Abstract

The invention provides a high strength profiled channel steel comprising a channel steel body; the channel steel body comprises an upper leg, a lower leg and a waist; the waist is connected between the upper leg and the lower leg; the upper leg and the lower leg are vertical to the waist; the channel steel body also comprises an embedded press strip which is connected to the upper leg or the lower leg; the thickness of the upper leg or the lower leg at the right side of the embedded press strip is less than that of the upper leg or the lower leg at the left side of the embedded press strip; the channel steel body also comprises a reinforced rib which is installed at the waist. By means of the high strength profiled channel steel, the door leaf production technology is simplified, the product quality and production efficiency are increased, the resistance of door leaves is enhanced and the closing reliability is increased; the high strength profiled channel steel has high promotion value.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-strength special-shaped channel steel, which is especially suitable for use on the door of protective equipment in underground protective engineering. Background technique [0002] The door leaf structure of the protective equipment door in the existing protective engineering has been designed for many years to weld the inner panel of the door leaf + embedded pressure strip + channel steel on the side of the standard channel steel to form the supporting surface for the door leaf and the door frame to fit together. One of its functions is to embed the seal to seal after compression, and the other is to form the skeleton frame of the door leaf structure. For doors with protective and airtight function requirements, this structural part must be provided. Since the door leaf is lap-welded sequentially by the embedded bead + inner panel + channel steel, not only the workload i...
