Laser marking positioning device and building snapping line marking positioning method

Abstract

The invention provides a laser marking positioning device and a building snapping line marking positioning method. The device comprises a main support frame, a first wavelength laser and at least two second wavelength lasers, wherein the main support frame is provided with two opposite sides; at least two support feet are arranged at one side; the main support frame extending direction is defined to be the first direction; the first wavelength laser is arranged at the other side of the main support frame relative to the support feet, and outputs a first laser line along the first direction; the at least two wavelength lasers are arranged at the other side of the main support frame relative to the support feet, and output second laser lines; the second laser lines and the first laser line are intersected to form at least two focal points. Through the device, the distance from the wall is determined; at least two laser line focal points are generated, so that the line snapping by an inking pot is performed at the focal points of the laser lines. The distance from the snapping line position to the all can be accurately measured; the laser marking positioning device can be conveniently, fast and accurately used in various kinds of application with line snapping requirements.

Description

technical field [0001] The present invention relates to the technical field of building elastic thread, in particular to a marking positioning device for elastic thread and a marking positioning method for elastic thread. Background technique [0002] Thread snapping is a method of construction work. The specific operation method is: use a thread dipped in ink, two people each take one end and bounce it on the ground or wall. The function is to determine the horizontal line or vertical line, or as a reference line for building walls. Among them, the ground wire refers to the tool line used to mark the clear height of the room and the depth of the bay in the process of building household acceptance. The ground wire is generally used in residential building construction. [0003] As a basic link in building construction, snapping wire has very high requirements for its accuracy in construction, because it will determine the success or failure of the next process. It is worth...

Problems solved by technology

[0004] In view of the above situation, the present invention provides a laser marking positioning device and a construction spring line marking positioning method thereof. By setting a fixed-length leg on the laser marking positioning device, it is used to abut against the wall, so as to accurately measure the spring The distance from the wall of the line position; in addition, by setting the first wavelength laser and at least two second wavelength lasers, the intersection of the laser line output by the first wavelength laser and the laser line output by the at least two second wavelength lasers generates at least two focal points , to solve the technical problems of insufficient mark position accuracy in the existing manual spring line marking and unfavorable for identification in dark places, so that the laser marking positioning device of the present invention can be conveniently, quickly and accurately used in various ground line operations that require
