Description

Technical Field

[0001] The utility model relates to the technical field of glue cleaning devices, in particular to a glue cleaning tool for joints of segmental beams of highway bridges. Background Art

[0002] Gluing joints is an important part of the construction process of the highway segmental beams of the bridge. When gluing, the glue material used is evenly applied to the joint surface of the beam segment. The temporary external prestressed tendons are used to apply tension to make the two beams glued together. The glue pre-applied at the joint will be squeezed out of the beam surface as the tension increases. After the elevation, axis and other indicators of the segmental beam are monitored and qualified, the extruded glue at the joint needs to be removed. Since the splicing glue has strength and is quite hard at this time, the construction workers need to squat on the beam surface with a grinder and grind it bit by bit. The construction workers bend over and squat for a long time, which makes their legs numb and their waists sore. The work is inconvenient and the work efficiency is low. At the same time, because the construction workers are close to the work surface, they are prone to inhaling more grinding dust.

[0003] Therefore, a tool for cleaning glue from the joints of segmental beams of highway bridges is proposed. Utility Model Content
