specific Embodiment approach 1

[0013] Specific implementation one: as figure 1 As shown, the rural residential plant material thermal insulation composite wall in this embodiment includes an outdoor brick wall layer 1, a plant material thermal insulation layer 2, a plastic moisture-proof layer 3 and an indoor brick wall layer 4, an outdoor brick wall layer 1, and a plant material thermal insulation layer 2. , The plastic moisture-proof layer 3 and the indoor brick wall layer 4 are arranged in parallel from the outdoor to the indoor. The plant material insulation layer is a plant material formed by extrusion of the plant material, and between the outdoor brick wall layer 1 and the plant material insulation layer 2 is an air layer. 5. A plurality of ventilation through holes 1-1 are opened on the outdoor brick wall layer 1 along the thickness direction, each ventilation through hole 1-1 is provided with a ventilation pipe 1-2, and both ends of the ventilation pipe 1-2 are set There is a metal mesh 1-3, one en...

specific Embodiment approach 2

[0015] Specific implementation two: as figure 1 As shown, the included angle formed between the ventilation tube 1-2 and the horizontal direction in this embodiment is 3-20°. This design can prevent rainwater from flowing into the air layer 5 . Other components and connection relationships are the same as in the first embodiment.

specific Embodiment approach 3

[0016] Specific implementation three: as figure 1 As shown, the thickness of the plant material heat insulating layer 2 in this embodiment is 210 to 280 mm. This design has good thermal insulation effect. Other compositions and connection relationships are the same as in the first or second embodiment.

Abstract

The invention discloses a rural resident plant material thermal-insulating composite wall body and an anti-worm-damage method thereof, which relate to a composite wall body and an anti-worm-damage method thereof and are used for solving the problems of poor thermal-insulating effect on the wall body and reduction in the structural safety and durability of the wall body caused by damping and worm damage of the conventional rural resident plant material thermal-insulating composite wall body. A plant material thermal-insulating layer is a plant plate formed by extruding a plant material; an air layer is formed between an outdoor brick wall layer and the plant material thermal-insulating layer; the outdoor brick wall layer is provided with a plurality of ventilation through holes along a thickness direction; a ventilation pipe is arranged in each ventilation through hole; the two ends of the ventilation pipes are provided with metal nets; one outdoor end of each ventilation pipe is lower than the other end of the ventilation pipe; in the plant material thermal-insulating layer, quicklime is uniformly added into a forwardly-extruded plant material; and the quicklime accounts for 2-10 percent by volume of the plant material. The rural resident plant material thermal-insulating composite wall body is applied to damp prevention and worm damage prevention of composite wall bodies.

Description

technical field [0001] The invention relates to a composite wall and a method for preventing moths. Background technique [0002] The rural areas of northern my country are rich in plant resources, such as wild reeds, wormwood and plant straws discarded after agricultural production. These plant materials can be used as thermal insulation materials for buildings. Plant thermal insulation materials are low in cost and simple in production process. There are already certain construction scales in some areas of northern my country. The existing research data shows that the composite wall of plant material thermal insulation layer can effectively improve the thermal insulation performance of the outer wall of rural residential buildings, so this kind of composite wall has great potential for development. [0003] Due to cooking and other reasons, the indoor air humidity may exceed the standard. According to relevant data, the air humidity in the plant material building wall can...
