Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and particularly relates to an H-shaped beam and column reinforced rigid connection node. Background Art

[0002] H-beams can not only withstand heavy vertical loads, but also horizontal loads, and are therefore often used in the construction industry, machinery manufacturing, and transportation. Although H-beams can be directly connected to support columns by welding or bolting, the connection points between the beams and columns lack additional support. Therefore, when subjected to large loads or earthquakes, the connection points are prone to damage. Therefore, connection nodes are needed to connect the H-beams and support columns to distribute the load and reduce stress concentration at the connection points.

[0003] A search revealed a beam-column rigid joint with prior art publication number CN219157987U. In this device, an L-shaped bent plate passes through an upper through-hole on the upper plate and a beam through-hole on the beam, and is inserted into a block connection hole on the lower block. An L-shaped bent rod on the lower block cooperates with a spring to secure the L-shaped bent plate. However, when the beam and column are subjected to force and vibrate, the L-shaped bent plate and the beam through-hole in the device collide and rub against each other, potentially thinning the L-shaped bent plate or enlarging the beam through-hole, affecting the stability of the joint. In more serious cases, the L-shaped bent plate may break, causing the beam to detach from the supporting column.

[0004] After searching, the prior art announcement number CN222120509U is a rigid connection node device for steel pipe columns and steel beams. The device is fixedly connected to the connection node body with a first connection steel plate and a second connection steel plate welded at the top and bottom respectively by a steel beam connection steel plate, and the long side end face of the fixed reinforcement plate is perpendicularly welded to the side end face of the connection node body, and its two short side faces respectively contact the surfaces of the first connection steel plate and the second connection steel plate and are welded and fixed to form an I-shaped surface; the steel beam connection steel plate is welded and fixed to the I-shaped surface, and the steel beam is connected to the steel beam connection steel plate by bolts; however, the connection points of a steel beam connected to the node by bolts are all located on the vertical plane of the end of the steel beam, and no support is provided in other directions. Therefore, when subjected to increased load, the connection points are easily damaged or the steel beam is deformed;

[0005] Therefore, a reinforced rigid connection node between H-beams and columns is needed, which can prevent deformation and damage of the node or H-beam while adding auxiliary support to improve the stability of the connection between the H-beam and H-column. Summary of the Invention

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and provide an H-beam and column reinforced rigid connection node. The utility model uses a limiting device to prevent the H-beam from being displaced due to vibration or the parts in the friction device from being worn and deformed; at the same time, the connecting frame and the supporting device cooperate to support the H-beam, thereby improving the stability of the connection between the H-beam and the H-column.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] The cam is secured to the top of the H-shaped column by a spring, and the cam is secured to the bottom of the H-shaped column by a spring.

[0009] The limiting mechanism is provided with a connecting plate, a connecting block, a limiting plate, and a sliding shaft; the sliding shafts at both ends of the connecting plate are located on one side of the spring and are slidably connected to the connecting box; the limiting plate is fixedly connected to one end of the connecting plate; the connecting block is located inside the support seat and fits with the push block, and one end of the connecting block passes through the slide groove on the support seat and is fixedly connected to the connecting plate.

[0010] The connecting frames are provided with two groups, and the two groups of connecting frames are symmetrically fixed on both sides of the guide plate by bolts, and the connecting grooves are fixedly connected to the bottom of the connecting frames.

[0011] The supporting device includes a connecting seat I, a threaded rod I, a threaded sleeve, a threaded rod II, a sliding seat, and a fixed seat; the connecting seat I is located below the supporting seat and is fixedly connected to the H-shaped column; the threaded rod I and the threaded rod II are respectively threadedly connected to the two ends of the threaded sleeve, and the threads on the threaded rod I and the threaded rod II turn in opposite directions, and one end of the threaded rod I is rotatably connected to the connecting seat I through the connecting seat, and one end of the threaded rod II is rotatably connected to the sliding seat through the connecting seat; a pair of fixed seats are provided, and the pair of fixed seats are symmetrically fixed to the two ends of the sliding seat by bolts.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1) Bolt I in the limit device drives the push block to press the connecting block downward, so that the connecting block controls the connecting plate to drive the sliding shaft to squeeze the spring, so that one end of the limit plate can adapt to fit the vertical plate on the inner side of the H-beam of different thicknesses, limiting the H-beam to prevent the H-beam from displacement due to vibration or wear and deformation of parts in the friction device, resulting in a decrease in the stability of the node.

[0014] 2) The connecting grooves at the bottom of the two sets of connecting frames are symmetrically fitted on both sides of the horizontal plate at the top of the H-beam, and then the connecting frames are fixedly connected to the guide plates by bolts; then the threaded sleeve in the support device is rotated to rotate the threaded rods I and II out of the threaded sleeve until the connecting grooves on the inner side of the fixing seat are aligned with both sides of the horizontal plate at the bottom of the H-beam, and then the pair of fixing seats are controlled to move closer to each other until the connecting grooves on the fixing seats are close to both sides of the horizontal plate at the bottom of the H-beam, and then the fixing seats are fixedly connected to the sliding seats by bolts; the connecting frame and the support device cooperate to support the H-beam, thereby reducing the number of through holes on the H-beam, preventing the through holes from weakening the strength of the H-beam, and at the same time reducing the deformation caused by the middle part of the H-beam when subjected to force, thereby improving the stability of the connection between the H-beam and the H-column.
