The invention relates to a fastening system (1) for rectangular, tabular panels (2, 3, 10), especially floor panels. Comprising retaining profiles disposed on the small faces of said panels (2, 3, 10). Opposite retaining profiles match said retaining profiles in such a manner that similar panels (2, 3, 10) can be interlinked. The panels are provided with opposite first retaining profiles that are configured in such a manner that on a panel (2, 3, 10) being in first line a new panel (2) can be locked in second line by attaching the new panel (2) to the installed panel (3) at a temporary angle relative to the installed panel (3) and then swiveling it down into the plane of the installed panel (3). The panel further comprises opposite second retaining elements that comprise corresponding hook elements (6, 7). A hook connection (8) can be established by means of one of the hook elements (6, 7) of the new panel (2) and a hook element (6, 7) of a panel (3) that is already installed in second line by swiveling down the new panel (2). Every hook connection (8) is associated with an additional locking element (13, 22, 26, 27, 34, 35, 36, 40, 46) that prevents, in the hooked state of two panels (2, 3, 10), the hook connection (8) from being released in a direction perpendicular to the plane of the installed panels (2, 3 10).

The two-piece extrusion permits wall panels to be mounted or removed from the underlying wall structure in on-sequential order. The receiver base and cap can be provided on both sides to form an "H" type extrusion, or on only one side in a "J" type extrusion. Preferably, the outer cap is made of metal, and the tips of the insertion fingers are beveled at a slight angle of about 7° to 14° to allow easy insertion into the receiver flanges. The cap has compound water-shedding edges formed with a rounded rain-drip edge spaced in close proximity to a sharply inclined knife edge.

The base portion is formed with a hook indentation on a back side of the ramp on a rear surface of the base portion, and interconnects with a "Z" type extrusion having a hook end to form a right angle connection. The one-piece extrusion may be formed as a "J" (one-sided), "H" (two sided), "C" (corner), or other suitable types.

The self-heat-preservation wall body consists of the self-heat-preservation building blocks. The self-heat-preservation building block and the self-heat-preservation wall body have functions of heat preservation and fire prevention as well as bearing.

In the invention, the same clad bricks are laid in the forward direction, and a positioning convex platform 2 and a longitudinal positioning convex platform 3 are used for realizing transverse and longitudinal self-locking positioning, thereby naturally ensuring the designed thickness and surface smoothness of the wall, forming a combined still air layer 12 which is 9mm to 10mm wide and vertical to the ground, and further blocking heat bridges in vertical bricklaying seams. The cavity of a 28-30mm-wide groove 4 in the horizontal bricklaying seam between two clad bricks is filled with a broken bridge insulation board 10 which is as wide as the groove and has a thickness of 15mm; the broken bridge insulation board 10 is used for sealing a long-strip groove still air layer 11 and the combined still air layer 12 and cutting off the heat bridges in the horizontal bricklaying seams; the exposed part of broken bridge insulation board with a height of 10mm, is used for controlling the coating thickness of anti-crack masonry mortar 13 to be even and uniform. When the self-insulating and energy-saving wall is built, Z-shaped energy-saving building blocks 1 of the upper clad bricks and the lower bricks are laid in a staggered manner so as to cut off heat bridges in vertical bricklaying seams. The structure of the invention, with a reasonable thickness, can satisfy the requirement of saving 50 percent of energy in various regions, or even higher requiremets without an internal or external insulating layer of walls. Simultaneously, the structure is easy to build and the formation of the block shape effectively ensures the thickness of walls and the smoothness of wall surfaces. The thermal insulation function of the still air layer with a thickness of 10mm to 12mm strengthens the heat insulation effect. The insulation boards (28-30mm wide and 15mm thick) between the two clad bricks is capable of cutting off the heat bridge effects.
