Description
Technical field
The present invention relates to civil engineering structure fields more particularly to a kind of steel plate to enhance the compound CLT plate of bamboo and wood.
Background technique
Develop Green energy-saving buildings and has become world.Timber buildings history culture with higher and artistic valence
Value is a kind of selection for the realization building energy conservation that modern industry is generally acknowledged.Bamboo wood is also more next as a kind of fast-growing fiber high-strength material
Be applied in building structure, steel are widely applied individually to building structure more.It can be seen that bamboo and wood, the steel capital are good
Construction material：Bamboo and wood materials are fibrous material, advantage be it is light high-strength, the disadvantage is that stiffness of structural member is small, rate of utilization of strength is low；Steel
Material is isotropic material, there is good mechanical property, the disadvantage is that cost is high, fire resistance is poor.Bamboo steel and the compound box beam energy of the wooden steel
The intensity of bamboo and wood is enough made full use of, steel plate can increase flexural stiffness of member, improve the rate of utilization of strength of component, make up bamboo and wood structure
The big disadvantage of part bending deformation.
Traditional CLT component has good dimensional stability, fire resistance and heat insulating and sound insulating performance, in view of timber, bamboo
The basic mechanical performance and China's fast growing wood and bamboo timber resource status quite abundant of material and steel, if can make full use of
Local timber and bamboo timber resource enhances the compound CLT plate of bamboo and wood to produce steel plate, then the component ratio of strength to weight and intensity benefit can be improved
With rate.
Summary of the invention
Goal of the invention：For the deficiencies in the prior art, the object of the present invention is to provide a kind of steel plates to enhance bamboo and wood
Compound CLT plate has the high ratio of strength to weight, rate of utilization of strength height and bearing capacity and bending stiffness height etc. compared with traditional CLT component
Advantage, while improving the shearing strength of component.
Technical solution：In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is as follows：A kind of steel plate enhancing bamboo
The compound CLT plate of wood, by 2 layers and with overwood dimension stock and 1 layer and the above bamboo dimension stock perpendicular quadrature assembly, the built-in corresponding number of plies increases
Strong steel plate sticks agent using epoxy resin structural adhesive and suppresses.
Component successively replaces assembly by the wooden component and bamboo component, and bamboo component is made of the parallel gluing of bamboo dimension stock, neutral axis
The glued one layer of steel plate of the every adjacent members interlayer in lower part, steel plate is with plank be overlapped gluing above and below size.
Beneficial effect：A kind of steel plate of the invention enhances the compound CLT plate of bamboo and wood, has both remained the basic of traditional CLT component
Advantage, and each component construction material advantage that can bring into play：Bamboo wood possesses good shear behavior, and bamboo dimension stock is among component
The shear behavior of component can be improved in position；Steel plate has higher tensile strength and rigidity, is placed in the lower wooden component and bamboo components layer
Between the bending stiffness of component, the ratio of strength to weight of bending strength rate of utilization of strength and component can be improved.CLT component can be made to obtain
Widely application.

Specific embodiment
The present invention is described further combined with specific embodiments below.
As shown in Figure 1, a kind of steel plate enhances the compound CLT plate of bamboo and wood, primary structure component part includes along plate length direction
Overwood component 1-1, the lower wooden component 1-2；With the bamboo component 3 of plate length direction quadrature arrangement；And it is distributed in bamboo component lower surface
With the enhancing steel plate 2 of the lower wooden component interlayer.
This steel plate enhances the compound CLT plate of bamboo and wood, when production, first by lower wood component 1-1 tiling, after the increasing of same size
Strong steel plate 2 is placed in above the wooden component 1-2, sticks agent for the two gluing using epoxy resin structural adhesive, then bamboo component 3 is vertical just
It hands over assembly tiling to enhancing 2 upper surface of steel plate, sticks agent gluing with epoxy resin structural adhesive, then overwood component 1-1 is laid in
3 top of bamboo component simultaneously sticks agent gluing with epoxy resin structural adhesive, finally suppresses component with press.
Bamboo and wood of the invention, the connection of steel plate gluing, advantage are：A kind of steel plate of the invention enhances the compound CLT of bamboo and wood
Plate makes full use of the different materials mechanical property of each component part the shortcomings that overcoming in terms of the mechanical property of traditional CLT component
The advantages of, there are higher bending bearing capacity and bending stiffness, improves rate of utilization of strength far and the ratio of strength to weight.
