AI Technical Summary
Existing beam reinforcement methods cannot effectively transfer the supporting force, resulting in poor reinforcement effect and failure to maintain the effective cross-sectional height and stress magnitude of the beam.
An opening is made in the lower part of the steel frame beam, and a supporting structure is formed by I-beams and concrete filling cavities. The supporting force is transferred to the steel frame column by using reinforcement components and supports, and reinforcement is carried out by chemical tie bolts and steel plates.
This method achieves the goal of keeping the effective cross-sectional height and stress magnitude of the beam unchanged, improving overall stability, and maintaining the same force transmission path. By increasing the beam cross-section through the concrete injection cavity, the original cross-sectional height is kept constant, thus enhancing the reinforcement effect of the beam.

[0002] In existing methods of reinforcing beams, fixing plates are mostly installed on the two sides and bottom of the beam to strengthen it. However, these methods can only reduce the stress in the middle of the beam and have a limited effect on strengthening the beam. They cannot transfer the reinforcing support force of the beam to achieve reinforcement. Furthermore, these reinforcement techniques cannot ensure that the effective cross-sectional height and stress magnitude of the beam remain unchanged. Summary of the Invention
[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a reinforcement structure for drilling holes at the lower end of the support of a frame beam.
[0004] The technical solution adopted by this utility model is as follows: it includes steel frame columns, and a steel frame beam is integrally formed between two steel frame columns, and also includes:

[0006] The reinforcement component, located above the steel frame beam, is used to provide support for the steel frame beam. The reinforcement component includes two oppositely distributed I-beams, forming a concrete injection cavity between the two I-beams. An embedded part is provided in the concrete injection cavity, and both ends of the embedded part extend to the steel frame column. A reinforcing plate is provided on one side of the I-beam, and the reinforcing plate is connected to the steel frame beam.

[0011] The concrete injection cavity is formed by the enclosing of the two I-beams, the continuous plate, and the connecting plate.
[0012] As a preferred embodiment of this utility model, the reinforcing plate is provided with:
[0013] A continuous steel plate is bonded between the steel frame beam and the reinforcing plate;
[0014] Tie holes penetrate the reinforcing plate and extend to the steel frame beam.
[0015] The tie bolts pass through the reinforcing plate, the bonded continuous steel plate, and the steel frame beam, and are used for tie-limiting between the reinforcing plates on both sides of the steel frame beam.
[0016] As a preferred embodiment of this invention, the tie bolt is a chemical tie bolt.
[0017] As a preferred embodiment of this invention, the reinforcing component further includes:
[0018] A steel plate is attached to the opening and is bonded to the bottom of the opening.

[0025] The beneficial effects of this utility model are as follows:
[0026] This utility model is a reinforcement structure for the lower part of the support end of a frame beam. By drilling holes in the lower part of the steel frame beam, with the hole height exceeding one-third of the beam height, it effectively ensures that the effective cross-sectional height of the drilled beam remains unchanged, the force transmission path remains unchanged, the force magnitude remains unchanged, and the overall stability remains unchanged. By forming a concrete injection cavity at the top of the steel frame beam and injecting concrete into the concrete injection cavity, the original frame beam is reinforced, so that its effective cross-sectional height remains unchanged. By using reinforcement plates and bonding steel plates, and bonding continuous steel plates, the integrity of the reinforced part and the original part is not changed, so that the stress of the steel frame beam is transferred to the steel frame column, thereby achieving reinforcement of the steel frame beam and the stability after reinforcement.

