How to rectify the imperfect grid seal?

(1) When pouring slabs or columns, directly embed benzene slabs with the same seam width to naturally form horizontal and vertical thermal insulation belts. (2) Clean up the garbage at the joints in time as the acceptance process; During the technical handover, the operators are required to avoid dropping bricks and concrete mortar residues into the joints as much as possible. (3) Before installing the outer corner brace, waterproof work should be done along the deformation joint to prevent moisture seepage, wall pollution and paint falling off. (4) Before installing the cover plate of indoor horizontal deformation joint, waterproof work should be done along the horizontal joint, and the protective layer should be spread to both sides of the wall or floor not less than150 mm. The gaps on both sides of the cover plate are sealed. (5) The traditional deformation joint gusset plate is generally galvanized iron sheet, and the plaster between the iron sheet and the wall is uneven and rough, which affects the appearance; In the construction process, we use aluminum-plastic plate or aluminum alloy as deformation joint gusset plate, and there are two kinds of gusset plate materials: one with V-shaped or W-shaped corners can directly fix gusset plate and external corner grooves on both sides of the wall; The other is a straight plate. During installation, the external corner groove is fixed on the wall. One side of aluminum-plastic plate and aluminum alloy plate is fixed, while the other side is not fixed, so as to meet the requirements of thermal expansion and cold contraction. This method is simple to install and can increase the number of buildings.
