Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete masonry reinforcement technology, and in particular to a novel reinforcement structure for concrete masonry. Background Technology
[0002] Concrete masonry is a widely used basic structural form in building engineering. Made primarily of concrete, it is produced through a rational mix design, casting, and curing process. It boasts advantages such as high strength, durability, moderate cost, and ease of construction, and is widely used in the main load-bearing systems of various projects, including industrial plants, civil buildings, bridges, and tunnels. Its core components include concrete columns and beams, which are interconnected to form a complete load-bearing system. This system bears the vertical loads and horizontal forces of the building structure, forming the core foundation for ensuring the overall stability and safety of the building.
[0003] As buildings age, concrete masonry structures face various adverse factors during long-term use. On one hand, the materials themselves undergo natural aging, such as concrete carbonization and steel corrosion, leading to a gradual decrease in component strength. On the other hand, urbanization processes, including increased loads and changes in usage functions, make it difficult for existing structures to meet new demands. Furthermore, defects in construction techniques and insufficient quality control in some early projects further exacerbate structural risks. These factors combined result in concrete columns, beams, and other components generally exhibiting insufficient strength, decreased stability, and weak seismic performance. This not only affects the normal use of buildings but also poses a serious threat to personal safety and property. Therefore, a new type of reinforced concrete masonry structure is urgently needed to specifically address these structural risks and improve the safety performance and service life of existing buildings. Utility Model Content
[0004] The main purpose of this utility model is to provide a new type of reinforcement structure for concrete masonry, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel reinforcement structure for concrete masonry includes a column reinforcement assembly and a beam reinforcement assembly. The column reinforcement assembly is fixedly fitted onto a concrete column, and the beam reinforcement assembly is fixedly fitted onto a concrete beam. The beam reinforcement assembly is fixedly connected to the column reinforcement assembly. The column reinforcement assembly consists of four main reinforcing angle steels arranged horizontally and symmetrically. There are several connecting reinforcing steel plates, each fixedly connected to two adjacent main reinforcing angle steels. The beam reinforcement assembly... The fixing assembly consists of a connecting reinforcement plate, a U-shaped support steel frame, a first diagonal brace, a second diagonal brace, and a mounting and fixing steel plate. There are two connecting reinforcement plates and two U-shaped support steel frames, which are symmetrically fixed at both ends of the two connecting reinforcement plates. There are four first diagonal braces and four second diagonal braces, which are fixedly connected to the connecting reinforcement plate and the U-shaped support steel frame, respectively. There are four mounting and fixing steel plates, which are symmetrically fixed at the upper ends of the two U-shaped support steel frames.
[0006] Preferably, the four main reinforcing angle steels on the column reinforcement assembly are respectively attached to the four corners of the concrete column, and the connecting reinforcing steel plate is fixedly installed on the end face of the concrete column by anchor bolts.
[0007] Preferably, the main reinforcing angle steel and the connecting reinforcing steel plate on the column reinforcement assembly are fixedly connected by welding.
[0008] Preferably, the connecting reinforcement plate, U-shaped support steel frame, and installation fixing steel plate on the beam reinforcement assembly are all fixedly installed on the end face of the concrete beam by anchor bolts, and the U-shaped support steel frame is sleeved on the lower part of the concrete beam.
[0009] Preferably, the connecting reinforcement plate, U-shaped support steel frame, first diagonal steel plate, second diagonal steel plate, and installation fixing steel plate on the beam reinforcement assembly are fixedly installed together by welding. The connecting reinforcement plate and U-shaped support steel frame are both fixedly connected to the upper part of the main reinforcement angle steel on the column reinforcement assembly by welding.
[0010] Compared with the prior art, the present invention has the following beneficial effects: By setting up a reinforcement structure consisting of column reinforcement components and beam reinforcement components, the column reinforcement components are composed of four horizontally symmetrical main reinforcement angle steels and several connecting reinforcement steel plates. The four main reinforcement angle steels are tightly attached to the four corners of the concrete column, and the connecting reinforcement steel plates are fixed to the end face of the concrete column with anchor bolts and welded to the adjacent main reinforcement angle steels, forming a stable frame reinforcement structure. This structure can comprehensively wrap and restrain the concrete column from all sides, effectively improving the compressive strength, lateral displacement resistance, and overall stability of the concrete column, and delaying the strength loss caused by concrete carbonization and steel corrosion. The beam reinforcement components adopt a combination design of connecting reinforcement plates, U-shaped support steel frames, first diagonal steel plates, second diagonal steel plates, and installation and fixing steel plates. Symmetrical steel frames are installed at both ends of the connecting reinforcement plate and fitted under the concrete beam. These frames, along with four first and four second diagonal bracing plates, form a multi-directional load-bearing support system. Anchor bolts secure each component to the end face of the concrete beam, significantly enhancing its bending and shear resistance and preventing cracking or deformation due to increased load or long-term use. Furthermore, the beam reinforcement components are firmly connected to the column reinforcement components via welding, creating a synergistic load-bearing structure that greatly improves the overall load-bearing capacity, seismic performance, and stability of the concrete masonry structure. This effectively compensates for early construction defects and structural hazards caused by long-term use, extends the building's service life, and ensures personal and property safety.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Please see Figure 1 - Figure 4 As shown, a novel reinforced concrete masonry structure includes a column reinforcement component 1 and a beam reinforcement component 2. The column reinforcement component 1 is fixedly fitted onto a concrete column 3, and the beam reinforcement component 2 is fixedly fitted onto a concrete beam 4. The beam reinforcement component 2 is fixedly connected to the column reinforcement component 1. The column reinforcement component 1 consists of four main reinforcing angle steels 5 and connecting reinforcing steel plates 6. There are four main reinforcing angle steels 5 arranged horizontally and symmetrically. There are several connecting reinforcing steel plates 6, and each connecting reinforcing steel plate 6 is fixedly connected to two adjacent main reinforcing angle steels 5. The beam reinforcement component 2 consists of... The system consists of a connecting and reinforcing plate 7, a U-shaped support steel frame 8, a first diagonal bracing steel plate 9, a second diagonal bracing steel plate 10, and an installation and fixing steel plate 11. There are two connecting and reinforcing plates 7 and two U-shaped support steel frames 8, which are symmetrically fixed at both ends of the two connecting and reinforcing plates 7. There are four first diagonal bracing steel plates 9 and four second diagonal bracing steel plates 10, which are fixedly connected to the connecting and reinforcing plates 7 and the U-shaped support steel frames 8, respectively. There are four installation and fixing steel plates 11, which are symmetrically fixed at the upper ends of the two U-shaped support steel frames 8.
