The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, Shanghai real estate dwelling house project, 14 layers on the ground of experimental projects, underground 1 layer, building height is 42.50m, adopts the plug-in prefabricated reinforced concrete side fascia 1 of cast-in-situ concrete frame-shear wall structure, wallboard nominal thickness 160mm, the integrated facing tile of plate face, conventional exterior wall internal insulation way is adopted in insulation.Project is built up follow-up investigation and is found no breakthrough.
As depicted in figs. 1 and 2, present embodiment comprises: side fascia 1, sealing rod 2, PVC plastic sheet 3, joint filling layer 4, sealant 5 and mozzle 6, wherein: the inside of side fascia 1 is provided with the decompression cavity 7 of level, sealing rod 2 is positioned at side fascia 1 and is connected with the decompression cavity 7 of some blocks of adjacent side fascias 1, PVC plastic sheet 3, joint filling layer 4 and sealant 5 are set in turn in the other end of decompression cavity 7 from outside to inside, and mozzle 6 is positioned at the outside of side fascia 1 and is connected with sealant 5.
