A connection utilizing a joist hanger to hang a joist or beam from a wood structural support member such as a top plate or header in cooperation with a first plurality of fasteners such as screws and one or more substantially vertical fire-resistant panels such as drywall.

A fastening system for joining two structural members is provided. The fastening system includes a latching device comprising a housing, at least one eccentric rotatable part and a generally S shaped latch spring hook joined to the rotatable part, and a receiver having at least one hole configured to receive a free end of the latch spring hook. In one embodiment, the bottom portion of the housing is generally semi-circular in shape and the receiver includes two semi-circular frames having a corresponding radius to receive the lower portion of the housing. The latching device is fixed to a first structural member and the receiver is fixed to a second structural member. The structural members may be joined by positioning an end of the first structural member adjacent to the receiver of the second structural member and rotating the rotatable part to cause the free end of the latch spring hook to engage the hole in the receiver. Further rotation of the eccentric rotatable part causes the latch spring hook to exert a pulling force, thereby joining the structural members together. The semi-circular lower portion of the housing and the semi-circular frames on the receiver allows the structural members to be attached at any desired angle using one fastening system.

A fastening system for joining a first structural member end-on to a second structural member is provided. The fastening system includes a latching device comprising at least one eccentric rotatable part and at least one generally S shaped latch spring hook joined to the rotatable part, and a receiver having at least one hole configured to receive a free end of the latch spring hook. The latching device is fixed to an end of a first structural member and the receiver is fixed to a side of a second structural member. The first structural member may be joined end-on to the second structural member by positioning the latching device on the first structural member adjacent to the receiver of the second structural member and rotating the rotatable part to cause the free end of the latch spring hook to engage the hole in the receiver. Further rotation of the eccentric rotatable part causes the latch spring hook to exert a pulling force, thereby joining the structural members together.

To provide a building frame for constructing a building, the frame being stronger than reinforced concrete, and being able to be relatively easily assembled at a construction site, without skills, and within a short time. Provided are a building frame and the like, the building frame being characterized by comprising: U-shaped parts that are arranged left and right so as to sandwich a center space in a cross-sectional view; and a connection part that connects top portions, on the center side, of the left and right U-shaped parts so as to form a reverse U-shaped part, wherein the longitudinal edges, on the far side from the center, of the U-shaped parts arranged left and right in the cross-sectional view are shorter than the longitudinal edges, on the center side, connected by the connection part.

An end bracket for a wall system includes a body member having attachment structure to join a horizontal strut to a vertical strut. The end bracket further includes attachment structure in which the horizontal strut is slidably attached for moving and positioning the horizontal strut relative to the vertical strut in forming the wall system.

Floor panels which are provided with a mechanical locking system including an extruded flexible tongue in a sidewardly open groove which during a vertical folding motion is bent horizontally. A tongue adapted for being received in a sidewardly open groove of a floor panel, wherein the tongue, which is an elongated extruded section, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel, such that the tongue is at least partially resiliently displaceable inside said sidewardly open groove in said plane during locking of the floor panel with another floor panel and wherein a vertical protrusion, serving as a friction connection between the tongue and the groove, is arranged at an upper or lower part of the tongue, wherein the tongue has a length in the longitudinal direction of the tongue and a total width perpendicular to the length, and the total width varies in the longitudinal direction of the tongue.

One embodiment provides a pre fabricated kit for assembling a supporting framework comprising a plurality of customized beams or supports with a connection openings/hole patterns selected from a set of connection hole patterns and using a plurality of generic connectors which fit on the interior of the customized beams or supports.

A removable fastener for securing a first stud to a second stud each stud having an aperture with lateral and bottom edges, includes a joining member with a first end and second end having first and second notches sized to admit lateral edges made adjacent by placing the studs back-to-back. Fastener includes a locking member that has a stud end configured to rest on the bottom edges of the apertures and a fastener end configured to attach to the joining member, holding the joining member in position within the apertures when the joining member is engaged within the apertures; the fastener end may include a clip.

A bridging termination clip for securing the terminal end of a steel channel or spazzer bar to a steel stud. The bridging termination clip may include a horizontal portion having a bridge plate and a pair of opposing legs, the legs extending vertically one from each side edge of the bridge plate in a substantially perpendicular relation thereto; a vertical plate connected to a rear portion of the bridge plate and extending upward in a substantially perpendicular relation thereto; and an opposing pair of side extensions connected to the vertical plate and extending rearward one from each side of the vertical plate in a substantially perpendicular relation thereto.

Supplemental support structure for a hot aisle/cold aisle forming apparatus having vertical supports and a grid of parallel and perpendicular rows of elongated grid members attached to and supported by the vertical supports is disclosed. The supplemental support structure may include vertical support caps attached to the hot aisle/cold aisle forming apparatus above the vertical supports and the grid of parallel and perpendicular rows of elongated grid members and a grid of elongated cross supports. Each of the elongated cross supports may be connected to and supported by at least two of the vertical support caps at an angle of other than 0, 90, 180, and 270 with the parallel and perpendicular rows of elongated grid members.
