Problems solved by technology

[0002] After the existing frame structure infill wall is built, fiber mesh is often used to lay and paste the joint between the infill wall and the frame structure, and then directly painted. Since the infill wall is different from the frame beam and column material, the shrinkage rate is different. After completion, cracks are prone to appear at the junction of the two (the probability of occurrence is more than 40%)

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with specific embodiments.

[0020] The whitewashing method of filling wall of the present invention is as follows:

[0021] 7 days after the masonry of the filling wall in the frame project is completed → plaster the ash cake → after the joints of the beams, columns (that is, the frame structure 2) and the filling wall 1 are blocked with expanded fine stone concrete, lay a layer of alkali-resistant mesh cloth 3 (distance The lap joint width of the seam side is not less than 150mm) → the first bottom copying and maintenance → the bottom copying is 70% dry, and the second layer is the surface layer construction. Lay a layer of grid cloth 3 on the surface of the mortar at the junction of the column and the filling wall, the paving method is the same as before → calender the surface with an iron trowel, press the alkali-resistant mesh cloth into the cement slurry → maintain the whitewash layer.

Abstract

The invention discloses a method for whitewashing a filler wall. The method comprises the steps of providing a whitewash ash cake, conducting primary bottom layer maintenance, conducting secondary surface layer construction and conducting surface pressing and polishing. Before the primary bottom layer maintenance is conducted, a gridding cloth is laid at the combined position of the filler wall, a beam and a column, and before the surface pressing and polishing is carried out, a gridding cloth is laid on the surface of slurry at the combined position of the filler wall,the beam and the column. The method can effectively reduce surface cracks caused due to the fact that the materials on the two sides of the combined position are different, and secondary maintenance cost for crack repair is omitted.

Description

technical field [0001] The invention relates to a painting method for filling walls. Background technique [0002] After the existing frame structure infill wall is built, fiber mesh is often used to lay and paste the joint between the infill wall and the frame structure, and then it is directly painted. Since the infill wall is different from the frame beam and column material, the shrinkage rate is different. After completion, cracks are very likely to appear at the junction of the two (the probability of occurrence is more than 40%). Contents of the invention [0003] The purpose of the present invention is to provide a painting method that reduces or avoids surface cracks in order to solve the defects in the prior art. [0004] In order to achieve the above object, the present invention provides a method of painting a filled wall, including painting ash cake, first pass of bottom copy curing, second pass of surface layer construction, and surface calendering; ...
