Description

Technical Field

[0001] This utility model belongs to the field of building reinforcement technology, and in particular relates to a reinforcement structure for balconies in old residential areas with shock absorption function. Background Technology

[0002] Due to their age, balconies in many older residential buildings are showing signs of structural aging. As cantilever structures, balconies bear the weight of their own bodies, the activities of people, and external environmental factors over a long period, making their structural safety increasingly a concern.

[0003] Currently, traditional reinforcement methods mostly use external steel plates or carbon fiber cloth, which only improve static strength but cannot dissipate seismic energy. They are easily damaged during earthquakes. In addition, traditional reinforcement methods are complex to construct and often require a long construction period, causing great inconvenience to residents. Utility Model Content

[0004] In view of this, the present invention aims to propose a reinforcement structure for balconies in old residential areas with shock absorption function, in order to solve the problems that traditional reinforcement methods mostly use external steel plates or carbon fiber cloth, which only improve static strength but cannot dissipate seismic energy and are easily damaged during earthquakes. In addition, traditional reinforcement methods are complicated to construct and often require a long construction period, which brings great inconvenience to residents' lives.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides a reinforcement structure for balconies in old residential areas with shock absorption function, including a steel structure balcony main frame, a balcony panel, and a shock absorption structure. A U-shaped groove is welded onto the steel structure balcony main frame, and the balcony panel is fixed to the U-shaped groove. The shock absorption structure is connected to the four corners of the balcony panel. In the shock absorption structure, an upper connecting plate is connected to the balcony panel and a first connecting folding plate via a first connecting bolt. The first connecting folding plate and a second connecting folding plate are connected via a second connecting bolt. The second connecting folding plate is welded to a lower connecting plate. Shock-absorbing springs are located within spring connectors, and the spring connectors are respectively fixed to the lower surface of the upper connecting plate and the upper surface of the lower connecting plate.

[0007] Furthermore, the main frame of the steel structure balcony includes top-mounted square steel, connecting angle steel, bottom-mounted angle steel, and side-reinforcing angle steel. The top-mounted square steel is connected to the bottom-mounted angle steel via the connecting angle steel. The side-reinforcing angle steel is inclinedly installed at the side structural frame formed by the top-mounted square steel and the bottom-mounted angle steel. The bottom of the side-reinforcing angle steel is located at the angle where it connects to the front frame of the side structural frame. The top-mounted square steel and the bottom-mounted angle steel form a three-sided enclosure structure. The bottom-mounted angle steel has a U-shaped groove welded inside, and the connecting angle steel connected to the wall column has a side wall positioning hole.

[0008] Furthermore, the connecting angle steel is connected to the wall column via a side-wall metal expansion tube with a serrated edge.

[0009] Furthermore, the connecting angle steel at the top of the side reinforcing angle steel is fixed to the wall column and is a certain distance away from the square steel installed at the top.

[0010] Furthermore, the diameter of the shock-absorbing spring is 12mm.

[0011] Compared with existing technologies, the balcony reinforcement structure with shock absorption function in old residential areas described in this utility model has the following advantages:

[0012] In this utility model, square steel at the top, connecting angle steel, angle steel at the bottom, and reinforcing angle steel on the sides form a stable frame structure, improving the overall load-bearing capacity of the balcony. Square steel is used at the top to provide better bending resistance, while L-shaped angle steel is used for the connecting angle steel, bottom angle steel, and side reinforcing angle steel to enhance the stability of the connection with the balcony.

[0013] This utility model reinforces balconies in older residential communities by installing a steel structure main frame, thereby improving the balconies' load-bearing capacity. Simultaneously, the included shock-absorbing structure buffers and reduces damage to the balcony under external forces such as earthquakes. The steel structure in this solution is lightweight yet sturdy, providing sufficient reinforcement without excessively increasing the balcony's weight. The four-corner shock-absorbing design is easy to install, allowing for quick construction and minimizing disruption to residents' daily lives. Attached Figure Description

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] See Figures 1-2As shown, this embodiment provides a reinforcement structure for balconies in old residential areas with shock absorption function, including a steel structure balcony main frame, a balcony panel 2, and a shock absorption structure 7. A U-shaped groove is welded on the steel structure balcony main frame, and the balcony panel 2 is fixed at the U-shaped groove. The shock absorption structure 7 is connected to the four corners of the balcony panel 2. In the shock absorption structure, the upper connecting plate 8 is connected to the balcony panel 2 and the first connecting folding plate 9 by the first connecting bolt 12. The first connecting folding plate 9 and the second connecting folding plate 10 are connected by the second connecting bolt 13. The second connecting folding plate 10 is welded to the lower connecting plate 11. The shock absorption spring 15 is located in the spring connecting member 14, and the spring connecting member 14 is fixed to the lower surface of the upper connecting plate 8 and the upper surface of the lower connecting plate 11, respectively.

