Abstract
Description
Technical Field
[0001] The utility model relates to the field of engineering seismic isolation and energy dissipation, in particular to a new type of traditional wooden structure constrained energy dissipation support with an improved beam end connection method. Background Art
[0002] There are a large number of traditional wooden structures in the residential buildings in rural areas of our country. Especially in the areas with high seismic intensity in the southwest and northwest, there are still a large number of wooden frame bearing buildings. Due to the simple construction technology, long age and inadequate maintenance, they have considerable seismic hidden dangers.
[0003] The main phenomena that traditional wooden structures will show after an earthquake are the disengagement and extraction of mortise and tenon joints, and the splitting at the component joints. It is necessary to reinforce traditional wooden structure houses both before and after an earthquake. Therefore, adopting a suitable reinforcement method is the key to enabling traditional wooden structure houses to be used safely.
[0004] The traditional reinforcement method for wooden structures is mainly to "embed" iron parts into wooden components. This reinforcement method not only causes damage to the wooden components themselves, but also is not conducive to replacement and maintenance. Therefore, this reinforcement method often causes damage to the wooden components, which in turn leads to the accelerated aging of wooden structure houses. At the same time, the "embedded" reinforcement of iron parts often cannot be automatically reset after an earthquake, and manual reset is required, resulting in an increase in the reinforcement cost. Moreover, in actual investigations, some beams are not regular in shape, making it difficult to install bolts for fixation at this time, and the fixation between the beam and the lower structure is difficult. Therefore, it is necessary to develop a reinforcement technology for wooden structure reinforcement that is simple to install, easy to replace, and has the ability to reset. Therefore, a new type of traditional wooden structure constrained energy dissipation support with an improved beam end connection method is proposed. Content of the Utility Model
[0005] To solve the above problems, the specific technical solution adopted by the utility model is as follows: A new type of traditional wooden structure constrained energy dissipation support with an improved beam end connection method, including arc-shaped steel plate I, arc-shaped steel plate II, arc-shaped steel plate III, and arc-shaped steel plate IV. The arc-shaped steel plate I and the arc-shaped steel plate II are connected by ordinary bolt I, the arc-shaped steel plate III and the arc-shaped steel plate IV are connected by ordinary bolt II, a U-shaped steel plate I is arranged between the arc-shaped steel plate II and the arc-shaped steel plate IV, a damper I is fixed on the side wall of the U-shaped steel plate I, and an irregular beam connection system is fixed at the top of the damper I.
[0006] Furthermore, the U-shaped steel plate I is in contact with the inner walls of the arc-shaped steel plate II and the arc-shaped steel plate IV, and the U-shaped steel plate I is welded to the arc-shaped steel plate II and the arc-shaped steel plate IV respectively.
[0007] Furthermore, both ends of the damper I are welded to the U-shaped steel plate I and the irregular beam connection system respectively, which increases the overall stability.
[0008] Furthermore, the irregular beam connection system includes a beam connection bottom plate, hinge I, beam connection side plate I, beam connection side plate II, and hinge II. The beam connection bottom plate is connected to the beam connection side plate I through hinge I, and the beam connection bottom plate is connected to the beam connection side plate II through hinge II. The beam connection bottom plate, hinge, and beam connection side plates can be flexibly changed according to the shape of the beam, which is more suitable for fixing irregular beams and is more convenient for fixing.
[0009] Furthermore, a number of mounting holes are provided on the surfaces of the beam connection bottom plate, beam connection side plate I, and beam connection side plate II, which can facilitate the fixed installation of them together with the irregular beam.
[0010] The beneficial effects of the present utility model are as follows:
[0011] 1. In order to better fix irregular beams, the present utility model wraps the beam with two beam connection side plates and one bottom plate, and self-tapping screws can be used for fixing at the lower bottom. The beam connection bottom plate, hinge, and beam connection side plates can be flexibly changed according to the shape of the beam, which can avoid the situation that it is difficult to drive bolts for irregular beams. Therefore, this design can play a better fixing role and solve the problem of seismic reinforcement of existing wood structures, especially the problem that it is difficult to drive bolts to fix irregular beams and the fixing of the beam to the lower structure is relatively difficult.
