Tongue-and-groove threaded sleeve type diversion trench straight wall refractory concrete prefabricated part
The invention discloses a tongue-and-groove threaded sleeve type diversion trench straight wall refractory concrete prefabricated part, and belongs to the technical field of concrete prefabricated parts. The overall appearance of the prefabricated part is rectangular, the four side faces of the rectangle are provided with tenons and grooves which are connected in a tongue-and-groove mode, a threaded sleeve connecting piece and a reinforcing mesh framework are poured into the prefabricated part, and concrete used for pouring the prefabricated part is low-ablation-rate refractory concrete. The refractory concrete prefabricated part can serve as a formwork during concrete pouring of a flow guide groove straight wall structure of a rocket launching station, integrated simultaneous construction of the flow guide groove straight wall structure concrete and a refractory concrete protection layer is achieved, and it is guaranteed that the refractory concrete prefabricated part is effectively connected with the structural concrete; loosening and falling of the prefabricated part caused by rocket launching vibration are effectively prevented.
本发明公开了一种企口螺纹套筒式导流槽直墙耐火混凝土预制件，属于混凝土预制构件技术领域。预制件整体外形呈矩形，矩形的四个侧面具有企口连接的凸榫和凹槽，预制件内部浇筑有螺纹套筒连接件和钢筋网骨架，预制件浇筑所用混凝土为低烧蚀率耐火混凝土。本发明的耐火混凝土预制件能够充当火箭发射工位导流槽直墙结构混凝土浇筑时的模板，实现导流槽直墙结构混凝土和耐火混凝土防护层的一体化同时施工，并保证耐火混凝土预制件与结构混凝土有效连接，有效防止火箭发射振动导致预制件松动和脱落。
