Anonymous users2024-02-07The stool, its shape resembles a stool, so it is commonly known as a stool, also known as a brace. It is used in the middle of the upper and lower slabs to fix the upper slab rebars. When the thickness of the foundation is large (greater than 800mm), it is not advisable to use a stool, but to use a bracket to be more stable and firm.
Stool reinforcement is not noted on the general drawings, only individual designers design stools, most of them are marked in detail by the project engineer in the construction organization design of its specifications, length and spacing, usually the specifications of the stool are one level smaller than the plate stress bar, such as the plate reinforcement diameter 12 can be used with a diameter of 10 steel bars to make a stool, of course, it can also be the same as the plate reinforcement. The spacing between the longitudinal and transverse directions is generally 1 meter. However, the specific problem has to be treated specifically, if it is a double-layer two-way plate reinforcement is 8, the steel bar stiffness is low, and the distance between the stools needs to be reduced, such as the spacing is @800*800, if it is a double-layer two-way plate reinforcement is 6, the stool spacing is @500*500.
Some slabs have larger reinforcement specifications, such as using a diameter of 14, then the stool spacing can be appropriately enlarged. In short, the principle of the stool setting is to fix the upper steel mesh, which can withstand the load of various construction activities and ensure that the protective layer of the upper steel bar is within the scope specified in the specification. If the height of the slab is less than 50mm, it cannot be processed, and it can be replaced by short steel bars or other materials.
All in all, the setting of the stool should be in line with the principle of sufficient moderation, which can not only meet the requirements but also save resources.

Anonymous users2024-02-06Many people may not have heard of the stool tendon, this is a construction term, because its shape is similar to the stool so called the stool, there is also called the brace bar, which is placed in the middle of the upper and lower layers of steel bars to fix the steel bar layer, so what are the stool tendons set up rent Zheng Fan? I'm going to introduce it to you today.
Usually if the thickness is about 1m, the outer diameter of the stool bar should be greater than 18 cm, and the interval is arranged in a staggered manner, and the outer diameter of the stool bar should be greater than 22 between the thicknesses. If the thickness is between meters, the outer diameter should be greater than 14 cm, and the staggered arrangement should be arranged at intervals of 1 m. If the thickness is there, the outer diameter should be greater than 12, and only need to be arranged at intervals of meters.
Where to use stool tendons.
If the thickness of the floor slab is more than 15 cm and less than 80 cm, it is necessary to use the stool bar, if the floor is too thick or too thin, there is no need to set the stool bar, the stool bar is usually composed of steel bars with a diameter of 8 mm, and a square area must have a stool bar in the chain, and the distance between them can not be too large to play a role, and it is a waste of material if it is too small. Thin floor slabs can be replaced with short steel bars.
What are the consequences of not setting the stool tendons.
If the stool bar is placed in the middle of the two layers of steel bars, the steel bars of the upper layer will collapse when pouring the floor slab cement slurry, which means that the steel bar layers are all together, so it will not work.
What to pay attention to when setting up stool tendons.
1. In the process of building construction, if the construction unit does not specify the practice and installation number of stool bars, it can be set in a conventional way, and the hardness of the stool bars must be able to withstand the trampling of human weight, and the steel bars that are too fine are easy to deform and collapse.
2. In order to avoid disputes with the contractor, the construction unit must go through the relevant procedures and documents for the stirrup, make calculations according to the actual situation, and then confirm with the supervision unit.

Is there a relevant setting specification for pro-horse stool tendons? As follows: Yes, if the thickness is within 1 meter, the outer diameter should be greater than 18 cm, and the middle interval is staggered; If the thickness is about meters to meters, the outer diameter should be at least 22 cm or more; If the thickness is within meters to meters, the outer diameter must be more than 14 centimeters, and the middle must be separated by 1 meter and then staggered.
What are the reasons why the stool tendons are not tied firmly1, the steel lap joint is not staggered, and the length is not enoughWhen the beam and the floor steel bar are tied, the length of the joint is insufficient, and it will not be staggered on the same plane. This will reduce the load-bearing capacity of the component and affect the safety of the structure. 2. The displacement caused by the infirm binding is a serious quality problem.
After binding, the rebar can be moved up and down, and when placed on the formwork, the rebar may be heavily tilted or overlapped, resulting in deformation of the rebar. The steel mesh becomes parallelogram, which seriously affects the bearing capacity of the steel. Hope mine can help you <>

1. How to exercise during the recovery period of myelitisThe recovery period of myelitis is mainly to exercise the strength of the limbs and the muscle strength of the back of the spine, the back muscle strength can be used to do the function of the lumbar back muscles, and you can exercise at home, but the recovery of the muscle strength of the limbs requires the use of auxiliary exercise tools, otherwise you will fall down if you exercise, and the weakness of the lower limbs will fall. **Exercise is to be in the case of stable condition, can be assisted by family members to move the limbs, or by the patient himself, by the family to assist standing, do not force, but to persevere, pay attention to energy**, reasonable diet, is also very important. **It is an exercise to reduce comorbidities that cannot be restored after Western medicine hormones cannot recover after pushing patients out of the hospital. >>>More
