A multidirectional aluminum extrusion connection device includes a direction-change coupling member having two ends respectively forming first and second coupling sections arranged in an angularly-staggered manner to extend in different directions for each connectable with a connection member. A first aluminum extrusion plate is provided to receive one of the connection members to extend therethrough so as to be set at a location corresponding to the first coupling section. A second aluminum extrusion plate is provided to receive the other one of the connection members to extend therethrough so as to be set at a location corresponding to the second coupling section. The first and second aluminum extrusion plates are thus connected in an angularly staggered manner to form a connection module having and defining a corner. The connection members may be additionally connected two pre-prepared aluminum extrusion parts for respectively coupling to the first and second aluminum extrusion plats.

A framing system includes a corner bracket having a first planar portion and a second planar portion. The first planar portion and the second planar portion are configured to at least partially receive a corner post therebetween. The corner bracket also includes a first attachment portion and a second attachment portion. The first attachment portion is attachable to a first joist of a deck. The second attachment portion is attachable to a second joist of the deck. The framing system also includes a corner profile attachable to the corner bracket and the corner post. The framing system further includes at least one horizontal profile attachable to the corner profile. The framing system also includes at least one panel attachable to the corner profile.

An extruded profile defining a normal section surface, a horizontal loading direction along the normal section surface and a vertical loading direction along the normal section surface perpendicular to the horizontal loading direction The profile includes a core arranged in a central position at the intersection of the directions, a plurality of arms each including a radial segment radially connected to the core and a tangential segment perpendicularly connected to the radial segment The radial segments of the adjacent arms are perpendicular to each other and each oriented 45? to the horizontal load direction and/or the vertical load direction, and the tangential segments of the adjacent arms are configured to simultaneously support the same load along the horizontal load direction and/or the vertical load direction.

A framing system for constructing at least a portion of a building. The framing system comprising beams, cross beams, corner posts, and inline posts. The beams including flanges and a wall arranged between the flanges. The cross beams including a flange and a wall attached to the flange. The corner posts including walls and flanges. The inline posts including flanges and a wall arranged between the flanges. The flanges include slots and the walls include open areas. Panels may attach to the slots. Decorative patterns may be integrally formed in the open areas.

A quick attachment system is disclosed. A first connector portion is defined along a surface of the first member and a second connector portion is defined along a surface of the second member. The first connector portion comprises a protrusion of the surface of the first member. The second connector portion comprises a detent of the surface of the second member. The first and second connector portions may mate with and engage one another to secure the first member against the second member. A modular frame unit comprises first and second channel members defining first connector portions along lengths thereof and a joinder channel member defining second connector portions along a length thereof. Each of the second connector portions is configured to mate with one of the first connector portions to join the joinder channel member with the first and second channel members.

To enhance the positioning accuracy between primary members and auxiliary members without need of latch parts such as rivets, an insertion frame structure includes: a pair of primary members having L-shaped cross-sections and placed with the L shapes facing to each other symmetrically; and several auxiliary members having angular U-shaped cross-sections between the primary members. The primary members and the auxiliary members are joined at latch portions. The latch portions of the primary members have clearance-shaped latch holes. The latch portions of the auxiliary members have convex portions to be inserted into the latch holes. Each latch hole has a clearance with a larger dimension than a plate thickness t of the auxiliary members, and continuously from the clearance, a clearance with a dimension smaller than the plate thickness t of the auxiliary members.

Modular structure including profile defining a prevailing development axis, and having a perimeter wall including a groove both extending parallel to the prevailing development axis, at least two edges delimiting the groove, wherein at least part of one is indented; connection for constraining more than one profile and including at least one connector including a flat body extending along a principal axis, including a first constraint guide to couple with a first constraint device and defining side walls and at least partially indented to block mutual translation between connector and profile along the main axis when the connector is in the groove, an obstruction element detachably constrainable to the body for interacting with the profile to block the connector with respect to the profile. The body includes a second constraint guide for housing at least part of a second constraint device to constrain the obstruction element and the connector.
