Novel connecting construction method for steel bars with straight threads through pre-located sleeves
The invention discloses a novel connecting construction method for steel bars with straight threads through pre-located sleeves. The novel connecting construction method includes the following steps that (1) lofting is carried out on steel columns and the steel bars through building information modeling (BIM) software; (2) the classification and welding positions of the sleeves are determined according to construction drawings derived from the BIM software; (3) the large chamfer ends of the sleeves face the steel columns and are symmetric to two spot welding points, the gap of 1.8-2.2mm between the sleeves and the steel columns is ensured by a tool method during spot welding, and then welding is conducted along chamfers of the sleeves for one week until specified welding bead requirementsare met; (4) the steel columns prewelded with the sleeves are transported to a site, then hoisting operation is conducted, and the bottoms of the steel columns are fixedly connected with foundation bolts pre-embedded on the site; (5) the steel bars are connected with the steel columns; and (6) after inspection and cleaning, concrete is poured. The method avoids on-site welding work, the construction speed is high and the operating time of on-site procedures is reduced.
本发明公开了一种新型预定位套筒直螺纹钢筋连接施工方法，包括以下步骤：(1)钢柱及钢筋BIM放样；(2)根据BIM软件导出的施工图纸确定套筒的分类和焊接位置；(3)将套筒的大倒角一端面对钢柱并对称点焊两点，点焊时通过工装方法保证套筒和钢柱之间留有约1.8～2.2mm的间隙；然后沿着套筒的倒角进行施焊一周至达到规定的焊缝要求；(4)将预焊有套筒的钢柱运输到现场，然后进行吊装作业，将钢柱底部与现场预埋的地脚螺栓固定连接；(5)将钢筋与钢柱进行连接；(6)检查清理后，进行混凝土浇筑。本发明避免了现场施焊工作，施工速度快，减少现场工序作业时间。
