Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a drilling and welding-free adjustable reinforced concrete wall column formwork positioning method. Background Art

[0002] During construction, reinforced concrete wall column formwork is typically positioned by welding steel bars of the same width as the wall column to the bottom ends of the vertical bars in the wall column reinforcement, or by drilling holes in the ground with an electric drill and inserting short steel bars to position the wall column formwork. However, these construction methods have the following problems: welding steel bars on the vertical bars for positioning can easily damage the main bars due to welding, affecting structural safety; and drilling holes in the ground to insert short steel bars can easily penetrate pre-buried wire conduits, making it impossible to thread the wires later and difficult to clear.
