member is locatable within a recess of a first or third member to interconnect the first and second or third and second members together to form the loading bearing structure, wherein the protrusion is not rotatable within the recess, and; wherein the third member has a recess with a depth greater than the height of the protrusion of the second member such that a cavity is formed between an upper inner wall of the third member and a top portion of the protrusion of the second member when the second and third members are interconnected.

A stub-up is provided for being anchored to concrete slab flooring in which conduit is embedded and through which electrical wiring may be extended. The stub-up comprises a one-piece hollow body having an upper end providing an electrical box and a lower end providing a base permitting the hollow body to be anchored to an underlying concrete slab in an upstanding position. The hollow body provides a wireway for electrical wiring from the slab to the electrical box. Wall structures and methods are also disclosed.

A wall assembly is manufactured for supporting an exterior covering of a structure. The wall assembly includes a frame assembly including a top member and a bottom member spaced from the top member. The frame assembly further includes a plurality of vertical members spaced from each other and coupled to and extending between the top and bottom members. The plurality of vertical members each have an exterior surface configured to face an exterior of the structure. A rigid foam layer is directly coupled to the exterior surface of the plurality of vertical members. A sheathing layer is coupled to the rigid foam layer opposite the plurality of vertical members with the sheathing layer configured to receive the exterior covering.

An exterior insulation structure includes a first board member, first supporting members, a first thermal insulator, second supporting members disposed on the exterior side of the first supporting members, a second thermal insulator disposed on the exterior side of the first thermal insulator and between the second supporting members, securing members fixed to the exterior side of the second supporting members, and exterior wall members attached to the securing members. The adjacent exterior wall members are joined together without leaving a gap therebetween. Each securing member is long enough, in the second direction, to be fixable to at least two second supporting members and shorter, in the second direction, than each exterior wall member. A first gap is left between the securing members adjacent in the second direction. At least part of each second supporting member is made of a material having a thermal conductivity lower than that of steel.
