Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular relates to a component for reinforcing circular holes in the web of beams in building engineering. Background Technology

[0002] In building construction, circular openings in the web of beams are primarily used for pipeline passage (such as water, electricity, and HVAC pipes), avoiding the occupation of space under the beam and optimizing building height and layout. These openings can reduce the structure's self-weight (approximately 10%-15%), lowering material costs and foundation load, offering both economic and environmental benefits. Circular openings have lower stress concentration at their edges, making them more effective at dispersing localized stress and reducing the risk of cracking compared to square openings. Properly placed openings can also adjust beam stiffness and improve overall load-bearing performance. Pre-drilled openings during construction facilitate equipment passage and assembly, improving efficiency and reducing damage to the structure from later openings. During design, high shear force areas (such as the beam end 1 / 3 span) should be avoided, and the opening diameter should generally not exceed 40% of the web height. Large openings require additional ring stiffening plates for reinforcement. This scientific application achieves synergy between function and structure, and is an important technical means for lightweight building construction, integration, and green construction.

[0003] While some methods can moderately reinforce circular openings in beam webs by directly welding annular stiffening plates to the outer edge of the openings, the lack of connection between the annular stiffening plates and the steel beam flanges leaves room for improvement in the stability of the annular stiffening plates themselves. Therefore, a reinforcement component for circular openings in beam webs is needed in building engineering. This component could connect the annular stiffening plates to the steel beam flanges, improve the stability of the annular stiffening plates, thereby enhancing the reinforcement effect of the annular stiffening plates on the circular openings and ultimately improving the structural rigidity of the beam web openings. Utility Model Content

[0009] Preferably, a diagonal brace is welded between the vertical rod and the horizontal plate.

[0010] The beneficial effects of this utility model are:

[0011] This utility model uses the combination of uprights and arc-shaped connecting blocks to fix the annular stiffening plate to the horizontal plate, and the connection of the vertical rods allows the two horizontal plates to be connected as a whole, improving the stability of the structure. This achieves the purpose of connecting the annular stiffening plate to the steel beam flange, improving the stability of the annular stiffening plate itself, thereby improving the reinforcement effect of the annular stiffening plate on the circular hole, and ultimately improving the rigidity of the beam web hole structure.

[0012] 2. By setting an elastic washer, this utility model increases the friction on the surface of the bolt rod, preventing the bolt rod from coming out of the inner cavity of the threaded hole due to external force vibration, thereby improving the stability of the bolt rod position;

[0013] 3. This utility model uses the combination of slots and inserts to pre-fix the upright and the horizontal plate, making the subsequent welding between the two more precise, thereby improving the welding accuracy between the upright and the horizontal plate.

[0023] In the following description, embodiments of the circular hole reinforcement component for beam webs in building engineering according to the present invention will be described with reference to the accompanying drawings. Example 1

[0024] Figure 1-4 This invention illustrates a beam web circular hole reinforcement component in a building engineering project according to an embodiment of the present invention. It includes an annular stiffening plate 1. An I-beam 2 is welded to the surface of the annular stiffening plate 1. Two symmetrically arranged horizontal plates 3 are welded to the surface of the I-beam 2. Vertical rods 4 are arranged on the surface of the horizontal plates 3. Threaded holes 5 are formed on the surface of the horizontal plates 3. Bolts 6 are inserted through the surface of the vertical rods 4, with the ends of the bolts 6 penetrating the vertical rods 4 and extending into the inner cavity of the threaded holes 5. Through holes adapted to the bolts 6 are formed on the surface of the vertical rods 4. Elastic washers 7 are fitted onto the surface of the bolts 6. The elastic washers 7 increase the friction on the surface of the bolts 6, preventing the bolts 6 from collapsing due to external forces. The vibration causes the bolt rod 6 to come loose from the inner cavity of the threaded hole 5, thereby improving the stability of the bolt rod 6. A vertical rod 8 is welded to the surface of the horizontal plate 3, and an arc-shaped connecting block 9 is welded to the surface of the vertical rod 8. The arc-shaped connecting block 9 is welded to the annular stiffening plate 1. An L-shaped part 10 is welded together between the vertical rod 8 and the horizontal plate 3. A slot 11 is opened on the surface of the horizontal plate 3, and an insert 12 is integrally formed on the surface of the vertical rod 8. The insert 12 is inserted into the inner cavity of the slot 11. Through the cooperation of the slot 11 and the insert 12, the vertical rod 8 and the horizontal plate 3 are pre-fixed, making the subsequent welding between the two more precise, thereby improving the welding accuracy between the vertical rod 8 and the horizontal plate 3. Example 2

