Masonry technology, handed down by the master.

What is a mason? Masonry construction is not as simple as sticking a tile on the wall. Empty drum, foaming, unevenness, breakage and shedding are all common headaches for owners. Here, the construction steps and bricklayer's construction technology standards are introduced in detail.

A, mason approach steps

After the completion of water and electricity, it is the stage of mason construction!

Second, the bricklayer's construction preparation

1, construction environment preparation

① Leveling

Q: Why do you want to train?

Answer: Leveling is to level an uneven plane, so that the process with high requirements for ground elevation will be easier.

② Under what circumstances should leveling be done?

The flatness of the floor wood floor is relatively high. If laid directly on the uneven ground, the floor is prone to abnormal sound, and the probability of hollowing, cracking and warping will also increase. Not to mention the impact on the foot feel, the service life of the board is also greatly reduced.

Tiles, self-leveling cement floors, there is no need to level, they are a leveling process.

Remarks: Before construction, it is necessary to confirm whether the water and electricity layout is reasonable, and it will be more troublesome to change the rework problem.

2. Preparation of building materials

The materials needed in the construction process are: wall bricks, floor tiles, waist lines, antique bricks and other main materials, as well as auxiliary materials such as cement, sand and red bricks. Before construction, the materials on the construction site shall be inspected.

(1) First, check whether the varieties, specifications and colors of the main materials and Kangkang tiles meet the design requirements. Whether there is any damage.

According to the national standard, the shelf life of cement is about months. If the cement cakes, the bond strength will decrease. If caking occurs, cement should be replaced.

3. Preparation of construction tools

The tools used in the construction mainly include: hanging thread, guiding rule, cutting machine, shovel, ash bucket, brush, hammer, masonry knife, etc.

Third, the Mei Sen process.

1, demolition (mode re-planning)

Many owners are not satisfied with the original pattern and will redesign the layout, so tearing down the wall is a step. The bricklayer enters the site before the hydropower construction.

Remarks: Dismantle the wall carefully, follow the advice of the construction master, and pay special attention to the bearing wall.

2. Construction (Precautions for New Wall)

(1) The light steel keel wall shall be soundproofed.

(2) Avoid overweight during construction and consider the bearing problem. Generally, new walls are light partitions, made of lighter materials.

(3) Building a wall with large volume and weight requires the approval of the original design department and the property.

(4) Before plastering the outside of the new wall, barbed wire should be hung, so as to increase the stability of the wall and the external ceramic tile, and avoid the cracking of the new lightweight wall and the peeling of the plastering layer.

3, the kitchen and bathroom waterproof

Basic treatment → Stick the outline of the facade with masking paper → Brush the emulsion for the second time after drying → Brush the emulsion for the third time after drying → Close the water test.

Secretly tell you, waterproof for three times, it is difficult to leak;

4, toilet backfill

Q: What? The construction slag (waste and decoration garbage) that you backfilled?

A: Slagging happened in the last ten years! Poor hardness, easy to collapse, absorbent residue, stagnant water still stinks! ! !

Remarks: At present, Li Tao, backfill bag or overhead backfill are mostly used. No matter what kind of backfill is used, the waterproof layer should be done first to avoid unnecessary trouble in the later stage!

5. Gaiwa

① process flow

Grassroots treatment? Elastic thread? Paving the road (soaking bricks-drying bricks-starting work)? Tickle? clear

Basic treatment: clean the surface layer and solve the defects such as hollowing, cracking and sanding in advance.

Elastic line: the elevation control line will pop up around the wall, and the reticle will pop up on the ground to control the separation size of the floor tiles.

Paving: the back of the floor tile is wet and the front is dry. Put the floor tile on the cement mortar and tap it with a hammer, and it will be dense and flat.

Remarks: 1: 3 hard cement mortar is used, and the mortar thickness is about 25 mm.

Jointing: clean the floor tiles 24 hours after laying, the thin paste should be more than ≥48h hours, and it will take one month after punching. Before jointing, the impurities in the cracks in the floor tiles should be cleaned up, and jointing should be carried out with special caulking agent.

Cleaning: walk and wipe after 24 hours of completion.

② Precautions for laying ceramic tiles:

Many owners like to put tiles on the walls. It should be noted that the tiles on the wall can't be stuck with water and sediment, which is easy to fall off. Stick it firmly with tile glue.

The tiles in the kitchen and bathroom should have a slope of running water. If the original waterproof layer is damaged during construction, waterproof treatment should be done, and the accumulated water should be tested for 12 hours to see if there is leakage.

12h is completed, knock on the brick surface for inspection, and there is no empty drum sound.

6. Others: pipeline painting, installation of squatting pan in balcony bathroom, floor drain, etc.

Four. accept

1, shape

(1) The color and model of the brick are unified without chromatic aberration. Founder has no damage, no stains, no sand and no honeycomb;

(2) the gap is consistent, the joint height is less than or equal to ≤0.5mm, and the brick joint size error is less than or equal to1mm;

(3) Each wall should not have two columns of non-whole bricks, and should not be less than1/3 of the whole brick;

Step 2 empty drum

The main channel of bricklaying hollowing shall not be hollowed out, the hollowing area of single brick in other areas shall be ≤ 15%, and the number of hollowed bricks shall be ≤ 5% of the total number;

3. Kitchen and bathroom

(1) The kitchen floor is 5~ 10mm lower than other floors to ensure no leakage.

(2) The floodwater gradient of the toilet, when testing the water on the ground, the water should be collected and drained by the floor drain, and there should be no obvious water accumulation on the tile floor.

(3) When the floor tile is laid, the floor drain shall be laid with the "back" technology.

4, wall and floor tile level off

(1) Use 2m guiding rule to check the surface smoothness, the allowable deviation is ≤5mm, and the inlay should be firm.

(2) The surface of the installation place of the finished product is smooth, within the detection range of 2m guiding rule, less than or equal to ≤3mm.

5, the height of the threshold

The threshold of wet area should be slightly higher than the wet ground by more than 5 mm
