Abstract
Description
Technical Field
[0001] This utility model relates to the field of reinforced concrete technology, specifically a reinforcement device for connection nodes in reinforced concrete structures. Background Technology
[0002] Reinforced concrete frame structures are structural systems composed of beams, slabs, columns, and other components connected at joints to withstand vertical and horizontal loads. They are widely used in building construction. Their working principle is as follows: under vertical loads, the load on the slab is transferred to the columns through the beams, and then from the columns to the foundation. Under horizontal loads (such as wind and earthquakes), the frame structure composed of beams and columns resists horizontal forces through its own lateral stiffness, maintaining structural stability. Furthermore, reinforced concrete frame structures offer flexible spatial arrangement, allowing for space partitioning according to usage requirements; they have good overall integrity and seismic performance; and construction is relatively simple, employing prefabrication or cast-in-place methods. They are suitable for multi-story and high-rise buildings, such as office buildings, educational buildings, shopping malls, and residences. Generally, reinforced concrete frame structures are more economical and reasonable for buildings under 10 stories, but with the development of building technology and the adoption of strengthening measures, frame structures can also be used for taller buildings.
[0003] The joints of reinforced concrete frame structures are not only where the upper and lower frame columns and frame beams intersect and connect, but also key points for the seismic fortification of the building structure. Damage to these joints often leads to the continuous collapse of the entire frame structure, with very serious consequences. Therefore, it is essential to take certain reinforcement measures for frame beam-column joints with potential safety hazards. However, most existing reinforcement devices are used individually and lack flexibility. In actual engineering, due to the different dimensions and other conditions of the connection joints, it is difficult for a single fixed-specification reinforcement device to adapt to the actual situation, while multiple independent reinforcement devices are difficult to work together to form an effective overall reinforcement effect.
[0004] Therefore, this utility model provides a reinforcement device for the connection nodes of reinforced concrete structures to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a reinforcement device for connection nodes in reinforced concrete structures, which solves the aforementioned problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforced concrete structure connection node reinforcement device, comprising a reinforced concrete column and a reinforced concrete beam. An L-shaped steel plate is provided on the right outer wall of the reinforced concrete column. The top of the L-shaped steel plate contacts the bottom of the reinforced concrete beam. Two sets of first screws are horizontally threaded through the bottom right end of the L-shaped steel plate and connected to the reinforced concrete column through the two sets of first screws. Two sets of second screws are vertically threaded through the right top of the L-shaped steel plate and connected to the reinforced concrete beam through the two sets of second screws. An L-shaped slot is provided on the front outer wall of the L-shaped steel plate. An L-shaped insert plate matching the L-shaped slot is fixedly installed on the rear outer wall of the L-shaped steel plate. Several sets of third screws are threadedly connected to the L-shaped steel plate at the L-shaped slot position. Matching mounting holes are provided on the L-shaped insert plate at the corresponding positions of each set of third screws.
[0007] Preferably, each set of mounting holes has an internal thread on its inner wall that matches the third screw.
[0008] Preferably, a sealing gasket is fixedly installed on the inner wall of the L-shaped slot.
[0009] Preferably, a reinforcing block is fixedly installed at the corner of the L-shaped steel plate, and the cross-section of the reinforcing block is an isosceles triangle.
[0010] Preferably, two sets of reinforcing rods are fixedly installed at an angle on the L-shaped steel plate.
[0011] Preferably, the L-shaped steel plate is coated with an anti-corrosion layer and a fireproof layer, and the protective layer is located outside the anti-corrosion layer.
[0012] Preferably, the anti-corrosion layer is made of epoxy resin, and the fireproof layer is made of a mixture of perlite, cement, and glass fiber.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1:
[0022] Please see Figure 1-3 A reinforcement device for connecting joints in reinforced concrete structures includes a reinforced concrete column 1 and a reinforced concrete beam 2. An L-shaped steel plate 3 is installed on the outer right side of the reinforced concrete column 1. The top end of the L-shaped steel plate 3 contacts the bottom end of the reinforced concrete beam 2. Two sets of first screws 4 are horizontally threaded through the bottom right side of the L-shaped steel plate 3 and connected to the reinforced concrete column 1 via the two sets of first screws 4. Two sets of second screws 401 are vertically threaded through the right side of the top end of the L-shaped steel plate 3 and connected via the two sets of second screws 401. 1. Connected to the reinforced concrete beam 2, the L-shaped steel plate 3 has an L-shaped slot 5 on its front outer wall, and an L-shaped insert plate 7 that matches the L-shaped slot 5 is fixedly installed on the rear outer wall of the L-shaped steel plate 3. Several sets of third screws 6 are threadedly connected to the L-shaped steel plate 3 at the position of the L-shaped slot 5. The L-shaped insert plate 7 has a matching mounting hole 8 at the corresponding position of each set of third screws 6. The inner wall of each set of mounting holes 8 has an internal thread that matches the third screw 6. A sealing gasket is fixedly installed on the inner wall of the L-shaped slot 5.
[0023] When using this device, the installer first assembles two or more L-shaped steel plates 3 using the L-shaped slots 5 and L-shaped inserts 7 according to the actual installation situation. Then, the third screw 6 is rotated to connect them, allowing the installer to adjust the width of the reinforcement components according to the actual installation situation. This ensures a good fit to the actual installation and guarantees the stability of the connection between multiple reinforcement devices, thus forming an effective overall reinforcement effect. After assembly, the installer can connect it to the reinforced concrete column 1 and the reinforced concrete beam respectively using the first screw 4 and the second screw 401. In addition, the sealing gasket fixedly installed on the inner wall of the L-shaped slot 5 makes the insertion of the L-shaped insert 7 into the L-shaped slot 5 more precise and stable.
[0024] Example 2:
[0025] Please see Figure 1-3 This embodiment provides a technical solution based on embodiment one: a reinforcing block 9 is fixedly installed at the corner of the L-shaped steel plate 3, and the cross-section of the reinforcing block 9 is an isosceles triangle; two sets of reinforcing rods 10 are fixedly installed obliquely on the L-shaped steel plate 3; the L-shaped steel plate 3 is coated with an anti-corrosion layer and a fireproof layer, and the protective layer is located outside the anti-corrosion layer; the anti-corrosion layer is made of epoxy resin, and the fireproof layer is made of a mixture of perlite, cement and glass fiber.
[0026] In this device, the reinforcement blocks 9 and reinforcing rods 10 enhance its strength. Furthermore, the epoxy resin anti-corrosion layer, with its excellent adhesion and flexibility, firmly adheres to the surface of the L-shaped steel plate 3 and resists external wear and impact to a certain extent. Simultaneously, the fireproof layer, made of a mixture of perlite, cement, and glass fiber, is coated outside the anti-corrosion layer. This fireproof layer possesses excellent thermal insulation properties, effectively blocking heat transfer and slowing the temperature rise of the steel structure in a fire. Being an inorganic material, it is chemically stable and does not readily react with the anti-corrosion layer, thus protecting it. Moreover, its cost is relatively low. These features enhance the practicality of this device.
