Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically to a beam-column connection node structure for prefabricated buildings. Background Technology

[0002] The beam-column connection structure in prefabricated buildings is a key structural component used to connect beams and columns. It combines prefabricated beam components with prefabricated or cast-in-place column components according to design requirements to form a stable connection, thereby jointly bearing the load of the building structure.

[0003] A search revealed a beam-column connection node structure for prefabricated buildings, comprising a main beam support, with a main beam embedded part fixedly welded to the bottom of the main beam support, a lower baffle and an upper baffle fixedly welded to the outer surface of the main beam support, a side plate fixedly welded to the surface of the main beam support between the lower baffle and the upper baffle, a fixing plate attached to the surface of the side plate, insert plates fixedly welded to the top and bottom of the fixing plate, both insert plates having through holes on their surfaces, a crossbeam embedded part fixedly welded to the surface of the insert plate away from the main beam support, and two positioning components installed inside the fixing plate.

[0004] The implementation of this technical solution has at least the following drawbacks: Although this utility model can connect beams and columns to horizontal beams, it requires many bolts for positioning and connection, and cannot provide sufficient load-bearing capacity in case of bolt breakage, thus affecting the overall stability of the prefabricated building, which urgently needs improvement. Therefore, we propose a beam-column connection node structure for prefabricated buildings. Utility Model Content

[0005] The purpose of this utility model is to provide a beam-column connection node structure for prefabricated buildings, which solves the problem mentioned in the background technology that requires a lot of bolts for positioning and connection, and cannot bear certain loads when the bolts break, thus affecting the overall stability of the prefabricated building.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a beam-column connection node structure for prefabricated buildings, including a lower beam column, an upper beam column at the upper end of the lower beam column, a column base between the lower beam column and the upper beam column, a crossbeam on one side of the column base, insert plates welded to both the front and rear sides of the crossbeam, a first limiting plate welded to the side of the column base near the insert plate, a slot in the middle of the first limiting plate, a positioning frame on the outer side of the crossbeam, and limiting grooves at both the upper and lower ends of the positioning frame.

[0007] By adopting the above technical solution, the position of the beam can be defined, and then the positioning frame can be pushed to the left until the second limiting plate abuts against the outside of the insert plate, thereby defining the insertion position of the insert plate. Then, the positioning frame and the connecting plate are connected and defined by bolts passing through the positioning groove, thus achieving the effect of beam connection and installation. Moreover, the mortise and tenon joint reduces the amount of bolts required. In the event of bolt breakage, the positioning frame can provide a certain load-bearing capacity to the beam and connecting plate after sliding to the outside of the beam and connecting plate, thus ensuring the stability of the prefabricated building. After the beam is inserted and installed in place, the limiting groove on the positioning frame can define the position of the column base and the connecting plate, thereby facilitating the installation and connection between the lower beam column, the upper beam column and the column base, further improving the connection efficiency of beams and columns.

[0008] Optionally, a connecting plate is welded to the upper end of the lower beam column and the lower end of the upper beam column, and the connecting plate is fixedly connected to the column base by bolts.

[0009] By adopting the above technical solution and setting the connecting plate, it is convenient to connect the lower beam column, the upper beam column and the column base.

[0010] Optionally, the size of the insert plate is adapted to the size of the slot, and the insert plate and the slot are movably connected.

[0011] By adopting the above technical solution, the installation position of the crossbeam can be defined through the cooperation of the insert plate and the slot.

[0012] Optionally, positioning grooves are provided at both the upper and lower ends of the positioning frame and the connecting plate.

[0013] By adopting the above technical solution and setting the positioning groove, it is convenient to limit the installation of the positioning frame.

[0014] Optionally, the size of the positioning frame is adapted to the size of the crossbeam, and the positioning frame is movably connected to the crossbeam.

[0015] By adopting the above technical solution, the positioning frame can be moved left and right on the outside of the crossbeam.

[0016] Optionally, a second limiting plate is welded to the inner side of the positioning frame, and the second limiting plate is symmetrically arranged.

