Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pipe gallery brackets, and in particular relates to an I-beam welding auxiliary device. Background Art
[0002] During the construction of ground-connected walls, the design depth of a single wall generally ranges from a dozen meters to dozens of meters. Therefore, when making the ground-connected wall reinforcement cage, the I-beam on one side of the rigid joint often needs to be welded. The traditional method of connecting I-beams is to use manual auxiliary alignment (using "F"-shaped reinforcement frames). However, during the connection process, due to the large deadweight of the I-beams, the strength stability requirements of the on-site workers are high, and alignment is difficult. Misalignment is inevitable during the actual construction process (generally controlled within the requirements of the specifications). Since some projects have high requirements for the welding quality of the reinforcement cage, for example, the misalignment of the I-beam welding must be ≤2mm, which is difficult to achieve with the general manual auxiliary alignment method and cannot meet the expected standards. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an I-beam welding auxiliary device, which can effectively solve the difficulty of alignment due to the excessive weight of the cage during welding, reduce or avoid the misalignment of the I-beam welding, and improve the quality of the steel cage welding.
[0004] The purpose of the utility model is achieved through the following technical scheme. The I-beam welding auxiliary device includes a bracket frame, which is a rectangular frame. The left and right side walls of the bracket frame are provided with plug-in grooves, the notches of the plug-in grooves face the wing plate side of the I-beam, and the plug-in grooves on both sides of the bracket frame are respectively plugged into adjacent I-beam wing plates; the front and back sides of the bracket frame are both hollow structures, a jack is placed on the bottom plate of the bracket frame, and the lifting head of the jack is located below the misalignment of adjacent I-beam wing plates.
[0005] The beneficial effects of the utility model are as follows: by setting a rectangular bracket frame, setting plug-in grooves on the left and right side walls, and placing a jack in the bracket frame, auxiliary alignment of adjacent I-beam wing plates can be achieved, which can effectively solve the difficulty of alignment due to the excessive weight of the cage body during welding, reduce or avoid the misalignment of I-beam welding, and improve the quality of steel cage welding; it has the advantages of simple operation, high alignment and precision.
[0006] Preferably, the support frame includes an upper steel plate, a lower steel plate, a left steel plate and a right steel plate, and the upper steel plate and the lower steel plate are respectively fixed to the inner walls of the left steel plate and the right steel plate by welding, and the upper end surface of the upper steel plate is flush with the upper end surfaces of the left steel plate and the right steel plate, and the lower end surface of the lower steel plate is flush with the lower end surfaces of the left steel plate and the right steel plate; through the arrangement of the above-mentioned structure, while ensuring the strength of the support frame, the frame forming is more convenient and the cost is greatly reduced.
[0007] Preferably, one plug-in slot is provided on each of the left steel plate and the right steel plate, and the two plug-in slots are symmetrically distributed along the center of the bracket frame; in this way, after the plug-in slots are plugged into adjacent I-beam wing plates, the misalignment degree of the adjacent I-beam wing plates can be higher through the jack, and the flatness after alignment is better.
[0008] Preferably, the length of the plug-in slot is 2 to 5 cm greater than the width of the wing plate of the I-beam, and the height of the plug-in slot is 1 to 3 cm greater than the thickness of the wing plate of the I-beam; through the arrangement of the above-mentioned structure, the plug-in between the plug-in slot and the wing plate of the I-beam is more convenient, which also facilitates the misalignment and alignment of adjacent I-beam wing plates by the jack.
[0009] Preferably, the height of the left steel plate and the right steel plate is less than the spacing height between the upper and lower wing plates of the I-beam; after the plug-in slot is plugged into the upper wing plate of the I-beam, the entire bracket frame can be placed between the upper and lower wing plates of the I-beam, which is easy to operate.
[0010] Preferably, a lifting plate is fixed on the lifting head of the jack, so that the jack has better stability during the process of lifting and aligning the adjacent I-beam wing plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The length of the inserting groove 2 is 2 to 5 cm greater than the width of the wing plate 31 of the I-beam 3 , and the height of the inserting groove 2 is 1 to 3 cm greater than the thickness of the wing plate 31 of the I-beam 3 .
[0019] The height of the left steel plate 13 and the right steel plate 14 is smaller than the spacing height between the upper and lower wing plates of the I-beam 3 .
[0020] A jacking plate 6 is fixed on the jacking head 41 of the jack 4 .
