Example Embodiment
[0051] Example one
[0052] The prefabricated wall of this embodiment, such as figure 1 , figure 2 with image 3 As shown, it includes a steel cage located on the floor. The reinforcement cage includes a longitudinal main reinforcement 1 and a stirrup 2 fixed on the main reinforcement, and a first disassembly-free thermal insulation template 3 is fixed on the outer surface of the reinforcement cage. A limit ring 4 and a positioning steel pipe 5 extending along the length direction of the main reinforcement 1 are arranged in the reinforcement cage.
[0053] The positioning steel pipe 5 is set in the limit ring 4. The positioning steel pipe 5 in the reinforcement cage on the upper floor and the positioning steel pipe 5 in the reinforcement cage adjacent to the lower floor are connected by positioning pipe sleeves. The butt-butting main reinforcements 1 of the reinforcing steel cages on the adjacent floors are fixed by welding, and the concrete poured on-site is solidified in the re...
Example Embodiment
[0068] Example two
[0069] The prefabricated wallboard of this embodiment is an improvement based on the first embodiment, such as Figure 4 to Figure 11 As shown, the difference from the first embodiment is that it includes two concrete panels 6 arranged front and rear. Between the two concrete panels 6 is fixed a positioning steel pipe column 7 and a thermal insulation material layer 8 filled with cement-based cement. The two concrete wall panels 6 and the thermal insulation material layer 8 are connected and fixed by connecting pins 9.
[0070] Each prefabricated wall panel is provided with a ring beam steel pipe 10 fixed at the top of the positioning steel pipe column 7, and the ring beam steel pipe 10 is provided with perforations. The upper end of the positioning steel pipe column 7 does not exceed the prefabricated wall panel body, and the lower end of the positioning steel pipe column 7 extends out of the precast The wall panel body is inserted into the steel tube hole of...
