Embodiment 1
[0050] Such as figure 1 The rammed earth wall body shown includes an insulation layer 10 , a reinforcement grid layer 20 and a rammed earth wall layer 30 .
[0051] The thermal insulation layer 10 is arranged in the middle of the width direction of the rammed earth wall body, extends along the length direction of the rammed earth wall body, and plays the role of thermal insulation. The distance between the upper, lower, left and right four edges of the insulation layer 10 and the upper, lower, left and right four outer surfaces of the rammed earth wall is greater than or equal to 200 mm to prevent the insulation board from cracking the wall caused by the edge. The thickness of the insulation layer may be 40mm-90mm. The insulation layer can be a polyurethane board.
[0052] Such as figure 1 with figure 2 As shown, the two reinforcement mesh layers 20 are symmetrically arranged on both sides of the insulation layer 10 and are parallel or roughly parallel to the insulation l...
Embodiment 2
[0057] Such as image 3 with Figure 4 The rammed earth wall shown includes an insulation layer 10 , a reinforced grid layer 20 , a rammed earth wall layer 30 , door and window openings 41 and prefabricated concrete lintels 42 .
[0058] Wherein, the setting method of the insulation layer 10 , the reinforcement grid layer 20 and the rammed earth wall layer 30 is consistent with that in Embodiment 1, and will not be repeated here.
[0059] The door and window hole 41 is arranged at the position that needs to open a window or open a door. Prefabricated concrete lintels are arranged above the door and window openings 41 to share the weight of the rammed earth wall above the door and window openings, so as to maintain the shape of the door and window openings without or reduce deformation. Such as Figure 4 As shown, the length of the precast concrete lintel 42 is longer than the length of the door and window opening 41 , and optionally, the two sides of the precast concrete li...
Embodiment 3
[0062] This embodiment provides the construction method of the rammed earth wall with door and window openings described in Embodiment 2.
[0063] 1. Materials
[0064] 1) Raw materials for the rammed earth wall layer 30:
[0065] Including gravel, sand, cement, waterproofing agent and water. In some cases, in order to obtain the texture effect of the rammed earth wall, color powder can be added to form the texture effect of interlacing different colors.
[0066] Stones include large stones with a particle size of 20-60mm and melon seeds with a particle size of 10-25mm. The stones cannot contain sand and other loads. Two kinds of stones with different particle sizes are used after blending to make the porosity as small as possible.
[0067] The medium-sized washed yellow sand is used for the sandy soil. The proportion of coarse sand in the yellow sand is greater than that of fine sand, and it cannot contain grass roots and other debris. Sand with a particle size of 0.25 to...
