Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically to a base reinforcement and support device for a steel I-beam. Background Technology

[0002] Steel structure buildings are common in industrial and agricultural fields due to their lower construction costs and shorter construction periods. I-beams are often used as support columns in steel structure buildings. The bottom of the support column must bear not only the weight of the building but also its own weight. Therefore, it is necessary to reinforce the bottom of the support column. Support columns in general brick or reinforced concrete structures can still be reinforced by pouring reinforced concrete. However, the connection strength between steel I-beams and concrete is limited. Usually, additional parts are welded to the side wall of the I-beam for reinforcement, but the reinforcement effect is very limited.

[0003] In the prior art, the patent with authorization announcement number CN 217759590 U, entitled "Utility Model Patent for a Base Reinforcement Support Device for Building Engineering", provides a base reinforcement method. However, the first fixing seat in the solution is fixed by drilling holes in the flange plate of the I-beam, which reduces the structural strength of the I-beam itself. At the same time, the second fixing seats on both sides occupy a large space, which is inconvenient to use on the construction site. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a base reinforcement support device for steel I-beams, which solves the problems of damaging the structure of the I-beam itself and occupying a large construction space when reinforcing the base of a steel I-beam.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a base reinforcement support device for a steel I-beam, comprising a vertically arranged I-beam, a fixed base plate at the bottom of the I-beam, and several sets of through holes opened on the base plate for fixing expansion bolts;

[0006] Reinforcing ribs are provided on the left and right sides of the bottom of the I-beam in the direction perpendicular to the flange plate.

[0007] Fixing blocks are provided on the front and rear sides of the web of the I-beam, and the fixing blocks on the front and rear sides are fixed together by tie bolts.

[0008] Optionally, the reinforcing rib is disposed in the middle of the flange of the I-beam, and the thickness of the reinforcing rib is the same as the thickness of the web of the I-beam.

[0009] Optionally, the fixing block has grooves spaced apart on the side facing the web, and the flange of the I-beam is adapted to be inserted into the grooves.

[0010] Optionally, a first connecting hole is provided on the reinforcing rib, and a second connecting hole is provided on the fixing block at the position corresponding to the first connecting hole. The second connecting hole and the first connecting hole are used for fixing with tie bolts.

[0011] Optionally, the reinforcing rib is a right triangle, with the two right-angled sides of the right triangle respectively attached to the base plate and the flange of the I-beam.

[0012] Optionally, the reinforcing rib is fixedly connected to the base plate, and the reinforcing rib is fixedly connected to the flange of the I-beam.

[0013] This utility model provides a base reinforcement and support device for steel I-beams, which has the following beneficial effects:

[0014] This utility model provides a base reinforcement support device for steel I-beams. The device uses reinforcing ribs fixed to both sides of the I-beam's flange to provide diagonal bracing for the vertical I-beam, eliminating the need for additional diagonal bracing on the outside of the base plate and reducing space occupation. Simultaneously, the fixing blocks, held in place by tie bolts, effectively fill the bottom of the I-beam, increasing the contact area between the bottom of the I-beam and the base plate, further improving the vertical stability of the I-beam. Furthermore, the tie bolts used to fix the fixing blocks are connected through through holes in the reinforcing ribs, without drilling holes in the I-beam itself, protecting the structural integrity of the I-beam and improving construction convenience.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Please see Figures 1 to 3This utility model provides a technical solution: a base reinforcement support device for a steel I-beam, including a vertically arranged I-beam 1, a fixed base plate 2 at the bottom of the I-beam 1, and several sets of through holes on the base plate 2 for fixing expansion bolts 3; reinforcing ribs 4 are arranged on the left and right sides of the bottom of the I-beam 1 in the direction perpendicular to the flange plate 11, the reinforcing ribs 4 are located in the middle of the flange plate 11 of the I-beam 1, the reinforcing ribs 4 can provide diagonal support for the I-beam 1 from both sides to ensure the vertical stability of the I-beam 1; fixing blocks 5 are arranged on the front and rear sides of the web plate 12 of the I-beam 1, and the fixing blocks 5 on the front and rear sides are fixed together by tie bolts 6. The fixing blocks 5 are equivalent to filling the bottom of the I-beam 1, increasing the contact area between the bottom of the I-beam 1 and the base plate 2, further ensuring the vertical stability of the I-beam 1.

[0021] In this embodiment, as a preferred option, the thickness of the reinforcing rib 4 is the same as the thickness of the web 12 of the I-beam 1. On the one hand, this makes the structure symmetrical, aesthetically pleasing, and with balanced stress. On the other hand, it makes the structures of the two sets of fixing blocks 5 consistent, which is convenient for processing and manufacturing. The fixing blocks 5 have grooves 502 spaced apart on the side facing the web 12. The flange 11 of the I-beam 1 is adapted to be inserted into the grooves 502. The fixing blocks 5 can completely fit the I-beam 1 from the side, making the structure of the fixing blocks 5 connected to the bottom of the I-beam 1 more compact and improving the overall integrity of the bottom of the I-beam 1 in contact with the base plate 2.

[0022] In this embodiment, as a preferred solution, a first connecting hole 401 is opened on the reinforcing rib 4, and a second connecting hole 501 is opened on the fixing block 5 corresponding to the position of the first connecting hole 401. The second connecting hole 501 and the first connecting hole 401 are used for fixing with tie bolts 6. The front and rear fixing clamps of the fixing block 5 are fastened by passing through the first connecting hole 401 on the reinforcing rib 4, without having to make holes in the I-beam 1, which reduces the construction difficulty and ensures the structural integrity of the I-beam 1 itself.

[0023] In this embodiment, as a preferred option, the reinforcing rib 4 is a right triangle, with the two right-angled sides of the right triangle respectively attached to the flange plate 11 of the base plate 2 and the I-beam 1. The reinforcing rib 4 is fixedly connected to the base plate 2, and the reinforcing rib 4 is fixedly connected to the flange plate 11 of the I-beam 1, ensuring that the reinforcing rib 4, the I-beam 1, and the base plate 2 are tightly connected, making the entire structure more stable.

[0024] In this invention, the working steps of the device are as follows:

[0025] 1. Fix the base plate 2 by welding the base plate 2 to the vertically set I-beam 1 base plate 2;

[0026] 2. Fix the reinforcing rib 4. Weld the reinforcing rib 4 in the center of the outer side of the flange 11 at the bottom of the I-beam 1, perpendicular to the flange 11. Weld the reinforcing rib 4 fully to all the positions where it contacts the I-beam 1 and the bottom plate 2.

[0027] 3. Place the fixing block 5 and snap it into the front and rear directions of the I-beam 1 respectively, so that the groove 502 of the fixing block 5 is snapped into the flange plate 11 of the I-beam 1.

[0028] 4. Tighten the tie bolts 6 so that they pass through the second connecting hole 501 of the fixing block 5 and the first connecting hole 401 of the reinforcing rib plate 4, and lock the nuts of the tie bolts 6 from both the front and rear sides.
