Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a rest platform structure for a prefabricated staircase. Background Technology

[0002] The landing platform of a precast staircase is an important component of precast staircases. It refers to the horizontal platform connecting two stair flights within a stairwell. It is usually a rectangular or square flat plate structure, and its function is to provide a place for people to rest and change direction when going up or down the stairs. It can also serve as a buffer zone in the stairwell, increasing the safety and comfort of the staircase.

[0003] Staircase landing platforms are mostly constructed using on-site casting. This method involves a complex construction process, requiring on-site formwork erection, rebar tying, concrete pouring, and prolonged curing. On-site casting not only consumes significant manpower, resources, and time, but is also heavily influenced by external factors such as weather, making it difficult to guarantee the stability of the construction progress. Furthermore, traditional welding and other connection methods require extremely high levels of worker skill when connecting the landing platform to the main building structure, making it difficult to guarantee welding quality. Welding defects can seriously affect the overall safety of the platform. Moreover, the high temperatures generated during welding may damage the performance of building structural materials, weakening the structure's durability.

[0004] Meanwhile, different building projects have different spatial size requirements. In the past, custom-made rest platform structures were designed for specific buildings, resulting in high production costs. Each project required redesign and mold making, which consumed a lot of design resources and material costs. Furthermore, due to the lack of versatility, prefabricated components were difficult to mass-produce and could not reduce costs through economies of scale. Utility Model Content

[0016] (III) Beneficial Effects

[0017] In summary, this utility model has at least one of the following beneficial technical effects:

[0018] 1. The rest platform structure of this prefabricated staircase has a clear and simple overall installation process. First, move the device to the designated position, and then use bolts to connect the first box to the mounting plate. Compared with complex welding or other connection methods, bolt connection is fast and easy to adjust, which greatly shortens the installation time, improves construction efficiency, and reduces manpower input.

[0019] 2. The resting platform structure of this prefabricated staircase allows for flexible adjustment of the platform length by pulling out the sleeve through the second box, and by coordinating the movement of the second and third reinforcing bars within the collar, to adapt to the size requirements of different building spaces. This eliminates the need to customize a special platform structure for a specific building, improving the product's versatility and reducing production costs.

[0020] 3. The rest platform structure of this precast staircase involves fixing the first and second boxes to the wall, and then injecting concrete into the boxes and sleeves. After the concrete solidifies, it forms a tight whole with the boxes and the wall, which enhances the connection strength between the platform and the wall, improves the seismic performance of the platform, and enables it to remain stable in various environments.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-3 A prefabricated staircase landing structure includes a main body 1, and further includes:

[0028] The telescopic platform includes a first housing 2 and a second housing 3. A mounting plate 4 is threaded to the bottom of the first housing 2 and connected to the main body 1. A sleeve 5 is fixedly connected inside the second housing 3, and the sleeve 5 is slidably connected to the first housing 2. The telescopic platform, composed of the first housing 2 and the second housing 3, is slidably connected via the sleeve 5. This design allows for flexible adjustment of the platform length according to the actual installation scenario, adapting to different stairwell space requirements and improving the versatility and ease of installation of the rest platform. Multiple first reinforcing bars 6 are longitudinally connected inside the first housing 2, the second housing 3, and the cylinder. Multiple first reinforcing bars 6 are longitudinally connected within the box body 2, the second box body 3, and the cylinder, greatly enhancing the longitudinal load-bearing capacity of the structure and effectively improving the overall strength and stability of the platform. This ensures that it can withstand significant pressure without deformation or damage during long-term use. Multiple second reinforcing bars 7 and multiple third reinforcing bars 8 are horizontally fixedly connected within the first box body 2 and the second box body 3, respectively. Both the second and third reinforcing bars 7 and 8 are equipped with collars 9, and are connected through these collars. This connection method enhances the lateral stability of the platform, allowing for better distribution of loads in the horizontal direction. To withstand loads and prevent lateral displacement or torsion of the housing under stress, the top of the sleeve 5 has an injection port 10 for injecting filling concrete into the sleeve 5 during installation. The concrete further enhances the tightness and integrity of the connection between the sleeve 5 and the first housing 2 and the second housing 3, improving the structure's seismic performance and load-bearing capacity. A connecting shell 11 is fitted onto the sleeve 5, which elevates the sleeve 5 to make the first housing 2, the second housing 3, and the housing flush. This flush alignment facilitates subsequent surface treatment during installation, reducing the workload for construction personnel. Additional treatment is needed for uneven parts, which reduces construction difficulty and improves construction efficiency. Anti-slip textures are provided on the first box 2, the second box 3, and the connecting shell 11, which significantly increases the friction of the platform surface and can effectively prevent people from slipping when walking on the rest platform, thus improving safety during use. Multiple reinforcing rods 12 are fixedly connected between the first box 2 and the mounting plate 4. The reinforcing rods 12 further enhance the connection strength between the first box 2 and the mounting plate 4, making the connection between the entire platform and the main body 1 more firm and reliable, and reducing the risk of loosening due to long-term use or uneven stress.

[0029] In summary, the working principle and process of the rest platform structure of this prefabricated staircase are as follows: When in use, firstly, the device is moved to the required position, then the first box 2 is connected to the mounting plate 4 with bolts, and the reinforcing rod 12 is welded to the first box 2 and the mounting plate 4. Then, the second box 3 is pulled, so that the sleeve 5 slides out of the first box 2. During the movement, the second reinforcing bar 7 and the third reinforcing bar 8 move in the collar 9. After being stretched to the required length, the first box 2 and the second box 3 are fixed to the wall. Then, concrete is injected into the first box 2, the second box 3 and the sleeve 5 through the injection port 10. Finally, the connecting shell 11 is cut to the required size and installed on the sleeve 5.

[0030] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
