Description

Technical Field

[0001] The utility model relates to the technical field of hoisting ear plates, in particular to a steel beam hoisting ear plate structure used for steel structure buildings. Background Art

[0002] Steel beam lifting lugs are usually made of high-strength steel with good load-bearing capacity and durability. In steel structures, lifting lugs are more often used as connecting plates or node plates, mainly used for connecting rods, and are mostly used as transition pieces to expand the connection surface.

[0003] A method for cutting off a steel structure hoisting ear plate and a cutting pad used therein disclosed in a patent application with reference announcement number CN104259578B belong to the technical field of steel structure installation and construction, and include the following contents: A. passing the cutting pad through the hoisting ear plate of the steel structure and sticking it to the surface of the steel structure, so that the hoisting ear plate is exposed from the cutting pad; B. cutting off the hoisting ear plate outside the cutting pad. The cutting pad is used to isolate the steel structure from the high temperature generated by cutting, protect the steel structure, and prevent the steel column from being deformed due to high temperature during the cutting process, thereby ensuring the quality. Moreover, the surface of the steel structure does not need to be polished after cutting, which improves the efficiency.

[0004] As shown in the above-mentioned prior art, the use of the lifting ear plate in the prior art is usually to weld one end of the lifting ear plate to the end of the steel beam, then align the two sections of the steel beam, use two connecting steel plates to clamp the adjacent lifting ear plates on the two sections of the steel beam and use bolts to connect and fix them, so as to fix the two sections of the steel beam, and then weld the steel beams at both ends. After welding, the lifting ear plate is sawed off. If such lifting ear plates are repeatedly used for repeated welding and sawing, it is very easy to cause a large number of lifting ear plates to be lost, resulting in an increase in construction costs. In addition, due to the different losses caused by sawing off, it may be difficult to align and fix such lifting ear plates when they are reused next time.

[0005] Therefore, it is necessary to provide a steel beam hoisting ear plate structure for steel structure buildings to solve the above technical problems. Utility Model Content

[0019] (III) Beneficial effects

[0020] The utility model provides a steel beam hoisting ear plate structure for steel structure buildings. Compared with the prior art, it has the following beneficial effects:

[0021] 1. The application provides a telescopic plate and a welding plate detachably mounted on one end of the telescopic plate, so that the ear plate body can be reused repeatedly. The welding plate is welded to the steel beam, and the connection between the welding plate and the steel beam is sawed after the steel beam is connected. Only the welding plate is worn out.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides two technical solutions:

[0030] Figures 1 to 3 A first embodiment is shown: a steel beam hoisting ear plate structure for a steel structure building, comprising:

[0031] The ear plate body 1 has a connecting threaded hole 3 at one end thereof for connecting with the connecting steel plate 2;

[0032] The telescopic plate 4 is slidably connected to the inner wall of the ear plate body 1;

[0033] The welding plate 5 is detachably mounted on the end of the telescopic plate 4 away from the connecting threaded hole 3;

[0034] The spacing adjustment component is installed below the ear plate body 1 and is used to adjust the spacing between the connecting threaded hole 3 and the welding plate 5 .

[0035] A first sliding groove 6 is provided on one side of the ear plate body 1 close to the welding plate 5 , and the telescopic plate 4 is slidably connected to the inner wall of the first sliding groove 6 .

[0036] A slot 7 is provided at one end of the telescopic plate 4 close to the welding plate 5, and an insert block 8 is inserted into the inner wall of the slot 7. The insert block 8 is fixed to the welding plate 5 at one end close to the welding plate 5. A first fixing screw hole 9 is provided on the insert block 8, and a second fixing screw hole 10 is provided on the slot 7 corresponding to the insert block 8. A fixing bolt 17 passes through the first fixing screw hole 9 and the second fixing screw hole 10.

