Description

Technical Field

[0001] This invention belongs to the field of building floor tile construction technology, specifically relating to a method for laying floor tiles throughout a house. Background Technology

[0002] In traditional tile laying methods, cement mortar is commonly used as a binding material. However, cement mortar has limitations in terms of early strength and durability, and its construction efficiency is relatively low, with significant deviations due to worker skill. Therefore, a new method is needed to improve the quality and efficiency of tile laying. Summary of the Invention

[0003] The purpose of this invention is to provide a whole-house floor tile laying method that solves the problems of poor quality and low efficiency in traditional floor tile laying.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A method for laying floor tiles throughout a house includes the following steps:

[0006] Step 1: Clean the base layer;

[0007] Step 2: Mix the blast furnace ore powder and sand evenly, and spread them evenly on the base layer to form a dry layer;

[0008] Step 3: Determine the placement of the floor tiles on the dry-lay layer;

[0009] Step 4: Clean the floor tiles and pre-wet the bonding surfaces of the tiles;

[0010] Step 5: Spray the alkali activator evenly onto the tile laying area, then place the tiles flat to ensure a tight bond between the tiles and the dry-laid layer.

[0011] Step 6: Clean the surface of the floor tiles.

[0012] Furthermore, in step 1, the cleaning of the base layer includes cleaning the surface, repairing damaged parts, and polishing to ensure that the base layer is flat, firm, and free of impurities.

[0013] Furthermore, in step 2, the mass ratio between blast furnace ore powder and sand is 1:(1.0~3.5).

[0014] Furthermore, in step 2, the dry-lay thickness is 10-40mm, and compaction is performed after dry-laying to ensure that the entire dry-lay thickness is completely uniform and without any depressions or protrusions.

[0015] Furthermore, in step 3, the laying position of the floor tiles is determined by laying out lines, and the edge lines of the floor tiles are marked on the dry-laid layer.

[0016] Furthermore, in step 5, the alkali activator is a mixture of water, water glass and sodium hydroxide, and the mass of Na2O in the alkali activator is greater than or equal to 6% of the mass of blast furnace ore powder.

[0017] Furthermore, in step 5, the mass ratio of water, water glass, and sodium hydroxide is (0.85-1.7):1:(0.2-0.3).

[0018] Furthermore, in step 5, the alkali activator is packaged in a single bottle according to the amount required for laying a single tile, and one bottle is sprayed onto each tile.

[0019] Furthermore, in step 6, tools are used to level the surface of the floor tiles and excess gel material is cleaned up in time to ensure that the surface of the floor tiles is clean and flat.

[0020] Furthermore, the floor tiles are ceramic tiles.

[0021] The beneficial effects of this invention are:

[0022] 1. The gel material used has high early strength, and the bottom layer of mineral powder and sand is laid out in a whole-house manner, and the activator is pre-made, which can greatly save the construction period.

[0023] 2. The mineral powder and sand used are laid out and compacted throughout the entire house, and the levelness is verified after compaction. Therefore, compared with individual tiling, the deviation caused by workers laying the mortar manually and mixing it manually is smaller.

[0024] 3. Due to the rapid bonding properties of the gel material, the tiled floor can be put into normal use quickly.

[0025] 4. The gel material used has higher long-term strength and a denser bond compared to cement mortar with the same water-cement ratio.

[0026] 5. Because the amount of gel material used for each tile has been precisely calculated and prepared, the resulting grout lines are relatively smaller, resulting in a more aesthetically pleasing installation.

[0027] 6. The entire process does not use cement, thus achieving the goal of energy conservation and emission reduction.

[0028] The aforementioned main solution of the present invention and its various further alternative solutions can be freely combined to form multiple solutions, all of which are solutions that can be adopted and are claimed by the present invention; furthermore, the (non-conflicting alternatives) can also be freely combined with each other and with other alternatives. Those skilled in the art, after understanding the solution of the present invention, will realize from the prior art and common general knowledge that there are many combinations, all of which are technical solutions to be protected by the present invention, and will not be exhaustively listed here. Attached Figure Description

[0029] Figure 1This is a schematic diagram of the structure of the present invention.

[0030] In the diagram: 1-base layer, 2-dry-laid layer, 3-floor tiles. Detailed Implementation

[0031] The following non-limiting examples are used to illustrate the present invention.

[0032] Example 1:

[0033] refer to Figure 1 As shown, a whole-house floor tile laying method is used, where the floor tile 3 is ceramic tile, and includes the following steps.

[0034] Step 1: Clean the base layer 1, including cleaning the surface, repairing damaged parts, and sanding, to ensure that the base layer 1 is flat, firm, and free of impurities.

[0035] Step 2: Select S95 mineral powder with a specific surface area ≥ 400 m². 2 / kg, the sand is medium sand, and it needs to be pre-wetted before use to make the sand surface dry, and its mud content must be ≤1%.

