Technical Field
[0001] This utility model relates to the field of assembled floor slab technology, and in particular to a reinforced concrete assembled floor slab. Background Technology
[0002] Reinforced concrete is a composite building material composed of concrete and steel bars. Through the synergistic effect of the two, they give full play to their respective advantages to form a structural system with high strength, high durability and good seismic performance. Reinforced concrete precast floor slabs are a floor slab system that is quickly assembled on the construction site using precast components. It combines the precision advantages of industrialized production with the construction efficiency of on-site assembly. It has the characteristics of standardization, modularization and short construction cycle. During construction, multiple precast floor slabs need to be spliced together and then the upper layer of concrete is poured on top of the precast floor slabs.
[0003] In existing technologies, the lack of connecting structures between precast floor slabs during the assembly and splicing process results in significant gaps between them, leading to poor overall structural integrity. This affects the overall stability of the building structure, increases the risk of quality problems such as cracks and deformation, and poses a potential threat to the safety of the building. Therefore, it is necessary to develop a reinforced concrete precast floor slab to solve these problems. Utility Model Content

The precast floor slab body is provided on the top of the base. Fixing components are provided on both sides of the precast floor slab body to facilitate fixing the precast floor slab body to the base. A slot is provided on the precast floor slab body. A connecting block is provided inside the slot. A fixing plate is fixedly connected to the right end of the connecting block. A first screw is fixedly connected to the left end of the connecting block. A limit plate is provided on the first screw. A nut for fixing the limit plate is threaded to the outside of the first screw.
[0006] Preferably, there are two first screws, which are symmetrically distributed on the left end of the connecting block.

[0011] Preferably, the second screw has a matching annular groove at the corresponding position of the rotating block, and the rotating block is rotatably connected in the annular groove of the second screw.
[0012] The beneficial effects of this utility model are:
[0013] Compared to the lack of connecting structures between precast floor slabs, this method uses connecting blocks inserted into slots within the precast floor slab bodies to splice two precast floor slab bodies. Fixing and limiting plates then restrict the spliced slab bodies, improving the flatness of the splice and preventing gaps between them. This enhances the overall integrity of the floor slab, improves the practicality of the device, and avoids the problem of significant gaps between precast floor slabs, which can lead to poor structural integrity and affect the overall stability of the building.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 - Figure 6 This utility model provides an embodiment: a reinforced concrete precast floor slab, including a base 1, which further includes a precast floor slab body 21 and fixing components. The precast floor slab body 21 is provided on the top of the base 1. Fixing components are provided on both sides of the precast floor slab body 21 to facilitate fixing the precast floor slab body 21 to the base 1. A slot 24 is provided on the precast floor slab body 21. A connecting block 25 is provided inside the slot 24. A fixing plate 26 is fixedly connected to the right end of the connecting block 25. A first screw 27 is fixedly connected to the left end of the connecting block 25. A limit plate 28 is provided on the first screw 27. The outside of the first screw 27... The threaded connection includes a nut 29 for fixing the limiting plate 28. By aligning and inserting the connecting block 25 into the slot 24 of the precast floor slab body 21, the two precast floor slab bodies 21 are spliced together. The fixing plate 26 and the limiting plate 28 limit the spliced two precast floor slab bodies 21, thereby improving the splicing flatness of the two precast floor slab bodies 21 and preventing movement gaps between the precast floor slab bodies 21, thus improving the integrity of the entire floor slab. The fixing component presses and fixes the spliced precast floor slab body 21 to the base 1, thereby improving the stability of the grouting and enhancing the practicality of the device.
