[0026] Embodiment:

[0027] As shown in the accompanying Figure 1 to the accompanying Figure 3 , mainly including three layers of structure, as follows:

[0028] Bottom layer: glass fiber mesh reinforced cement thin plate 1, the thickness is changed from more than 4cm to 0.5cm-1cm, which greatly reduces the pouring cost of concrete;

[0029] Middle layer: a plurality of straw soil blocks 2 distributed at equal intervals, longitudinal beams 5 are poured on the left and right sides of the straw soil blocks 2 through a mold, and transverse beams 4 are poured on the front and rear sides of the straw soil blocks 2 through a mold, the straw soil blocks 2 replace the existing foam filling block, which has the following effects:

[0030] 1. In the processing and manufacturing process, the foam filling block will move during the pouring of concrete because of its light weight, which cannot accurately meet the production process requirements, resulting in uneven floor slabs, even local stress concentration problems, and cracking. However, during the manufacturing and processing process of the straw soil block 2, the weight of the straw soil block 2 will be larger than that of the foam filling block, and the adhesion performance of the straw soil block 2 and the glass fiber mesh reinforced cement thin plate 1 is good, which will not move and float, which is beneficial to industrialized production, so that the movement will not occur during pouring, and the requirements of industrialized production can be met;

[0031] 2. The production material of the straw and soil building block 2 is mainly straw and soil, which can be locally sourced and has low cost, and is conducive to the secondary waste utilization of straw, can avoid burning straw, and is conducive to environmental protection;

[0032] 3. The straw and soil building block 2 is made of soil, which is better in sound insulation, and the straw and soil building block 2 can also achieve the effect of purifying air.

[0033] 4. The straw and soil building block 2 not only meets the heat preservation and insulation requirements, but also has better sound insulation effect than foam blocks.

[0034] Meanwhile, prestressed steel bars 6 are arranged between the longitudinal joists 5, which is conducive to improving the application span of the floor, and the horizontal rib through holes 7 are arranged at the upper end of the horizontal rib beams 4, and the horizontal rib through holes 7 and the prestressed steel bars 6 are distributed in a staggered manner, so that the concrete poured in the post-poured concrete layer 3 is also poured into the several horizontal rib through holes 7, making the connection between each floor and the poured concrete layer more stable, and the horizontal rib through holes 7 and the prestressed steel bars 6 ensure the strength of the composite floor;

[0035] As shown in the accompanying drawings Figure 3 It can be seen that the straw and soil building block 2 is inverted conical, and the width difference between the upper and lower end faces is 5mm, which is conducive to increasing the bearing capacity of the floor, and because the width difference is not large, the width difference is enlarged in the accompanying drawings Figure 3 There is no such large difference in practice.

[0036] The bulk density of the straw and soil building block is less than 650kg / m 3 , and the thermal conductivity is less than 0.08.

[0037] Top layer: post-poured concrete layer 3, which can also be greatly reduced in thickness, reducing the cost of concrete pouring.

[0038] In the case of increasing the thickness of the middle layer, the thickness of the bottom layer and the top layer is reduced, which ensures the overall processing size and meets the requirement of structural strength.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