[0036] Blast furnace ore powder and sand are mixed evenly, with a mass ratio of 1:3 between the blast furnace ore powder and sand. The mixture is then evenly spread dry onto base layer 1 to form dry layer 2. The dry layer thickness is 20mm. After dry spreading, it is compacted to ensure that the entire dry layer thickness is completely uniform, without any depressions or protrusions. The height is then confirmed using instruments such as a laser meter to ensure there are no deviations.

[0037] Step 3: Determine the laying position of the floor tile 3 on the dry-laid layer 2. Determine the laying position of the floor tile 3 by laying out lines, and use tools to draw the edge line of the floor tile 3 on the dry-laid layer 2 to facilitate the alignment of the floor tile 3 during laying.

[0038] Step 4: Clean floor tile 3 and pre-wet the bonding surface of floor tile 3.

[0039] Step 5: The alkali activator is a mixture of water, water glass and sodium hydroxide. The mass ratio of water, water glass and sodium hydroxide is 1.65:1:0.25. Based on the material required for laying a single 3-piece floor tile, the mass of Na2O in the alkali activator is equal to 6% of the mass of blast furnace ore powder.

[0040] The alkali activator is evenly sprayed onto the laying position of tile 3, and then tile 3 is placed flat to ensure a tight bond between tile 3 and dry layer 2. The alkali activator is packaged in a single bottle according to the amount required for laying a single tile 3, and one bottle is sprayed for each tile 3.

[0041] Step 6: Clean the surface of floor tile 3, use tools to level the surface of floor tile 3, and clean off any excess gel material in time to ensure that the surface of floor tile 3 is clean and flat.

[0042] For example, if a single floor tile is 60cm x 60cm in length and width, and its dry-lay thickness is 2cm, then the volume of mineral powder and sand required to lay that single tile is 60 x 60 x 2 = 7200cm³. 3 =0.0072m 3 The mass ratio of mineral powder to sand is 1:3, and the densities of mineral powder and sand are respectively 2900 kg / m³. 3 and 2600kg / m 3 Calculations show that the volume ratio of mineral powder to sand is 3:10, therefore the volume of mineral powder in a single ceramic tile is 0.0072 × 3 / 13 = 0.00166 m³. 3 The mass of the tile is calculated to be 4.82 kg. Similarly, the mass of sand required for a single tile is 14.4 kg.

[0043] The Na₂O mass in the alkali activator is 4.82 × 6% = 0.29 kg. Sodium hydroxide is used to adjust the modulus of the water glass to 1.0; the specific amount needs to be calculated based on the Na₂O content of the water glass used. Here, a simplified calculation is based on a water glass:sodium hydroxide ratio of 4:1 (mass ratio). Adjustments are made according to the water and Na₂O content in the water glass, resulting in a water:water glass:sodium hydroxide ratio of 1.65:1:0.25 (mass ratio). Therefore, the specific composition of a single bottle of alkali activator prepared for a single brick is 4 kg of water, 2.4 kg of water glass, and 0.6 kg of sodium hydroxide.

[0044] Based on the amount of alkali activator required for a single tile, the alkali activator should be bottled individually. If the plastic bottle is large or the individual tile area is small, the water, water glass, and sodium hydroxide should be mixed in advance. If the plastic bottle is small, only the water glass and sodium hydroxide should be mixed and bottled. Water should be added and stirred evenly before use.

[0045] After 30 minutes of construction using this method, the strength is ≥3MPa, the hollow rate is 0, the flatness error of the floor tiles is less than ±0.2%, and the maximum value is less than 2mm.

[0046] Example 2:

[0047] refer to Figure 1 As shown, a whole-house floor tile laying method differs from Example 1 in that: in step 2, the mass ratio between blast furnace ore powder and sand is 1:2.5, and the dry laying thickness is 40mm; in step 5, the mass ratio of water, water glass and sodium hydroxide is 3.4:4:1, and the mass of Na2O in the alkali activator is equal to 9% of the mass of blast furnace ore powder.

[0048] The strength is ≥5MPa after 30 minutes of construction using this method.

[0049] Example 3:

[0050] refer to Figure 1As shown, a whole-house floor tile laying method differs from Example 1 in that: in step 2, the mass ratio between blast furnace ore powder and sand is 1:1, and the dry laying thickness is 10mm; in step 5, the mass ratio of water, water glass and sodium hydroxide is 3.4:4:1, and the mass of Na2O in the alkali activator is equal to 9% of the mass of blast furnace ore powder.

[0051] The strength is ≥8MPa after 30 minutes of construction using this method.

[0052] The foregoing basic examples and their further alternative examples of the present invention can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed by the present invention. In the present invention, each alternative example can be arbitrarily combined with any other basic example and alternative example.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
