Abstract
Description
Technical Field

[0002] During the construction process, embedding large-diameter anchor bolts in the concrete foundation structure is the focus and difficulty of civil construction. The control of the axis deviation and verticality of the anchor bolts is the key to the entire construction process, which directly affects the overall quality of the subsequent steel columns. The traditional method of fixing embedded bolts is to fix the chassis at the bottom of the anchor bolts. At the same time, in order to ensure the verticality of the anchor bolts, flanges with anchor bolt holes need to be set at equal intervals above the chassis. However, this method requires multiple flanges to be set on the anchor bolts, which is complicated to operate. The flange can only ensure the fixed spacing between multiple anchor bolts, but cannot ensure the overall stability of the anchor bolts. The anchor bolts are prone to displacement as a whole during concrete pouring, causing safety hazards. Utility Model Content
