A structural post includes a base plate defining a plurality of through holes, and a post portion that includes at least a pair of internal walls and at least a pair of external walls. A connector block is configured to receive a locking screw and to engage with a bolt thread of a bolt. A lock plate has a plate thread that is configured to engage the screw thread of the locking screw, and the lock plate is configured to expand upon being drawn by the locking screw into tight engagement with the connector block. The expanded lock plate is configured to apply a force on one of the pair of internal walls and one of the pair of external walls.

Sunshading louver control system and method based on gesture recognition are provided. Indoor images are collected in real time. Based on the indoor images, an action region of gesture motion is positioned and feature extraction is performed thereon to obtain hand motion parameters. The hand motion parameters are analyzed to obtain gesture information. The gesture information is compared with preset gesture information. When the preset gesture information contains the gesture information, corresponding adjustment is performed on a sunshading louver according to a preset operation logic corresponding to the gesture information. When the preset gesture information does not contain the gesture information, the gesture information is determined to be invalid. The lifting and rotation angles of the louver can be automatically controlled according to various gestures of indoor personnel, thereby rapidly realizing regulation of indoor illumination and natural ventilation quantity, and meeting the change of personnel's demand for indoor environment.

An adjustable support for a panel is provided to allow control of the height and the tilt angle of the panel. The support includes a hollow cylindrical base having an outer diameter D.sub.1; a first hollow piston having an outer diameter D.sub.2 threadably engaged with the base; a second hollow piston having an outer diameter D.sub.3 threadably engaged with the first piston; a third piston having an outer diameter D.sub.4 threadably engaged with the second piston, such that D.sub.1>D.sub.2>D.sub.3>D.sub.4. A ball pod extends from the third piston and accommodates a ball attached to the panel. One or more stepper motors are provided, where each stepper motor is coupled to a bottom portion of a respective piston, and a rotor of each stepper motor is configured to rotate the corresponding piston, thereby causing the piston to move along a longitudinal axis of the support.

Disclosed is a terrace canopy comprising a beam which is constructed from a set of profiles. The set includes a beam profile provided to serve as a beam of the terrace canopy, in which the beam profile has an upright inner side wall and a first connection means. The set also comprises two mutually different spacer profiles, each of which is attachable to the beam profile via the first connection means. Each spacer profile also has a further connection means to which a beam-finishing profile can be attached, which beam-finishing profiles also form part of the set. The spacer profile determines the distance between the outward facing surface of the beam-finishing profile and the upright wall of the beam profile. Hence, the width of the beam can be varied depending on the type of wall infill.

Disclosed is a terrace canopy, comprising a beam having a top side, a bottom side, an inner side and an outer side, and, in its cross-section, is provided with a screen cavity which is delimited by an upright inner side wall and a horizontal top wall and an internal space above the screen cavity. An upright wall extends from the end of the horizontal top wall. The beam comprises either a first closure profile for closing off the internal space or a wall profile attached to the upright wall and a second closure profile for closing off the internal space. Thus, multiple configurations of the beam are possible and an additional wall holder may be provided on the outer side of the screen cavity such that a double side wall infill is possible.

Disclosed is a terrace canopy, comprising a beam which a top side, a bottom side, an inner side and an outer side, and, in its cross-section, is provided with: a screen cavity and a U-shaped space at the bottom side of the beam which is located below the screen cavity and open at its bottom side. The U-shaped space is configured to hold a first profile and a second profile, different from the first profile, and is provided with: a first and a second connection means configured together to hold the first profile or the first connection means and a connection wall portion configured together to hold the second profile. By leaving the U-shaped space open at its bottom side and providing the connection means, it is possible to integrate other profiles into the beam.
