Description

A paving structure of floor tiles

technical field

The utility model relates to a design category of a building engineering structure, in particular to a design category of a paving structure of floor tiles.

Background technique

In construction projects, the use of floor tiles is increasing. But empty, cracked imaginations are not uncommon. This has a close relationship with materials and construction. The traditional floor brick construction is: (1) spread dry hard ground mortar on the cleaned base floor; (2) pre-pave ground brick, level it with dry hard ground mortar, and compact the ground mortar; (3) remove Pre-paved floor tiles; (4) pour a thin layer of cement slurry on the compacted and leveled dry hard ground mortar; (4) put back the removed pre-paved floor tiles. Due to the large shrinkage and low water retention rate of the cement paste itself, it is easy to pulverize and crack, resulting in hollowing and cracking of the floor tiles, resulting in project failure.

The improvement method currently on the market is: change the cement slurry into a ground brick bonding mortar, and the construction process is: (1) paving dry hard ground mortar on the cleaned base floor; (2) pre-laying ground bricks , level with dry hard ground mortar, and compact the ground mortar; (3) remove the pre-paved floor tiles; (4) apply floor tile bonding mortar on the back of the removed pre-paved floor tiles; (4) put them back Floor tiles that have been backcoated with bonded mortar. The disadvantages of this method are: (1) it is not easy to apply the floor tile adhesive mortar to the large-sized floor tiles; (2) it is more difficult to apply the floor tile adhesive mortar evenly on the back of the floor tiles, so after paving It is easy to hollow under the floor tiles; (3) the thickness of the floor tile bonding mortar is relatively large, which consumes materials and money; (4) it is difficult to level the surface of the floor tiles.

Utility model content

The purpose of the utility model is to design a floor tile paving structure to reduce hollowing and cracking of the floor tile project.

The paving structure of a kind of ground brick that realizes the utility model is made up of base (1), dry and hard ground mortar layer (2), ground brick interface mortar layer (3), ground brick (4) and caulking agent (5) It consists of a dry hard ground mortar layer (2) above the base layer (1), a ground brick interface mortar layer (3) above the dry hard ground mortar layer (2), and a ground brick interface mortar layer (3) above the ground brick ( 4), the gap between the floor tiles (4) is a caulking agent (5). Wherein, the floor tile interface mortar layer (3) is made of cement, active admixture, polymer rubber powder, water-retaining thickening material, fine Composition of aggregate and water repellent, the specific ratio varies according to the water absorption rate, specifications and use environment of the floor tiles; it is a dry-mixed mortar pre-mixed in the factory, and after adding water at the construction site, it is stirred into a thin paste by a machine The caulking agent (5) is also a polymer cement dry-mixed mortar premixed in the factory. After adding water at the construction site, it is stirred by a machine to form a slurry with a suitable consistency, and the width is greater than 2mm when used.

When laying ground tiles: pave the dry hard ground mortar layer (2) on the cleaned base (1); pre-pave the ground bricks (4), level them with dry hard ground mortar, and compact the dry hard ground mortar; remove Pre-laid ground tiles (4); on the compacted and leveled dry hard ground mortar layer (2), pour a thin layer of special interface mortar layer (3) for ground tiles, and spread it; move back the previously removed pre-paved Floor tiles (4), level; fill the joints with sealant (5).

In this design of a paving structure for floor tiles, the interface mortar layer (3) of the floor tiles is a single-component dry-mixed mortar, which can be easily mixed with water at the construction site to form a uniform thin paste slurry, and because the stirred The fluidity of the slurry is very good, it is easy to pour and level, so that the floor tile (4) is easy to level when it is played back; since the cement content in the slurry of the interface mortar layer (3) of the floor tile is much smaller than that of the cement paste, Its shrinkage, cracking, and "pan-alkali" are much less likely; because the floor tile interface mortar layer (3) contains a water-retaining thickener, the water retention rate of the interface mortar slurry is much greater than that of cement paste, and its Moisture is not easily absorbed by the dry hard ground mortar layer (2), which ensures that the cement in it can be fully hydrated, so that the tensile bond strength of the interface mortar hardened body is high, and it is not easy to pulverize and crack; the water-retaining thickener also It can entrain a large amount of air, which not only reduces the bulk density of the special interface mortar layer (3) for floor tiles, saves materials, improves the workability, but also reduces the elastic modulus of the hardened body of the interface mortar, and improves its flexibility and frost resistance. properties, so that it is not easy to crack; because the floor tile interface mortar layer (3) contains polymer powder, the moisture in the floor tile interface mortar layer (3) slurry is getting less and less, one is due to the cement water contained in itself The second is that the dry hard ground mortar layer (2) absorbs water, the third is that the floor tiles (4) absorb water, and the fourth is that when the water is lost to the environment, the polymer loses water to form a film, which not only improves the surface brick interface mortar layer (3) ) The crack resistance and frost resistance of the hardened body also improves its tensile bond strength, so that the floor tiles are not easy to hollow; the water repellent and active admixture added to the floor tile interface mortar layer (3) , can improve the frost resistance and anti-"pan-alkaline" of the project; the color of the floor tile interface mortar layer (3) can be adjusted, so as to meet the needs of various projects; the thin paste floor tile interface mortar layer (3) The slurry is only about 1mm thick, which greatly saves resources; because the floor tile interface mortar layer (3) contains water-retaining thickening materials and polymer rubber powder, it has good flexibility and high cohesive force, so that it will not be damaged due to environmental effects. When the floor tiles (4) are displaced, the gap between the floor tiles (4) and the interface mortar layer (3) of the floor tiles is not easy to be hollowed out or disengaged; since the interface mortar is stirred into a thin paste, it is easy to enter the ground below it during construction. The inside of the dry hard ground mortar layer (2), and it itself contains polymer rubber powder, so that it has a relatively high cohesive force with the dry hard ground mortar layer (2), so that it is not easy to be hollowed out between the two , Take off. Since the joints between the floor tiles (4) are greater than 2 mm, and the joint filler (5) is a flexible material containing polymer, when the environment changes, the floor tiles (4) will not directly bump into each other, thereby effectively avoiding the ground Brick (4) arching phenomenon.
