Foundation bolt pre-embedding positioning device and construction method thereof

CHEN XINBIAO

The invention provides a foundation bolt pre-embedding positioning device and a construction method thereof, relates to the technical field of electric power iron towers and street lamp poles, and solves the technical problems that a foundation bolt pre-embedding construction method is high in working difficulty, a foundation bolt fixing mode is unreliable, and the perpendicularity of a foundation bolt cannot be guaranteed. The device comprises a first positioning support and a second positioning support, the first positioning support and the second positioning support are #-shaped frames formed by intersecting at least two longitudinal rods and at least two transverse rods, and the tail ends of the longitudinal rods protrude out of the outermost intersection points of the longitudinal rods and the transverse rods and extend outwards, and limiting structures for the foundation bolts in at least two directions are formed at the intersection points located on the outermost sides of the positioning supports, and the first positioning support and the second positioning support are stacked up and down in a crossed mode so as to position each foundation bolt in four directions. After positioning is conducted through the first positioning support and the second positioning support, the position size of the whole set of foundation bolts is accurate, and the overall stability is good.

本发明提供了一种地脚螺栓预埋定位装置及其施工方法，涉及电力铁塔、路灯灯杆技术领域，解决了地脚螺栓预埋施工方法工作难度大，对地脚螺栓的固定方式不可靠，无法保证地脚螺栓的垂直度的技术问题。该装置包括第一定位支架和第二定位支架，第一定位支架和第二定位支架是由至少两个纵向杆和至少两个横向杆相互交叉形成的井字型架，纵向杆的末端突出于其与横向杆的最外侧交叉点向外延伸，并在位于定位支架最外侧的交叉点处形成对地脚螺栓在至少两个方向上的限位结构，第一定位支架和第二定位支架呈十字交叉上下叠放以对每个地脚螺栓在四个方向上进行定位。通过第一定位支架和第二定位支架进行定位后，整组地脚螺栓位置尺寸准确，整体性稳定性较好。
