Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel structure anchor bolt positioning device. Background Art

[0002] Anchor bolts are the foundation of steel structure construction, and their positioning accuracy directly affects the entire building. Currently, most pre-buried anchor bolts only use a positioning plate combined with a bracket embedded in the foundation or directly fix the positioning plate to the formwork. However, construction based on this method has the following problems:

[0003] (1) It requires workers to have a high level of technical skills;

[0004] The traditional pre-embedded method requires workers to have a high level of technical skills during the construction process, especially during the installation of positioning plates and the adjustment of brackets. Workers often rely on experience when operating, and the slightest carelessness may lead to positioning errors, which in turn affects the overall construction quality.

[0005] (2) The bolts will be disturbed during pouring;

[0006] During the concrete pouring process, the anchor bolts and positioning plates are easily disturbed by vibration and other operations, causing the bolt positions to shift. This shift not only affects the positioning accuracy of the bolts, but also increases the difficulty of subsequent adjustments during construction.

[0007] (3) The stent cannot be reused;

[0008] Currently, most brackets are single-use and embedded in the concrete foundation after construction, making them irreversible. While this approach ensures the bracket's securement, it also results in material waste and increased construction costs.

[0009] Based on this, it is necessary to study the steel structure anchor bolt positioning device. Utility Model Content
