How much can it "sink"? What does this Shen mean?

Do the math how much it will cost you to renovate your home

Nowadays, everyone goes directly to buy the existing house, and they don't know much about the floor slab of the house, such as a standard for the floor slab to bear the load, I believe most people don't understand. So, let me share the load-bearing standards of cast-in-place floor slabs for you, and you can understand them.

1. Cast-in-place floor slab load-bearing standards.

The Code for Building Structural Loads has clear provisions on this, and the live load required in the cast-in-place floor slab of each square meter of building destruction bureau, that is, the design live load of the cast-in-place floor slab is about 200 kilograms, and when calculating the bearing capacity of the floor slab, this load also needs to be multiplied by a load partial factor, which is generally taken as one point four. Specifically, it is necessary to calculate the load-bearing according to the size and density of the steel bars used in the floor slab, the thickness of the designed cast-in-place floor slab, and the concrete number used. In addition to this, there are the following aspects to pay attention to:

1. It depends on the diameter of the steel bar and the thickness of the formwork.

2. The formwork material of the cast-in-place floor slab is different, and it is calculated according to the square meter according to the area of contact between the concrete and the formwork.

3. The height of the formwork of the plate is within 3.6 meters, and the part beyond 3.6 meters is calculated according to the excess part to increase the amount of support.

4. The cavity with a single hole area within 0.3 square meters on the template does not need to be deducted, and the template does not need to be increased. If the area of a single hole is outside 0.3 square meters, it needs to be deducted, and then the template is increased according to the area.

2. What is the bearing capacity of the floor slab of ordinary commercial housing?

1. According to national regulations, the residential floor slab shall not be less than 200 kilograms per square meter. If it doesn't matter much if it's a little bit exceeded, it can be up to 300 kilograms, and it's not advisable to exceed too much.

2. There are very few single items in the house that exceed 200 kilograms, if there is a special phenomenon, we can add a mat under the item, the mat should be larger than two square meters, and the floor slab can be well shared.

3. According to 2000kN, the live load value of the floor slab is different according to the different functions, such as: teaching buildings, canteens, factories, warehouses, etc., the value is higher than that of our living room.

Article summary: The above is the relevant content of the cast-in-place floor slab load-bearing standard shared for you, and it will be shared here for you. Specifically, it is necessary to calculate the load-bearing according to the size and density of the steel bars used in the floor slab, the thickness of the designed cast-in-place floor slab, and the concrete number used.

How much does the prefabricated floor slab and cast-in-place floor slab each bear.

Kiss! Hello, happy to answer your <>

Respect the old gods, the prefabricated floor slab has a load of 1kn m, and the cast-in-place floor slab has a load of 200 kg per square meter. The method of prefabricated floor slab reinforcement: the method of increasing the floor slab section can be directly adopted:

The first is to add a reinforced concrete adhesive layer with a thickness of not less than 40 mm to the surface of the prefabricated floor slab and the bottom of the floor slab, so that the effect of reinforcement can be achieved. In the second type, the carbon fiber cloth is reinforced by the slab, and the fiber cloth is pasted to the tensile part in the direction of the prefabricated floor slab. The third is to paste the steel plate method blindly, which is a bent member plate, which can increase the bearing capacity, I hope mine can help you <>

If you have any other questions, you can ask me again<>

Summary. Dear, we have consulted with you to help you with the load-bearing capacity of prefabricated and cast-in-place slabs depending on their materials and design specifications. In general, the load-bearing capacity of prefabricated floor slabs is greater than cast-in-place floor slabs, as prefabricated floor slabs can be reinforced and prestressed more precisely during the production process, thus improving their strength and stability.

At the same time, the materials of prefabricated floor slabs are also relatively stronger and more durable, such as reinforced concrete, prestressed concrete, etc., so their load-bearing capacity is also higher. Specifically, the load-bearing capacity of prefabricated floor slabs is generally between 2-5 kn m, while the load-bearing capacity of cast-in-place floor slabs is between 1 and 3 kN. However, these figures are only general reference values, and the actual load-bearing capacity needs to be evaluated and determined based on factors such as specific floor materials, design specifications, and construction quality.

Dear, we have consulted with you to help you with the load-bearing capacity of prefabricated and cast-in-place slabs depending on their materials and design specifications. Generally speaking, the load-bearing capacity of prefabricated floor slabs is greater than that of cast-in-place floor slabs, because the prefabricated floor slab side car can be reinforced and prestressed more precisely during the production process, thereby improving its strength and stability. At the same time, the materials of prefabricated floor slabs are relatively stronger and more durable, such as reinforced concrete, prestressed concrete, etc., so their load-bearing capacity is also higher.

Specifically, the load-bearing capacity of prefabricated floor slabs is generally between 2-5 kn m, while the load-bearing capacity of cast-in-place floor slabs is between 1 and 3 kN. However, these figures are only general reference values, and the actual load-bearing capacity needs to be evaluated and determined based on factors such as specific floor materials, design specifications, and construction quality.

Pro, 2 types of floor slabs, how much is the load per square meter?

The load-bearing capacity of the prefabricated back-to-finish floor slab is generally between 2-5kn m, while the load-bearing capacity of the current chain mill poured floor slab is between 1-3kn m.

Dear, there is above.

Converted to kilograms, how much?

The prefabricated floor slab is 200kg-500kg, and the poured floor slab is 100kg-300kg, so if the object occupies half a square area, it is 1 square load multiplied by 1 2?

Dear, so to speak.

