[0029] By providing the adhesive structural layer, the corner reinforcement member 21 , the reinforcing rib 22 and the connecting plate 23 are integrated with the existing structural column 11 , the existing structural beam 12 and the existing structural floor slab 13 .

[0030] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the reinforcement structure of the existing structural beam column of the utility model further includes a reinforcing hoop plate 24 hooped around the outer periphery of the existing structural column 11 , and the reinforcing hoop plate 24 is fixedly connected to the corresponding corner reinforcement member 21 .

[0031] The reinforcing hoop plate 24 serves to increase the structural strength. The reinforcing hoop plate 24 is connected to the corner reinforcement member 21 and is used to increase the structural strength of the corner reinforcement member 21 and the existing structural column 11 .

[0032] Further, the reinforcing hoop plates 24 are arranged at the connection between the existing structural column 11 and the existing structural beam 12 and at the connection between the existing structural column 11 and the existing structural floor slab 13. That is, the reinforcing hoop plates 24 are arranged at the top and bottom of the existing structural column 11 to reinforce the top and bottom of the existing structural column 11.

[0033] Preferably, the reinforcing hoop plate 24 is hooped on the outside of the corner reinforcement member 21, and the reinforcing hoop plate 24 is made of a strip metal plate of 80mm*4mm, such as a steel strip.

[0034] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the existing structural column 11 of the present invention is a square column with four corners; the corner reinforcement member 21 is L-shaped and is buckled at the corresponding corners of the existing structural column 11.

[0035] The corner reinforcements 21 are arranged at the four corners of the existing structural column 11, and the connecting plates 23 are connected between two adjacent corner reinforcements 21 and are arranged at intervals along the corner reinforcements 21. The connecting plates 23 on the adjacent sides are arranged at the same height, so that the connecting plates 23 around the square column are connected to the corner reinforcements 21 to form hoop plates, which can play a role in reinforcing the corner reinforcements 21.

[0036] Furthermore, the connecting plates 23 are provided in multiple rows and arranged at intervals. The connecting plates 23 are preferably 40 mm*4 mm strip metal plates, such as steel strips, and the connecting plates 23 are provided at intervals of 200 mm.

[0037] Furthermore, the reinforcement hoop plate 24 is also connected between two adjacent corner reinforcement members 21. The heights of the reinforcement hoop plates 24 on the adjacent two sides are consistent, so that the reinforcement hoop plates 24 on the periphery of the four corner reinforcement members 21 are connected to the corner reinforcement members 21 to form a square hoop plate structure with high strength and good stability.

[0038] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the corner reinforcement member 21 passes through the existing structural floor slab 13 and is injected with adhesive to form a first structural adhesive layer. The injected adhesive is epoxy resin adhesive.

[0039] A through hole is chiseled out on the existing structural floor 13 at the location corresponding to the corner reinforcement 21, which passes through the upper and lower surfaces of the existing structural floor 13. The size of the through hole is larger than the size of the corner reinforcement 21. After the corner reinforcement 21 passes through the through hole, epoxy resin adhesive is poured between the hole wall of the through hole and the corresponding position of the corner reinforcement 21 for anchoring. The epoxy resin adhesive forms a first structural adhesive layer in the through hole, and the first structural adhesive layer connects the existing structural floor 13 and the corner reinforcement 21.

[0040] In a specific embodiment of the present invention, Figure 1 and Figure 2 As shown, the reinforcing rib 22 passes through the existing structural beam 12 and is injected with adhesive to form a second structural adhesive layer. The injected adhesive is epoxy resin adhesive.

[0041] A through hole is drilled on the existing structural beam 12 at the location corresponding to the setting of the reinforcing rib 22 to form a through hole that penetrates the two side surfaces. The size of the through hole is larger than the size of the reinforcing rib 22. After the reinforcing rib 22 passes through the through hole, epoxy resin adhesive is poured between the hole wall of the through hole and the corresponding part of the reinforcing rib 22 for anchoring. The epoxy resin adhesive forms a second structural adhesive layer in the through hole, and the second structural adhesive layer connects the existing structural beam 12 and the reinforcing rib 22. When setting the through hole, the through hole is drilled at the connection between the existing structural beam 12 and the existing structural column 11.

[0042] Furthermore, at least two reinforcing ribs 22 are provided.

[0043] Furthermore, the existing structural column 11 is connected with the existing structural beam 12 around it, and the reinforcing ribs 22 passing through the existing structural beam 12 are correspondingly arranged. In this way, the reinforcing ribs 22 around the existing structural column 11 are connected with the corner reinforcement 21 to form stirrups, which pass through the existing structural beam 12 and connect the four corner reinforcements 21.

[0044] Preferably, the reinforcing ribs 22 are made of Q355B steel.

[0045] In a specific implementation of the present invention, the adhesive structure layer is an epoxy resin adhesive layer.

[0046] Preferably, the corner reinforcement 21 is an angle steel with a size of 75 mm*5 mm.

[0047] The construction process of the reinforcement structure of the existing structural beams and columns of the utility model is described below.

[0048] Corner reinforcements are buckled at the four corners of the existing structural column, and two adjacent corner reinforcements are connected and fixed by connecting plates. The connecting plates connected to the outer sides of the four corner reinforcements are arranged at intervals on the side surfaces of the corresponding existing structural columns. Reinforcement hoops are set at the top of the existing structural column, that is, close to the existing structural beam, and at the bottom of the existing structural column, that is, close to the existing structural floor. The reinforcement hoops are strip-shaped and connected to the two adjacent corner reinforcements. The reinforcement hoops and the connecting plates are set in parallel. When the set corner reinforcement encounters the existing structural floor, the existing structural floor is chiseled to allow the corner reinforcement to pass through, and adhesive is poured at the position where it passes through for anchoring. Reinforcement ribs are passed through the existing structural beam at the position close to the existing structural column, and the reinforcement ribs are fixedly connected to the corresponding corner reinforcements. Adhesive is used to anchor the existing structural beam at the position where the reinforcement ribs are passed. Then, epoxy resin adhesive is poured into the gaps between the corner reinforcements, connecting plates, reinforcing ribs, reinforcing hoops and the outer sides of the existing structural columns for anchoring, and the installed corner reinforcements, connecting plates, reinforcing ribs, reinforcing hoops and the existing structural columns are connected into one, thereby improving the bearing capacity and seismic performance of the existing structure.

[0049] The utility model is described in detail above in conjunction with the embodiments of the drawings. A person skilled in the art can make various variations of the utility model according to the above description. Therefore, some details in the embodiments should not constitute a limitation of the utility model, and the scope of protection of the utility model shall be defined by the scope of the attached claims.
