Description
Technical field
The invention belongs to construction engineering technical fields, are related to a kind of timber buildings, and in particular to a kind of high-rise wood of overhanging
Structural construction.
Background technology
Timber buildings have cool in summer and warm in winter, body-sensing is comfortable, get close to nature, is in beautiful color, energy-saving and emission-reduction, low-carbon environment-friendly,
The advantages that green ecological, there is reinforced concrete structure to build incomparable advantage.But it is special due to wood quality
Property, building storey is constantly subjected to limit.In order to promote building industrialization, country to widely popularize assembled architecture, it is desirable that having
The place of standby condition, advocates development Modern Wood Construction, promotes distinct Chinese characteristics Modern Wood Construction technical system and middle height
Layer timber buildings research, breaks through the bottleneck of the timber buildings number of plies.
The number of plies of timber buildings is mainly limited by fire safety rules,《Architectural fire-protection methods specification》(GB50016-
2014) and《Code for design of timber structures》(GB50005-2003) all regulation timber buildings are not to be exceeded 3 layers, newly promulgate《It is more
High-rise timber buildings technical standard》(GB/T51226-2017) the main supporting member such as regulation wall column is improving fire endurance
In the case of can reach 5 layers, stringenter fire prevention measure should be taken when more than 5 layers and special demonstration should be passed through.Therefore wood knot
Building the permission number of plies built is determined by the fire protecting performance of structure, can only be built 3 layers according to traditional design methods, be met tighter
5 layers can be built when the fire protection requirement of lattice, should be examined into line overrun more than 5 layers.
Invention content
For the above-mentioned problems in the prior art, the present invention provides a kind of high-rise timber buildings of overhanging, this is built
It builds based on concrete core cylinder, timber structure subframe is isolated using concrete structure overhanging superstructure, timber buildings is made to exist
Building the number of plies under the premise of meeting fire safety rules has important breakthrough.
For this purpose, present invention employs following technical schemes：
A kind of high-rise timber buildings of overhanging, including Core Walls Structure, overhanging superstructure and timber structure subframe；The Core Walls Structure position
In the middle part of whole building, as the carrying basis of whole building, height is determined according to the height of whole building；The overhanging
Superstructure is distributed along Core Walls Structure short transverse according to certain intervals, for supporting timber structure subframe；Timber structure subframe position
Between two layers of overhanging superstructure.
Further, the Core Walls Structure is concrete core cylinder, is built using armored concrete, for undertaking whole building
The vertical load of structure, and undertake the wind load and seismic (seismal of horizontal direction.
Further, the timber structure subframe includes up to 5 layers, meets fire protection requirement；The timber structure subframe packet
The beam column of timber structure and the wooden superstructure are included, is supported on the overhanging superstructure, horizontal direction and concrete core cylinder drawknot；Multiple wood
Structure subframe constitutes the high-rise timber buildings of entire overhanging.
Further, the overhanging superstructure adds the structural system of concrete beam plate using Cantilever Beams, the Cantilever Beams by its
The load undertaken is transmitted on concrete core cylinder；The overhanging superstructure is vertically by the high-rise timber buildings isolation of the overhanging
At multiple mutually independent fire compartments.
Further, the Cantilever Beams use steel-concrete combined structure or prestressed reinforced concrete construction.
It is communicated with timber structure subframe as a preferred embodiment, every layer of the concrete core cylinder is equipped with fire resistant doorsets, it is described
Fire resistant doorsets are usually used to be used as traffic aisle, for isolation of preventing fires when fire.
Further, stair and elevator are equipped in the concrete core cylinder, for being used as podium；The concrete core
Heart cylinder is used for as fire prevention, the safety island taken refuge and evacuated.
Further, the cross section size of the concrete core cylinder is according to the floor space and bearing requirements of whole building
It determines.
Further, the cross-sectional shape of the concrete core cylinder can be rectangle, round or ellipse.
Further, the concrete core cylinder is located on specific basis.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) high-rise wood knot may be implemented in the limitation that the timber structure number of plies is breached under the precursor for meeting building fire protection specification
Build the construction built, the specific number of plies according to building function it needs to be determined that.
(2) concrete core cylinder fire protecting performance is superior, and bearing load ability is strong, and it is strong to be especially resistant to horizontal loading ability,
It is the excellent traffic of skyscraper, fire prevention, Waiting space and load-carrying members.
(3) the concrete structure superstructure every 5 layers not only plays load-bearing effect, but also is excellent refuge floor, prevents with vertical
Fiery sectoring function can be effectively prevented fire spread.
(4) the timber structure subframe number of plies is limited in 5 layers, it is not necessary to the fire prevention that special measure can meet specification be taken to want
It asks.In addition, the timber structure subframe number of plies is few, light-weight, bearing capacity also readily satisfies.
(5) structural system is good in economic efficiency.Armored concrete Center-Periphery Structure and overhanging superstructure main material are concrete, are prevented
Fire is good and economical；The timber structure subframe number of plies is few, light-weight, material utilization amount is few；The combination of concrete and timber makes the two
Each its ability to the greatest extent brings out the best in each other.
