Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a temporary support structure for strengthening a foundation. Background Art

[0002] In the past few decades, reinforced concrete structures have been widely used in industrial and civil buildings. With the continuous expansion of factory scale and extension of service life, the original production line can no longer meet the needs and technical transformation should be carried out. Therefore, repairing the original buildings, adding floors, adding equipment, etc. are becoming more and more common, and temporary support structures are needed during reinforcement.

[0003] The patent document with the published announcement number CN206070508U provides a device for reinforcing the foundation, which belongs to the technical field of building structure reinforcement. The utility model includes an original foundation, an inclined pile surface is arranged around the original foundation, a plurality of inclined pile holes are arranged on the inclined pile surface, and a steel cage is arranged in the inclined pile hole; a pile foundation cap is arranged on the top of the original foundation and the inclined pile surface. The inclined pile surface and the inclined pile hole are combined with the original foundation to form a tree root type pile column foundation to bear force together to meet the design requirements of the bearing capacity of the pile. It can be used not only for the foundation reinforcement of new projects, but also for the foundation underpinning of existing projects. The required construction site is small, the settlement is small, all construction operations can be carried out on the ground, the construction is convenient and there is no danger of excavation from under the foundation. No temporary support structure and a large amount of reconstruction and restoration work are required. The noise is low, and it is particularly suitable for engineering sites with narrow sites and low clearance, which is economical and environmentally friendly.

[0004] The above-mentioned device adopts a combination of inclined pile surface and inclined pile hole to form a tree root type pile column foundation with the original foundation to bear the force together, so as to meet the design requirements of the bearing capacity of the pile. However, after the above-mentioned device is installed and positioned, it is difficult to flexibly adjust the position of the supporting structure, which will make it difficult for the supporting structure to fit tightly with the side wall of the hole. In addition, the inability to adjust the position will lead to low practicality and flexibility of the support, and it cannot be used in different terrain environments. Utility Model Content
