Anonymous users2024-01-241: Double-layer rebar? Probably talking about the reinforcing steel at the entrance of the hole, right?
There are many holes in the toilet, if you don't use steel reinforcement to strengthen the "double layer", the floor slab will slowly produce structural damage, and there is a small depth of the toilet opening, the load on the toilet floor is relatively large, with a double layer can ensure its sufficient strength, and the use of waterproofing, but there are many toilet reinforcement arrangements are two-way single-layer configuration reinforcement, only in the hole to strengthen the reinforcement, two-way double-layer steel mesh toilet floor slab is not common!
2: There is also the upstairs said that the toilet is a place of refuge, in the time of earthquakes and fires, it is not because the double-layer steel bar is the reason for the toilet refuge, that is: the propagation mode of the earthquake is the wave, divided into transverse waves and longitudinal waves, the general building can resist the longitudinal waves, and the transverse wave "destruction wave" causes the building to shake left and right, the longitudinal wave causes the building to bump up and down, the toilet because of the small depth of the opening "small volume", it is not good to resonate with the seismic wave, so the earthquake damage to a house in the toilet is the smallest, the drum can take refuge!
3: As for the fire, it is entirely because there are very few objects that can be burned in the toilet, and it is most likely that there is a water source! So in the toilet!
4: 99% of concrete components will not produce brittle damage "Suddenly the whole floor slab falls", all of which produce plastic damage "Slowly Broken", if it is broken!
Hope it solves your problem!

Anonymous users2024-01-23Two-way double-layer reinforcement can be controlled to a certain extent by the cracks in the board, thus waterproofing.
In both directions, it is the longitudinal and horizontal reinforcement of the bottom reinforcement and gluten, that is, the reinforcement is arranged in the X and Y directions of the bottom plate and the panel, and each layer of reinforcement is reinforced in both vertical and horizontal directions.
The toilets of domestic projects are relatively small, and when the slab span is small, even if the backfill and other loads are large, the bending moment of the slab will not be very large, so the possibility of slab cracks is not large under the condition that the qualified design and construction quality are guaranteed.

Anonymous users2024-01-22It's not easy, the use of double steel bars is for, the bathroom is a good place to evacuate in the event of an earthquake or fire. I said that you would like to fall from upstairs to downstairs when you go to the bathroom, and it just so happens that the person is also going to the toilet, so it can't be a co-ed toilet.

Anonymous users2024-01-21Bathrooms don't have to be double-reinforced!
Due to the heavy construction practice of the bathroom, the dead load is relatively large, and the reinforcement can be completely matched with separated reinforcement, and there is no need to use a double-layer two-way network, if it is a double-layer steel bar, it doesn't matter!

Anonymous users2024-01-19Single-layer is OK too! Negative bending bars should be set at the intersection of the wall.

Anonymous users2024-01-18It's not necessary.
According to experience, it is mainly considered that there should be negative moment reinforcement around the slab, if it is a two-way continuous plate, the span size of the adjacent room is much larger than that of the bathroom, and the length of the negative moment reinforcement of the bathroom is determined by the span size of the adjacent room. The area of the bathroom is generally small, relative to the upper reinforcement in both directions, if the length of the lower bend part is straightened, the two steel bars are almost connected, and some even must be through the reinforcement. In order to facilitate the construction of blanking, designers sometimes treat it as a through-reinforcement.
So, there is what you call the case of double reinforcement. In addition, there are still stiffeners for opening holes.
Hello, because the slab span of the bathroom and kitchen is generally small, the thickness of the floor slab is thinner, and the waterproof requirements are higher, so the double-layer two-way arrangement of steel bars to avoid cracking of the board surface; In addition, due to the small span of the plate, the economy of negative reinforcement disconnection is not high, so double-layer two-way reinforcement is generally used.
Holes are drilled for exhaust gases.
Privacy, do you want to go to the toilet and be seen by the opposite sex? Speaking of homosexuality, that's to be seen by everyone, isn't it very twisted, the woman is okay, there is a compartment, the man's urine is just a thing, you get on and go into a woman and then she glances at it and then looks away in disgust, don't you feel that your self-esteem is hurt? Hahahahaha......
The bathroom is generally the smallest in the whole house, so the ceiling and other can be effectively supported by the surrounding stress columns, so the probability of collapse is the smallest, but it is best to run to the open area outside the house, and remember to find an object to protect your head when taking refuge in the bathroom.
If the bathroom is too small, you can design the dry and wet separation of the washbasin outside, put the washbasin externally and place it outside the bathroom alone, and keep the toilet and shower room or bathtub in the bathroom, so that not only can the dry and wet partition be easily realized, but also because the washbasin position only occupies a small part of the common part, the aisle will not appear crowded. >>>More
