Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete structure technology, specifically to a reinforcement structure for the core area of a reinforced concrete beam-column joint. Background Technology
[0002] Currently, conventional reinforced concrete structures often fail to meet design requirements after changes in use, prolonged disrepair, or earthquake damage. Beam-column joints are often the weakest points, and since they are crucial to the entire structure, their seismic performance needs to be strengthened. Existing methods for reinforcing beam-column joints in reinforced concrete structures involve directly increasing the amount of concrete at the joint. However, this method requires formwork and wet concrete work, which is not only cumbersome and difficult to implement, but also time-consuming. Therefore, we propose a core reinforcement structure for reinforced concrete beam-column joints. Utility Model Content
[0003] The present invention aims to provide a core reinforcement structure for reinforced concrete beam-column joints, which can effectively enhance the bending stiffness and overall strength between the column and the beam.
[0004] Therefore, the technical solution adopted by this utility model is as follows:
[0005] The core area reinforcement structure for reinforced concrete beam-column joints includes:
[0006] A column, on which a crossbeam is installed, and a reinforcing plate assembly is fixedly connected between the column and the crossbeam. The reinforcing plate assembly is bent, and a reinforcing block is fixedly connected to the bent part.
[0007] The slot is formed on the side wall of the reinforcing plate assembly. A limiting groove is formed on the inner wall of the slot, and a locking part adapted to the slot is formed on the side wall of the crossbeam. Limiting strips adapted to the limiting groove are fixedly connected to both sides of the locking part.
[0008] Tie bolts, which are detachably fixed between the reinforcing plate assembly and the crossbeam.
[0009] Based on the above technical solution, its operating principle and the resulting technical effects are as follows:
[0010] When installing the column and beam, firstly, the second plate is inserted into the engagement part of the beam through the limiting groove, ensuring that the limiting groove is engaged with the limiting strip. This ensures that the position of the reinforcing plate assembly and the beam is relatively fixed, preventing relative movement under stress. Then, the tie bolts are passed through the mounting holes for fixing, effectively securing the reinforcing plate assembly to the beam. In actual use, the reinforcing plate assembly enhances the load-bearing capacity and bending stiffness between the column and beam, improving the overall structural stability. Furthermore, the reinforcing blocks help to distribute the force or stress more evenly to other parts of the reinforcing plate assembly, reducing local stress concentration and improving the overall stability and strength of the structure. Finally, the end of the beam is installed and fixed to the side wall of the column.
[0011] In a preferred embodiment, the present invention can be further configured such that the reinforcing plate assembly includes a first plate and a second plate, the first plate and the second plate being integrally formed and perpendicular to each other.
[0012] In a preferred embodiment, the present invention can be further configured such that the cross-sectional shape of the reinforcing block is fan-shaped, and the reinforcing block is located at the connection between the first plate and the second plate.
[0013] In a preferred embodiment, the present invention can be further configured such that the number of reinforcing plate assemblies is four, and every two reinforcing plate assemblies are used in combination.
[0014] In a preferred embodiment, the present invention can be further configured such that the slot is formed on the bottom side wall of the second plate.
[0015] In a preferred embodiment, the present invention can be further configured such that the cross-sectional shape of the limiting strip is trapezoidal, and every two limiting strips are used in combination.
[0016] In a preferred embodiment, the present invention can be further configured such that the first plate is fixed to the column by high-strength bolts.
[0017] In a preferred embodiment, the present invention can be further configured such that mounting holes adapted to tie bolts are provided on the side walls of both the crossbeam and the second plate.
[0018] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:
[0019] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.
[0020] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.
[0021] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.
[0022] A movable connection refers to a connection in which parts or components are fixed but have relative motion.
[0023] The above-mentioned technical solution of this utility model has the following beneficial technical effects:
[0024] 1. In this utility model, the reinforced plate assembly effectively fixes the beam and column, which can enhance the load-bearing capacity and bending stiffness between the column and beam, and the installation process is simpler and faster, reducing construction difficulty and time, and improving project efficiency.
