Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a guide device for threading spiral ribbed steel bars in concrete. Background Technology

[0002] For some large buildings, in order to increase the strength of the concrete structure, it is often necessary to use spiral rib steel bars to anchor the concrete. During the concrete pouring process, a certain number of cable-threading pipes are pre-embedded in a specific direction. Then, multiple steel bars are threaded into the cable-threading pipes using a steel bar threading machine. Finally, anchors are used at the opening of the cable-threading pipes to tighten the steel bars.

[0003] Traditional threading guidance methods mostly involve passing a guide rope through a threading tube and fixing it to the rebar. Then, by pulling the other end of the guide rope, the rebar is pulled along by the guide rope to guide the threading. However, this single-pulling guidance method lacks an auxiliary threading guidance device, which makes the connection point between the guide rope and the rebar prone to breakage due to the pulling, requiring secondary guidance. At the same time, pulling in one direction is relatively laborious, resulting in low threading efficiency. Therefore, it has the drawback of not having an auxiliary threading guidance device, thus failing to meet the needs of customers.

[0004] Therefore, those skilled in the art have provided a concrete spiral ribbed steel bar threading guide device to solve the problems mentioned in the background art. Utility Model Content
