Fully-fabricated anti-pulling and anti-shearing type steel-concrete composite beam
The invention discloses a fully-fabricated anti-pulling and anti-shearing section steel-concrete composite beam, which adopts an embedding form of an arrow-shaped embedding head and a necking-down-shaped embedding groove, so that the projection of a shearing head structure and the projection of the embedding groove on a plane are overlapped; the pouring materials between the arrows and the side walls of the embedded grooves are extruded, so that shearing force is prevented from being generated in the anti-pulling performance, all stress is converted into pressure on the pouring binding materials, the advantages of the pouring binding materials can be brought into full play, the good assembly structure of the patent is more excellent, and the service life of the product is prolonged. The structural advantages of the steel-concrete composite beam bridge can be fully exerted, the steel-concrete composite beam bridge can be completely, simply, efficiently and reliably assembled and installed on site, the precision requirement for on-site assembly of the composite bridge can be fully met, the overall structure and the construction technology of the composite beam are simplified, the assembly efficiency is greatly improved, meanwhile, the compression resistance characteristic of a combined material is fully utilized, and the construction cost is reduced. Negative problems of structural stability and bonding strength caused by shearing force are eliminated, the service life of the main body is prolonged, and the construction and maintenance cost is reduced.
本发明公开了一种全装配式抗拔抗剪型钢‑砼组合梁，采用箭头式嵌入头以及缩口形嵌入槽的嵌入形式，使得剪头结构与嵌入槽在平面上的投影具有重叠，在抗拔过程中，箭头与嵌入槽侧壁之间的浇注料形成挤压而避免在抗拔性能上产生剪力，从而使得所有的受力均转化为对浇筑结合料的压力，更能充分发挥浇筑结合料的优势，使前述专利较好的装配结构更为优异，能够充分发挥钢‑砼组合梁桥的结构优势，在完全、简易、高效、可靠的现场装配安装，既能充分满足组合桥现场装配的精度要求，简化组合梁整体构造及施工工艺，极大提升装配效率，同时，充分利用结合材料的抗压特性，消除剪力带来的结构稳定性和结合强度的负面问题，延长主体使用寿命，降低建设及维护成本。
