During the construction of light insulating brick, the following key points should be paid attention to to to ensure the construction quality, waterproof performance and service life:

I. Construction preparation

Cleaning of the construction site: ensure that the construction site is clean and tidy, and there are no sundries.

Material inspection: Check whether the specifications, dimensions and flatness of insulating brick meet the requirements.

Tool preparation: prepare construction tools, such as mixers, plastering knives, mixing barrels, etc.

Ambient temperature: ensure that the construction environment temperature is moderate, not too high or too low.

II. Grass-roots treatment

Cleaning the base: ensure that the base is flat and dry, and free of impurities such as oil stain and dust. If there is unevenness, it needs to be smoothed or filled.

Waterproof layer protection: The waterproof layer shall not be damaged when cleaning the grass roots.

III. Mortar preparation

Proportion of cement mortar: ordinary cement mortar is prepared according to the cement: sand ratio of 1: 3 ~ 4 (mass ratio).

Special bonding mortar: If special bonding mortar is used, it should be prepared according to the product manual.

IV. Paving in insulating brick

Dry paving method or paste method: dry paving method (paving with dry mixed cement mortar) or paste method (using special adhesive) can be used.

Paving requirements:

Laying block by block in order to avoid unevenness.

Brick joint width is generally 8-10 mm..

When the shop is stuck, it shall not be struck by hard objects, and a rubber hammer shall be used to ensure smooth surface and smooth drainage.

Drainage design: During roof construction, drainage ditch should be reserved to ensure smooth drainage.

V. Brick joint treatment

Joint filling material: use special joint filling agent or polymer waterproof joint filling agent for joint filling.

Joint filling process:

First, remove the sundries in the joint, and fill the heat preservation caulking strip, leaving the surface 20mm deep.

When caulking with caulking material, it is necessary to compact and polish to ensure waterproof effect.

After joint filling is completed, clean the brick surface in time to avoid pollution.

VI. Frame joint treatment

Setting of frame joints: the vertical and horizontal spacing of frame joints should be no more than 6m.

Treatment method: the lower part of the frame joint is filled with heat preservation caulking strip, and the surface is left 20mm deep with flexible sealing material.

VII. Waterproof treatment

Waterproof layer protection: it is necessary to protect the waterproof layer during construction and avoid mixing mortar directly on the waterproof layer.

Blind drainage ditch: A through blind drainage ditch is set at the parapet gutter.

VIII. Maintenance

Watering maintenance: Watering maintenance shall be carried out within 12 hours after the completion of construction, and the maintenance time shall be at least 3 days.

Surface cleaning: ensure that the surface is clean and dry after the construction is completed.

IX. Other considerations

Material stacking: insulating brick should be neatly stacked to avoid excessive stacking and damage.

Rainy day construction: rainy day construction needs to take protective measures to avoid rain affecting construction quality.

High-rise building construction: For high-rise buildings, use theodolite to lay vertical control line to ensure uniform brick joints.

By strictly following the above construction precautions, the construction quality of lightweight insulating brick can be effectively improved, and its heat insulation, waterproof
