Description

Threshold structure with water stop sill table, construction method and manufacturing mold

Technical Field

The invention relates to the field of architectural decoration, in particular to a doorsill structure with a water stop sill table, a construction method and a manufacturing die.

Background

In the construction of architectural decoration engineering, the floor of a room in a wet area is basically paved by ceramic tiles, a doorway is paved by threshold stones, and the finishing surface of each threshold stone is 5-8 mm higher than the surface of a tile in the floor of the wet area. The process is not difficult to find that the floors of the wet area rooms (such as toilets, kitchens and washrooms) and the dry area rooms (such as living rooms, bedroom lamps and hospital wards) at the junctions of the wet areas are easy to damp and arch, damp and mildew on skirting lines, the PVC ground is damp and warped, and a large amount of bacteria are bred, so that the service lives of the dry area rooms and the wet area rooms and the comfort level of healthy life of people are seriously influenced by the phenomenon.

The paving of the floor tiles in modern decoration engineering adopts a dry-pasting construction process, namely cement: after the sand is uniformly stirred according to a certain proportion, a proper amount of water is added, and the amount of the water is generally based on that the sand can be agglomerated after being pinched by hands but the sand cannot wet the hands, and the agglomerated dry materials are scattered immediately after being hit. When the floor is paved, the floor still needs to be moistened again by water; the process is used in rooms in a wet area (such as a toilet, a kitchen and a washing room), the intermediate layer becomes a sponge layer due to insufficient compactness of mortar, the water-containing state of the intermediate layer is kept for a long time, water can continuously seep to the outside ground along the sponge layer, and the floors at the junction of the rooms in a dry area connected with the wet area are easily wetted and arched, wetted and moldy on a skirting line, and wetted PVC ground is raised and kicked to form a hollow drum, so that the service life and the comfort degree of the rooms in the dry area are seriously affected.

If the dry-pasting construction is not used, the obvious joint size of a dry-wet area is caused by the fact that the paving thickness is too thick, the surface flatness is difficult to control, a large amount of bubbles are generated due to high moisture, and a plurality of hollows are left after mortar is solidified to influence the construction quality.
