Description
Technical field
The invention belongs to civil engineering structure fields, and in particular to a kind of modern times bamboo structure house, wooden frame structure and bamboo
A kind of steel clamp plate spreading bamboo wood beam that wooden frame structure uses.
Background technique
With increasingly sharpening for global energy crisis and environmental degradation, health environment-friendly, apparatus for energy-conserving ecological type building have become generation
The important directions of various countries, boundary sustainable development.The comprehensive utilization of green building and agricultural-forestry biomass resource has become major fields
And preferential theme.Bamboo structure has good anti-seismic performance and environmental-protecting performance, increasingly attracts people's attention, and meets building row
Industry is comprehensive, coordinates, the requirement of health and sustainable development.
Overlength bamboo wood beam can not use Automobile Transportation, and in actual use, in order to meet wanting for span
It asks, generally requires to carry out spreading to bamboo beam.Traditional spreading method mainly includes metal tooth plate, nail and Tenon, but these three
The reliability of spreading method is low, bearing capacity is insufficient, is easy to cause whole beam that the catastrophic failure integrally collapsed occurs.Its
Reason has: (1) bearing capacity of metal tooth plate and nail is lower, easily corrodes；(2) hardness of bamboo wood is larger, metal-toothed
Plate and nail can not be directed through the surface layer of bamboo wood, be not easy to construct；(3) Tenon joint structure is complicated, the company of often resulting in
It connects unreliable or is not connected firmly.For tooth plate node, nail and Tenon node lengthening bar, steel clamp plate spreading bamboo wood
Higher bearing capacity, initial stiffness and better ductility can be obtained.
Summary of the invention
Purpose to be solved by this invention is to overcome traditional spreading bamboo beam to solve the above-mentioned problems of the prior art
The disadvantages of bearing capacity is low, ductility is poor and deformation performance is poor, provides that a kind of mechanical property is good, low in cost and structure is simple
Steel clamp plate spreading bamboo wood beam, can be used as floor beam and roof girder is applied in bamboo-wood structure building.
In the present invention, steel clamp plate spreading bamboo wood beam, including Zuo Liang, You Liang, steel clamp plate, steel sleeve, nut, screw rod
And gasket, in which: left beam is located at the left side of lengthening bar, and right beam is located at the right side of lengthening bar, and steel sleeve is placed in Zuo Liang and You Liang
In the bolt hole of end, steel clamp plate is arranged in the two sides of beam in pairs, is connected between steel clamp plate and Zuo Liang and right beam with adhesive, together
When with nut, screw rod and gasket reinforce.
Basic principle of the invention is as follows: steel sleeve being embedded into the bolt hole of Zuo Liang and right beam, Zuo Liang, right Liang Yugang
It is connected between clamping plate with adhesive；Screw rod is inserted into steel sleeve, and both ends are anchored at steel clamp plate two sides by gasket and nut.To beam structure
After part is completed, the pretightning force of bolt reaches gasket by nut, and gasket generates precompression to beam and steel clamp plate from two sides.When
When combined joint stress, bamboo beam will prevent its opposite sliding with the frictional force at steel plate interface and adhesive force, at this time connectivity
High-strength friction bolt connection can be similar to.After frictional force and adhesive force are overcome, steel clamp plate and bamboo beam will occur relatively
Sliding, individually resists external load by bolt at this time, and the switching performance of node is connected similar to plain bolt.Compared to tooth plate node,
For nail and Tenon lengthening bar, steel clamp plate spreading bamboo wood can obtain higher bearing capacity, initial stiffness and more
Good ductility.
The left beam is located at the left side of lengthening bar, and right beam is located at the right side of lengthening bar, Zuo Liang and right beam section size phase
Together, the gap of Zuo Liang and right beam end is 10mm or so.
The end of the Zuo Liang and right beam open up the bolt hole of equidistant arrangement in advance, and diameter of bolt hole is equal.
The steel sleeve is placed in Zuo Liang and the bolt hole of right beam end, and steel sleeve is made of Q345 steel, steel
The outer diameter of casing is 1.0mm~1.5mm smaller or so than the diameter of bolt hole.
The viscose glue interface of the Zuo Liang and right beam should carry out dabbing processing, and chisel depth is 1~2mm, and chisel trace is about 20mm,
Cutting rate is not less than 80%.
The steel clamp plate is centrally arranged in pairs in the two sides of beam, steel cleat heights ratio Zuo Liang and the small 20mm of right depth of beam
Or so, the bolt hole that setting matches with Zuo Liang and right beam end distribution positions and dimensions on steel clamp plate, steel clamp plate uses Q345
Steel production.
It is connected, while being reinforced with nut, screw rod and gasket, spiral shell with adhesive between the steel clamp plate and Zuo Liang and right beam
The diameter of bar is 2.0mm~2.5mm smaller or so than the diameter of bolt hole.
The adhesive should select crosslinking binder, using epoxide-resin glue, urea-formaldehyde resin adhesive or phenolic resin glue.
The present invention has widened the application field of bamboo wood beam, overcomes the one of metal tooth plate, nail and Tenon lengthening bar
A little known disadvantages, Steel plate extension bamboo wood beam have following significant effect:
(1) raw bamboo is lower in the added value of product and technology content of traditional field, and bamboo is processed into bamboo wood and is answered
For engineering field, the application field of bamboo can have greatly been widened, has been conducive to vast bamboo producing region additional income.
(2) adhesive and high-strength bolt are used for bamboo wood beam spreading, adhesive can be given full play to and high-strength bolt is anti-
The high advantage of bearing capacity is cut, and greatly improves the initial stiffness and ultimate bearing capacity of spreading beam.
(3) relative to masonry structure and reinforced concrete structure, steel clamp plate spreading bamboo wood beam produces and process
Environmental pollution is small, reduces the usage amount of non-renewable resources, reduces the energy-output ratio in use process；It is tied relative to wood
Structure, bearing capacity is bigger, and span ability is stronger, and automatic recovery ability is more preferable.
