Beam and slab reinforcing bars 7 are tied between the reinforcing bars 6 in two adjacent brick formworks 11. A concrete beam and slab 9 is poured on the pad layer 5. The upper ends of the reinforcing bars 6 and the beam and slab reinforcing bars 7 are embedded in the concrete beam and slab 9. A concrete step 8 is provided on the concrete beam and slab 9.
[0026] like Figure 1 and Figure 2 As shown, in this embodiment, the bottom of the brick mold 11 is provided with a protective pad 4, and the lower end of the reinforcing bar 6 is placed on the protective pad 4. By setting the protective pad, the reinforcing bar and the brick mold can be effectively protected.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, the brick mold 11 is arranged horizontally through the left and right sides of the grandstand panel.
[0029] like Figure 3 As shown, in this embodiment, a gap is reserved between the front and rear sides of the reinforcing bar 6 and the front and rear side walls of the brick mold 11 to avoid damage to the brick mold.
[0030] like Figure 3 and Figure 4 As shown, the thickness of the concrete beam slab 9 in this embodiment is greater than the thickness of the cushion layer 5.
[0031] Optionally, the distance between any two adjacent brick molds 11 is equal.
[0032] like Figures 1-4As shown, the upper inner side of the earthwork 1 in this embodiment is provided with four brick molds 11.
[0033] like Figures 1-4 As shown, in this embodiment, the upper surface of the pad layer 5 is aligned with the upper end face of the brick mold 11 in the inclined direction.
[0034] like Figures 1-4 As shown, in this embodiment, the beam and slab reinforcement 7 extends along the inclined direction of the cushion layer 5.
[0035] The construction method of the first-floor reinforced concrete grandstand slab structure in this embodiment is as follows: (1) Earthwork filling: according to the required earthwork volume on site, pre-fill the earthwork to the construction position. (2) Positioning and layout: according to the construction drawings, use instruments such as RTK to locate the plane and elevation positions, and mark the white lime lines for the beam and slab positions. (3) Excavation of beam and slab positions: excavate the earthwork at the beam and slab positions using excavators, manual labor, etc. (4) Layout of brick formwork positions: perform secondary layout of the excavated basic construction site, accurately confirm the plane position and elevation of the brick formwork, and compact and level the earthwork under the brick formwork. (5) Brick formwork masonry: mason the brick formwork according to the on-site positioning lines, requiring full mortar and smooth masonry. After masonry, support the inside of the brick formwork, and provide wooden formwork support on the north side of the brick formwork at the highest and lowest points. (6) Backfilling of the core soil: backfill, level, and compact the core soil between the brick formworks, paying attention not to over-compact to prevent the brick formwork from tilting inward. (7) Foundation layer pouring. A foundation layer is poured under the concrete of the beams and slabs. During pouring, attention should be paid to ensuring the thickness and flatness of the foundation layer. (8) Reinforcement binding. According to the drawings, the reinforcement bars are bound at the positions of the brick formwork. (9) Reinforcement bar placement. The bound reinforcement cage is placed into the brick formwork, and its protective layer is properly supported. The lower part of the grandstand beam is poured, exposing the upper reinforcement bars of the beam. (10) Concrete pouring. The grandstand beam is poured in one go according to the drawings. It is ensured that the concrete of the beam is vibrated in place and the surface is flat. After completion, curing work is carried out in a timely manner.
[0036] In this embodiment, the first-floor reinforced concrete grandstand slab structure achieves a stable and tight connection between the concrete beams and slabs and the main concrete structure by extending a portion of the reinforcing steel bars from the top of the brick formwork and tying them to the beam and slab reinforcement. This facilitates construction and shortens the construction time for supporting and dismantling the step formwork. This first-floor reinforced concrete grandstand slab structure in this embodiment changes the original support method and construction steps, allowing the upper layer of concrete to be poured in one go, saving costs, improving quality, and reducing safety risks.
