The utility model discloses a fiber-reinforced hollow wooden column supported by a "cross"-shaped bamboo, which comprises a front wooden member (1-1), a left wooden member (1-2) and a rear wooden member (1-2) along the length direction of the column. 1-3), the right wooden member (1-4); the "cross"-shaped bamboo support (2) built into the column; the reinforcing fibers (3) outside the column body arranged in sections along the length direction of the column. Advantages: Fiber-reinforced hollow wooden columns with "cross" bamboo support are all installed in the factory and transported to the site, which will not cause environmental pollution. Compared with ordinary wooden columns, fiber-reinforced hollow wooden columns with "cross"-shaped bamboo support have higher compressive strength, shear strength and better ductility, and also save materials than ordinary wooden columns. Reduced size requirements, more green and environmentally friendly.
Description
Technical Field
The utility model relates to a civil engineering structure field especially relates to a hollow wooden pillar that "ten" word bamboo in area of fibre reinforcing supported.
Background
Recently, the country advocates to develop green buildings vigorously, the wood structure buildings are paid attention to again, the traditional wood member is an environment-friendly structural member and has the characteristics of light weight and high strength, and the defects of long growth period, more defects such as wood knot cracks and the like cause larger strength discreteness of the member; the basic mechanical properties of various bamboo components, such as strength and elastic modulus, are superior to those of wood components, and the cost is higher than that of wood; the fiber products such as FRP, CFRP, GFRP and the like on the market at present have ultrahigh tensile strength. The production technologies of the materials are mature, modular production and prefabrication can be realized in factories, the installation is convenient and fast, the construction period is short, and the strength is greatly reduced compared with the cost of solid wood components.
China's fast growing wood (poplar, pine, eucalyptus, etc.) and bamboo resources are quite rich, the production technology of various wood and bamboo components is mature, and the fiber products are also already applied to various engineering reinforcements and obtain good effects. If abundant wood, bamboo and fiber products can be fully utilized, the fiber-reinforced hollow wood column with the cross-shaped bamboo support and better mechanical property can be produced, the mechanical property of the wood column can be improved, reasonable resource allocation can be realized, the resource utilization efficiency is improved, and the cost is reduced.
Disclosure of Invention
The purpose of the invention is as follows: to the not enough of existence among the prior art, the utility model aims at providing a hollow post that fibre reinforced's area "ten" word bamboo supported has advantages such as environmental protection grade height, light high strength, compressive strength are high, shear strength is big and the ductility is good.
The technical scheme is as follows: in order to achieve the above purpose, the technical solution adopted by the present invention is as follows: a fiber-reinforced hollow wood column with cross-shaped bamboo supports is characterized in that a front wood component, a left wood component, a rear wood component and a right wood component form the hollow column, the cross-shaped bamboo supports are arranged in the middle of the hollow column, reinforcing fibers are arranged along the length direction of a beam, and epoxy resin structural adhesives are used for pressing and forming.
The front wood member, the left wood member, the rear wood member and the right wood member are formed by selecting wood plates with proper sizes according to the size requirement of the members to combine into a hollow column.
The cross-shaped bamboo support is characterized in that a bamboo component with a proper size is selected according to the size of the component and the bearing capacity requirement and is connected with the front wood component, the left wood component, the rear wood component and the right wood component in the hollow column.
The reinforcing fiber is fiber cloth with proper size and number of layers according to the size and bearing capacity of the member.
The front wood member, the left wood member, the rear wood member and the right wood member are glued by epoxy resin; the front wood component and the cross-shaped bamboo support are glued by epoxy resin; the left wood component and the cross-shaped bamboo support are glued by epoxy resin; the rear wood component and the cross-shaped bamboo support are glued by epoxy resin; the right wood component and the cross-shaped bamboo support are glued by epoxy resin; the reinforced fiber and the hollow column are glued by epoxy resin.
Has the advantages that: the utility model discloses a hollow wooden pillar that fibre reinforcement's area "ten" word bamboo supported can exert respectively and constitute the component material advantage: the fiber has higher tensile strength, and the fiber is coated outside the wood column to improve the shear strength and ductility of the member and the dimensional stability of the member; the bamboo wood has higher compressive strength, and can improve the compressive strength of the component.

Fig. 4 is a schematic view of a fiber-reinforced hollow wood column reinforcing fiber (3) with a cross-bamboo support.
Detailed Description
The present invention will be further described with reference to the following specific examples.
As shown in figure 1, the main structural components of the fiber-reinforced hollow wood column with the cross-shaped bamboo support comprise a front wood component 1-1, a left wood component 1-2, a rear wood component 1-3 and a right wood component 1-4 along the length direction of the column; a cross-shaped bamboo support 2 arranged in the column; and the reinforced fibers 3 are arranged along the length direction of the column in a segmented mode and are wrapped outside the column body.
When the fiber-reinforced hollow wood column with the cross-shaped bamboo support is manufactured, firstly, a front wood component 1-1 is horizontally placed, then, a left wood component 1-2 and a right wood component 1-4 are vertically placed on the surface of the front wood component 1-1 and are glued by using an epoxy resin structural adhesive, then, three contact surfaces of the cross-shaped bamboo support 2 are placed in a U-shaped space surrounded by the front wood component 1-1, the left wood component 1-2 and the right wood component 1-4 and are glued by using the epoxy resin structural adhesive, finally, reinforcing fibers 3 wrapping the column body are arranged in sections along the column length direction, and are glued by using the epoxy resin structural adhesive.
The utility model discloses fiber reinforcement takes the hollow post that "ten" word bamboo supported, the advantage lies in: the utility model discloses a hollow post that area "ten" word bamboo of fibre reinforcing supported has overcome traditional wooden post mechanical properties aspect shear and compressive strength low and ductility shortcoming such as poor, and the advantage of the different material mechanical properties of each component of make full use of has higher compressive strength and shear strength, has improved the ductility of strength utilization and component.
