Description

Technical Field

[0001] This utility model belongs to the field of building decoration and renovation technology, specifically to a rock slab floor paving structure. Background Technology

[0002] Efflorescence on stone is a common stone disease. Because stone has a large number of capillaries, it is easily polluted by the environment and human factors. For example, efflorescence on the original concrete base layer can penetrate into the stone matrix, causing stone diseases such as water stains, efflorescence, rust stains, and oil stains. This not only affects the appearance of the stone, but also seriously affects its service life. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a slab flooring paving structure. This application provides the following technical solution:

[0004] The system includes, from bottom to top, a ground base layer, a lightweight sound-insulating mortar leveling layer, a rock slab bonding layer, and a rock slab. The bottom surface of the rock slab is provided with a back mesh layer, which includes lightweight back mesh mortar and mesh cloth. The mesh cloth is bonded to the bottom surface of the rock slab by the lightweight back mesh mortar.

[0005] A first interface treatment layer is provided between the ground base layer and the lightweight sound-insulating mortar leveling layer.

[0006] A second interface treatment layer is provided between the lightweight sound-insulating mortar leveling layer and the rock slab bonding layer.

[0007] Several reinforcing bars are fixed on the ground base layer. The reinforcing bars are spaced apart and their top surfaces are flush. The lightweight sound-insulating mortar leveling layer is located between the reinforcing bars.

[0008] The reinforcing bars are made of lightweight sound-insulating mortar that has been cured.

[0009] Both the first interface treatment layer and the second interface treatment layer are formed by spreading lightweight interface mortar.

[0010] The slab bonding layer is formed by spreading lightweight bonding mortar.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] Applying a back mesh treatment to the bottom surface of the rock slab, combined with effective isolation by lightweight interface mortar and leveling by lightweight sound-insulating leveling mortar, can effectively prevent efflorescence caused by efflorescence of the concrete base layer.

[0022] Please refer to Figure 1-3 As shown, this utility model provides a slab flooring structure, which includes a ground base layer 1, a lightweight sound-insulating mortar leveling layer 2, a slab bonding layer 3, and a slab 4 arranged sequentially from bottom to top. A back mesh layer 41 is provided on the bottom surface of the slab 4. The back mesh layer 41 includes lightweight back mesh mortar and alkali-resistant glass fiber mesh cloth. The alkali-resistant glass fiber mesh cloth is bonded to the bottom surface of the slab 4 by the lightweight back mesh mortar.

[0023] A first interface treatment layer 5 is provided between the ground base layer 1 and the lightweight sound insulation mortar leveling layer 2.

[0024] A second interface treatment layer 6 is provided between the lightweight sound-insulating mortar leveling layer 2 and the rock slab bonding layer 3.

[0025] Several reinforcing bars 11 are fixed on the ground base layer 1. The reinforcing bars 11 are spaced apart and their top surfaces are flush. The lightweight sound-insulating mortar leveling layer 2 is located between the reinforcing bars 11.

[0026] Rib 11 is made of lightweight sound-insulating mortar that has been cured.

[0027] Both the first interface treatment layer 5 and the second interface treatment layer 6 are formed by spreading lightweight interface mortar.

[0028] The slab bonding layer 3 is formed by laying lightweight bonding mortar.

[0029] The lightweight interface mortar uses Stof lightweight interface mortar, composed of silicate cement, modified vitrified microspheres, and redispersible latex powder, etc., and is mechanically mixed with a water-cement ratio of approximately 0.90:1; the lightweight sound insulation leveling mortar uses Stof lightweight sound insulation mortar, composed of silicate cement, modified vitrified microspheres, sand, and redispersible latex powder, etc., and is mechanically mixed with a water-cement ratio of approximately 0.33:1; the lightweight bonding mortar uses Stof lightweight bonding mortar, composed of silicate cement, modified vitrified microspheres, and redispersible latex powder, etc., and is mechanically mixed with a water-cement ratio of approximately 0.42:1; the lightweight back mesh mortar uses Stof lightweight back mesh mortar, composed of silicate cement, modified vitrified microspheres, and redispersible latex powder, etc., and is mechanically mixed with a water-cement ratio of approximately 0.50:1.

[0030] In specific implementation, the process is as follows: 1. Base treatment: Clean the dirt and dust from the base layer 1, fill construction holes, etc., and then use a floor planer to remove any attached materials from the base layer 1. Any protrusions ≥6mm should be leveled. 2. Marking lines and dividing the base layer 1 into several rectangular grids with a width ≤1.5m. 3. Bottom surface reinforcement: Use lightweight sound-insulating mortar to build reinforcements of the same thickness on the marked lines, and use a level to ensure that the top surfaces are at the same horizontal level. After the lightweight sound-insulating mortar cures, it forms reinforcement strips 2. 4. Wetting the ground: Wet the base layer... 5. Sprinkle water on the ground surface to moisten it, making it softer, reducing concrete shrinkage, and increasing the adhesion of the lightweight sound-insulating leveling mortar; 6. Soak the lightweight interface mortar and lightweight sound-insulating leveling mortar in water for half an hour before stirring them into a slurry; 7. Apply the lightweight interface mortar to the ground base layer 1 to form the first interface treatment layer 5; 8. Leveling construction: Pour the lightweight sound-insulating leveling mortar between the reinforcing bars 2 from the inside out, and smooth it with an aluminum alloy ruler. When smoothing, keep both ends of the aluminum alloy ruler in contact with the top surface of the reinforcing bars 2, and then smooth it with a large washboard; 9. Fine grinding. After the lightweight sound-insulating leveling mortar has cured to form lightweight sound-insulating mortar leveling layer 2, use a grinder to grind its surface to remove any protrusions or uneven parts. After grinding, remove dust and debris, and use lightweight sound-insulating leveling mortar to repair gaps and hollow areas; 9. Second elastic segmentation: According to the size of the rock slabs, use elastic lines on the lightweight sound-insulating leveling layer to determine the laying position of each rock slab; 10. Interface treatment: For each rock slab laid, use a roller to spread lightweight interface mortar into the corresponding segment of the rock slab to be laid, forming the second interface treatment layer 6; 11. Scraping 11. Apply adhesive: Apply lightweight adhesive mortar to the second interface treatment layer 6 and spread it evenly with a notched rake to a thickness of approximately 7mm; 12. Apply alkali-resistant fiberglass mesh backing mortar to the bottom of the slab 4 before laying it; 13. Lay the slab: Lay the slab 4 on the lightweight adhesive mortar and lay it smoothly using a slab lifter; 14. Vibrate and level: Use a vibrator to vibrate and level the slab from the center outwards; 15. Level and cure: Clean the slab and edges of dust and mortar with a cloth, then use a leveling tool to level it and allow it to cure.
