Setting-out device for ceiling roof

Abstract

The invention provides a setting-out device for a ceiling roof. The setting-out device comprises an ink fountain. A coil is arranged in the ink fountain. A central rotary shaft is arranged in the center of the coil. A rotary handle is externally arranged at one end of the central rotary shaft. One end of the coil is fixed to the center of a rod through a flexible wire pipe, a pulley, a wire pressing ring, a line snapping rope and a groove in the top end of the rod. The flexible wire pipe is a transparent plastic pipe. The pulley is made of hard wood. The wire pressing ring is made of galvanized round steel. A main rope of the line snapping rope is made of elastic rubber materials. The periphery of an operating rod is made of hard round wood. Compared with a former construction method, the setting-out device is simple and convenient to use, practical and reasonable in structure, the defects of conventional operation are overcome, the construction period is shortened, equipment investment is reduced, the cost is reduced, construction is arranged reasonably through the change of the objective environment, measuring and setting-out as well as installation operation can be implemented independently, and thus construction delay is avoided.

Description

technical field

[0001] The invention belongs to the technical field of measurement, and relates to a ceiling wire pay-off device. Background technique

[0002] At present, in the construction process of construction projects, in order to make reasonable use of space, there are a lot of equipment and pipelines arranged on the ceiling. Personnel working on the side construction or setting up the operation platform use the ink fountain to set out the line, and even use the feeling to locate, but there are the following problems: 1. The environment for using the laser vertical instrument must be in a certain degree of darkness, otherwise it cannot be seen or seen clearly, so it is used during the day Extremely inconvenient. 2. Since the construction of the ceiling requires a lot of time, and there are many operating points and a wide area, it is necessary to increase the number of operating instrument personnel to follow up the measurement, resulting in sufficient equipment and...
