[0028] like Figure 1-2 The shown heat storage and heat preservation skeleton type greenhouse wall includes an inner layer 1, an intermediate layer 2 and an outer layer 3 arranged sequentially from the inside to the outside, and the inner layer 1, the middle layer 2 and the outer layer 3 are all made of hollow brick The inner layer 1, the middle layer 2 and the outer layer 3 are fastened and connected by tie bars 6; the middle layer 2 and the outer layer 3 are insulation layers, and the pores of the hollow brickwork The upper and lower alignment forms an air circulation channel 7; the inner layer 1 is a heat storage layer, and the pores of the hollow bricks are aligned up and down, and the pores are filled with a heat storage material 4, and the heat storage material is desert sand or soil .

[0029] The wall of the present invention adopts a three-layer structure, wherein the inner layer 1 is filled with heat storage materials, which can improve the heat storage performance ...

Embodiment 2

[0032] On the basis of the technical solution of Example 1, the wall also includes the following technical features:

[0033]The hollow bricks are prepared from the following raw materials in parts by weight: 300 parts of cement, 15 parts of rice husk powder, 3 parts of nano-silica, 800 parts of sand, 300 parts of industrial waste, 3 parts of water reducing agent, modified 9 parts of straw, 9 parts of metakaolin, and 150 parts of water.

[0034] The preparation method of described hollow brick is as follows:

[0035] S1. Collect straw and industrial waste, sieve, and reserve;

[0036] S2. Put the collected and sieved stalks into an 8% NaOH solution by mass, soak for 8 hours, then wash and dry; then spray 3% water glass on the dried stalks , to obtain modified straw.

[0037] S3. Mix and stir cement, rice husk powder, nano-silica and sand for 3 minutes, then add industrial waste residue and metakaolin, and stir for another 3 minutes, then add water, water reducing agent and ...

Embodiment 3

[0045] On the basis of the technical solution of Example 1, the wall also includes the following technical features:

[0046] The hollow bricks are prepared from the following raw materials in parts by weight: 400 parts of cement, 80 parts of rice husk powder, 20 parts of nano silicon dioxide, 1000 parts of sand, 400 parts of industrial waste residue, 4 parts of water reducer, modified 12 parts of straw, 12 parts of metakaolin, and 200 parts of water.

[0047] The preparation method of described hollow brick is as follows:

[0048] S1. Collect straw and industrial waste, sieve, and reserve;

[0049] S2. Put the collected and sieved straw into 10% NaOH solution by mass, soak for 8h, then wash and dry; then spray the pure acrylic acid polymer solution of 3% by mass after drying on the straw to obtain the modified straw.

[0050] S3. Mix and stir cement, rice husk powder, nano-silica and sand for 3 minutes, then add industrial waste residue and metakaolin, and stir for another...

Abstract

The invention discloses a heat-storage and heat-preservation framework type greenhouse wall, and relates to the technical field of constructions. The heat-storage and heat-preservation framework type greenhouse wall comprises an inner layer, a middle layer and an outer layer which are sequentially arranged from inside to outside, and the inner layer, the middle layer and the outer layer are all formed by laying hollow bricks; the middle layer and the outer layer are thermal insulation layers, and holes of the hollow bricks are aligned up and down to form an air circulation channel; and the inner layer is a heat storage layer, the holes of the hollow bricks of the heat storage layer are vertically aligned, and the holes are filled with heat storage materials. The heat-storage and heat-preservation framework type greenhouse wall is a three-layer structure body formed by building the hollow bricks made of special materials, the inner layer is filled with the heat storage materials, the heat storage performance of the wall can be improved, the middle layer and the outer layer are provided with the air circulation channel, and the good heat insulation and heat preservation effect can be achieved. The heat-storage and heat-preservation framework type greenhouse wall can improve the regulation and control capability of the greenhouse wall on a thermal environment in a greenhouse and the utilization rate of the greenhouse on solar energy.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a heat storage and heat preservation skeleton type greenhouse wall. Background technique [0002] The wall plays the role of load bearing, heat preservation and heat storage in the greenhouse. However, the walls of the existing solar greenhouses are mainly full-mound and solid clay brick walls. The mound-type wall occupies a large area, the land utilization rate is low, the soil is alkaline, and the wall is easy to crack, which reduces the thermal insulation performance, etc. question. Clay brick wall has good alkali resistance and durability, but it will cause serious waste of soil resources. At the same time, 240 or 370 clay brick wall is not suitable for winter use due to its small wall thickness and poor thermal insulation performance. In order to reduce the cost of the greenhouse, improve the thermal insulation performance of the greenhouse and increase the economic inco...
