A decorative moulding assembly for a wall or ceiling in an interior space. The decorative moulding assembly may include a first moulding piece and a second moulding piece each having an ornamental front surface, a rear surface, and a channel in the rear surface and a connector for connecting the first and second moulding pieces together. The connector may include a first portion that nests within the channel of the first moulding piece and a second portion that nests within the channel of the second moulding piece. The first portion of the connector may include a U-shaped body having first and second legs that deflect inwardly towards one another as the first portion of the connector is being inserted into the first channel of the first moulding piece.

A fractal structure system provides building components with different sizes, which a building component with the next smaller size can insert into or attach to a building component with the next larger size. Each building component has a plurality of channel walls radiating outwardly, and the plurality of channel walls forms a plurality of channels. Each building component further comprises an internal center bore, and the internal center bore includes a plurality of internal center bore corners aligning to said plurality of second channel walls. Different sizes of building components have the same cross sectional profile, which a fractal structure or pattern can be implemented with the different sizes of building components.

An assembled structure system includes a prefabricated member, a fastener and a locking member. The prefabricated member is provided with at least one cavity, and the fastener is assembled in the at least one cavity. At least one fastener is assembled in each cavity. The cavity includes an upper end surface, a lower end surface, a left end surface and a right end surface. The left end surface or the right end surface includes a vertical surface perpendicularly connected to the upper end surface and an inclined surface connected to the vertical surface. A connection angle between the vertical surface and the outer side of the inclined surface forms an obtuse angle. The inclined surface is connected to the lower end surface. The fastener includes a fixed surface, two side surfaces and a bottom surface. The fixed surface, the two side surfaces and the bottom surface are hingedly connected.

To provide a post-installed anchor capable of being used repeatedly and being easily removed and recovered.

A post-installed anchor to be inserted and fixed in an anchor insertion hole formed in a structure includes: a cylindrical anchor body; expandable pieces obtained by dividing the tip side of the anchor body into a plurality of pieces by a plurality of slits 16 which are formed on the tip side, leaving equal intervals in a circumferential direction and extending in the axial direction of the anchor body, the expandable pieces each having a plate-like part whose surface is formed into a flat surface and which has spring force, a fixing part formed at the tip of the expandable piece and having a larger thickness than that of the plate-like part, and an inclined part whose inner surface is gradually inclined inward toward the tip of the expandable piece; a female screw formed in an inner surface of an unexpandable part side of the anchor body; and a male screw body formed into a substantially columnar shape that can be inserted into the anchor body, having a wedge part with a truncated conical shape at its tip, having a male screw screwed with a female screw formed in the anchor body at its rear end side, and having a rotary tool engagement part at its rear end surface. The male screw body is advanced with the male screw of the male screw body screwed with the female screw of the anchor body to make the truncated conical shaped wedge part at the tip of the male screw body abut against the inclined part formed so that the inner surface thereof is gradually inclined inward toward the tip side of the expandable piece to expand the expandable piece by wedge action, pressing the outer surface of the fixing part against the hole wall of the anchor insertion hole, which thereby fixes the post-installed anchor in the anchor insertion hole, and the male screw body is retracted to close the expanded expandable piece by spring force of the plate-like part of the expandable piece for recovery and reuse.

A locking assembly (100) for securing one or more building elements in a building system is disclosed herein. The locking assembly (100) comprises: a first component (110) adapted for engagement to the building system, the first component (110) including a first locking portion (112) defining a first surface profile; a second component (120) including a second locking portion (122) defining a second surface profile corresponding to the first surface profile of the first locking portion (112), the second locking portion (122) being adapted for engagement with the first locking portion (112); and a third component (130) having a first end and a second end, the first end being adapted for engagement with the second locking portion (122) of the second component (120), wherein the third component (130) is resiliently deformable from a locked configuration to an unlocked configuration under application of force to the third component (130), wherein in the locked configuration, the second locking portion (122) is engaged to the first locking portion (112) so as to secure the first component (110) to the second component (120), and in the unlocked configuration, the second locking portion (122) is disengaged from the first locking portion (112).

A modular workspace system employs a plurality of interchangeable posts, beams/rails, and panels, permitting assembly of modular rooms and modular room structures of varying size, shape, and purpose. Wire management openings permit internal wire management.

A locating pin assembly for coupling a first modular frame to a second modular frame is disclosed. The locating pin assembly has a first gusset plate positioned between the first modular frame and the second modular frame. The first gusset plate has a first gusset plate aperture and a second gusset plate aperture for receiving fastening means for coupling the first-modular-frame-first-beam and the second-modular-frame-first-beam the gusset plate. The pin assembly also has a pin engaging the first gusset plate, the first modular frame and the second modular frame. Also disclosed are modular frame units having the pin assembly, system of modular frame units having the pin assembly and a method of coupling modular frame units.
