Description

Technical Field

[0001] This invention relates to the field of frame beam and column technology, and more specifically, to a prestressed concrete frame beam and column structure. Background Technology

[0002] In the field of modern construction engineering, prestressed concrete structures are widely used in various large-scale building structures, especially frame beam-column structures, due to their significant advantages such as high strength, good crack resistance, and high durability. As the main load-bearing system of a building, the stability and reliability of the frame beam-column structure are directly related to the safety and service life of the entire building. Compared with traditional cast-in-place reinforced concrete and masonry buildings, prefabricated assembled buildings are constructed by prefabricating building components such as beams, slabs, columns, and exterior walls in a factory, which are then cured, inspected, and transported to the site for installation. Concrete frame beam-column structures are an important component of prefabricated assembled buildings.

[0003] Currently, traditional prestressed concrete frame beam-column structures mostly use welding or ordinary bolt connections. While welding can achieve relatively strong connections, it is prone to generating welding stress during the welding process, leading to micro-cracks within the structure and affecting its overall performance and durability. Moreover, welding operations have high requirements for the construction environment and are difficult to perform in some special environments (such as humid environments or environments with flammable and explosive gases). Furthermore, if connection problems occur after welding, disassembly and repair are difficult. Although ordinary bolt connections are relatively convenient to install and disassemble, they are prone to loosening under long-term use due to external forces and vibrations, resulting in unstable connections and affecting the load-bearing capacity and safety of the entire frame beam-column structure. Therefore, we propose a prestressed concrete frame beam-column structure. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a prestressed concrete frame beam-column structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prestressed concrete frame beam-column structure, comprising a beam-column body, with crossbeams installed on both sides of the beam-column body, cross mounting plates installed on both sides of the beam-column body and the crossbeams, and several sets of right-angle mounting brackets installed between the beam-column body and the crossbeams. A soft metal pad is provided on one side of the cross mounting plate and the right-angle mounting bracket, a triangular plate is installed on the outside of the right-angle mounting bracket, and several sets of connecting components are provided on the outside of the cross mounting plate and the right-angle mounting bracket. Several sets of through holes are opened inside the cross mounting plate, the right-angle mounting bracket and the soft metal pad, and several sets of threaded holes are opened inside the beam-column body and the crossbeams. The connecting components include mounting cylinders installed on the outside of the cross mounting plate and the right-angle mounting bracket. A connecting rod is connected inside the mounting cylinder. A fixing plate is installed at one end of the connecting rod, and a bolt is installed at the other end of the connecting rod. A butterfly handle is installed on one side of the fixing plate, and a working groove is opened on one side of the butterfly handle. A sealing ring is installed inside the mounting cylinder.

[0006] Preferably, both the cross-shaped mounting plate and the right-angle mounting bracket are connected to the beam column and the crossbeam respectively through several sets of connecting components.

[0007] Preferably, the through hole and the threaded hole correspond to each other, and the mounting sleeve corresponds to the through hole.

[0008] Preferably, a positioning plate is installed on the outer side of the fixing plate, a magnet is embedded in one side of the positioning plate, and a groove and a positioning slot are respectively opened on one side of the mounting cylinder.

[0009] Preferably, the connecting rod is located inside the sealing ring, and a magnet is embedded inside the mounting cylinder on one side of the positioning groove.

[0010] Preferably, the positioning plate is adapted to the positioning groove, and magnet one and magnet two attract each other.

[0011] Preferably, the sealing ring is made of rubber, the inner diameter of the sealing ring is adapted to the diameter of the connecting rod, and the outer diameter of the sealing ring is adapted to the inner diameter of the mounting cylinder.

[0012] Preferably, the bolt is adapted to the threaded hole and the bolt is adapted to the interior of the mounting cylinder.

[0013] The technical effects and advantages of this invention are as follows: In use, this invention utilizes a positioning plate and positioning groove in the connecting assembly, along with the magnetic attraction of magnet one and magnet two. After the bolt is screwed into the threaded hole, the positioning plate accurately embeds into the positioning groove, and magnet one and magnet two attract each other, effectively preventing the butterfly handle from rotating during subsequent operations. This ensures the tightness of the bolt connection, greatly enhances the connection stability between the cross mounting plate, right-angle mounting bracket, and beams / columns, improves the load-bearing capacity and safety of the entire prestressed concrete frame beam-column structure, effectively resists various external forces and vibrations, and extends the service life of the structure.