[0025] 2. In this utility model, the fan-shaped reinforcing blocks not only help to distribute the force or stress received more evenly to other parts of the reinforcing plate assembly, which helps to reduce local stress concentration and improve the overall stability and strength of the structure, but also increase the stiffness of the reinforcing plate assembly when bending and under stress, thereby improving the overall performance of the structure.

[0031] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features in the embodiments can be combined with each other.
[0032] Based on the concept of this application, combined with Figures 1 to 3 This document describes an embodiment of a reinforced concrete beam-column joint core area reinforcement structure for strengthening the connection between a column 1 and a beam 2. Specifically, this reinforced concrete beam-column joint core area reinforcement structure is constructed as a split structure, comprising three components: a column 1, a slot 5, and tie bolts 9. The beam 2 and column 1 are reinforced by a reinforcing plate assembly 3.
[0033] Effective fixation enhances the load-bearing capacity and bending stiffness between column 1 and beam 2, and the installation process is simpler and faster, reducing construction difficulty and time, and improving project efficiency. Furthermore, the fan-shaped reinforcing blocks 4 not only help to distribute the force or stress received more evenly to other parts of the reinforcing plate assembly 3, which helps to reduce local stress concentration and improve the overall stability and strength of the structure, but also increase the stiffness of the reinforcing plate assembly 3 under bending and stress.
[0034] Combination Figures 1-3 As shown, the reinforced concrete beam-column joint core area reinforcement structure provided by this utility model includes:
[0035] Column 1, a crossbeam 2 is installed on the side wall of column 1, and a reinforcing plate assembly 3 is fixedly connected between column 1 and crossbeam 2. The reinforcing plate assembly 3 is set in a bent shape, and a reinforcing block 4 is fixedly connected to the bent part.
[0036] The slot 5 is formed on the side wall of the reinforcing plate assembly 3. The inner wall of the slot 5 is provided with a limiting groove 6, and the side wall of the crossbeam 2 is provided with a locking part 7 that matches the slot 5. The two sides of the locking part 7 are fixedly connected with limiting strips 8 that match the limiting groove 6.
[0037] Tie bolt 9 is detachably fixed between the reinforcing plate assembly 3 and the crossbeam 2.
[0038] Regarding the technical solution of this embodiment, the reinforcing plate assembly 3 includes a first plate 31 and a second plate 32. The first plate 31 and the second plate 32 are integrally formed and perpendicular to each other. The first plate 31 is fixed to the column 1 by high-strength bolts 10. The slot 5 is opened on the bottom side wall of the second plate 32. In actual use, the reinforcing plate assembly 3 is first installed on the crossbeam 2 using the slot 5 and the engaging part 7. Then, the reinforcing plate assembly 3 and the crossbeam 2 are fixed using tie bolts 9. When the crossbeam 2 is subjected to external force, the reinforcing plate assembly 3 can enhance the connection strength between the column 1 and the crossbeam 2 and prevent bending and collapse.
[0039] Furthermore, mounting holes 11 adapted to tie bolts 9 are provided on the side walls of both the crossbeam 2 and the second plate 32. The mounting holes 11 facilitate the fixing of tie bolts 9. There are four tie bolts 9, and each pair of tie bolts 9 are used together.
[0040] The reinforcing block 4 is mainly used to enhance the connection strength between the first plate 31 and the second plate 32, and to prevent the first plate 31 and the second plate 32 from bending and being damaged, which would lead to the collapse of the column 1 and the beam 2. In this embodiment, the reinforcing block 4 has a fan-shaped cross-section and is located at the connection between the first plate 31 and the second plate 32. The fan-shaped reinforcing block 4 can not only help to distribute the force or stress received more evenly to other parts of the reinforcing plate assembly 3, which helps to reduce local stress concentration and improve the overall stability and strength of the structure, but also increase the stiffness of the reinforcing plate assembly 3 when bending and under stress, thereby improving the overall performance of the structure.