[0025] Figure 1-4This invention illustrates a beam web circular hole reinforcement component in a building construction project according to an embodiment of the present invention. It includes an annular stiffening plate 1; an I-beam 2 is welded to the surface of the annular stiffening plate 1; two symmetrically arranged horizontal plates 3 are welded to the surface of the I-beam 2; vertical rods 4 are provided on the surface of the horizontal plates 3; threaded holes 5 are formed on the surface of the horizontal plates 3; bolt rods 6 penetrate the surface of the vertical rods 4, with the ends of the bolt rods 6 penetrating the vertical rods 4 and extending into the inner cavity of the threaded holes 5; uprights 8 are welded to the surface of the horizontal plates 3; arc-shaped connecting blocks 9 are welded to the surface of the uprights 8; the arc-shaped connecting blocks 9 are welded to the annular stiffening plate 1; and the uprights 8 and the horizontal plates 3 are connected together. An L-shaped part 10 is welded on the surface of the arc-shaped connecting block 9, and a groove 13 is opened on the surface of the arc-shaped connecting block 9. The inner wall of the groove 13 and the surface of the upright 8 are filled with a structural adhesive layer 14. Through the cooperation of the groove 13 and the structural adhesive layer 14, the arc-shaped connecting block 9 and the upright 8 are pre-fixed, so that the position of the two is stable before welding, which improves the accuracy of the connection when the two are welded and fixed. A diagonal bar 15 is welded between the vertical bar 4 and the horizontal plate 3. The diagonal bar 15 is set to reinforce the connection between the vertical bar 4 and the horizontal plate 3, forming a triangular structure, which further improves the integrity and stability of the connection between the horizontal plate 3 and the vertical bar 4.

[0026] Working principle: When using this utility model, the user welds the horizontal plate 3 to the flange of the I-beam 2, and then the vertical rod 8 and the arc-shaped connecting block 9 are used together to fix the annular stiffening plate 1 to the horizontal plate 3. The bolt rod 6 is threaded to the inner wall of the threaded hole 5, so that the vertical rod 4 can connect the horizontal plate 3 into a whole. The L-shaped part 10 is set to reinforce the welding between the horizontal plate 3 and the vertical rod 8, which improves the stability of the connection between the two. Then, the arc-shaped connecting block 9 and the I-beam 2 are welded to the annular stiffening plate 1, which strengthens the outer edge of the circular opening of the I-beam 2, improves the stability of the structure, realizes the connection between the annular stiffening plate and the flange of the steel beam, improves the stability of the annular stiffening plate itself, thereby improving the effect of the annular stiffening plate on reinforcing the circular hole, and thus improving the rigidity of the beam web opening structure.

[0027] In summary, the circular hole reinforcement component in the beam web of this building project, through the combined use of the uprights 8 and the arc-shaped connecting blocks 9, allows the annular stiffening plate 1 to be fixed to the horizontal plate 3. Furthermore, through the connecting action of the vertical rods 4, the two horizontal plates 3 are connected as a whole, improving the structural stability. This achieves the goal of connecting the annular stiffening plate to the steel beam flange, improving the stability of the annular stiffening plate itself, thereby enhancing the reinforcement effect of the annular stiffening plate on the circular hole, and ultimately improving the structural rigidity of the beam web hole.
