Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and specifically relates to a replaceable box-end plate energy dissipation beam. Background Technique

[0002] In recent years, with the update and development of technology, China's building structures have made achievements in earthquake resistance. And with further research, many new earthquake-resistant structures have emerged, including the development of replaceable energy dissipation beams.

[0003] The energy dissipation beam plays a role in improving the earthquake resistance of the structure, and can ensure that the main structure remains in the elastic stage without being damaged during an earthquake. However, for earthquake-prone areas, if the energy dissipation beam is fixedly connected to the main structure, the protection of the structure is mostly one-time, which is always unsafe for the structure and will increase the cost of building reconstruction and repair. Therefore, the replaceable energy dissipation beam came into being, reducing the repair cost by replacing the energy dissipation beam components, and at the same time reducing the workload during repair. For example, the invention patent with the publication number CN104929310A discloses "a replaceable energy dissipation beam", which achieves the purpose of replacement by replacing the angle steel between the main body and the energy dissipation beam to disperse earthquake energy through the angle steel.

[0004] However, most energy dissipation beam segments are borne by the main structure or the energy dissipation components on the structure, and the replacement process may lead to complicated construction procedures, resulting in a slow repair project. Content of the Utility Model

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0044] Please refer to Figures 1 to 9 , in the embodiment of the present invention, a replaceable box-end plate energy-dissipating beam includes a box-shaped steel beam 1, an end plate 2 and a stiffening web 3. The box-shaped steel beam 1 accounts for the main part, mainly a box-shaped H-shaped non-yielding short steel beam;

[0045] The end plate 2 is a steel plate with the same strength as the box-shaped steel beam 1, on which a plurality of bolt holes 4 are evenly arranged. The end plate 2 is fixedly connected to the end of the box-shaped steel beam 1, and the end plate 2 is fixedly connected to the main structure through high-strength bolts passing through the bolt holes 4;

[0046] The stiffening web 3 is a thin plate with the same strength as the box-shaped steel beam 1, and it is welded to the box-shaped steel beam 1.

[0047] In this solution, under the expected seismic action, the energy-dissipating beam yields first to protect the main structure, and the main structure remains elastic.

[0048] After the earthquake, only the energy-dissipating beam part needs to be replaced, and there is no need to replace the entire beam section. Since the energy-dissipating beam part is relatively short, the economic benefit is relatively high and the repair workload is small. Moreover, both the energy-dissipating beam section and the main structure are connected by high-strength bolts, so the structural function can be quickly restored.

[0049] Due to the addition of the stiffening web 3, the energy-dissipating beam section can adapt to the main structure during normal use and help the structure bear the load. Under the action of an earthquake, it can also help dissipate energy, so that the strength of the energy-dissipating beam section will not be too low.

[0050] As a further solution of the present utility model, the end plate 2 and the box-shaped steel beam 1 are fixedly connected by welding.

[0051] In this embodiment, since the end plate 2 and the box-shaped steel beam 1 are welded, the weld is a butt weld with secondary quality penetration, and the weld is a fillet weld of 10×10.

[0052] As a further solution of the present utility model, the end plate 2 and the box-shaped steel beam 1 are detachably and fixedly connected by a connecting mechanism, wherein the connecting mechanism includes a buckle assembly, a limiting assembly and a reset assembly.

[0053] In this embodiment, the method of fixedly connecting the end plate 2 and the box-shaped steel beam 1 by the connecting mechanism can not only quickly complete the loading and unloading operation, but also avoid the possible incomplete welding situation when using the welding method, improve the safety and reduce the operation difficulty at the same time;

[0054] Among them, by the mutual cooperation of the buckle assembly, the limiting assembly and the reset assembly, the quick loading and unloading of the end plate 2 and the box-shaped steel beam 1 can be realized.

[0055] As a further solution of the present utility model, the buckle assembly includes an L-shaped plate 5 fixedly connected to one end of the box-shaped steel beam 1 and a cross plate 6 horizontally fixedly connected to one end of the end plate 2, and the L-shaped plate 5 and the cross plate 6 are mutually attached;

[0056] A wedge-shaped installation hole 7 is vertically penetrated through the cross plate 6, and a wedge-shaped installation post 8 is vertically fixedly arranged on the L-shaped plate 5, and the bottom end of the wedge-shaped installation post 8 vertically penetrates through the wedge-shaped installation hole 7.

[0057] In this embodiment, since the L-shaped plate 5 and the cross plate 6 are respectively fixedly connected to the box-shaped steel beam 1 and the end plate 2, and the wedge-shaped installation post 8 fixed on the L-shaped plate 5 vertically penetrates through the wedge-shaped installation hole 7 opened on the cross plate 6, the L-shaped plate 5 and the cross plate 6 are locked in the horizontal direction, that is, the horizontal locking of the box-shaped steel beam 1 and the end plate 2 is realized.

