Referring to fig. 1 and 2, fig. 1 is a flow chart illustrating a method for repairing leakage of a light partition board for an exterior wall of an assembly type building according to an embodiment of the present invention; FIG. 2 is a cross-sectional view of the components within the splice seam.
The embodiment of the invention discloses a leakage maintenance method of a light partition board for an external wall of an assembly type building, which comprises the following steps:
the first step is as follows: cutting stress relief grooves 1 along the wallboard intersection joints or cracks;
specifically, a cutting machine is used for cutting a stress release groove 1 at a joint seam or a crack between a light partition board and a beam-slab column, wherein the width range of the stress release groove 1 is 1-5 mm, and preferably 2-4 mm.
The second step is that: coating an interface treatment layer along the edge of the stress release groove 1;
