Precise pre-burying method for U-shaped high-strength bolts of steel guardrail
The invention discloses an accurate pre-embedding method for U-shaped high-strength bolts of a steel guardrail, which comprises the following steps of: processing two U-shaped high-strength bolts, four common nuts and a four-hole positioning steel plate into a standard pre-embedded part by using a first device; the second device is used for bearing all construction loads, and the third device and the guide steel wire rope are used for fixing the relative positions of the embedded parts in batches. The method has the following advantages that 1, welding spots can be effectively prevented from appearing at the stress part of the U-shaped high-strength bolt, the pre-embedding quality is ensured, the construction efficiency is improved, and the positioning precision is improved; the embedded part machined through the first device is good in integrity and standard in size, a positioning welding point only occurs between a common nut and a four-hole positioning steel plate, and a U-shaped high-strength bolt cannot be damaged; the third device is convenient to operate, the positions in all directions are adjusted through threads, the positioning precision can reach 2 mm, and the pre-embedding effect that a bolt is provided with one line, and a steel plate is provided with one face is easily achieved; and 4, a plurality of embedded parts can be positioned each time, and the application range is wide.
本发明公开了一种钢护栏U型高强螺栓的精准预埋方法，该方法通过使用一号装置将2根U型高强螺栓、四个普通螺帽和一块四孔定位钢板加工成标准的预埋件，使用二号装置承担全部施工荷载、使用三号装置和导向钢丝绳批量固定预埋件的相对位置。本发明具有如下优点：1、能有效避免U型高强螺栓受力部位出现焊点，保证预埋质量、提升施工效率、提高定位精度；2、使用一号装置加工的预埋件，整体性好、尺寸标准，定位焊接点只发生在普通螺帽与四孔定位钢板之间，不会伤及U型高强螺栓；3、三号装置操作方便，各方向位置均通过螺纹调节，定位精度可达到2mm，轻松达到“螺栓一条线、钢板一个面”的预埋效果；4、每次可定位多个预埋件，适用范围广。
