The invention is a mixed stucco block of gypsum blocks. Due to using a layer of compacted polystyrene in its center, it is much lighter than regular gypsum blocks. In addition, its heat transfer coefficient is less than solid stucco panels. In addition, due to applying some smithereens in it along with support system and innovative Rabyts, mechanical connection of cement mortar is provided for it. Therefore it is possible to use this block in wet places including in bathroom, WC, and as the side wall of the faade.

Rebar-based support assemblies that can be fabricated without the need for on-site welding. The assemblies include a number of differing sized and shaped crimps used in place of welds to provide rebar assembly-to-rebar assembly connections. In some examples, a crimp for mechanically joining rebar for use in a support system for a physical structure includes a body with at least two recessed surfaces each configured for receiving a respective first and second piece of rebar; and a pair of spaced-apart arms at least partially enclosing an interior space of the body including the at least two recessed surfaces, a first tip and a second tip of the respective spaced-apart arms each defining a respective first and second opening to the interior space, in a first configuration.

A self-aligning corner bead for fireproofing structural steel, having a strip of welded wire fabric cut to the appropriate width for the fireproofing thickness and bent longitudinally to form an obtuse V-shaped device is disclosed. A plastic nosing is installed along one edge. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the first wing of an obtuse V-shaped device through a lathe to the structural steel member utilizing pneumatic or screw type fasteners. The mesh structure of the second wing of the V-shaped device provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.

A self-aligning, double wire corner bead for fireproofing structural steel along a plurality of surfaces, the corner bead having a single strip of welded wire fabric cut to a predetermined width for the fireproofing thickness and bent along a plurality of longitudinally extending lines, to provide a profile having a plurality of dihedral angles is disclosed. A nose is installed along two edges. A method of finishing the corners for fireproofing of structural steel member using an improved corner bead includes the step of attaching the corner bead through a lath to the structural steel member utilizing fasteners. The mesh of the corner bead provides a dam to form a roughened surface on the first application of fireproofing material until it hardens.

The present invention relates to a method for replacing a conventional mold construction, and includes a plate-shaped outer insulating material, an inner plywood (or a board-shaped finishing material), a connection unit, and a lightweight temporary material. According to the present invention, a wall is constructed by connecting the inner plywood to the lightweight temporary material from a corner foundation surface and by laying bricks. Reinforcement bars are placed after an interior wall is constructed and arranged to cross each other or to alien with each other as instructed in a design specification. Then, an exterior wall is installed corresponding to the connection unit connected to the inner plywood. As a result, a wall having a thermal bridge prevention effect and a higher quality is obtained. Either dry finish or a wet finish is applicable to the wall.

An improved lath is disclosed having a water drainage layer provided in association with the lath. The water drainage layer serves to remove water that might otherwise build up between the lath and wall structure.

A laminated board is secured to the inner wall of a cavity wall construction to establish a defined spacing between the inner and outer walls and prevent excess mortar from bridging to the inner wall. The laminated board has a series of spaced sockets into which fasteners may project into the face of the inner wall or framing thereof to secure the outer wall. The board is installed prior to the construction of the outer wall and establishes a minimum spacing or gap between the walls based upon the thickness of the board. The outer wall is constructed immediately adjacent to the outer face of the laminated board. The board is impervious and eliminates bridging by the mortar, eliminates transfer of bulk water from the exterior finish to the inner wall and provides an air conduit to exhaust even the minimal amounts of vapor that will occur in the cavity.

A dry wall tape for use with a panel system includes a mesh having a plurality of width strands, and a plurality of length strands which traverse the plurality of width strands, wherein the length strands are more resistant to a pulling force than the width strands and wherein the tape is configured to be applied to the panel system.

A metal lath accessory comprising a metal lath attachment feature that includes a side wall, a first flange extending from the side wall, and a second flange extending from the side wall. The first flange comprises at least one barb that projects from the first flange towards the second flange. In some embodiments, the second flange comprises at least one barb that projects from the second flange toward the first flange. The barbs may be configured to engage a piece of metal lath that is inserted between the first flange and the second flange.
