A method for constructing a three-dimensional (3D) printer-printable wall system includes forming a concrete foundation on a substrate, where the concrete foundation embeds horizontal and vertical reinforcements. A first inner wythe horizontal layer and a first outer wythe horizontal layer are printed using a concrete mixture from a 3D printer. The first inner wythe horizontal layer and the first outer wythe horizontal layer are separated by an interstitial space. A first wall dam is placed between the first inner wythe horizontal layer and the first outer wythe horizontal layer in the interstitial space. Additional inner wythe horizontal layers are printed on top of the first inner wythe horizontal layer to form a composite inner wythe. Additional outer wythe horizontal layers are printed on top of the first outer wythe horizontal layer to form a composite outer wythe. At least one additional wall dam is placed on every horizontal layer, while a wall tie and an attachment bracket for utility lines are placed only on pre-defined intervals of horizontal layers of the composite inner wythe and the composite outer wythe, which are separated by the interstitial space. A sill cap is installed on top of the composite inner wythe and the composite outer wythe, where the sill cap comprises a first curb to encapsulate a top portion of the composite inner wythe, a second curb to encapsulate a top portion of the composite outer wythe, and a central trough positioned between the first curb and the second curb. An anchor mechanism is inserted into the sill cap.

A retrofit brick tie comprises an elongate member having a first end and a second end. The first end includes a first aperture and a second aperture. Each of the first and second apertures is configured and arranged to receive a fastener. The second end includes a first elongated opening and a second elongated opening. Each of the first and second elongated openings is configured and arranged to receive an adhesive. A method of installing the retrofit brick tie comprises creating a bore in an interior surface of a brick structure, filling the bore with an adhesive, and inserting the second end into the bore. A stud is positioned proximate the interior surface, and a fastener is inserted through each of the first and second apertures and into the stud thereby securing the stud to the brick structure.

A support assembly supports external veneer such as face-brick. A bracket mounts to a load bearing wall support structure. A shelf angle includes a horizontal leg that defines a surface upon which to mount the veneer. The mounting bracket may be a channel having a seat that includes an outwardly protruding toe, an accommodation for the shelf angle, and an overhanging finger. The back of the shelf angle may have apertures to admit the toes of the mounting bracket. The seat includes an oversized slot having a relief angle to permit the shelf angle web to be rotated angularly during assembly. The mounting bracket has an overhanging arm for engaging the part of a cross-wise running beam, such as an I-beam upper flange. The mounting bracket has an abutment for contacting a lower part of the beam, such as a lower flange of an I-beam. There is a fitting to secure the bracket to the beam.

A system and method for a wall anchor including a washer for use in a cavity wall to connect to a veneer tie that joins an inner wythe and an outer wythe of the cavity wall are disclosed. The washer includes an opening configured to receive a shaft associated with the wall anchor, a washer body first side configured to abut one or more surfaces associated with the inner wythe, a washer body second side, and a washer body side wall. The washer body having at least one receiving element, including at least one receiving element opening configured to receive a portion of the veneer tie.

The present invention is an assembly-type brick set. More specifically, the present invention is an assembly-type brick set which not only maximizes structural rigidity and fastening performance but is also able to, by excluding use of brittle bonding agent such as concrete mortar, prevent damage and collapse of a wall even in cases of severe shaking, such as during earthquakes.

This assembly-type brick set comprises a brick portion in which is formed at least one brick hole which penetrates a brick body vertically, and a joint which is inserted into the brick hole, wherein: the brick hole is formed in the shape of an hour glass wherein the diameter of a middle portion is smaller than a top diameter and a bottom diameter; the joint is formed so that its top portion fits into the bottom of the brick hole, and its bottom portion fits into the top of the brick hole; a plurality of brick portions is provided stacked vertically adjacent to each other; and, an assembled brick structure is achieved by inserting the joint between the adjacently stacked brick portions.

A printed wall stabilizing assembly includes an elongated member having a first end and a second end. The elongated member has a first bend and a second bend therein such that the elongated member is generally U-shaped and defines a bracket. A first arm is defined from the first bend to the first end and a second arm is defined between the second bend and the second end. A central section is defined extending between the first and second arms. The first and second arms lie a same plane as the central section. The elongated member is comprised of a material is resistant to the corrosive effects of water and has low thermal conductivity. The central section positioned in a first wall of a pair of walls such that the first and second arms extend into a second wall of the pair of walls.
