Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a traction device for laying a bendable metal conduit. Background Art

[0002] For general steel bar construction, JDG pipes can be used for pre-embedding. The pre-embedding of JDG pipes is done after the bottom reinforcement and before the upper reinforcement. However, due to the influence of the steel bar truss and the upward spiral reinforcement, it is difficult to construct the straight and oblique pipelines in the plate. The JDG pipe needs to be bent before entering the steel bar layer, and then it needs to be reversed (the second half of the same pipe cannot enter), so this will greatly increase the process time, and repeated bending can easily damage the galvanized layer, causing quality problems; therefore, truss floor decks often use bendable metal conduits for pre-embedding. However, there is a problem with the use of bendable metal conduits for pre-embedding. There is no flat surface when constructing on the truss floor deck, and the placement of the bendable metal conduit causes the pipe to be easily scratched by the steel bar during construction, and the existing laying device placed on the steel bar mesh is easily displaced during the traction process.
