Description

Technical Field

[0001] This utility model relates to the technical field of steel connection devices, and in particular to a rigid connection device for H-shaped steel beams and H-shaped steel columns. Background Technology

[0002] H-beams are widely used, mainly for: various civil and industrial building structures; various large-span industrial plants and modern high-rise buildings, especially industrial plants in areas with frequent earthquakes and under high-temperature working conditions; large bridges requiring high load-bearing capacity, good cross-sectional stability, and large spans; heavy equipment; highways; ship skeletons; mine support; foundation treatment and dam engineering; various machine components; the section modulus, moment of inertia, and corresponding strength of H-beams are significantly better than those of ordinary I-beams of the same weight.

[0003] In the prior art, the connection between H-shaped steel columns and H-shaped steel beams is generally achieved by direct welding. Direct welding results in a relatively weak connection that is easily damaged. Furthermore, the welding process is difficult due to the weight of the steel. To address the above issues, application number 202022642858.1 discloses a rigid connection device for H-shaped steel beams and H-shaped steel columns, which includes an H-shaped steel column and an H-shaped steel beam disposed on one outer surface of the H-shaped steel column. By installing L-shaped plates at the top and bottom ends of the connection between the H-shaped steel column and the H-shaped steel beam, the concave portion of the L-shaped plates effectively enhances the strength of the connection. Furthermore, triangular blocks on the inner side of the L-shaped plates increase their rigidity, extending the service life of the connected H-shaped steel column and beam. A first mounting through-hole is provided on the H-shaped steel column and beam, and a second mounting through-hole is provided on the L-shaped plate. Fixing bolts are then used to secure the L-shaped plates to the H-shaped steel column and beam through these through-holes. Finally, the L-shaped plates are welded to the H-shaped steel column and beam. This not only facilitates welding for installation workers but also enhances the overall strength of the connection.

[0004] However, a thorough reading of the aforementioned patent documents reveals the following shortcomings: In use, installation through holes are generally pre-drilled on H-shaped steel columns and H-shaped steel beams. However, since the size of the L-shaped plate is fixed, it is inconvenient to connect them when there are errors in the installation through holes on the H-shaped steel columns and H-shaped steel beams. Workers need to drill holes a second time. Moreover, since the size of the L-shaped plate is fixed, it is inconvenient to adjust it according to the actual situation. There are certain limitations and inconveniences, and there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rigid connection device for H-shaped steel beams and H-shaped steel columns.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rigid connection device for H-beams and H-columns includes H-columns, H-beams, and a connection mechanism;

[0008] The H-shaped steel column and H-shaped steel beam are provided with multiple mounting through holes. The connecting mechanism is provided on the H-shaped steel column and H-shaped steel beam and is connected to the multiple mounting through holes on the H-shaped steel column and H-shaped steel beam.

[0009] The connecting mechanism includes a connecting plate, a stop block, a first fixing rod, a second fixing rod, a first connecting rod, a second connecting rod, a threaded rod, and fixing bolts. Four fixing bolts are connected to the through holes on the H-shaped steel column and the H-shaped steel beam, and two identical connecting plates are connected to the eight fixing bolts. Through the cooperative design between the connecting plate, the stop block, the first fixing rod, the second fixing rod, the first connecting rod, the second connecting rod, the threaded rod, and the fixing bolts, the connecting mechanism can easily connect the H-shaped steel column and the H-shaped steel beam at different positions, greatly improving the flexibility of the rigid connection device.

[0010] Specifically, each of the two connecting plates is rotatably connected to a first fixing rod, and each of the two first fixing rods is fixedly connected to a second fixing rod. A first connecting rod and a second connecting rod are rotatably connected to the second fixing rod, and a threaded rod is rotatably connected to one end of the second connecting rod. One end of the threaded rod is threadedly connected to the first connecting rod. By rotating the rotating plate, the threaded rod rotates on the second connecting rod and engages in threaded transmission with the first connecting rod. This causes one end of the first connecting rod to extend the corresponding connecting plate outward by a certain distance, thereby adjusting the distance between the two connecting plate supports. This facilitates the connection of the two connecting plates to the mounting through holes at different positions on the H-shaped steel column and H-shaped steel beam.

[0011] Specifically, one end of each of the eight fixing bolts passes through the H-shaped steel column and the H-shaped steel beam, and one end of each of the eight fixing bolts is connected to a fixing nut. The connection between the fixing nut and the fixing bolt achieves the effect of limiting the position of the two connecting plates.

[0012] Specifically, each of the two connecting plates has a groove on one side, and a stop block is rotatably connected in each of the two grooves. The two stop blocks are respectively fixedly connected to one end of the two fixing rods to prevent the two fixing rods from detaching.

[0013] Specifically, a limiting nut is threaded onto the threaded rod, and the limiting nut abuts against the connecting rod. By rotating the limiting nut so that it abuts against the connecting rod, the connecting rod is limited.

[0014] Specifically, a rotating plate is fixedly sleeved on the threaded rod to facilitate rotation of the threaded rod.

[0015] Specifically, a circular plate is fixedly connected to one end of the threaded rod, and the circular plate is rotatably connected to the connecting rod to prevent the threaded rod from disengaging.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) The present invention provides a rigid connection device for H-shaped steel beams and H-shaped steel columns. Through the cooperative design of the connecting plate, the blocking block, the first fixing rod, the second fixing rod, the first connecting rod, the second connecting rod, the threaded rod and the fixing bolt, the connection mechanism can be conveniently connected to the H-shaped steel column and the H-shaped steel beam at different positions, which greatly improves the flexibility of the rigid connection device.