The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0034] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0035] The following is combined with Figure 1-4 This invention describes a specific embodiment of a frame beam support end reinforcement structure, comprising steel frame columns 1, a steel frame beam 2 integrally formed between two steel frame columns 1, and further comprising:
[0036] An opening 23 is provided at one end of the steel frame beam 2 near the steel frame column 1. The opening 23 is located at the lower part of the steel frame beam 2 and serves as a support for reinforcing the steel frame beam 2.
[0037] The reinforcement component 3, located above the steel frame beam 2, provides support for the steel frame beam 2. The reinforcement component 3 includes two opposing H-beams 32, forming a concrete injection cavity 37 between the two H-beams 3. By forming a concrete injection cavity 37 above the steel frame beam 2, concrete can be poured into the concrete injection cavity 37 to form a supporting structure for the steel frame beam 2, thus providing support for the original steel frame beam 2. An embedded part 11 is provided in the concrete injection cavity 37. The two ends of the embedded part 11 extend to the steel frame column 1 and pass through the concrete injection cavity 37. At the same time, its two ends are inserted into the steel frame column 1 to improve the stability of the concrete in the concrete injection cavity 37 after solidification and the steel frame column 1. A reinforcing plate 34 is provided on one side of the H-beam 32. The reinforcing plate 34 is connected to the steel frame beam 2 and is used to support the steel frame beam 2 by the solidified concrete wall in the concrete injection cavity 37, thereby reinforcing the steel frame beam 2.
[0038] The support member 4 is connected at its top to the opening 23 at the bottom of the steel frame beam 2 and at its other side to the steel frame column 1. The support member 4 is used to position the steel frame beam 2 and can also be used to position the reinforcement member 3 on the steel frame column 1.
[0039] Please refer to Figures 1-3 As shown, the reinforcement component 3 further includes:
[0040] A continuous plate 33 is located on top of the I-beam 32 and is welded to the I-beam 32, serving as a sealing plate after concrete is poured into the concrete filling cavity 37;
[0041] The connecting plate 38 is located at the lower end of the I-beam 32, and its two ends are fixedly connected to the I-beam 32 to seal the lower end of the concrete filling cavity 37 to prevent leakage when pouring concrete into the concrete filling cavity 37.
[0042] The concrete filling cavity 37 is formed by the two I-beams 32, the continuous plate 33, and the connecting plate 38. The concrete filling cavity 37 is formed by the two I-beams 32 and the connecting plate 38, thereby forming a wall above the steel frame beam 2 to support the steel frame beam 2 and reinforce the steel frame beam 2.
[0043] Please refer to Figure 2-Figure 3 As shown, the reinforcing plate 34 is provided with:
[0044] A continuous steel plate 31 is placed between the steel frame beam 2 and the reinforcing plate 34. In the process of reinforcing the steel frame beam 2, the steel frame beam 2 is first ground and leveled, and the continuous steel plate 31 is then bonded to the steel frame beam 2 with adhesive to facilitate the uniformity of the force on the steel frame beam 2 by the reinforcing member 3.
[0045] The tie hole 21 penetrates the reinforcing plate 34 and extends to the steel frame beam 2;
[0046] The tie bolts 22 pass through the reinforcing plate 34, the bonded continuous steel plate 31 and the steel frame beam 2, and are used for tie limiting between the reinforcing plates 34 on both sides of the steel frame beam 2. The tie bolts 22 pass through the reinforcing plate 34, the bonded continuous steel plate 31 and the steel frame column 1 to reinforce and support both ends of the crossbeam.
[0047] Please refer to Figure 2-Figure 3 As shown, the tie bolt 22 is a chemical tie bolt 22, which has high strength and meets the reinforcement requirements of the steel frame beam 2.
[0048] Please refer to Figures 1-3 As shown, the reinforcement component 3 further includes:
[0049] The steel plate 36 is located at the opening 23 and is bonded to the bottom of the opening 23. Before the steel plate 36 is bonded to the bottom of the steel frame beam 2, the bottom of the steel frame beam 2 needs to be ground to improve the stability of the bond between the steel plate 36 and the steel frame beam 2.
