Description
Technical field
The present invention relates to a kind of bamboo wood bending component bidirectional eccentric charger and installation method, belong to bamboo-wood structure
Field.
Background technology
Bamboo and wood materials, can be as the head of green building as a kind of natural biological composite material renewable, degradable
Select building materials.Point out according to the research report of Tsing-Hua University and Beijing University of Technology, timber buildings than steel construction energy-conservation 5.3%, than
Xoncrete structure energy-conservation 8.1%, it is minimum on the impact of environment, is green building truly.Subsequently, GB 50005-
The appearance of 2003 " Code for design of timber structures ", and China introduces U.S., the timber structure product of Jia Deng state and technology energetically, is engaged in wood
The company of structural construction and manufacture of materials and sale emerges in large numbers one after another, and related scientific research unit and demonstration project are also increasing year by year.
According to incompletely statistics, the annual production of current China wooden house is about 8000 sets, and presents the trend increased year by year.2011
Year, China builds up in Tianjin in first 4 floor timber structure apartments, and it breaches current specifications, for domestic timber buildings technology to many
Layer, even high-rise development provide good exemplary role.
Additionally, China is the most topmost Chan Zhu state, have the reputation of " bamboo kingdom ".Bamboo wood trophophase is short, environmental protection
Performance height, strength efficiency and rigidity efficiency are high, less energy consumption.Research shows, for intensity and cost, bamboo is considered as nature
The material that in boundary, usefulness is the highest, its tensile strength, up to 370MPa, is equivalent to HRB400 steel tensile strength design load
(360MPa), its elastic modelling quantity is up to 20000MPa.Therefore, the structural elements that bamboo wood is made has excellent mechanical property, if
As building bearing material, the application of bamboo wood will be widened and advance the development of Green environmental-protection building.
Bamboo-wood structure generally uses post and beam structural system, this system have from heavy and light, the rigidity of structure is good, structure is changeable,
Aesthetic property is strong and can cross over the advantage of larger space, therefore has wide development space.Bending component is post and beam structure
The main supporting member of system, its ultimate bearing capacity and deformation determine structural design scheme, and bending component bears the most simultaneously
Axial compression and the effect of biaxial bending, i.e. biaxial eccentric load, therefore study the biaxial eccentric load performance pair of bamboo wood bending component
Advance bamboo-wood structure development significant.
But, existing bamboo-wood structure biaxial eccentric load experimental study method has no report.Bamboo and wood materials also different from
Steel, aluminium can directly be welded to connect, and can merge solidification voluntarily also different from concrete and connect, therefore additional bracket is not allowed
Easily connect with component, and while the method for traditional research one-way eccentric is applying axial compression, apply horizontal force in a direction
As moment of flexure, this method is not particularly suited for bidirectional eccentric.Therefore use the bidirectional eccentric loading scheme which kind of is easily achieved, become
The key issue that can realize is studied for biaxial eccentric load.The present invention can be effectively improved above-mentioned key issue.
Summary of the invention
What the present invention proposed is a kind of bamboo wood bending component bidirectional eccentric charger and installation method, it is intended to overcome existing
