Composite insulation outer wall prefabricated board and use method thereof

Abstract

The invention discloses a composite insulation outer wall prefabricated board. The composite insulation outer wall prefabricated board comprises a board body which consists of a foamed ceramic surface layer, foamed ceramic inner partition boards and insulation filling bodies, wherein the foamed ceramic surface layer forms a closed cavity, the cavity is separated into multiple independent unit cavities by the foamed ceramic inner partition boards, and the unit cavities are filled with the insulation filling bodies. The composite insulation outer wall prefabricated board has the characteristics of thin wall body, lightness and good composite insulation efficiency. A use method of the composite insulation outer wall prefabricated board comprises the following steps: (a) board selection, (b) board building, and (c) perfusion. The composite insulation outer wall prefabricated board built according to the use method has the characteristics of steady structure and versatility.

Description

technical field [0001] The invention relates to a prefabricated panel for exterior walls, more specifically, to a prefabricated panel for thermal insulation composite exterior walls; the invention also relates to a method for using the prefabricated panel for exterior walls. Background technique [0002] According to the requirements of the "Medium and Long-term Special Plan for Energy Conservation" promulgated by the state, by 2020, new buildings must achieve at least 65% energy-saving goals, and a good external wall insulation system is the key to building energy conservation. Building industrialization is to manufacture houses in a large-scale industrial production method to improve production efficiency and overall quality, and effectively reduce building energy consumption, resource energy and environmental impact, so that it meets the relevant policy requirements of the national housing industrialization. At present, the existing energy-saving and thermal insulation ex...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing thermal insulation exterior wall needs to be completed in two constructions. First, the exterior wall is built, and then the insulation board is installed on the exterior wall. The masonry process is complicated and the construction period is long, which cannot meet the needs of building industrialization. needs

[0004] 2. The effect of the existing prefabricated slab walls is poor, mainly due to the high thermal conductivity of concrete materials and the low composite efficiency of high-efficiency thermal insulation materials, so the thermal bridges such as the concrete ribs and metal connectors around the prefabricated slab and the opening are affected. The impact is very obvious. This part has caused the thermal insulation efficiency of the prefabricated panel wall to drop, which may reach 50% to 80%.
