Detailed Description
As shown in fig. 1-3, a cracking-resistant wall surface coating structure comprises a separation net 2 covered on the surface of a wall body 1 and fixedly connected with the wall body 1, wherein a coating layer is coated on the surface of the wall body 1 in the grids of the separation net 2;
the separation net 2 is formed by splicing net strips 21 with rectangular cross sections, the net strips 21 are made of elastomer materials, and one side surface of each net strip is arranged by being attached to the surface of the wall body 1; the material of the net strip 21 is selected from elastomer material so that the expansion and contraction of the coating layer are buffered and the water seepage is not caused.
The coating layer is divided into an expanded cement layer 3 and a putty layer 4 from the surface of the wall body 1 to the outside in sequence, and the total thickness of the coating layer is not less than the thickness of the separation net 2. The expanded cement layer 3 cannot be replaced by ordinary or white cement, otherwise cracks may occur between the paint layer and the separation net 2. In addition, the putty layer 4 should also be doped with expansion cement, in this embodiment, the putty layer 4 is obtained by preparing a mixed putty paste from water-resistant putty, expansion cement and 108 glue according to a ratio of 1:0.5:0.8 and then brushing the mixed putty paste, and the mixed putty paste is prepared by the following method: adding a small amount of 108 glue, slowly pouring putty powder and cement, stirring, adding 108 glue while stirring, standing for 10-15 min, and stirring again
The separation net 2 is connected with the surface of the wall body 1 through adhesive sticker. The purpose of sticking the separation net 2 on the wall is to temporarily fix the separation net before painting, and the separation net 2 is not connected with the wall 1 by self-adhesive.
The net strips 21 are weather-proof rubber tubes with rectangular cross sections, and the rubber tubes can expand and contract more effectively than rubber strips, and materials are saved.
