Stone Hardcover Engineering Construction Standards

Stone hardcover engineering construction standards

1. The variety, specification, color and performance of the plates used for the stone surface layer should meet the design requirements.

2. The surface layer and the next layer should be firmly combined without hollowing.

3. The quantity, specification, position, connection method and anti-corrosion treatment of the embedded parts and connecting parts of the veneer installation project must meet the design requirements.

4. The surface of the stone surface should be clean, smooth, and free of wear marks, and should have clear patterns, consistent color, uniform joints, straight perimeters, correct inlays, and no cracks, corners, or corrugations on the plates.

5. Main control data:

    Surface flatness: 2mm

    Slit straight: 2mm

    Seam height: 0.5mm

    The mouth of the skirting line is straight: 2mm

    Plate gap width: 1mm

Stone External Corner Patchwork

1. The external corner of the stone material adopts a 45° joint angle. After the paving is completed, the joints can be filled, the rounded corners can be polished, and polished.

2. The stone skirting line is made of adhesive finished positive corner skirting line, and the visible surface is polished.

3. It is strictly forbidden to use 45° angles for bathtub countertop stones. The flat surface is pressed against the vertical surface. The countertop stones can float out of the bathtub skirting stone twice as thick as the stone material.

Indoor Ground Level

1. The indoor ground needs to draw an elevation index map, including the structural elevation, the thickness of the bonding layer and material layer, the elevation of the finished surface, and the direction of slope finding.

2. The hall floor is 10mm higher than the kitchen floor.

3. The hall floor is 20mm higher than the bathroom floor.

4. The floor of the living room should be 5~8mm higher than the floor of the entrance hall.

5. The ground level of the corridor, living room and bedroom is uniform.

Stair Treads

1. The stair steps are square and consistent, the lines are straight, the corners are complete, the height is uniform, the surface is solid, flat and wear-resistant, and the color is consistent.

2. Cement mortar surface stairs have straight lines, complete corners and uniform height.

3. The stone surface is stepped, the corners are polished and polished, no color difference, consistent height, and uniform surface width.

4. The joints of the stepping bricks on the surface of the floor tiles are aligned, and the paving is firm.

5. A baffle or a water retaining line should be installed on the side of the steps to prevent pollution on the side of the stairs.

6. The surface of the skirting line of the stairs is smooth, the thickness of the prominent wall is consistent, the lines are neat, and there is no color difference.

7. The skirting line can be laid in one piece, and the seams are smooth.

8. The skirting line can be consistent with the steps, and the ladder is arranged.

Gap Between Skirting Line and Ground

1. Use the skirting line with rubber dust-proof strip to solve the gap between the skirting line and the wooden floor and prevent dust accumulation in daily use.

2. It is recommended to use adhesive baseboards for the baseboards. When nails are used for fixing, the baseboards need to reserve grooves and nails in the grooves.

3. It adopts PVC surface skirting line, and the surface is protected by PU film.
