The seat component 2 is installed on the channel steel 3. The seat component 2 is in a non-parallel state with the horizontal plane. A slope of 1% is reserved between the channel steel 3 and the horizontal plane during installation. Therefore, there is a slope of 1% on the surface of the seat component 2. The model of the steel bars in the steel bar framework 9 is HRB400, and the diameter of the steel bars is 12 mm.

[0029] The above combined prefabricated bench is composed of a precast concrete component 1 and a seat component 2, with a high turnover rate of use. The precast concrete component 1 has a large self-weight, ensuring the stability and safety of the bench, not being prone to tipping over, and being able to carry multiple people at the same time. The combined prefabricated structure can change the material of the seat component 2 according to the scene needs and be reused multiple times. The precast concrete component 1 can be sprayed with outdoor paints of various colors according to the use scene or be painted and decorated in other ways. The steel bar skeleton 9 enables the precast concrete component 1 to have better strength. The first round steel 7 is equivalent to a hanger bar, preventing the precast concrete component 1 from having local severe damage and preventing the precast concrete component 1 from generating excessive cracks, which may cause structural damage, thus increasing the stability of the bench structure. The steel plate 5 is embedded in the precast concrete component 1, and the steel plate 5, channel steel 3, and second round steel 8 form a triangular connection structure for supporting the seat component 2, improving the reliability of the bench structure. The non-parallel state between the seat component 2 and the horizontal plane ensures that there will be no water accumulation on the surface of the bench after rain, thereby preventing the normal use of the bench from being affected by rain. Moreover, both the precast concrete component 1 and the seat component 2 can be used by users for rest, increasing the practicality of the bench. The bench structure provided by this application can be promoted and used in fields such as municipal engineering, construction engineering, garden engineering, etc., as well as temporary residences such as construction sites.

[0030] As Figure 1 shown, in this embodiment, multiple reserved notches 10 are provided on the precast concrete component 1; the reserved notches 10 can effectively avoid stress concentration, strengthen the support and stability of the precast concrete component 1, reduce the stress and cracks inside the concrete, prevent air bubbles from appearing inside the concrete, and improve the durability of the concrete structure. The depth of the reserved notch 10 is 250 mm, the width of the reserved notch 10 is 100 mm, the height of the reserved notch 10 is 500 mm, and the interval distance between each reserved notch 10 is 600 mm. The size data of each reserved notch 10 and the interval distance between multiple reserved notches 10 can be adjusted according to actual use requirements.

[0031] As Figure 3 shown, in this embodiment, the top surface of the precast concrete component 1 is in a non-parallel state with the horizontal plane; it can ensure that the surface of the precast concrete component 1 will not accumulate water after rain, preventing corrosion damage to the precast concrete component 1. A 1% slope is reserved on the top surface of the precast concrete component 1, which is conducive to drainage.

[0032] As Figure 1As shown, in this embodiment, the connection between the channel steel 3 and the steel plate 5 is welding; welding can effectively improve the connection stability between the channel steel 3 and the steel plate 5, and further make the structure of the seat assembly 2 more stable when bearing people, and will not cause damage to people due to unstable connection. In addition, welding can adapt to the connection of various materials. Whether it is the same material or different materials, as long as a certain welding area can be formed after heating, welding can be carried out. Therefore, it also ensures a reliable connection between the channel steel 3 and the steel plate 5. Between the channel steel 3 and the second round steel 8, and between the second round steel 8 and the steel plate 5, welding is also used for connection. The channel steel 3 is 10# channel steel, which has good rigidity and meets the use requirements.

[0033] As Figure 1 shown, in this embodiment, a second bolt 6 is provided at the connection between the steel plate 5 and the precast concrete component 1; the diameter of the second bolt 6 is 20 mm. The steel plate 5 is pre-embedded in the precast concrete component 1. However, due to considerations of connection stability and improving the reliability of the bench structure, a second bolt 6 is also provided at the connection between the steel plate 5 and the precast concrete component 1. The second bolt 6 is connected to both the steel plate 5 and the precast concrete component 1 at the same time, providing double guarantee for the reliability of the bench structure.

