1. Brick processing (dry pendulum, silk seam)
To solve the problem of dust pollution and noise pollution, brick processing is performed outside the construction site. Only simple procedures such as "truncation" are performed on site. Each batch of construction bricks can only be processed after passing the laboratory test. During processing, qualified "official bricks" should be made first, and batch processing can only be performed after unified standards. A quality inspector is set up at the processing site to take charge of the job to ensure compliance. The processed bricks are packed before entering the site, and the loading and unloading trucks have a special person to reduce losses.
Material requirements Quick lime should be selected at the end of the block without 1: 1 or more impurities and stones. The ash should be splashed twice, and the sprinkler should be even and moderate, so that the quick lime can be fully digested and matured, and the water pipe must not be directly inserted into the ash pile. Fill the water at any time when turning over the pile, pick out the stones, pass the splashed ash through a 5mm sieve, and then laminate the slurry with a weight ratio of white ash: blue ash 100: 13. The ash block should be fully matured, no stone, the pouring slurry should be carried out in turn for each layer, every 70mm thick is a layer, and the green slurry should be thick. When the ash pile enters the rainy season, cover measures are taken to prevent rain.
3. Use "Five Grilled Skins"
In the process of masonry, there should be a special person to "cut the material" to supplement the unfinished matters in the brick cutting at any time.
4, elastic line, kind of work
First clean the grass roots, and then use the ink line to pop up the thickness, length, and position and shape of the character. According to the design requirements, according to the arrangement of the brick seams (such as the Sanshun-Ding row method), the test pendulum is “like living”. Of course, in order to determine the specifications of the "five grilled skin" bricks, the real sample work should be performed before cutting the bricks, and the sample work at this time is only to verify and make appropriate adjustments.
5. Tether and feet
The two vertical lines tied at both ends are called "drag lines". Two horizontal lines should be tied between the pull lines. The lower line is called the "lying line" and the upper line is called "hanging line" (remove it after hitting the stand rule). Before laying the first layer of bricks, check whether the grass-roots level (such as Taiming, earth lining stones, etc.) is uneven, and if there is any deviation, it should be solidified with a trowel, called a footing. "
6, put the first-layer of brick, playing stand
Laying on the footed Taiming, the vertical and horizontal joints of the masonry hang ashes, that is, "dry pendulum." When there is a pillar stone, the brick must be cut according to the shape of the pillar drum. The specific method is to place the brick on the masonry position, and then open the ruler,-while sliding along the top of the pillar,- Make marks on the brick, and then cut by the cutter according to the marks. After placing the bricks, you should use a flat ruler to perform a "scoring rule" one by one. The method of hitting a standing ruler is to bring the bottom of the flat ruler board close to the ink line of the brick wall that pops up from the foundation, the middle line to the horizontal line, and the top line to the cover line (also called the standing line). Then check whether the upper and lower corrugations of the brick are also close to the flat ruler. If they are not close or the top ruler, they must be corrected. Standing feet can also be played horizontally, and you can hit a few more layers to ensure a good start.
7, back, fill
If only the outer skin is ten pendulums, the inner skin must be built with rough bricks and mortar, which is called "back inside". For example, when the inner and outer skins are dried at the same time, the gap in the middle must be filled with rough bricks, that is, "stuffing". Whether it is the back or filling, it should be as consistent as possible with the height of the ten pendulum bricks. For example, due to the different specifications and construction methods of the bricks, it is not possible to maintain each layer. Level the skin brick once. In fact, when determining the specifications of the material in the back and the size of the chopped bricks, it should be noted that it will not cause trouble to the construction. The back or stuffing bricks should not be close to the ten pendulum bricks. It is necessary to leave an appropriate "paste mouth". The width of the mouth should be 1 to 2 cm.
8. Grouting and wiping
During the grouting, care should be taken not to have emptiness, but also to avoid excessive, otherwise the bricks will be stretched. After the littering is finished, the mortar floating on the bricks is scraped off with a squeegee board, and then the grouts filled with the mortar are wiped with a trowel ash, that is, "wiping line", also known as "lock".
9, the trip
After the first grouting, the upper part of the "grinding head" mortar brick is used to grind away, which is a brake. Brake trip is to lay down the bottom-the bricks can be tightly connected, so you should also pay attention not to brake into a local low-lying.
10, layer by layer
In addition to not standing on each floor in the future, masonry should be done in accordance with the above requirements. When placing the brick, the "upper heel and lower heel edge" should be achieved, that is, the upper edge of the brick is based on the horizontal line, and the lower edge is based on the upper edge of the bottom brick. When laying, the edges that are better cut and ground should be facing down, and the defective edges should be facing up, because the defects can be removed during braking. On the last layer, if you need to retreat to the "alkaloids" (wall shoulders), you should use bricks (shoulders facing up :). If obvious defects are found when placing the tiles, they should be cut and ground again. If the four corners of the Luming section are not on the same plane, it is allowed to protrude one corner out of the wall, that is, "throw live" is allowed, but it must not be recessed into the wall, otherwise it will not be easy to repair. The dry swing wall should be "one layer, one irrigation, three layers-wiping. Five layers, one stack", that is, each layer is grouting, but several layers of each can be wiped-secondary line, after laying several layers, it can be appropriately set aside ( It usually takes half a day) to continue building.
11. Make repairs
Repairs are done after the drywall is built, including hoe work, scoring, hoe work, and flushing.
(1) Work: Grind the elevated part of the joint between the brick and the brick with a grinding head.
(2) Dotting: Use brick surface ash (brick medicine) to fill the incomplete part of the brick and the trachoma on the brick.
(3) Moisten the water: Use a moistened head to moisten the spotted area and the moistened place to flatten, and then moisten the entire wall surface with water to get the same color and texture.
(4) Flushing water: Sweep and rinse the entire wall with water and soft-bristled brushes, showing "real bricks and solid seams". Flushing should be arranged after the wall is completely completed and before the scaffolding is removed to avoid soiling the wall due to construction.
