Description

Technical Field

[0001] The utility model relates to the technical field of I-beams, in particular to a welding-free I-beam reinforcement device. Background Art

[0002] I-beams, also known as steel beams, are long strips of steel with an I-shaped cross section. I-beams have high load-bearing capacity, strong stability, and the ability to withstand pressure and tension, and are often used as load-bearing and supporting components. In the construction field, I-beams are usually used as load-bearing components such as beams and columns to support the weight of the entire building, playing an important load-bearing role.

[0003] I-beam reinforcement is a measure taken to improve the load-bearing capacity and stability of I-beams. By adding materials to the flange part of the I-beam, its bending resistance is enhanced. At present, I-beams on the market are basically reinforced by welding, but for some factories where fire cannot be used, it is difficult to perform welding reinforcement, so another reinforcement method is urgently needed.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5The non-welded I-beam reinforcement device comprises an I-beam body 1, an upper mounting frame 3 and a lower mounting frame 31 are fixedly arranged below the upper and lower flanges of the I-beam body 1, and an upper steel plate 4 and a lower steel plate 41 are respectively assembled in the upper mounting frame 3 and the lower mounting frame 31 by means of steel glue and high-strength bolts 2. A plurality of reinforcing blocks 5 are fixedly arranged on the outer sides of the upper steel plate 4 and the lower steel plate 41, and a reinforcing cavity 51 is adapted to be opened on the upper mounting frame 3 and the lower mounting frame 31 corresponding to the reinforcing blocks 5. It is worth noting that the structures of the upper mounting frame 3 and the lower mounting frame 31 as well as the upper steel plate 4 and the lower steel plate 41 are the same, and they are only different in size.

[0021] Among them, two upper mounting frames 3 form a group, and the two upper mounting frames 3 are respectively fixedly mounted on both sides of the bottom of the upper flange of the I-beam body 1, and the upper steel plates 4 are all mounted in the upper mounting frames 3. By setting the steel glue in the upper mounting frames 3, the upper steel plates 4 can be fixed.

[0022] The lower mounting frame 31 is fixedly mounted on the bottom of the lower flange of the I-beam body 1, and the lower steel plate 41 is mounted in the lower mounting frame 31. By setting the steel adhesive in the lower mounting frame 31, the lower steel plate 41 can be fixed.

[0023] Among them, multiple through holes 21 are vertically penetrated on the upper and lower flanges of the I-beam body 1, and threaded holes 22 are vertically penetrated and opened on the upper steel plate 4 and the lower steel plate 41 corresponding to the through holes 21. High-strength bolts 2 are inserted downward from the top of the through holes 21, and the high-strength bolts 2 are successively passed through the through holes 21 and the threaded holes 22 and then fixed by nuts 23. By setting the high-strength bolts 2, the fixing strength between the upper steel plate 4 and the lower steel plate 41 can be strengthened.

[0024] Among them, the four sides of the top of the upper steel plate 4 and the lower steel plate 41 are all provided with installation grooves, and the reinforcing block 5 is fixedly arranged in the installation grooves. The interior of the reinforcing block 5 is provided with a connecting cavity 52, and the connecting cavity 52 is "Z-shaped". Through the setting of the connecting cavity 52 inside the reinforcing block 5, the steel adhesive can be circulated when the upper steel plate 4 and the lower steel plate 41 are installed, thereby ensuring that the steel adhesive is evenly adhered to the upper steel plate 4 and the lower steel plate 41.

[0025] In this embodiment, when the user needs to reinforce the flange of the I-beam body 1, the user only needs to invert the I-beam body 1 so that the side of the flange with the upper mounting frame 3 and the lower mounting frame 31 faces upward. Then, the steel glue is evenly applied to the upper mounting frame 3 and the lower mounting frame 31, and the upper steel plate 4 and the lower steel plate 41 are pressed and placed in the upper mounting frame 3 and the lower mounting frame 31. When the upper steel plate 4 and the lower steel plate 41 enter the upper mounting frame 3 and the lower mounting frame 31, the steel glue in the upper mounting frame 3 and the lower mounting frame 31 will be squeezed outward due to the entry of the upper steel plate 4 and the lower steel plate 41, and the outward squeezed steel glue will pass through the connecting cavity 52 in the reinforcing block 5, so that the steel glue can be squeezed onto the side wall of the mounting groove opened on the upper steel plate 4 and the lower steel plate 41 after passing through the connecting cavity 52, thereby improving the stability of the upper steel plate 4 and the lower steel plate 41 fixed by the steel glue.

[0026] Furthermore, by providing the reinforcing block 5 and the reinforcing cavity 51, the contact area between the upper steel plate 4 and the lower steel plate 41 and the upper mounting frame 3 and the lower mounting frame 31 can be increased when they are fixed by means of steel glue, thereby improving the stability of the upper steel plate 4 and the lower steel plate 41 being fixed by means of steel glue.

[0027] Furthermore, after the adhesive on the upper steel plate 4 and the lower steel plate 41 is fixed and formed, the I-beam body 1 can be flipped over and reset again, so that the side with the upper mounting frame 3 and the lower mounting frame 31 on the flange faces downward. Then, the user inserts the high-strength bolt 2 into the through hole 21 and the threaded hole 22, and fixes them with the nut 23, so as to realize the reinforcement of the flange of the I-beam body 1.

[0028] In the utility model, an upper mounting frame 3 and a lower mounting frame 31 are fixedly arranged below the upper and lower flanges of the I-beam body 1, respectively, and the upper steel plate 4 and the lower steel plate 41 can be fixed in the upper mounting frame 3 and the lower mounting frame 31 respectively by setting steel glue and high-strength bolts 2. This method of reinforcing the flange of the I-beam body 1 does not require welding, so it can be reinforced in a factory building where fire is not allowed.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
