Stair interlayer stair section inclined plate reinforced by newly added channel steel and construction method of stair interlayer stair section inclined plate
The invention relates to a method for reinforcing an inclined plate of a stair interlayer bench by adopting newly-added channel steel and a construction method of the inclined plate. The inclined plate comprises the newly-added channel steel, newly-added end channel steel, anchor bolts and U-shaped connecting ribs, the newly-added channel steel is arranged on the two sides of the lower portion of the inclined plate of the original stair interlayer stair flight. A-type modified epoxy resin glue is used for bonding between the newly-added channel steel and the lower skin of the inclined plate of the interlayer stair flight of the original stair on the upper portion. The newly-added channel steel is connected with an original stair interlayer stair section inclined plate on the upper portion through anchor bolts; the newly-added end part channel steel is arranged at the end part of the original stair interlayer stair flight inclined plate, and the two ends of the newly-added end part channel steel are respectively welded with the newly-added channel steel; the U-shaped connecting rib is located between the newly-added channel steel and the vertical rib of the original platform beam frame, one end of the U-shaped connecting rib is welded to the newly-added channel steel, and the other end of the U-shaped connecting rib is welded to the vertical rib of the original platform beam frame. The method is simple in construction, safe and reliable, and uniform in structure stress.
本发明涉及一种楼梯层间梯段斜板采用新增槽钢加固及其施工方法，包括新增槽钢、新增端部槽钢、锚栓、U型连接筋；所述的新增槽钢设置在原楼梯层间梯段斜板下部的两侧；所述的新增槽钢与上部的原楼梯层间梯段斜板下皮之间粘结用A类改性环氧树脂胶；所述的新增槽钢与上部的原楼梯层间梯段斜板采用锚栓连接；所述的新增端部槽钢设置在原楼梯层间梯段斜板的端部，新增端部槽钢的两端分别与新增槽钢之间采用焊接；所述的U型连接筋位于新增槽钢和原平台梁架立筋之间，U型连接筋一端与新增槽钢焊接，另一端与原平台梁架立筋焊接。本发明施工简单、安全可靠，且结构受力均匀。
