AI Technical Summary
The existing reinforced concrete structures are difficult to meet the needs of earthquake resistance, disaster resistance, energy conservation and environmental protection in large-span buildings, and there are problems of material waste and space occupation.
The hidden beam -free large span steel concrete structure is adopted. By increasing the high span ratio of the beam and the multi -layer floor tie, combined with the industrial -shaped beam or multiple industrial font beam structures to form a stable load -bearing system, and at the partition wall of the household partition wall Use reinforced concrete prefabricated thin plate structure.
Realize the earthquake resistance and disaster resistance of large -span buildings, save building materials, reduce space occupation, and also have good ventilation and breathability and natural current effects, reducing energy consumption.

Abstract
Description
[0001] The hidden beam and column-free large-span reinforced concrete structure is a new type of building structure. The structure is not much different from the traditional structure, but a small change brings great changes in the architecture. 1. Technical Field
[0002] Building Structure 2. Background Technology
[0003] Solve the problem of large span of reinforced concrete structures. III. Summary of the invention
[0004] Increase the span of the reinforced concrete structure of the house from the current 6-7 meters to 10-60 meters (if carbon fiber concrete is used, the span can be further increased).
[0005] This structure makes full use of the characteristics of house construction, artistically combines architecture and structure, and becomes a strong and solid structure - a large-span reinforced concrete structure with hidden beams and no columns. The load-bearing system is: plate-beam-exterior wall (plus attached columns)-foundation. The characteristics of this structural system are strong structure, no waste of building materials, saving building space, good earthquake resistance and disaster resistance. It can be built into a ventilated and breathable natural convection (energy-saving and environmentally friendly) building. It can be used in low, medium and high-rise buildings.
[0006] The basis for this structure being strong, not wasting materials and saving building space is as follows:
[0007] 1. Large beam height-span ratio: Change the household partition wall from a masonry structure to a reinforced concrete structure with a large-span beam (one beam has two uses and does not waste materials), and the beam height-span ratio can be 1 / 3 or more (does not occupy building space).
[0008] 2. High stability of the beam: The beam structure is an I-beam or multiple I-beams. Because the flange width of the thick floor beam is relatively large, and each beam has multiple layers of floor slabs and the beam web is equipped with encrypted web reinforcement, its stability is higher than the existing T-beam.
[0009] The basis for the good earthquake and disaster resistance of the structure is as follows:
[0010] 1. Good earthquake resistance - the beam has a large height-span ratio, and the beam has multiple floors with huge torque resistance and high stability. Since the partition walls are replaced by reinforced concrete beams, the indoor partition walls use reinforced concrete prestressed prefabricated thin plate structures, without loose (brick and stone) structures, there will be no brick wall collapse and injury in the house during an earthquake.
[0011] 2. Good fireproof performance - Since the beams (partition walls) and boards are thick, the fire is not easy to burn to adjacent units. There are large-span overhead layers every 2-3 floors to prevent the fire from burning upwards.
[0012] 3. The structure is strong enough to withstand strong external impacts such as mudslides.
[0013] 4. Drawings of the Instructions
[0014] Figure 1 It is a floor plan. Figure 2 It is the second floor plan. Figure 3 It is a three-story floor plan. Figure 4 It is a four-story floor plan. Figure 5 It is a five-story floor plan. Figure 6 It is a six-story floor plan. Figure 7 It is the reinforcement diagram of the second floor slab. Figure 8 It is the 1-1 main structure section, Fig. 9 It is the 2-2 main structure section, Fig.10 This is a diagram of the indoor partition wall structure. V. Specific implementation methods
[0015] Design example: A clubhouse: The first floor is designed as a large-span overhead floor with a span of 30 meters and a length of 50 meters, and the beam height is set to 9 meters. The second and third floors are designed as suite floors, with each floor height of 4.50 meters and a total height of 9 meters. The beams are used as partition walls for suite floors. The fourth floor is set as a large-span overhead floor, and the fifth and sixth floors are suite floors. Just continue to copy when you need to build a high-rise building.
[0016] This building structure is suitable for medium and high-end villas (huge space, no visible beams and columns in the building space, easy to decorate very luxuriously), large high-rise conference venues (the space in the venue is 60 meters wide and 200 meters long or longer), restaurants, sports training bases, sports competition venues (eating, living, training and competition in one), and urban residential high-rise buildings (buildings with sports venues, excellent earthquake resistance, fire resistance and disaster prevention performance).
[0017] Because the suite is slender and has a convection ventilation duct (natural wind), it will produce strong convection and is particularly ventilated and breathable. There is no need to turn on the air conditioner on hot days, which is environmentally friendly and energy-saving.
