Description

Technical Field

[0001] The utility model relates to a bolt fixing device, in particular to a pre-embedded bolt fixing device, belonging to the technical field of pre-embedded bolt fixing. Background Technique

[0002] Pre-embedded bolts are a kind of connecting pieces commonly used in construction and structural engineering. They are usually pre-buried in concrete before concrete pouring to provide fixed points for subsequent structures or equipment.

[0003] When arranging pre-embedded bolts, first, the pre-embedded bolts need to be fixed to the steel bars with iron wires, and then welding technology is used to weld between the pre-embedded bolts and the steel bars. Next, the concrete pouring work can be carried out. However, whether it is the process of fixing the pre-embedded bolts with iron wires or the welding process, it will inevitably affect the perpendicularity of the pre-embedded bolts, and then cause the angle deviation of the pre-embedded bolts. In this case, only reaming or special-shaped shims can be used for treatment, and even planting bolts may be required. The treatment is difficult and will seriously affect the work efficiency. During the welding process of pre-embedded bolts, the pre-embedded bolts can only be fixed with iron wires first and then welded, which results in low stability during the welding process. At present, there is a lack of a clamping and fixing device for pre-embedded bolts during the welding process on the market.

[0004] Therefore, a pre-embedded bolt fixing device is proposed. Summary of the Invention
