Description

Technical Field

[0001] This invention belongs to the technical field of ancient building wooden structure reinforcement, and specifically discloses an adjustable energy-consuming and enhanced seismic reinforcement system for pavilion-style wooden column frames. Background Technology

[0002] The pavilion-style wooden structure, as an important form of traditional architecture, such as... Figure 17 As shown, its structural characteristics are manifested in a spatial system similar to a modern tube-in-tube structure, formed by inner and outer groove columns. This type of timber structure uses mortise and tenon joints at both the top and bottom of the columns. However, the lateral connection between the inner and outer groove columns is weak, relying mainly on the purlins in the upper bracket system for limited constraint. The connection between the bracket system and the purlin becomes a weak point. Under seismic loads, this structural form, due to its poor overall integrity and insufficient lateral stiffness, is prone to overturning failure along the inner and outer groove directions, posing a significant seismic safety hazard.

[0003] Currently, to improve the seismic performance of this type of timber structure, the common reinforcement measure is to install various diagonal bracing components between the columns. However, the arrangement of these bracing components often occupies the space between the inner and outer channels, an area typically used as a visitor passageway in practice. This creates a conflict between the reinforcement scheme and the building's functional use, limiting its applicability. Furthermore, most existing reinforcement methods fail to fully consider the inherent seismic resistance mechanisms of traditional timber structures, particularly the energy conversion effect caused by column swaying—that is, the conversion of some seismic input energy into gravitational potential energy through column swaying, thereby mitigating damage to the main structure. Current reinforcement methods often significantly increase structural damping by adding dampers, which, while suppressing vibration response to some extent, also hinders the column's swaying behavior and self-resetting ability, disrupting the original energy dissipation mechanism of the timber structure. This may instead cause localized stress concentration or exacerbate component damage, hindering the improvement of overall seismic toughness. Therefore, a reinforcement system that can enhance energy dissipation without affecting functional use and self-resetting characteristics is needed. Summary of the Invention

[0004] To address the problems of weak connections between inner and outer columns, the impact of reinforcement measures on functionality, and the disruption of the original swaying energy dissipation mechanism in the seismic reinforcement of existing pavilion-style wooden structures, this invention provides an adjustable energy-dissipating enhanced seismic reinforcement system for pavilion-style wooden columns.

[0033] like Figure 3 , 11 As shown in Figure 12, the transition piece II also includes an adjusting plate friction plate 33 and an adjusting plate tightening bolt 34; the rib plate II 25 is provided with a through hole and a nut is fixed to the through hole by welding; the adjusting plate friction plate 33 is located between the adjusting plate II 26 and the rib plate II 25; the adjusting plate tightening bolt 34 passes through the nut and the through hole on the rib plate II 25 and tightens the adjusting plate friction plate 33.

[0034] Adjustable friction mechanism is formed by adjusting plate II 26, adjusting plate friction plate 33, and adjusting plate tightening bolt 34. Adjustable friction force is provided by adjusting plate tightening bolt 34 pressing adjusting plate friction plate 33. It can dissipate energy during sliding and force dovetail joints to participate in compression and pulling to dissipate energy under extreme friction. It works in conjunction with dovetail joints to provide a controllable energy dissipation mechanism: when the wooden column 42 is slightly damaged, rotating adjusting plate tightening bolt 34 reduces the clamping force between adjusting plate friction plate 33 and adjusting plate II 26, allowing the column to sway moderately and dissipate energy through frictional sliding; when the column is significantly tilted, the friction force is increased to limit the swaying amplitude and prevent overturning; when the sliding of the adjustable friction mechanism is restricted, the dovetail joints further dissipate energy through compression and pulling.

[0035] like Figure 3 , 12As shown in Figures 14 and 15, the dovetail beam connector also includes an upper pressure block friction plate 35, an upper pressure block tightening bolt 36, a side pressure block friction plate I 37, a side pressure block tightening bolt I 38, a side pressure block friction plate II 39, and a side pressure block tightening bolt II 40; the web of the upper pressure plate 28 of the dovetail beam has a through hole, and a nut is fixed to the through hole by welding; the upper pressure block friction plate 35 is located between the upper pressure plate 28 and the upper pressure block 29 of the dovetail beam; the upper pressure block tightening bolt 36 passes through the nut and the through hole on the upper pressure plate 28 of the dovetail beam, and tightens the upper pressure block friction plate 35; the pressure block is placed The back panel of frame 27 has a through hole, and a nut is fixed to the through hole by welding. Side pressure block friction plate I 37 is located between the back panel of the pressure block placement frame 27 and the side pressure block 30. Side pressure block tightening bolt I 38 passes through the nut and through hole on the back panel, tightening the side pressure block friction plate I 37. The side panel of the pressure block placement frame 27 has a through hole, and a nut is fixed to the through hole by welding. Side pressure block friction plate II 39 is located between the side panel of the pressure block placement frame 27 and the side pressure block 30. Side pressure block tightening bolt II 40 passes through the nut and through hole on the side panel, tightening the side pressure block friction plate II 39. The tightening bolts apply a tightening force to each friction plate, achieving a tight fit between the wooden pressure block and the dovetail tenon beam connector.

[0036] The installation process of the above-mentioned adjustable energy-saving enhanced loft-style wooden column frame seismic reinforcement system is as follows.

[0037] First, assemble the components of the adjustable crossbeam reinforcement system between the purlins. Then, snap the purlin clips onto the purlin 41, tighten the purlin top bolts 8 and the wooden crossbeam top bolts 18, and apply pressure to the purlin friction plate 7 and the wooden crossbeam friction plate 17 respectively, so that the inner pressing structure 5 and the outer pressing structure 6 are tightly connected to the purlin 41, and the wooden crossbeam 1 is tightly connected to the surrounding steel components. The system will naturally take place under its own weight without applying any artificial initial deformation, so as to eliminate the initial internal force caused by its own weight. After the position is stable, tighten the limit nuts I3 on ​​both sides of the adjusting plate I11 and lock the transition screw I2 to restrict its movement in the adjusting hole I.

[0038] Then, assemble the components of the adjustable energy-dissipating reinforcement system between columns. Install the clamp half-ring 22 on the wooden column 42, and then tighten the upper pressure block tightening bolt 36, side pressure block tightening bolt I 38, and side pressure block tightening bolt II 40. The wooden pressure block is pressed tightly by the upper pressure block friction plate 35, side pressure block friction plate I 37, and side pressure block friction plate II 39 to ensure a tight fit with the steel component. The system also relies on its own weight to level itself naturally without any manual posture adjustment. After the initial state is determined, adjust the tightening amount of the adjusting plate tightening bolt 34 according to the actual damage condition of the wooden column 42 to control the clamping force between the adjusting plate friction plate 33 and the adjusting plate II 26, thereby setting the friction energy dissipation level. If the damage to the wooden column 42 is minor, reduce the clamping force to retain the column's swaying and self-resetting ability; if the wooden column 42 is obviously tilted, increase the clamping force to limit the swaying amplitude and prevent collapse.

[0039] Both adjustment hole I and adjustment hole II are oblong holes. On the one hand, they are used to adjust the distance between the purlins 41 or wooden columns 42 with different spacing to adapt to structural differences. On the other hand, adjustment hole II allows the transition screw II 20 to rotate and slide slightly within the hole, releasing excessive constraints on the swaying of the column during an earthquake. It also allows adjacent wooden columns 42 to sway asynchronously during an earthquake, ensuring the self-resetting mechanism of the pavilion-style wooden structure in converting seismic energy into gravitational potential energy during swaying.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