[0024] Please see Figure 2 - Figure 4In this embodiment, two first screws 27 are provided, symmetrically distributed on the left end of the connecting block 25, which facilitates the positioning of the limiting plate 28 and improves the stability of the installation of the limiting plate 28. The limiting plate 28 has corresponding through holes at the corresponding positions of the two first screws 27. The first screws 27 are placed in the through holes of the limiting plate 28, which facilitates the installation of the limiting plate 28 and the connecting block 25, improving the flatness when splicing the two precast floor slab bodies 21 and improving the stability of the grouting. The top of the precast floor slab body 21 is fixedly connected to a lifting ring 22 for easy lifting and moving of the precast floor slab body 21. A lifting ring 22 is fixedly connected to the precast floor slab body 21 to improve the stability of the grouting. A high-strength threaded steel bar 23 is used to splice two precast floor slab bodies 21 by aligning and inserting the connecting block 25 into the slot 24 of the precast floor slab body 21. The fixing plate 26 and the limiting plate 28 limit the spliced two precast floor slab bodies 21, thereby improving the splicing flatness of the two precast floor slab bodies 21, preventing the movement gap between the precast floor slab bodies 21, improving the integrity of the entire floor slab, and improving the practicality of the device. Four lifting rings 22 are provided, which are symmetrically distributed on the top of the precast floor slab body 21, making it convenient to lift the precast floor slab body 21, making it convenient to move the precast floor slab body 21, and improving the efficiency of splicing between the precast floor slab bodies 21.
[0025] Please see Figure 5 - Figure 6 In this embodiment, the fixing component includes a threaded hole 31, which is formed on the base 1. A second screw 32 is threadedly connected inside the threaded hole 31. A knob 33 for easy rotation is fixedly connected to the top of the second screw 32. A rotating block 34 is rotatably connected to the second screw 32. A pressure plate 35 for pressing and fixing the precast floor slab body 21 is fixedly connected to the outside of the rotating block 34. The fixing component moves the pressure plate 35 downward by screwing the second screw 32 into the threaded hole 31. It presses and fixes the precast floor slab body 21 after splicing to the base 1, thereby improving the stability of the grouting and the practicality of the device. The second screw 32 has a matching annular groove at the corresponding position of the rotating block 34. The rotating block 34 is rotatably connected in the annular groove of the second screw 32, so that the pressure plate 35 rotates on the second screw 32 through the rotating block 34. While rotating the second screw 32, the pressure plate 35 is limited by holding the pressure plate 35 by hand, so that it presses the precast floor slab body 21.
[0026] During operation, the two precast floor slab bodies 21 to be connected are placed on top of the base 1. The end of the connecting block 25 away from the fixing plate 26 is aligned with the slot 24 of the two precast floor slab bodies 21. The connecting block 25 is then pushed into the slot 24 of the precast floor slab body 21. The fixing plate 26 is brought into contact with one side of the two precast floor slab bodies 21 to splice the two precast floor slab bodies 21. At this time, the limiting plate 28 is aligned and passed through the two first screws 27 to connect with the other end of the two precast floor slab bodies 21. When the nut 29 is screwed onto the outside of the first screw 27, the limiting plate 28 and the connecting block 25 are installed, thus fixing the splicing of the two precast floor slab bodies 21 and improving the integrity of the precast floor slab bodies 21 during pouring. By aligning the second screw 32 and screwing it into the threaded hole 31 of the base 1, while holding the pressure plate 35, the knob 33 is screwed in, causing the pressure plate 35 to move downward, pressing the precast floor slab body 21 and fixing it, thus improving the stability of the pouring.
[0027] Through the above steps, by aligning and inserting the connecting block 25 into the slot 24 of the precast floor slab body 21, the two precast floor slab bodies 21 are spliced together. The fixing plate 26 and the limiting plate 28 limit the spliced two precast floor slab bodies 21, thereby improving the splicing flatness of the two precast floor slab bodies 21, preventing the movement gap between the precast floor slab bodies 21, improving the integrity of the entire floor slab, and improving the practicality of the device. This solves the problem of obvious movement gaps between the precast floor slabs, which results in poor integrity of the entire floor slab structure and affects the overall stability of the building structure.
