Auxiliary positioning device and positioning method of foundation bolts

Abstract

The invention discloses an auxiliary positioning device. The device is used for positioning foundation bolts on a reinforced concrete foundation platform. The device comprises a vertical supporting rod, a first axis positioning rod arranged on the vertical supporting rod and a first radius positioning rod; the axis which is emergent from the radial direction of the center point of the ring defined by the foundation bolts can be crossed with the first axis positioning rod arranged in the tangent direction of the ring; the first radius positioning rod is arranged on the supporting rod or the first axis positioning rod and is arranged in the radial direction of the ring, the track of the ring can be crossed with the first radius positioning rod. When the foundation bolts are positioned through the auxiliary positioning device, the axis point and the radius point can be precisely positioned on the bolts, through the axis point and the radius point, the reference point is positioned, positioning of the mounting position of the foundation bolts can be achieved, in the process, due to the fact that the measuring distance between the axis point and the radius point and the reference point is obviously reduced, the measuring error is greatly reduced, positioning precision of the foundation bolts can be obviously improved, and the construction quality is ensured.

Description

technical field [0001] The present invention relates to the technical field of construction tools, in particular to an auxiliary positioning device for positioning anchor bolts, and also relates to an anchor bolt positioning method suitable for the above auxiliary positioning device. Background technique [0002] The anchor bolt is an indispensable fastening connector embedded in the reinforced concrete foundation to connect with the upper steel structure frame. , Fix the upper steel structure frame on the reinforced concrete foundation, so as to stabilize the upper steel structure, so that it will not be damaged by the influence of equipment operation and natural weather. [0003] At present, there are more and more applications of reinforced concrete foundation caps (that is, multiple concrete foundations in a circular arrangement, and anchor bolts need to be installed on each concrete foundation) in industrial buildings, such as sintered ring coolers, steel chimneys, etc....

AI Technical Summary

Problems solved by technology

The commonly used anchor bolt installation method is the method of projecting points from the center point of the reinforced concrete foundation cap to the anchor bolt installation point to determine the anchor bolt installation position. Due to the distance between the ring foundation center point and the anchor bolt installation point Larger, so the error of the data measured by the measuring tool is also relatively large, and in the calibration process, the cumulative error of multiple measurements will also increase the positioning error of the installation position of the anchor bolts, which seriously affects the radian deviation of the upper steel structure , stress and stability, so that the construction quality cannot be guaranteed

[0004] In addition, for the normal implementation of the above positioning method, it is also necessary to ensure that the central point of the reinforced concrete foundation cap and the installation point of the external anchor bolts maintain a clear view (that is, there are no obstacles between the two points), so that the construction of the positioning of the anchor bolts will be greatly improved. come a big limit
