Description

Technical Field

[0001] The present invention relates to the field of construction, and particularly to a paving structure and a paving method for interior ceramic tiles in buildings. Background Art

[0002] The traditional construction process for paving tiles has no standard procedures and no standard auxiliary materials. During the construction process, no tools are used for positioning. Instead, construction is directly carried out between tiles or positioning is relied on the woven bags on the tile packaging, and then flattening is performed by the feel of the workers. The material is neat cement slurry, and the paving method is semi-dry and semi-wet construction, and there is no standard for the ratio of cement to sand. The method of using cement mortar to paste tiles has been used for many years and is technically mature, but it has some deficiencies: First, it highly tests the experience and skills of the tile installers. If the cement is not evenly applied, air pockets will be generated on the back of the tiles. The presence of air pockets indicates that the area where the cement adheres to the tiles is small, and the tiles are likely to fall off. Also, the ratio of cement and sand needs to be adjusted by the master himself. If the ratio is adjusted wrongly, the tiles cannot be firmly adhered. Therefore, in the traditional process, it is too dependent on the individual construction level and state of the master and cannot be replicated.

[0003] After the tiles are paved, they will expand and contract due to changes in natural conditions. There are mainly three aspects that cause thermal expansion and contraction. One is the leveling layer and the semi-dry and semi-wet mortar layer under the tiles, the second is the bonding layer, and the third is the tiles. The tiles have the smallest shrinkage because they have been fired at high temperatures and there is no need to worry about deformation of the tiles themselves. Secondly, it is the leveling layer and the semi-dry and semi-wet mortar layer, in which the proportion of sand is 70% - 75%. The higher the proportion, the lower the shrinkage rate. The bonding layer has the largest shrinkage, especially the traditional paving uses neat cement slurry, and the shrinkage ratio is large. Therefore, the tiles will bulge or the edges will break due to thermal expansion and contraction after paving. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies existing in the prior art and provide a paving structure and a paving method for interior ceramic tiles in buildings.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: A paving structure for interior ceramic tiles in buildings, the paving structure for interior ceramic tiles in buildings successively includes a first cement layer, a buffer layer, a second cement layer, a bonding agent layer, and a tile layer from bottom to top;

[0006] The buffer layer is provided with a plurality of vertical rubber columns, the plurality of vertical rubber columns are spaced apart, and the voids between the plurality of vertical rubber columns in the buffer layer are filled with a filler, and the filler is made of a mixture of foam particles, cement, sand, and water.

[0007] The above-mentioned structure for laying interior ceramic tiles in buildings sets several vertical rubber columns and fillers between the first cement layer and the second cement layer as a buffer layer. When thermal expansion and contraction occur, the buffer layer can play a certain buffering role through its own elastic deformation to consume stress, preventing the tiles from warping or deforming. Thus, it can effectively avoid the deformation caused by the thermal expansion and contraction of the tile floor laying structure, so as to achieve the close-seam laying of tiles. The above-mentioned structure for laying interior ceramic tiles in buildings sets an adhesive layer to replace the traditional cement layer to fix the tiles. At the same time, the adhesive layer also has good viscoelasticity. When the tiles undergo thermal expansion and contraction, the adhesive layer can play a certain buffering role through its own elastic deformation to consume stress, preventing the tiles from warping or deforming. The above-mentioned structure for laying interior ceramic tiles in buildings sets several vertical rubber columns and fillers between the first cement layer and the second cement layer as a buffer layer, and the filler is made of a mixture of foam particles, cement, sand and water, which not only ensures the strength of the buffer layer but also improves the elasticity of the buffer layer, and can effectively avoid the deformation caused by the thermal expansion and contraction of the tile floor laying structure, so as to achieve the near-seamless laying of tiles.

[0008] Preferably, the rubber column extends upward to the adhesive layer, and the rubber column extends downward into the first cement layer.

[0009] The above-mentioned structure for laying interior ceramic tiles in buildings extends the rubber column upward to the adhesive layer and extends the rubber column downward into the first cement layer, which realizes better fixation of the rubber column, enables the rubber column to directly support the ground and the tiles, improves the buffering effect, and can effectively avoid the deformation caused by the thermal expansion and contraction of the tile floor laying structure.