[0015] Specifically, the four main reinforcing angle steels 5 on the column reinforcement component 1 are respectively attached to the four corners of the concrete column 3. The connecting reinforcing steel plates 6 are fixedly installed on the end face of the concrete column 3 by anchor bolts. The main reinforcing angle steels 5 and the connecting reinforcing steel plates 6 on the column reinforcement component 1 are fixedly connected by welding. By setting up a reinforcement structure composed of column reinforcement component 1 and beam reinforcement component 2, wherein the column reinforcement component 1 is composed of four horizontally symmetrical main reinforcing angle steels 5 and several connecting reinforcing steel plates 6, the four main reinforcing angle steels 5 are attached to the four corners of the concrete column 3, and the connecting reinforcing steel plates 6 are fixed to the end face of the concrete column 3 by anchor bolts and welded to the adjacent main reinforcing angle steels 5, a stable frame reinforcement structure is formed, which can wrap and constrain the concrete column 3 from all sides, effectively improving the compressive strength, lateral displacement resistance and overall stability of the concrete column 3, and delaying the strength reduction caused by concrete carbonization and steel corrosion.
[0016] Specifically, the connecting reinforcement plate 7, U-shaped support steel frame 8, and installation fixing steel plate 11 on the beam reinforcement component 2 are all fixedly installed on the end face of the concrete beam 4 by anchor bolts. The U-shaped support steel frame 8 is sleeved on the lower part of the concrete beam 4. The connecting reinforcement plate 7, U-shaped support steel frame 8, first diagonal steel plate 9, second diagonal steel plate 10, and installation fixing steel plate 11 on the beam reinforcement component 2 are fixedly installed together by welding. The connecting reinforcement plate 7 and U-shaped support steel frame 8 are both fixedly connected to the upper part of the main reinforcement angle steel 5 on the column reinforcement component 1 by welding. The beam reinforcement component 2 adopts a combination design of connecting reinforcement plate 7, U-shaped support steel frame 8, first diagonal steel plate 9, second diagonal steel plate 10, and installation fixing steel plate 11. The two U-shaped support steel frames 8 are symmetrically installed on the end face of the concrete beam 4. The reinforcing plate 7 is connected to both ends and fitted onto the lower part of the concrete beam 4. It is fixed by the diagonal bracing of four first diagonal steel plates 9 and four second diagonal steel plates 10, forming a multi-directional force support system. At the same time, the components are fixed to the end face of the concrete beam 4 by anchor bolts, which significantly enhances the bending and shear resistance of the concrete beam 4 and prevents cracking and deformation of the concrete beam 4 due to load upgrades or long-term use. Furthermore, the beam reinforcement component 2 and the column reinforcement component 1 are firmly connected by welding, so that the concrete column 3 and the concrete beam 4 form a whole structure that works together to bear the load. This greatly improves the overall load-bearing capacity, seismic performance and stability of the concrete masonry structure, effectively makes up for early construction defects and structural hazards caused by long-term use, extends the service life of the building and protects personal and property safety.
[0017] It should be noted that the height of the column reinforcement component 1 is perfectly matched with the height of the concrete column 3. That is, the column reinforcement component 1 extends from the bottom to the top of the concrete column 3, ensuring that the four main reinforcement angle steels 5 and several connecting reinforcement steel plates 6 can uniformly wrap and constrain the entire height range of the concrete column 3. This avoids the problem of local stress concentration or inconsistent reinforcement effect due to insufficient reinforcement height, and fully utilizes the enhancement effect of the frame reinforcement structure on the overall compressive and lateral resistance of the concrete column 3. The length of the beam reinforcement component 2 is matched with the length of the concrete beam 4, so that the connecting reinforcement plate 7, U-shaped support steel frame 8, first diagonal steel plate 9, second diagonal steel plate 10 and installation fixing steel plate 11 can fully cover the main stress area of the concrete beam 4. This ensures that when the beam is subjected to vertical loads and horizontal forces, the reinforcement component can evenly distribute the stress, avoiding local weakness due to insufficient reinforcement length, and thus ensuring the improvement of the overall bending and shear resistance of the concrete beam 4.
