[0030] Example:

[0031] like Figure 1-4As shown, this embodiment proposes an assembled precast composite slab, including a slab body 1. An assembly base 2 is fixedly installed on the front of the slab body 1. A rectangular groove 3 is formed on the front of the assembly base 2 for assembling two slab bodies 1. A filling port 4 is formed on the top of the assembly base 2 for filling concrete. There are three filling ports 4. An assembly connecting plate 5 is fixedly installed on the back of the slab body 1. The assembly connecting plate 5 on the back of one slab body 1 is inserted into the assembly base 2 on the front of another slab body 1, so that the assembly connecting plate 5 is inserted through the rectangular groove 3 on the assembly base 2. A filling groove 6 is formed on the top of the assembly connecting plate 5, and concrete is poured in through the filling port 4. The concrete flows into the filling tank 6. The slab 1 is equipped with reinforcing bars 7, which are arranged in a wavy shape. By arranging the reinforcing bars inside the slab 1 in a wavy shape, the contact area between the reinforcing bars and the slab 1 is increased during manufacturing, resulting in higher strength. Protective rubber sleeves 8 are provided at both ends of the reinforcing bars 7 to prevent the ends of the reinforcing bars 7 from being scraped by workers. The top of the slab 1 has an arc surface 12. When concrete is poured on the surface of the slab 1, the concrete comes into contact with the arc surface 12, which increases the contact area between the concrete and the slab 1. After the concrete solidifies, it becomes more solid.

[0032] The rectangular slot 3 matches the assembly connecting plate 5. The assembly connecting plate 5 on the back of one plate 1 is inserted into the assembly base 2 on the front of another plate 1, so that the assembly connecting plate 5 is inserted through the rectangular slot 3 on the assembly base 2. The assembly connecting plate 5 is provided with a threaded groove 10.

[0033] Concrete is poured into the filling port 4 and flows into the filling tank 6. The filling port 4 is matched with the filling tank 6.

[0034] The locking mechanism includes a locking bolt 9 provided on the assembly base 2, which locks the two connected plates 1 together. The locking bolt 9 matches the threaded groove 10.

[0035] The connection mechanism includes a connecting frame 13 set on the top of the plate 1, which is used by workers to lay steel bars.

[0036] The protective pad mechanism includes a protective pad 11 disposed at the bottom of the plate 1 to prevent impact when the plate 1 is placed.

[0037] Specifically, when using this assembled precast composite slab: insert the assembly connecting plate 5 on the back of one slab 1 into the assembly seat 2 on the front of another slab 1, so that the assembly connecting plate 5 is inserted into the rectangular groove 3 on the assembly seat 2, and then fix it with locking bolts 9; when using, remove the protective rubber sleeve 8, which plays a protective role during transportation to prevent the ends of the reinforcing bars 7 from scratching the workers. When concrete needs to be poured after laying, pour the concrete from the filling port 4 and let the concrete flow into the filling groove 6. After the concrete solidifies, the connection between the two slabs 1 will be more fixed. When pouring concrete on the surface of the slab 1, the concrete contacts the arc surface 12 of the slab 1, which increases the contact area between the concrete and the slab 1. After the concrete solidifies, it will be more solid.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
