Reinforced concrete composite T beam adopting prefabricated U-shaped ECC permanent formwork
The invention discloses a reinforced concrete composite T beam adopting a prefabricated U-shaped ECC permanent formwork, and belongs to the field of structural engineering. The reinforced concrete composite T beam comprises the prefabricated U-shaped ECC permanent formwork, a reinforcement cage and concrete, wherein the reinforcement cage is of a T-shaped structure, the vertical part of the reinforcement cage is hoisted in the prefabricated U-shaped ECC permanent formwork, and the concrete is poured in the reinforcement cage. According to the reinforced concrete composite T beam, the U-shaped permanent formwork with the uneven inner surface is prefabricated by adopting an ECC material, the reinforcement cage is directly installed in the prefabricated ECC permanent formwork on a construction site, the concrete is poured to form the T beam, and the problem that a traditional reinforced concrete T beam is difficult to transport and hoist is solved; and meanwhile, the advantages that the ECC material is high in tensile strength and excellent in crack control performance are fully utilized, the problem that the traditional reinforced concrete T beam is prone to cracking is solved, and the cracking load, the bearing capacity, the ductility and the energy dissipation capacity of the structure are improved.
本发明公开了一种采用预制U形ECC永久模板的钢筋混凝土复合T梁，属于结构工程领域领域，包括预制U形ECC永久模板、钢筋笼和混凝土，钢筋笼呈T形结构，钢筋笼的竖直部分吊装在所述预制U形ECC永久模板中，混凝土浇筑在钢筋笼中。本发明采用ECC材料预制内表面凸凹不平的U形永久模板，在施工现场直接在预制ECC永久模板内安装钢筋笼，浇筑混凝土形成T形梁，解决传统钢筋混凝土T梁运输与吊装难的问题；同时充分利用ECC材料抗拉强度高、控制裂缝性能优异的优点，解决传统钢筋混凝土T梁易开裂的问题，提高结构的开裂荷载、承载力、延性和耗能能力。
