Comparison of the cost of frame structure and brick concrete structure

Of course, it is a frame structure, the cost of the frame is 700-800 yuan m2, and the brick concrete is 400-500 yuan m2Specific data vary by region.

The cost of the frame is higher, depending on the size of the main body, if it is seven floors, the brick concrete is cheaper, if it is a small high-rise, the frame is saved!!

Frame structure construction and brick and concrete structure construction,The difference in cost between the two is about 430 yuan per square meter. Now the economic conditions in the rural areas are getting better and better, whether they are working outside or starting a business at home, many people have built their own new houses, some have built villas, some have built small western-style buildings, and the structures are also diverse, but the most in our hometown is still a brick and concrete structure.

Let me give my opinion from the following points:

First, the characteristics of each

1. The main difference between the two is that the stressed components are different.

In order to ensure the integrity of the brickwork, ring beams are generally added, structural columns are generally added to increase the shear resistance of the brick wall, and wall reinforcing steel bars are added. The main stressed members of the frame structure are beams, plates and columns, and the filled walls are generally made of lightweight materials, which only play the role of partition and are not stressed, but the reinforcement content is much larger than the former.

2. The characteristics of each of the two:

The brick-concrete structure is easy to construct and has low cost, but its own weight is large, the space transformation is poor, and the seismic resistance is poor, so it is generally only used for multi-layer; The frame structure itself is small in weight, about 30% lighter than the former, and has good space transformation, but the disadvantage is that the cost is high, and it can generally be used for multi-storey and high-rise. Now there is also a kind of light steel structure, which is characterized by a short construction period and relatively no advantage in cost.

Second, the difference in cost

Below we only compare the main structure, water, heating, and electricity are not considered for the time being. Because in the actual construction, there are many unforeseen factors, we are just under normal construction conditions, without considering the quality and safety costs, without considering the schedule factors and other external factors, take the main indicators to estimate, after estimation, the difference between the cost of the two is about 430 yuan. I hope it can be used as a reference for you.

In recent years, the cost of land acquisition has become higher and higher, and the state has relevant requirements for floor area ratioFor example, for buildings with less than 7 floors, the floor area ratio does not exceed that, and buildings with more than 11 floors do not exceed the floor area ratio and the building density does not exceed 20%, so the more unit costs of multi-storey buildings are relatively amortized, which is also a major reason why there are fewer and fewer multi-storey buildings in recent years.

Frame structure and brick-concrete structure are two common structures in house construction nowadays. Frame houses will be more durable, so the cost will be higher.

Yes, the materials used in these two ways of building houses are different, and the cost will be much different, and the cost of the frame structure will be higher.

I think there is still a certain gap between the costs of the two, because the materials used are different.

For brick-concrete structures, the load-bearing walls cannot be changed for small, multi-storey or low-rise buildings. The overall force and rigidity of the frame structure are strong, seismic and self-weight. It's better to be in a safe or frame structure.

First of all, the mechanical structure of brick-concrete structure and frame structure is different。Frame structure: There are three types of beam, plate and column structures to match the load.

The biggest feature is "strong columns and weak beams". The simple and popular saying is that all the columns match each other to support the overall weight of the house. Beams and columns combine to withstand local house loads, while slabs bear scattered house loads!

In other words, if the pillars are broken, there will be big problems with the house. Even if the beams and slabs are damaged, they are partial and do not affect the overall structure of the house! Generally speaking, the construction process of the frame structure is to hit the reinforced concrete first, and after the wall is completed, the wall is not load-bearing at all, and can be modified and dismantled at will!

Brick-concrete structures refer to the construction of bricks for the walls and columns of vertical load-bearing structures, while the beams and slabs of horizontal load-bearing structures are constructed of reinforced concrete. That is, a brick-concrete structure is a structure that carries a small portion of reinforced concrete and a large part of the brick wall. As we all know, in the construction industry, red bricks are very strong.

Theoretically, red bricks can be built more than 10,000 meters high and are cheaper, so most rural residents prefer red bricks! In the brick-concrete structure, the load-bearing wall is absolutely not allowed to be disassembled or assembled at will, otherwise the consequences will be unimaginable!

Frame structural columns are the main load-bearing members, and their reinforcement content is high. According to the relevant regulations of the state, the content of self-built villas in general three-storey frame structure is 45 60kg, which fully guarantees the stability and seismic resistance of the overall structure, while the brick-concrete structure is about 20kg, and even the construction team that cuts corners in some places is less.

The welding of steel bars is also very important, especially when the length of the stressed steel bar is insufficient and elongation is required, welding should be used, and the strength of the steel bar at the welded part should not be weaker than the steel bar of the same diameter! There are two commonly used welding methods: resistance pressure welding and double-sided lap welding.

However, in rural areas of our country, there are some small construction teams that require special equipment, and this is because resistance pressure welding is troublesome. Generally speaking, it is very difficult for small construction teams to have these equipment, so the most common is double-sided lap welding.

There is a big difference in the cost of brick-concrete structure and frame structure infiltration. Usually, the cost of a three-storey vacant house is 800 1000 yuan, and the cost of a frame structure house is about 1000 1200 yuan. In addition, the construction period of a frame structure house is about 30% longer than that of a brick-concrete structure.

Which is better, brick-concrete structure or frame structure, should be analyzed from different angles. Because we can't directly say which structure is more suitable and which one is better. So first of all, we should consider what is the main concern of our self-built houses.

1. From the perspective of cost, it is recommended that you choose a brick-concrete structure. In fact, the brick-concrete structure per square meter is about four or five hundred yuan less than the frame structure, and some may even be higher.

