Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a rapid assembly node for prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings characterized by standardized design, factory production, assembly construction, integrated decoration, and information management. Some or all of the building components are prefabricated in a factory, transported to the construction site, and assembled using reliable connection methods.

[0003] In traditional prefabricated construction, workers assemble modular building components by quickly splicing nodes to obtain a complete building. However, in actual installation, traditional quick-connect splicing nodes are mostly designed with fixed dimensions, and their fixed structure specifications are relatively simple, making it difficult to adapt to quadrilateral building columns with different cross-sectional sizes. When encountering situations where there are deviations in the cross-sectional dimensions of the columns or different column specifications in different projects, it is necessary to perform secondary processing such as cutting and grinding on-site, which not only increases the construction process and labor costs but also reduces construction efficiency. Alternatively, if the splicing node is not tightly fitted to the column, the stability after splicing is insufficient, and the load-bearing capacity of the node cannot be guaranteed, posing certain safety hazards and seriously affecting subsequent use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rapid assembly node for prefabricated buildings. This solves the problem that traditional rapid assembly nodes are mostly designed with fixed dimensions, resulting in relatively limited specifications for their fixed structures. This makes them difficult to adapt to quadrilateral building columns with different cross-sectional sizes. When encountering deviations in column cross-sectional dimensions or different column specifications in different projects, either on-site cutting and grinding of the assembly node are required, increasing construction procedures and labor costs while reducing construction efficiency, or the assembly node is not tightly fitted to the column, leading to insufficient stability after assembly, failing to guarantee the node's load-bearing capacity, posing certain safety hazards, and seriously affecting subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid assembly node for prefabricated buildings, comprising two building columns, each with a connecting seat attached to its outer wall, and an adjustment mechanism on its outer wall. The adjustment mechanism includes a fixing plate, a first adjusting plate, a fixing block, and a first bolt. Multiple fixing plates are provided, each fixedly connected to the outer wall of the connecting seat on both sides. A first adjusting plate is attached to the side of the outer wall of the fixing plate on both sides that is far apart from the fixing plate on both sides. A fixing block is attached to the side of the outer wall of the first adjusting plate on both sides that is far apart from the fixing plate on both sides. A first bolt is threadedly connected to the inner wall of each fixing block on both sides. The outer wall of the first bolt on both sides penetrates the outer walls of the first adjusting plate and the fixing plate on both sides, extending to the side of the outer wall of the fixing plate on both sides that is close to each other.

[0006] Preferably, an extension mechanism is provided between the two fixing plates; the extension mechanism includes threaded holes, a second adjusting plate, and a second bolt; multiple threaded holes are provided, which are respectively opened on the outer wall of the connecting seats on both sides, and a second adjusting plate is provided on the side of each threaded hole on both sides. A second bolt is inserted into the inner wall of each of the multiple second adjusting plates, and the outer wall of each of the multiple second bolts is threaded to the inner wall of the threaded holes on both sides. The ends of the multiple second bolts are respectively pressed against the outer wall of the two building columns.

[0007] Preferably, a limiting block is fixedly connected to the outer wall of the two fixed blocks on the same side that are close to each other, and the outer wall of the two limiting blocks is inserted into the inner wall of the first adjusting plate.

[0008] Preferably, the side wall of the connecting seat is provided with a positioning groove, and a positioning strip is machined on the side of the outer wall of the connecting seat away from the positioning groove.

[0009] Preferably, an anti-slip seat is fixedly connected to the inner wall of the connecting seat, and the outer wall of the anti-slip seat away from the connecting seat is attached to the outer wall of the building column. Beneficial effects

[0010] This utility model provides a quick-assembly node for prefabricated buildings. It has the following advantages: This quick-assembly node, through the cooperation of a fixing plate, a first adjusting plate, a fixing block, and a first bolt, allows for adjustment of the fixing structure of the splicing node according to the cross-sectional size of the actual quadrilateral building column, thereby adapting to quadrilateral building columns of different sizes. This not only ensures the stability and load-bearing capacity of the splicing node but also improves the compatibility between the quick-assembly node and the column.

[0011] By using threaded holes, a second adjusting plate, and a second bolt, the splicing node can compensate for dimensional deviations in building components during processing and assembly. This not only ensures the flatness and firmness of the overall structure but also significantly improves the flexibility and adaptability of the rapid splicing node. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In actual installation, traditional quick-connect joints are mostly designed with fixed dimensions, and their fixed structure specifications are relatively simple, making it difficult to adapt to quadrilateral building columns with different cross-sectional sizes. When there are deviations in the cross-sectional dimensions of the columns or different column specifications in different projects, it is necessary to perform secondary processing such as cutting and grinding on-site, which not only increases the construction process and labor costs but also reduces construction efficiency. Alternatively, if the splicing joint is not tightly fitted to the column, the stability after splicing is insufficient, and the load-bearing capacity of the joint cannot be guaranteed, posing certain safety hazards and seriously affecting subsequent use.