[0010] Preferably, grooves are provided on the filler on the upper surface of the buffer layer, and convex ribs matching the grooves are provided on the bottom surface of the second cement layer. The convex ribs and the grooves are mutually engaged to fix the second cement layer and the buffer layer.

[0011] The above-mentioned structure for laying interior ceramic tiles in buildings sets grooves on the filler, making the combination of the second cement layer and the buffer layer firmer, and avoiding the upwelling of cement slurry at the joints of adjacent tiles during the laying process. After forming the buffer layer, by cutting grooves in the buffer layer and then laying the cement slurry above the buffer layer, convex ribs matching the grooves will be formed on the bottom surface of the second cement layer.

[0012] Preferably, the tile layer comprises a plurality of tiles, the grooves comprise a plurality of first grooves and a plurality of second grooves, one first groove is correspondingly arranged under each tile, the first grooves form a ring with the head and the tail connected, the geometric figure formed by each ring-shaped first groove and the side of the corresponding tile is geometrically similar, each ring-shaped first groove is smaller than the geometric figure formed by the side of the corresponding tile, and the center of the ring-shaped first groove and the center of the corresponding tile are located on the same vertical axis.

[0013] By correspondingly arranging one first groove under each tile in the above building interior ceramic tile paving structure, the bonding strength at the joint of adjacent tiles can be effectively guaranteed.

[0014] Preferably, the second grooves are a plurality of longitudinally and transversely intersecting grooves, and the second grooves penetrate through the first grooves.

[0015] By correspondingly arranging second grooves under each tile in the above building interior ceramic tile paving structure, the bonding strength at the joint of adjacent tiles can be effectively guaranteed.

[0016] Preferably, the rubber columns are distributed at intervals in a matrix, the distance between the rubber columns is 8 - 12 cm, and the radius of the rubber columns is 4 - 8 mm.

[0017] The distance between the rubber columns in the buffer layer of the above building interior ceramic tile paving structure is 8 - 12 cm, and the radius of the rubber columns is 4 - 8 mm, which is beneficial to better improving the elasticity of the buffer layer.

[0018] Preferably, the thickness of the adhesive layer is 2 - 3 mm, the gap between each adjacent tile is not more than 0.5 mm, and the distance between the tile layer and the wall surface is 5 - 10 cm.

[0019] The gap between adjacent tiles in the above building interior ceramic tile paving structure is not more than 0.5 mm, which is close to seamless paving. Moreover, the distance between the tile layer and the wall surface is 5 - 10 cm. By reserving a gap of 5 - 10 cm between the tile layer and the wall surface, sufficient expansion and heat dissipation space can be formed, thereby further avoiding arching and falling off of the tiles and ensuring the stability of the seamless paving of the tiles.

[0020] Preferably, the adhesive layer comprises cellulose ether and tile adhesive.

[0021] The present invention also provides a paving method for a building interior ceramic tile paving structure, and the method comprises the following steps:

[0022] (1) Detect and position the ground;

[0023] (2) Mix cement and water evenly to obtain cement slurry, and evenly sprinkle the cement slurry onto the ground to form a first cement layer;

[0024] (3) Mix foam particles, cement, sand and water to obtain cement mortar, evenly lay the cement mortar above the first cement layer to form the filler of the buffer layer, and vertically insert a number of rubber columns into the filler of the buffer layer. The filler and a number of vertical rubber columns form the buffer layer;

[0025] (4) Mix cement and water evenly to obtain cement slurry, and evenly sprinkle the cement slurry onto the buffer layer to form a second cement layer;

[0026] (5) Apply an adhesive on the back of the ceramic tile and seal and lay it above the second cement layer to form an adhesive layer and a ceramic tile layer.

[0027] The above method is simple to operate. The indoor ceramic tile paving structure obtained by paving can play a certain buffering role through its own elastic deformation to consume stress, prevent the ceramic tile from warping or deforming, and the above method has a weak dependence on the operation level of technicians.

[0028] Preferably, after the step (3) is completed, annular first grooves that are connected end to end are cut on the upper surface of the buffer layer according to the shape and size of the ceramic tile. The geometric figures formed by the respective annular first grooves and the sides of the ceramic tile are geometrically similar, and the geometric figures formed by the respective annular first grooves are smaller than the geometric figures formed by the sides of the ceramic tile.

[0034] To better illustrate the purpose, technical solution and advantages of the present invention, the present invention will be further described below in conjunction with specific embodiments.

