Description

Technical Field

[0001] The utility model belongs to the technical field of street lamp construction, and particularly relates to a device for measuring the level of pre-buried steel bars in a street lamp foundation. Background Art

[0002] Streetlights are lamps that provide road lighting, broadly referring to those within the road surface illumination range of traffic lighting. Streetlights are widely used in various locations requiring illumination, and pre-buried steel bars are required during streetlight installation or renovation. Currently, the fixing methods for pre-buried components in streetlight foundations are relatively arbitrary, which can easily result in varying heights of anchor bolts. This can cause anchor bolts to deviate from the center of the foundation, anchor bolts to extend too far beyond the concrete, the upper outlet of the reserved pipe to deviate from the center of the streetlight foundation, and grounding flat steel to be omitted or placed too close to the top of the bolts, all of which affect the quality of streetlight installation. Trial installations of streetlights have exposed issues that urgently need improvement, including skewness, which has led to rework.

[0003] Currently, embedded components in streetlight foundations are typically secured by tying them to steel pipes, which are then fixed to formwork. Adjusting the formwork height allows for adjustments to the position of the embedded components. This requires frequent adjustments during construction, which is time-consuming and labor-intensive. The resulting low construction accuracy makes it impossible to accurately position the embedded components, impacting the first-pass acceptance rate for streetlight foundations and, in turn, hindering construction progress. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a device for leveling the embedded steel bars of a street lamp foundation, so as to solve the problem raised in the above-mentioned background technology that the embedded parts of the street lamp foundation are currently fixed by tying the embedded parts to steel pipes, which are fixed to templates, and the position of the embedded parts of the street lamp foundation is adjusted by adjusting the height of the template. Multiple adjustments are required during construction, which is time-consuming and labor-intensive. The construction accuracy is low, and the position of the embedded parts cannot be guaranteed to be accurate, which affects the first-time acceptance rate of the street lamp foundation and further affects the construction progress.