[0016] In view of this, the present invention provides a quick-assembly node for prefabricated buildings. This quick-assembly node for prefabricated buildings, through the cooperation of a fixing plate, a first adjusting plate, a fixing block and a first bolt, realizes the adjustment of the fixing structure of the splicing node according to the cross-sectional size of the actual quadrilateral building column, thereby adapting to quadrilateral building columns of different sizes. This not only ensures the stability and load-bearing capacity of the splicing node, but also improves the compatibility between the quick-assembly node and the column.

[0017] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0018] Example 1, by Figure 1-4 It is known that a prefabricated building quick-assembly node includes building columns 1, two building columns 1 are provided, and the outer walls of the two building columns 1 are attached to connecting seats 2. The outer walls of the connecting seats 2 are provided with adjustment mechanisms. The adjustment mechanism includes fixing plates 3, first adjusting plates 4, fixing blocks 5 and first bolts 6. Multiple fixing plates 3 are provided, and multiple fixing plates 3 are respectively fixedly connected to the outer walls of the two connecting seats 2. The outer walls of the two fixing plates 3 that are far apart are attached to the first adjusting plates 4. The outer walls of the two first adjusting plates 4 that are far away from the two fixing plates 3 are attached to the fixing blocks 5. The inner walls of the two fixing blocks 5 are threadedly connected to the first bolts 6. The outer walls of the two first bolts 6 penetrate the outer walls of the two first adjusting plates 4 and the fixing plates 3 respectively, and extend to the outer walls of the two fixing plates 3 that are close to each other. In the specific implementation process, it is worth noting that the building column 1 is a square column, and the specific number can be set according to the actual construction needs. For example, there can be two, set vertically, and the two building columns 1 need to be connected together through quick splicing nodes. There are eight connecting seats 2, with four connecting seats 2 corresponding to each of the two building columns 1. The material of the connecting seat 2 can be Q355B low alloy high strength structural steel, and its cross section is 'L' shaped. The four connecting seats 2 are connected end to end to form a quadrilateral. The number and material of the fixing plate 3 are the same as those of the connecting seat 2. Its overall structure is an 'L' shaped plate structure. It is fixed to the outer wall of the connecting seat 2. Circular through holes are opened on both sides of its top. There are a total of eight first adjusting plates 4, with four first adjusting plates 4 corresponding to one building column 1. The material of the first adjusting plate 4 is the same as that of the connecting seat 2. Its overall structure is a strip plate, and its top is processed with strip-shaped through grooves with semi-circular sides. The material and number of the fixing block 5 are the same as those of the connecting seat 2. Its overall structure is a square plate. The first bolt 6 is a standard 8.Grade 8 high-strength carbon steel bolts, the same number as fixing blocks 5, are used in actual work. When connecting two building columns 1, workers take two sets of connecting seats 2 (four in a set) according to the two building columns 1. First, the upper and lower sets of corresponding connecting seats 2 are fixed together by the extension mechanism to form a fixing component, thus obtaining four fixing components. Then, two fixing components are taken and attached to the two outer corners of the two building columns 1 in a vertical state. The gap between the two building columns 1 should be less than the height of the fixing component formed by the upper and lower connecting seats 2. Then, a first adjusting plate 4 is taken and placed on top of the two fixing components. The bottom sides of the first adjusting plate 4 are respectively attached to the tops of the two fixing components, forming a bridge-like structure. Next, two first bolts 6 are passed through the circular through holes opened on the fixing plates 3 on the two fixing components and the inner wall of the first adjusting plate 4. Finally, two fixing blocks 5 are respectively threaded to the outer walls of the two first bolts 6. As the first bolts 6 rotate, their cooperation with the fixing blocks 5 can fix the two sets of fixing components together through the first adjusting plate 4. Similarly, the bottoms of the two sets of fixing components are also fixed together through the first adjusting plate 4. The first adjusting plate 4, fixing block 5, and first bolt 6 are connected together. At this time, the two sets of fixing components form a 'C' shape structure, which is firmly fixed to the outer wall of the two building columns 1. Similarly, the remaining connecting seats 2, fixing plates 3, first adjusting plates 4, fixing blocks 5, and first bolts 6 are connected in the same way. Finally, a square tubular splicing node is obtained. This splicing node can firmly connect the two building columns 1 together. When it is necessary to adjust the splicing range of the quick splicing node according to the cross-sectional size of the building column 1, the worker can rotate the first adjusting plate 4, fixing block 5, and first bolt 6 counterclockwise. A bolt 6 is used to create a gap between the fixing block 5 and the first adjusting plate 4. This gap allows the fixing block 5 and