The invention relates to the technical field of regenerated composite keels for buildings, and provides a regenerated composite keel structure which comprises a wood core structure formed by stacking a plurality of layers of wood cores, and each layer of wood core is formed by splicing a plurality of short materials; the first fixing structures are arranged among the layers of wood cores and are used for fixedly connecting the layers of wood cores; the second fixing structures are laid on the top surface and the bottom surface of the wood core structure; the third fixing structure is wound and bound on the periphery of the second fixing structure and the wood core structure in the length direction of the wood core structure; the fourth fixing structure is arranged on the periphery of the third fixing structure and is in thermoplastic forming with the second fixing structure, the third fixing structure and the wood core structure. The fragile bending fracture of the keel wood core can be prevented, the ductility of the structure is improved, and the shearing strength and the bending strength of the keel structure are improved; meanwhile, contact between wood and polypropylene materials and air can be reduced, the durability of the keel structure is improved, the material turnover rate is increased, resource reutilization of waste materials is achieved, and low carbon and environment friendliness are achieved.
本发明涉及建筑用再生复合龙骨技术领域，提供一种再生复合龙骨结构，包括：木芯结构，由多层木芯层叠构成，各层木芯由多个短料拼接构成；第一固定结构，设置在各层木芯之间，将各层木芯固定连接；第二固定结构，铺设在木芯结构的顶面和底面；第三固定结构，沿着木芯结构的长度方向缠绕绑扎在第二固定结构和所述木芯结构的外围；第四固定结构，设置在第三固定结构外围，与第二固定结构、所述第三固定结构和所述木芯结构热塑成型。本发明可以防止龙骨木芯的脆性受弯断裂，增加结构延性，提高龙骨结构抗剪和抗弯强度；同时，可以减少木材和聚丙烯材料与空气接触，增加龙骨结构耐久性，提高材料周转率，实现废旧材料的资源化再利用，更加低碳环保。
