A trim structure intended on one hand to receive a door, in particular an internal door, and on the other hand to be joined to a partition. The structure includes two lateral wails facing one another and spaced apart by a thickness. The thickness being adjusted with respect to the thickness of the partition such the lateral walls form an external surface that is flush with the external surface of the partition. when the structure is joined to the partition. A transverse end wall connects the two lateral walls. The transverse end wall includes a planar surface that is configured to butt up against the thickness of a vertical edge face of the door and a projecting element (15) forming a bearing surface for the door. The walls being formed from at least one composite panel, the panel comprising a central layer sandwiched between two facing layers.

A method and a precast building component and window frame system. The method comprising: positioning a window frame within a window opening of a precast building component, wherein the precast building component comprises solidified settable material; forming a void between the window frame and the precast building component, wherein the void surrounds the window frame; wherein barrier material is placed within the gap between opposing surfaces of the window frame and the precast building component to form a boundary of the void; filling the void with a settable adhesive sealant; wherein the settable adhesive sealant, once set, provides a continuous seal that surrounds the window frame and supports the window frame within the window opening.

A new prefabricated wall panel is the basic unit of a new, more efficient and stronger wall system. The wall panel is manufactured from a plurality of foam sections sized to leave vertical and horizontal voids into which concrete is later poured, each foam section having an inner and outer surface and two sides; and a plurality of fastening strips. The fastening strips are longitudinal metal strips being situated between the sides of two foam sections. Each fastening strip has two longitudinal fastening strips projecting perpendicularly to the longitudinal fastening strip and the fastening strips being adjacent to the outer surface of the two foam sections. The fastening strip also has a plurality of clearance holes in the longitudinal fastening strip, a plurality of embed tabs projecting from the edge opposite the fastening strips, each embed tab having at least one hole, and between each pair of embed tabs, a foam tab to hold the two inner sides of the foam sections in place and partially separate the foam sections from the concrete to be poured into a form.

Various devices, assemblies, components, systems, and methods are provided relating to a framing system. An example framing system may include a lower frame assembly, an upper frame assembly, and side frame assemblies. The framing system may be secured to a portion of a concrete wall while the wall is still partially wet to create a seal between the wall and the system. The lower frame assembly, the upper frame assembly, and the side frame assembly may be configured to assist with the installation of an object (e.g., a window, a door, etc.) within a precast concrete wall (e.g., sandwich wall, etc.) and/or architectural cladding element.
