Non-dismantling formwork column
The invention discloses a non-dismantling formwork column which comprises a combined formwork (100), a shaped reinforcement cage (200) and a detachable opposite-pulling piece (300), and is characterized in that a combined formwork shell (100) is formed by combining a cover plate (1) and a side plate (2) of a pre-embedded light cushion block (20) through an L-shaped connecting strip (3) and a structural adhesive (4); the cover plate (1) and the side plates (2) are fiber-reinforced high-performance cement-based prefabricated plates, the outer side faces (5) of the fiber-reinforced high-performance cement-based prefabricated plates are smooth surfaces, and the inner side faces (6) of the fiber-reinforced high-performance cement-based prefabricated plates are rough surfaces with outwards-extending steel fibers (7) and grooves (8). Positioning pipes (9) are arranged on the shaped reinforcement cage (200) in the orthogonal direction of the cross section, and the positions of the positioning pipes (9) are in one-to-one correspondence with the positions of the embedded light cushion blocks (20) in the prefabricated formwork (100); the detachable opposite-pulling piece (300) penetrates through the embedded light cushion block (20) and the positioning pipe (9), and pre-tightening force is exerted by screwing fastening nuts (11) at the two ends of the detachable opposite-pulling piece (300), so that the shaped reinforcement cage (200) and the combined formwork (100) are combined. Compared with the prior art, the disassembly-free formwork column has the advantages that the combined formworks are combined in the mode that prefabrication is conducted firstly and then assembly is conducted, production is easy, and assembly is efficient. And a rough surface with overhanging steel fibers and grooves is formed on the inner surface of the template in a high-pressure water jet washing manner, so that the process is efficient, simple and convenient, and the bonding force between the prefabricated template and internal cast-in-place concrete can be remarkably improved. The method has a good application prospect in prefabricated buildings.
本发明公开了：一种免拆模板柱，包括组合模板（100）、定型钢筋笼（200）、可拆卸式对拉件（300），其特征在于：组合模壳（100）由预埋轻质垫块（20）的盖板（1）和侧板（2）通过L型连接条（3）和结构胶粘剂（4）组合起来；所述盖板（1）与侧板（2）为纤维增强高性能水泥基预制板，其外侧面（5）为光洁表面，而内侧面（6）是带有外伸钢纤维（7）与沟槽（8）的粗糙面；所述定型钢筋笼（200）沿横截面的正交方向设置定位管（9），其位置与预制模板（100）中的预埋轻质垫块（20）一一对应；所述可拆卸式对拉件（300）贯穿预埋轻质垫块（20）和定位管（9），并通过拧紧两端的紧固螺母（11）施加预紧力，将定型钢筋笼（200）和组合模壳（100）结合起来。相比于已有技术，本发明的免拆模板柱，其组合模板采用先预制、后拼装的方式进行组合，具有生产简单、装配高效等优势。且通过高压水射流冲刷的方式，在模板的内表面形成带有外伸钢纤维和沟槽的粗糙面，工艺高效简便，能显著提升预制模板与内部现浇混凝土的粘结力。本发明在装配式建筑中具有良好的应用前景。
