First, the hollow floor tiles (a) phenomenon marble, granite, tile and other wall tiles after laying, with a small hammer percussion sound empty drums, people walk around some loose bricks. (b) Cause 1. The grassroots dries up, the watering wets not enough, causes the cement mortar to lose the water quickly, the bond strength of the brick and the mortar reduces; The cement mortar or the adhesive paving or the brushing takes too long, the mud air-drys, cannot have the adhesive effect. 2. The mortar did not add much, and the bonding layer did not work. 3. The grass-roots treatment is not clean or the prefabricated bricks are not soaked in wet or un-removed bricks on the back of the bricks before construction. The dried bricks quickly absorb the moisture in the cement mortar, resulting in dehydration of the mortar and affecting the setting hardening. 4. During construction, mortar is not full to form an empty drum, or the mortar is too thick, and the operation is heavy, causing the mortar to sink, the water to float, and the adhesiveness of the mortar to weaken.
5. After the mortar solidified, the brick removal was corrected. (III) Measures 1. Treat the grass-roots level as required, and do not collect water when watering the wet ground. 2. When using cement mortar, cement mortar is best dry mortar. Using 425# cement, the ratio of cement to sand is 1:2 to 4. 3. The tile is soaked in water before laying to remove surface floating soil. 4. Strictly follow the construction specifications.
Second, the veneer panel joints uneven, uneven gap (a) phenomenon Marble, granite, tile and other decorative stone tiles laying, the adjacent plate uneven, uneven width. (b) Cause 1. Strict purchase and selection of plates, plate thickness, size error, warping, skew and other defects. 2. There was no attention to leveling and lengthening the cable when paving. 3. The cement mortar or glue is pressed during the coagulation process to loosen the binding layer of the cement mortar or the adhesive and the facing brick. (III) Measures 1. The purchase and selection of plates must be strict and reject unqualified. 2. According to the provisions of the construction, at any time with the level and ruler leveling, the gap to lengthen the cable. 3. Do not tread before condensation.
Third, there is a sound of walking on the wooden floor (a) phenomenon to walk on the wood floor, wooden floor sound. (b) Cause 1. Wooden keel or wool floor is not firmly installed. 2. Wooden keels or wood floors have low moisture content, shrink after drying and cause loosening. 3. The wood floor is not firmly installed. (III) Measures 1. Strictly control the quality of wood, especially the moisture content, and prevent it from being soaked in water after entering the site. 2. Wooden keels are firmly installed according to regulations. 3. Wooden floor nails stick firmly. After nailing and sticking inspection at any time and place, does not meet the requirements of timely repairs.
Fourth, the wooden floor surface is not smooth, local warping drum (a) phenomenon The surface of the wooden floor is not flat, local drum or partial tilt. (b) Cause 1. Wood is deformed by moisture. 2. There is no moisture-proof layer on the wet ground, and wood floors are directly laid, and the wooden floor is damp. 3. During the construction, the depth of the projectile is not allowed. When the plane is leveled, the mast is not straight. 4. The wood floor is not firmly installed. 5. When the floor leveling day, shaved uneven. (III) Measures 1. Prevent wood from getting damp. 2. Wet floors were covered with high wood flooring and a moisture barrier must be provided. 3. Correct the horizontal line before laying the floor and surface floor, and adjust the error in time. 4. Wooden floor nails stick firmly. 5. Correctly operate the electric planer and master the manual net surface technology.
5. After the mortar solidified, the brick removal was corrected. (III) Measures 1. Treat the grass-roots level as required, and do not collect water when watering the wet ground. 2. When using cement mortar, cement mortar is best dry mortar. Using 425# cement, the ratio of cement to sand is 1:2 to 4. 3.
