What is brick-concrete structure
Brick-concrete structure refers to the use of brick or block masonry for the walls and columns of the vertical load-bearing structure, and the reinforced concrete structure for the transverse load-bearing beams, floors, and roof slabs. In other words, the brick-concrete structure is a structure that bears a small part of reinforced concrete and most of the brick walls. Brick-concrete structure is a kind of mixed structure. It is a mixed structure system that uses brick walls to bear the load and reinforced concrete beams, columns and slabs. It is suitable for buildings with small bay depth, small room area, multi-storey or low-rise buildings. The load-bearing wall can not be changed, while the frame structure can be changed to most of the wall.
Features of brick-concrete structure
In terms of the robustness of brick-concrete structure, theoretically speaking, the firmness of frame structure is greater than that of brick-concrete structure. Therefore, when the brick-concrete structure is designed, the building height cannot exceed 6 floors, while the frame structure can achieve dozens of floors.
However, in the actual construction process, the state stipulates the earthquake resistance level that the building must reach, whether it is brick-concrete or frame, it must reach this level, and even if the developer uses the frame structure to build the house, it will not be used to improve the building’s rigidity. Increase investment, as long as it meets the seismic level. In terms of sound insulation effect, the sound insulation effect of brick-concrete houses is medium. The sound insulation effect of frame structure depends on the choice of partition materials. Some advanced partition materials have better sound insulation effects than brick-concrete, while ordinary partition materials such as cement Hollow panels and the like have poor sound insulation.
Advantages of brick-concrete structure
The brick-concrete structure is convenient for local materials. Bricks are made by firing clay. The clay for making bricks and the fuel such as coal and firewood are almost everywhere. Therefore, brick and tile factories can be said to be everywhere, and brick-making technology is relatively popular, and bricks can be made everywhere. Sand and stone are also local materials. It can be said that where there are mountains, there are raw materials for sand and gravel, and some rivers, lakes and seas can also be found in sand. The brick-concrete structure is convenient for construction. The masonry of brick walls only requires skilled workers to perform manual operations, and when the floor slab adopts prefabricated perforated panels, it does not require special mechanical equipment.
It is suitable for the construction of mountainous areas and small towns, and it is also suitable for the reconstruction of neighborhoods in old cities. The brick-concrete structure is cheap. Compared with cast-in-place reinforced concrete, brick-concrete structure can save a lot of cement, steel and wood. In the cold season, the lowest cost freezing method can be used for construction. It uses many local materials, short transportation distances and low prices. Brick-concrete structure is fire-resistant and durable. Masonry has good fire resistance and good durability. Therefore, in terms of development trend, brick-concrete structure is still an irreplaceable building structure.
