Technical Field

[0001] The utility model relates to the technical field of assembled structures, in particular to a connection node of a prefabricated assembled structure. Background Art

[0002] Prefabricated structure, short for prefabricated concrete structure, is a concrete structure constructed by assembling and connecting prefabricated components as the primary load-bearing members. Prefabricated reinforced concrete structure is a key development direction for building structures in my country. It is conducive to the development of my country's building industrialization, improving production efficiency and energy conservation, developing green and environmentally friendly buildings, and improving and ensuring the quality of construction projects. Compared with cast-in-place construction methods, prefabricated PC structures are conducive to green construction because they better meet the green construction requirements of land conservation, energy conservation, material conservation, water conservation, and environmental protection. They also reduce negative impacts on the environment, including reducing noise, preventing dust, reducing environmental pollution, clean transportation, minimizing site disturbances, and conserving resources and energy such as water, electricity, and materials, adhering to the principles of sustainable development.

[0003] When assembling steel bars, a connecting seat is installed between the upper and lower steel bars, especially for the steel bars on the fixed side. The connecting seat and the upper and lower steel bars are fixed by a flange, and then the side steel bars are fixed to the connecting seat through connecting parts such as splints, so as to realize the assembly of the side steel bars. However, this connection method has very high requirements on the supporting strength of the connecting seat. For this reason, a reinforcing plate is installed on the side of the connecting seat to improve the supporting strength of the connecting seat. However, the setting of the reinforcing plate has hindered the installation of the side steel bars, and special manufacturing requirements are required for the production of the connecting seat for the installation of the side steel bars, which greatly reduces the adaptability of the connecting seat.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figures 1-4 A connection node of a prefabricated structure includes a column base 1, a first connection plate 3 is installed along the upper and lower edges of the column base 1, and a plurality of first U-shaped grooves 5 are arranged at intervals along the edge of the first connection plate 3, and the first U-shaped grooves 5 pass through the side of the first connection plate 3;

[0024] Reinforcement columns 2 are provided at the upper and lower ends of the column base 1, and a second connecting plate 4 is installed along the edge of one end of the reinforcement column 2 close to the column base 1. The second connecting plate 4 is fixed corresponding to the first connecting plate 3, and the connecting plates are fixed by bolts, so that the column base 1 is used as a connecting node to connect the reinforcement column 2. In actual use, reinforcing ribs are installed on the inner and outer surfaces of the inner wall of the column base 1 and the inner wall of the reinforcement column 2 to increase the rigidity of the column base 1 and the reinforcement column 2.

[0025] like Figure 1 and Figure 4As shown, a plurality of second U-shaped grooves 6 are provided along the edge of the second connecting plate 4, and the second U-shaped grooves 6 pass through the side of the second connecting plate 4, and the second U-shaped grooves 6 correspond to the first U-shaped grooves 5; a plurality of reinforcing rods 7 with threads on the surface are provided on the side of the column base 1, and the ends of the reinforcing rods 7 are respectively placed in the corresponding second U-shaped grooves 6, and at least two locking nuts 8 are respectively threadedly connected to the ends of the reinforcing rods 7, and the locking nuts 8 correspond to the first connecting plate 3 and the second connecting plate 4 respectively. When in use, take the reinforcing rod 7, first install the locking nuts 8 on the ends of the reinforcing rod 7, and make the distance between the upper and lower locking nuts 8 less than the height of the column base 1. Then place the ends of the reinforcing rod 7 in the U-shaped grooves at the upper and lower ends of the column base 1 respectively, and screw the locking nut 8 on the end of the reinforcing rod 7 to make it rest on the first connecting plate 3, then take a new locking nut 8 and install it on the end of the reinforcing rod 7 again, and press the locking nut 8 against the second connecting plate 4, so as to fix the reinforcing rod 7 on the side of the column base 1 to increase the supporting strength of the column base 1. When steel bars need to be installed on the side of the column base 1, the reinforcing rod 7 at the steel bar installation position can be directly removed by screwing the locking nut 8, or the installation of the reinforcing rod 7 on this side can be omitted when installing the reinforcing rod 7, thereby improving the adaptability of the connection node when used.

[0026] Furthermore, in order to improve the locking strength of the locking nut 8 on the connecting plate, as Figure 4 As shown, a washer 16 is sleeved on the end of the reinforcing rod 7, and the washer 16 is placed between the locking nut 8 and the connecting plate.

[0027] It should be noted that if Figure 1 and Figure 3 As shown, a first connecting plate 10 is provided on the side of the second connecting plate 4 away from the first connecting plate 3. The first connecting plate 10 is fixed to the second connecting plate 4 through the mounting plate 9. A support beam 11 is provided between the two first connecting plates 10. A second connecting plate 15 is installed at one end of the support beam 11 close to the first connecting plate 10. The second connecting plate 15 corresponds to the first connecting plate 10 and the two are fixedly connected. In actual use, the connecting plates are fastened by bolts, and reinforcing ribs are installed on the inner and outer surfaces of the first connecting plate 10 and the second connecting plate 15.

[0028] Among them, the support beam 11 is an "I" shape with a hollow middle part, and cross-angled reinforcement beams 12 are installed on both sides of the middle part of the support beam 11, which not only ensures the supporting strength of the support beam 11, but also reduces the weight of the support beam 11 and the production consumption during production.

[0029] A second limiting plate 17 is installed at one end of the support beam 11 close to the column base 1, and a first limiting plate 13 corresponding to the second limiting plate 17 is installed on the column base 1, and a fixing plate 14 is provided on both sides of the first limiting plate 13. The two ends of the fixing plate 14 are respectively fixed on the first limiting plate 13 and the second limiting plate 17. The connection between the two limiting plates is fixed by the fixing plate 14 to strengthen the connection and fixing effect of the support beam 11 through the connecting plate.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
