Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to a reinforcement device using a steel I-beam. Background Art

[0002] A slab culvert refers to a building whose tunnel body is composed of a cover plate, a cap, a culvert platform, a foundation and an expansion joint. The fill height is 1 to 8 meters, and can even reach 12 meters. The construction technology is relatively simple and the flood discharge capacity is large. During the construction of the slab culvert, steel I-beams are required to support the formwork. Generally, the diameter of the slab culvert is relatively limited, so the strength and rigidity of the steel I-beams used for support must be good. Existing steel I-beams need to be reinforced with reinforcement devices during use.

[0003] For example, in the Chinese utility model with announcement number CN216517061U and name of a maintenance and reinforcement device for a steel structure I-beam, a patch plate is placed in the two abdominal cavities of the I-beam body, the patch plate is put into the abdominal cavity of the I-beam body and close to the abdominal plate, the reinforcement plate is inserted into the inside of the pressing groove, and the threaded bolt is rotated to press the movable plate inward through the threaded tube connected by the thread. The contact surfaces of the movable plate and the slope block are both inclined surfaces. Therefore, when the movable plate moves inward, it will press the two slope blocks to move apart, so that the two slope blocks are close to the inner sides of the upper and lower wing plates of the I-beam body, thereby enhancing the bearing capacity between the upper and lower wing plates of the two I-beam bodies. Although the above-mentioned prior art can enhance the bearing capacity between the upper and lower wing plates of the I-beam body, the bearing area is limited, and multiple of the above-mentioned reinforcement devices are required to enhance the strength and rigidity of a relatively long I-beam beam, which is inconvenient to install. In order to increase the area of ​​one reinforcement, a reinforcement device using a steel I-beam is now needed. Utility Model Content

[0004] The purpose of the utility model is to provide a steel I-beam reinforcement device with a simple structure and reasonable design in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A reinforcement device using a steel I-beam comprises an I-beam body, wherein a plurality of reinforcement mechanisms are arranged in the abdominal cavities on both sides of the I-beam body, wherein the reinforcement mechanisms comprise a sliding base arranged at the bottom of the abdominal cavity of the I-beam body and a guide cylinder fixedly arranged on the upper side of the sliding base, wherein support plates cooperating with the top of the abdominal cavity of the I-beam body are arranged on both sides of the guide cylinder for lifting and lowering, a lifting assembly for driving the lifting and lowering of the support plates on both sides is arranged on the inner side of the guide cylinder, and an adjusting assembly for adjusting the distance between the two support plates is arranged on the lifting assembly.

[0007] As a further optimization scheme of the utility model, the lifting assembly includes a screw rod rotatably arranged on the inner side of the guide cylinder and a threaded sleeve arranged on the outer side of the screw rod and sliding with the inner side of the guide cylinder. A driving nut is fixedly arranged on the screw rod, and the outer side of the threaded sleeve is connected to the support plate through a rotating assembly.

[0008] As a further optimization solution of the utility model, the rotating assembly includes a mounting base fixedly arranged on the outside of the threaded sleeve, and one end of the mounting base is rotatably provided with a diagonal brace connected to the bottom of the support plate.

[0009] As a further optimization scheme of the utility model, the adjustment assembly includes a second threaded rod rotatably arranged on the outside of the threaded sleeve and a first threaded rod rotatably arranged on the diagonal support, and the threaded sleeve at the interface between the first threaded rod and the second threaded rod is provided with an adjustment screw sleeve.

[0010] As a further optimization solution of the utility model, limiting grooves cooperating with the mounting base and the adjustment assembly are provided on both sides of the guide cylinder.

[0011] As a further optimization scheme of the utility model, lower reinforcement plates slidably connected to the sliding base are fitted on the bottom of the abdominal cavity on both sides of the I-beam body, and upper reinforcement plates cooperating with the support plate are fitted on the top of the abdominal cavity on both sides of the I-beam body. A rolling groove is provided on the upper side of the lower reinforcement plate, and a ball bearing movably cooperating with the rolling groove is provided on the bottom of the sliding base.

[0012] The beneficial effects of the utility model are as follows: in the utility model, by rotating the driving nut, the screw rod is driven to rotate, so that the threaded sleeve can move up and down under the restriction of the limit groove and the mounting base, thereby driving the lifting and lowering of the diagonal support on one side of the mounting base, pushing the support plate at the upper end of the diagonal support to rise, so that the support plate and the upper reinforcement plate are tightly fitted, which is used to support the web of the I-beam and to reinforce the I-beam, and by rotating the adjusting screw sleeve, the first threaded rod and the second threaded rod are moved away from each other, and then the diagonal support is pushed to rotate around the mounting base by the first threaded rod, so that the distance between the two support plates is adjusted, and the support area can be adjusted, and the support reinforcement area can be increased by a reinforcement mechanism, thereby improving the reinforcement effect, without using a lot of reinforcement mechanisms, and improving the installation efficiency.

When in use, by rotating the driving nut 6, the screw rod 4 can be driven to rotate, so that the threaded sleeve 5 can move up and down under the action of the limit groove 13 and the mounting base 15, driving the diagonal brace 7 and the support plate 8 at the upper end of the diagonal brace 7 to move up and down, so that the support plate 8 and the upper reinforcement plate 9 on the inner side of the abdominal cavity of the I-beam body 1 can fit closely, thereby reinforcing the abdominal cavity part of the I-beam body 1, improving the strength and rigidity of the I-beam body 1, so that the I-beam body 1 can support heavier formwork, which is convenient for supporting in the limited space of the cover culvert construction.

[0021] like Figure 2As shown, the bottom of the belly cavity on both sides of the I-beam body 1 is fitted with a lower reinforcing plate 10 that is slidably connected to the sliding base 2, and the top of the belly cavity on both sides of the I-beam body 1 is fitted with an upper reinforcing plate 9 that cooperates with the support plate 8.
