When laying pipelines and other lines between floors, a large amount of time is required for operation. Moreover, the self-weight of the concrete floor slab is large and the seismic resistance is poor, which is likely to cause greater personal and property damage in the event of an accidental collapse accident. For this reason, we propose an assembled floor slab. Summary of the Utility Model

A filling layer is also laid inside the shaping frame, and the threaded steel bars are arranged inside the filling layer. Reinforcing components are arranged at the four corners of the shaping frame; the reinforcing components include inclined threaded columns arranged at the four corners of the shaping frame, and both ends of the threaded columns respectively penetrate through the corresponding positions on the shaping frame and extend outside the shaping frame. Limiting nuts are threadedly connected to both ends of the threaded columns located outside the shaping frame.

[0006] Preferably, extension blocks are fixedly installed at the positions corresponding to the ends of the threaded columns on the outer wall of the shaping frame, and the ends of the threaded columns penetrate through the inside of the extension blocks.

[0007] Preferably, assembly bars are movably installed on both the upper and lower sides of the shaping frame. A plurality of mounting holes are formed through the assembly bars, and fastening screws for connecting the assembly bars and the shaping frame are movably installed inside the plurality of mounting holes.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1 - 3 shown, a prefabricated floor slab includes a shaping frame 1. A plurality of threaded steel bars 3 are fixedly installed inside the shaping frame 1. A filling layer 2 is also laid inside the shaping frame 1, and the threaded steel bars 3 are arranged inside the filling layer 2. Reinforcing components are provided at the four corners of the shaping frame 1; the reinforcing components include inclined threaded columns 10, which are arranged at the four corners of the shaping frame 1 and both ends of the threaded columns 10 respectively penetrate through the corresponding positions on the shaping frame 1 and extend outside the shaping frame 1. Limit nuts 9 are threadedly connected to both ends of the threaded columns 10 located outside the shaping frame 1.

[0024] In practical applications, the filling layer 2 is composed of multiple functional layers such as a heat preservation layer, a sound insulation layer, and a fire prevention layer. The user sets the filling layer 2 inside the shaping frame 1. Among them, the threaded columns 10 and the plurality of threaded steel bars 3 are both arranged inside the filling layer 2. The setting of the plurality of threaded steel bars 3 can enhance the overall strength of the floor slab, and the threaded columns 10 arranged at the four corners of the shaping frame 1 can be used to enhance the structural strength of the four corners of the shaping frame 1 and prevent situations such as loosening and fracture at the four corners of the shaping frame 1.

[0025] As Figure 3 shown, extension blocks 8 are fixedly installed at the corresponding positions of the outer wall of the shaping frame 1 and the ends of the threaded columns 10, and the ends of the threaded columns 10 penetrate through the inside of the extension blocks 8; the extension blocks 8 are wedge-shaped. The setting of the extension blocks 8 can fill the angle formed between the threaded columns 10 and the outer wall of the shaping frame 1, facilitating the fastening of the limit nuts 9 threadedly connected to the ends of the threaded columns 10 to the threaded columns 10.

[0026] As Figure 2 and Figure 3 shown, assembly bars 4 are movably installed on both the upper and lower sides of the shaping frame 1. A plurality of mounting holes 5 are penetrated through the assembly bars 4, and fastening screws 7 for connecting the assembly bars 4 and the shaping frame 1 are movably installed inside the plurality of mounting holes 5; the plurality of fastening screws 7 are respectively arranged at both ends of the reinforcing bars 6. The ends of the fastening screws 7 penetrate through the inside of the reinforcing bars 6 and the assembly bars 4 and then are threadedly connected to the corresponding positions on the shaping frame 1.

[0027] As Figure 2As shown in the figure, two sets of reinforcing bars 6 are symmetrically installed on the assembly bar 4. Each set of reinforcing bars 6 includes two reinforcing bars 6, and the two reinforcing bars 6 are arranged in a cross shape. The ends of the two reinforcing bars 6 are also movably connected to the assembly bar 4 by fastening screws 7. The two sets of cross-shaped reinforcing bars 6 are arranged at both ends of the assembly bar 4, which can strengthen the overall structure after the combination of the assembly bar 4 and the shaping frame 1.

[0028] As Figure 2 shown in the figure, the assembly bar 4 includes a loop frame, and a plurality of equally spaced rectangular bars are fixedly installed inside the loop frame. The length and width of the assembly bar 4 are the same as those of the shaping frame 1. The assembly bar 4 is integrally hollowed out, and the plurality of equally spaced rectangular bars can enhance the enclosure effect of the assembly bar 4 on the filling layer 2.

[0029] As Figure 3 shown in the figure, the extension block 8 is wedge-shaped, and one outer wall of the extension block 8 is perpendicular to the threaded column 10. The setting of the extension block 8 can make the outer wall of the limit nut 9 provided at the end of the threaded column 10 fit with the outer wall of the extension block 8, thereby making the fastening effect of the limit nut 9 on the threaded column 10 better.

[0030] As Figure 2 shown in the figure, the distance between adjacent steel bars 3 is between 50 and 100 cm. The number of steel bars 3 is determined according to the width of the shaping frame 1. The spacing of 50 to 100 cm can reduce the self-weight of the floor slab while ensuring the strength of the floor slab.

[0031] The working principle of the utility model: When in use, the filling layer 2 is laid inside the shaping frame 1, and the steel bars 3 are arranged inside the filling layer 2. Threaded columns 10 are provided at the four corners of the shaping frame 1. The threaded columns 10 and the two side frames of the shaping frame 1 together form a stable triangular structure, which can prevent the four corners of the shaping frame 1 from deforming and breaking, thereby making the overall structure of the shaping frame 1 more stable and the overall structure strength of the floor slab higher. Assembly bars 4 are provided on both sides of the shaping frame 1. The setting of the assembly bars 4 can prevent the filling layer 2 in the steel bars 3 from becoming loose after long-term use due to aging. Two sets of reinforcing bars 6 are provided on the outer wall of the assembly bar 4. The cross-shaped reinforcing bars 6 can reinforce the whole shaping frame 1 and prevent the whole shaping frame 1 from deforming.
