Acceptance criteria of vertical plane

The verticality is 6mm, and the levelness of 4m shall not exceed 10mm.

Basis: According to the Code for Acceptance of Construction Quality of Masonry Engineering (GB50203-2003), the allowable error of surface flatness of brick masonry is 5mm, the allowable error of mixed water wall is 8 mm ... and the allowable deviation of verticality of each floor is 5 mm; Total height ≤ 10m, and allowable deviation of verticality is10mm; ; Total height > > 10m, and allowable deviation of verticality is 20mm.

Sharp tools can do a good job. Anyone who builds it himself knows the importance of tools. As far as the traditional wall-building project is concerned, a triangular or quadrilateral trowel is needed first.

Triangular trowel is more useful, but it needs some practice before use. Most beginners had better use a four-corner trowel first, which is better for plastering.

In addition to the trowel, you also need a wall hammer, chisel and double-sided hammer. In order to ensure accurate measurement, folding ruler, tape measure, wall line, hammer and spirit level are all indispensable.

Besides trolleys, shovels and hoes, 2~3 mortar buckets and several other buckets are needed. Electric mixer is also essential, through which concrete and mortar are mixed.

Modern large-scale masonry is produced in one block, so the grouting work of mortar joint is not considered. If the mortar joint is grouted, the so-called "mortar skateboard" can be used, which can not only save labor time, but also make the mortar joint uniform.