2. From the perspective of earthquake resistance of the house, it is recommended that you choose the frame structure. The current self-built houses with brick and concrete structures do not have any seismic performance. Moreover, many of the brick concrete in the self-built house have not undergone strict force calculation, and are directly built according to experience, which leads to the fact that the foundation of many brick and concrete structures does not meet the requirements.

And its foundation does not meet the requirements, its seismic characteristics are even worse. Therefore, if our self-built house belongs to the most frequent area, then try not to choose a brick-concrete structure, but to choose a frame structure is reliable.

3. From the perspective of room size, it is recommended that you choose a brick-concrete structure. In fact, when building a house, many friends will consider the size of the studio. Every room like our self-built house has a living room, dining room, bedroom, kitchen and bathroom.

For each room, we want it to be larger. Therefore, if you choose from the size of the bay, then I personally recommend that you choose the brick-concrete structure. Because the frame structure has strict structural columns, ring beams, and a complete set of frame structure, it will lead to a certain limitation of the span.

Then what happens is that we have a limit on the size of our bays. The size of the bay of the frame structure of the house is indeed not as reasonable as the brick-concrete structure.

4. From the perspective of building floor height, I personally recommend that you choose the frame structure. Especially for self-built houses with more than three floors, the frame structure should be chosen.

What is the difference between brick-concrete structure and frame structure?

1. Different load-bearing methods: the load-bearing structure of brick-concrete structure is composed of slabs and walls, and the frame structure is a load-bearing structure composed of beams, floor slabs and columns.

2. The system is different: the brick-concrete structure is a mixed structural system composed of reinforced concrete beams, columns, slabs and other components, and the frame structure is composed of frame columns.

3. Different structures: the stiffness and strength of the frame structure system are relatively good, it is a flexible structure, and the masonry itself is composed of brittle materials in brick concrete, with poor tensile and shear strength, small deformation resistance, poor ductility, and it is easy to cause damage to the structure, which is a rigid structure.

4. The floor height is different: the brick-concrete structure can achieve up to 6 floors, while the frame structure can achieve 30 floors.

In terms of comparison, the frame structure is better than the brick-concrete structure in terms of stability, earthquake resistance, and toughness of the house, and the frame structure has a large space, which can change the size of the room and is not easy to break the ring.

The differences between frame structure and brick-concrete structure are as follows:

1. The occupied area is different.

Due to the relationship between the walls, the space of the brick and concrete structure is also limited, and the room area is relatively small. The frame structure is a beam-and-column structure, which makes the house space larger, so the house area is larger.

2. **Different.

Since the brick-concrete structure does not need frame pillars, it saves steel and cement, and reduces the cost relatively speaking. The frame structure should use formwork and wood frame, so it is more expensive than the brick-concrete structure.

3. The safety factor is different.

When accidents such as ** occur, the brick-concrete structure is easy to collapse and deform, while the frame structure has a better bearing effect, which can disperse the load and minimize the safety factor.

Common house building structures:

1. Steel structure.

Steel structures are made of steel, including suspension structures, and are also a type of building structure. The overall weight of the steel structure is light, the construction is simple, and it is suitable for steel structure workshops and large gymnasiums.

2. Steel-concrete structure.

The main structure of the steel-concrete structure is built with reinforced concrete, and the material is a mixture of cement and steel bar. For example, one part of the house is made of steel and the other part is made of reinforced concrete, and many high-rise homes are built with this structure, which is more complex and expensive.

3. Frame shear wall structure.

The shear wall replaces the beams and columns in the frame structure with reinforced concrete wall panels, which can support different interiors and effectively control the horizontal force of the structure, which is widely used in high-rise buildings.

1. The load-bearing mode is differentThe load-bearing structure of brick-concrete structure is composed of slabs and walls, and the frame structure is a load-bearing structure composed of beams, floor slabs and columns.

2. The system is different.

The brick-concrete structure is a mixed structural system composed of reinforced concrete beams, columns, slabs and other components, and the frame structure is composed of frame columns.

3. The structure is different.

The stiffness and strength of the frame structure system are relatively good, it is a flexible structure, and the masonry itself is composed of brittle materials in brick concrete, with poor tensile and shear strength, small deformation resistance, poor ductility, and it is easy to cause damage to the structure, and it is a rigid structure.

4. The floor height is different.

The brick-concrete structure can achieve up to 6 layers, while the frame structure can achieve 30 layers.

The differences between frame structure and brick-concrete structure include different load-bearing structures, different safety factors, different transformations, different costs, different floors, different structures, and so on.

1. The load-bearing orange return structure is different.

The load-bearing structure of brick-concrete structure is mainly brick wall structure. The load-bearing structure of the frame structure is dominated by beams and columns.

2. The safety factor is different.

The bearing capacity and seismic performance of the frame structure are better than those of the brick-concrete structure. When there is an accident such as **, the brick-concrete structure is more likely to collapse and deform, and the frame structure is not easy to collapse.

3. The transformation is different.

The walls of brick-concrete structures are mostly load-bearing walls, which cannot be transformed at will. The walls of the frame structure are mostly non-load-bearing walls, which can be flexibly transformed.

4. The cost is different.

Less reinforced concrete is used in brick-concrete structures, and the construction is relatively simple, so its cost will be relatively low. The frame structure will use a large amount of reinforced concrete, and its construction is relatively complex and more expensive.

5. The number of layers is different.

Buildings with brick and concrete structures are mostly 5-6 floors, and buildings with frame structures are mostly high-rise buildings, usually with more than 30 floors, and so on.

6. The structure is different.

The brick-concrete structure is a rigid structure, with poor tensile and shear strength and low deformation resistance. The frame structure is a flexible structure, with good stiffness and strength, and the stress points are relatively scattered.