[0017] By adopting the above technical solution and setting the second limiting plate, the position of the insertion plate can be limited.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] This technical solution, through the design of a lower beam column, upper beam column, column base, crossbeam, positioning frame, and limiting groove, can limit the position of the crossbeam. Then, the positioning frame is pushed to the left until the second limiting plate abuts against the outside of the insert plate, thus limiting the insertion position of the insert plate. Bolts passing through the positioning groove connect and limit the positioning frame and the connecting plate, achieving the effect of connecting and installing the crossbeam. Furthermore, the mortise and tenon joint reduces the amount of bolts required. Even if a bolt breaks, the positioning frame, after sliding to the outside of the crossbeam and connecting plate, can provide some load-bearing capacity, ensuring the stability of the prefabricated building. After the crossbeam is inserted and installed, the limiting groove on the positioning frame limits the position of the column base and connecting plate, facilitating the installation and connection between the lower beam column, upper beam column, and column base, further improving the connection efficiency of the beam and column.

[0026] Please see Figure 1-4This utility model provides a technical solution: a beam-column connection node structure for prefabricated buildings, including a lower beam-column 1, an upper beam-column 11 at the upper end of the lower beam-column 1, a column base 12 between the lower beam-column 1 and the upper beam-column 11, a crossbeam 2 on one side of the column base 12, insert plates 21 welded to both the front and rear sides of the crossbeam 2, a first limiting plate 22 welded to the side of the column base 12 near the insert plate 21, a slot 23 opened in the middle of the first limiting plate 22, a positioning frame 3 on the outer side of the crossbeam 2, and the upper and lower sides of the positioning frame 3... Each end is provided with a limiting groove 6. The upper and lower ends of the positioning frame 3 and the connecting plate 13 are provided with positioning grooves 4. The positioning grooves 4 are provided to facilitate the installation and limitation of the positioning frame 3. The size of the positioning frame 3 is adapted to the size of the crossbeam 2, and the positioning frame 3 is movably connected to the crossbeam 2, which facilitates the left and right movement of the positioning frame 3 on the outside of the crossbeam 2. A second limiting plate 5 is welded to the inner side of the positioning frame 3, and the second limiting plates 5 are symmetrically arranged. The position of the insert plate 21 can be limited by the setting of the second limiting plates 5.

[0027] A connecting plate 13 is welded to the upper end of the lower beam column 1 and the lower end of the upper beam column 11. The connecting plate 13 is fixedly connected to the column base 12 by bolts. The setting of the connecting plate 13 facilitates the connection between the lower beam column 1, the upper beam column 11 and the column base 12.

[0028] The size of the insert plate 21 is adapted to the size of the slot 23, and the insert plate 21 and the slot 23 are movably connected. By the cooperation of the insert plate 21 and the slot 23, the installation position of the crossbeam 2 can be defined.

[0029] During assembly, first align the lower beam column 1, upper beam column 11, and column base 12. Then, insert the crossbeam 2 between the two first limiting plates 22, while simultaneously inserting the insert plate 21 into the slot 23 to limit the position of the crossbeam 2. Next, push the positioning frame 3 to the left until the second limiting plate 5 abuts against the outside of the insert plate 21, thus limiting the insertion position of the insert plate 21. Finally, use bolts passing through the positioning groove 4 to connect and limit the positioning frame 3 and the connecting plate 13, thereby achieving the effect of connecting and installing the crossbeam 2. Moreover, the mortise and tenon joint reduces the height of the crossbeam 2. The installation of low-bolts, and after bolt breakage, the positioning frame 3 can slide to the outside of the beam 2 and the connecting plate 13 to provide a certain load, thereby ensuring the stability of the prefabricated building. At the same time, after the beam 2 is inserted and installed in place, the positioning frame 3 can limit the position of the column base 12 and the connecting plate 13 through the limiting groove 6, thereby facilitating the installation and connection between the lower beam column 1, the upper beam column 11 and the column base 12, and further improving the connection efficiency of the beam and column.
