Problems solved by technology

[0002] The external wall panels in the existing prefabricated buildings are mainly concrete wall panels, which do not have thermal insulation performance. After the external wall panels are fixed on the beams or walls, another insulation layer needs to be made on the construction site of the building, and the construction is complicated. , the insulation layer is easy to hollow, crack, and fall off, leaving potential safety hazards
[0003] At present, the main problem of self-insulating external wall panels is that the thermal insulation performance is difficult to meet the requirement of 65% building energy saving. Extruded plastic board is used as the thermal insulation layer. The extruded plastic board is incompatible with cement, and the connecting steel bars will generate heat and cold when passing through the thermal insulation layer. bridge, causing problems such as condensation

Abstract

The invention discloses a making method of a self-thermal insulation external wall panel for a fabricated building. The method comprises the following steps: (1) making a first surface reinforcing layer: laying cement slurry or crack-resistant mortar on a steel mesh or a piece of fiber gridding cloth as the first surface reinforcing layer; (2) making a thermal insulation layer: pouring thermal insulation slurry onto the first surface reinforcing layer to form a thermal insulation board; (3) making a second surface reinforcing layer: laying a steel mesh or a piece of fiber gridding cloth as well as cement slurry or crack-resistant mortar on the thermal insulation board as the second surface reinforcing layer; (4) arranging an anchored external steel bar: enabling one end of the connecting steel bar to pass through the second surface reinforcing layer and the thermal insulation plate and anchoring in the first surface reinforcing layer, and enabling the other end of the connecting steelbar to be positioned outside a self-thermal insulation wall panel so as to form the self-thermal insulation external wall panel, wherein a hot bridge of the connecting steel bar is provided with an insulation layer. The making method provided by the invention improves the thermal insulation property of the external wall panel, and eliminates cold and hot bridges of the external wall panel. When being popularized, the making method has greater economic benefit and social benefit.