[0034] As Figure 3 shown, in this embodiment, the channel steel 3 is connected to the seat assembly 2 through the first bolt 4; bolt connection can not only improve the reliable stability of the connection between the channel steel 3 and the seat assembly 2, and further improve the reliability of the bench structure, but also has the characteristics of convenient disassembly. The connection between the channel steel 3 and the seat assembly 2 can be disassembled more conveniently. In addition, it is also convenient to change the material of the seat assembly 2 according to the scene needs for multiple repeated uses, improving the practicability and scene adaptability of the bench. The seat assembly 2 can be composed of outdoor anti-corrosion wood or stainless steel bearing plates. The seat assembly 2 is formed by splicing multiple pieces of outdoor anti-corrosion wood or stainless steel bearing plates. The gap between multiple pieces of outdoor anti-corrosion wood or stainless steel bearing plates is 5 mm, aiming to prevent water from accumulating on the surface; the first bolt 4 is an internal hexagonal high-strength bolt, and the diameter of the first bolt 4 is 12 mm. The internal hexagonal high-strength bolt has high rigidity and meets the use requirements.

[0035] As Figure 3As shown, in this embodiment, the surfaces of the steel plate 5, the first round steel 7, and the second round steel 8 are all galvanized. The zinc layer can effectively isolate the steel plate 5, the first round steel 7, and the second round steel 8 from contact with the outside world, prevent corrosion by substances such as oxygen, moisture, acids, and alkalis, improve the weather resistance and corrosion resistance of the steel plate 5, the first round steel 7, and the second round steel 8. The galvanizing treatment can extend the service life of the steel plate 5, the first round steel 7, and the second round steel 8, reduce the costs of maintenance and replacement, and can also effectively resist wear and scratches, increasing the wear resistance of the steel plate 5, the first round steel 7, and the second round steel 8. In addition, the zinc layer is bright and has a good appearance effect, which can enhance the beauty and decorativeness of the bench.

[0036] As Figure 1 shown, in this embodiment, the length of the steel plate 5 is 300 mm, the width of the steel plate 5 is 300 mm, and the thickness of the steel plate 5 is 20 mm. The steel plate 5 is used to connect with the second round steel 8 and the channel steel 3 to form a triangular structural frame, and then support the installation of the seat assembly 2. The dimensional data of the steel plate 5 can be adjusted according to actual usage requirements.

[0037] As Figure 3 shown, in this embodiment, the cross-sectional diameters of the first round steel 7 and the second round steel 8 are both 18 mm. The models of the first round steel 7 and the second round steel 8 are both HPB300. The cross-sectional diameter dimensions of the first round steel 7 and the second round steel 8 can be adjusted according to actual usage requirements. The first round steel 7 is equivalent to a hanger bar, which prevents the precast concrete component 1 from suffering local severe damage, prevents the precast concrete component 1 from generating excessive cracks, and causes structural damage, increasing the stability of the bench structure.

[0038] As Figure 1 shown, in this embodiment, the length of the precast concrete component 1 is 2400 mm, the width of the precast concrete component 1 is 500 mm, and the height of the precast concrete component 1 is 500 mm. The precast concrete component 1 serves as the support for the seat assembly 2 and is used to install the structure of the seat assembly 2. The precast concrete component 1 uses C40F300 concrete with normal and reasonable steel reinforcement. The weight of the precast concrete component 1 is about 1500 kg. The precast concrete component 1 has a large self-weight, ensuring the stability and safety of the bench, not being prone to tipping over, and being able to carry multiple people at the same time. The dimensional data of the precast concrete component 1 can be adjusted according to actual usage requirements.

[0039] As Figures 1 to 3As shown, in this embodiment, first, a steel bar skeleton 9 is assembled using steel bars, and at the same time, embedded steel plates 5 are installed. The first round steel 7 is welded and fixed on the steel bar skeleton 9. Then, the formwork for pouring concrete is assembled. The formwork uses wood-plastic formwork, and the bottom formwork uses a steel plate with a thickness of 20 mm. Then, concrete is poured to make the precast concrete component 1. It should be noted that when pouring concrete, the vibration should be dense. At the same time, a 1% slope is reserved on the top surface of the precast concrete component 1. The embedded steel plate 5 is connected to the second bolt 6, and the channel steel 3, the embedded steel plate 5, and the second round steel 8 are welded and assembled. Bolt connection holes are reserved on the channel steel 3, and a 1% slope is reserved between the channel steel 3 and the horizontal plane. Subsequently, multiple outdoor anti-corrosion woods or stainless steel bearing plates are connected to the channel steel 3 through the first bolt 4. In addition, grooves are customized on the anti-corrosion wood or stainless steel bearing plate to ensure that the surface after the installation of the first bolt 4 is 3 mm lower than the surface of the anti-corrosion wood or stainless steel bearing plate to prevent scratching the user.

[0040] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description.
