[0029] The present application provides a kind of timber member reinforcing joint structure, Figures 1 to 6 The present application provides a kind of timber member reinforcing joint structure.

[0030] As Figures 1 to 3 shown in the utility model embodiment provides a kind of wood component reinforcing node structure 100, including connecting assembly 1, column connecting plate 2 possibly set on wood column and beam connecting plate 3 possibly set on wood beam, the connecting assembly 1 includes L-shaped plate 11 and at least two friction plates 12, the L-shaped plate 11 includes sequentially connected first connecting section 111, second connecting section 112 and third connecting section 113, one of the friction plate 12 is connected with the column connecting plate 2 by bolt, and its side is connected with the first connecting section 111, another friction plate 12 is connected with the beam connecting plate 3 by bolt, and its side is connected with the third connecting section 113.

[0031] In the utility model, the connecting assembly 1 includes L-shaped plate 11 and at least two friction plates 12, the L-shaped plate 11 includes sequentially connected first connecting section 111, second connecting section 112 and third connecting section 113, one of the friction plate 12 is connected with the column connecting plate 2 by bolt, and its side is connected with the first connecting section 111, another friction plate 12 is connected with the beam connecting plate 3 by bolt, and its side is connected with the third connecting section 113. The wood column and the wood beam are connected by mortise and tenon, and are reinforced and connected by the wood component reinforcing node structure 100, when the mortise and tenon node is damaged, the wood beam is bent downward under the action of dead weight, first segment energy dissipation is carried out by the deformation of the second connecting section 112 of the L-shaped plate 11, since the column connecting plate 2, the beam connecting plate 3 and two friction plates 12 are all provided with enlarged round holes, the column connecting plate 2 and the friction plate 12 are connected by bolt passing through the enlarged round holes on the column connecting plate 2 and the friction plate 12, and the beam connecting plate 3 and the other friction plate 12 are connected by another bolt passing through the enlarged round holes on the beam connecting plate 3 and the other friction plate 12, since the aperture of the enlarged round hole is larger than that of ordinary connecting hole, the bolt has a larger deformation space, second segment energy dissipation is carried out by the deformation of the bolt, so the two segment energy dissipations of the second connecting section 112 and the bolt avoid the wood beam and the wood column from being disconnected, and the energy dissipation capacity of the wood component reinforcing node structure 100 is improved. The wood component reinforcing node structure 100 provided by the utility model solves the problem of weak node energy dissipation capacity of the existing reinforcing node structure.

[0032] It should be noted that it can also be set to first segment energy dissipation is carried out by the deformation of the bolt connecting one of the friction plates 12 and the column connecting plate 2 and the bolt connecting the other friction plate 12 and the beam connecting plate 3, and second segment energy dissipation is carried out by the deformation of the second connecting section 112 of the L-shaped plate 11.

[0033] The shape of the second connecting section 112 is not limited, as long as the second connecting section 112 can deform and dissipate energy. For example, in some embodiments, as shown in Figure 1 the second connecting section 112 is arranged in an arc shape. In this way, compared with a right-angled bending section, the arc-shaped second connecting section 112 is less likely to break when deformed.

[0034] Preferably, in some embodiments, as shown in Figure 4 the first connecting section 111, the second connecting section 112, and the third connecting section 113 are integrally formed. In this way, compared with the connecting sections welded to each other, the structure has higher strength and is less likely to break when deformed.

[0035] To improve the energy dissipation capacity of the wood member reinforced joint structure 100, in some embodiments, as shown in Figure 1 two column connecting plates 2 are provided, the column connecting plates 2 are arranged at intervals, one end of the beam connecting plate 3 is connected to one column connecting plate 2 through one connecting assembly 1, and the other end is connected to the other column connecting plate 2 through the other connecting assembly 1. By adding a set of column connecting plates 2 and connecting assemblies 1, when the mortise and tenon joint is damaged and the wood beam bends downward under its own weight, the second connecting section 112 of the L-shaped plate 11 above the wood beam is stretched and deformed, and exerts a pulling force on the beam connecting plate 3. The second connecting section 112 of the L-shaped plate 11 below the wood beam is compressed and deformed, and exerts a supporting force on the beam connecting plate 3. Through the deformation of the second connecting section 112 and the bolt in the two connecting assemblies 1, the energy dissipation capacity of the wood member reinforced joint structure 100 is doubled.

