Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary facilities for building construction, specifically relating to a simple tool for making lightning protection grounding jumpers. Background Technology

[0002] During the construction of lightning protection grounding systems in building projects, the lightning protection grounding bridging at the joints of structural steel reinforcement needs to be bent. However, this process is cumbersome, and there are no readily available bending tools on the market. If traditional manual bending methods are used, it is often impossible to accurately control the bending arc and angle of the lightning protection grounding bridging, resulting in a low pass rate. Furthermore, after the lightning protection grounding bridging components are bent, they need to be galvanized, but the galvanized layer is easily damaged during transportation, requiring secondary bending upon arrival at the site. This further affects work efficiency, increases construction costs, and also impacts the quality of subsequent welding. During construction, when the construction personnel have sufficient skills, the main reason why lightning protection grounding bridging cannot be formed in one go is the lack of specialized construction tools, making the process quality uncontrollable. Utility Model Content

[0003] To efficiently and quickly complete the construction of lightning protection grounding jumpers, this utility model provides a simple tool for making lightning protection grounding jumpers.

[0004] A simple tool for making lightning protection grounding jumpers is characterized by comprising a base, a fixed component, a movable rotating component, and a pressure lever handle. The base is made of two identical first galvanized steel pipes welded side by side. The fixed component includes a channel steel and a second galvanized steel pipe, the length of which is less than the diameter of the first galvanized steel pipe. The second galvanized steel pipes are horizontally and symmetrically welded to the two front sides of the top of the base, with a spacing greater than the diameter of the pressure lever handle. The back and inner sides of the channel steel are welded to the second and first galvanized steel pipes respectively, so that the channel steel is fixed vertically to the two sides of the base. The side of the channel steel with the slot facing forward has a distance between the bottom surface of the upper flange of the channel steel and the highest point of the base, which is not less than the diameter of the lightning protection grounding bridging to be bent. The movable rotating part includes a third galvanized steel pipe, a steel plate and a sleeve. The third galvanized steel pipe is set horizontally, and two steel plates are symmetrically welded to the two sides of the third galvanized steel pipe. A space larger than the diameter of the sleeve is reserved in the middle of the third galvanized steel pipe. A through hole matching the diameter of the third galvanized steel pipe is drilled horizontally at the front end of the sleeve, and the sleeve is fitted into the middle of the third galvanized steel pipe through the through hole. The length of the pressure rod handle is greater than the length of the base, and it is fitted and fixed inside the sleeve.

[0005] Furthermore, the first galvanized steel pipe is a DN150 galvanized steel pipe with a length of 1300mm, the second galvanized steel pipe is a DN15 galvanized steel pipe with a length of 160mm, and the third galvanized steel pipe is a DN15 galvanized steel pipe with a length of 240mm.

[0006] Furthermore, the channel steel is a 10# channel steel with a length of 60mm.

[0007] Furthermore, the steel plate is 6mm thick and has dimensions of 170mm*60mm.

[0008] Furthermore, the sleeve is a DN50 galvanized steel pipe with a length of 350mm, and the pressure rod handle is a DN40 galvanized steel pipe with a length of 1500mm.

[0009] Furthermore, when bending large-span lightning protection grounding bridging, a secondary pipe is also installed on the sleeve. The secondary pipe is a 350mm long DN65 galvanized steel pipe.

[0010] The beneficial effects of this invention are as follows: Through the cooperation of fixed and movable rotating components, precise control of the bending arc and angle of the lightning protection grounding bridging is achieved, solving the problems of low precision and poor pass rate in traditional manual bending. The one-piece forming design of the tool avoids damage to the galvanized layer during transportation or secondary processing, reduces the need for on-site secondary bending, improves construction efficiency, and reduces material waste. Standardized operating procedures and the use of specialized tools significantly shorten production time, reduce reliance on manual labor, and lower construction costs. Attached Figure Description

Detailed Implementation

[0016] Example 1: A simple tool for making lightning protection grounding jumpers includes a base 1, a fixed component 2, a movable rotating component 3, and a pressure rod handle 4. The base 1 is made by welding two DN150 first galvanized steel pipes 11, each 1300mm long, side by side. The fixed component 2 includes a 60mm long 10# channel steel 21 and a 160mm long DN15 second galvanized steel pipe 22. The second galvanized steel pipes 22 are horizontally and symmetrically welded to the front sides of the top of the base 1 with a spacing greater than the diameter of the pressure rod handle 4. The back and inner sides of the channel steel 21 are welded to the second galvanized steel pipe 22 and the first galvanized steel pipe 11, respectively, so that the channel steel 21 is fixed vertically on both sides of the base 1 with the slot facing forward. The distance between the bottom surface of the upper flange of the channel steel 21 and the highest point of the base 1 is not less than the diameter of the lightning protection grounding jumper 5 to be bent. The movable rotating component 3 includes a DN15 galvanized steel pipe 31 with a length of 240mm, a steel plate 32 with a thickness of 6mm and a size of 170mm*60mm, and a DN50 galvanized steel pipe sleeve 33 with a length of 350mm. The galvanized steel pipe 31 is horizontally arranged, and the upper parts of the two steel plates 32 are symmetrically welded to both sides of the galvanized steel pipe 31. A space larger than the diameter of the sleeve 33 is reserved in the middle of the galvanized steel pipe 31. A through hole matching the diameter of the galvanized steel pipe 31 is drilled horizontally at the front end of the sleeve 33, and the sleeve 33 is fitted into the middle of the galvanized steel pipe 31 through the through hole. The pressure rod handle 4 is a DN40 galvanized steel pipe with a length of 1500mm, which is fitted and fixed inside the sleeve 33.

[0017] When in use, lift the handle 4 of the pressure rod, place the lightning protection grounding jumper 5 to be bent on the machine 1, and fix the lightning protection grounding jumper 5 with the two channel steels 21. Press down the handle 4 of the pressure rod, and bend it into a uniform bending arc and angle under the opposite force of the handle 4 of the pressure rod and the machine base 1.

[0018] Example 2: When it is necessary to bend the large-span lightning protection grounding bridging 5, a 350mm long DN65 galvanized steel pipe sub-pipe 41 is fitted onto the sleeve 33 in Example 1, and the large-span lightning protection grounding bridging is bent using the same method.
