Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a construction laying-out device. Background Art

[0002] Cable laying is required during construction. In order to obtain cables according to construction requirements, construction workers will use a cable laying device to lay cables. The cable laying device mainly consists of a chassis, a cable roller rotatably mounted on the chassis, and a threading ring installed on the edge of the chassis. When in use, the worker will put the cable on the cable roller, then pass the cable end into the threading ring, and then pull the cable to complete the cable laying operation.

[0003] When multiple bundles of cables need to be laid out, workers will use a laying device that can be used to lay out multiple bundles of cables. The cable roller on the laying device is longer and occupies more space, which is inconvenient to take, use, transport and store. A laying device that can only lay out one bundle of cables cannot meet the requirements of laying out multiple bundles of cables at the same time. Multiple bundles of cables need to be laid out on multiple laying devices respectively, which is not only cumbersome to operate, but also increases the space occupied, bringing inconvenience to the construction. To this end, we propose a construction laying device. Utility Model Content
