In order to improve the heat preservation and heat insulation performance of a wall body, after a light batten is installed, the insulation board still needs to be adhered and anchored on site, but the material strength is low due to the low volume weight of the light batten, so that the mechanical property of the insulation board for anchoring is poor, the anti-drawing force of an anchor bolt is only 0.3-0.4 kN according to the current national standard, and the problem that the insulation board falls off is often caused. In order to solve the problem, the chinese patent application No. 202111076181.2 discloses a composite heat-insulating slat, which is composed of an aerated concrete layer, a heat-insulating board, a steel wire mesh and plastic anchors, but the composite heat-insulating slat is still manufactured by post-pouring aerated concrete, which is not beneficial to dry operation.
