Embodiment 1

[0035] Example 1, such as figure 1 , figure 2 As shown, the present embodiment provides a construction technique of steel plate outsourcing carbon fiber modified fast-growing poplar, including the following effective steps:

[0036] First of all, material selection, considering that the modified fast-growing poplar wood provided in this embodiment is used in construction, so in this embodiment, the selection of materials also plays a vital role in the strength of the finished product in the later stage. First, select The fast-growing poplar has a straight trunk and a log diameter of about 20cm, and put it in a cool place. The choice of poplar with a straight trunk is mainly because it is more convenient to process the poplar with a straight trunk. The log with a diameter of about 20cm is selected. Mainly considering the needs of the construction of this embodiment, the purpose of placing it in a cool place is mainly to avoid exposure to the sun, which will cause cracking of ...

Embodiment 2

[0056] Embodiment 2, this embodiment provides a kind of construction technology of steel plate outsourcing carbon fiber modified fast-growing poplar

[0057] Such as Figure 4 As shown, the difference between this embodiment and the construction process of the steel plate outsourcing carbon fiber modified fast-growing poplar wood provided by Example 1 lies in the setting of the groove 21 and the protrusion 22 of the plate, compared with the groove provided by Example 1 21 are arranged at intervals along the long side of the poplar board 2 and staggered along the short side direction. The grooves 21 provided in this embodiment are set through the board 2, that is, the grooves 21 are only spaced along the long side of the poplar board 2 set up.

Embodiment 3

[0061] Embodiment 3, this embodiment provides a kind of construction technology of steel plate outsourcing carbon fiber modified fast-growing poplar

[0062] Such as Figure 5 As shown, the main difference between the construction technology of the steel plate outsourcing carbon fiber modified fast-growing poplar wood provided by this embodiment and embodiment 1 and embodiment 2 is the setting of the wrapping mode of the steel plate, compared with the steel plate of embodiment 1 and embodiment 2 1. The entire package is wrapped outside the combined plate 2. The method provided in this embodiment is to wrap at intervals, so that the steel plate 1 forms square circles and is evenly spaced outside the plate 2, thereby achieving the purpose of improving the overall strength. This embodiment is similar to Compared with the structural design of Embodiment 1 and Embodiment 2, the amount of steel plate used is greatly reduced. Regarding the layout of the plate grooves, it can be the s...

Abstract

The invention belongs to the technical field of fast-growing wood modification and especially relates to a construction technology for steel plate coated carbon fiber modified fast-growing poplar. The construction technology comprises the following steps: a) selecting materials; b) cutting; c) deeply processing; d) airing; e) thermally modifying; f) drying; g) shearing; h) preparing a structural adhesive; i) dipping; j) combining; k) wrapping; l) maintaining; m) cutting. Compared with the prior art, the construction technology for steel plate coated carbon fiber modified fast-growing poplar, provided by the invention, has the advantages and positive effects that the methods for processing, bonding, maintaining, pre-pressing and post-processing the fast-growing wood through the carbon fiber, steel plate, structural adhesive and a series of construction technologies are adopted for modifying, so that the mechanical properties, such as compressive strength, elasticity modulus, deformation rate and anti-seismic property, of the fast-growing poplar can be changed and the fast-growing poplar can meet the use requirement of the architectural structure components (columns, beams, plates and walls).

Description

technical field [0001] The invention belongs to the technical field of modification of fast-growing boards, and relates to the modification of fast-growing poplar, in particular to a construction technique for modifying fast-growing poplar with steel plates covered with carbon fibers. Background technique [0002] As an important production resource in social and economic construction, wood and wooden materials are not only widely used in various fields in daily life, but also widely used in industrial fields such as transportation, construction and aerospace. With the increasing shortage of forest resources worldwide, especially the sharp decline in the amount of precious wood, a large number of fast-growing trees have been widely planted in recent years. Fast-growing trees have the advantages of short production time and high yield, but due to their short growth period, for example, the general artificial fast-growing poplar takes 5 to 6 years to become useful, so most fas...
