T-wall masonry method

1, when the thickness of brick wall is more than one brick, cis-butyl or plum blossom ding masonry method can be adopted. Brick wall thickness is 3/4 brick, and two sides are laid flat. Curved brick walls can be built of all masonry.

2. Masonry of brick wall (brick masonry) should be staggered, internal and external _, with straight mortar joint and full mortar. The thickness of horizontal mortar joint and the width of vertical mortar joint are generally 10mm, but they should not be less than 8mm or greater than 12 mm. ..

3. The corner and junction of the brick wall should be laid at the same time, and the temporary breaks that cannot be laid at the same time and must be kept should be made into oblique if. The inclined length of solid brick wall should not be less than 2/3 of the height.

If it is really difficult to leave oblique seams at temporary breaks, straight seams can also be left except at corners, but they must be made into straight seams and tied with tendons. The number of Rachel bars should be made into a positive gap per 12cm wall thickness, and Rachel bars should be added. The number of Rachel bars shall be put into the rebar with a diameter of 6mm per 12cm wall thickness, and the spacing along the wall shall not exceed 50cm, and the embedding length shall be increased.

4. The top surfaces of partition walls and infilled walls in contact with the superstructure are obliquely built with side bricks or vertical bricks.

5, each layer of load-bearing wall on top of a skin brick, application of top build by laying bricks or stones masonry.

6. Below the beam and beam pad, on the floor layer of brick masonry and the pick layer of brick masonry (overhangs, waistlines, etc.). ), masonry should be built by masonry.

What are the precautions for building walls?

1, before wall construction, you should water and wet the bricks and blocks two days in advance. Never cast-in-situ use. At the same time, it is forbidden to dry bricks directly on the wall.

2. Generally speaking, adding various plasticizers into cement mortar will greatly reduce the compressive strength of masonry. Because cement has fine fineness and good workability, it is best not to add plasticizer. If it must be added, the proportion must be determined by experiments.

3. When building walls, the height of building walls should not exceed 1.8m every day. In case of continuous rainy weather, the height of masonry wall shall not exceed 1.2m every day while strictly controlling the consistency of mortar. In addition, before calling it a day or stopping work, a row of dry bricks must be laid on the top of the wall, or covered with materials such as straw curtains to prevent mortar from being washed away by rain.

4. Generally speaking, medium sand is used for wall mortar. At the same time, the dosage of sand must be strictly controlled according to the design label of mortar. Yes, it is not allowed to increase the amount of sand used beyond the standard.
