Detailed Description
The present invention will be described in detail with reference to fig. 1 to 5.
The utility model relates to a supporting system for column underpinning. The column underpinning support system comprises a plurality of main support mechanisms 1, wherein each main support mechanism 1 comprises a jack 11, a first steel pipe 12, a steel pad plate a13, a steel pad plate b14 and a steel pad plate c15, the upper ends of two ends of each jack 11 are connected with the steel pad plate a13, and the lower ends of the two ends of each jack are connected with the steel pad plate b 14. The first steel pipe 12 is connected with a steel backing plate b14, and the other end of the first steel pipe 12 is connected with a steel backing plate c 15; in the technical scheme, the device also comprises a plurality of auxiliary supporting mechanisms 2 and a plurality of inner supporting mechanisms 3 which are matched with the main supporting mechanism 1. The utility model is applied to the column underpinning project, and the use principle of the support system is as follows: the main supporting mechanism 1 and the auxiliary supporting mechanism 2 are respectively arranged on the periphery of the post to be underpinned, the load of the post to be underpinned is unloaded, wherein the main supporting mechanism 1 is mainly jacked upwards by a jack 11 to apply a driving force, the structural deformation after the post is dismantled is reduced, meanwhile, when the defective position of the post is dismantled, the defective post 7 is divided into four areas to be dismantled, when one part is dismantled, an inner supporting mechanism 3 is arranged in the post, the load on the post can be vertically transmitted downwards through the inner support, and the phenomenon that the structural damage occurs when the stress of a beam-post node is overlarge is avoided. The support system is safe and reliable, has less damage to the original structure compared with the traditional method, and has the advantages of convenient construction, low construction cost and the like.
