[0031] The present invention will now describe a core-column reinforced wall structure.

[0032] The core-column reinforced wall includes a wall to be reinforced 1, reinforcing bars 2, and filler. The wall to be reinforced 1 has a vertically formed groove 11. The top of the wall to be reinforced 1 is connected to an upper ring beam 10, and the bottom of the wall to be reinforced 1 is connected to a lower ring beam 20. The reinforcing bars 2 are embedded in the groove 11. The length of the reinforcing bars 2 is greater than the height of the wall to be reinforced 1, and both ends of the reinforcing bars 2 are respectively embedded and connected to the upper ring beam 10 and the lower ring beam 20. The filler is filled into the groove 11 to connect the reinforcing bars 2 to the wall to be reinforced 1.

[0033] The upper ring beam 10 and the lower ring beam 20 are respectively provided with a first groove 101 and a second groove 201, which are used to accommodate the top and bottom of the reinforcing bar 2, respectively.

[0034] This embodiment provides a core-column reinforced wall system. Compared with the prior art, this application includes a wall to be reinforced 1, reinforcing bars 2, and filler. The reinforcing bars 2 are embedded in grooves 11 on the wall to be reinforced 1, and both ends of the reinforcing bars 2 are respectively embedded in the upper ring beam 10 and the lower ring beam 20. The grooves 11 are filled with filler, which connects the reinforcing bars 2 and the wall to be reinforced 1 into a single unit.

[0035] In some embodiments, the core column reinforced wall also includes an adhesive material, which is filled into the first groove 101 and the second groove 201. The adhesive material fills the first groove 101 and the second groove 201, and bonds the two ends of the reinforcing bar 2 to the upper ring beam 10 and the lower ring beam 20 respectively, so as to prevent the reinforcing bar 2 from separating from the upper ring beam 10 and the lower ring beam 20.

[0036] Specifically, the adhesive material uses epoxy resin, which is suitable for various metal composite materials such as aluminum, steel, iron, and copper; non-metallic materials such as laminated glass, wood, and concrete; and polyurethane elastomers such as phenolic resin, hydroxyl, and unsaturated polyester. It possesses excellent adhesive properties and is therefore called a general-purpose adhesive. Epoxy adhesives are an extremely important type of structural adhesive.

[0095] Preparation process

[0096] The manufacturing process of polyacrylonitrile-based carbon fiber includes two processes: precursor fiber production and precursor fiber carbonization. Precursor fiber production mainly involves polymerization, degassing, metering, spinning, traction, washing, oiling, drying, and winding.

[0097] The preparation process of pitch-based carbon fiber is as follows: After the raw pitch is refined by solvent extraction, sedimentation separation and distillation, it is modified by oxidative thermal polymerization to obtain spinnable pitch, which is then spun to obtain pitch raw fibers. Finally, pitch-based carbon fiber is obtained through non-melting (stabilization at 200-400℃) treatment and carbonization (under nitrogen protection at 600-1500℃).

[0098] Application areas

[0099] In the aerospace field: it is used to manufacture structural components such as aircraft wings, fuselages, and tail fins, which can reduce aircraft weight, improve fuel efficiency and flight performance, while ensuring structural strength and reliability.

[0102] In the field of medical equipment: it can be used to manufacture CT beds, prostheses, orthopedic instruments, etc., with good biocompatibility and mechanical properties, which can provide patients with better treatment and rehabilitation conditions.

[0103] Based on the above embodiment, two vertically arranged reinforcing bars 2 are provided in the trench 11. The two reinforcing bars 2 are arranged in parallel in the trench 11, and the two ends of the reinforcing bars 2 are respectively embedded in the first groove 101 and the second groove 201. The presence of two vertically arranged reinforcing bars 2 in one trench 11 enhances the connection strength between the wall 1 to be reinforced and the upper ring beam 10 and the lower ring beam 20.

[0104] Furthermore, there are two grooves 11, which are respectively arranged in parallel at both ends of the length of the wall 1 to be reinforced. The arrangement of the two grooves 11 enhances the connection strength between the wall 1 to be reinforced and the upper ring beam 10 and the lower ring beam 20.

[0105] The cross-sections of the first groove 101 and the second groove 201 are wedge-shaped. Setting the cross-sections of the first groove 101 and the second groove 201 as wedge-shaped facilitates the insertion of the reinforcing bar 2. At the same time, the wedge-shaped design (the dimension of the end closer to the wall 1 to be reinforced is smaller than the dimension of the end farther away from the wall 1 to be reinforced) can prevent the reinforcing bar 2 from detaching from the first groove 101 or the second groove 201 when the wall 1 to be reinforced shakes.

[0106] Based on the above embodiment, both ends of the reinforcing bar 2 are equipped with a riveting structure 3. The riveting structure 3 includes a connector 31, multiple elastic parts 32, and a binding rope 33. The connector 31 is sleeved on the end of the reinforcing bar 2. The multiple elastic parts 32 are spaced apart along the circumference of the reinforcing bar 2, and the central axis of the elastic part 32 is set at an angle to the central axis of the reinforcing bar 2. One end of the elastic part 32 is fixedly connected to the connector 31, and the other end of the elastic part 32 has a degree of freedom of movement. The outer surface of the elastic part 32 is provided with a mounting groove 321. The binding rope 33 is embedded in the mounting groove 321 and is used to bind the multiple elastic parts 32.

[0107] When the connector 31 is fitted onto the end of the reinforcing bar 2, the connector 31 is inserted into the first groove 101 or the second groove 201, the binding rope 33 is untied, the elastic part 32 rebounds, and the outer side wall of the elastic part 32 abuts against the inner side wall of the first groove 101 or the second groove 201. After the abutment is completed, the adhesive material is filled into the first groove 101 or the second groove 201, thereby connecting the two ends of the reinforcing bar 2 to the upper ring beam 10 and the lower ring beam 20 respectively to form a whole.

[0108] Specifically, the elastic part 32 has an arc-shaped structure.

[0109] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
