Description

Technical Field

[0001] This utility model belongs to the field of conduit fixing technology, and more specifically, it relates to a device for fixing the spacing of electrical box conduits. Background Technology

[0002] In the field of building construction, pre-embedded conduits are a key component of electrical wiring and pipe laying. Their stability and integrity are crucial for subsequent electrical installation and pipe laying. However, in actual construction, pre-embedded conduits often shift due to external forces or compression during concrete pouring, or even become blocked or damaged due to debris entering the openings, seriously affecting construction quality and subsequent maintenance.

[0003] Traditional methods of fixing conduit often involve directly securing the embedded conduit to the reinforcing steel bars using wire or cable ties. While simple, this method suffers from inconsistent fixation, allowing the conduit to easily shift during construction and lacking effective protection measures for any openings. This is particularly problematic for fixing conduit in electrical boxes, where precise control of conduit spacing is crucial for ensuring the accuracy and safety of subsequent electrical installations; traditional methods fall short in this regard.
