Matters needing attention in brick masonry construction?

(1) The foundation wall is staggered from the upper wall: the bottom of the foundation brick is stacked correctly, and both sides of the big corner should be equal. Back to the front of the wall, check whether the axis and edge are correct. If the deviation is small, it can be corrected in the foundation part, and it is not allowed to retreat or go out above the moistureproof layer.

(2) Drift joints of drywall: When arranging bricks, the vertical joints must be evenly arranged, and the height of the first step should be completed. Every 2 meters, the elastic line should be hung straight in the vertical position of the brick, and the elastic line should continue to be hung straight in the second step. The length of the seven parts should be consistent from bottom to top, and the upper window must be kept vertical with the lower window when it is divided.

(3) Uneven size of mortar joint: ensure that the elevation of pole is consistent, and the mortar joint should be uniform when setting the corner. When bricklaying, small threads should be tightened to prevent one layer of threads from loosening and the other layer from tightening.

(4) The vertical joints of commercial windows become flexible: in dry wall-building, in order to make the walls and piles between windows arrange neatly, the broken part is arranged in the middle or inconspicuous position, and the first row of bricks on the lintel shall not be flexible at will.

(5) Brick wall arching: When building the external brick internal formwork wall, 6×12× through holes shall be left between windows and on the upper, middle and lower sides of the wall on both sides of the seismic column, and the external wall of the seismic column shall be padded with wooden formwork and firmly connected with the large formwork with blue bolts. Concrete shall be poured in layers, and the vibrating rod shall not directly contact the external wall. Three-skin 12㎝ Brick wall outside the floor ring beam should also be strengthened seriously. If the brick wall is found bulging during vibrating, it should be demolished and rebuilt in time.

(6) Rough mixing wall: tongue ash is not scraped completely, and half a brick is used intensively, resulting in joints; The deviation on the back of thick brick wall is large; Brick walls crisscross to form spiral walls. Half a brick should be scattered on the larger surface of the wall. The first skin brick on the first floor or floor should check the elevation and height of the skin pole to prevent the spiral wall from being built at the top. Thick brick walls should be hung by hand.

(7) The masonry at the constructional column does not meet the requirements: the constructional column wall should be built into a big horse tooth and set with Rachel bars. Both sides should retreat from the foot of the column. When the cutting depth is 12㎝, it is advisable to put one skin 6㎝ from the top first, and then put the other skin into 12㎝ to ensure concrete pouring.
