Embodiment 1

[0024] Embodiment 1: see figure 1 , the method for enhancing the thermal insulation performance of the well dry wall with light raw earth materials is to wet the inner surface of the wooden flute of the well dry building wall with water, and then use raw soil, cement and plant fiber to add water and mix the lightweight Using high-quality clay slurry, fill the gaps on the inner surface of the wooden flute of the well dry wall, and then use cement mortar to build lightweight clay blocks prefabricated with light clay slurry on the outer surface of the filling layer to form 30mm thick wall insulation. On the exterior of the wall insulation layer, a 3mm thick surface layer is formed by plastering with a mixture of raw soil and cement as a surface decoration.

[0025] The lightweight clay slurry used in this method is obtained by mixing dry-based raw soil, cement and wheat straw with a length of 10mm in a mass ratio of 6:2:2, and then adding water in a mass percentage of 30% and m...

Embodiment 2

[0027] Example 2: see figure 1 , The method for enhancing the thermal insulation performance of the well dry wall with the light raw earth material and the obtained well dry wall thermal insulation wall structure are the same as in Example 1. The difference is: the lightweight clay slurry is obtained by mixing dry base soil, cement and 30mm long bamboo filaments in a mass ratio of 5:3:3, and then adding water at a mass percentage of 30% to mix evenly. The slurry; the raw soil and cement mixed slurry used in the plastering surface layer is obtained by mixing the dry base raw soil and cement at a mass ratio of 5:1, and then adding water to mix uniformly at a mass percentage of 30%. slurry. In the lightweight clay leveling layer 2 and the lightweight clay block insulation layer 3, the mass ratio of dry base raw soil, cement and plant fiber is 5:3:3; in the plastering surface layer 4, the mass ratio of raw soil to cement The ratio is 5:1; the wall insulation layer 3 is 150mm th...

Embodiment 3

[0028] Embodiment 3: see figure 1 , The method for enhancing the thermal insulation performance of the well dry wall with the light raw earth material and the obtained well dry wall thermal insulation wall structure are the same as in Example 1. The difference is: the lightweight clay slurry is obtained by mixing dry base soil, cement and weed straw with a length of 40mm in a mass ratio of 5:4:2.5, and then adding water at a mass percentage of 32% to mix evenly. The raw soil and cement mixed slurry used in the plastering surface layer is obtained by mixing dry-based raw soil and cement at a mass ratio of 4:1, and then adding water at a mass percentage of 25% to mix evenly slurry. In the lightweight clay leveling layer 2 and the lightweight clay block insulation layer 3, the mass ratio of dry soil, cement and plant fiber is 5:4:2.5; in the plastering surface layer 4, the mass ratio of raw soil to cement The ratio is 4:1; the wall insulation layer 3 is 100mm thick, and the pl...

Abstract

The invention provides a method for enhancing the thermal-insulation performance of a well-frame wall body by adopting a light raw soil material and a composite thermal-insulation wall body, and belongs to the technical field of buildings. The method comprises the following steps: light clay slurry formed by mixing raw soil, cement and plant fiber is used for filling slits on the well-frame wall body, so as to form a flatting layer; pre-cast light clay building blocks are built on the surface of the flatting layer; and slurry formed by mixing raw soil and cement or a surface finishing material such as board is adopted as a surface layer. The composite thermal-insulation wall body mainly comprises a beam, a wood ridge, a light clay flatting layer filled in the slits on the surface of the wood ridge, and a light clay building block thermal-insulation layer built on the surface of the flatting layer. The invention has the advantages that the materials are mainly local construction materials; the building block building method is adopted; the thickness of the thermal-insulation layer of the wall body can be designed according to local conditions; the slits in the wall body are reduced; the poor thermotechnical performance of a well-frame building is improved effectively; the construction is simple; the construction cost is low; the purpose of ecological and environmental protection is realized; and the local advantages can be played.

Description

[0001] Field [0002] The invention relates to a method for enhancing the thermal insulation performance of a well dry wall with light raw soil materials and a composite thermal insulation wall made of light raw soil materials, belonging to the technical field of construction. Background technique [0003] In the construction of traditional well-dried buildings, the thermal insulation effect of the building is mainly achieved by the tight connection of wood. To achieve this purpose, large straight wood is usually required to meet the requirements, and the consumption of high-quality wood is relatively large. Affected by the decline in the quality of forest resources, the existing well-dried buildings are mostly made of fast-growing materials, which have small diameters and large curvatures. The gaps in the constructed well-dried walls are larger than those of traditional well-dried houses. The thermal insulation performance is poor, and the consumption of firewood for heating ...
