Bridge construction joint cutting device with controllable joint cutting depth
The invention provides a joint-cutting depth-controllable bridge construction joint-cutting device, which belongs to the technical field of bridge construction, and comprises a joint-cutting machine whole body and advancing wheels arranged below the joint-cutting machine whole body, and further comprises a joint-cutting disc, and when the joint-cutting machine whole body advances along a bridge concrete surface, joint cutting is performed on a concrete layer through clockwise rotation of the joint-cutting disc. According to the invention, through the joint-cutting design and the layered design of the joint-cutting with the large upper part and the small lower part, the joint-cutting on the surface layer of the bridge floor can be relatively large, so that the requirement of a bridge concrete surface layer, especially an arch-shaped bridge floor, on large expansion and contraction quantity generated during temperature change can be met, and the problems of surface layer cracking, deformation and the like caused by overlarge stress during temperature change of the bridge are avoided; meanwhile, the bottom kerf is narrow, the width of the kerf deep layer can be effectively reduced while the requirement for small stress change of the bridge concrete deep layer is met, the integrity and safety of the bridge are guaranteed, and the overall service life of the bridge is prolonged.
本发明提供了切缝深度可控的桥梁施工切缝装置，属于桥梁施工技术领域，包括切缝机整体和设置于切缝机整体下方的行进轮，还包括：切缝盘，在切缝机整体沿桥梁混凝土面行进时，通过切缝盘的顺时针转动，对混凝土层进行切缝。该发明，通过此种切缝设计，切缝上大下小呈分层式设计，可以使桥面表层切缝较大，可以满足桥梁混凝土表层尤其是拱形桥面，在温度变化时产生的大伸缩量需求，避免桥梁在温度变化时应力过大导致的表层龟裂和变形等问题，同时底部切缝较窄，在满足桥梁混凝土深层较小应力变化的同时，可以有效减少切缝深层的宽度，保证桥梁的整体性和安全性，提升了桥梁整体使用寿命。
