Rapid line snapping tool applied to secondary structures

Abstract

The invention relates to a rapid line snapping tool applied to secondary structures. The rapid line snapping tool comprises a hollow fixed transverse rod, a hollow vertical telescopic rod and a hollow telescopic transverse rod which are communicated with each other to form an I-shaped main body, wherein two ends of the vertical telescopic rod are fixedly connected with the middle parts of the fixed transverse rod and the telescopic transverse rod; the telescopic transverse rod comprises a middle tube body and movable tube bodies; the middle tube body is located at the middle part of the telescopic transverse rod and is fixedly connected with the vertical telescopic rod; the movable tube bodies are symmetrically distributed on two sides of the middle tube body; a driving gear and two driven gears are mounted in the fixed transverse rod; the two driven gears are coaxially and fixedly connected with line rollers; the driving gear is driven to rotate by a motor; water absorption ink lines are wound on the two line rollers; two ink lines are lead out of the line rollers respectively, pass through the vertical telescopic rod and extend into the telescopic transverse rod; free ends of the ink lines are connected with ink line end connection structures at the exterior of the fixed transverse rod. The rapid line snapping tool applied to the secondary structures is simple in structure, convenient to manufacture, low in cost and high in applicability, is simple and flexible, and is capable of achieving free extension and retraction according to the length of the walls during snapping the lines.

Description

technical field [0001] The invention relates to the technical field of hand-held tools for construction engineering construction, in particular to a secondary-structure snap-wire tool. Background technique [0002] At present, before the construction of the secondary structure, the positioning lines on both sides of the masonry wall are usually popped up on the surface of the primary structure, and then the masonry construction is carried out. The traditional ink line method is to use the ink fountain ink line. Two people stand at the two ends of the ink fountain, pull out the ink line, and press the ink line on the control points of the two wall positioning lines drawn in advance at the same time, and then ink the line. After the wall positioning line on one side is played, retract the ink line, repeat the above process and then play the wall positioning line on the other side. Due to the many masonry walls in residential projects and the tight construction period, the wor...

Problems solved by technology

Due to the large number of masonry walls in residential projects and the tight construction period, the ink line workload is heavy and the task is tight, and the ink line process is cumbersome and slow, which will increase the labor intensity of the operators
