Embodiment 1
[0048] Example 1: refer to the attached Figure 1-15 A profiled steel reinforcement device for a pedestrian passage frame is shown, comprising a profiled steel frame and a passage reinforcement structure, wherein the passage reinforcement structure is symmetrically arranged on the outer side of the profiled steel frame, and acts with the inner wall of the pedestrian passage to reinforce the pedestrian passage;
[0049] The profiled steel frame includes a side frame profiled steel 1, a top profiled steel 2 and a bottom profiled steel. The side profiled steel 1 is symmetrically arranged between the top profiled steel 2 and the bottom profiled steel, and is connected to the top profiled steel 2 and the bottom profiled steel through the adjusting mechanism 5. The bottom frame is connected with profiled steel to form a profiled steel frame;
[0050] The channel reinforcement structure is a reinforcement steel plate 3, the reinforcement steel plate 3 is connected with the profiled s...
Embodiment 2
[0065] Embodiment 2: Different from Embodiment 1, in order to further connect the frame steel reinforcement device of the pedestrian passage to the pedestrian passage and the backside structure of the passage, to enhance the integrity of the reinforcement structure and the solid, and prevent the surrounding and pedestrian passage structures Settlement, the grouting anchor rod 8 sequentially includes a tail end anchor section, a standard anchor section 81 and a front end anchor section from the outside to the inside. It is connected by a screw 82 and is closed at the front end of the front end anchor section, and a tapered head is provided at the front end of the front end anchor section.
[0066] Preferably, the tail end anchor section, the anchor section 81 and the front end anchor section all include a grouting cylinder 84 , a retaining wall sleeve 85 and an anchoring connecting rod 86 , wherein the retaining wall sleeve 85 is arranged on the grouting cylinder 84 . The outer...