Summary. Hello, the load-bearing capacity of prefabricated and cast-in-place floor slabs is determined by their material and structural design. Prefabricated floor slabs are usually made of concrete or reinforced concrete materials, and their load-bearing capacity depends on their thickness, strength, and other factors.

In general, the load-bearing capacity of prefabricated floor slabs can reach about 400-50 0 kg per square meter. Cast-in-place floor slabs are poured concrete on site, and their load-bearing capacity also depends on factors such as the strength and thickness of the concrete. In general, the load-bearing capacity of cast-in-place floor slabs can reach about 300-400 kilograms per square meter.

Hello, the load-bearing capacity of prefabricated and cast-in-place floor slabs is determined by their material and structural design. Prefabricated Xian Dan Ji floor slab is usually made of concrete or reinforced concrete material, and its load-bearing capacity depends on its thickness, strength and other factors. In general, the load-bearing capacity of prefabricated floor slabs can reach about 400-50 0 kg per square meter.

Cast-in-place floor slabs are poured concrete on site, and their load-bearing capacity also depends on factors such as the strength and thickness of the concrete. In general, the load-bearing capacity of cast-in-place floor slabs can reach about 300-400 kilograms per square meter. 

Dear, hello, thank you for your consultation, about your questions, for you to answer as follows: It should be noted that the load-bearing capacity of the floor slab is also affected by other factors, such as the design of the floor support structure, the use environment of the floor slab and other factors. Therefore, in the actual project of carrying and closing, it is necessary to carry out structural design and material selection according to the specific situation to ensure the safe bearing capacity of the floor slab.

The Code for Structural Loads of Building Structures clearly stipulates that the live load of cast-in-place floor slabs should be per square meter, that is, the design live load of cast-in-place floor slabs is about 200kg. When calculating the bearing capacity of the floor slab, this load needs to be multiplied by a load partial factor, which is generally calculated according to the size and density of the reinforcement used in the floor slab, the thickness of the designed cast-in-place floor slab, and the concrete number used. In addition, the following aspects need to be noted:

1.It depends on the diameter of the rebar and the thickness of the formwork. 2.

The formwork material of the cast-in-place floor slab is different, and it is calculated according to the contact area and square meters of the connection between the concrete and the formwork. 3.The formwork support height of the plate is within the limit, and the excess part is calculated according to the excess part to increase the support capacity.

4.Voids with a single hole area of less than square meters on the formwork do not need to be deducted, and the formwork does not need to be added. If the area of a single hole is outside the square meter, it needs to be deducted, and then the orange template is added according to the area.

The Code for Structural Loads of Buildings clearly stipulates that the live load of cast-in-place floor slabs should be per square meter, that is, the design live load of cast-in-place floor slabs is about 200kg. When calculating the bearing capacity of the spike base floor slab, this load needs to be multiplied by a load partial factor, which is generally . The bearing capacity is calculated based on the size and density of the reinforcement used in the floor slab, the thickness of the designed cast-in-place floor slab, and the number of concrete used.

In addition, it is necessary to pay attention to the following aspects: it depends on the diameter of the steel bar and the thickness of the formwork. The cast-in-situ floor slab formwork material is different, and it is calculated according to the contact area and square meters between the concrete and the formwork.

The formwork support height of the plate is within, and the excess part is calculated according to the excess part, so as to increase the support energy attack force. Holes with a single hole area of less than square meters on the template do not need to be deducted points, and there is no need to add a template. If the area of a single hole is outside the square meter, it needs to be deducted and then the template is added by area.

Usually when people build buildings, there are strict requirements for the load-bearing of the floor, today I want to share with you what is the load-bearing standard of the cast-in-place floor, and friends who want to know may wish to take a look at the load-bearing of ordinary commercial housing floors!

1. What is the load-bearing standard of cast-in-place floor slab?

According to China's "Building Structure Load Code", the live load required in each square meter of building cast-in-place floor slab is about 200 kilograms. When calculating the bearing capacity of the floor slab, the calculation should be carried out according to the size and density of the steel bars used in the floor slab, the thickness of the designed cast-in-place floor slab and the concrete number used.

2. What is the bearing capacity of the floor slab of ordinary commercial housing?

1. According to national regulations, the floor load of residential buildings should not be less than 200 kilograms per square meter. It doesn't matter much if it's more than a little, it's not okay if it's too much.

2. For residential buildings, it is rare for a single thing to exceed 200 kilograms, so when encountering special circumstances, a mat can be added under the object, and the area of the mat should be greater than 2 square meters, so as to disperse the bearing force of the floor slab.

3. The load-bearing of each square meter of the general floor slab is based on the value of the live load, usually the living room and the living room and other rooms should be based on the load-bearing of 2000kn (close to 200 kg square meters less than 200 kg), according to the different functions of use, the load-bearing value of the floor slab is not the same, such as: school classrooms, meeting rooms of company units, canteens, warehouses, etc., the values of these places are generally higher than the living room.

4. The value of the standard value of the floor slab is ** in two, one is according to Chapter 4 of the national code of "Building Structure Load Code GB 50009-2012", and the other is the local standard, for example, the floor load bearing stipulated by Harbin is much larger than the floor load bearing value stipulated by the state.

Summary: The above is what is the load-bearing standard of cast-in-place floor slabs and what is the load-bearing of ordinary commercial housing floors, I believe that you also have a corresponding understanding after reading the above sharing, if you need to know more about relevant information, please continue to pay attention to Qeeka Home**, will answer for you one by one.
