Description

Technical Field

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

[0002] During the construction process, it is necessary to excavate a foundation pit. Before excavating the foundation pit, a thin rope needs to be laid on the ground, and then white lime is sprinkled along the thin rope to provide instructions for excavating the foundation pit. The thin rope needs to be supported by a rod at the bend. A pointed head is processed at one end of the rod. The rod is knocked into the ground with a hammer to limit the position of the rod. In the process of pulling out the rod, due to the lack of suitable tools, manpower is required to pull out the rod and recycle the rod. For the rod with a deeper insertion depth, the resistance to pulling out is relatively large, and the labor intensity of manual pulling out is high. Therefore, it is necessary to design a construction layout device that can conveniently pull out the rod from the ground. Utility Model Content

[0005] Furthermore, the middle position of the upper surface of the top plate is recessed downward to form a plug hole, a pin rod is inserted in the plug hole, and a protective plate is connected and fixed to the upper end of the pin rod.

[0006] Furthermore, a rubber head is adhered to the lower end of the pin rod, and the rubber head is inserted into the socket, and the outer diameter of the rubber head is the same as the inner diameter of the socket.

[0007] Furthermore, a detachable column rod is installed on one side of the bottom block, and a disc is connected and fixed to one end of the column rod away from the bottom block.

[0008] Furthermore, the outer surface of one end of the column away from the disc is processed with external threads, and the side of the bottom block facing the column is provided with a threaded hole, and one end of the column processed with external threads is threadedly connected in the threaded hole.

[0009] Furthermore, a pipe sleeve is provided on one side of the top block, a plurality of connecting columns are connected and fixed to the outer surface of the pipe sleeve, an end of the connecting column away from the pipe sleeve is connected and fixed to the top block, and the pipe sleeve is provided on the insertion rod and connected and fixed to the insertion rod.

[0011] Beneficial effects of the utility model:

[0012] 1. Insert the pin on the protective plate into the socket. At this time, the rubber head fits against the inner wall of the socket, which prevents the pin from escaping from the socket at will. The hammer hits the protective plate, and the protective plate prevents the hammer from directly contacting the top plate, which protects the top plate. The thin rope is wound in the annular groove, and the rod and top plate inserted in the ground support the thin rope, which is convenient for the line-releasing operation.

[0013] 2. When inserting the plug rod into the ground, make the plug rod pass through the vertical hole on the bottom plate. When the plug rod needs to be pulled out, insert the plug strip into the plug slot to complete the plug connection between the bottom block and the bottom plate, so that the lower inclined surface is parallel to the upper inclined surface, and then use a hammer to knock the bottom block to make the bottom block push the top block upward, and the top block drives the plug rod to move upward, so that the plug rod is pulled out of the ground by hammering. Compared with the method of manually holding the plug rod and pulling it upward, it saves time and effort and can conveniently pull the plug rod out of the ground. BRIEF DESCRIPTION OF THE DRAWINGS
