Abstract
The present invention relates to the buildings in general structure, especially belong to the structural system of multi-storey building.The present invention constitutes the skeleton supporter by the vertical wall limb of the steel concrete of cast-in-place dispersion, outer eaves coupling beam and girderless floor.The axis of building is as vertical supporter grid, and the wall limb is positioned at the intersection point place of grid, and girderless floor is positioned on the vertical supporter.The present invention has cancelled large stretch of solid-walled structure, for house building has been created suitable large space, make the house building plane layout possess sufficient flexibility, thereby solved the aging contradiction aging of housing construction material, also had simultaneously and to alleviate structural weight per square meter, reduce load and to satisfy the advantage of shockproof requirements with function.
Description
The present invention relates to the buildings in general structure, especially belong to the structure of multi-storey building.
The structural system of existing multi-storey building, in the majority with brick mix structure.The supporting role of this structural system is to rely on the some brick load bearing wall that is provided with in the building to bear, and the inevitable room layout of fixing that in housing construction, formed of the existence of these load bearing walls.This structural system has three shortcomings.One: masonry walls from great, anti-seismic performance is low, the area poor for foundation condition, that seismic fortification intensity is high is especially unfavorable.Its two: fire loam brick and need consume useless a large amount of earth, destroy a large amount of good farmlands, make to plough and reducing year by year.Its three: along with The development in society and economy, the variation of family structure, the raising of resident's cultural quality, people are also more and more high for the housing functions requirement.And in China, the substance aging phase of dwelling house is about 5 times of function aging period, and the phenomenon that residential function is out-of-date is found everywhere.And the bearing structural system of this fixedly standard width of a room in an old-style house has fettered the development and the adjustment of the function design of housing construction, causes the versatile and flexible of housing plan to be restricted.
In order to overcome brick mix structure from great, build the few shortcoming of the number of plies, in recent years, the other two kinds of structures that adopt in the residential structure design are: 1. frame light plate structure: i.e. the frame system that constitutes of beam, post and cooperate light wall plate.Light wall plate is divided into again to be cast and two kinds of assembled integrals, and this structural system deadweight is lighter, but cost is higher.The light-duty frame construction of special-shape column: have the framework characteristics, and the beam column section is reduced, the post attenuate is become 150mm, and make "+", " T ", " L " type section, this member section complexity, inconvenience construction, when especially making assembled integral, the frame joint difficult quality guarantee.Though above-mentioned two kinds of form of structure have been abandoned immutable load bearing wall, but because of to indoor outstanding beam, post, the nonbearing partition that is provided with can only influence the flexibility of building plane layout equally by the post network arrangements of the little standard width of a room in an old-style house, and the variation of residential function is restricted.
The objective of the invention is to overcome the deficiency of above-mentioned technology and design a kind of structural system that can create suitable large space and arrange the multi-storey building that sufficient flexibility is provided for house building plane for housing construction.This structural system can not only alleviate structural weight per square meter, can also reduce load and satisfy shockproof requirements.Construction costs is also lower.And undirected indoor outstanding beam, post, for using, the user brings convenience.
The objective of the invention is to realize by following design scheme: it constitutes the skeleton supporter by the vertical wall limb of the steel concrete of cast-in-place dispersion, outer eaves coupling beam and girderless floor.The axis of building constitutes the grid of vertical supporter, the wall limb is positioned at the intersection point place of grid, the size of grid L between 4.2m-6.0m, wall limb thickness b 〉=180mm, width B 〉=4b, its specific design size can be done suitably to adjust with reference to conditions such as grid, load, seismic fortification intensity, places.Outer eaves coupling beam section width is not less than 150mm, highly is not less than 400mm.Girderless floor is positioned on the vertical supporter, and slab thickness is not less than L/30.
The distribution of wall limb in building will and be decided according to the specific design requirement.Generally along the periphery setting of housing unit, the wall limb of arranging in every unit is then decided with the requirement of architectural composition.Partition wall in the building adopts the non-bearing lightweight body of wall with reasonable physical index.This body of wall can make removable.When needs change building function, can arbitrarily change the body of wall position.Like this, all can there be the different unit of style to occur in each floor of every building dwelling house, can cuts off with the lightweight body of wall arbitrarily according to resident's demand separately again in every cover unit, thereby satisfy the different function requirements of resident dwelling house.
Cooperate the girderless floor of this supporter grid can adopt various ways: the one, cast in place reinforced bar coagulation flat board, thickness of slab is decided on the unit weight of the light partition wall that adopted and the size of supporter grid.The 2nd, the cast-in-place two-way close plate that helps, little rib spacing is less, and intercostal adopts light material to fill up, and to alleviate the floor deadweight, the plate total thickness is not less than 180mm, and along the supporter grid solid strip is set.The 3rd, adopt the assembled integral floor, promptly at supporter grid intercropping precast plate, after on-the-spot the installation, cast solid strip and become whole.Arrangement of reinforcement can adopt common hot-rolled reinforced bar, bi-steel in the plate, also can adopt prestress reinforcement.
The present invention's advantage compared to existing technology is:
1. owing to cancelled large stretch of solid-walled structure, adopt a kind of new structural system, can create suitable large space and provide sufficient flexibility for the house building plane layout for housing construction as the skeleton supporter.
2. the present invention adopts the non-bearing lightweight body of wall with reasonable physical index, can alleviate structural weight per square meter, reduces load and geological process, and then reduces cost, can satisfy performances such as sound insulation, heat insulation, insulation again, reaches the Dwellings Buildings'Energy Economizing effect.
3. owing to all not load-bearing of external and internal wall in the structure design, the recent design of being convenient to residential function is made every effort to rationally, and at a specified future date the transformation is easy to realize, thereby solved dwelling house substance aging and the aging contradiction of function.
4. cancelled the load bearing wall of brick mix structure, abandoned using loam brick, the problem that fundamentally having solved bakes bricks ruins the field.
5. employing the present invention can suitably improve the construction number of plies of multi-storey building, saves the area.
