In the present embodiment, the reconstruction construction refers to a reconstruction of the surrounding road surface (ground) of the existing wooden pillar 2, which is required for excavation construction.
Specifically, the foundation reinforcement structure in this embodiment includes a prefabricated steel member including a supporting portion mainly located on the ground and an embedded portion located below the ground, and the supporting portion is connected with the embedded portion below by its members and forms an integral stress structure, thereby ensuring that sufficient supporting effect can be provided for the existing wooden column 2.
Wherein the support part in the prefabricated steel member mainly comprises a support plate 3 and a vertically arranged channel steel 1, wherein the support plate 3 is arranged at the bottom position of the existing wood structure column 2, and the surface area of the support plate is larger than the diameter of the existing wood structure column 2, namely, the support plate 3 covers the bottom surface of the existing wood structure column 2. The vertically arranged channel steel 1 is arranged at the bottom of the supporting plate 3 and forms welded connection with the supporting plate 3.
The embedded part in the prefabricated steel component comprises an embedded steel box 5, the embedded steel box 5 comprises end plates on two sides and channel steel arranged between the end plates on two sides, the channel steel is a channel steel 1 which is horizontally arranged, two ends of the channel steel 1 are respectively connected with the end plates through expansion screws 7, and the end plates on two sides are connected and fixed to form an integral structure. In this embodiment, the channel steel vertically arranged by the supporting portion and the channel steel horizontally arranged by the embedded portion form a connection, so that the supporting portion and the embedded portion of the embedded steel member are connected to form an integral structure.
As shown in fig. 1 and 2, the foundation reinforcement structure in this embodiment further includes a secondary casting concrete 9 disposed within the foundation range of the existing timber structure column 2, where the secondary casting concrete 9 can embed the embedded steel box 5 and part of the vertically arranged channel steel 1 during casting, so as to provide support for the existing timber structure column 2.