[0041] Regarding the technical solution of this embodiment, there are four reinforcing plate assemblies 3. Every two reinforcing plate assemblies 3 are used together as a group. Reinforcing plate assemblies 3 are installed on the upper and lower sides of a crossbeam 2, which can effectively increase the load-bearing area of the crossbeam 2, thereby improving the load-bearing capacity and bending stiffness of the overall structure.
[0042] Regarding the technical solution of this embodiment, the cross-sectional shape of the limiting strip 8 is trapezoidal, and every two limiting strips 8 are used in pairs. By using the limiting strips 8 and the limiting grooves 6, it is possible not only to ensure that the positions of the reinforcing plate assembly 3 and the crossbeam 2 are relatively fixed and to prevent them from moving relative to each other when under stress, but also to effectively increase the contact area between them and increase the stress area, thereby increasing the load-bearing capacity and bending stiffness of the structure. At the same time, the installation between the reinforcing plate assembly 3 and the crossbeam 2 is simpler and faster, reducing construction difficulty and time, and improving project efficiency.
[0043] Specifically, when it is necessary to install the column 1 and the beam 2, firstly, the second plate 32 is clamped into the engaging part 7 of the beam 2 through the limiting groove 6, and the limiting groove 6 is engaged into the limiting strip 8. This ensures that the position between the reinforcing plate assembly 3 and the beam 2 is relatively fixed, preventing them from moving relative to each other when under stress. Then, the tie bolt 9 is passed through the mounting hole 11 and fixed, so that the reinforcing plate assembly 3 and the beam 2 are effectively fixed. In actual use, the reinforcing plate assembly 3 can enhance the load-bearing capacity and bending stiffness between the column 1 and the beam 2, and can enhance the stability of the overall structure. In addition, the reinforcing block 4 can also help to distribute the force or stress more evenly to other parts of the reinforcing plate assembly 3, which helps to reduce local stress concentration and improve the overall stability and strength of the structure. Then, the end of the beam 2 and the first plate 31 are installed and fixed on the side wall of the column 1.
[0044] The reinforced concrete beam-column joint core area reinforcement structure provided by this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0045] The core area reinforcement structure for reinforced concrete beam-column joints includes:
[0046] Column 1, a crossbeam 2 is installed on the side wall of column 1, and a reinforcing plate assembly 3 is fixedly connected between column 1 and crossbeam 2. The reinforcing plate assembly 3 is set in a bent shape, and a reinforcing block 4 is fixedly connected to the bent part.
[0047] The slot 5 is formed on the side wall of the reinforcing plate assembly 3. The inner wall of the slot 5 is provided with a limiting groove 6, and the side wall of the crossbeam 2 is provided with a locking part 7 that matches the slot 5. The two sides of the locking part 7 are fixedly connected with limiting strips 8 that match the limiting groove 6.
[0048] Tie bolt 9 is detachably fixed between the reinforcing plate assembly 3 and the crossbeam 2.
[0049] The working principle and usage process of this utility model are as follows: When it is necessary to install the column 1 and the crossbeam 2, firstly, the second plate 32 is clamped into the engaging part 7 of the crossbeam 2 through the limiting groove 6, and the limiting groove 6 is engaged into the limiting strip 8, so as to ensure that the position between the reinforcing plate assembly 3 and the crossbeam 2 is relatively fixed and to prevent them from moving relative to each other when subjected to force. Then, the tie bolt 9 is passed through the mounting hole 11 and fixed, so that the reinforcing plate assembly 3 and the crossbeam 2 are effectively fixed. In actual use, the reinforcing plate assembly 3 can enhance the load-bearing capacity and bending stiffness between the column 1 and the crossbeam 2, and can enhance the stability of the overall structure. In addition, the reinforcing block 4 can also help to transmit the force or stress received more evenly to other parts of the reinforcing plate assembly 3, which helps to reduce local stress concentration and improve the overall stability and strength of the structure. Then, the end of the crossbeam 2 and the first plate 31 are installed and fixed on the side wall of the column 1.
