[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, an integrated structure of floor slab and beam of the present invention comprises a shell 2 sleeved on the beams 1 on both sides, a U-shaped groove for concrete to enter is formed between the shell 2 and the beam 1, a bottom plate 3 is installed between the shell 2, the opposite end of the shell 2 protrudes upward to form a connecting portion 11, a frame 4 is sleeved on the outside of the connecting portion 11, a casting cavity matching the floor slab is formed between the frame 4, the shell 2 and the bottom plate 3, the casting cavity is connected to the U-shaped groove, a scraper 8 is provided on the outside of the opening of the frame 4, and a fixing part for connecting the scraper 8, the frame 4 and the shell 2 together is installed on the scraper 8.

[0028] In this embodiment, positioning grooves are vertically provided at both ends of the inner cavity of the frame 4. The outer side surface of the connecting portion 11 protrudes opposite the positioning groove to form a positioning portion 10. The positioning portion 10 is slidably set in the positioning groove. The outer side surface of the positioning portion 10 is provided with a first screw hole 12.

[0029] In this embodiment, the fixing member includes a plurality of fixing plates 5 and a plurality of positioning rods 7. Slots 9 are provided at both ends of the frame 4. The fixing plates 5 are all arranged in the slots 9. The scraper 8 is provided with a plurality of positioning holes. The positioning rods 7 are all arranged in the positioning holes. Both ends of the positioning rods 7 are bent and mounted on the fixing plates 5.

[0030] A second screw hole is provided on the outer side surface of the fixing plate 5 opposite to the first screw hole 12, and a third screw hole is provided on the inner wall surface of the slot 9 opposite to the first screw hole 12. Bolts 6 for connecting the fixing member, the frame 4 and the housing 2 are threadedly connected in the first screw hole 12, the second screw hole and the third screw hole.

[0031] The shell, frame and scraper can be directly fixed together by bolts on both sides, which facilitates assembly efficiency.

[0032] In this embodiment, rectangular openings 13 are provided on both sides of the shell 2 , and the shell 2 is sleeved on the beam 1 through the rectangular openings 13 , and the inner side surfaces of the rectangular openings 13 are in contact with the outer side surfaces of the beam 1 .

[0033] In this embodiment, one end of the scraper 8 is placed on the end surface of the frame 4. After the concrete is poured, the scraper can move back and forth along the positioning rod, thereby smoothing the surface of the concrete.

[0034] In this embodiment, the shell 2 and the base plate 3 are integrally formed. The shell 2, the base plate 3 and the frame 4 are all made of aluminum alloy material, and high-strength aluminum alloy (such as 6061-T6) is used. It is light in weight and corrosion-resistant, and is suitable for standardized buildings.

[0035] In this embodiment, the open end surface of the top of the shell 2 is flush with the top surface of the beam 1, so that the bottom surface of the floor slab after casting can solidify together with the beam to ensure the contact area between the floor slab and the beam.

[0036] In this embodiment, the end surface of the frame 4 away from the scraper 8 is arranged to contact the upper opening end surface of the shell 2 and the surface of the bottom plate 3, thereby improving the sealing between the frame, the shell and the bottom plate.

[0037] In this embodiment, the width of the frame 4 matches the width of the bottom plate 3 and the wide body, so that both sides of the floor slab after casting are arranged flush, avoiding unevenness.

[0038] When in use, the shell is sleeved on the beams on both sides from bottom to top through the rectangular opening. After sleeved, support members are installed between the bottom plate and the bottom of the shell and the ground.

[0039] The frame can be sleeved on the connecting parts on both sides. During the sleeve process, the positioning part can be slidably set in the positioning slot of the frame. After the fixing plate is inserted into the slot, the first screw hole, the second screw hole and the third screw hole can be arranged relative to each other, so that the bolt can be threadedly connected to the first screw hole, the second screw hole and the third screw hole, thereby fixing the scraper, the frame and the shell together, and the shell can be fixed on the beam through the frame to ensure the stability of the installation;

[0040] After the above is completed, the concrete can be poured into the casting cavity, and the concrete part that has entered can enter the U-shaped groove. After the concrete is vibrated evenly by the vibrator, the scraper can be pushed along the positioning rod to scrape off the excess concrete on the surface of the frame and make the surface of the concrete smooth.

[0041] Among them, as the concrete enters the U-shaped groove, after the concrete solidifies to form a floor slab, a wrap-like connection part is provided between the two ends of the floor slab and the beam, which increases the connection strength between the floor slab and the beam. Among them, after multiple floor slabs are cast, concrete can be poured again in the gaps between the floor slabs to ensure the strength and flatness of each subsequent floor.

[0042] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
