Steel truss vestibule lower chord reinforcing method
The invention relates to the technical field of industrial building steel structure reinforcement, and discloses a steel truss vestibule lower chord reinforcement method. The reinforcing method comprises the following steps: welding channel steel on a part of lower chord members between two adjacent cross beams, and buckling notches of the channel steel below the lower chord members; and a connecting plate is welded below the end part of each channel steel, and the connecting plates and the web plates of the cross beams are reinforced through angle steel. According to the reinforcing method, installation is convenient, operation is easy, normal production of the belt conveyor in the vestibule is not affected, complex construction processes such as chiseling are not involved, butt welding does not exist, an original steel member is not damaged, it can be guaranteed that an original lower chord and a newly-added member are jointly stressed, the bending resistance of the lower chord is remarkably improved, and the service life of the lower chord is prolonged. The problem that the bearing capacity of the steel truss is insufficient due to corrosion, overload and the like is effectively solved, and high economic benefits and social benefits are achieved.
本发明涉及工业建筑钢结构加固技术领域，公开了一种钢桁架通廊下弦杆加固方法。该加固方法包括以下步骤：在相邻的两根横梁之间的部分下弦杆上焊接槽钢，并使得槽钢的槽口扣在下弦杆的下方；在每个槽钢端部的下方分别焊接连接板，将连接板与横梁的腹板之间通过角钢加固。本发明提供的加固方法安装方便、操作简单，不影响通廊内皮带机正常生产，且不涉及剔凿等施工较复杂工艺，不存在对接焊且不对原有钢构件造成损伤，能够保证原下弦杆与新增构件共同受力，显著提高下弦杆抗弯能力，有效解决钢桁架因腐蚀、超载等原因所引起的承载力不足问题，具有较高的经济效益及社会效益。
