Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building structure reinforcement, in particular to a steel-clad reinforcement frame column top anchoring structure. Background Art
[0002] As key load-bearing components in building structures, frame columns require reinforcement technology that is crucial for improving a building's stability and safety. Concrete structures are widely used in multi-story, high-rise buildings, and those with high seismic requirements due to their excellent load-bearing capacity and cost-effectiveness. However, over time, concrete structures gradually age, developing cracks, corrosion, and other problems that affect the safety and service life of the structure. Similarly, with factors such as renovation requirements, changes in usage functions, and increased seismic fortification intensity in the area where the building is located, such frame structures require reinforcement. Traditional reinforcement methods have limitations: methods such as increasing the cross-section, carbon fiber reinforcement, and prestressed reinforcement can improve the structure's load-bearing capacity to a certain extent, but they also come with long construction periods and significant weight increases in wet working structures. Furthermore, when reinforcing existing frame structures with steel-clad frame columns, when the structure is reinforced to the top of the column, the angle steel is often extended to the bottom of the slab, making it difficult to effectively anchor the longitudinal reinforcement angle steel. Utility Model Content
[0003] The purpose of this utility model is to provide a steel-clad reinforced frame column top anchoring structure. This structure extends the longitudinal reinforcement angle steel upward from the steel-clad reinforced column top, passing through the floor panel to form an anchoring section at the floor, or passing through the roof panel to form an anchoring end at the roof. The reinforced longitudinal angle steel is anchored to this anchoring section (or anchoring end). This solves the problem of the difficulty in effectively anchoring the steel-clad reinforced longitudinal angle steel, facilitates seismic reinforcement of the frame column, and transmits bending moments. This solves the problems raised in the aforementioned background art.
[0004] The technical solutions adopted in this utility model are as follows:
[0005] A steel-clad reinforced frame column top anchoring structure includes a frame column 6 and a frame beam 7. A reinforcing angle steel 1 is provided at each column corner of the frame column 6. Two adjacent reinforcing angle steels 1 are connected by a number of steel gusset plates 2. The reinforcing angle steel 1 passes through the floor panel or roof panel together with the frame column 6. A through screw 3 is provided at the root of the frame beam at the node area between the frame beam 7 and the frame column 6. The through screw 3 passes through the root of the frame beam 7, and the end of the through screw 3 is lap-welded on the reinforcing angle steel 1 for connecting and fixing the reinforcing angle steel 1.
[0006] The reinforcing angle steel 1 is attached to the four column corners of the frame column 6 and connected to the column corners of the frame column 6 by bonding steel.
[0007] The two ends of the steel gusset plate 2 are lap welded or butt welded to two adjacent reinforcing angle steels 1 .
[0008] The reinforcement angle steels 1 pass through the floor panel together with the frame columns 6 to form an anchoring section on the upper portion of the floor panel. A plurality of steel tie plates 2 are arranged between adjacent reinforcement angle steels 1 on the anchoring section.
[0009] When the reinforcing angle steel 1 passes through the roof panel together with the frame column 6, an anchoring end is formed at the top of the frame column. A roof anchoring steel plate 4 is provided on the top of the anchoring end. The roof anchoring steel plate 4 is fixed to the top of the frame column 6 by an anchor bolt 5, and the roof anchoring steel plate 4 is close to the top of the roof panel. At the same time, the roof anchoring steel plate 4 is located on the inner side of the reinforcing angle steel 1 and is welded to the reinforcing angle steel 1. After welding, liquid steel adhesive is poured into the gap between the roof anchoring steel plate 4 and the concrete at the top of the column.
[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0011] The utility model has the advantages of simple construction, simple structure, safe and reliable reinforcement method, good reinforcement effect and convenient design. By extending the reinforcement angle steel through the floor (roof) plate at the top of the steel-clad reinforced frame column, a certain anchoring structure is formed above the floor or the top of the roof, ensuring that the longitudinal reinforcement angle steel of the steel-clad reinforced frame column can be effectively anchored at the top of the column, solving the problem that the longitudinal reinforcement angle steel of the steel-clad reinforced frame column is difficult to effectively anchor, ensuring the transmission of the bending moment of the frame column reinforcement column top, and also achieving the effect of strong column and weak beam.

