Then, the concrete panel 104 is poured on the upper surface of the main ribbed floor slab body 102 again, so as to facilitate the installation of the ribbed floor slab main body 100 on the upper surface of the prefabricated assembled box for use. The following are further provided on the ribbed floor slab main body 100:

[0025] A strengthened support connection mechanism, and this strengthened support connection mechanism includes a strengthened support connection component arranged at the connection between the interior of the main ribbed floor slab body 102 and the upper surface of the precast bottom slab 101. Fixed installation components are arranged at the ends and the middle positions of the strengthened support connection component. When the ribbed floor slab main body 100 is installed and used, after the main ribbed floor slab body 102 is closed on the surface of the precast bottom slab 101, the strengthened support connection mechanism strengthens and supports between the main ribbed floor slab body 102 and the precast bottom slab 101, improving the stability of the strengthened support connection during the installation and use of the ribbed floor slab main body 100 on the upper surface of the prefabricated assembled box.

[0026] In order to facilitate the strengthened support installation between the main ribbed floor slab body 102 and the precast bottom slab 101 through the strengthened support connection component, in this embodiment, preferably, the strengthened support connection component includes a reinforcement support frame 1011 arranged inside the main ribbed floor slab body 102. The lower surface of the reinforcement support frame 1011 contacts the surface of the precast bottom slab 101. Fixed closing plates 1012 are integrally formed at both ends of the reinforcement support frame 1011. The fixed closing plates 1012 contact the inner surface of the main ribbed floor slab body 102. After the reinforcement support frame 1011 is closed on the surface of the precast bottom slab 101, the main ribbed floor slab body 102 can be closed on the surface of the precast bottom slab 101 and installed and used through the reinforcement support frame 1011, making the strengthening and fixing more stable during use.

After the threaded rod 1024 is penetrated through the inside of the connecting steel plate 1021 and rotationally fixed to the inside of the internal threaded cylinder 1022, the fixing nut 1025 is rotated inside the connecting steel plate 1021 at the end of the threaded rod 1024 again to tighten the threaded rod 1024, so as to be used for re-reinforcing and installing after pouring between the main multi-ribbed floor body 102 and the rib beam body 103.

[0032] The working principle and usage process of the present utility model: When installing and using this prefabricated assembled box multi-ribbed floor, first fix the precast bottom plate 101 on the upper surface of the prefabricated assembled box. Then, close the main multi-ribbed floor body 102 on the upper surface of the precast bottom plate 101. Pour concrete between the sides of the two main multi-ribbed floor bodies 100 and let it soak into the internal shear groove 105 to form the rib beam body 103. Then, pour the concrete panel 104 on the upper surface of the main multi-ribbed floor body 102, so as to facilitate the installation of the main multi-ribbed floor body 100 on the upper surface of the prefabricated assembled box for use.

[0033] Then, before installing the main multi-ribbed floor body 100, after the precast bottom plate 101 is fixedly installed, close the reinforcement support frame 1011 on the surface of the precast bottom plate 101 and rotate the bottom fixing bolt 1013 for fixed installation. Then, after closing the main multi-ribbed floor body 102 on the surface of the precast bottom plate 101, make the fixed closing plate 1012 contact with the inner surface of the main multi-ribbed floor body 102, and rotate the side fixing bolt 1014 to embed it into the internal threaded hole 1015 to fix the fixed closing plate 1012 and the reinforcement support frame 1011, so as to strengthen the connection after the reinforcement support frame 1011 is fixedly installed and the main multi-ribbed floor body 102 is closed with the precast bottom plate 101. Then, pour concrete on the sides of the two main multi-ribbed floor bodies 100, so as to facilitate the reinforcement between the precast bottom plate 101 and the main multi-ribbed floor body 102 after the main multi-ribbed floor body 100 is closed and installed, and make it more stable when the upper surface is subjected to gravity, and improve the stability of the strengthened support connection when the main multi-ribbed floor body 100 is installed on the upper surface of the prefabricated assembled box.

[0034] Finally, when the ribbed floor slab main body 100 is pouring the rib beam body 103 after installation, close the connecting steel plate 1021 at both ends of the connection of the two main ribbed floor slab bodies 102, and pour and fix the connecting steel plate 1021 inside the rib beam body 103. At the same time, when prefabricating the main ribbed floor slab body 102, pour and fix the internal threaded column body 1022 on both sides inside the main ribbed floor slab body 102. After closing, pass the threaded rod 1024 through the side of the connecting steel plate 1021 and rotate and fix it inside the internal threaded column body 1022. Then, rotate and fix the nut 1025 at the end of the threaded rod 1024 inside the connecting steel plate 1021 to tighten the threaded rod 1024. When tightening, the limiting ring 1023 strengthens the limit of the internal threaded column body 1022 and is not easy to loosen, so as to reinforce and install the main ribbed floor slab body 102 and the rib beam body 103 again after pouring. After installation, it is more stable to use, and the fixing between the two main ribbed floor slab bodies 102 is strengthened when the ribbed floor slab main body 100 is installed on the prefabricated assembly box.
