An intruder resistant screen providing improved strength. The improved intruder resistant screen comprises a frame, a woven wire intruder resistant mesh covering an opening enclosed by the frame, a plurality of clamp elements engaging with frame members to hold the mesh by a leveraged clamping action and at least one fastener holding each clamping member to the frame member. Each fastener has a drilling portion, a shank portion, a head and a thread. The frame comprises multiple frame members joined by corner stakes and there are two or more clamp elements engaging each frame member.

A bracket for connecting a first extruded member having spaced and generally parallel extrusion fins to a second member. The bracket comprising a base plate, a longitudinal wedge element configured to be inserted in between the extrusion fins, an extrusion fin receiving channel to receive a first extrusion fin of the first extruded member, fastener receiving apertures through the base plate to receive a fastener to rigidly couple the bracket to the first extruded member, and a deformation cavity adjacent the fastener receiving aperture configured to receive a deformed extrusion portion of the first extrusion fin. The fastener receiving aperture is located on the base plate such that the deformed extrusion portion is forced into the deformation cavity and at least partially out of the extrusion fin receiving channel to form a rigid connection in a deformed condition when a fastener is located in the fastener receiving aperture.

A connecting fitting (20A) for connecting two construction materials includes a first connecting member (21) and a second connecting member (22) for connecting the construction materials, and a parallelizing means (45) having a parallelizing function of aligning the connecting members (21, 22) in a first direction and making them parallel or almost parallel to each other. The first direction is a direction perpendicular to both the direction (M) of an interval between the two construction materials and the thickness direction of one construction material. The parallelizing function of the parallelizing means (45) disappears due to a load caused to act on at least one of the connecting members (21, 22). The inclination angles of the connecting members (21, 22) with respect to the direction (M) of the interval become inclination angles (θ1, θ2) opposite to each other due to the disappearance of the parallelizing function. This makes it possible to effectively perform the work for connecting two construction materials arranged with an interval therebetween even when this interval is small, and render one construction material immobile with respect to the other construction material after the connecting work.

Window lite assemblies and methods for installing the assemblies are provided herein. The assemblies described herein are configured to be installed in new and existing buildings, especially in building corners, while leaving some or all of the horizontal structural members such as headers and sills in place.

A main tilting door for the closure of an access opening of a room comprises two fixed uprights and one fixed crosspiece associable with each other to define a fixed frame. The fixed uprights comprise vertical sliding guides; two movable uprights and two movable crosspieces associable with each other to define a movable frame; tilting movement means comprising: two lateral supporting arms each having a first end which can be hinged to an intermediate area of the movable uprights and a second end which can be hinged to a top of the fixed uprights; two sliding supports movable along the vertical sliding guides; a plurality of panels associable with the movable frame; wherein at least one of said movable uprights and said movable crosspieces comprises a sliding track and a plurality of cursors movable along the sliding track, the panels being associable with the cursors.

An intruder resistant screen providing improved strength. The improved intruder resistant screen comprises a frame, a woven wire intruder resistant mesh covering an opening enclosed by the frame, a plurality of clamp elements engaging with frame members to hold the mesh by a leveraged clamping action and at least one fastener holding each clamping member to the frame member. Each fastener has a drilling portion, a shank portion, a head and a thread. The frame comprises multiple frame members joined by corner stakes and there are two or more clamp elements engaging each frame member.

The present disclosure relates generally to acoustic panels, for example, suitable for acoustic ceiling surfaces. The present disclosure relates more particularly to acoustic panels that include a panel body (e.g., comprising fiberglass, or having an NRC value in the range of at least 0.5, e.g., 0.5-0.95 or 0.5-0.9) and a perimeter frame extending around a side edge of the panel body. The perimeter frame includes a plurality of frame members including a first frame member and a second frame member. A first adhesive bonds the frame members to the panel body. A second adhesive with a shorter working time may also bond the frame members to the panel body. In addition, or alternatively, a bracket that couples the frame members to one another includes a sharp projection that hinders removal of the bracket from the frame members once assembled. These aspects allow the acoustic panel to be handled before the first adhesive is cured.

A modular glass door assembly includes a door, an inner frame, and an outer frame. The door has a glass door leaf and a doorframe mounted to the outer periphery of the glass door leaf. The inner frame is attached to the outer periphery of the doorframe and connected to the doorframe by two hinges up and down. The outer frame has four frame strips arranged around the outer periphery of the inner frame and each provided with a concave portion engaged with one respective convex portion of the inner frame. By this way, the inner frame and the outer frame can be directly assembled with each other or a fixed window panel can be added between the inner frame and the outer frame. Thus, the modular glass door assembly of the present invention has advantages of easy assembly and high scalability.

A polymer window assembly includes a polymer window frame with a pair of jambs and a sill, and a glass unit carried by the window frame. A pair of brackets are attached to the jambs proximate corners between the jambs and the sill. Each bracket has an upright member, a horizontal member orthogonal to the upright member and a hook attached to a rear surface of the upright member. The brackets attach to the jambs so that the hook extends through a hole in the jamb, the upright member is adjacent a surface of the jamb and the horizontal member is disposed above (e.g., spaced above) the sill. The brackets support and transfer the weight of the glass unit to the jambs to inhibit (e.g., prevent) the sill from bearing the load of the glass unit, thereby inhibiting (e.g., preventing) the crushing or bowing of the sill by the glass unit and thereby inhibiting (e.g., preventing) the formation of gaps in the window assembly that allow for air and/or water infiltration through the window assembly.

A corner key includes a heel and at least one leg extending from the heel defining a longitudinal axis. A nose is disposed along the longitudinal axis. The nose includes a first wedge area and an opposite second wedge area. The corner key further includes a bridge connecting the nose to the at least one leg. Upon insertion into a frame member, the nose substantially rotates to engage both the first wedge area and the second wedge area within the frame member and wedge the nose therein.