[0012] 2. The present utility model has a strong self-resetting ability. After an earthquake, the damper can return to its original state, driving the arc plate. The arc plate transmits the restoring force to the column, so that the house can return to its original state. At the same time, the present utility model can play a role in strengthening irregular beam members, and the overall structure occupies less space and does not affect normal living.

[0021] As Figures 1-5 shown, this embodiment provides a new type of traditional wood structure constraint energy dissipation support for improving the beam end connection method, including arc-shaped steel plate I 1, arc-shaped steel plate II 3, arc-shaped steel plate III 4, and arc-shaped steel plate IV 6. Arc-shaped steel plate I 1 and arc-shaped steel plate II 3 are connected by ordinary bolt I 2. Arc-shaped steel plate III 4 and arc-shaped steel plate IV 6 are connected by ordinary bolt II 5. A U-shaped steel plate I 7 is arranged between arc-shaped steel plate II 3 and arc-shaped steel plate IV 6. A damper I 8 is fixed on the side wall of the U-shaped steel plate I 7. The top end of the damper I 8 is fixed with an irregular beam connection system. The U-shaped steel plate I 7 is in contact with the inner walls of the arc-shaped steel plate II 3 and the arc-shaped steel plate IV 6, and the U-shaped steel plate I 7 is welded to the arc-shaped steel plate II 3 and the arc-shaped steel plate IV 6 respectively. The two ends of the damper I 8 are welded to the U-shaped steel plate I 7 and the irregular beam connection system respectively. The irregular beam connection system transmits the load to the damper I 8, causing the damper I 8 to deform and dissipate energy, thereby driving the U-shaped steel plate I 7. The U-shaped steel plate I 7 transmits the restoring force to the column, so that the house returns to its original state. This structure can be adapted to the irregular-shaped beam wood frame structure, occupies a small space, and is convenient for inspection and replacement, providing a new idea for the seismic reinforcement of wood structure buildings.
[0022] The irregular beam connection system includes a beam connection bottom plate 9, a hinge I 10, a beam connection side plate I 11, a beam connection side plate II 12, and a hinge II 13. The beam connection bottom plate 9 is connected to the beam connection side plate I 11 through the hinge I 10, and the beam connection bottom plate 9 is connected to the beam connection side plate II 12 through the hinge II 13. A number of mounting holes are provided on the surfaces of the beam connection bottom plate 9, the beam connection side plate I 11, and the beam connection side plate II 12. The irregular beam connection system wraps around the beam and can be fixed through self-tapping screws on the beam connection bottom plate 9. The hinge I 10 and the beam connection side plates I 11 and II 12 vary according to the situation of the beam, avoiding the situation where it is difficult to drive bolts into the irregular beam structure. This design can play a better fixing role.
[0023] When using the novel restraint energy dissipation brace for traditional wood structures in this technical solution, first, the arc-shaped steel plate I 1 and the arc-shaped steel plate II 3 are connected through the ordinary bolt I 2, and the arc-shaped steel plate III 4 and the arc-shaped steel plate IV 6 are connected through the ordinary bolt II 5, and it is fixed on the columns of the house. Then, the irregular beam connection system is fixed on the regular beam or the irregular beam to complete the stable installation. The damper I 8 can return to its original state after an earthquake, driving the arc-shaped plate. The arc-shaped plate transmits the restoring force to the column body, so that the house returns to its original state. The beam connection bottom plate 9, the beam connection side plate I 11, and the beam connection side plate II 12 can play a role in wrapping and strengthening the irregular beam members and will not damage the wood structure body during installation. The overall structure occupies a small space and will not affect normal living.
[0024] The above is the preferred implementation manner of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
