The frame structure refers to the structure formed by connecting steel beams and columns to form a load-bearing system, that is, a frame composed of beams and columns together to resist the horizontal loads and vertical loads that occur during use. The wall structure of the frame structure is not load-bearing and only plays a role of enclosing and separating. The brick-concrete structure and the frame structure belong to different types of building structures. They have different characteristics and also apply to different buildings. So what is the difference with the frame structure of brick and concrete structure is it? How to distinguish brick structure with a frame structure? Know people should not be much of it! After all, this is a question of professional and technical knowledge. If you are interested in this knowledge, then you can look at the knowledge of the masonry structure and the framework structure that I have put together for you. Let's take a look at the differences between the masonry structure and the frame structure .
What is a frame structure
The frame structure mainly refers to the dwellings that are constructed by using reinforced concrete as a load-bearing beam column, together with prefabricated materials such as aerated concrete, pumice, vermiculite, perlite, and earthenware. The method of transmitting the load of the frame column beam is to apply the load to the floor, and then the floor can transmit the force to the beam. Because the beam is on the column, the force received can be transmitted to the column and the column will be The power is basically passed to the foundation, which is probably the way it is. The walls in the frame structure only play the role of separation and enclosing. The role of this kind of force is suitable for the room to enter into a deep, room-free building.
What is a brick-concrete structure
The brick-concrete structure refers to the way in which the main center of the building adopts the method of building block and masonry for the building, column and beam of the load-bearing structure in the process of building the building, and the floor slab, column beam, and roof panel are not used in a common way. The reinforced reinforced concrete structures are taken as a mixed structural system composed of reinforced concrete beams, columns, plates, etc., with a small part of reinforced concrete and most of the weight-bearing structures of the brick walls. The brick-concrete load-bearing components are mainly walls, and the force transmission method is that the floor transfers power to the wall, and then the wall is transmitted to the foundation in the form of load. Suitable for small rooms with deep and small rooms, multi-storey or low-rise buildings.
The difference between brick-concrete structure and frame structure
Load bearing difference
Brick-concrete structure: The weight of the floor is mainly transmitted to the brick walls that support the floor, and then transferred from the brick wall to the foundation.
Frame structure: the weight of the floor is transmitted to the beam, the beam is transmitted to the column, and the column is transmitted to the foundation;
Material differences
Brick-concrete structure: In the past, solid clay bricks were generally used. However, in order to protect arable land, the use of this brick is strictly forbidden in the following year or two. It is now possible to use load-bearing hollow bricks to develop brick-concrete houses, but reliability and technology are mature. Degrees are not as solid as clay bricks.
Frame structure: The inner partition wall is generally a non-load-bearing hollow brick, which is light, but when it is used as an exterior wall, it is insulated and insulated. Beam columns are cast-in-place concrete.
Technical advantages and disadvantages
The brick-concrete structure has high sensitivity to temperature changes and foundation settlement changes, and it is easy to appear cracks of various types of walls, such as under the roof panels, the four corners of windows, the bottom ledge, etc. It can be said that the brick-concrete structure wall Body cracking is a very common problem, but most of it will not affect the structural safety, and the frame structure has fewer problems.
The difference in cost
The framework is the most expensive, followed by the hybrid structure, and the brick-concrete structure is the cheapest. General brick-concrete structure will be cheaper than the framework 100 ~ 200 yuan / m2
Seismic performance difference
Seismic: The framework is the best, the mixed structure is the second, and the brick-concrete structure is the worst. For the low-rise structures with low seismic resistance, for example, below 6 floors, brick and concrete can be considered. If it is 7 degrees or 8 degrees, it is best not to live in bricks and mortar if the economy allows it.
