Problems solved by technology

However, due to its low mechanical properties, poor corrosion resistance and large instability, fast-growing poplar has not been used in building structures.
At present, there are few studies on how to apply fast-growing poplar wood to building structural components through carbon fiber modification, and to broaden its application range

Embodiment 1

[0031] Example 1, such as figure 1 As shown, the present embodiment provides a construction technique of carbon fiber modified fast-growing poplar, including the following effective steps:

[0032] First of all, material selection, considering that the modified fast-growing poplar wood provided in this embodiment is used in construction, so in this implementation, 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 placement in a cool place is mainly to avoid exposure to the sun, which will cause cracking of the poplar and affect its strength.

Embodiment 2

[0048] Embodiment 2, this embodiment provides a kind of construction technique of carbon fiber modified fast-growing poplar

[0049] Such as figure 2 As shown, the difference between this embodiment and the construction technology of carbon fiber modified fast-growing poplar provided by Example 1 lies in the setting of the groove 2 and the protrusion 3, compared with the groove 2 provided by Example 1 along the poplar The long side of the board 1 is arranged at intervals, and the structure is staggered along the short side direction. The grooves 2 provided in this embodiment are set through the board 1, that is, the grooves 2 are only arranged at intervals along the long side of the poplar board 1, so that The benefit mainly lies in the convenience of processing. Since columns, beams, panels, and walls of different sizes are required in the construction process, the construction technology of the carbon fiber modified fast-growing poplar wood provided in Example 1 needs to be...

Abstract

The invention belongs to the technical field of fast-growing board modification and particularly relates to a carbon fiber modified fast-growing poplar construction process. The process includes effective steps of a, material selection; b, cutting; c, deep processing; d, airing; e, thermal modification; f, drying; g, cutting; h, carbon cloth glue preparation; i, impregnation; j, combination; k, maintenance. Compared with the prior art, the carbon fiber modified fast-growing poplar construction process has advantages that by modification treatment of fast-growing poplar through carbon fibers, carbon cloth glue and a series of processes including processing, adhering, maintaining, pre-pressing, after-treatment and the like, mechanical properties such as compressive strength, elasticity modulus, deformation rate and quake resistance of the fast-growing poplar are changed to meet utilization requirements of construction structural components (columns, beams, boards and walls).

Description

technical field [0001] The invention belongs to the technical field of fast-growing board modification, and relates to the modification of fast-growing poplar, in particular to a construction process of carbon fiber modified fast-growing poplar. 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 fast-growing trees have low density, soft w...
