Embedded drainage pipe fitting
The invention relates to an embedded drainage pipe fitting, and mainly aims to solve the problems that when an existing embedded flange connector drainage pipe fitting is embedded, a hole needs to be formed in a template in advance, so that the template is difficult to reuse, the workload is increased, or flange bolts need to be reserved in bolt holes in advance, so that the template is prone to rust, and a pipeline is difficult to mount and dismount. According to the technical scheme, the embedded drainage pipe fitting is composed of an upper connector and a lower connector which are both flange bellmouths, bolt connecting holes with planes opened outwards are formed in the outer walls of the bellmouths, the width of plane openings of the bolt connecting holes is smaller than the length, and the bolt connecting holes are vertically divided into two layers and are provided with sealing plates with a concrete adjacent layer. After bolt fixing heads extend into the bolt connecting holes from the narrower layer, the bolts are rotated to enable the fixing heads to be clamped in the wider layer, a rubber ring and a flange gland are arranged in the pipeline in a sleeved mode, and a nut is tightened to extrude the rubber ring to form sealing connection. According to the embedded drainage pipe fitting, the drainage pipe fitting of the flange connector can be directly embedded, holes do not need to be formed in the template, bolts do not need to be reserved or threads do not need to be machined in advance, and the pipeline is convenient and rapid to mount and dismount.
本发明涉及一种预埋式排水管件，主要目的是解决现有预埋式法兰接口排水管件在预埋时，需要在模板上提前开孔洞造成模板难以重复利用、增加工作量，或需要将法兰螺栓提前预留在螺栓孔内造成容易生锈、安装拆卸管道困难的问题。其技术方案为：由上、下接口构成，均为法兰承口，承口外壁上均有平面向外开的螺栓连接孔，螺栓连接孔的平面开口宽度小于长度，竖向分两层，与混凝土邻近层有封闭板，螺栓固定头从更窄的一层伸入螺栓连接孔后转动螺栓使固定头卡在更宽的一层，将胶圈和法兰压盖套入管道，拧紧螺母挤压胶圈形成密封连接。本发明能实现法兰接口的排水管件直接预埋，无需在模板开孔洞，无需提前预留螺栓或加工螺牙，管道安装、拆卸方便快速。
