Description
Technical Field
The utility model relates to the field of foundation pit engineering in underground space development, in particular to a flexible connection device for a reverse construction steel pipe column and a steel reinforcement cage.
Background
The large-scale engineering construction in China generates a large amount of underground space engineering, and the construction land, the sensitive engineering environment and the various construction period requirements are tensed, so that the design and construction of foundation pit engineering face more complex requirements, and the reverse construction method technology provides a new technical means for meeting the requirements. In the reverse construction method, the permanent steel upright post is adopted as a vertical supporting structure of the beam slab with the reverse horizontal structure, and is used as a main structure post in the later stage, if the deviation of the position or the verticality is overlarge in the earlier stage construction, the position or the verticality is difficult to treat, so that the requirement of the permanent steel upright post on the construction precision is high.
Because the use of reverse construction method steel stand, cast-in-place pile pore-forming depth is darker under the steel stand, in order to guarantee the smooth laying of steel reinforcement cage, generally with steel stand and steel reinforcement cage at drill way connection fixed back, wholly descend to downthehole.
The conventional connection mode is to bend the steel bars, and weld the two ends of the steel bars on the steel upright posts and the steel bar cages respectively to form rigid connection. The connecting method has higher efficiency for the steel upright post with shallow buried depth, because the steel upright post with shallow buried depth is mostly a temporary vertical support post, the requirements on the center point and the verticality of the steel upright post are relatively lower, the steel upright post only has a temporary supporting function, and the steel upright post needs to be removed in the later construction of the main body structure.
However, the construction precision requirement of the permanent steel upright post is high, and the steel upright post needs to be adjusted in real time in the construction process no matter in the construction of a 'rear insertion method' and a 'front installation method'. If a rigid connection mode is adopted between the steel upright post and the steel reinforcement cage, once the deviation of the position or the perpendicularity of the steel upright post is too large, the deviation of the perpendicularity of the hole can not be adjusted at all, and the errors of the vertical direction and the horizontal direction in the hole when the steel reinforcement cage is lowered to the bottom of the hole can directly influence the precision of the permanent steel upright post.
Therefore, a flexible connecting device is needed, so that the steel reinforcement cage and the steel upright post can be jointly lowered after being connected, and the elevation, the center point and the verticality of the steel upright post can be adjusted, so that the steel upright post is not influenced by the steel reinforcement cage.
