[0002] Autoclaved lightweight concrete board (ALC) is a kind of high-performance autoclaved aerated concrete, which is made of fly ash (or silica sand), cement, lime and other raw materials, cured by high-pressure steam, and built with treated steel bars for reinforcement. It can be used as both wall material and roofing board, and has the characteristics of heat preservation, sound insulation, anti-seepage, environmental protection, and easy construction. It is a new type of building material with superior performance.

[0003] As a new type of wall material, autoclaved lightweight concrete (ALC) panels have various reinforcement connection methods. The most commonly used method is U-shaped card and mortar filling. This method is particularly suitable for situations where there are no openings in the wall. However, for the parts of the wall door and window openings where horizontal and vertical ALC boards are combined, the U-shaped card and mortar filling connection method is not applicable.

[0008] The upper limit plate comprises two groups of straight plates arranged vertically upward, and the heights of the two straight plates are the same.

[0009] The distance between the two straight plates of the upper limit plate is greater than the distance between the two separating grooves.

[0010] The upper limit plate comprises two groups of straight plates arranged vertically downward, and the two straight plates have the same height.

[0011] The distance between the two straight plates of the lower limit plate is greater than the distance between the two separating grooves.