[0037] A groove 11 is symmetrically formed at one end of the telescopic plate 4 close to the slot 7 . A fixing bolt 17 is located in the groove 11 and the length of the fixing bolt 17 does not exceed the thickness of the telescopic plate 4 .

[0038] This application provides a telescopic plate 4 and a welding plate 5 detachably installed on one end of the telescopic plate 4, so that the ear plate body 1 can be reused repeatedly. The welding plate 5 is welded to the steel beam, and after the steel beam is connected, the connection between the welding plate 5 and the steel beam is sawed, which only causes wear and tear on the welding plate 5. When the wear and tear of the welding plate 5 is serious, it only needs to replace the welding plate 5 to achieve repeated use of the ear plate structure.

[0039] Figure 3 to Figure 4 A second embodiment is shown, which differs from the first embodiment mainly in that:

[0040] The spacing adjustment component includes a fixed shell 12 fixed under the ear plate body 1, the inner wall of the fixed shell 12 is rotatably connected to a screw 13, the end of the screw 13 close to the connecting threaded hole 3 passes through the fixed shell 12 and is fixed with a knob 14, the outer wall of the screw 13 is threadedly connected to a slider 15, and the slider 15 is slidably connected to the inner wall of the fixed shell 12.

[0041] A second sliding groove 16 is provided below the ear plate body 1 , the outer wall of the upper end of the sliding block 15 is slidably connected to the inner wall of the second sliding groove 16 , and the top of the sliding block 15 is fixed to the bottom of the telescopic plate 4 .

[0042] This application provides a spacing adjustment component to make the ear plate structure more applicable. Since the loss generated each time the welding plate 5 is sawed and separated from the steel beam is different, when the ear plate structure is repeatedly used on the steel beam, the connecting threaded holes 3 of the welding plates 5 on the two sections of the steel beam may not be aligned. At this time, only the spacing adjustment component needs to be used to fine-tune the spacing between the welding plate 5 and the connecting threaded hole 3, which makes it easier to align the connecting threaded holes 3 of the two ear plate bodies 1.

[0043] Working principle:

[0044] Weld the end of the welding plate 5 away from the connecting threaded hole 3 to the end of the steel beam, align the two sections of the steel beam to be connected, use the connecting steel plate 2 to clamp the two ear plate bodies 1 on the same side of the two sections of the steel beam, and use bolts to penetrate the connecting steel plate 2 and the connecting threaded hole 3 one by one, so as to locate the positions of the two sections of the steel beam.

[0045] Then the welding work of the two sections of steel beams is carried out, and after the welding is completed, the welding plate 5 can be sawed off.

[0046] After repeated use, the ear plate structure will cause wear and tear during repeated welding and sawing of the welding plate 5, and the wear and tear of each welding plate 5 is different, which may easily lead to a situation where, after the steel beams are aligned during use, the connecting threaded holes 3 on the same side cannot be aligned. At this time, the knob 14 can be turned to rotate the screw 13, so that the slider 15 moves relative to the second slide groove 16 in the fixed shell 12, and the telescopic plate 4 moves relative to the first slide groove 6, so that the spacing between the connecting threaded hole 3 and the welding plate 5 changes, thereby facilitating the alignment of the connecting threaded holes 3 of the two ear plate bodies 1 on the same side.

[0047] When the welding plate 5 is seriously worn out, the welding plate 5 can be replaced, and the fixing bolt 17 can be rotated to make the fixing bolt 17 leave the first fixing screw hole 9 and the second fixing screw hole 10, and the plug block 8 can be moved out of the slot 7 to replace the welding plate 5; the plug block 8 of the new welding plate 5 is inserted into the slot 7, and the fixing bolt 17 is used again to penetrate the first fixing screw hole 9 and the second fixing screw to align and fix it, so that the fixing bolt 17 enters the groove 11 and the length of the fixing bolt 17 does not exceed the depth of the groove 11, that is, it will not affect the movement of the telescopic plate 4 in the first slide groove 6.
