HEIGHT-ADJUSTABLE LASER LEVEL APPARATUS

Title:

HEIGHT-ADJUSTABLE LASER LEVEL APPARATUS

Document Type and Number:

WIPO Patent Application WO/2016/200034

Kind Code:

A1

Abstract:

The present invention relates to a height-adjustable laser level apparatus, comprising: a laser-emitting part which emits laser light to indicate a vertical point at a measurement point; a case part into which the laser-emitting part is inserted and coupled to protect the laser-emitting part from external impact, and to maintain the horizontality of the laser level apparatus; and a height adjustment part which is inserted into and coupled with the upper portion of the case part to adjust the height of the laser level apparatus. The laser level apparatus is coupled with the upper portion of a scaffold or a temporary material at a construction site to maintain horizontality regardless of smoothness and horizontality level of an installation surface, thereby improving accuracy of measurement. Further, the laser level apparatus is coupled without any particular support, thereby improving portability. Also, the laser level apparatus allows height to be adjusted through a simple operation by the height control part. The laser level apparatus is coupled with the upper portion, and thus does not affect worker movement or work activities such as material transfer at the time of measurement, thereby improving workability.
