Steel-concrete composite structure based on precoated aggregate/steel fiber reinforced concrete
The invention discloses a steel-concrete composite structure based on precoated aggregate/steel fiber concrete, which comprises a steel beam/steel box beam and a concrete plate formed by directly laying the precoated aggregate/steel fiber concrete on the steel beam/steel box beam, the precoated aggregate/steel fiber concrete comprises coarse aggregate/steel fiber, a sizing material is sprayed on the coarse aggregate/steel fiber, and the precoated aggregate/steel fiber concrete is coated on the concrete plate. After the sizing material forms an adhesive film layer which is not completely cured and has certain deformability and binding power on the surface of the coarse aggregate/steel fiber, the adhesive film layer is mixed with other raw materials of concrete and then laid on a steel beam/steel box beam, a bonding layer is arranged on the steel beam/steel box beam, and the precoated aggregate/steel fiber concrete is bonded with the bonding layer to form shear-resistant connection; the strength of a concrete interface transition area is improved, strong connection is formed between the steel beam/steel box beam and the precoated concrete, the mechanical property, durability and shear resistance of the concrete are improved, good ductility is achieved, and a shear force structure and a tension prestressed steel bar do not need to be additionally adopted.
本发明公开一种基于预涂层骨料/钢纤维混凝土的钢混组合结构，包括钢梁/钢箱梁和直接在钢梁/钢箱梁上铺设预涂层骨料/钢纤维混凝土形成的混凝土板，所述预涂层骨料/钢纤维混凝土包括粗骨料/钢纤维，在粗骨料/钢纤维上喷洒胶料，待胶料在粗骨料/钢纤维表面形成未完全固化且具有一定变形能力和粘结力的胶膜层后再与混凝土其他原材料拌合后铺设于钢梁/钢箱梁上，所述钢梁/钢箱梁上设置有粘接层，所述预涂层骨料/钢纤维混凝土与粘接层粘接形成抗剪连接；通过提高混凝土界面过渡区的强度，在钢梁/钢箱梁和预涂层混凝土之间行成强联结，提高混凝土力学性能和耐久性以及抗剪承载，具有很好的延性，无需额外采用剪力构造和张拉预应力钢筋。
