Description
Technical field
The present invention relates to the fabric structure of steel reinforced concrete, specifically about a kind of suspension type steel reinforced concrete residential structure.
Background technology
At present domestic and international spring layer dwelling house, when the conventional reinforced concrete structure of general employing designs, this structure floor Vierendeel girder span is big, and can learn according to the mechanics of materials and structural mechanics, square being directly proportional of the calculated bending moment of floor beam and span, so beam span is big more under same load, then must the material section size will increase greatly, waste material increases depth of beam again, thereby has reduced the headway of architecture indoor.When under the situation of equal headway, then building general height promptly increases, and wastes construction material greatly, thereby increases infrastructure investment.And increase the gross weight of building, increase seismic forces, also just reduced the shock resistance of building.And the layout of conventional reinforced concrete structure all needs load bearing wall, the post consistency from top to bottom, so, realize parlor, the bottom large space of spring layer dwelling house, and the room, top is cut apart arbitrarily and is that difficulty realizes.Therefore, in the current architectural design,, make every effort to design a kind of adaptation large bay dwelling house design in order to overcome the defective that exists in the said structure, flexible arrangement, the steel reinforced concrete residential structure of flexible segregation requirement is to satisfy the needs of current domestic and international housing construction development.
Summary of the invention
The invention provides a kind of suspension type steel reinforced concrete residential structure, this structure is applicable to the spring layer dwelling house, can reduce one times of girder steel span, thereby reduce the girder steel section significantly, improve the building headway, save steel, alleviating dead load, is a kind of novel residential structure system.
Suspension type steel reinforced concrete residential structure of the present invention, mainly comprise beam, post and superstructure, described main structure body is large bay Special-Shaped Pillar Frame of Reinforced Concrete or special-shape column-short-shear wall structure, wherein superstructure has reinforced concrete floor and steel work superstructure, and the steel work superstructure hangs by the steel pipe suspension rod and is connected the reinforced concrete floor below.For example in the spring layer dwelling house, odd number floor lid adopts large bay prestressed reinforced concrete superstructure, and even numbers floor lid adopts the steel work superstructure, and reinforced concrete floor is connected by suspension type steel pipe suspension rod with the steel work superstructure.Described steel pipe suspension rod hangs and connects, and is to finish by steel pipe hanger rod connecting piece (consulting utility application 03229420.4).The girder steel of steel pipe suspension rod and lower floor's steel work adopts and is welded to connect, and must guarantee the steel pipe suspension rod is vertically installed.From mechanics viewpoint, the steel pipe suspension rod be being connected of top reinforcement concrete floor system and lower floor's steel work superstructure hinged, thereby guarantee that the steel pipe suspension rod is in tension state all the time.The steel pipe suspension rod can require according to architectural design, be provided with flexibly, so that room, spring layer top can reach the requirement of cutting apart arbitrarily.The steel pipe suspension rod can require to be arranged in the partition wall of room according to dwelling house, has guaranteed the fire protection requirement of the attractive in appearance and steel suspension rod of finishing.
Suspension type steel reinforced concrete residential structure of the present invention, when building storey can adopt the shaped pile frame agent structure in time below eight layers, when building storey greater than eight layers and then should adopt the agent structure of shear wall with short piers during less than 16 layers.
Hetermorphiscal column and shear wall with short piers be plesiomorphism in fact, stipulates in the building structure field, and hetermorphiscal column limb length is less than 5 times of wall thicknesses, and shear wall with short piers limb length is at 5-8 times of wall thickness, so short-shear wall structure can bear bigger load.
The steel work superstructure of suspension type steel reinforced concrete residential structure of the present invention, the combination steel work superstructure that can adopt light weight aggregate concrete, profiled sheet and girder steel to form then makes structure of the present invention can obtain better effect, and promptly structure self is lighter, and rigidity is big, and sound insulation, vibration isolating effect is better.
Advantage of the present invention:
Suspension type steel reinforced concrete residential structure of the present invention provides new design approach for spring layer dwelling house complicated and changeable, because the flexibility that the flexibility of steel work and steel pipe suspension rod are arranged, for civil engineering is fitted up integrated, many-sided different resident families, different finishing that requires of adapting to, separating arbitrarily provides wider possibility.
Suspension type steel reinforced concrete residential structure of the present invention sees to be initiative from building structure field.When being used for the spring layer dwelling house, the girder steel span reduces one times, thereby the girder steel section also reduces significantly, so both economical with materials greatly reduced depth of beam again, thereby the headway of architecture indoor is improved, when under the situation of equal headway, then adopt the spring layer building general height of suspension type steel reinforced concrete residential structure to reduce,, reduce cost of investment so can save construction material greatly.Alleviate the own wt of this body structure again, can be implemented in the six layers of dwelling house in Shanghai soft soil area need not drive piles, can control the requirement of settling amount less than 150mm, thereby saved the pile foundation investment, shortened the duration, had very big economic benefit, because the weight of building reduces greatly, also reduce seismic forces, improved the shock resistance of building.
By structural test research, the structural calculation analysis especially by the construction practice of pilot project, can demonstrate fully security reliability and economic rationality that structural system of the present invention is used for dwelling house.
Show that by pilot project design science of the present invention has adopted suspension type steel and concrete structure superstructure dexterously, make spring layer dwelling house Large Space at Lower Part parlor spaciousness, bright.The steel pipe suspension rod can require to be provided with and be embedded in the partition wall of room according to dwelling house, has guaranteed the attractive in appearance and steel suspension rod fire protection requirement that finishing cuts off.
By calculating, structural test and pilot project, show structural system of the present invention under close slightly high situation with general brick mix structure cost, structure durability, anti-seismic performance all are much higher than brick mix structure.
In addition, as everyone knows, the tensile property of steel is more than 100 times of concrete tensile strength, the suspension type steel and concrete structure has then been given full play to the good characteristics of steel suspension rod tensile property, more because the suspension type steel and concrete structure makes suspension rod dexterously, form hingedly with superstructure up and down, make suspension rod under any circumstance keep tension, thereby brought into play the good advantage of steel tensile property.
