Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] see Figure 1-Figure 6 , a cross-laminated wood board strengthened by a nanocomposite material, comprising a first board 1, a second board 2, and a structural adhesive layer 3; the first board 1 is soaked in a nanocomposite solution, and ultrasonic waves are used to make The board after the composite material is evenly dispersed into the microstructure of the wood; the first board 1 and the second board 2 are stacked alternately and glued by the structural adhesive layer 3, and the top layer and the bottom layer are the second board 2; the first board 1 and the second board The wood grain direction of plate 2 is perpendicular to each other, combining figure 1 with Figure 4 As can be seen.

[0030] In this embodiment, the second board 2 in the cross-laminated wood board has one more layer than the first board 1, and the total number o...

Abstract

The invention relates to an orthogonal glued wood board reinforced by a nanocomposite and a manufacture method thereof. The orthogonal glued wood board reinforced by the nanocomposite comprises firstboards, second boards and structure glue layers, wherein each first board is formed by performing soaking treatment on a wood through a nanocomposite solution and using ultrasonic waves for uniformlydispersing the nanocomposite into the microstructure of the wood, the first boards and the second boards are alternately overlapped and bonded through the structure glue layers, the top layer and thebottom layer are two layers of the second boards, and grain directions of each first board and each second board are perpendicular to each other. The orthogonal glued wood board reinforced by the nanocomposite fully uses a connection function of the nanocomposite on the microstructure of the wood, significantly improves roll shearing intensity and cross grain tensile strength of the wood, is simple in structure, convenient to construct and convenient to popularize to engineering, substantially improves bending strength and shearing resistance of a wood floor, and is beneficial to popularization of a wood building.

Description

technical field [0001] The invention relates to a cross-glued wood structure, in particular to a cross-glued wood board strengthened by a nanocomposite material. Background technique [0002] At present, the consumption of building materials in our country has produced a serious load on the ecological environment and social development. Since the 1970s, my country's building types have been dominated by reinforced concrete structures, masonry structures and steel structures. The production and use of related building materials consume a large amount of non-renewable resources such as iron ore, limestone and land, and aggravate the greenhouse effect. Therefore, my country urgently needs to develop a new type of building structure system that is low-carbon, energy-saving and environmentally friendly. [0003] Cross-laminated timber components have many advantages such as low-carbon environmental protection, easy construction, high lateral rigidity, good fire resistance and d...
