Description

Technical Field

[0001] This utility model relates to the field of building structure technology, and in particular to a concrete structure with a cantilevered balcony added without diagonal bracing. Background Technology

[0002] A cantilevered balcony extends outward through a floor slab or cantilever beam to form a cantilever structure. The outermost end has no load-bearing wall or column and relies solely on the cantilevered components (such as floor slabs or cantilever beams) connected to the main structure for load-bearing.

[0003] As described in announcement number CN214364026U, a light-transmitting cantilevered balcony with unrestricted depth and good indoor lighting is described. This utility model's light-transmitting cantilevered balcony includes an outwardly cantilevered balcony floor (1), with at least one vertical through-hole (2) on the balcony floor (1). The through-hole (2) is sealed by a light-transmitting block (21) that allows light to pass through but not through the interior. Preferably, the light-transmitting block (21) is made of tempered glass.

[0004] The patented cantilevered balcony design allows the lower-level rooms to remain unaffected by natural light. However, existing cantilevered balcony support panels are usually one-piece designs, and since the balcony support panel needs to cover the entire cantilevered area, the overall design results in a long single panel, making transportation and hoisting inconvenient. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing cantilever balcony support panels are usually one-piece, and the balcony support panel needs to cover the entire cantilever area. The one-piece design results in a long length of a single panel, which is inconvenient for transportation and hoisting.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cantilevered balcony without diagonal bracing in a concrete structure, comprising a main support, wherein a splicing reinforcement structure is provided on the inner side of the main support, the splicing reinforcement structure comprising an inner support, wherein reinforcing ribs are welded inside the inner support, and a first support plate and a second support plate are respectively connected to the two side surfaces of the inner support, wherein a locking block is provided on the side of the first support plate near the second support plate, and a locking groove is provided on the second support plate at the position matching the locking block, wherein a first bolt is connected to the surface of both the first support plate and the second support plate, wherein a steel reinforcement layer is laid on the top of the first support plate and the second support plate, and a cement layer is poured on the surface of the steel reinforcement layer, wherein a handrail body is provided at the upper end of the cement layer.

[0007] Furthermore, the first support plate is engaged with the second support plate via a locking block, and the first bolt passes through the first and second support plates to form a threaded connection with the inner bracket.

[0008] Furthermore, the size of the inner support is matched with the size of the first support plate and the second support plate.

[0009] Furthermore, the top of the main support is provided with a disassembly assembly, which includes a socket into which a handrail bracket is inserted, and side lugs are connected to the top of both sides of the handrail bracket.

[0010] Furthermore, a second bolt is inserted into the inside of the side ear, and a threaded hole is provided at the position where the armrest body matches the second bolt.

[0011] Furthermore, the second bolt, after passing through the side lug, forms a threaded connection with the threaded hole.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when installing, the first support plate is spliced ​​with the second support plate by a clip, and then fixed by the first bolt. After that, the main bracket and the inner bracket are welded together. At the same time, the distributed steel reinforcement layers form a reinforced area with an enlarged cross section, which improves the stability of the cantilever balcony and avoids the problem that the support plate is usually a single piece, which is inconvenient to transport and move.

[0013] 2. In this utility model, the handrail bracket is made of stainless steel tube. When the handrail bracket is dented due to a collision and needs to be replaced, the second bolt can be removed directly, and the handrail bracket can be slightly bent outward and then pulled upward to disassemble it. After that, the new handrail bracket can be installed and fixed, which improves the overall practicality and avoids the problem of inconvenience when a set of handrail brackets needs to be replaced by traditional welding.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides a cantilevered balcony added to a concrete structure without diagonal bracing, including a main support 1. A splicing reinforcement structure 2 is provided on the inner side of the main support 1. The splicing reinforcement structure 2 includes an inner support 201, with reinforcing ribs 202 welded inside the inner support 201. A first support plate 203 and a second support plate 205 are respectively connected to the two side surfaces of the inner support 201. A locking block 204 is provided on the side of the first support plate 203 near the second support plate 205. A locking groove is provided on the second support plate 205 at the position where it matches the locking block 204. The first support plate 203 and the second support plate 205... The surface of 5 is connected with the first bolt 206. The top of the first support plate 203 and the second support plate 205 is covered with a steel reinforcement layer 207. The surface of the steel reinforcement layer 207 is covered with a cement layer 208. The upper end of the cement layer 208 is provided with the handrail body 209. The first support plate 203 is connected to the second support plate 205 by a locking block 204. The first bolt 206 passes through the first support plate 203 and the second support plate 205 and is threadedly connected to the inner bracket 201. The size of the inner bracket 201 matches the size of the first support plate 203 and the second support plate 205.

