Description

Technical Field

[0001] This utility model relates to the field of building structure design technology, and in particular to a reinforcement structure for cantilevered balconies in existing buildings. Background Technology

[0002] Cantilevered balconies are extensions of a building's interior, serving as spaces for residents to breathe fresh air, dry clothes, and display potted plants. They are widely found in existing buildings in older residential communities. However, in some older communities, the earlier construction dates and relatively lower design and construction standards mean that the design and construction of cantilevered balconies often fail to meet long-term usage requirements. Over time, some cantilevered balconies experience cracks, deformation, or even collapse at the joints of the cantilevered floor slabs. This not only affects the daily use of the balcony but also poses significant safety hazards. Therefore, reinforcement of the balcony slabs is necessary to ensure the stability of the cantilevered balcony.

[0003] Currently, the main methods for reinforcing cantilevered balconies include the superposition method, the addition of supports, and the recasting method. However, the superposition method requires the balcony slab to retain a certain strength and places high demands on its load-bearing capacity, thus limiting its applicability. The recasting method requires removing the original balcony slab and recasting it. Due to the limitations of the era, the original balcony slab often has low-quality concrete and insufficient reinforcement, making recasting impossible once removed. The addition of supports typically involves providing additional support to the balcony slab, but existing support structures often have poor support effectiveness and fail to consider the installation of clothes racks, ceiling lights, etc., which can easily cause secondary damage to the balcony slab. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcement structure for cantilevered balconies in existing buildings, so as to solve the problems of poor support effect and easy secondary damage to the balcony slab in the existing reinforcement methods for cantilevered balconies.

[0005] To achieve the above objectives, this utility model provides a reinforcement structure for an existing cantilevered balcony, including at least two parallel main reinforcing steel beams, at least one edge-sealing reinforcing beam, and at least one diagonal brace set at the bottom of the cantilevered balcony. The edge-sealing reinforcing beam is set parallel to the wall at the cantilevered end of the cantilevered balcony. One end of the main reinforcing steel beam is perpendicularly connected to the wall, and the other end extends toward the cantilevered end of the cantilevered balcony and is perpendicularly connected to the edge-sealing reinforcing beam. One end of the diagonal brace is connected to the wall, and the other end is connected to the bottom surface of the main reinforcing steel beam. The diagonal brace, the wall, and the main reinforcing steel beam form a triangular support.

[0006] Optionally, the existing building cantilever balcony reinforcement structure further includes a first connecting plate, a second connecting plate, a plurality of tie rods and a plurality of first nuts. The first connecting plate and the second connecting plate are respectively attached to the inner and outer sides of the wall, and the second connecting plate is fixed to one end of the main reinforcement steel beam. The tie rods penetrate vertically through the wall and both ends penetrate the first connecting plate and the second connecting plate respectively, and are then locked by the first nuts.

[0007] Optionally, the existing building cantilever balcony reinforcement structure also includes a third connecting plate, several chemical anchors and several second nuts. The third connecting plate is fixed to one end of the diagonal brace and fits against the outer surface of the wall. One end of the chemical anchor is inserted into the wall, and the other end passes through the third connecting plate and is locked by the second nut.

[0008] Optionally, the other end of the diagonal brace is welded or bolted to the bottom surface of the main reinforcing steel beam.

[0009] Optionally, the distance from the other end of the diagonal brace to the wall shall not be less than half the length of the main reinforcing steel beam.

[0010] Optionally, the main reinforcing steel beams are two beams located on opposite sides of the cantilevered balcony.

[0011] Optionally, the existing building cantilever balcony reinforcement structure also includes several installation steel beams, which are arranged parallel to the wall between two main reinforcement steel beams, and the two ends of the installation steel beams are respectively perpendicularly connected to the two main reinforcement steel beams.

[0012] Optionally, the installation steel beams are multiple beams and are evenly distributed along the cantilever direction of the cantilevered balcony.

[0013] Optionally, the cross-sectional dimensions of the mounting steel beam are smaller than the cross-sectional dimensions of the edge-sealing reinforcement beam.

[0014] Optionally, several mounting holes are pre-drilled on the two main reinforcing steel beams.

[0015] The existing building cantilever balcony reinforcement structure provided by this utility model has at least one of the following beneficial effects:

[0016] 1) By setting the main reinforcing steel beam and the edge-sealing reinforcing beam at the bottom of the cantilevered balcony, and setting the diagonal brace to form a triangular support for the cantilevered balcony, the cantilevered balcony can be effectively supported and reinforced, ensuring the stability of the cantilevered balcony. At the same time, the main reinforcing steel beam can also be used for the later installation of clothes racks, ceiling lights and other suspended structures, avoiding secondary damage to the cantilevered balcony during later installation.

