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 steel plate modification, and to broaden its application range

Embodiment 1

[0032] Example 1, such as figure 1 , figure 2 As shown, the present embodiment provides a construction technique of steel plate modified fast-growing poplar, including the following effective steps:

[0033] 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 later finished product. First, select the fast-growing poplar Poplar logs with straight trunks and a diameter of about 20cm are placed in a cool place. The main reason for choosing poplars with straight trunks is that they are more convenient to process. The main reason for choosing logs with a diameter of about 20cm Considering the construction needs of this embodiment, the main purpose of placing it in a cool place is to avoid exposure to the sun, which will cause cracking of the poplar and affect its strength.

[0034] Then, the...

Embodiment 2

[0051] Embodiment 2, this embodiment provides a kind of construction technique of steel plate modified fast-growing poplar

[0052] like image 3 As shown, the difference between this embodiment and the construction process of the steel plate modified fast-growing poplar wood provided in Example 1 is the setting of the groove 2, which is provided at intervals along the long side of the poplar wood plate provided by Example 1. The short-side direction is staggered. 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 direction of the poplar board 1. The advantage of this arrangement is mainly to facilitate processing. In the construction process, columns, beams, boards, and walls of different sizes are required. The construction technology of the steel plate modified fast-growing poplar wood provided by Embodiment 1 needs to be processed according to the needs of the site, and the techno...

Abstract

The invention belongs to the technical field of fast-growing wood modification and especially relates to a construction technology for steel plate 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) maintaining. Compared with the prior art, the construction technology for steel plate 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 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 fast-growing wood modification, and relates to the modification of fast-growing poplar, in particular to a construction technique for modifying fast-growing poplar with a steel plate. 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 densit...
