Description

Technical Field

[0001] The utility model relates to the field of cantilever beam construction, in particular to an alignment device for welding cantilever I-beam diagonal braces. Background Art

[0002] In the field of construction, especially in the construction of high-rise buildings, the installation of cantilever beams is a crucial link. Cantilever beams not only bear part of the weight of the building, but also have a direct impact on the overall structural stability of the building.

[0003] The traditional method of installing cantilever beams is usually to first embed embedded parts on the floor slab, then use lifting equipment to lift the cantilever beam to the predetermined position, and finally perform precise alignment and welding to fix it. This method has some significant problems. First, the position accuracy of the embedded parts is extremely high. Once the embedded position deviates, the cantilever beam will not be accurately aligned, which will affect the construction quality and progress. During the lifting process, due to the large size and heavy weight of the cantilever beam, it is very easy to collide or swing, which increases the difficulty of construction and safety hazards. The traditional installation method usually requires more manual intervention, which is not only inefficient but also labor-intensive. Utility Model Content

A lower notch 302 is provided below one side of the placement groove 303 . The lower notch 302 is communicated with the placement groove 303 .

[0032] In the preferred embodiment, a lower side plate 103 is provided below the main beam 1 , and a plurality of bolt holes 104 are provided on the lower side plate 103 .

[0033] In the preferred embodiment, a retractable locking bolt 304 is further provided on one side of the placement slot 303;

[0034] A connecting shaft 401 is provided at one end of the square steel 4 , and the connecting shaft 401 is welded to the square steel 4 . Compression bolts 402 are provided at both ends of the connecting shaft 401 .

[0035] In a preferred embodiment, one end of the locking bolt 304 is threadedly connected to the connecting support plate 301 , and the other end is provided with a locking ring 305 , which is used to tightly hold the connecting shaft 401 .

[0036] In the preferred embodiment, the diameter of the connecting shaft 401 is slightly smaller than the width of the lower notch 302, and the connecting shaft 401 and the placement groove 303 can be snap-fitted;

[0037] A rubber pad 403 is provided between the clamping bolt 402 and the connecting support plate 301 . After the connecting shaft 401 is engaged with the placement groove 303 , the clamping bolt 402 is rotated to limit the rotation of the connecting shaft 401 .

[0038] In a preferred embodiment, when the locking bolt 304 rotates, the locking ring 305 moves toward the placement groove 303 , and the locking ring 305 is used to clamp the connecting shaft 401 .

[0039] A specific embodiment of an alignment device for welding cantilever I-beam diagonal braces is as follows:

[0040] On the ground, pass a connecting shaft 401 through the square steel 4, weld the connecting shaft 401 to the square steel 4, install clamping bolts 402 and rubber pads 403 at both ends of the connecting shaft 401, pass the connecting shaft 401 through the lower notch 302 and place it in the placement groove 303, keep the square steel 4 parallel to the main beam 1, turn the locking bolt 304 to make the locking ring 305 press the connecting shaft, and then turn the clamping bolt 402 to make the rubber pad 403 press the connecting support plate 301 to complete the horizontal fixation of the square steel 4;

[0041] Then, a first embedded part 6 is embedded in the first floor slab 6, a second embedded part 10 is embedded in the second floor slab 7, and a buffer plate 11 is laid out on the outer edge of the second floor slab 7. The buffer plate 11 is made of polystyrene board. Then, the alignment device is hoisted onto the first floor slab 6 by the crane 5. The main beam 1 is laid out on the first floor slab 6 and fixed to the first floor slab 6 by the expansion bolts 8. The expansion bolts 8 pass through the bolt holes 104 and are connected to the first floor slab 6. Then, the lower plate 103 is welded to the first embedded part 9 to complete the fixing of the main beam 1.

[0042] like Figure 6 As shown, the operator slowly loosens the locking of the connecting shaft 401 on the first floor slab 6, and finally makes the square steel 4 droop naturally. The bottom end of the square steel 4 abuts against the buffer plate 11. The buffer plate 11 can prevent the square steel 4 from hitting the floor slab and damaging the floor slab. At the same time, the operator on the second floor slab 7 holds the stopped square steel 4. The operator on the first floor slab 6 continues to loosen the clamping bolt 402 and does not loosen the locking bolt 304. The operator on the second floor slab 7 can push the sliding sleeve 2 to slide on the main beam 1 to adjust the angle of the square steel 4. At a suitable angle, the operator on the second floor slab 7 aligns and welds the square steel 4 with the second embedded part 10 to complete the alignment welding of the cantilever beam.

[0043] This device effectively avoids the collision of objects during lifting operations through the maneuverability of the sliding sleeve. At the same time, the slider slides left and right to find the optimal welding position between the square steel 4 and the second embedded part 10, reducing the requirements for the embedding accuracy of the embedded parts.
