Please ask the construction technicians to explain what is "One Shun One Ding" and what is "Three Shun One Ding"? What are the masonry methods?

Yishun Yi Ding: Also known as "full brick strip", it refers to the way of laying brick by brick alternately.

Sanshun Ding Yi: Three-skin brick and one-skin brick alternate, and the vertical mortar joint between the upper and lower skin of the brick is staggered 1/2 brick length; The vertical mortar joint between the upper and lower skins of cushion brick and butyl brick is staggered 1/4 brick length.

Masonry methods: Shun Shun, two sides flat, Ding Quan, Yishun Yi Ding, Ding Meihua and Sanshun Yi Ding.

Advantages and disadvantages:

Zhongtian: It is suitable for building walls with a thickness of 3/4 bricks (178mm).

Ding Quan: It is suitable for building walls with brick thickness (240mm).

Integral molding: the advantages are good lap joint, no through seam, strong integrity and wide application. The disadvantage is that the vertical seam is not easy to align; Bricks must be cut at the corner of the wall, T-joint, doors and windows, so the masonry efficiency is limited. This method is the most common and has low technical requirements for workers. Suitable for building a brick or multiple thick walls.

Plum blossom ding: suitable for thick brick walls.

Sanshun Dingyi: This masonry method is the most difficult, but the strength of the wall is the highest. Suitable for building a brick or multiple thick walls.

The variety and label of cement used in masonry mortar should be selected according to the masonry position and environment. Before cement is put into use, its strength and stability should be reinspected in batches. The inspection lot shall be made by the same manufacturer with the same batch number.

The silt content of sand for mortar shall meet the following requirements: for cement mortar and cement mixed mortar with strength grade not less than M5, it shall not exceed 5%; For cement mortar with strength grade less than M5, it should not exceed10%; Artificial sand, mountain sand and extra-fine sand should be tried to meet the technical requirements of masonry mortar.
