Automatic early warning device for control pile in building survey

Abstract

The invention relates to the technical field of building measurement, and further discloses an automatic early warning device for a control pile in building survey. The device includes a shell; balls which are uniformly distributed are placed in the shell; a floating plate is placed in a sliding way through an elastic piece, a rotating plate and a flag assembly are rotationally connected in the shell, a supporting rod and an inclined plate corresponding to the rotating plate are fixedly connected to the top of an upper rotating ring, a driven plate is fixedly connected to the inner wall of a lower rotating ring, and bell assemblies which are evenly distributed are fixedly installed in an alarm bell box. When the control pile deflects, the ball rolls into a vertical section of the sliding way, and the floating plate is extruded; when the floating plate falls down, the flag assembly is driven by the rotating plate to rotate and extend outwards, so workers are reminded through a striking flag; the rotating plate rotates to drive the lower rotating ring to rotate through upward rotation, and the lower rotating ring pokes a driving lever through a top plate, so that the bell assemblies make bell sounds to remind the workers.

Description

technical field [0001] The invention relates to the technical field of building surveying, in particular to an automatic early warning device for controlling piles in building surveying. Background technique [0002] Surveying and setting out of civil buildings is the basic work and key premise in building construction. The quality of surveying and setting out closely affects the quality of building construction. The surveying and setting out should be carried out step by step according to the progress of building construction. The specific steps include initial positioning, foundation Surveying and main body surveying. Before construction, lay out multiple pile positions in the site to form a wire control network. The wire control network is the basis for setting the grid of the unit project. Generally speaking, the central and surrounding elevations of the foundation construction site should be kept at the same level. The height ensures that the central and surrounding are...

AI Technical Summary

Problems solved by technology

[0003] The control piles in civil building surveying and setting out construction should be laid on the complete bedrock, but the control piles laid in civil buildings will be affected by factors such as the settlement of the construction site and will be displaced, so the control piles should be carefully checked to ensure The correctness of the location of the control pile, and then after checking and confirming that the location of the control pile is accurate, the subsequent measurement operations can be carried out. However, there is currently no effective detection and early warning device for the control pile in civil buildings, mostly when the control pile occurs. It was discovered after a large displacement was detected, and some detection devices could not remind the staff in a timely and eye-catching manner, which brought adverse effects on the construction survey work
