How to build a partition wall indoors

1, block watering: it must be watered and wetted the day before masonry, and it is generally appropriate to soak the four sides of 1.5cm, and the water content is 10% ~ 15%. Dry blocks shall not be used to build walls at room temperature, and blocks saturated with water shall not be used to build walls in rainy season.

2. Mortar mixing: the mixture ratio of mortar should be weight ratio, the measurement accuracy of cement should be 2%, and the sand content should be controlled within 5%. Mechanical stirring shall not be less than 65438 0.5 minutes.

3. Wall-building: Brick arrangement and bottom swing (dry swing): According to the played position lines of doors and windows, carefully check the dimensions of the stacks between the walls and windows. Block selection: select blocks with neat edges and corners, no cracks and basically the same specifications. Slab angle: Slab angle shall be set before laying, and the slab angle shall not exceed five layers at a time. The big angle of the new plate should be hoisted and tightened in time. If there is any deviation, it should be repaired in time. When setting the angle, carefully control the brick layer and elevation of the skin pole, control the size of the mortar joint, and make the horizontal mortar joint uniform. After the big horn board is finished, review it again. After the flatness and verticality completely meet the requirements, hang the line to build a wall. Hanging line: several people use a through line on the long wall, with several branch points in the middle, and the small line should be tightened. Each layer of block adopts external hanging thread by hand to take care of the flatness on both sides of brick wall and lay the foundation for the next working procedure to control the plastering thickness. When laying the first floor, when the mortar joint is greater than 30㎜, it shall be leveled with pisolite concrete, and it is forbidden to level with mortar. When the top of wall masonry is 50 ~ 80 ㎜, it shall be filled with expansive concrete. Masonry, block should be flat, masonry must be along the line. "Upper heel line, lower heel edge and left and right neighbors should be flat." Generally, the thickness of horizontal mortar joint and the width of vertical mortar joint are 12mm, but not less than 10mm and not more than 15 mm. ..