the first bolt 6 to slide along the inner wall of the first adjusting plate 4. After determining the distance between the two fixing plates 3, the two fixing blocks 5 are pushed to the designated position, and the fixing plates 3, the first adjusting plate 4, and the fixing blocks 5 are then re-fixed together using the first bolt 6. This ensures that the prefabricated building quick-assembly node can adapt to various quadrilateral building columns 1, guaranteeing connection stability while improving the compatibility between the prefabricated building quick-assembly node and the building columns 1. Furthermore, an extension mechanism is provided between the two fixing plates 3; the extension mechanism includes a threaded hole 7, a second adjusting plate 8, and a second bolt 9; multiple threaded holes 7 are provided, which are respectively opened on the outer wall of the two connecting seats 2, and the sides of the threaded holes 7 on both sides are provided with second adjusting plates 8, and the inner walls of the multiple second adjusting plates 8 are each inserted with a second bolt 9, the outer walls of the multiple second bolts 9 are respectively threaded to the inner walls of the threaded holes 7 on both sides, and the ends of the multiple second bolts 9 are respectively pressed against the outer walls of the two building columns 1; In the specific implementation process, it is worth noting that there are threaded holes 7 on both sides of the outer wall of one connecting seat 2, and eight second adjusting plates 8 are provided. The second adjusting plate 8 is a vertical strip-shaped structure, made of the same material as the connecting seat 2, and its overall shape is the same as the first adjusting plate 4, but its overall size is larger than the first adjusting plate 4. The number of second bolts 9 is the same as the number of threaded holes 7, and their material is the same as the first bolts 6, allowing them to match the threaded holes 7. In actual work, when the distance between the two building columns 1 is found to be large, workers can adjust the upper and lower connecting seats 2 before assembling the fixing components. The distance between them can be adjusted by rotating the second bolt 9 counterclockwise. The second bolt 9 gradually moves away from the inner wall of the threaded hole 7. At this time, the clamping force of the second adjusting plate 8 disappears, thereby pulling a connecting seat 2 to adjust the height of the entire prefabricated building quick splicing node. After reaching the designated position, the worker rotates the second bolt 9 clockwise to make it clamp the second adjusting plate 8 and the outer wall of the building column 1 again. In actual use, this prefabricated building quick splicing node can also be used between two building horizontal columns. The operation is the same. Therefore, it can be flexibly applied according to the actual construction situation. Furthermore, limit blocks 10 are fixedly connected to the outer walls of the two fixed blocks 5 on the same side that are close to each other, and the outer walls of the two limit blocks 10 are inserted into the inner wall of a first adjusting plate 4. In the specific implementation process, it is worth noting that the material and quantity of the limiting block 10 are the same as those of the fixing block 5. Its overall shape is 'T', and its bottom can be movably connected with the through groove opened on the top of the first adjusting plate 4 to limit the fixing block 5 and prevent it from rotating with the first bolt 6. This not only improves the ease of installation, but also ensures the stability of the final quick splicing node. Example 2, by Figure 1-4 It can be seen that the side wall of the connecting seat 2 is provided with a positioning groove 11, and the outer wall of the connecting seat 2 away from the positioning groove 11 is provided with a positioning strip 12. In the specific implementation process, it is worth noting that the positioning groove 11 is a rectangular groove, and the positioning strip 12 has the same shape as the positioning groove 11. The two can fit tightly together. The positioning groove 11 and the positioning strip 12 are respectively processed on both sides of the connecting seat 2. In the actual installation process, when the cross-sectional area of ​​the building column 1 is the same as the area of ​​the quadrilateral formed by the four connecting seats 2, the four connecting seats 2 can fit tightly together through the positioning groove 11 and the positioning strip 12 on their respective sides, which improves the connection stability and installation convenience between the two connecting seats 2 on the same side. Furthermore, an anti-slip seat 13 is fixedly connected to the inner wall of the connecting seat 2, and the outer wall of the anti-slip seat 13, away from the connecting seat 2, is attached to the outer wall of the building column 1. In the specific implementation process, it is worth noting that the corner of the inner wall of the connecting seat 2 is processed with a groove with an 'L' shape. The inner wall of the groove is fixed with an anti-slip seat 13. The anti-slip seat 13 can be made of rubber-modified polyurethane composite material. Its outer wall is directly attached to the corner of the outer wall of the building column 1, which can compensate for the slight unevenness of the corner surface of the building column 1 and achieve a tight fit, thereby improving the connection stability between the prefabricated building quick splicing node and the building column 1. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
