Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a tool for removing top support nuts. Background Technology

[0002] A top support nut is a fastener used in building support and scaffolding systems, primarily for adjusting and securing the height and position of the support rods. The top support nut adjusts the height of the top support by rotating it, ensuring a tight connection between different parts of the scaffolding. Due to varying construction conditions, the position of the top support nut on the rod also differs. For reusable top supports, the top support nut needs to be removed from the rod according to the actual situation to meet the next use requirements. In actual construction, the top support nuts are usually removed manually by rotating them. However, since there are many top supports on the construction site, manual rotation is inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide a tool for manually rotating and removing the top support nut.

[0004] This utility model is achieved through the following measures: a tool for removing a top support nut, including an electric drill, characterized in that it includes a base plate and a top plate arranged concentrically, the base plate having a through hole with an inner diameter larger than the outer diameter of the lead screw, an annular plate concentric with the through hole being provided below the base plate, a U-shaped notch with a downward opening being provided through the side wall of the annular plate, the width of the two U-shaped notches being greater than the width of the protrusions on both sides of the top support nut, and a U-shaped opening facing the protrusion being opened on the diagonal side wall of the two U-shaped notches, the opening width of the U-shaped opening being greater than the thickness of the protrusion;

[0005] The bottom plate and the top plate are connected by a support rod. A boss is fixedly provided on the top plate, and a hexagonal insertion hole is provided on the boss.

[0006] The output end of the electric drill is fixedly provided with a hexagonal rod that is inserted into the hexagonal socket, and a screw is provided on the boss by means of a threaded connection to the outer wall of the hexagonal rod.

[0007] The support rod includes an upper rod and a lower rod, and there are at least two upper rods and two lower rods. The lower rods are evenly distributed around the upper surface of the base plate, and the upper ends of all the lower rods are connected by an intermediate ring plate. The upper rods are evenly distributed around the lower surface of the top plate.

[0008] The bottom plate and the intermediate ring plate are evenly distributed with several through holes corresponding to the upper rod in the circumferential direction. The lower end of the upper rod is provided with a threaded section. The top plate is in contact with the intermediate ring plate. The lower part of the threaded section extends out of the bottom plate and is fixed by a nut.

[0009] The two ends of the threaded section are located on both sides of the intermediate ring plate, and the upper rod is fixed by nuts located on both sides of the intermediate ring plate.

[0010] The opening end of the U-shaped opening is transitioned by a rounded corner or chamfer.

[0011] A protective cylinder is concentrically arranged on the upper surface of the base plate.

[0012] The second through hole is located between two adjacent lower rods.

[0013] The length of existing top support screws generally ranges from 400mm to 700mm. In this application, the overall length of the upper and lower rods is greater than the length of the screw. When the screw is 700mm, the combined length of the upper and lower rods must be greater than 700mm. Specifically, the upper rod is longer than the lower rod to ensure that the threaded section at the lower end of the upper rod can extend beyond the base plate. The upper rod can be 450mm long, and the lower rod can be between 350mm and 400mm. The thickness of the top plate, bottom plate, and intermediate ring plate, as well as the length of the threaded section, are determined based on the actual situation.

[0014] How to use:

[0015] Before use, adjust the positions of the upper and lower rods so that the threaded sections are located on both sides of the middle ring plate and are fixed with nuts. Insert the hexagonal rod on the electric drill into the hexagonal socket and tighten it with screws.

[0016] Pass the base plate and intermediate ring plate sequentially over the lead screw. Rotate the tool to insert the U-shaped notch from above the protrusion, and continue rotating the tool to allow the protrusion to enter the U-shaped opening. Finally, start the electric drill, which will rotate the top plate, support rod, base plate, and top support nut, thereby removing the top support nut from the lead screw.

[0017] The beneficial effect of the technical solution provided by this utility model embodiment is that: with the help of a drilling machine, the top support nut can be manually rotated to facilitate unscrewing the top support nut out of the screw. Attached Figure Description
