Description

Technical Field

[0001] This invention belongs to the field of steel structure welding construction technology, and particularly relates to a tool for precise lifting and auxiliary welding of indoor I-beam columns and beams, and its usage method. Background Technology

[0002] Currently, there is a lack of specialized steel beam lifting tools for welding I-beams and columns. Existing similar tools have significant limitations: First, the lifting of traditional I-beams and columns typically relies on cranes. While this method is feasible in open outdoor areas, it becomes problematic in confined spaces, especially for large steel beams, and cannot be used in small, densely packed indoor spaces. Second, movement is difficult, and stability relies heavily on additional counterweights, resulting in a high operational risk. Moving the beam requires shifting the counterweight as well, complicating the operation. Third, the tool cannot visually indicate whether the steel beam has reached the target height; traditional lifting tools have poor adjustment accuracy, requiring repeated verification with additional measuring tools, significantly increasing workload. Existing technology (CN201921140849.3) discloses a material lifting device for high-rise steel structure construction, which proposes a lifting device for I-beams; however, this device requires combination with a crane and cannot be operated indoors. To solve the above-mentioned technical problems, the present invention has specially designed a tool for precise lifting and auxiliary welding of indoor I-beam columns and beams. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a tool and method for precise lifting and auxiliary welding of indoor I-beam columns and beams. Addressing the current lack of specialized tools, the poor adaptability of existing lifting methods in confined indoor spaces, operational hazards, and low precision, this invention utilizes pre-welded I-beam columns as support points. It eliminates the need for separate counterweights, is easy to move, and occupies minimal space, making it particularly suitable for indoor environments with dense steel beams. It significantly improves operational safety. An integrated height visualization auxiliary device can intuitively and in real-time reflect the deviation between the lifting height of the steel beam and the target height, completely eliminating the tedious work of repeated measurements and achieving efficient, safe, and precise lifting, positioning, and welding assistance.

[0004] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0005] A tool for precise lifting and auxiliary welding of indoor I-beam columns and beams is disclosed. In actual construction, two sets of tools are used in conjunction at both ends of the I-beam beam. The tool includes a symmetrical main steel frame composed of two L-shaped angle steels. An adjustable height rope hanger, with its tension adjusted by a knob, is welded onto the symmetrical main steel frame. The ends of the adjustable height rope hanger extending beyond the symmetrical main steel frame have round holes. Two height reference ropes are suspended from the round holes at both ends of the adjustable height rope hanger of the two sets of tools, and are kept taut during use. The symmetrical main steel frame body, located below the adjustable height rope hanger, is inserted into the welded I-beam column. The tail of the suspension bracket is fixed to the upper middle position of the symmetrical main steel frame, and the front end of the suspension bracket has a round hole. Two I-beam clamps are snapped onto the two edges of the I-beam beam, and the two I-beam clamps are connected by a round lock. A hand-operated hoist is installed between the round lock and the round hole at the front end of the suspension bracket.

[0006] Furthermore, it also includes a symmetrical triangular support steel frame, the tail of which is welded and fixed to the symmetrical main steel frame, and the front end of which is welded and fixed to the front end of the suspension bracket.

[0007] Furthermore, when the I-beam is raised, the position is compared with that of the height reference rope to check whether the target height has been reached.

[0008] Furthermore, the lower tail end of the symmetrical main steel frame is beveled.

[0009] A method for using the aforementioned indoor I-beam column and I-beam precision lifting and auxiliary welding tools includes the following process: Insert the lower part of the symmetrical main steel frame into the I-beam column. Use the adjusting knob to control the height of the adjustable height rope device so that the height reference ropes on both sides reach the target height position of the I-beam beam. Place symmetrical I-beam clamps on both sides above the I-beam beam and install circular locks. Place the hand-operated hoist between the suspension bracket and the circular locks. Using the height reference ropes, adjust the height and level of the I-beam beam at both ends of the I-beam beam simultaneously with the hand-operated hoist. After adjustment, weld the I-beam beam to the I-beam column.

[0010] The present invention has the following beneficial effects: The device of this invention uses welded I-beam columns as support points, eliminating the need for separate counterweights, making it easy to move and occupying minimal space. It is particularly suitable for indoor environments with dense steel beams. It significantly improves operational safety. The integrated height visualization auxiliary device can intuitively and in real time reflect the deviation between the steel beam lifting height and the target height, completely eliminating the tedious work of repeated measurements and achieving efficient, safe, and accurate lifting positioning and welding assistance.

[0014] like Figure 1 , 2 As shown in Figure 3, the symmetrical main steel frame 1 is composed of two L-shaped angle steels. The upper two steel frames are connected by the adjustable height rope hanging device 4, and the lower two steel frames have a 30mm gap to allow insertion into the welded I-beam column 9.

[0015] like Figure 1 , 2 As shown in Figure 3, the tail of the suspension bracket 3 is located in the middle of the symmetrical main steel frame 1 and is fixed by welding or by bolts. The front end of the suspension bracket 3 has a circular hole with a diameter of 30mm for suspending the upper hook of the hand chain hoist 10.

[0016] like Figure 1 , 3 As shown in Figure 4, the I-beam clamps A6 and B8 have the same shape, forming a C-shape with a 20mm wide opening in the middle for securing the two sides of the I-beam beam 11. Each has a 30mm diameter hole at the top. When in use, the holes of the two clamps overlap, and a circular buckle is inserted into the hole to fix the I-beam clamps A6 and B8 together.

[0017] like Figure 1 , 3As shown, the tail of the symmetrical triangular support steel frame 2 is welded and fixed to the symmetrical main steel frame 1, and the front end of the symmetrical triangular support steel frame 2 is fixed to the front end of the suspension bracket 3, which plays an auxiliary fixing role.

[0019] like Figure 1 , 4 As shown, the adjustment knob 5 can adjust the tightness and is used to adjust the height of both ends of the adjustable height rope device 4. By adjusting the height of both ends, the height reference rope 7 is adjusted to the target height of the I-beam 11. When the I-beam 11 is raised, it can be seen intuitively through the height reference rope 7 whether the target height has been reached.

[0020] The lower end of the symmetrical main steel frame 1 is slanted to fit the ground better. When in use, the rear end abuts against the rear of the I-beam column 9, and the front end abuts against the front of the I-beam column 9, and is firmly secured by two fixing points.

[0021] Two height reference ropes 7 are respectively suspended in the round holes at both ends of the adjustable height rope holder 4 of the two sets of tools. When in use, they are taut and the height of the two height reference ropes 7 is adjusted to be the same.

[0022] The method for using the precision lifting and auxiliary welding tools for indoor I-beams described in this invention is as follows: Reference Figure 1 The lower part of the symmetrical main steel frame 1 is inserted into the I-beam column 9. The height of the adjustable height rope device 4 is controlled by the adjusting knob 5, so that the height reference ropes 7 on both sides reach the target height of the I-beam beam 11. Symmetrical I-beam clamps are placed on both sides above the I-beam beam 11, and circular locks are placed there. The hand-operated hoist 10 is placed between the suspension bracket 3 and the circular locks. The height and level of the I-beam beam 11 are adjusted simultaneously on both sides according to the height reference ropes 7. After adjustment, the I-beam beam 11 is welded to the I-beam column 9. In use, this invention involves symmetrical arrangement at both ends of the I-beam beam 11 for simultaneous lifting.
