Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of ancient building wood structure reinforcement, and specifically discloses a tower-type wood column frame interlayer anti-seismic reinforcement system with adjustable energy dissipation and enhancement. BACKGROUND

[0002] As an important form of traditional buildings, tower-type wood structures, as shown in the drawings, have the structural feature of being composed of inner and outer groove columns to form a space system similar to a modern tube-in-tube. Figure 17 The upper and lower ends of the columns are connected by mortise and tenon joints, and the transverse connection between the inner and outer groove columns is weak, mainly relying on the limited constraint provided by the upper bracket. The connection between the bracket and the horizontal beam becomes a weak position. Under the action of an earthquake, this structure is prone to overturning damage along the inner and outer groove directions due to its poor overall performance and insufficient lateral stiffness, and has obvious seismic safety hazards.

[0003] Currently, to improve the seismic performance of such wood structures, the commonly used reinforcement measures are to set various types of diagonal bracing members between the columns. However, the arrangement of the diagonal bracing members often occupies the space between the inner and outer grooves, which is usually used as a tourist passage in actual use, resulting in a conflict between the reinforcement scheme and the building use function, and the applicability is limited. In addition, most of the existing reinforcement methods fail to fully consider the inherent seismic mechanism of traditional wood structures, especially the energy conversion effect brought by column rocking, i.e. converting part of the earthquake input energy into gravitational potential energy through the rocking of the column body, thereby reducing the damage to the main structure. In the current reinforcement measures, the structure damping is greatly improved by adding dampers and the like, which to some extent suppresses the vibration response, but hinders the rocking behavior and self-resetting capability of the column body, destroys the original energy dissipation mechanism of the wood structure, and may even cause local stress concentration or aggravate component damage, which is not conducive to the improvement of overall seismic toughness. Therefore, a reinforcement system that can enhance energy dissipation without affecting the use function and self-resetting characteristics is needed. SUMMARY

[0004] In view of the problems of weak connection between the inner and outer groove columns in the existing tower-type wood structure in seismic reinforcement, the influence of reinforcement measures on the use function, and the destruction of the original rocking energy dissipation mechanism of the tower-type wood structure, the application provides a tower-type wood column frame interlayer anti-seismic reinforcement system with adjustable energy dissipation and enhancement, which can improve the structural bearing capacity, stiffness and energy dissipation capacity while retaining the rocking self-resetting characteristics of the wood column and adapting to the adjustment requirements of different damage states and structural sizes.

[0051] The adjusting plate II 26, the adjusting plate friction sheet 33 and the adjusting plate jacking bolt 34 constitute an adjustable friction mechanism, which provides adjustable friction force by jacking up the adjusting plate friction sheet 33 through the adjusting plate jacking bolt 34, can dissipate energy in sliding, and can force the dovetail mortise joint to participate in extrusion and dowel extraction to dissipate energy when the friction is large, thereby providing a controllable energy dissipation mechanism through the synergistic effect of the dovetail mortise joint: when the wooden column 42 is slightly damaged, the adjusting plate jacking bolt 34 is rotated to reduce the jacking force between the adjusting plate friction sheet 33 and the adjusting plate II 26, allowing the column body to swing moderately and dissipating energy through friction sliding; when the column body is significantly tilted, the friction force is increased to limit the swing amplitude and prevent overturning; when the adjustable friction mechanism is limited in sliding, the dovetail mortise joint further dissipates energy through extrusion and dowel extraction.

[0052] As shown in Figure 3 , 12As shown in FIGS. 14, 15, the dovetail beam connector further comprises an upper pressing block friction plate 35, an upper pressing block jacking bolt 36, a side pressing block friction plate I 37, a side pressing block jacking bolt I 38, a side pressing block friction plate II 39, and a side pressing block jacking bolt II 40; the web of the dovetail beam upper pressing plate 28 is provided with a through hole, and a nut is fixed on the through hole by welding; the upper pressing block friction plate 35 is located between the dovetail beam upper pressing plate 28 and the upper pressing block 29; the upper pressing block jacking bolt 36 passes through the nut and the through hole on the dovetail beam upper pressing plate 28 to jacks up the upper pressing block friction plate 35; the back plate of the pressing block placing rack 27 is provided with a through hole, and a nut is fixed on the through hole by welding; the side pressing block friction plate I 37 is located between the back plate of the pressing block placing rack 27 and the side pressing block 30; the side pressing block jacking bolt I 38 passes through the nut and the through hole on the back plate to jacks up the side pressing block friction plate I 37; the side plate of the pressing block placing rack 27 is provided with a through hole, and a nut is fixed on the through hole by welding; the side pressing block friction plate II 39 is located between the side plate of the pressing block placing rack 27 and the side pressing block 30; the side pressing block jacking bolt II 40 passes through the nut and the through hole on the side plate to jacks up the side pressing block friction plate II 39. The jacking bolts apply jacking force to each friction plate, so as to realize the close adhesion of the wooden pressing block and the dovetail beam connector.

[0053] The installation process of the adjustable energy dissipation enhanced story-type wood column inter-story seismic reinforcement system is as follows.

[0054] First, assemble the components of the adjustable beam reinforcement system between the common purlins, then clamp the common purlin bayonet in the common purlin 41, tighten the common purlin jacking bolt 8 and the wood beam jacking bolt 18, and press the common purlin friction plate 7 and the wood beam friction plate 17 respectively, so that the inner and outer pressing structures 5 and 6 are tightly connected with the common purlin 41 and the wood beam 1 is tightly connected with the surrounding steel components. The system is naturally in place under the action of its own weight without applying artificial initial deformation to eliminate the initial internal force caused by the weight; after the position is stable, tighten the limiting nuts I 3 on both sides of the adjusting plate I 11 to lock the transition screw I 2 and limit its movement in the adjusting hole I.

[0055] Then assemble the components of the adjustable energy dissipation enhanced reinforcement system between the columns, install the hoop half ring 22 on the wood column 42, and then tighten the upper pressing block jacking bolt 36, the side pressing block jacking bolt I 38, and the side pressing block jacking bolt II 40 to press the wooden pressing block through the upper pressing block friction plate 35, the side pressing block friction plate I 37, and the side pressing block friction plate II 39, and ensure that it is tightly adhered to the steel component; the system also relies on its own weight to naturally level, without artificial attitude adjustment; after the initial state is determined, adjust the tightening amount of the adjusting plate jacking bolt 34 according to the actual damage condition of the wood column 42 to control the pressing force between the adjusting plate friction plate 33 and the adjusting plate II 26, and then set the friction energy dissipation level. If the wood column 42 is slightly damaged, reduce the pressing force to retain the column body sway and self-resetting ability; if the wood column 42 has been significantly tilted, increase the pressing force to limit the sway amplitude and prevent collapse.

[0056] The adjusting hole I and the adjusting hole II are both long circular holes, which are used for adjusting the distance between the universal sill 41 or the wooden column 42 with different intervals, and adapting to the structural differences. On the other hand, the adjusting hole II allows the transition screw rod II 20 to have a slight rotation and slip in the hole, releases the excessive constraint on the column swing in the earthquake, allows the adjacent wooden columns 42 to produce different swing in the earthquake, and guarantees the self-resetting mechanism of the tower-type wooden structure in the swing to convert the seismic energy into gravitational potential energy.
