Fabricated cement-based combined formwork column
The invention discloses a fabricated cement-based combined formwork column which comprises a combined formwork (10), a reinforcement cage (20), an opposite-pull screw rod (30) and internal cast-in-place concrete (40), and is characterized in that the combined formwork (10) is formed by combining a cover plate (2) with a reserved hole channel (1) and a side plate (3) through a steel bar planting rod (4) to form a formwork-removal-free formwork of the internal cast-in-place concrete (40); the embedded steel bar rod (4) is anchored in a communicating hole channel formed by the reserved hole channels (1) of the cover plate (2) and the side plates (3) through structural adhesive (5); a positioning pipe (6) is arranged on the reinforcement cage (20) in the orthogonal direction of the cross section, and the length of the positioning pipe is consistent with the inner clearance size of the combined formwork (10) in the corresponding direction; and the opposite-pull screw rod (30) penetrates through the positioning pipe (6) and the combined formwork (10) and applies pre-tightening force by tightening the fastening nuts (7) at the two ends, so that the reinforcement cage (20) and the combined formwork (10) are combined. Compared with the prior art, the combined formwork column has the advantages that the single formwork plate is prefabricated, production is simple, efficiency is high, and cost is low; in the splicing process, an embedded connecting piece with the high requirement for positioning precision does not need to be arranged, pretightening force is applied through the opposite-pulling screw rods, rapid assembling of the combined formwork and the reinforcement cage is achieved, and efficiency is high. The method has a good application prospect in the field of formwork columns.
本发明公开了：一种装配式水泥基组合模壳柱，包括组合模壳（10）、钢筋笼（20）、对拉螺杆（30）和内部现浇混凝土（40），其特征在于：组合模壳（10）由带预留孔道（1）的盖板（2）和侧板（3）通过植筋杆（4）组合起来，形成内部现浇混凝土（40）的免拆模壳；所述植筋杆（4）通过结构胶（5）锚固在盖板（2）和侧板（3）的预留孔道（1）所形成的连通孔道中；所述钢筋笼（20）沿横截面的正交方向设置定位管（6），其长度与组合模壳（10）对应方向上的内净空尺寸一致；所述对拉螺杆（30）贯穿定位管（6）和组合模壳（10），并通过拧紧两端的紧固螺母（7）施加预紧力，将钢筋笼（20）和组合模壳（10）结合起来。相比于已有技术，本发明的组合模壳柱，其模壳板单块预制，生产简单、效率高、成本低；拼装时，无需设置定位精度要求高的预埋连接件，且采用对拉螺杆施加预紧力，实现了组合模壳与钢筋笼的快速装配，效率高。本发明在模壳柱领域具有良好的应用前景。
