With the increase in the housing now head of this thermocline, the emergence of a wide range of indoor plus layer forms, many owners do not know to choose a more appropriate. Because most developers and property management are not permitted to do in-situ concrete, but many owners recognized the cast-in-place reinforced concrete. As I am concerned, all aspects of the cast-in-place reinforced concrete structure is still much better than several other structural forms. As indoor cast-in-place reinforced concrete added layer, especially in high-rise buildings from the total weight of the following comparison: If we say: the 30-story building, each layer 7 family, every family increased by 20 square meters, each square meter about 0.26 tons, the whole building on the increase: 15X7X20X0.26 = 546 tons. If steel and wood structure: ibid, each square meter of about 45Kg; whole building: 15X7X20X45 = 94.5 tons if calculated by Ganghunjiegou: Other ibid every square meter of about 130 Kg; whole building : 15X7X20X130 = 273 tons of from above comparison most owners should clear point of it! Normal design for high-rise buildings are taken into account in the design of the time to the need to increase the weight of the layer, for example: in the past did not appear this thermocline or pick high-rise housing, 30-floor high-rise housing is 30 layers no empty position. Now houses the thermocline, is to do less than 30 layers of more than one thousand square meters of cast-in-place concrete slab. Other structural design is not changed. Compare the following the added layer structure in the form: 1, reinforced concrete structure (advantages: solid structure, stability, stiffness, overall good, long working life. Drawback: Since the material). 2 channel (or I-beam), angle iron, wood combination of steel and wood structure (advantages: shorter construction time, good carrying capacity, light weight. Shortcomings: poor wholeness, poor sound insulation.), Steel combination The hybrid structure of steel mesh and fine aggregate concrete mix (advantages: light weight, stiffness, overall good, short construction time, noise abatement. Disadvantages: slightly higher cost). The wooden structure (advantages: shorter construction time, and light weight. Shortcomings: poor stiffness and noisy, use a short time). In fact, it is reasonable to choose the form of an additional layer, each with its own benefits and drawbacks, as long as the housing structure itself is not the problem; most important thing is to choose a construction team. I hope the above to the owners to bring a little more understanding, a little more choice.
