[0024] like Figures 1-3 As shown, this utility model provides a steel structure step for a tiered conference room, which mainly includes a support leg 1, a mounting steel plate 2, a step base layer 3, and a connecting base layer 5.

[0025] The support legs 1 are in multiple sets, each set consisting of multiple legs of the same height. These sets of support legs 1 are arranged sequentially from front to back, gradually increasing in height along the arrangement direction. The support legs 1 provide vertical support to the overall structure. Through the arrangement of multiple sets of support legs 1, the entire stepped structure can be stably supported, and the gradually increasing design meets the slope requirements of the stepped conference room. The support legs 1 in this invention are made of H-beams, possessing high structural strength, strong load-bearing capacity, and good stability. A base 6 is fixedly installed at the bottom of each support leg 1, and the base 6 can be locked to the bottom surface with bolts. The distance between two adjacent support legs 1 is less than 3 meters, and a support plate 4, which can be angle steel, is fixedly installed between each pair of adjacent support legs 1. The smaller spacing between the support legs 1 and the installation of the support plates 4 enhance the stability of the support legs 1 and the overall structural strength. Figure 1 As shown, the support plate 4 can be horizontally positioned; in another embodiment, as... Figure 3 As shown, the support plate 4 can also be set at an angle. Specifically, the support plate 4 gradually rises from front to back, which is consistent with the gradually rising arrangement direction of the support legs 1, further ensuring the overall lateral support.

[0026] Multiple mounting steel plates 2 are fixedly installed on top of each set of support legs 1. The mounting steel plates 2 are H-beams placed sideways, which have high structural strength, strong load-bearing capacity, good stability, and facilitate the installation of the step base layer 3. Specifically, the mounting steel plates 2 include a bottom plate 21, a web plate 22, and a top plate 23 connected vertically from bottom to top. The height of the top surface of the bottom plate 21 of each mounting steel plate 2 is equal to the height of the top surface of the top plate 23 of the mounting steel plate 2 in front of it. Multiple step base layers 3 are laid horizontally between two adjacent sets of support legs 1. One end of each step base layer 3 is fixedly connected to the top surface of the top plate 23 of the mounting steel plate 2, and the other end is fixedly connected to the top surface of the bottom plate 21 of another mounting steel plate 2, providing a stable foundation for the installation of the step base layer 3 and ensuring that the step base layer 3 can be connected smoothly.

[0027] The base layer 3 constitutes the main part of the steps, enabling pedestrian access and the placement of tables and chairs. The base layer 3 comprises, from bottom to top, a floor deck 01, a two-way reinforcing layer 02, a concrete pouring layer 03, a cement mortar leveling layer 04, a self-leveling leveling layer 05, and a polyvinyl chloride (PVC) sheet 06. The floor deck 01 provides foundation support, the two-way reinforcing layer 02 enhances structural strength, the concrete pouring layer 03 increases stability, the cement mortar leveling layer 04 and the self-leveling leveling layer 05 ensure a smooth surface, and the PVC sheet 06 provides good wear resistance and slip resistance.

[0028] Specifically, the floor deck 01 in this utility model is an open-type floor deck 01, which is convenient to construct and meets the requirements of rapid construction. It can be laid in a short time, and the embossing on the floor deck 01 can generate a large bonding force with the concrete, resulting in high load-bearing capacity. Figure 1 As shown, the opening of the floor deck 01 extends along the arrangement direction of the multiple support legs 1 in each group; as Figure 3 As shown, in another embodiment, the opening of the floor deck 01 extends along the arrangement direction of the multiple sets of support legs 1.

[0029] The bidirectional reinforcement layer 02 includes a first reinforcement layer and a second reinforcement layer arranged sequentially from bottom to top. Both the first and second reinforcement layers include multiple steel bars evenly arranged in the transverse direction. The diameter of the steel bars is 7mm-9mm, with 8mm being optimal. The distance between two adjacent steel bars is between 98mm-102mm, with 100mm being optimal. The steel bars in the first and second reinforcement layers are arranged perpendicularly to form a bidirectional reinforcement mesh, which can better bear the load and improve the load-bearing capacity and crack resistance of the structure.