[0036] Further, in some embodiments, as shown in Figure 1 the friction plate 12 is provided with a support block 15 at one end close to the second connecting section 112. In this way, when the second connecting section 112 of the L-shaped plate 11 below the wood beam is compressed and deformed, the support block 15 abuts against the second connecting section 112 and exerts a supporting force on the second connecting section 112, improving the deformation energy dissipation capacity of the second connecting section 112 and thus the energy dissipation capacity of the wood member reinforced joint structure 100.

[0037] The connection mode of the column connecting plate 2 and the beam connecting plate 3 with the wood column and the wood beam is not limited, for example, in some embodiments, as shown in Figure 2 , 3As shown in Figures 5 and 6, the column connecting plate 2 includes two first semi-ring connecting plates 21, which are spliced ​​together to form a ring-shaped column connecting plate 2 for fitting onto the wooden column; the beam connecting plate 3 includes two second semi-ring connecting plates 31, which are spliced ​​together to form a ring-shaped beam connecting plate 3 for fitting onto the wooden beam. This arrangement fixes the column connecting plate 2 and the beam connecting plate 3 to the wooden column and beam in a manner similar to a clamp, preventing damage to the load-bearing cross-section of the wooden components and thus affecting their load-bearing performance and service life.

[0038] To prevent damage to the wooden pillars and beams caused by the first connecting section 111 and the third connecting section 113 of the L-shaped plate 11 during deformation, in some embodiments, such as Figures 2 to 4 As shown, the connecting assembly 1 also includes two pads 13, one of which is located on the side of the column connecting plate 2 facing away from the first connecting segment 111, and the other pad 13 is located on the side of the beam connecting plate 3 facing away from the third connecting segment 113. With this arrangement, when the first connecting segment 111 and the third connecting segment 113 of the L-shaped plate 11 deform, they will respectively abut against the two pads 13, thereby protecting the wooden column and the wooden beam.

[0039] In some embodiments, such as Figure 2 , 3 As shown in Figures 5 and 6, the column connecting plate 2 has a first clamping groove 22 into which one end of the connecting assembly 1 extends for connection, and the beam connecting plate 3 has a second clamping groove 32 into which the other end of the connecting assembly 1 extends for connection. One inner wall of the first clamping groove 22 is bolted to one of the friction plates 12, and one inner wall of the second clamping groove 32 is bolted to the other friction plate 12. With this configuration, when the bolt deforms and undergoes the second stage of energy dissipation, the clamping grooves hold the friction plates 12, resulting in significant friction between the friction plates 12 and the inner walls of the first and second clamping grooves 22 and 32. This friction prevents the bolt from deforming, thereby improving the energy dissipation capacity of the bolt deformation.

[0040] Furthermore, in some embodiments, such as Figure 2 , 3 As shown in Figures 5 and 6, four friction plates 12 are provided. The two inner sidewalls of the first clamping groove 22 are respectively connected to two of the friction plates 12 by bolts, and the two inner sidewalls of the second clamping groove 32 are respectively connected to the other two friction plates 12 by bolts. This arrangement increases the number of friction plates 12, thereby increasing the contact area between the friction plates 12 and the inner walls of each clamping groove, thus increasing the friction force and improving the energy dissipation capacity of the bolt deformation.

[0041] In some embodiments, as shown in Figure 4 two friction plates 12 are connected by a reinforcing plate 14. In this way, the structural strength between the L-shaped plate 11 and the two friction plates 12 is improved by the reinforcing plate 14, and the L-shaped plate 11, the friction plate 12 and the reinforcing plate 14 form an integral whole, which can share the force received by each other, thereby improving the energy dissipation capacity.

[0042] Further, in some embodiments, as shown in Figure 4 the reinforcing plate 14 is provided with a plurality of reinforcing plates 14, the plurality of reinforcing plates 14 near the first connecting section 111 are arranged along the length direction of the first connecting section 111, and the plurality of reinforcing plates 14 near the second connecting section 112 are arranged along the length direction of the second connecting section 112. By connecting the two friction plates 12 arranged oppositely by the plurality of reinforcing plates 14, the structural strength is further improved, thereby improving the energy dissipation capacity.

[0043] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