[0035] Embodiment 1

[0036] As a building interior ceramic tile laying structure according to an embodiment of the present invention, as shown in Figure 1 、 Figure 2 and Figure 3 , the building interior ceramic tile laying structure sequentially includes a first cement layer 11, a buffer layer 12, a second cement layer 13, an adhesive layer 14 and a ceramic tile layer 15 from bottom to top;

[0037] The buffer layer 12 is provided with a plurality of vertical rubber columns 122, the plurality of vertical rubber columns 122 are spaced apart, and the voids between the plurality of vertical rubber columns 122 in the buffer layer 12 are filled with a filler 126.

[0038] The building interior ceramic tile laying structure of this embodiment sets a plurality of vertical rubber columns and fillers between the first cement layer and the second cement layer as a buffer layer. When thermal expansion and contraction occur, the buffer layer can play a certain buffering role through its own elastic deformation to consume stress, preventing the ceramic tiles from warping or deforming, so as to effectively avoid the deformation caused by the thermal expansion and contraction of the ceramic tile floor laying structure, so as to achieve the tight joint laying of the ceramic tiles. The above-mentioned building interior ceramic tile laying structure is provided with an adhesive layer to replace the traditional cement layer to fix the ceramic tiles. At the same time, the adhesive layer also has good viscoelasticity. When the ceramic tiles undergo thermal expansion and contraction, the adhesive layer can play a certain buffering role through its own elastic deformation to consume stress, preventing the ceramic tiles from warping or deforming.

[0039] Furthermore, the filler 126 is made by mixing foam particles 121, cement, sand and water. The ceramic tile paving structure indoors ensures the strength of the buffer layer and improves its elasticity by arranging a number of vertical rubber columns and fillers between the first cement layer and the second cement layer as a buffer layer, and the filler is made by mixing foam particles, cement, sand and water, which can effectively avoid deformation caused by the thermal expansion and contraction of the ceramic tile floor paving structure, so as to achieve nearly seamless paving of the ceramic tiles.

[0040] Furthermore, the rubber column 122 extends upward to the adhesive layer 14, and the rubber column 122 extends downward into the first cement layer 11. The ceramic tile paving structure indoors extends the rubber column upward to the adhesive layer and downward into the first cement layer, which realizes better fixation of the rubber column, enables the rubber column to directly support the floor and the ceramic tiles, improves the buffering effect, and can effectively avoid deformation caused by the thermal expansion and contraction of the ceramic tile floor paving structure.

[0041] Furthermore, grooves 123 are arranged on the filler on the upper surface of the buffer layer 12, and convex ribs matching the grooves 123 are arranged on the bottom surface of the second cement layer 13. The convex ribs and the grooves 123 are mutually engaged to fix the second cement layer 13 and the buffer layer 12. The ceramic tile paving structure indoors makes the second cement layer and the buffer layer combine more firmly by arranging grooves on the filler, and avoids the upwelling of cement slurry at the joints of adjacent ceramic tiles during the paving process. After forming the buffer layer, grooves are cut on the buffer layer, and then cement slurry is laid above the buffer layer, and convex ribs matching the grooves will be formed on the bottom surface of the second cement layer.

[0042] Furthermore, the ceramic tile layer 15 includes a number of ceramic tiles. The grooves 123 include a number of first grooves 124 and a number of second grooves 125. One first groove 124 is correspondingly arranged under each ceramic tile. The first grooves 124 are in a head-to-tail connected ring shape. The geometric figures formed by the ring-shaped first grooves 124 and the corresponding sides of the ceramic tiles are geometrically similar. The ring-shaped first grooves 124 are smaller than the geometric figures formed by the corresponding sides of the ceramic tiles. The centers of the ring-shaped first grooves 124 and the centers of the corresponding ceramic tiles are located on the same vertical axis. The ceramic tile paving structure indoors can effectively ensure the bonding strength at the joints of adjacent ceramic tiles by correspondingly arranging a first groove under each ceramic tile.

[0043] Furthermore, the second grooves 125 are a number of criss-crossing grooves, and the second grooves 125 penetrate the first grooves 124. The ceramic tile paving structure indoors can effectively ensure the bonding strength at the joints of adjacent ceramic tiles by correspondingly arranging second grooves under each ceramic tile.

