Description

Rural residential plant material thermal insulation composite wall and method for preventing moths

technical field

The invention relates to a composite wall body and an insect-proof method thereof.

Background technique

The rural areas in northern my country are rich in plant resources, such as wild reeds, wormwood, and plant stalks discarded after agricultural production. These plant materials can be used as building insulation materials. The cost of plant insulation materials is low, and the production process is simple. There are already certain building scales in some areas in northern my country. Existing research data show that composite walls with plant material insulation layers can effectively improve the thermal insulation performance of rural residential exterior walls, so this type of composite walls has great potential for development.

Due to cooking and other reasons, the indoor air humidity will exceed the standard. According to relevant data, the air humidity in the wall of the plant material building can reach 70% to 80% in a certain period of time. In this case, the humid air passes through the brick wall. , into the plant material insulation layer, the plant material insulation layer will be mildewed and rotted, thereby reducing the thermal insulation performance, which will seriously affect the structural safety and durability of the plant material building wall. In addition, in rural areas, the plant material The insulation layer also faces the problem of moths and rats. Due to the natural environment in the countryside, the wall materials are eaten by moths and rats. For walls with this sandwich insulation structure, once the insulation layer in the wall is damaged, it cannot be repaired in time. Repairing or replacing, trimming needs to destroy the interior wall, and tear down the brick wall on one side of the interior, which will directly affect the use of the residents, and also destroy the stability of the wall.

Contents of the invention

The invention aims to solve the problems that the existing rural residential plant material thermal insulation composite wall is damp and insect-eaten, which leads to poor thermal insulation performance of the wall and reduces the structural safety and durability of the wall, and further provides a rural residential plant material thermal insulation composite wall. Walls and their methods of preventing moths.

The technical scheme that the present invention takes for solving the problems of the technologies described above is:

The plant material thermal insulation composite wall of the rural residence and the insect-proof method thereof of the present invention comprise an outdoor brick wall layer, a plant material thermal insulation layer, a plastic moisture-proof layer and an indoor brick wall layer, an outdoor brick wall layer, a plant material thermal insulation layer, a plastic moisture-proof layer and The indoor brick wall layer is arranged in parallel from the outdoor to the indoor. The plant material insulation layer is a plant plate formed by extrusion of plant material. There is an air layer between the outdoor brick wall layer and the plant material insulation layer. The outdoor brick wall layer is along the thickness direction. There are a plurality of ventilation through holes, and a ventilation pipe is arranged in each ventilation through hole. Both ends of the ventilation pipe are provided with metal mesh, and the end outside the ventilation pipe is lower than the other end of the ventilation pipe.

The anti-moth-eaten method of the plant material thermal insulation composite wall of the rural house of the present invention is realized according to the following steps: the plant material thermal insulation layer is to add quicklime evenly to the extruded plant material before the extruded plant material, and the quicklime accounts for 1% of the plant material The range of volume percentage is 2-10%.

The beneficial effects of the present invention are:

An air layer is arranged between the outdoor brick wall layer and the plant material insulation layer of the rural residential plant material thermal insulation composite wall of the present invention, and an air layer is arranged on the outdoor brick wall layer. The air layer communicates with the outside through the air tube. Once the plant material is damp Moisture can be discharged to the outside in time through the air layer and the ventilation pipe, and metal mesh covers are installed at both ends of the ventilation pipe to prevent insects from climbing into the wall;

The plant material thermal insulation composite wall of the rural residence of the present invention is provided with a plastic moisture-proof layer on the side of the plant material thermal insulation layer close to the room, which avoids the side of the plant material thermal insulation layer from getting damp, and is different from the existing plant material thermal insulation wall. Ratio, to avoid the plant material insulation layer from getting wet;

The method for preventing moth-eaten by plant material thermal insulation composite walls of the rural dwellings uniformly adds quicklime to the plant material, so that the plant material thermal insulation layer is prevented from moth-eaten and rat-knocked, and the plant material thermal insulation layer does not need to be repaired after the building is completed.