[0019] The effect achieved in Embodiment 1 is that, during installation, the components of the main bracket 1 and the inner bracket 201 can be assembled by welding first. Then, the locking block 204 of the first support plate 203 is inserted into the slot of the second support plate 205 and placed on the surface of the inner bracket 201. It is then fixed by multiple sets of first bolts 206, so that the first bolts 206 pass through the first support plate 203 and the second support plate 205 and are threadedly connected to the inner bracket 201. At this time, a steel reinforcement layer 207 can be laid on the surface of the first support plate 203 and the second support plate 205. Finally, a cement layer 208 is poured.

[0020] Example 2, as Figure 1 and Figure 4 As shown, the top of the main support 1 is provided with a disassembly and assembly component 3. The disassembly and assembly component 3 includes a socket 301. A handrail support 302 is inserted into the socket 301. Side ears 303 are connected to the top of both sides of the handrail support 302. A second bolt 304 is inserted into the side ears 303. A threaded hole 305 is opened at the position where the handrail body 209 matches the second bolt 304. The second bolt 304 passes through the side ears 303 and forms a threaded connection with the threaded hole 305.

[0021] The effect achieved in Embodiment 2 is as follows: The operator first uses an electric wrench with the appropriate torque to disassemble the four sets of second bolts 304 in a diagonal sequence to avoid deformation of the side ears 303 due to unilateral force. Then, the operator gently pushes the armrest bracket 302 downwards to the bottom of the insertion hole 301, utilizing the 5cm gap between the top and the armrest body 209 as operating space. Holding the upper part of the bracket with both hands, the operator applies a 5°-8° tilt angle outwards, not exceeding 40% of the elastic limit of the 304 stainless steel, and slowly pulls upwards to disengage the bottom of the bracket from the insertion hole 301. During this process, it is necessary to check whether there are any bolt fragments or foreign objects remaining on the inner wall of the insertion hole 301, and clean it with compressed air to ensure there are no obstructions. Afterwards, pulling upwards again allows for disassembly. The bottom of the new handrail bracket 302 is inserted into the surface of the socket 301 and bent so that the bottom of the handrail bracket 302 can be smoothly inserted into the socket 301. Then, the handrail bracket 302 is pushed upward so that the top of the handrail bracket 302 can contact the handrail body 209. Finally, it is installed and fixed by passing the second bolt 304 through the side ear 303 and then into the threaded hole 305. This improves the overall practicality and avoids the inconvenience of traditional welding fixation when a set of handrail brackets 302 needs to be replaced. At the same time, in order to reduce dust entering the socket 301, a stainless steel decorative cover can be placed on the surface of the handrail bracket 302 during installation.

[0022] Working principle: During installation, the first support plate 203 is spliced ​​with the second support plate 205 via the clamp 204, and then fixed with the first bolt 206. After that, the main bracket 1 and the inner bracket 201 are welded together. At the same time, the distributed steel reinforcement layer 207 forms a reinforced area with an enlarged cross-section, improving the stability of the cantilever balcony. This avoids the problem that the support plate is usually a single piece, which is inconvenient to transport and move. The handrail bracket 302 is made of stainless steel pipe. When the handrail bracket 302 is dented due to impact and needs to be replaced, the second bolt 304 is removed directly, and the handrail bracket 302 is slightly bent outward and pulled upward to remove it. Then, the new handrail bracket 302 can be installed and fixed. This improves the overall practicality and avoids the inconvenience of the traditional welding method when a set of handrail brackets 302 needs to be replaced.

[0023] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
