Embodiment Construction
[0027] The construction and operation of existing building door and window frames and gaps between openings are manually filled, and the filling materials basically cannot be put in place at one time, requiring workers to repeatedly smear and repair, which is time-consuming, labor-intensive and material-intensive, with low efficiency, high cost, and inconsistent standards , The plugging is not dense. The main innovation of the present invention is: before sealing, the hole is processed so that the width of the gap between the door and window frame and the edge of the hole is within the preset range, and the filling mortar preparation process is strictly controlled according to the mass ratio of mortar and water, so that the prepared filling mortar is suitable for use. Standardized filling with pressure fillers, these instrumentalized and standardized operations ensure the compactness and cohesion of the joints, and greatly reduce the production cost.