[0021] Example 1
[0022] like Figure 1-5 The present embodiment provides a steel-clad reinforced frame column top anchoring structure, including a frame column 6 and a frame beam 7. A reinforcing angle steel 1 is provided at each column corner of the frame column 6. Two adjacent reinforcing angle steels 1 are connected by a plurality of steel tie plates 2. The reinforcing angle steel 1 passes through the floor panel or roof panel together with the frame column 6. A through screw 3 is provided at the node area between the frame beam 7 and the frame column 6. The through screw 3 passes through the root of the frame beam 7, and the end of the through screw 3 is lap-welded on the reinforcing angle steel 1. The through screw 3 is used to connect and fix the reinforcing angle steel 1 like the steel tie plate 2.
[0023] The reinforcement angle steel 1 is attached to the column corner of the frame column 6 and connected to the concrete by bonding. The two ends of the steel gusset plate 2 are lap welded or butt welded to two adjacent reinforcement angle steels 1.
[0024] like Figure 1-3 As shown, the reinforcing angle steel 1 passes through the roof panel together with the frame column 6, and a roof anchor steel plate 4 is provided on the top of the anchoring end. The roof anchor steel plate 4 is fixed to the top of the frame column 6 by anchor bolts. At the same time, the roof anchor steel plate 4 is located on the inner side of the reinforcing angle steel 1 and is welded to the reinforcing angle steel 1. After welding, liquid steel adhesive is poured into the gap between the roof anchor steel plate 4 and the column top concrete.
[0025] The length of the anchor end protruding from the roof above the roof is determined only according to the length requirement of the welding between the roof anchor steel plate and the reinforcing angle steel.
[0026] The construction process of the anchoring end at the roof panel includes removing the original roof waterproof insulation layer to the original structural layer at the roof, and then continuing to make a new roof anchor steel plate at the roof according to the inner edge size of the steel-clad reinforced angle steel, anchoring the roof anchor steel plate to the roof through anchor bolts, and then welding the reinforced angle steel to the roof anchor plate to achieve the anchoring of the reinforced angle steel at the roof (anchoring end), and then restore the roof after reinforcement.
[0027] like Figure 4-5 As shown, the reinforcement angle steel 1 passes through the floor panel together with the frame column 6 to form an anchoring end at the upper part of the floor panel. A plurality of steel tie plates 2 are arranged between adjacent reinforcement angle steels 1 on the anchoring section.
[0028] The construction process of the anchoring section at the floor panel includes drilling a hole through the floor panel, passing the reinforcement angle steel through, and then continuing to extend the steel reinforcement for a certain anchoring length (anchoring section) on the floor net, so as to reliably anchor the reinforcement angle steel.
[0029] In the present invention, the upper end of the reinforcing angle steel 1 is cut through the beam-column node area when necessary, and a hole is drilled through the floor (roof) panel, and then extended to the top of the horizontal structural plate. A plurality of longitudinally outsourced reinforcing angle steels 1 are fixedly connected with a plurality of middle-section reinforcing steel gusset plates 2 from bottom to top. A through-screw 3 is provided in the beam-column node range to connect with the reinforcing angle steel 1, which plays the same role as the rigid gusset plate, except that it needs to pass through the root of the frame beam; by extending the reinforced surface layer of the frame column top and the longitudinal outsourced reinforcing angle steel upward, an anchoring section or anchoring end is formed on the upper part of the horizontal structural plate, and then the reinforced longitudinal reinforcing angle steel is anchored to this anchoring section or anchoring end, thereby solving the problem that it is difficult to effectively anchor the outsourced reinforcing angle steel at the top of the column, and the extended longitudinal reinforcing angle steel anchoring section or anchoring end is also conducive to improving the seismic performance of the reinforced frame column.
[0030] The utility model has the advantages of simple construction, practical reinforcement scheme, relatively simple operation, good reinforcement effect, and can effectively solve the problem of insufficient anchoring of the angle steel column top of the frame column reinforced with steel cladding.
