Description

Technical Field

[0001] The invention relates to the technical field of building reinforcement and repair, and in particular to a top support device for arch repair. Background Art

[0002] Arches are very important structural elements in historical buildings. They not only provide aesthetic decorative effects, but also have key structural functions. Arches can disperse the pressure of the upper structure and effectively transfer the weight to the supporting bodies on both sides, thereby allowing the building to span a larger space without the need for intermediate support. Traditional arches are usually built with stones and bricks. When repairing historical buildings, it is necessary to keep the original bricks as much as possible, so only the broken bricks in the arch are replaced and the whole is not dismantled and reinstalled as much as possible. For example, a reversible temporary support device for arch-type cultural relics structure disclosed in Chinese patent CN 217205566 is required to temporarily support and reinforce the ancient building of the arch structure when the arch of the ancient building is repaired. However, the support area and area of ​​the support device in the patent are limited in the range of adjustment. Arches of different sizes need to make corresponding supports, which increases the cost of arch repair. In addition, the support device in the patent has a complex support structure and cumbersome operation, which reduces the efficiency of arch repair. Summary of the invention
