Novel fixing device for prestressed corrugated pipeline

LIM HO-KYEONG / WANG WEIHUA

The invention provides a novel fixing device for a prestressed corrugated pipeline, and relates to the technical field of corrugated pipe fixing. The novel fixing device comprises a steel plate, a bent steel bar, a first hinge component, a second hinge component, a first sleeve component and a second sleeve component, wherein the bent steel bar, the first hinge component and the second hinge component are connected to the steel plate, the first sleeve component is connected to the first hinge component, and the second sleeve component is connected to the second hinge component. A channel allowing a corrugated pipe to penetrate through is formed between the bent steel bar and the steel plate. The sleeve member is configured as an annular member provided with at least one opening. The hinge component is configured to drive the opening of the sleeve component to be closed. The first hinge component and the second hinge component are arranged on the two sides of the steel plate correspondingly, so that the first sleeve component and the second sleeve component can be fixed to steel bars on the two sides of the steel plate in a sleeving mode correspondingly. The novel fixing device can ensure that the inner side is stably fixed, and the situations of welding shortage, missing, falling off and the like of the positioning rib are avoided.

本发明提供了一种预应力波纹管道的新型固定装置，涉及波纹管固定技术领域。其中，这种新型固定装置包含钢板，接合于所述钢板的弯曲钢筋、第一铰接构件和第二铰接构件、接合于所述第一铰接构件的第一套筒构件，以及接合于所述第二铰接构件的第二套筒构件。所述弯曲钢筋和所述钢板之间形成够供波纹管穿过的通道。套筒构件构造为设置有至少一个开口的环状构件。所述铰接构件构造为能够驱使所述套筒构件的开口闭合。所述第一铰接构件和所述第二铰接构件分别配置于所述钢板的两侧，以使所述第一套筒构件和所述第二套筒构件能够分别套置固定于钢板两侧的钢筋。新型固定装置可确保内侧固定稳固，避免了定位筋的缺焊、缺失和脱落等情况。