[0044] Furthermore, the rubber columns 122 are distributed at intervals in a matrix pattern, the spacing between the rubber columns 122 is 8 - 12 cm, and the radius of the rubber columns 122 is 4 - 8 mm. A spacing of 8 - 12 cm between the rubber columns of the buffer layer of the building interior ceramic tile paving structure and a radius of 4 - 8 mm for the rubber columns are beneficial to better improve the elasticity of the buffer layer.

[0045] Furthermore, the thickness of the adhesive layer 14 is 2 - 3 mm, the gap between each adjacent tile is not more than 0.5 mm, and the distance between the tile layer 15 and the wall surface is 5 - 10 cm. The gap between adjacent tiles of the building interior ceramic tile paving structure is not more than 0.5 mm, approaching seamless paving, and the distance between the tile layer and the wall surface is 5 - 10 cm. By leaving a gap of 5 - 10 cm between the tile layer and the wall surface, sufficient expansion and heat dissipation space can be formed, thereby further avoiding tile arching and falling off and ensuring the stability of the tile close-seam paving.

[0046] Preferably, the adhesive layer 14 includes cellulose ether and tile adhesive.

[0047] Research results on the performance of the building interior ceramic tile paving structure of Example 1.

[0048] Detection method: Lay the building interior ceramic tile paving structure in the manner of Example 1. First, lay some tiles. When heating, randomly select the gap between two tiles, and use an S-shaped mechanical sensor and an infrared imaging temperature gun to measure the temperature and extrusion stress at the corresponding positions. The results are shown in Table 1.

[0049] Table 1

[0050]

[0051]

[0052] As can be seen from Table 1, when the tile temperature rises, the extrusion stress will also increase accordingly. However, when it is below 45 degrees, the stress change degree is relatively small, indicating that the building interior ceramic tile paving structure of Example 1 has a significant effect on reducing stress.

[0053] Example 2

[0054] As a paving method for a building interior ceramic tile paving structure according to an embodiment of the present invention, the method includes the following steps:

[0055] (1) Floor detection and positioning;

[0056] (2) Mix cement and water evenly to obtain cement slurry, and evenly pour the cement slurry onto the floor to form a first cement layer;

[0057] (3) Mix the foam particles, cement, sand and water to obtain cement mortar. Uniformly lay the cement mortar above the first cement layer to form the filler of the buffer layer. Vertically insert several rubber columns into the filler of the buffer layer. The filler and several vertical rubber columns form the buffer layer;

[0058] (4) Mix cement and water in proportion and mix them evenly to obtain cement slurry. Evenly sprinkle the cement slurry onto the buffer layer to form the second cement layer;

[0059] (5) Apply an adhesive on the back of the ceramic tile and seal and lay it above the second cement layer to form an adhesive layer and a ceramic tile layer.

[0060] The above method is simple to operate. The laid indoor ceramic tile paving structure of the building can play a certain buffering role through its own elastic deformation to consume stress, prevent the ceramic tile from warping or deforming, and the above method has a weak dependence on the operation level of technicians.

[0061] Preferably, after the step (3) is completed, annular first grooves that are connected end to end are cut on the upper surface of the buffer layer according to the shape and size of the ceramic tile. The geometric figures formed by the respective annular first grooves and the sides of the ceramic tile are geometrically similar, and each annular first groove is smaller than the geometric figure formed by the sides of the ceramic tile. A second groove is cut on the upper surface of the buffer layer. The second groove is a plurality of grooves that crisscross each other, and the second groove penetrates the first groove.

[0062] Specifically, in the step (1), detect whether there are any hollow parts on the ground, knock out the hollow parts, brush and seal the mud filling area, crack area and water seepage area of the ground with floor primer, clean the ground, draw the horizontal elevation line of the house, and draw the horizontal elevation line of the ceramic tile; Detect the ceramic tiles to be laid, eliminate defective products, conduct a grain matching trial laying on the qualified ceramic tiles, and find the most suitable laying combination effect; Clean the base powder on the back of the ceramic tile.

[0063] Specifically, in the step (3), mix cement, sand and water in a weight ratio of 1:3:1 and add 5% - 10% by volume of foam particles with a diameter of 3 - 5 mm. Stir by mechanical stirring or manual stirring to ensure that the foam particles are evenly distributed in the cement mortar.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