[0025] Reference Figure 1-4 A rigid connection device for H-beams and H-columns includes an H-column 1, an H-beam 2, and a connection mechanism.

[0026] Both the H-shaped steel column 1 and the H-shaped steel beam 2 have multiple mounting through holes. The connecting mechanism is set on the H-shaped steel column 1 and the H-shaped steel beam 2 and is connected to the multiple mounting through holes on the H-shaped steel column 1 and the H-shaped steel beam 2.

[0027] The connecting mechanism includes a connecting plate 3, a stop block 4, a first fixing rod 5, a second fixing rod 6, a first connecting rod 7, a second connecting rod 8, a threaded rod 9, and fixing bolts 11. Four fixing bolts 11 are connected to the through holes on the H-shaped steel column 1 and the H-shaped steel beam 2, respectively. Two identical connecting plates 3 are connected to the eight fixing bolts 11. Through the cooperative design between the connecting plate 3, the stop block 4, the first fixing rod 5, the second fixing rod 6, the first connecting rod 7, the second connecting rod 8, the threaded rod 9, and the fixing bolts 11, the connecting mechanism can be conveniently connected to different positions of the H-shaped steel column 1 and the H-shaped steel beam 2, greatly improving the flexibility of the rigid connection device.

[0028] In this embodiment, a first fixing rod 5 is rotatably connected to each of the two connecting plates 3. A second fixing rod 6 is fixedly connected to one end of each of the two first fixing rods 5. A first connecting rod 7 and a second connecting rod 8 are rotatably connected to the two second fixing rods 6 respectively. A threaded rod 9 is rotatably connected to one end of the second connecting rod 8. One end of the threaded rod 9 is threadedly connected to the first connecting rod 7. By rotating the rotating plate 13, the threaded rod 9 rotates on the second connecting rod 8 and performs threaded transmission with the first connecting rod 7. This causes one end of the first connecting rod 7 to drive the corresponding connecting plate 3 to extend outward by a certain distance, thereby achieving the effect of adjusting the distance within the bracket of the two connecting plates 3. This facilitates the connection of the two connecting plates 3 to the mounting through holes at different positions on the H-shaped steel column 1 and the H-shaped steel beam 2.

[0029] In this embodiment, one end of each of the eight fixing bolts 11 passes through the H-shaped steel column 1 and the H-shaped steel beam 2, and one end of each of the eight fixing bolts 11 is connected to a fixing nut 12. The connection between the fixing nut 12 and the fixing bolt 11 achieves the effect of limiting the two connecting plates 3.

[0030] In this embodiment, a groove is provided on one side of each of the two connecting plates 3, and a blocking block 4 is rotatably connected in each of the two grooves. The two blocking blocks 4 are respectively fixedly connected to one end of the two fixing rods 5 to prevent the two fixing rods 5 from detaching.

[0031] In this embodiment, a limiting nut 10 is threadedly connected to the threaded rod 9. The limiting nut 10 abuts against the connecting rod 7. By rotating the limiting nut 10 and making it abut against the connecting rod 7, the connecting rod 7 is limited.

[0032] In this embodiment, a rotating plate 13 is fixedly sleeved on the threaded rod 9 to facilitate the rotation of the threaded rod 9.

[0033] In this embodiment, a circular plate is fixedly connected to one end of the threaded rod 9, and the circular plate is rotatably connected to the connecting rod 8 to prevent the threaded rod 9 from disengaging.

[0034] Working principle: In use, the fixing bolts 11 on the two connecting plates 3 are inserted into the corresponding mounting through holes on the H-shaped steel column 1 and the H-shaped steel beam 2, respectively. Then, the fixing nut 12 is connected to the fixing bolt 11, thereby achieving the effect of limiting the two connecting plates 3. At the same time, through the transmission of fixing rod 1 5, fixing rod 2 6, connecting rod 1 7, connecting rod 2 8 and threaded rod 9, the connection between the H-shaped steel column 1 and the H-shaped steel beam 2 is achieved.

[0035] Since one end of connecting rod 7 and connecting rod 8 are movably connected to two fixed rods 6 respectively, it is possible to facilitate the connection of the two connecting plates 3 to the mounting through holes at different positions on the H-shaped steel column 1 and the H-shaped steel beam 2 respectively.

[0036] Simultaneously, by rotating the rotating plate 13, the threaded rod 9 rotates on the connecting rod 2 8 and engages in threaded transmission with the connecting rod 1 7. This causes one end of the connecting rod 1 7 to extend the corresponding connecting plate 3 outward by a certain distance, thereby adjusting the distance between the two connecting plates 3 within the bracket. This further facilitates the connection of the two connecting plates 3 with the mounting through holes at different positions on the H-shaped steel column 1 and the H-shaped steel beam 2. Then, the limiting nut 10 is rotated and abuts against the connecting rod 1 7, thereby limiting the position of the connecting rod 1 7.

[0037] Meanwhile, since the two fixed rods 5 are movably connected to the two connecting plates 3 respectively, the flexibility of the two connecting plates 3 is further improved, which makes it convenient to install the two connecting plates 3 at different positions on the H-shaped steel column 1 and the H-shaped steel beam 2 respectively, greatly improving the flexibility of the rigid connection device.

[0038] The technological advancements of this invention compared to existing technologies are as follows: the coordination of various components enables a convenient connection mechanism to connect H-shaped steel columns 1 and H-shaped steel beams 2 at different positions, greatly improving the flexibility of the rigid connection device. Moreover, the structure is simple, enhancing convenience and practicality.
