Description

Technical Field

[0001] This utility model relates to the field of reinforced concrete beam reinforcement technology, and more specifically, to a carbon fiber cloth reinforced reinforced concrete beam. Background Technology

[0002] Reinforced concrete beams are beams made of reinforced concrete. They can be used as independent beams, integrated with reinforced concrete slabs to form beam-slab floor systems, or integrated with reinforced concrete columns to form single-story or multi-story frames. Reinforced concrete beams come in a variety of forms and are the most basic load-bearing components in building construction, bridge construction, and other engineering structures, with extremely wide applications. When repairing some buildings, it is necessary to reinforce their concrete beams.

[0003] A search revealed that utility model patent CN205777638U discloses a carbon fiber reinforced reinforced concrete beam, comprising a fixed column, L-shaped steel anchor plates, and U-shaped clamps. The top of the fixed column is connected to the beam body, and two L-shaped steel anchor plates are connected to both sides of the fixed column through through-column anchor rods. The bottom of the beam body is connected to the carbon fiber reinforced layer through an adhesive layer, and the bottom of the carbon fiber reinforced layer is connected to an insulation layer. The two sides of the U-shaped clamps are connected to the beam body through anchor bolts. One side of the L-shaped steel anchor plate is connected to the beam body and the top steel plate through through-beam anchor rods. The U-shaped clamps make the connection between the carbon fiber reinforced layer and the beam body more secure. L-shaped steel anchor plates are set at the angle between the fixed column and the beam body, and the two L-shaped steel anchor plates are tightly connected to strengthen the beam. An insulation layer is set at the bottom of the carbon fiber reinforced layer to prevent the carbon fiber from oxidizing at high temperatures. However, the above patent still has the following shortcomings: Although installing carbon fiber cloth at the bottom of the crossbeam through U-shaped clamps and L-shaped steel anchor plates can play a certain role, the pressure on the crossbeam can only be transmitted to the fixed column through the part connected to the fixed column. The reinforcement effect needs to be improved. Therefore, we propose a carbon fiber cloth reinforcement for reinforced concrete beams. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a carbon fiber cloth reinforced reinforced concrete beam.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A carbon fiber reinforced reinforced concrete beam includes a fixed column, a concrete crossbeam fixedly connected to the top of the fixed column, and U-shaped carbon fiber cloth sleeved on the lower parts of both ends of the concrete crossbeam. A triangular support mechanism is installed on the side of the fixed column and below the U-shaped carbon fiber cloth. The triangular support mechanism includes a side mounting plate installed on the side of the fixed column and a horizontal support plate installed below the U-shaped carbon fiber cloth. The top of the side mounting plate is connected to the end of the horizontal support plate, and multiple support frames are fixedly connected between the side of the side mounting plate and the bottom of the horizontal support plate.

[0007] As a preferred embodiment of this utility model, the side mounting plate is provided with a plurality of first mounting holes, and the inner cavity of each of the plurality of first mounting holes is fitted with a first bolt, and the ends of the plurality of first bolts are threaded into the interior of the fixing column.

[0008] As a preferred embodiment of this utility model, the horizontal support plate is provided with a plurality of second mounting holes, and a second bolt is fitted into the inner cavity of each of the plurality of second mounting holes. The ends of the second bolts are threaded through U-shaped carbon fiber cloth and installed into the interior of the concrete beam.

[0009] As a preferred embodiment of this utility model, the triangular support mechanism is manufactured by integral molding of carbon fiber.

[0010] In a preferred embodiment of this utility model, the two sides of the inner cavity of the U-shaped carbon fiber cloth are connected to the side of the concrete beam, and the bottom surface of the inner cavity of the U-shaped carbon fiber cloth is connected to the bottom surface of the concrete beam.

[0011] As a preferred embodiment of this utility model, the U-shaped carbon fiber cloth is bonded to the outside of the concrete beam using a high-performance carbon fiber-compatible resin impregnation adhesive.

[0012] Compared with the prior art, the advantages of the present invention are:

[0013] In this invention, a U-shaped carbon fiber cloth is installed below the concrete beam. The U-shaped structure of the carbon fiber cloth ensures that its bottom is not easily deformed, thus guaranteeing the strength of the carbon fiber cloth itself. At the same time, the U-shaped carbon fiber cloth can simultaneously reinforce the bottom and sides of the concrete beam, ensuring its reinforcement effect. In addition, a triangular support mechanism is installed at the corner of the fixed column and the concrete beam. The support frame on the triangular support mechanism allows the side of the fixed column to support the bottom of both ends of the concrete beam. The triangular support mechanism can directly transfer the force on both ends of the concrete beam to the fixed column, avoiding the problem that the support force can only be transferred through the connection between the concrete beam and the fixed column, thus improving the practicality of the carbon fiber cloth reinforcement of reinforced concrete beams.

[0026] In this embodiment, the side mounting plate 5 of the triangular support mechanism 4 is installed on the side of the fixed column 1 by the cooperation of the first mounting hole 8 and the first bolt 11.

[0027] For details, please refer to Figure 2 and Figure 4 The horizontal support plate 6 has multiple second mounting holes 9, and the inner cavity of each of the multiple second mounting holes 9 is fitted with a second bolt 10. The end of each second bolt 10 is threaded through the U-shaped carbon fiber cloth 3 and installed into the interior of the concrete beam 2.

[0028] In this embodiment, the horizontal support plate 6 at the top of the triangular support mechanism 4 is installed at the bottom of the concrete beam 2 through the cooperation of the second mounting hole 9 and the second bolt 10.

[0029] For details, please refer to Figure 1 The triangular support mechanism 4 is made of carbon fiber in one piece.

[0030] In this embodiment, a triangular support mechanism 4 is used to reinforce and support the fixed column 1 and the concrete beam 2. At the same time, the force on both ends of the concrete beam 2 is directly transmitted to the fixed column 1 through the triangular support mechanism 4, which plays the role of supporting and reinforcing both ends of the concrete beam 2.

Next, the first bolt 11 is inserted into the first mounting hole 8, so that the end of the first bolt 11 is threaded into the inside of the fixed column 1 to connect the side mounting plate 5 and the fixed column 1. Then, the second bolt 10 is inserted into the second mounting hole 9, so that the end of the second bolt 10 is threaded into the inside of the concrete beam 2 to connect the concrete beam 2 and the horizontal support plate 6. Finally, the U-shaped carbon fiber cloth 3 is used to reinforce the structure of the concrete beam 2, and the triangular support mechanism 4 on the side of the fixed column 1 supports the U-shaped carbon fiber cloth 3 and the concrete beam 2, ensuring the effect of supporting and reinforcing the concrete beam 2.