[0030] The thickness of the concrete pouring layer 03 is 49mm-51mm, with an optimal thickness of 50mm. The standard value of the concrete cube compressive strength is 35MPa, which meets the high load-bearing requirements. The cement mortar leveling layer 04 is a building material made by mixing cement, sand, and water in a certain proportion. The mixed cement mortar is evenly spread on the concrete pouring layer 03 and then smoothed and polished using tools to form the cement mortar leveling layer 04, controlling the surface unevenness of the concrete pouring layer 03 within a certain range. The thickness of the cement mortar leveling layer 04 is 29mm-31mm, with an optimal thickness of 30mm, ensuring the surface of the concrete pouring layer 03 achieves the designed flatness and levelness. The self-leveling leveling layer 05 is used to level the ground, providing a flat and solid base for the subsequent laying of the polyvinyl chloride sheet 06. The thickness of the self-leveling layer 05 is 2.5mm-3.5mm, with an optimal thickness of 3mm. This thickness effectively fills minor unevenness in the floor without excessively raising the floor level, thus minimizing space usage. PVC sheet 06 possesses good flexibility and impact resistance, as well as a certain degree of abrasion resistance; its surface is not easily scratched or worn. The thickness of PVC sheet 06 is also 2.5mm-3.5mm, with an optimal thickness of 3mm. This thickness provides it with sufficient strength and rigidity, allowing it to maintain its shape while facilitating handling and installation.

[0031] Multiple connecting base layers 5 are vertically arranged, located between two adjacent step base layers 3. One end of each connecting base layer 5 is fixedly connected to the rear end of the step base layer 3, and the other end is fixedly connected to the front end of another step base layer 3. Each connecting base layer 5 comprises, from the inside out, a concrete pouring layer 03, a cement mortar leveling layer 04, a self-leveling leveling layer 05, and a polyvinyl chloride sheet 06. Both ends of the connecting base layer 5 are integrally formed with the concrete pouring layer 03, cement mortar leveling layer 04, self-leveling leveling layer 05, and polyvinyl chloride sheet 06 of the step base layers 3 on both sides. The connecting base layer 5 and the step base layer 3 together cover the top of the support leg 1 and the mounting steel plate 2, further enhancing the stability, integrity, and aesthetics of the connection between the steps.

[0032] In this embodiment, a tail support leg of the same height as the last support leg 1 can be set behind it. A tail mounting steel plate is fixedly installed on the tail support leg. A tail step base layer is laid between the last support leg 1 and the tail support leg. The top surface of the tail mounting steel plate is at the same height as the top surface of the mounting steel plate 2 on its front side, and both ends of the tail step base layer are fixedly connected to the top surface of the mounting steel plate 2 and the top surface of the tail mounting steel plate, respectively. This design facilitates the fixed installation of the tail of the step to the side of the wall, ensuring installation stability. A connecting base layer 5 can also be set on the vertical surface in front of the first mounting steel plate to ensure the integrity of the step.

[0033] The specific construction steps of this utility model are as follows:

[0034] Based on the design slope and size requirements of the tiered conference room, determine the number of support legs 1, the quantity of each support leg 1, and its height. Arrange and install each set of support legs 1 in a gradually increasing order from front to back, ensuring that each set of support legs 1 is at the same height and securely installed. Fix the mounting steel plates 2 to the top of each set of support legs 1, ensuring that the bottom height of each mounting steel plate 2 is equal to the top height of the mounting steel plate 2 in front of it. Fixing can be done by welding or bolting, ensuring a firm and reliable connection. Then install the step base layer 3. During installation, first lay the floor deck 01 horizontally between two adjacent sets of support legs 1, fixing one end of the floor deck 01 to the top surface of the mounting steel plate 2 and the other end to the bottom of another mounting steel plate 2. Lay a two-way reinforcement layer 02 on the floor deck 01, arranging the first and second reinforcement layers according to design requirements, ensuring that the diameter, spacing, and vertical relationship of the two layers of reinforcement meet the specifications. Concrete is poured on the bidirectional reinforcement layer 02 and on the vertical surface between the two floor slabs 01, controlling the thickness of the concrete pouring layer 03 to be 50mm. It is then vibrated to ensure compaction, guaranteeing the strength and stability of the concrete. After the concrete has solidified, a cement mortar leveling layer 04 is applied, with a thickness controlled at 30mm, to achieve a smooth surface. Next, a self-leveling layer 05 is applied, with a thickness of 3mm, to further improve surface smoothness. Finally, a 3mm thick polyvinyl chloride sheet 06 is laid, completing the laying of the stepped base layer 3 and the connecting base layer 5.
