[0021] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0022] This embodiment provides a technical solution: a recycled low-carbon wood beam for construction, such as Figure 1 As shown, it comprises: a preformed wood beam body 1, a felt cloth wrapping layer 2 and an end-sealing layer 3;

[0023] The felt cloth wrapping layer 2 is sleeved on the outside of the preformed wood beam body 1, and is used to fix the spliced ​​preformed wood beam body 1. The end sealing layer 3 is applied to both ends of the preformed wood beam body 1, and is used to improve the waterproof performance of the preformed wood beam body 1.

[0024] like Figure 2 , Figure 3 As shown, the preformed wooden beam body 1 includes multiple wooden strips 4. The thickness of a single wooden strip 4 is 14.5+ / -0.2mm, and the width is 37.8+ / -0.03mm. It is required to have no oblique strips, oblique heads, uneven ends, and no holes. The thickness of the preformed wooden beam body 1 is 58+ / -0.05mm, which is convenient for the recycling and reuse of unqualified waste wooden boards, saving energy and achieving renewable low-carbon.

[0025] like Figure 2 , Figure 3 As shown, multiple wooden strips 4 are processed by threading to form a splicing strip, and a splicing strip has 60 strips. The upper layer is threaded into the upper layer, the lower layer is threaded into the lower layer, the 10 left strips in the middle are threaded into the upper board, and the 10 right strips are threaded into the lower board, and they are threaded in sequence. The splicing strips are treated with glue dipping, and the glue dipping is made of unsaturated polyester resin, heavy calcium carbonate and additives. 100 kg of unsaturated polyester resin and 75 kg of heavy calcium carbonate are put into a seasoning barrel, and a glue mixer is used to stir evenly for 10 minutes. During the stirring process, pay attention to the temperature of the glue, which cannot exceed 50 degrees. 0.5 kg of the mixed and diluted raw materials of tert-butyl peroxide benzoyl and 1.3 kg of benzoyl peroxide are poured into the glue, and 1.5 kg of the release agent in the raw materials is added again. The power of the glue mixer is continued to be turned on, and it is stirred for 10 minutes. During the stirring process, pay attention to the temperature not being too high to avoid causing the glue to agglomerate. Prepare the dipping glue water, thread the yarn and dip the splicing strips, realize the fixed splicing between multiple wooden strips 4, and improve the quality of recycling and reuse.

[0026] like Figure 1 , Figure 2 As shown, the felt cloth wrapping layer 2 wraps the preformed wooden beam body 1 and is then cured by a hot mold. The end-sealing layer 3 is composed of a single-component polyurethane and a diluent. The ratio of a single waterproof glue is 3 kg of a single-component polyurethane and 1 kg of a diluent. Waterproof glue is applied to both ends of the preformed wooden beam body 1 to form an end-sealing layer 3, thereby improving the waterproof performance of the preformed wooden beam body 1.

[0027] When in use, the discarded wood strips 4 are recycled and processed to achieve a size thickness of 14.5+ / -0.2mm and a width of 37.8+ / -0.03mm, and the requirements for use are that there are no slanted strips, slanted heads, uneven ends, and no holes. The strips are formed through yarn threading and glue dipping to prepare a preformed wooden beam body 1, which is convenient for recycling and reprocessing of unqualified discarded wooden boards, saving energy, and achieving recycled low carbon. The preformed wooden beam body 1 is wrapped with a felt cloth wrapping layer 2 and then cured by a hot mold to shape the preformed wooden beam body 1, which is convenient for subsequent use as a wooden beam. Waterproof glue is applied to both ends of the preformed wooden beam body 1 to form an end sealing layer 3 to improve the waterproof performance of the preformed wooden beam body 1.
