Abstract
Description
Technical Field
[0001] This utility model relates to the field of house repair technology, and in particular to a tile waterproof layer structure for outdoor terraces. Background Technology
[0002] In the tiling construction of outdoor terraces, kitchens or bathrooms, stone powder is usually used as a leveling layer for leveling, and then a plain mortar made of cement, sand and water in a certain proportion is applied to the back of the tiles for tiling. Finally, grout is used to grout the joints between the tiles.
[0003] In the prior art, Chinese patent (CN211774660U) discloses a terrace waterproofing structural layer, which, from bottom to top, includes a self-leveling cement slurry layer, a first polymer waterproof coating, a polyester fiber cloth layer, a second polymer waterproof coating, and a polyurea waterproof coating. Chinese patent (CN212742959U) discloses a rooftop terrace waterproofing layer system. However, the above-mentioned patented technologies still have the following problems: 1. The layer structure design is relatively complex, leading to increased construction costs; 2. The waterproofing effect of the grouting structure formed between adjacent tiles using existing grouting agents is poor, causing water to easily seep through the grouting and into the underlying plain mortar layer and leveling layer. Furthermore, the waterproofing quality of the existing plain mortar layer and leveling layer is poor, so once the floor slab or floor cracks, water will seep to the floor below; 3. The poor waterproofing quality of the plain mortar layer and leveling layer makes the floor slab prone to efflorescence.
[0004] Therefore, how to provide a simpler and more reasonable structural design for waterproofing layers on outdoor terraces that can better prevent water from seeping through the grout lines, has a better waterproofing effect, and can better prevent efflorescence on the underside of the floor slab has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of the above-mentioned defects of the prior art, the technical problem to be solved by this utility model is how to provide a tile waterproof layer structure for outdoor terraces with a simpler and more reasonable structural design, which can better prevent water from seeping through the grouting joints, has a better waterproof effect, and can better prevent efflorescence on the underside of the floor slab.
[0006] To achieve the above objectives, this utility model provides a tiled waterproof layer structure for outdoor terraces, comprising a base layer and a leveling layer disposed on the base layer; a tile layer is arranged horizontally above the leveling layer, a mortar layer is disposed between the back of the tile layer and the leveling layer, and a grouting structure is formed between any two adjacent tiles of the tile layer using grout; characterized in that; the grout is PS-1 high-strength penetrating reactive backwater repair special material.
[0007] Thus, the above structure is divided into three layers: upper, middle, and lower. The overall layer structure design is simpler and more reasonable, making construction easier. Furthermore, the grout uses PS-1 high-strength, penetrating, reactive, backwater-resistant repair material, which allows the resulting grout structure to better prevent water seepage to the lower layers and to better work with the tiles to form the top waterproof layer.
[0008] As an optimization, the mortar layer is made of a special mortar for seamless anti-seepage of flat bricks.
[0009] In this way, the mortar layer formed by using seamless waterproof mortar for flat tile application has a better waterproof effect than the mortar layer formed by plain mortar in the existing structure. It can better prevent water seepage and form a second waterproof layer. It can also better form a waterproof system with the top waterproof layer and better reduce water seepage to the bottom.
[0010] As an optimization, the leveling layer is made of RM biomimetic high-density self-healing impermeable mortar active masterbatch.
[0011] In this way, the leveling layer formed by using RM biomimetic high-density self-healing anti-seepage mortar active masterbatch has better self-healing ability and can form a third waterproof layer. As a result, the entire structure can better prevent water from seeping in from above, better prevent moisture from seeping to below, and better prevent efflorescence on the floor slab.
[0012] As an optimization, the thickness of the leveling layer is 3-5 cm; the thickness of the mortar layer is 5-8 mm.
[0013] In this way, the thickness range of the leveling layer and mortar layer is more reasonable, which can control the material usage within a reasonable range while meeting the waterproofing effect and saving costs.
[0014] As an optimization, the thickness of the leveling layer is 4 cm; the thickness of the mortar layer is 6 mm.
