Before the construction of the Chongqing floor , the horizontal control line is popped up around the 1000mm position on the plastered layer on the wall. According to the one-meter control line of the indoor building, the design thickness of the overall surface layer is combined to determine a set of apartment floor control from one meter. Uniform height down the line, and check whether the thickness of the insulation layer is within the range allowed by the specification. A laser level is used to rake the thickness of the gray cake. At the same time as raking, the net height of the floor between the rake and the ceiling should be fully checked. If the structural elevation deviation cannot be remedied by the thermal insulation thickness, the floor or ceiling should be polished or beaten according to the elevation control line.

In view of the household clearance inspection point, the floor net height detection point is arranged at a corner of the wall about 500mm from both the length and width of the wall. Therefore, a harrowing point should be added at this position, and the floor net height value between the harrow and the ceiling should be checked. The rake points in other positions should be set according to the vertical and horizontal spacing not more than 2000mm and the oblique spacing not more than 2500mm.

In order to ensure the accurate elevation of the indoor floor and indoor window slab floor where there is a difference in height, a fine stone burr should be set according to the elevation control line before pouring the floor. As a baffle when pouring the floor with a height difference position, when the floor is being poured, it is necessary to temporarily block the height difference position floor using wood and other materials, causing the position of the edge to be shifted, inaccurate, or the edge is too rough On the other hand, the top mouth of the flanging is determined by the control line, which is directly used as the bar in the floor pouring process, which effectively prevents the size deviation of this special position from being too large.

After the floor is poured, make sure that the pitch of the floor surface is uniform and the lines are straight. You should use a fixed-size mold to engrav on the ruler. After finishing the surface, use an engraver to perform the engraving. , While maintaining a 200mm wide light receiving surface without engraving. Leave a 100mm width around the bottom of the bottom of the wall around the room without engraving.

After the floor is finally set, the floor should be cut immediately when the strength is not less than 1.2MPA. The joints should be set at the position where the plane change is likely to cause stress concentration. Separate grid joints should be set at the aisles and adjacent door leaves, and the beam and wall support positions should also be set at the large room. In order to maintain the uniform and beautiful appearance of the cut seams of each apartment, the plan layout of the partitioned seams of each apartment should be determined in advance according to the plan of the apartment. The slit should be stretched before cutting, and effective measures such as ruler should be used to ensure that the slit is straight and beautiful.
