Embodiment 1
[0073] see figure 1 with figure 2 As shown, the assembly method of the upper and lower self-insulating external walls and the floor in this embodiment includes the first shear wall 1 , the second shear wall 2 and the floor 3 . Both the first shear wall 1 and the second shear wall 2 include an outer thermal insulation layer 4 and an inner load-bearing layer 5 connected as one, and the bottom side of the thermal insulation layer 4 is longer than the load-bearing layer 5, and the top side is lower than the load-bearing layer 5; the load-bearing layer 5 is provided with steel mesh (not drawn among the figure). The top side and the bottom side of the load-bearing layer 5 are provided with prefabricated connecting beams, and connecting steel bars are arranged in the prefabricated connecting beams. In this embodiment, the connecting steel bars are stirrups; The beam 6 is provided with a first stirrup 7; the bottom side of the load-bearing layer 5 of the second shear wall 2 is a se...
Embodiment 2
[0080] refer to Figure 5 As shown, the assembly method of the upper and lower self-insulating exterior walls and floors in this embodiment includes the first shear wall 1, the second shear wall 2 and the floor 3, the first shear wall 1 and the second shear wall 2 both include an insulation layer 4 and a load-bearing layer 5; the insulation layer 4 and the load-bearing layer 5 are connected into one body, and the insulation layer 4 is a fiber cement insulation board, the two sides are wider than the load-bearing layer 5, the lower part is longer than the load-bearing layer 5, and the upper part is lower than the load-bearing layer. Layer 5. The load-bearing layer 5 is provided with a double-sided steel mesh (not marked in the figure), and the double-sided steel mesh is formed by cross-connecting longitudinal rectangular steel rings and vertical rectangular steel rings 14 .
[0081] see Figure 4 The vertical section of the external wall shear wall shows the distribution of v...
Embodiment 3
[0089] Such as Figure 4 , Figure 7 , Figure 8 As shown, the assembly method of the upper and lower self-insulating exterior walls and floors in this embodiment includes the first shear wall 1, the second shear wall 2 and the floor 3, and the structure of the assembly nodes is roughly the same as that in Embodiment 2, specifically The difference is that the positions of the longitudinal steel bars 10 are different, and the specific description is as follows:
[0090] see Figure 7 As shown, in this embodiment, the longitudinal steel bar 10 is arranged inside the rectangular steel bar anchor ring 15 and is close to the surface of the load-bearing layer 5, that is, the rectangular steel bar protruding from the top side of the load-bearing layer 5 of the first shear wall 1 In the anchor ring 15, two first longitudinal steel bars 19 are arranged close to the surface of the load-bearing layer 5, and in the rectangular reinforcement anchor ring 15 protruding from the bottom sid...
