The glue gap is plugged by a foam rod, so that the glue gap is straight and reserved with the glue thickness of 2.5-3.5 mm. It must be sealed with weather-proof glue to prevent gas permeation and rain leakage. Before the glue is applied, masking paper with the width of 20mm is stuck on two sides to prevent stone pollution, a spatula with a round opening is used for trowelling the surface of the glue line after the glue is injected, so that the glue line has a concave feel of 2-3mm, the aesthetic feeling is improved, and the redundant glue is removed. Care is taken to maintain after glue injection, and dust and scratches are not polluted before the glue is not fully hardened.
According to the invention, ninety percent of welding workload is controlled on the ground through the semi-unit installation method, so that the welding quality is effectively ensured, the influence of weather on the construction period is reduced, the cross keels form a shared system, the installation quantity is reduced, the adjustment is more convenient, the position of the hanging assembly can be flexibly adjusted, the hanging assembly has very reliable stability after being fixed, the installation precision and the installation quality are ensured, and the beautiful appearance of the stone outer facade is greatly improved.
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the invention in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present invention.
