[0025] Specifically, the support structure is set at the bottom of the floor formwork 1. The support structure has a first support member 2 and a second support member 3. The first support member 2 is set in the cavity between the upper flange plate 6 and the lower flange plate 7 of the steel beam. The first support member 2 is connected to the lower flange plate 7. The two ends of the second support member 3 are respectively fixedly connected to the two adjacent first support members 2. The second support member 3 abuts against the floor formwork 1 to support the floor formwork 1.

[0026] In this embodiment, a U-shaped cavity is constructed between the upper flange plate 6 and the lower flange plate 7 of the steel beam. The first support member 2 is disposed in the cavity, and the bottom of the first support member 2 is connected to the upper end face of the lower flange plate 7. The first support member 2 is disposed in two oppositely disposed cavities of adjacent steel beams. The left and right ends of the second support member 3 are respectively fixedly connected to the first support member 2 disposed in the two oppositely disposed cavities. The floor template 1 is disposed above the second support member 3 and is connected to the upper end face of the second support member 3. The lower flange plate 7 of the steel beam supports the first support member 2, the first support member 2 supports the second support member 3, and the second support member 3 supports the floor template 1.

[0027] It should be noted that by setting the first support member 2 in the cavity between the upper flange plate 6 and the lower flange plate 7, and fixing the two ends of the second support member 3 to the first support member 2, the second support member 3 supports the floor formwork 1, thereby avoiding the need to erect a full-span scaffold, reducing labor costs and risks. At the same time, it is not necessary to wait for the concrete of the next floor to reach the design strength before the full-span scaffold of the upper floor can be erected. The cast-in-place slab formwork assembly disclosed in this embodiment can start to erect the cast-in-place slab formwork assembly of the upper floor after the concrete of the next floor is poured, which improves construction efficiency and reduces construction time.

[0028] In some embodiments, the top of the first support member 2 has a gap with the upper flange plate 6, and one end of the second support member 3 is disposed in the gap and overlaps with the top of the first support member 2.

[0029] In this embodiment, as Figure 1 As shown, the top of the first support member 2 inside the cavity has a gap with the upper flange plate 6, and one end of the second support member 3 can extend into the gap and overlap with the top of the first support member 2. The top surface of the first support member 2 abuts against the bottom surface of the second support member 3, and the first support member 2 provides the second support member 3 with a vertically upward support force.

[0034] In this embodiment, as Figure 1 As shown, the first steel beam 4 is located on the left side of the floor formwork 1, and the second steel beam 5 is located on the right side of the floor formwork 1. The left end face of the floor formwork 1 abuts against the web plate 8 of the first steel beam 4, and the right end face of the floor formwork 1 abuts against the left end face of the upper flange plate 6 of the second steel beam 5. Before pouring, a steel reinforcement structure will be laid on the upper end face of the floor formwork 1. After the reinforcement structure is laid, the pouring can proceed.

[0035] In some embodiments, a sealing structure 9 is provided at the abutment of the bottom formwork 1 and the web plate 8 of the first steel beam 4, and a sealing structure 9 is provided at the abutment of the bottom formwork 1 and the upper flange plate 6 of the second steel beam 5.

[0036] In this embodiment, as Figure 1 As shown, the sealing structure 9 can seal the gap between the bottom formwork 1 and the web plate 8 of the first steel beam 4, as well as the gap between the bottom formwork 1 and the upper flange plate 6 of the second steel beam 5, to prevent the concrete at the top of the bottom formwork 1 from leaking through the gap and causing grout leakage.

[0037] Preferably, in this embodiment, the sealing structure 9 is a sealant. After the first support member 2 and the second support member 3 are erected, the floor formwork 1 is placed on top of the second support member 3. Then, sealant is filled into the gaps at the contact points between the floor formwork 1 and the web plate 8 of the first steel beam 4, and between the floor formwork 1 and the upper flange plate 6 of the second steel beam 5 for sealing.

The first column 201 is set in the cavity of the first steel beam 4, and the second column 202 is set in the cavity of the second steel beam 5. The height of the first column 201 is greater than that of the second column 202. The top of the first column 201 and the top of the second column 202 are located on the same plane. The two ends of the second support member 3 are fixedly connected to the top of the first column 201 and the top of the second column 202, respectively.

[0039] Specifically, the height of the first steel beam 4 is greater than that of the second steel beam 5, and the cavity of the first steel beam 4 is also greater than that of the second steel beam 5. The height of the first column 201 inside the first steel beam 4 is greater than that of the second column 202 inside the second steel beam 5. The top of the first column 201 and the top of the second column 202 are located on the same horizontal plane. The left and right ends of the second support member 3 overlap and are fixedly connected to the top of the first column 201 and the top of the second column 202, respectively, so that the second support member 3 is set horizontally and parallel. The upper surface of the second support member 3 is flat, and the floor template 1 placed on the second support member 3 is also set horizontally and parallel.

[0040] Preferably, in this embodiment, the first column 201, the second column 202, and the second support member 3 are made of timber. The timber can be cut to the required length to meet construction requirements. Using timber can effectively reduce costs, and its light weight makes it easy for construction personnel to transport and handle.

[0041] In this embodiment, the top of the floor formwork 1 is reinforced with steel bars. When the floor slab is poured, the steel bars laid on the top of the floor formwork 1 will be poured into the floor slab.
