A POLYFUNCTIONAL STRUCTURAL CONNECTOR used both as a wall connector and a vertical and horizontal structural element, in the prefabricated construction system registered under patent 002222-2015/DIN-INDECOPI.

This element, as a result of the dimensions thereof and the location of the holes thereof, may be used both as a wall connector and as a system structure. It is composed of a square-section tubular part, with pre-set holes to connect the different system elements of Patent 002222-2015/DIN-INDECOPI. This element is herein referred to as Polyfunctional Structural Connector.

The present application is directed toward fire-rated wall construction components and wall systems for use in building construction. Embodiments can include tracks for holding studs which incorporate various geometries capable of receiving fire-retardant material, flat straps for use between tracks and fluted wall components, fire sponges for use in fluted wall components, and tracks with protruding grooves or other structures which prevent unwanted air movement between a wallboard component and the track.

A one-piece stud has a central longitudinal side; a first longitudinal side joined at a 90? angle to the first end of the central longitudinal side; and a second longitudinal side joined at a 90? angle to the second end of the central longitudinal side. The central side has a first and a second planar surface joined by an acute isosceles triangular channel midway between. The first longitudinal side is formed of a third and a fourth planar surface joined by an acute isosceles triangular channel midway between. The second longitudinal side has a fifth and a sixth planar surface joined by an acute isosceles triangular channel midway between. At an end opposite the 90? joint, the first longitudinal side and the second longitudinal side have free ends each forming a gapped right isosceles triangle. The longitudinal channels increase the axial capacity and the moment capacity of the stud.

A frame design and a sheathing design for a design model may be produced by the systems and methods described herein. A processor in communication with a database may receive a design model comprising building specifications. The processor may define a panel in the design model and generate the frame design and the sheathing design for the panel.

A wall or ceiling panel, which, on one side edge, comprises a male coupling part and, on an opposite side edge, comprises a female coupling part. The male coupling part comprises a tongue and the female coupling part comprises a groove. The groove is bordered by a front lip and a rear lip, with the characteristic that the panel forms a ceiling-high wall panel and/or has a length of at least 2400 mm.
