Abstract

A construction method for a connection joint of a prefabricated sandwich side fascia specially comprises the steps of S1, hoisting the prefabricated sandwich side fascia, positioning the bottom edge, erecting an oblique support and leveling the prefabricated sandwich side fascia; S2, hoisting a superposed beam, erecting a vertical support, installing a horizontal fixed support, and fixing the superposed beam to the prefabricated sandwich side fascia; S3, hoisting and positioning a superposed floor slab; S4, making a erection bar penetrate through a connecting cable in a shear key groove, and connecting the erection bar with a stirrup of a superposed beam cast-in-situ layer fixedly; S5, placing a shear key additional rebar in the shear key groove and a superposed floor slab cast-in-situ layer; S6, arranging superposed floor slab cast-in-situ layer reinforcing mesh panels, pouring cast-in-situ concrete, and conducting curing and molding; S7, dismantling a bottom edge positioning device and the oblique support of the prefabricated sandwich side fascia. Compared with the prior art, the construction method for the connection joint of the prefabricated sandwich side fascia has the advantages that rebar bending is avoided on a construction site, construction efficiency is improved, and the rebar processing and construction technology is simplified.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for connecting nodes of prefabricated sandwich exterior wall panels. Background technique [0002] In the prior art, the inner leaf plate of the prefabricated sandwich outer wall panel is pre-embedded with extended anchoring steel bars, and the outward anchoring steel bars are in an "L shape" during transportation and construction. outside the plate and in the plane of the inner leaf plate. The construction method of the connection node of the prefabricated sandwich exterior wall panels in the prior art is as follows: first hoist and position the prefabricated sandwich exterior wall panels during construction; then hoist the laminated beam and position it on the prefabricated sandwich exterior wall panels; The floor slab is positioned on the laminated beam; the outstretched anchor bars of the prefabricated sandwich exterior wall panels are ...
