Description

Technical Field

[0001] The utility model belongs to the technical field of building construction measurement, and specifically relates to a line-laying device for building construction measurement. Background Art

[0002] The laying-out device used for construction measurement is a combination of equipment that measures through lines. It is mainly used to accurately transfer the size, position, angle and other information on the design drawings to the actual ground at the construction site, so that construction workers can work according to these lines. By using the laying-out device, it can not only provide construction workers with clear construction reference lines to ensure that the construction is carried out according to the design drawings and that the size and structure of the building meet the design requirements, but also provide an accurate positioning basis for subsequent decoration, equipment installation, pipeline laying and other work, ensuring that these works can proceed smoothly.

[0003] Chinese patent announcement number CN220602540U discloses a wire-laying device for building measurement, which relates to the technical field of wire-laying devices, and is intended to solve the problem in the prior art that when measuring the multi-corner turning ground position, it is necessary to measure in sections, and multiple wire-collecting and wire-laying operations will be performed during the measurement process, which is troublesome to operate and very inconvenient to use. A wire spool is rotatably installed inside the housing of the device, and a measuring wire rope is arranged outside the wire spool. A placement plate is fixedly installed at the front end of the housing of the device, and a positioning member is arranged at the front end of the placement plate, and there are multiple positioning members, and the positioning member is composed of an inner folding plate, a card plate, a plug rod and a limiting block. A limiting groove is arranged inside the limiting block, and the wire spool passes through the interior of the housing of the device, and a rotating plate is fixedly installed at the front end of the wire spool, and a rotating rod is rotatably installed at the front end of the rotating plate, and a compression spring is fixedly installed inside the housing of the device, and a fixed base is fixedly installed above the compression spring.

[0004] In actual use, the utility model usually utilizes internal lines to perform measurement work. When the measurement task is completed, the lines need to be recovered into the line-releasing device. However, in the process of reeling in the lines in the existing line-releasing device, the lines are often concentrated and wound in a fixed area in the device. This phenomenon will cause uneven reeling of the lines, which will not only make the lines loose, but may also cause the lines to become entangled and knotted in subsequent use, thereby greatly reducing the use efficiency and practicality of the line-releasing device for construction measurement.
