Problems solved by technology
Since the support plate + inclined flat steel + the inclined flat steel in the support plate is obliquely welded with the standard angle steel, there are the following disadvantages: first, manual positioning is required, and the workload increases; second, deformation will occur during welding, which will affect the straightness ; Again, manual welding must be used due to the inability to use automatic welding. There are many welding procedures and inaccurate positioning, and even many shortcomings and defects such as virtual welding and false welding, which cause the leak between the oblique flat steel and the angle steel, and then affect product quality
However, the special-shaped angle steel for civil air defense disclosed in the above-mentioned patent has the following defects: 1. The oblique flat steel marked 4 is not easy to process, and it is easy to break when connected by an arc, which affects the overall sealing and protection effect of the door frame; 2. The angle steel marked 1 The strength of the body is low; 3. The oblique flat steel marked 4 and the ribs marked 2 limit the size of the contact surface between the door frame and the door leaf, resulting in uneven stress on the door leaf and unreliable airtight performance

The invention provides a specially-shaped integrated steel angle special for a protective equipment door frame. The specially-shaped integrated steel angle comprises a steel angle body, a rectangular bearing plate, a trapezoid bearing plate and an adhesive tape groove, wherein the steel angle body is provided with two perpendicular sides, the rectangular bearing plate and the trapezoid bearing plate are arranged outside one side of the steel angle body, the adhesive tape groove is formed between the rectangular bearing plate and trapezoid bearing plate and the outside of the corresponding side of the steel angle body, and the steel angle body, the rectangular bearing plate and the trapezoid bearing plate are integrally formed. The specially-shaped integrated steel angle is high in strength and rigidity and is wholly sealed.
Description
technical field [0001] The invention relates to the field of building materials, in particular to a special-shaped integral angle steel for a protective equipment door frame, which is especially suitable for use on the door frame of an underground protective engineering protective equipment door. Background technique [0002] The door frame of the protective equipment door in the existing protection project follows the design that has been used for many years, that is, welding the support plate + oblique flat steel + support plate on one side of the standard angle steel to form the rubber strip fixing groove and the support surface of the door leaf. The first function of the standard angle steel is to embed and fix the seal, and the second function is to bear the pressure of the door leaf. For the door frame with protection and airtight function requirements, the standard angle steel is a load-bearing part. Since the support plate + inclined flat steel + the inclined flat st...
