Description

Technical Field

[0001] This utility model relates to the field of building facilities technology, specifically a modular prefabricated building quick connection device. Background Technology

[0002] In the field of modern construction, with the acceleration of urbanization and the increasing demands for building efficiency and quality, rapid connection technology has gradually become a focus of industry attention. Traditional building connection methods often rely on on-site concrete pouring (see Chinese Patent CN106639298A), extensive welding, and complex bolt connection processes. On construction sites, these traditional connection methods face numerous problems. For example, on-site concrete pouring requires a long setting time, which not only delays the overall construction progress but is also easily affected by environmental factors such as weather, leading to unstable concrete quality and consequently affecting the safety of the building structure. While welding provides high connection strength, it is complex to operate, requires highly skilled workers, and poses safety hazards due to fumes and sparks generated during welding. Furthermore, subsequent weld inspection and maintenance are also cumbersome. Complex bolt connections require precise alignment and extensive manual operation, resulting in low installation efficiency and potential structural instability due to bolt loosening during long-term use. In addition, traditional connection methods struggle to achieve standardized and modular rapid assembly, hindering the large-scale promotion of industrialized construction and failing to meet the urgent needs of modern buildings for efficient, environmentally friendly, and high-quality rapid construction.

Several first plug-in posts are symmetrically installed on the outer walls of both sides of the connecting end pile in a vertically arranged uniform and equidistant manner. Each group of first plug-in posts has a first fixing screw hole on its outer wall.

[0007] A number of second plug-in posts are installed on one side of the modular connecting plate in a vertically arranged uniform and equidistant manner. A connecting socket with a size that matches the second plug-in post and is corresponding in position is opened on the side of the modular connecting plate away from the second plug-in post. A second fixing screw hole is opened on the outer wall of the second plug-in post. The modular connecting plate is connected to the connecting end pile and to each adjacent modular connecting plate by a first fixing bolt.

[0008] Preferably, the support leg is equipped with several sets of ground bolts for fixing it to the ground.

[0009] Preferably, the outer wall of the modular connecting plate is provided with a first through hole for installing the first fixing bolt.

[0029] Modular prefabricated building quick-connect device, such as Figures 1-3 As shown, the modular prefabricated building includes connecting end piles 10 and modular connecting plates 20. Each set of modular connecting plates 20 has a detachable base 30 installed at its bottom. Support legs 11 are coaxially connected to the bottom of the connecting end piles 10. Several uniformly spaced, vertically arranged first insertion posts 13 are symmetrically installed on the outer walls of both sides of the connecting end piles 10. Each set of first insertion posts 13 has a first fixing screw hole 14 on its outer wall. Several uniformly spaced, vertically arranged second insertion posts 21 are installed on one side of the modular connecting plate 20. A connecting socket 22, matching the size and position of the second insertion posts 21, is opened on the side of the modular connecting plate 20 away from the second insertion posts 21. A second fixing screw hole 24 is opened on the outer wall of the second insertion posts 21. The modular connecting plate 20 is connected to the connecting end pile 10 and to each adjacent modular connecting plate 20 by the first fixing bolt 40. The connecting end pile 10, modular connecting plate 20 and detachable base 30 make the installation of modular prefabricated buildings more convenient. The support foot 11 at the bottom of the connecting end pile 10 can enhance stability. The first plug post 13 and the first fixing screw hole 14 on the outer walls of both sides facilitate connection with the modular connecting plate 20. The second plug post 21, connecting socket 22 and the second fixing screw hole 24 on the modular connecting plate 20 facilitate the splicing between modules. The modular connecting plate 20 is connected to the connecting end pile 10 and adjacent modular connecting plates 20 by the first fixing bolt 40, which enhances the stability of the overall structure.

[0030] Furthermore, several sets of ground bolts 12 are installed on the support foot 11 for fixing to the ground, so that the connecting end pile 10 can be firmly fixed to the ground, enhancing the stability of the entire device and preventing displacement or tilting caused by external forces.

[0031] Specifically, the outer wall of the modular connecting plate 20 is provided with a first through hole 23 for installing the first fixing bolt 40, which makes the connection between the modular connecting plate 20 and the connecting end pile 10 more firm and reliable, and also facilitates installation and disassembly, thereby improving construction efficiency.

[0032] It is worth noting that the top surface of the detachable base 30 is equipped with a third insertion post 31 that is inserted into the bottom of the modular connecting plate 20. The outer wall of the third insertion post 31 is provided with a third fixing screw hole 32. The detachable base 30 is connected to the bottom of the modular connecting plate 20 by the second fixing bolt 50, which not only enhances the connection strength between the modular connecting plate 20 and the detachable base 30, but also makes the entire device more flexible and convenient to disassemble and reassemble.

[0033] The modular connecting plate 20 also has a second through hole 25 on its outer wall for installing the second fixing bolt 50, ensuring a stable connection between the detachable base 30 and the modular connecting plate 20.

[0034] In addition, the detachable base 30 adjacent to the connecting end pile 10 fits tightly against the side of the support foot 11, which not only enhances the structural integrity of the entire device, but also improves its ability to resist crosswinds, earthquakes and other natural disasters, so that the prefabricated building can remain safe and stable under extreme weather conditions.

[0035] The working principle of this modular prefabricated building quick connection device:

[0036] Place the connecting end pile 10 in the predetermined position using the support foot 11, and secure the support foot 11 to the ground using the ground bolt 12. Next, select the modular connecting plate 20, align the second insertion post 21 on one side of it with the corresponding first insertion post 13 on the connecting end pile 10, and make the two tightly inserted.

[0037] Then, insert the first fixing bolt 40 through the first through hole 23 and screw it into the first fixing screw hole 14 and the second fixing screw hole 25 to stably connect the modular connecting plate 20 to the connecting end pile 10. If it is necessary to install the detachable base 30, insert the third plug post 31 on the top surface of the detachable base 30 into the corresponding position on the bottom of the modular connecting plate 20, insert the second fixing bolt 50 through the second through hole 25 and screw it into the third fixing screw hole 32 to complete the connection between the detachable base 30 and the modular connecting plate 20. The end of the detachable base 30 adjacent to the connecting end pile 10 should be tightly fitted to the side of the support foot 11.

[0038] If you want to add more modular connecting plates 20 in the future, simply insert the second plug post 21 of the new modular connecting plate 20 into the connecting socket 22 of the installed modular connecting plate 20, and then fix it with the first fixing bolt 40. By repeating this operation, the modular prefabricated building can be built efficiently.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
