Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a precast composite floor slab. Background Technology

[0002] During the construction process, precast concrete composite floor slabs are required. Composite floor slabs are assembled monolithic floor slabs made by stacking precast slabs and cast-in-place reinforced concrete layers.

[0003] A search revealed a utility model patent in China with patent publication number CN215888774U, which discloses a precast concrete composite floor slab. The slab is described as comprising a frame, a sound insulation board, and partitions. Longitudinal joists are welded and fixed within the frame, and transverse joists are welded and fixed within the frame. During use, the sound insulation board, laid inside the frame, enhances the sound insulation of the precast concrete composite floor slab and reduces its weight, improving its performance. Connecting protrusions on one side of the frame and connecting grooves on the other side allow for better splicing between adjacent composite floor slabs, improving splicing quality and thus construction quality. However, this device still has some shortcomings, such as poor splicing effect, difficulty in reinforcement and fixing, and the frame's tendency to shift and create gaps, affecting the overall support performance, stability, and robustness of the composite floor slab. Therefore, we propose a precast composite floor slab. Utility Model Content

[0015] Example

[0016] Please see Figures 1-4 A precast composite floor slab, comprising a floor slab body 1, and further comprising: Splicing block 2 is fixedly connected to the main body of the floor slab 1; Splicing groove 3 is formed on the main body of the floor slab 1, and splicing block 2 is adapted to splicing groove 3; Two connecting mechanisms are provided, both on the splicing block 2 and the splicing groove 3. Each connecting mechanism includes two connecting grooves and two through holes 4. The two through holes 4 are both located on the splicing block 2, and the two connecting grooves are both located on the floor slab body 1. Each of the two connecting grooves has two through holes 5. A connecting plate 6 is placed in the connecting groove, and two through holes 3 are located on the connecting plate 6. The four through holes 2 and 5 are grouped in pairs, and the four through holes 3 are grouped in pairs. Fixing bolts 7 are placed in the two through holes 2 and 5 and the two through holes 3. The fixing bolts 7 are adapted to the through holes 1 and 4. Fixing nuts 8 are threaded on the fixing bolts 7. The fixing bolts 7 are used to pass through the through holes 3, 2 and 5 and the through holes 1 and 4. The fixing nuts 8 and the fixing bolts 7 are used to lock the splicing block 2, ensuring the firmness of the splicing block 2 and the splicing groove 3 and preventing loosening. The reinforcement mechanism is installed on the main floor slab 1 and two connecting plates 6. The reinforcement mechanism includes a reinforcement groove 9, a reinforcement block 10, an opening 11, and two openings 2. The opening 11 is opened on the splicing block 2, and the two openings 2 are both opened on the main floor slab 1. The openings 2 are connected to the splicing groove 3 and the connecting groove. The reinforcement groove 9 and the reinforcement block 10 are adapted to each other and are fixedly connected to the two connecting plates 6 respectively. The reinforcement groove 9 and the reinforcement block 10 are adapted to the opening 11 and the opening 2. The reinforcement groove 9 and the reinforcement block 10 can enter the opening 11 and the opening 2 to lock the splicing block 2 and further reinforce the splicing joint.

[0017] Two limiting tubes 12 are fixedly connected to one of the connecting plates 6. The fixing nut 8 is located inside the limiting tube 12 and is used to limit the nut to prevent the nut from rotating and loosening.

[0018] One of the connecting slots contains a cover plate 13, which has two limiting slots. One end of the fixing bolt 7 is located in the limiting slot. The cover plate 13 and the limiting slots are used to cover the fixing bolt 7 and limit the fixing bolt 7 to prevent it from loosening.

[0019] One of the connecting plates 6 and the reinforcing block 10 has a threaded groove 14, and a mounting bolt 15 is provided through the cover plate 13. The mounting bolt 15 is threaded into the threaded groove 14 and is used to fix the cover plate 13.

[0020] The cover plate 13 has a hidden groove 16, and one end of the mounting bolt 15 is located in the hidden groove 16 to prevent the mounting bolt 15 from protruding.

[0021] In summary, the working principle and process of this precast composite floor slab are as follows: First, the precast composite floor slab is placed at the desired location. Then, the two floor slab bodies 1 are positioned, and the splicing block 2 is inserted into the splicing groove 3. Two connecting plates 6 are then placed into the connecting groove, allowing the reinforcing groove 9 and the reinforcing block 10 to enter the corresponding opening 2. One end of the reinforcing block 10 is inserted into the reinforcing groove 9. At this point, both the reinforcing block 10 and the reinforcing groove 9 are located within opening 11, limiting the splicing block 2. After the through holes 1 4, 2 5, and 3 are aligned, the fixing bolts 7 are inserted into the through holes 1 4, 2 5, and 3. Then, the fixing nuts 8 are inserted into the limiting tube 12, and the fixing bolts 7 are rotated to thread the fixing bolts 7 and nut 8 together. In this way, the splicing block 2 and the splicing groove 3 can be connected and fixed. Then, the cover plate 13 is put on, so that the fixing bolt 7 is locked in the limiting groove. The installation bolt 15 is threaded into the threaded groove 14, which can fix the cover plate 13. By limiting the fixing bolt 7, the fixing bolt 7 is prevented from loosening. The floor slab body 1 involved in this solution is the authorized technology disclosed in the utility model patent with Chinese patent publication (announcement) number CN215888774U. Its internal structure and working principle are well known to those skilled in the art and are not the innovation of this patent. The innovation of this patent lies in the splicing and reinforcement of the floor slab body 1 to improve the support performance, stability and firmness. Therefore, this patent will not describe its internal structure and working principle in detail.

[0022] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
