Firstly, connecting the prefabricated floor 04 with an embedded part at the top of the lower prefabricated wall panel 03, and then hoisting the upper prefabricated wall panel 03. The length of the connecting plate is greater than the thickness of the prefabricated floor 04, the top of the connecting plate 7 exceeds the splicing seam between the upper prefabricated wall plate 03 and the prefabricated floor 04, and the bottom of the connecting plate exceeds the splicing seam between the lower prefabricated wall plate 03 and the prefabricated floor 04; the top of connecting plate is connected with the built-in fitting in the prefabricated wallboard 03 of upper strata, and the bottom of connecting plate 7 is connected with the built-in fitting in the prefabricated wallboard 03 of lower floor. Because the upper-layer prefabricated wall panel 03 is provided with the bottom rabbet 11, when the upper-layer prefabricated wall panel 03 is connected with the prefabricated floor slab 04, the bottom rabbet 11 of the upper-layer prefabricated wall panel 03 is matched with the top rabbet 10 of the lower-layer prefabricated wall panel 03 to form a limiting structure, and the bottom rabbet 11 of the upper-layer prefabricated wall panel 03 is equivalent to a mounting groove 08 for accommodating the end parts of a connecting plate and a pull rod.
In other embodiments, the first member is a precast beam, the second member is a precast wallboard, and the top of the precast wallboard is connected with the precast beam through a connecting assembly to form a precast wallboard point hanging structure.
Example 4
Referring to the schematic diagram of fig. 10, in the connection node of the prefabricated components in this embodiment, the second component is a prefabricated parapet 05, the first component is a prefabricated floor slab 04, the embedded end of the embedded part 8 is embedded in the bottom of the prefabricated parapet 05, and the bottom of the prefabricated parapet 05 is connected with the prefabricated floor slab 04 through the connection assembly 01.
In another modified embodiment, the bottom of prefabricated parapet 05 is also provided with a step rabbet. According to the arrangement, a limit structure is formed between the step rabbet at the bottom of the prefabricated parapet and the top rabbet of the prefabricated wallboard at the lower layer, so that rainwater at the outdoor side can be prevented from entering the abutted seams; and the bottom rabbet of the prefabricated parapet is equivalent to a mounting groove for accommodating the ends of the connecting plate and the pull rod.
The installation steps of the connection node between the prefabricated parapet and the prefabricated floor slab in this embodiment are substantially the same as the installation steps between the prefabricated wall panel and the prefabricated floor slab in embodiment 3, and are not described again here.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application and not for limiting the protection scope thereof, and although the present application is described in detail with reference to the above embodiments, those of ordinary skill in the art should understand that: numerous variations, modifications, and equivalents will occur to those skilled in the art upon reading the present application and are within the scope of the claims as issued or as granted.