[0014] In use, this invention features a butterfly handle design, allowing users to hold the handle or use tools inserted into the working slot for rotation, enabling the bolts to be screwed in and out without the need for complex tools and cumbersome procedures. This greatly simplifies the installation and disassembly process and improves work efficiency. Furthermore, the mounting cylinder design not only provides installation space for the connecting rod and bolts but also stores the bolts inside during disassembly, preventing loss and facilitating subsequent reinstallation. This reduces construction costs and brings great convenience to workers. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] As attached Figures 1-6The prestressed concrete frame beam-column structure shown includes a beam-column body 1, with crossbeams 2 installed on both sides of the beam-column body 1, and cross mounting plates 3 installed on both sides of the beam-column body 1 and the crossbeams 2. Several sets of right-angle mounting brackets 4 are installed between the beam-column body 1 and the crossbeams 2. Soft metal pads 5 are provided on one side of the cross mounting plates 3 and the right-angle mounting brackets 4. Triangular plates 6 are installed on the outside of the right-angle mounting brackets 4. Several sets of connecting components 7 are provided on the outside of the cross mounting plates 3 and the right-angle mounting brackets 4. The cross mounting plates 3 and the right-angle mounting brackets 4 are connected to the beam-column body 1 and the crossbeams 2 respectively through several sets of connecting components 7. Several sets of through holes 8 are opened inside the cross mounting plates 3, the right-angle mounting brackets 4 and the soft metal pads 5. Several sets of threaded holes 9 are opened inside the beam-column body 1 and the crossbeams 2. The through holes 8 and the threaded holes 9 correspond to each other. The connecting assembly 7 includes mounting cylinders 71 installed on the outside of the cross mounting plate 3 and the right-angle mounting bracket 4, respectively. The mounting cylinders 71 correspond to the through holes 8. A connecting rod 72 is connected inside the mounting cylinder 71. A fixing plate 73 is installed at one end of the connecting rod 72, and a bolt 74 is installed at the other end of the connecting rod 72. The bolt 74 is adapted to the threaded hole 9 and the interior of the mounting cylinder 71. A butterfly handle 77 is installed on one side of the fixing plate 73, and a working groove 78 is formed on one side of the butterfly handle 77. A sealing ring 79 is installed inside the mounting cylinder 71. The outer surface of the fixing plate 73... A positioning plate 75 is installed on the side, and a magnet 76 is embedded in one side of the positioning plate 75. A groove 710 and a positioning groove 711 are respectively opened on one side of the mounting cylinder 71. The connecting rod 72 is located inside the sealing ring 79. A magnet 712 is embedded inside the mounting cylinder 71 and on one side of the positioning groove 711. The positioning plate 75 is adapted to the positioning groove 711. The magnet 76 and the magnet 712 are attracted to each other. The sealing ring 79 is made of rubber. The inner diameter of the sealing ring 79 is adapted to the diameter of the connecting rod 72. The outer diameter of the sealing ring 79 is adapted to the inner diameter of the mounting cylinder 71.

[0024] The sealing ring 79 is made of rubber, and its inner diameter is matched with the diameter of the connecting rod 72, and its outer diameter is matched with the inner diameter of the mounting cylinder 71. This ensures the sealing of the connection and prevents external impurities from entering and affecting the connection performance. Using several sets of connecting components 7, the cross mounting plate 3 and the right-angle mounting bracket 4 are connected to the beam column 1 and the crossbeam 2 to complete the installation and fixation of the entire prestressed concrete frame beam column structure. The triangular plate 6 installed on the outside of the right-angle mounting bracket 4 can further enhance the stability of the structure. When magnet 76 and magnet 712 attract each other, it can be determined that the device is installed. The magnetic attraction enhances the fixing effect.

[0025] The working principle of this invention is as follows: When installing a prestressed concrete frame beam-column structure, the cross mounting plate 3 and the right-angle mounting bracket 4 are first placed at the corresponding positions of the beam-column 1 and the cross beam 2, respectively. At this time, the soft metal pad 5 set on one side of the cross mounting plate 3 and the right-angle mounting bracket 4 is in contact with the beam-column 1 and the cross beam 2. The soft metal pad 5 is welded to the inner side of the right-angle mounting bracket 4, which plays a role in buffering and increasing the connection stability. At the same time, it is ensured that the several sets of through holes 8 opened inside the cross mounting plate 3, the right-angle mounting bracket 4 and the soft metal pad 5 correspond to the several sets of threaded holes 9 opened inside the beam-column 1 and the cross beam 2. When the cross mounting plate 3 and the right-angle mounting bracket 4 need to be installed with the beam column 1 and the crossbeam 2 respectively, after several sets of bolts 74 are aligned with several sets of through holes 8 and threaded holes 9, the user holds the butterfly handle 77 or uses a tool to rotate it in the working groove 78, and pushes the connecting rod 72 to move until the bolts 74 are screwed into the threaded holes 9. When the bolts 74 are gradually connected in the threaded holes 9, in order to confirm the tightening state, the positioning plate 75 is located in the positioning groove 711 until the magnet 1 76 and the magnet 2 712 attract each other, then the device installation is confirmed to be complete. The magnetic attraction increases the fixing effect and prevents the butterfly handle 77 from rotating in subsequent operations. In addition, the mounting cylinder 71 can also prevent the bolts 74 from being lost. When it is necessary to disassemble the cross mounting plate 3 and the right-angle mounting bracket 4 from the beam column 1 and the crossbeam 2 respectively, the user holds the butterfly handle 77 or uses a tool to rotate it in the opposite direction in the working groove 78 until the bolt 74 is disengaged from the threaded hole 9. When the bolt 74 moves into the mounting cylinder 71, the magnet 1 76 and the magnet 2 712 disengage, and the positioning plate 75 gradually moves outward from the positioning groove 711. This is the disassembly work. The operation of several sets of connecting components 7 is carried out in the previous step, which facilitates quick installation or disassembly, brings convenience to the staff, and prevents the loss of bolts 74.