Revelation 1:
Frame structure housing less affected by the earthquake
Guangzhou needs to strictly monitor the quality of village housing construction
“The Mianyang city with a seismic intensity of six degrees could not find a house without cracks.†The identification of houses with an area of ​​nearly 2 million square meters for more than 10 days in the disaster-stricken area is equivalent to the two-year appraisal of Guangzhou City’s housing safety in Guangzhou. Identification team member said. But even so, "Guangzhou squad is still safe in more than 70% of houses identified in Mianyang."
He Wenzhong, the director of the Housing Appraisal Office Zhang Wenguang and other team members said that the impact of the earthquake, the frame structure housing is less affected, most of them are safe, the more serious damage is the brick and wood structure, mixed structure housing, especially It is in rural areas such as county townships. He Wenzhong believes that compared with Mianyang, the housing situation in Guangzhou is much better. “Not only because Guangzhou is the capital city, its seismic fortification intensity reaches seven degrees, it is six degrees higher than that of Mianyang, and there are many houses with frame structure in Guangzhou, especially for high-rise buildings. As a result of the frame structure, people living in high-rise buildings do not need to worry about the 5 or 6 earthquake.
However, He Wenzhong's engineers are more worried about the security of houses in the villages and rural areas of Guangzhou. For this reason, they suggest that we must further strengthen the quality supervision during the housing construction process, especially the strict supervision of housing construction in rural and urban villages to ensure the quality of construction projects. All construction activities must be conducted in strict accordance with the relevant national construction procedures, and strictly comply with the relevant national planning, construction design and construction acceptance norms and standards. “The damage to the houses in the earthquake-stricken area was severe, mainly because of the high magnitude of the earthquake and its high destruction intensity, but it was also related to the lack of design, non-construction supervision, or inappropriate structural selection in the construction process, low construction material strength, and poor construction quality. There is a certain relationship between improper handling of seismic structures."
Revelation 2:
The structure of the house must not be destroyed by "as desired"
Pre-assessment of post-assessment of renovated house
At present, some citizens in Guangzhou are overcharging rents and blindly rebuilding their houses. The phenomenon of “one room changes into several rooms†is frequent. Not only that, but in the meantime the citizens or some units modify the “anything they want,†or even destroy the bearing walls. The Guangzhou housing appraisal engineers who physically felt the damage in the earthquake-stricken areas called on the citizens to avoid any decoration. “Even if earthquakes do not occur, the damaged buildings will also affect the safety of the whole building.â€
The Municipal Housing Appraisal Office proposed to strengthen management and penalties for misconduct in the course of the use of the house, to demolish the main structure of the house without permission during the use of the house, to change the nature of the use of the house, increase the use load of the house, and arbitrarily open the doorway, erection ( Building) The behavior of the structure should be resolutely stopped.
The Municipal Housing Appraisal Office had previously drafted rules concerning the safety management of residential decoration and decoration, and the maximum penalty for violations was 10,000 yuan. Among them, not only residential decoration companies are required to register with the housing management department, but also there is a need to change the structure of non-bearing structures, increase wall masonry, increase the use load of houses, cut non-bearing walls, enlarge or move the size and position of doors and windows, etc. The housing appraisal department records, and the appraisal department of the house after renovation also conducts safety appraisal, and the daily inspection by the property management and residents' committees also finds that the illegal decoration has been stopped.
Editor's summary: In general, the most essential difference between the brick-concrete structure and the frame structure is that the load-bearing components are different. The main load-bearing component of the brick mix is ​​the wall, and the main load-bearing component of the frame is the column beam. In comparison with each other, the frame structure is better than the brick-concrete structure in terms of earthquake resistance, stability, and housing toughness. However, the advantage of brick-concrete structure is that it is cheap and is suitable for multi-storey and low-rise houses. However, in fact, many multi-storey or low-rise buildings, including two- and three-storey villas, are equipped with a frame structure, which also shows that they are safe for human life. Load-bearing structure system, the framework reflects its advantages. It can be said that they have their own advantages and disadvantages, mainly depends on the needs of everyone.