[0058] As a further solution of the present utility model, the limiting component includes a clamping block 10 and a sliding groove 9 horizontally and inwardly opened along one side of the inclined surface of the wedge-shaped mounting post 8, and the clamping block 10 is slidably engaged with the sliding groove 9;

[0059] The top surface of the clamping block 10 is set as a plane, and the top surface of the clamping block 10 abuts against the bottom surface of the cross plate 6, and the bottom of the clamping block 10 is set as a wedge shape.

[0060] The limiting component further includes a sleeve 11 and a sliding rod 12 slidably engaged with the sleeve 11. One end of the sleeve 11 is horizontally and fixedly connected to the inner side wall of the sliding groove 9, and one end of the sliding rod 12 is fixedly connected to one side of the clamping block 10;

[0061] A spring 13 is arranged inside the sleeve 11, and both ends of the spring 13 abut against the inner side wall of the sleeve 11 and the other end of the sliding rod 12 respectively.

[0062] In this embodiment, due to the existence of the spring 13 and being in a compressed state, when there is no external force, the sliding rod 12 will drive the clamping block 10 to always have a tendency to move outwards from the sliding groove 9;

[0063] Also, because the top surface of the clamping block 10 is set as a plane and the top surface of the clamping block 10 abuts against the bottom surface of the cross plate 6, the clamping block 10 will be vertically buckled with the cross plate 6, so that the wedge-shaped mounting post 8 cannot move vertically upwards, that is, the wedge-shaped mounting post 8 cannot be removed from the wedge-shaped mounting hole 7;

[0064] During installation, the wedge-shaped mounting post 8 is vertically penetrated through the wedge-shaped mounting hole 7, so that the L-shaped plate 5 and the cross plate 6 are attached to each other, that is, the wedge-shaped mounting post 8 cannot continue to move downwards. During this process, due to the bottom of the clamping block 10 being set as a wedge shape, the wedge-shaped mounting hole 7 will squeeze the clamping block 10, so that the clamping block 10 contracts into the inside of the sliding groove 9. When the clamping block 10 moves out of the wedge-shaped mounting hole 7, under the action of the spring 13, it will move out of the sliding groove 9 again, so that the top surface of the clamping block 10 abuts against the bottom surface of the cross plate 6.

[0065] As a further solution of the present utility model, the reset component includes a limiting sliding column 18. A groove 14 is opened on the side wall of the wedge-shaped mounting post 8, and an L-shaped sliding groove 15 communicating with the sliding groove 9 is arranged on the inner side wall of the groove 14;

[0066] A T-shaped sliding groove 16 is vertically opened on the side wall of the clamping block 10. A T-shaped sliding block 17 is slidably engaged inside the T-shaped sliding groove 16. The limiting sliding column 18 is located inside the L-shaped sliding groove 15 and is slidably engaged with each other. One end of the limiting sliding column 18 is fixedly connected to the T-shaped sliding block 17, and the other end of the limiting sliding column 18 extends into the groove 14.

[0067] In this embodiment, during disassembly, first, an external force is used to drive the limit sliding column 18 to horizontally slide inside the L-shaped sliding groove 15. During this process, the limit sliding column 18 will cause the clamping block 10 to retract into the inside of the sliding groove 9 through the interaction of the T-shaped slider 17 and the T-shaped sliding groove 16. At the same time, the spring 13 will be further compressed. Then, an external force is used to drive the limit sliding column 18 to move vertically upward and then the external force is removed. At this time, under the action of the spring 13, the limit sliding column 18 will be buckled with the L-shaped sliding groove 15, so that the clamping block 10 is always located inside the sliding groove 9, and the wedge-shaped mounting column 8 can be vertically removed from the wedge-shaped mounting hole 7. In addition, during the process of the limit sliding column 18 moving vertically upward, it will drive the T-shaped slider 17 to slide cooperatively with the T-shaped sliding groove 16.

[0068] As a further solution of the present utility model, the box steel beam 1, the end plate 2, and the stiffening web 3 are all Q235 strength steel plates;

[0069] The number of high-strength bolts used for connecting with the main structure meets the requirements of the axial force, shear force, etc. that the energy-dissipating beam needs to transfer, ensuring that the main structure can be well protected when the energy-dissipating beam comes into play.

[0070] In this embodiment, the energy-dissipating beam is transported to the construction site and connected using high-strength bolts.

[0071] Under the expected seismic action, part of the seismic energy is dissipated by the support first, and the remaining part acts on this example. When the action is large, this example will yield first, thereby dissipating the remaining seismic energy and protecting the main structure to remain in an elastic state. After replacing this example, the structure resumes its normal use state.