[0015] This makes the design of the thickness of the leveling layer and mortar layer more reasonable.
[0016] In summary, the grouting structure formed by the PS-1 high-strength, permeable, reactive backwater-facing repair material in the above structure better prevents water seepage from above, allowing the tiles and the grouting structure to jointly form the first waterproof layer. The mortar layer formed by the seamless anti-seepage mortar for flat tile application has a better waterproofing effect than the plain mortar layer in existing structures, better preventing water seepage and forming the second waterproof layer. Furthermore, the leveling layer formed by the RM biomimetic high-density self-healing anti-seepage mortar active masterbatch has better self-healing ability, forming the third waterproof layer. Therefore, the entire structure better prevents water seepage from above, better avoids moisture penetration to below, and better prevents efflorescence below the floor slab. Secondly, the layered structure design is simpler and easier to construct. Attached Figure Description

[0021] like Figures 1 to 3 As shown, a tiled waterproof layer structure for an outdoor terrace includes a base layer and a leveling layer 2 set on the base layer 1; a tile layer 3 is arranged horizontally above the leveling layer; a mortar layer 4 is set between the back of the tile layer and the leveling layer; and a grouting structure 5 is formed between any two adjacent tiles of the tile layer using grout; characterized in that the grout is PS-1 high-strength penetrating reactive backwater repair special material.
[0022] Thus, the above structure is divided into three layers: upper, middle, and lower. The overall layer structure design is simpler and more reasonable, making construction easier. Furthermore, the grout uses PS-1 high-strength, penetrating, reactive, backwater-resistant repair material, which allows the resulting grout structure to better prevent water seepage to the lower layers and to better work with the tiles to form the top waterproof layer.
[0023] In this specific embodiment, the mortar layer is made of a special mortar for seamless anti-seepage of flat bricks.
[0024] In this way, the mortar layer formed by using seamless waterproof mortar for flat tile application has a better waterproof effect than the mortar layer formed by plain mortar in the existing structure. It can better prevent water seepage and form a second waterproof layer. It can also better form a waterproof system with the top waterproof layer and better reduce water seepage to the bottom.
[0025] In this specific embodiment, the leveling layer is made of RM biomimetic high-density self-healing impermeable mortar active masterbatch.
[0026] In this way, the leveling layer formed by using RM biomimetic high-density self-healing anti-seepage mortar active masterbatch has better self-healing ability and can form a third waterproof layer. As a result, the entire structure can better prevent water from seeping in from above, better prevent moisture from seeping to below, and better prevent efflorescence on the floor slab.
[0027] In this specific embodiment, the thickness of the leveling layer is 3-5 cm; the thickness of the mortar layer is 5-8 mm.
[0028] In this way, the thickness range of the leveling layer and mortar layer is more reasonable, which can control the material usage within a reasonable range while meeting the waterproofing effect and saving costs.
[0029] In this specific embodiment, the thickness of the leveling layer is 4 cm; the thickness of the mortar layer is 6 mm.
[0030] This makes the design of the thickness of the leveling layer and mortar layer more reasonable.
[0031] Specifically, the width of the grouting structure is 0.3-0.8 cm.
[0032] In summary, the grouting structure formed by the PS-1 high-strength, permeable, reactive backwater-facing repair material in the above structure better prevents water seepage from above, allowing the tiles and the grouting structure to jointly form the first waterproof layer. The mortar layer formed by the seamless anti-seepage mortar for flat tile application has a better waterproofing effect than the plain mortar layer in existing structures, better preventing water seepage and forming the second waterproof layer. Furthermore, the leveling layer formed by the RM biomimetic high-density self-healing anti-seepage mortar active masterbatch has better self-healing ability, forming the third waterproof layer. Therefore, the entire structure better prevents water seepage from above, better avoids moisture penetration to below, and better prevents efflorescence below the floor slab. Secondly, the layered structure design is simpler and easier to construct.
