Device for controlling thickness of steel bar protective layer of bridge pier column and construction method of device
The invention provides a device for controlling the thickness of a steel bar protective layer of a bridge pier column and a construction method of the device, and relates to the technical field of bridge construction.The device comprises a pier column body, an adjusting frame arranged outside the pier column body in a sleeving mode and a plurality of supporting rods arranged below the adjusting frame; a plurality of inner formworks close to the pier column body are arranged on the adjusting frame, a plurality of outer formworks away from the pier column body are arranged on the adjusting frame in a sliding mode, the inner formworks and the outer formworks are arranged in the circumferential direction of the pier column body, a steel bar protection layer is formed between the inner formworks and the outer formworks, and an adjusting assembly for adjusting all the outer formworks to slide synchronously is arranged on the adjusting frame; the method comprises the steps of cleaning a construction range, installing the adjusting frame, adjusting the thickness of the protective layer, binding reinforcing steel bars and pouring the protective layer. The bound reinforcing steel bars and the pier column body are supported through the inner formwork, movement of the inner formwork and the outer formwork in the reinforcing steel bar binding process is reduced, then the thickness of a reinforcing steel bar protection layer is precisely controlled, and therefore the advantage of improving the thickness control precision of the pier column reinforcing steel bar protection layer is achieved.
本申请提供一种控制桥梁墩柱钢筋保护层厚度的装置及其施工方法，涉及桥梁施工技术领域，装置包括墩柱本体、套设于的墩柱本体外的调节架、设置于调节架下方的多个支撑杆，调节架上设置有多个靠近墩柱本体的内模板、滑动设置有多个远离墩柱本体的外模板，内模板和外模板均围绕墩柱本体周向设置，内模板和外模板之间形成有钢筋保护层，调节架上设有调节全部外模板同步滑动的调节组件；方法包括：清理施工范围、安装调节架、调节保护层厚度、钢筋绑扎、保护层浇筑。本申请通过内模板供绑扎的钢筋和墩柱本体支撑，减少钢筋绑扎过程内模板和外模板的移动，进而精准控制钢筋保护层的厚度，从而具有提高墩柱钢筋保护层厚度控制精度的优点。
