Abstract
Description
Technical Field
[0001] This utility model relates to the field of prefabricated steel structure frame technology, and in particular to a seismic-resistant prefabricated frame connection device. Background Technology
[0002] Prefabricated steel frame structures use prefabricated steel columns, beams, and supports as core load-bearing units, and are assembled on-site using standardized connection structures (bolts, flanges, end plates, etc.) to form a spatial load-bearing system. It is a combination of prefabricated and steel structure architecture, possessing multiple advantages such as industrialized production, rapid construction, and excellent structural performance.
[0003] When using existing prefabricated frame connection devices, the traditional bolt tightening process is prone to displacement, requiring multiple construction workers to work together to support the components and make repeated adjustments, which takes a long time and results in low assembly efficiency. Moreover, the connection nodes between traditional steel columns and steel beams are mostly rigid connection structures. When subjected to dynamic loads such as earthquakes and strong winds, stress concentration is likely to occur at the nodes, leading to bolt breakage, end plate deformation, or even node failure, which seriously affects the overall stability of the frame structure. Utility Model Content
[0004] This utility model relates to an earthquake-resistant prefabricated frame connection device. By engaging the positioning column with the positioning sleeve, the first fixed sleeve and the connecting end plate can be quickly positioned. At the same time, the fixed frame and the elastic plate cooperate to limit the steel beam, ensuring that the connecting end plate is aligned with the preset bolt holes of the first fixed sleeve and the steel beam. This prevents displacement during bolt tightening, avoids the need for manual repositioning, and effectively improves on-site assembly efficiency.
[0005] This utility model provides a seismic-resistant prefabricated frame connection device, specifically including: a steel column, on which a steel beam is provided; a first fixing sleeve is fitted on the steel column, and the first fixing sleeve is located at the connection between the steel column and the steel beam; connecting end plates are provided on the upper and lower sides of the end of the steel beam; a second fixing sleeve is fitted on the steel column, and the second fixing sleeve is located below the first fixing sleeve; a second fixing plate is provided at the bottom of the steel beam; and a diagonal bracing assembly is provided between the second fixing plate and the second fixing sleeve.
[0006] Furthermore, the first fixing sleeve has a rectangular cavity structure, and a positioning post is fixedly installed on the outside of the first fixing sleeve. A fixing frame is provided on the outside of the first fixing sleeve, and elastic plates are provided on the upper and lower sides of the fixing frame, and the elastic plates have a U-shaped structure.
[0007] Furthermore, the connecting end plate has an L-shaped structure, and a through groove is provided in the middle of the connecting end plate. A positioning sleeve is provided on the connecting end plate, and the positioning sleeve corresponds to the position of the through groove.
[0008] Furthermore, the connecting end plate is fixedly connected to the first fixing sleeve and the steel crossbeam by bolts, and the positioning column is engaged with the positioning sleeve frame, and the fixing frame is located on both sides of the end of the steel crossbeam, and the elastic plate is in contact with the steel crossbeam.
[0009] Furthermore, the second fixing sleeve has a rectangular cavity structure, and a first fixing plate is provided on the outside of the second fixing sleeve. The first fixing plate is fixedly connected to the second fixing sleeve by bolts, and a first connecting ear plate is provided on the first fixing plate.
[0010] Furthermore, the second fixing plate is fixedly connected to the steel crossbeam by bolts, and the second fixing plate is provided with a second connecting ear plate.
[0011] Furthermore, the diagonal brace assembly includes an adjustment frame, a mounting bracket, a first connecting ear, and a second connecting ear. The mounting bracket is fitted onto the adjustment frame. The first connecting ear is located at the bottom of the adjustment frame and is rotatably connected to the first connecting ear plate via a pin. The second connecting ear is located at the top of the mounting bracket and is rotatably connected to the second connecting ear plate via a pin.
[0012] Furthermore, the diagonal brace assembly also includes a connecting bolt, a compression spring, and a support plate. The top of the adjustment frame has two connecting bolts, which are distributed in parallel. A compression spring is fitted on the connecting bolt. A support plate is fixedly installed inside the mounting frame. The connecting bolt slides through the support plate and is controlled by a locking nut. The compression spring is supported between the adjustment frame and the support plate.
[0013] This utility model provides a seismic-resistant prefabricated frame connection device, which has the following advantages: This utility model includes a first fixing sleeve, which is engaged with the positioning sleeve frame by a positioning post. This allows the first fixing sleeve and the connecting end plate to be quickly positioned. At the same time, the fixing frame and the elastic plate work together to limit the movement of the steel beam, ensuring that the connecting end plate is aligned with the preset bolt holes of the first fixing sleeve and the steel beam. This prevents displacement during bolt tightening, avoids the need for manual repositioning, and effectively improves on-site assembly efficiency.
[0014] Furthermore, in this utility model, the adjustment frame and installation sleeve cooperate with the connecting bolt rod and support plate, and combined with the elastic support of the compression spring, the buffer can be achieved through compression deformation, avoiding stress concentration at the joint, which greatly improves the seismic buffering effect of the connection joint between the steel column and the steel beam, and ensures the overall stability of the frame structure.
