Method for fixing cantilevered profile steel with high-strength bolts
The invention discloses a method for fixing cantilevered profile steel with high-strength bolts, and belongs to the technical field of cantilever system construction in construction engineering. The process flow is as follows: various components are processed and prefabricated according to design; two holes with a diameter of 22mm are reserved on a side beam of a cantilevered floor structure of abuilding, then the high-strength bolts with a diameter of 20mm are used for passing through the reserved holes to fix the cantilevered profile steel, and both sides are screwed with nuts and gaskets;and the end of the cantilevered profile steel is suspended and diagonally pulled, an oblique tie rod is made of round steel with a diameter of 20mm, and the upper part of the diagonal tie rod is fixedat the position of the side beam of the upper floor of the cantilevered floor to ensure the force. The advantages are as follows: the problems of high leakage risk in a later period, damage to a shear wall and reinforced steel bars of a concealed column and the like of the upper suspension diagonally pulled cantilevered profile steel and lower diagonally braced cantilevered profile steel are solved well; and the construction is safe, the production is simple, the cost is saved, and the use is easy.
一种高强螺栓固定悬挑型钢的方法，属于建筑工程的悬挑体系施工技术领域。工艺流程：按照设计加工预制各种构件；在楼栋悬挑层结构边梁预留2个直径22mm孔洞，后采用直径20mm高强螺栓穿过预留孔固定悬挑型钢，两边用螺帽、垫片拧固；悬挑型钢端部上悬斜拉，斜拉杆采用直径20mm圆钢，斜拉上部固定在悬挑层上一层边梁位置，保证受力。优点在于，很好的解决了上悬斜拉式和下斜撑式悬挑型钢后期渗漏风险大、破坏剪力墙、暗柱受力钢筋等问题；并且，施工安全、制作简单、节约了成本、易使用。
