>& gt;& gt; How to choose the doorway stone at the floor joint

what is the doorway stone

in short, the door stone is the stone threshold --- a stone slab that solves the internal and external height difference, solves the transition between two materials, blocks water, and plays an aesthetic role

function explanation

due to the practice of materials in different rooms, the ground thickness is different, resulting in height difference, and some materials are also bad “ End ”. For example, the indoor floor of the living room or aisle is paved with reinforced composite floor, which is about 12-15 thick (8-thick floor + 5-thick floor mat), while the bathroom floor is covered with tiles, including the thickness of cement mortar + the thickness of tiles + the slope making thickness of the ground running water (the correct slope making method of the ground is explained in detail in another article), which is much higher than the floor after completion. At the same time, the toilet should also consider that a small amount of water in normal use should not flow out to damage the floor. In this way, “ Door stone ” Is one of the common solutions

height difference

generally, it is recommended that the doorway is slightly 5~10 mm higher than the toilet floor. It is enough to slightly block the height of the water flow. First, it is beautiful, second, there should be as few bumps under the feet as possible, and third, the bathroom door is the highest point of slope making, and there should be little water

on the lower side, the doorway stone should not be more than 20mm higher than the ground, which is similar to the above reasons. First, it is beautiful, second, there should be less bumps at the foot, and third, the standard stone thickness is usually about 18~20

if the height difference is too high, you can choose thickened stones to customize. Pay attention to whether there are elderly people or people with disabilities at home

material application

stone corners are usually made “ Chamfer ”, That is, grinding a beveled edge is also for beauty and convenience. It is recommended to choose granite as the stone. The material of granite is harder than that of marble and can withstand stepping. If one side of the ground (usually the outside of the toilet room) has stone floor mosaic or stone floor circle sideline, you can also choose similar or the same material, which is more beautiful. Common cheap, solid and well matched stones are Fengzhen black (Inner Mongolia black), Jinan green, sesame grey, etc

attention to structure

during installation, cement mortar is usually used to lay the door stone. In use, I found that the door stone was trampled for a certain time, and sometimes there were cracks in the surrounding cement mortar. Therefore, it is suggested that when laying with cement mortar, a gap should be left on one side of the floor in the bathroom, which is roughly controlled at about 5mm wide. After filling with cement mortar, the surface is slightly lower and concave. After that, use building glue or silicone glue (the material also used to fix sanitary ware) to make a circle. In this way, even if the cement mortar has cracks and separates from the doorstone, when there is water, it will not penetrate from the gap. At the same time, the construction glue or silicone glue can also be used to mark the joint part between the wooden veneer door pocket and the lower part of the toilet floor tile, so as to reduce the chance of moisture extending and penetrating along the floor to the door pocket, causing the lower part of the door pocket to change color and rot
