Embodiment 1

[0028] Example 1, such as figure 1 , figure 2 As shown, this embodiment provides a cold-formed thin-walled steel outsourcing fast-growing poplar high-strength beam column

[0029] 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 a straight trunk and a diameter of about 20cm are placed in a cool place. The main reason for choosing poplar with a straight trunk is that it is more convenient to process. The main reason for choosing a log 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.

[0030] Then, cut the selected fast-growing po...

Embodiment 2

[0040] Example 2, such as image 3 As shown, this embodiment provides a cold-formed thin-walled steel outsourcing fast-growing poplar high-strength beam column

[0041] Compared with Example 1, this embodiment mainly lies in that the cold-formed thin-walled steel used is different. In this embodiment, the I-shaped (H-shaped) cold-formed thin-walled steel is used. In this embodiment, by The I-shaped cold-formed thin wall is welded with two steel plates, so that a square is formed between the I-shaped cold-formed thin wall and the two steel plates. Due to the existence of the web of the I-shaped cold-formed thin wall, the overall shape Type setting, the purpose of this setting is to ensure the strength of the middle of the entire beam and column.

[0042] The method of laying is the same as that of the embodiment, one layer is 10mm thick, and the other layer is 5mm thick, but the widths are different, and finally the overall cross-section can be designed to be square.

Abstract

The invention belongs to the field of fast growing poplar application equipment, and in particular, relates to a construction process of high-strength beam columns coated with fast growing poplars outof thin-walled cold-formed steel. The construction process comprises effective steps of material selection, cutting, airing, modification, drying, dipping, welding, combination and curing. Compared with the prior art, the construction process of the high-strength beam columns coated with the fast growing poplars out of the thin-walled cold-formed steel has the advantages and beneficial effects that the thin-walled cold-formed steel is effectively matched with the fast growing poplars to form high-strength and high-toughness beam columns to meet building demands.

Description

technical field [0001] The invention belongs to the field of fast-growing poplar wood application equipment, and in particular relates to a construction process for fast-growing poplar wood high-strength beams and columns wrapped with cold-formed thin-walled steel. 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...
