Provided is a construction panel assembly, which is applicable to a detachable method capable of assembling and disassembling a ceiling, a wall or a floor material which partitions spaces of various kinds of buildings. Also, the construction panel assembly allows materials to be reused, so that the generation of construction waste may be minimized.

A modular panel system including a plurality of posts where each post includes a front face, a rear face, and opposed lateral faces. A central channel is formed in the front face where the central channel has a linking opening, a first ledge and a second ledge. Cutouts are formed in the ledges. The rear face includes a panel receiving channel that receives an edge of a panel. A linking element is configured to be secured in the linking opening. The head of the linking element is sized to fit within the first and the second cutouts and be secured by the first and second ledges to couple the first post to the second post. The lateral faces of the coupled posts together form a first side central channel and a first side central channel cutout that is configured to receive a second linking element to couple a third post to the coupled first and second posts.

A locking post for a closure, the post having front and rear walls joined at their sides by two side walls to form a tubular post having a generally quadratic cross-sectional shape. Each side wall has a groove therein, the groove parallel to the longitudinal axis of the post, and wide enough and deep enough to at least partly receive a locking element carried by the post. The sides of the groove also provide handles which can be gripped to move a closure the post is mounted on.

An assembly of extruded members including: an extruded housing member including one or more holes formed along at least one side thereof for entry of ends of one or more second extrusions therethrough; and at least one extruded aluminum clamping member including one or more pairs of opposed clamping portions for clamping the ends of the one or more second extrusions therebetween.

A fixing device for mounting wall elements for constructing a wall, includes: a support profile, A securing element which is designed to extend between the wall elements and can be twisted relative to the support profile between a first position in which an engagement element of the securing element remains separate from the support profile, and a second position in which the engagement element engages on the support profile for fixing and secures the wall elements; and a closing profile which in the second position is attachable to the securing element and comprises a blocking element for preventing the securing element from twisting back.
