Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a bottom connection mechanism for prefabricated buildings. Background Technology

[0002] Prefabricated buildings are assembled on-site using prefabricated components (such as floor slabs and wall panels) from factories. They are mainly divided into five categories: block buildings, panel buildings, box-type buildings, frame panel buildings, and lift-slab and lift-floor buildings. The bottom connection mechanism is used to fix the prefabricated components to the ground or other load-bearing structures, and its stability directly affects the safety of the building.

[0003] Most existing mechanisms are designed to fix support columns of a fixed shape. However, for support columns of different shapes, it is necessary to install mounting frames corresponding to the support columns in order to fix them. This not only increases construction costs but also leads to low installation efficiency. Therefore, we propose a prefabricated building bottom connection mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bottom connection mechanism for prefabricated buildings, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building bottom connection mechanism, comprising a foundation and a mounting base. A base is fixedly installed at the top of the foundation, and a slot is formed inside the base. A sliding groove is formed inside the base, and a slider is slidably connected inside the sliding groove. A movable plate is fixedly installed on one side of the slider, and a fixing screw is threadedly connected inside the movable plate. A first screw hole is formed at the bottom of the base, and the first screw hole is located at the bottom of the slot. An extension plate is fixedly installed on the outside of the mounting base, and a third screw hole is formed inside the extension plate. Both the first screw hole and the third screw hole mate with the fixing screw. A mounting frame is fixedly installed at the top of the mounting base, and a mating component is provided inside the mounting frame. Through the mating component, triangular auxiliary parts, L-shaped auxiliary parts, and square auxiliary parts can be placed inside the mounting frame, thus accommodating support columns of different shapes and fixing them. This process makes the device more versatile.

[0006] Preferably, the mating assembly includes four triangular auxiliary parts.

[0007] Preferably, the mating assembly includes four L-shaped auxiliary parts.

[0008] Preferably, the mating assembly includes two square auxiliary parts.

[0009] Preferably, a fixing screw is fixedly installed at the top of the base, and a fastening nut and a locking nut are threadedly connected to the outside of the fixing screw. A second screw hole is opened inside the mounting base, which mates with the fixing screw. An anti-slip pad is fixedly installed at the top of the mounting base, and a reinforcing rib is fixedly installed at the top of the mounting base. One side of the reinforcing rib is fixedly connected to one side of the mounting frame. By setting the fixing screw, the mounting base and the base can be fixed in the first layer.

[0010] Preferably, the mounting frame has several fixing holes on its outer side.

[0011] This utility model provides a bottom connection mechanism for prefabricated buildings, which has the following advantages:

[0012] 1. The bottom connection mechanism of this prefabricated building can fix circular support columns, square support columns, and I-shaped support columns respectively by placing triangular auxiliary parts, L-shaped auxiliary parts, and square auxiliary parts inside the installation frame. This process makes the device more versatile, can adapt to support columns of more shapes, and fix them, while increasing the installation efficiency of workers.

[0013] 2. The bottom connection mechanism of this prefabricated building can lock the extension plate by setting the movable plate, and then use the fixing screws to cooperate with the third screw hole and the first screw hole in sequence to fix the entire mounting base on the base. Through this process, the mounting base can be more stably fixed on the base. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a prefabricated building bottom connection mechanism, including a foundation 1 and a mounting base 11. A base 2 is fixedly installed at the top of the foundation 1. A slot 3 is opened inside the base 2. A sliding groove 4 is opened inside the base 2. A slider 5 is slidably connected inside the sliding groove 4. A movable plate 6 is fixedly installed on one side of the slider 5. A fixing screw 7 is threadedly connected inside the movable plate 6. The fixing screw 7 is used to fix the extension plate 15 and the base 2. A first screw hole 201 is opened at the bottom of the base 2, and the first screw hole 201 is located at the bottom of the slot 3. An extension plate 15 is fixedly installed on the outside of the mounting base 11. A third screw hole 151 is opened inside the extension plate 15. Both the first screw hole 201 and the third screw hole 151 are engaged with the fixing screw 7. A mounting frame 13 is fixedly installed at the top of the mounting base 11. The mounting frame 13 is used to fix the support column. A mating component is provided inside the mounting frame 13.

[0022] like Figure 2 As shown, the assembly includes four triangular auxiliary parts 16, which are used to fix the circular tube.

[0023] like Figure 3 As shown, the assembly includes four L-shaped auxiliary parts 17, which are used to fix the square tube.

[0024] like Figure 4 As shown, the mating assembly includes two square auxiliary parts 18, and the square auxiliary parts 16 are used to fix the I-shaped tube.

[0025] like Figure 1As shown, a fixing screw 8 is fixedly installed at the top of the base 2. A fastening nut 9 and a locking nut 10 are threadedly connected to the outside of the fixing screw 8. The fastening nut 9 is used to fix the mounting seat 11 on the base 2, and the locking nut 10 is used to prevent the fastening nut 9 from moving backward. A second screw hole 111 is opened inside the mounting seat 11, which cooperates with the fixing screw 8. An anti-slip pad 12 is fixedly installed at the top of the mounting seat 11 to prevent the fastening nut 9 from becoming too tight. A reinforcing rib 14 is fixedly installed at the top of the mounting seat 11 to strengthen the connection between the mounting frame 13 and the mounting seat 11. One side of the reinforcing rib 14 is fixedly connected to one side of the mounting frame 13. Through the setting of the fixing screw, the mounting seat and the base can be fixed in the first layer.

[0026] like Figure 1 As shown, the mounting frame 13 has several fixing holes 131 on its outer side. The fixing holes 131 are used to cooperate with external screws to fix the support column.

[0027] In summary, the bottom connection mechanism of this prefabricated building, when in use, firstly, the base 2 is fixed on the foundation 1, then the mounting base 11 is placed inside the base 2, and the second screw hole 111 and the fixing screw 8 are engaged. Then, the worker screws the fastening nut 9 and the anti-reverse nut 10 onto the fixing screw 8 in sequence, thus securing the mounting base 11 for the first layer. Then, the moving plate 6 is pushed, and the fixing screw 7 is tightened, so that the fixing screw 7 engages with the third screw hole 151 and the first screw hole 201, thus securing the mounting base 11 for the second layer, thereby ensuring stronger stability of the device during use. Finally, the support column can be placed inside the mounting frame 13. The support column is then fitted to the mounting frame 13 using external screws and fixing holes 131. However, when the support column has a different shape, such as a circular support column, triangular auxiliary parts 16 are placed at the four corners inside the mounting frame 13 before inserting the circular support column. When the support column is square, L-shaped auxiliary parts 17 are placed at the four corners inside the mounting frame 13. Finally, when encountering an I-shaped support column, a square auxiliary part 18 is placed inside the mounting frame 13. After the support column is placed inside the mounting frame 13, it can be fixed by using external screws and fixing holes 131. The above is the working principle of this utility model.
