Description
Technical field
The present invention relates to a kind of bamboo-concrete combined component, especially a kind of bamboo-concrete combination beam of combined type connection
And manufacturing method, belong to civil construction field.
Background technique
Bamboo wood is a kind of native organism, has the characteristics that intensity height, light weight, renewable and environmental-friendly, with timber
It compares, there are the basic performances such as the higher ratio of strength to weight, better wearability and relatively low expansion rate of water absorption, intensity is compared with one
As timber it is high by 50~100%, specific strength is 1.5~2.5 times of China fir, is 2~3 times of medium carbon steel.China's bamboo timber resource is abundant,
The speed of growth of the excellent in mechanical performance of bamboo, bamboo wood is fast, is real renewable green resource, the exploitation and benefit of engineering bamboo wood
With the material discrete problem for overcoming raw bamboo, bamboo wood is allowed to be applied to structural engineering field.Since new century, bamboo knot
Structure has obtained developing relatively broadly as a kind of new structural systen in fields such as building, bridges.
The stress performance and timber structure of bamboo structure have certain similitude: Deformation Control Design, load totally carry water
It puts down low.To improve bamboo structure performance, the relevant technologies propose FRP enhancing bamboo structure, however, FRP enhancing bamboo structure is still rigid
Spend control design case.Bamboo and concrete combined structure by bamboo wood and concrete with connector in conjunction with work together, undoubtedly solve bamboo
The effective way of rigidity of structure control design case, has given full play to the superior tensile property of lower part bamboo wood and top concrete is stronger
Compressive property, possess better mechanical property, for bamboo-concrete combined structure, connection type is both to make collaboration work
The key of work.
Due to the material properties of bamboo wood, the connection of bamboo wood and concrete is difficult to realize complete rigid between bamboo wood and concrete
Property connection or realize that preferable rigidity is connect with preferable ductility simultaneously, such as Chinese patent " 201220551921.3 " number, openly
A kind of semi-assembly bamboo-concrete composite bridge, cast-in-place concrete layer are vertical with bamboo respectively by stringer recess, crossbeam recess
Beam, bamboo crossbeam form mechanical snap, and metalwork is equipped in stringer recess, crossbeam recess, guarantee cast-in-place concrete layer and bamboo stringer,
The co-operation of bamboo crossbeam, however, the recess of the combination beam cross section overall with setting bamboo stringer, bamboo crossbeam are caused it is biggish
Damage, recess are easy to be destroyed first by concentrated stress, and recess production need to specially set up template, and construction is complicated, and metalwork is set
In recess inside concrete, recess concrete lacks necessary constraint, in load bearing process, due to recess concrete cracking, metal
Part is difficult to play a role.
Summary of the invention
It is main to apply the object of the present invention is to provide the bamboo-concrete combination beam and manufacturing method of a kind of connection of combined type
In solution bamboo-concrete combined structure connectivity problem.Several bamboo trunks are pasted on the bamboo hole of bamboo beam using adhesive by the present invention
In, the concrete slab with preformed hole is poured, after the completion of concrete slab maintenance, splicing assembling concrete slab and Zhu Liang, in bamboo
Reinforcing rib is arranged in the inside of pipe, and high-strength filler material is then poured in preformed hole and bamboo trunk, realizes the company of concrete slab and bamboo beam
Combination is connect, the present invention is efficient with bamboo beam using natural raw bamboo bamboo trunk and reinforcing rib, high-strength filler material combination realization concrete slab
It is reliably connected, high-strength filler material provides the shear stiffness of connector, and reinforcing rib offer connector is cut blending forming technology, naturally
Raw bamboo bamboo trunk provides effective hoop constraint for the concrete in bamboo trunk, avoids the concrete premature degradation in bamboo trunk and causes to add
Strengthening tendons are difficult to play a role, meanwhile, natural raw bamboo bamboo trunk provides the pin joint pipe of the large scale hollow form of cheap high rigidity,
And natural raw bamboo bamboo trunk provides the template of connecting member forming, and preformed hole changes in up big and down small step, by upper and lower
Build-in mechanism the resistance to plucking carrying between concrete slab and bamboo beam be provided act on, avoid bamboo beam and concrete slab from separating above and below.This
Bamboo-concrete combination beam connector material of invention is natural raw bamboo bamboo trunk and reinforcing rib, high-strength filler material, material source letter
Single, low cost, construction are convenient.
The present invention provides a kind of bamboo-concrete combination beam of combined type connection, it is characterised in that including bamboo beam, concrete
Plate, bamboo trunk, high-strength filler material, reinforcing rib, concrete slab are located at the top of bamboo beam, and the top surface of bamboo beam, which is spaced apart, is equipped with several bamboos
Hole, the diameter in bamboo hole and the outer diameter of bamboo trunk are equal, and the lateral surface of the middle and lower part of bamboo trunk bonds build-in in bamboo by adhesive coating
Within hole, the position in concrete slab bamboo corresponding with bamboo beam hole is provided with preformed hole, and preformed hole is in up big and down small step deformation
Change, center line is consistent with bamboo hole, and reinforcing rib is set to inside being longitudinally arranged along bamboo trunk of bamboo trunk, and high-strength filler material pours
It riddles in the preformed hole and bamboo trunk of concrete slab, and wrapped stiffener, the top surface of high-strength filler material and the top surface of concrete slab
It flushes, concrete slab is integrated with bamboo beam by bamboo trunk, high-strength filler material, reinforcing rib interconnection, the resistance to compression of high-strength filler material
Intensity is not less than 80MPa.