[0017] 2) By setting the diagonal brace, the main reinforcing steel beam can be supported, avoiding excessive load on the end of the main reinforcing steel beam away from the wall. The load of the cantilever balcony and the main reinforcing steel beam can be transferred to the wall through the diagonal brace, resulting in better reinforcement and better stability of the cantilever balcony.

[0018] 3) By setting the installation steel beam between the two main reinforcing steel beams, the cantilevered balcony can be further reinforced, improving the reinforcement effect. Furthermore, the installation steel beam can also serve as the installation frame for subsequent clothes racks, ceiling lights, or other suspended structures, preventing secondary damage to the cantilevered balcony during later installations.

[0027] Please refer to Figures 1-2 This embodiment provides a reinforcement structure for an existing cantilevered balcony, including at least two parallel main reinforcing steel beams 2, at least one edge-sealing reinforcing beam 3, and at least one diagonal brace 4, which are set at the bottom of the cantilevered balcony 1. The edge-sealing reinforcing beam 3 is set parallel to the wall 5 at the cantilever end of the cantilevered balcony 1. One end of the main reinforcing steel beam 2 is perpendicularly connected to the wall 5, and the other end extends toward the cantilever end of the cantilevered balcony 1 and is perpendicularly connected to the edge-sealing reinforcing beam 3. One end of the diagonal brace 4 is connected to the wall 5, and the other end is connected to the bottom surface of the main reinforcing steel beam 2. The diagonal brace 4, the wall 5, and the main reinforcing steel beam 2 form a triangular support.

[0028] The cantilever balcony reinforcement structure provided in this embodiment is mainly applicable to cantilever balconies 1 in existing buildings, especially cantilever balconies 1 in old residential areas. By setting the main reinforcing steel beam 2 and the edge-sealing reinforcing beam 3 at the bottom of the cantilever balcony 1, and simultaneously setting the diagonal brace 4 to form a triangular support for the cantilever balcony 1, the cantilever balcony 1 can be effectively supported and reinforced, ensuring the stability of the cantilever balcony 1 in use. At the same time, the main reinforcing steel beam 2 can also serve as a supporting frame for the later installation of clothes racks, ceiling lights, and other suspended structures, avoiding secondary damage to the cantilever balcony 1 during later installation.

[0029] In this embodiment, the existing building cantilever balcony reinforcement structure also includes a first connecting plate 6, a second connecting plate 7, a plurality of tie rods 8 and a plurality of first nuts. The first connecting plate 6 and the second connecting plate 7 are respectively attached to the inner and outer sides of the wall 5, and the second connecting plate 7 is fixed to one end of the main reinforcement steel beam 2. The tie rods 8 penetrate vertically through the wall 5 and both ends penetrate through the first connecting plate 6 and the second connecting plate 7 respectively, and are then locked by the first nuts.

[0030] Specifically, the main reinforcing steel beam 2 can be made of steel components such as I-beams and H-beams. The first connecting plate 6 and the second connecting plate 7 can both be made of steel plates. The second connecting plate 7 can be pre-welded and fixed to one end of the main reinforcing steel beam 2. The two ends of the tie rod 8 pass through the first connecting plate 6 and the second connecting plate 7 respectively and are locked by the first nut, thereby realizing the installation and fixation of the main reinforcing steel beam 2 at the bottom of the cantilevered balcony 1.

[0031] In this embodiment, the existing building cantilever balcony reinforcement structure also includes a third connecting plate 9, a number of chemical anchors 10 and a number of second nuts. The third connecting plate 9 is fixed to one end of the diagonal brace 4 and fits against the outer surface of the wall 5. One end of the chemical anchor 10 is inserted into the wall 5, and the other end passes through the third connecting plate 9 and is locked by the second nut.

[0032] Specifically, the diagonal brace 4 can be made of steel components such as I-beams or H-beams, and the third connecting plate 9 can be made of steel plate. The third connecting plate 9 can be pre-welded and fixed to one end of the diagonal brace 4 and fixed by chemical anchors 10 implanted in the wall 5, thereby realizing the installation and fixation of one end of the diagonal brace 4 at the bottom of the cantilevered balcony 1.

