Abstract

The invention discloses a fixing method and device of a stiffened column foundation bolt anchor plate of a large raft foundation. The fixing method comprises the following steps: when foundation boltsare fixed on an angle steel bracket, pre-manufacturing a locating ring plate, and manufacturing through holes for inserting the foundation bolts in the locating ring plate; then welding the locatingring plate on the angle steel bracket according to the standard that a height from the top end of each foundation bolt to the upper surface of the locating ring plate meets a use requirement through an adjustment bolt on the foundation bolt and each foundation bolt is perpendicular to the upper surface of the locating ring plate; fixing each foundation bolt on the locating ring plate by a spot-welding manner, respectively fixing a circular stirrup on the angle steel bracket and below the locating ring plate, and welding the lower part of each foundation bolt onto the circular stirrups. According to the fixing method, the problems of inaccurate bolt locating, inconvenient fixing and the like due to deviation and lodging which are caused by concrete vibration during existing pouring of raftfoundation concrete are solved.

Description

technical field [0001] The invention relates to a method and a device for fixing anchor bolts and anchor plates of a rigid column of a large raft foundation, and belongs to the technical field of building construction. Background technique [0002] With the development of society, the functions of modern buildings tend to be diverse, and the shape and structural system of buildings tend to be complex and changeable, and tend to be three-dimensional. In response to new design concepts and the deepening of structural technology, many new structural systems have been adopted. In order to adapt to the diversification of structural systems, structural materials are developing towards diversity. The strength of concrete and steel bars is constantly increasing and strengthening. In addition, steel structures, steel-concrete hybrid structures, steel-concrete structures, and steel tube concrete structures are being widely used in the design of super high-rise structures.