[0025] Specifically, in this embodiment, the main frame of the steel structure balcony includes a top-mounted square steel 3, a connecting angle steel 5, a bottom-mounted angle steel 6, and a side-reinforcing angle steel 4. The top-mounted square steel 3 is connected to the bottom-mounted angle steel 6 via the connecting angle steel 5. The side-reinforcing angle steel 4 is inclinedly installed at the side structural frame formed by the top-mounted square steel 3 and the bottom-mounted angle steel 6. The bottom of the side-reinforcing angle steel 4 is located at the angle where it connects to the front frame of the side structural frame. The top-mounted square steel 3 and the bottom-mounted angle steel 5 form a three-sided enclosing structure. The bottom-mounted angle steel 6 has a U-shaped groove welded inside. The connecting angle steel 5, which is connected to the wall column 1, has a side wall positioning hole.

[0026] A stable frame structure is formed by installing square steel at the top, connecting angle steel, angle steel at the bottom, and reinforcing angle steel on the sides, improving the overall load-bearing capacity of the balcony. Square steel is used at the top to provide better bending resistance, while L-shaped angle steel is used for the connecting angle steel, bottom angle steel, and side reinforcing angle steel to enhance the stability of the connection with the balcony.

[0027] Specifically, in this embodiment, the connecting angle steel 5 is connected to the wall column 1 through the side wall metal expansion tube sawtooth wall.

[0028] Specifically, in this embodiment, the connecting angle steel 5, which is connected to the top of the side reinforcing angle steel 4 and the wall column 1, is fixed and is a certain distance away from the top installed square steel 3.

[0029] Specifically, in this embodiment, the diameter of the shock-absorbing spring 15 is 12mm.

[0030] Balcony slabs bear loads from various directions during use, such as vertical loads from people's activities and the placement of objects, as well as horizontal loads like wind loads and seismic forces. Connecting damping structures to the four corners of the balcony slab allows these loads to be distributed more evenly throughout the entire structural system. During an earthquake, the complex forces generated by seismic waves can be transmitted and dispersed through the damping structures at the four corners, preventing excessive localized stress on the balcony slab and thus effectively improving the overall stability of the balcony under complex stress conditions.

[0031] Fabrication of steel structure balcony main frame assembly components: (1) Precast component cutting: This process is the material inspection part, which includes the confirmation of the model and specifications selected for the project and the quality inspection of the materials; (2) Layout and cutting: When laying out and marking, clearly mark the assembly marks, screw hole markings, the position and direction of the reinforcing plate, the tilt mark and the center line, the baseline and the inspection line, and make templates if necessary. Before marking, the bending and deformation of the materials should be corrected; (3) Cutting: The sheared or cut surface of the angle steel should be free of cracks, slag inclusions and delamination; (4) Assembly and forming: Before assembly, the angle steel should be corrected to meet the control deviation range, and the contact surface should be free of burrs, dirt and debris to ensure that the components are tightly assembled and meet the quality standards. When assembling, there should be a suitable amount of tools and equipment, such as right angle steel rulers, to ensure sufficient accuracy after assembly; (5) Welding: After welding, the rust, burrs and dirt in the 30-50mm range of the edge must be cleaned to reduce the factors that cause defects such as welding porosity. The arc-starting plate and the base material are of the same material, the welding bevel form is the same, and the length should meet the standard requirements; the manual arc should meet the following requirements: use a welding machine in good condition and with complete functions, and the selected welding rods should be dried in a drying oven; (6) Apply anti-rust paint: use special anti-rust equipment for rust removal, and shot blasting can improve the fatigue strength and corrosion resistance of angle steel. After the angle steel rust removal is inspected and qualified, apply two coats of primer and one coat of topcoat. The paint should be applied evenly and without dripping during the application process.

[0032] The on-site hoisting process for the main frame assembly components of the steel structure balcony: Before hoisting the prefabricated components, the positioning axis, foundation axis and elevation, anchor bolts, diameter and extension length of the prefabricated components must be checked, and the external dimensions, bolt hole positions and diameters of the prefabricated components must be verified. After confirming that they meet the dimensions of the external balcony, the installation center lines at the top and bottom of the prefabricated components and the elevation line at the bottom of the column are marked.

[0033] Based on the actual site conditions, select a boom lift and nearby personnel for hoisting. After the preparatory work is completed, conduct a trial lift. Stop the lift when one end is 100-200mm high to check the rigging and the stability of the crane. After confirming safety, slowly lift the prefabricated assembly and turn it into position. When it is on the installation foundation, you can direct the crane to slowly lower it. When the bottom of the prefabricated assembly is 40-100mm away from the foundation, adjust the two baselines of the prefabricated assembly and the foundation to achieve the accurate position. Direct the crane to lower it into position and tighten all bolts and nuts to reinforce the prefabricated assembly.

[0034] The reinforcement structure for balconies in older residential communities, incorporating seismic damping, strengthens balconies by installing a steel main frame, thereby increasing their load-bearing capacity. Simultaneously, the installed seismic damping structure buffers and absorbs external forces such as earthquakes, reducing damage to the balcony. The steel structure in this solution is lightweight yet robust, providing sufficient reinforcement without excessively increasing the balcony's weight. The four-corner damping design is easy to install, allowing for rapid construction and minimizing disruption to residents' daily lives.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