[0033] Furthermore, the other end of the diagonal brace 4 is welded or bolted to the bottom surface of the main reinforcing steel beam 2. By setting the diagonal brace 4, the main reinforcing steel beam 2 can be supported, preventing the end of the main reinforcing steel beam 2 away from the wall 5 from bearing excessive load. The load of the cantilevered balcony 1 and the main reinforcing steel beam 2 can be transferred to the wall 5 through the diagonal brace 4, resulting in better reinforcement and making the cantilevered balcony 1 more stable.

[0034] Preferably, the distance from the other end of the diagonal brace 4 to the wall 5 is not less than half the length of the main reinforcing steel beam 2. That is, the distance from the connection point of the diagonal brace 4 and the main reinforcing steel beam 2 to the wall 5 should be greater than or equal to the distance from the connection point to the cantilever end of the cantilevered balcony 1, so as to improve the supporting effect of the diagonal brace 4.

[0035] In this embodiment, the number of diagonal braces 4 can be designed according to the number of main reinforcing steel beams 2. Preferably, the number of diagonal braces 4 is equal to the number of main reinforcing steel beams 2, that is, each main reinforcing steel beam 2 is provided with a diagonal brace 4 to ensure a good support effect.

[0036] In this embodiment, considering the construction cost while ensuring the reinforcement meets the requirements, there are two main reinforcing steel beams 2 located on opposite sides of the cantilevered balcony 1. Of course, the number of main reinforcing steel beams 2 can be further increased according to construction needs; this invention does not impose any limitations on this.

[0037] Furthermore, the existing building cantilever balcony reinforcement structure also includes several installation steel beams 11. These installation steel beams 11 are arranged parallel to the wall 5 between two main reinforcing steel beams 2, and their ends are perpendicularly connected to the two main reinforcing steel beams 2 respectively. In this embodiment, the installation steel beams 11 can be made of steel components such as I-beams or H-beams. The installation steel beams 11 are arranged parallel to the edge-sealing reinforcement beams 3 to further reinforce the cantilever balcony 1 and improve the reinforcement effect. In addition, the installation steel beams 11 can also serve as the installation frame for subsequent clothes racks, ceiling lights, or other suspended structures, preventing secondary damage to the cantilever balcony 1 during later installations.

[0038] In this embodiment, the installation steel beam 11 and the main reinforcing steel beam 2 can be connected by welding or bolts.

[0039] Preferably, the installation steel beams 11 are multiple and are evenly distributed along the cantilever direction of the cantilever balcony 1. This utility model does not limit the number of installation steel beams 11.

[0040] In this embodiment, the cross-sectional dimension of the mounting steel beam 11 is smaller than the cross-sectional dimension of the edge-sealing reinforcement beam 3. For example, both the mounting steel beam 11 and the edge-sealing reinforcement beam 3 are made of I-beams, and the cross-sectional dimension of the I-beams used in the mounting steel beam 11 is smaller than the cross-sectional dimension of the I-beams used in the edge-sealing reinforcement beam 3.

[0041] In this embodiment, there is one edge-sealing reinforcement beam 3. Of course, depending on the construction requirements, multiple edge-sealing reinforcement beams 3 can also be set. For example, there are three main reinforcement steel beams 2, and two edge-sealing reinforcement beams 3, with one edge-sealing reinforcement beam 3 set at the end of each pair of adjacent main reinforcement steel beams 2.

[0042] Alternatively, several mounting holes are pre-drilled on the two main reinforcing steel beams 2. It is understandable that, considering the subsequent installation of clothes racks, ceiling lights, etc., in addition to adding the mounting steel beams 11, mounting holes can also be pre-drilled on the main reinforcing steel beams 2. This design can also avoid secondary damage to the cantilevered balcony 1 during later installation.

[0043] In summary, this utility model embodiment provides a reinforcement structure for an existing cantilevered balcony. By setting the main reinforcing steel beam 2 and the edge-sealing reinforcing beam 3 at the bottom of the cantilevered balcony 1, and simultaneously setting the diagonal brace 4 to form a triangular support for the cantilevered balcony 1, the cantilevered balcony 1 can be effectively supported and reinforced, ensuring the stability of the cantilevered balcony 1 in use. At the same time, the main reinforcing steel beam 2 can also serve as a support frame for the later installation of clothes racks, ceiling lights and other suspended structures, avoiding secondary damage to the cantilevered balcony 1 during later installation.

[0044] Furthermore, it should be understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. For any person skilled in the art, many possible variations and modifications can be made to the present invention's technical solutions using the disclosed technical content, or equivalent embodiments can be modified accordingly, without departing from the scope of the present invention's technical solutions. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention's technical solutions, shall still fall within the protection scope of the present invention's technical solutions.
