Description

Technical Field

[0001] The utility model relates to the technical field of construction marking, and more specifically to a building construction marking device. Background Art

[0002] Building construction refers to the production activities in the implementation stage of engineering construction, which is the construction process of various buildings. It can also be said that it is the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. At the construction site of existing building projects, construction workers need to use markers to mark the center line of the column, the elevation line and the ground position to facilitate the next step of the construction workers;

[0003] For example, a Chinese utility model patent with announcement number CN216740774U discloses a construction marker, including a marking tube, a base, a handle, an adjustment assembly and a marking sponge; the marking tube is a hollow cylindrical structure, and the handles are fixedly arranged on both sides of the outer wall of the marking tube; a storage groove is arranged in the base, the marking sponge is arranged in the storage groove, and the marking tube is fixedly arranged on the base.

[0004] Based on the above, the inventors found that the comparative document with announcement number CN216740774U adjusts the position of the marking sponge through a threaded screw and a sliding nut to achieve the storage of the marking sponge, avoids the friction between the marker and the ground when moving the marking position, and extends the service life of the marking sponge. However, the bottom of the marking device is completely open. Although the marking sponge will not rub, the dust stirred up during the movement of the marking device is easy to adhere to the marking surface of the marking sponge, thereby affecting the marking effect. Therefore, in view of this, the existing structure is studied and improved, and a construction marker is provided, in order to achieve a more practical purpose. Utility Model Content