[0050] Angle steel plates 35 are symmetrically distributed along the length of the adhesive steel plate 36.
[0051] Please refer to Figure 2 As shown, the support member 4 includes:
[0052] The support plate 41 has mounting holes 12. The support plate 41 is fixedly installed to the steel frame column 1 through the mounting holes 12. The support plate 41 is installed on the steel frame column 1 by expansion bolts and mounting holes 12 to provide positioning and support for the reinforcement 3.
[0053] The top of the support plate 41 abuts against the angle steel plate 35 to provide support for the reinforcement of the steel frame beam 2.
[0054] Please refer to Figure 1 and Figure 4 As shown, a steel plate 14 is provided on the side of the steel frame column 1 near the steel frame beam 2. The steel plate 14 is fixedly connected to the embedded part 11. Embedded holes 13 are provided on the steel plate 14, extending to the steel frame column 1. The steel plate 14 is fixedly connected to the steel frame column 1, and multiple embedded holes 13 are provided on the steel plate 14 for inserting the embedded part 11. Figure 1 The diagram shows only one side of the support member 4.
[0055] Please refer to Figure 1As shown, the embedded part 11 passes through the concrete filling cavity 37, and its two ends are respectively inserted into the embedded hole 13. By embedding the embedded part 11 into the concrete filling cavity 37, the strength of the concrete in the concrete filling cavity 37 after solidification is improved, so that the reinforcement of the steel frame beam 2 is transferred to the steel frame columns 1 at both ends of the steel frame beam 2.
[0056] Working principle of this utility model:
[0057] A hole is made at the lower third of one end of the steel frame beam 2. A metal detector is used on the steel frame column 1 to detect the metal position and a pre-embedded hole 13 is made to avoid the metal position. Pre-embedded parts 11 are arranged between the two steel frame columns 1 and the pre-embedded parts 11 are inserted into the pre-embedded hole 13.
[0058] The two sides of the steel frame beam 2 and the ground are ground, and the reinforcing plate 34 is bonded to the two sides by using adhesive. The steel plate 36 is bonded to the bottom of the steel frame beam 2 to improve the stability of the steel frame beam 2 under stress.
[0059] A support plate 41 is installed on the side of the steel frame column 1 near the steel frame beam 2. The installation height of the support plate 41 is set according to the height of the reinforcement 3, so that the support plate 41 is fixedly installed on the steel frame column 1, so that it provides positioning and support for the reinforcement 3. When installing the support 4, an angle steel plate 35 is set at the bottom of the adhesive steel plate 36, so that the angle steel plate 35 is located between the adhesive steel plate 36 and the support plate 41.
[0060] A reinforcing plate 34 is installed on the top of the angle steel plate 35, so that the bottom of the reinforcing plate 34 is connected to the top of the angle steel plate 35, and one side of the reinforcing plate 34 is attached to the continuous steel plate 31. Since the continuous steel plate 31 on both sides of the steel frame beam 2, the through holes and the tie holes 21 on the reinforcing plate 34 are on the same straight line, the tie holes 21 are installed in the tie holes 21 to limit the tension between the reinforcing plates 34 on both sides of the steel frame beam 2. I-beams 32 are installed in the top of the two reinforcing plates 34. The two I-beams 32 are arranged opposite each other, and a connecting plate 38 is installed between the bottom of the two I-beams 32, so that the connecting plate 38 is attached to the top of the steel frame beam 2. When the two reinforcing plates 34 are locked by tie, the two I-beams 32 move synchronously and form a concrete injection cavity 37 between the two I-beams 32 and the connecting plate 38.
[0061] Concrete is poured into the concrete injection cavity 37. After the concrete solidifies, it forms an integral structure with the embedded part 11, fixing the I-beam 32 and the reinforcing plate 34. The solidified wall reinforces the steel frame beam 2 through the reinforcing plate 34. At the same time, the support part 4 supports the steel frame beam 2 to achieve reinforcement of the steel frame beam 2, so that the force of the steel frame beam 2 is transferred to the steel frame column 1.
