The connecting plate 6 and the positioning plate 5 are located on the same vertical plane and a gap is left between the connecting plate 6 and the positioning plate 5.

[0039] The adjusting rod 7 is arranged in the gap between the connecting plate 6 and the positioning plate 5 , and is used to adjust the distance between the connecting plate 6 and the positioning plate 5 .

[0040] Optionally, the support plate 3 is an isosceles right triangle, two right-angled sides of the support plate 3 are fixedly connected to the transverse partition 2 and the web 102 respectively, and the support plate 3 and the beam surface 101 of the T-beam 1 are parallel to each other.

[0041] Optionally, a through groove 201 is formed on the side wall of the transverse partition 2 , and the connecting plate 6 is arranged in the through groove 201 .

[0042] Optionally, the adjusting rod 7 is a double-ended stud, and the threads at both ends of the adjusting rod 7 have opposite rotation directions.

[0043] A method for reinforcing a structure of a T-beam diaphragm comprises the following steps:

[0044] S1, chiseling away the damaged, loose or corroded concrete on the diaphragm 2 to be reinforced and the concrete on the web 102 corresponding to the diaphragm 2 to be reinforced, until the steel bars inside the diaphragm 2 and the web 102 are exposed;

[0045] S2, welding the two ends of the reinforcing steel bar to the steel bars inside the diaphragm 2 and the web 102 respectively;

[0046] S3, pouring concrete on the outer side of the reinforced steel bar to form a support plate 3, and then curing the support plate 3;

[0047] S4, welding the frame 1 and the frame 2 at the middle position between the two transverse diaphragms 2 on the web 102, and then pouring concrete on the frame 1 and the frame 2 to form a fixing plate 4 and a positioning plate 5;

[0052] S8. Overall curing and maintenance.

[0053] Optionally, after the reinforcement steel bars, frame one, frame two, and frame three are welded, an anti-rust paint layer is applied on the surface for anti-corrosion treatment.

[0054] Optionally, before pouring concrete, locations of damaged, loose or corroded concrete on the web 102 and the diaphragm 2 are chiseled out for dust removal and roughening.

[0055] The working process of this embodiment is as follows:

[0056] Before reinforcing the diaphragm 2, firstly, the damaged, loose or corroded concrete on the outer side of the diaphragm 2 is chiseled out. It is only necessary to chisel out the concrete corresponding to the internal steel bars to expose the steel bars, and the concrete at other positions does not need to be chiseled out. Then, the concrete is chiseled out at the position corresponding to the diaphragm 2 on the web 102 to expose the internal steel bars, and then the reinforcing steel bars are welded to the exposed steel bars of the diaphragm 2 and the web 102. After welding is completed, all exposed steel bars and reinforcing steel bars are coated with a layer of paint for rust prevention. Then, the positions where the concrete is chiseled out of the diaphragm 2 and the web 102 are roughened to remove dust, and an uneven contact surface is made on the concrete surface. Then, the casting template is installed on the outer side of the reinforcing steel bars to start pouring concrete. After the concrete is solidified, the template is removed and the solidified concrete is cured to form a support plate 3. After the support plate 3 is poured, the web 102 is used to cast the support plate 3. The concrete is chiseled out in the middle position between the upper two transverse diaphragms 2 to expose the steel bars, and then the frame 1 and the frame 2 are welded on the steel bars. The frame 1 is perpendicular to the web 102 as a whole, and the frame 1 and the frame 2 are "T" shaped as a whole. After welding, they are painted for rust prevention, and then concrete is poured to form the fixed plate 4 and the positioning plate 5. During the pouring of the positioning plate 5, nuts are pre-embedded at their ends. After the fixed plate 4 and the positioning plate 5 are solidified, one end of the adjusting rod 7 is screwed into the nut, and a nut is also screwed on the other end of the adjusting rod 7. After that, a through groove 201 is chiseled out on the side wall of the end of the transverse diaphragm 2 away from the web 102, and the steel bars in the through groove 201 are exposed, and the frame 3 is welded on the steel bars. After welding, it is treated for rust prevention, and then the connecting plate 6 is cast. During the pouring of the connecting plate 6, the nut installed at the other end of the adjusting rod 7 needs to be buried in the concrete. After the pouring is completed, wait for the concrete to solidify.

[0057] The present invention integrates a plurality of transverse partitions 2 on a T-beam 1 from respective independent states into an integrated state, thereby effectively improving the reinforcing effect between the plurality of transverse partitions 2 and the reinforcing effect of the transverse partitions 2 on the T-beam 1 .

[0058] Embodiment 2:

[0059] Reference Figure 2 As shown, the difference between this embodiment and the first embodiment is that two receiving grooves 8 are provided at the bottom end of the beam surface 101, and the two receiving grooves 8 are symmetrically arranged on both sides of the web 102. A connecting block 10 is fixedly connected to the middle of the top end of the diaphragm 2, and the connecting block 10 is adapted to the receiving groove 8 and is arranged in the receiving groove 8. A first tension rod 9 is arranged in each of the accommodating grooves 8, and the first tension rod 9 passes through the connecting block 10 located in the middle position in sequence and both ends are fixedly connected to the connecting block 10 located at the end respectively. The first tension rod 9 is in a stretched state. In this embodiment, all the diaphragms 2 are combined into a whole by tension through the first tension rod 9.

[0060] Embodiment three:

[0061] Reference Figure 3 As shown, the difference between this embodiment and the first embodiment is that a second tension rod 11 is fixedly connected between any two adjacent transverse partitions 2, and the second tension rod 11 is in a tensile state. In this embodiment, a plurality of second tension rods 11 combine all the transverse partitions 2 into a whole through tension.
