Description

Technical Field

[0001] The utility model relates to the technical field of pre-buried grooves, in particular to a pre-buried groove with high strength and tensile resistance. Background Art

[0002] Embedded channels are the largest type of embedded parts. They are made by multiple hot rolling and infrared flaw detection processes, and are rolled multiple times by molds and bent into right angles. The channel is a connected or welded pillar, which is more firmly fixed in the concrete at a later time. The other side of the channel is opened, but the two sides are left with dimensions and fixed with T-bolts. T-bolts are installed in C-channel steel and have an adjustment function. They are often used in applications such as power supports, telecommunication supports, and pipeline supports and hangers. They can also be used as embedded channels for concrete pipe segments and embedded channels for building curtain walls.

[0003] The existing patent application number is CN 202221138671.0, which discloses a high-performance anti-falling embedded channel. Through the cross-lift, the rotating rod drives the L-shaped positive hook and the L-shaped inverted hook to engage with each other, which can effectively prevent the bolt and the fixing frame from loosening from the embedded channel body and ensure the stability of the bolt. However, the bolt is fixed by the L-shaped positive hook and the L-shaped inverted hook, which is inconvenient to install and position the bolt and the fixing frame, and the cross-lift is inconvenient to operate, which affects the use.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Utility Model Content
