Embodiment 1

[0068] The invention relates to a reinforcing member of a wooden structure of an ancient dwelling, which is used for reinforcing the joints connecting a wooden column 1 and a wooden beam 2 in the wooden structure of an ancient dwelling. Such as Figure 1-3 As shown, the reinforcing member includes a connecting seat 4 and a connecting plate 5 . The connecting plate 5 is fixed on the side surface of the wooden beam 2 by the wooden beam fixing part 7 . The connection base 4 includes a cylinder portion and a support connection portion. The cylinder part is composed of two or more shell units that surround the wooden column 1 and are spliced ​​together, and are fixed on the side of the wooden column 1 by more than two wooden column fixing parts 6 . The outer surface of the shell unit where the cylindrical part is adjacent to the wooden beam 2 is provided with a support connection part.

[0069] Such as Figure 4 , Figure 5 As shown, the support connecting portion includes two...

Embodiment 2

[0074] Such as figure 1 Shown, a kind of reinforcement member of wooden structure of ancient dwellings, its structure is the same as in embodiment one. On this basis, an elastic clip 8 is set in the area surrounded by the first plug board 42, the second plug board 43, the left connection board 51, and the right connection board 52 to prevent the left connection board 51 and the right connection board 52 from Under the action of external force, move up and pull out from the connecting seat 4. Moreover, the arrangement of the elastic clips 8 can also absorb the energy at the joints, which is beneficial to improve the seismic performance of the wooden structure.

Embodiment 3

[0076] An ancient residential wooden structure reinforcing member, the structure of which is the same as that of Embodiment 1 or Embodiment 2. Such as Figure 9 As shown, an elastic piece 10 is provided on the connecting plate 5 . The elastic piece 10 is located in the middle of the longitudinal connection between the second end of the first guide bar 9a and the second end of the third guide bar 9c on the connecting plate 5; The middle part of the longitudinal connection line of the second end of the four guide strips 9d. After the connection plate 5 penetrates into the first plug-in board 42 and the second plug-in board 43 of the connection seat 4 , the elastic piece 10 is ejected from the connection plate 5 to prevent the connection plate 5 from being pulled out from the connection seat 4 .

Abstract

The invention provides a member for reinforcing wood structures of ancient dwellings. The member comprises a connecting seat and connecting plates. The connecting plates are fixed to the side surfaces of a wood beam; the connecting seat comprises a barrel and a support connecting portion; more than two shell units fixedly encircle the side surfaces of a wood column to form the barrel; the support connecting portion is arranged on the outer surfaces of the shell units, which are adjacent to the wood beam, of the barrel and comprises two side plates, a first insertion plate and a second insertion plate, and insertion slots which are aligned with one another are formed in the first insertion plate and the second insertion plate. Positioning grooves are formed in the insertion slots; the connecting plates can be guided by guide strips on the connecting plates to sequentially penetrate the insertion slots of the first insertion plate and the second insertion plate and can be sunken to the bottoms of the insertion slots under the effect of the gravity, and the guide strips are staggered from the positioning grooves to form clamp strips, so that the connecting plates can be prevented from being pulled out of the connecting seat. The member has the advantages that the beam and the column can be connected with each other in a semi-rigid manner, and the member is good in energy dissipation performance under the effects of earthquake and wind load; a method for reinforcing the wood structures by the aid of the member is easy to implement, and the wood structures rarely can be damaged.

Description

technical field [0001] The invention relates to the field of building structure reinforcement, in particular to an ancient residential wooden structure reinforcement component and a reinforcement method thereof. Background technique [0002] Most of the ancient Chinese dwellings are load-bearing wooden structures. Ancient dwellings are an important manifestation of historical and cultural development. Compared with palaces and ancestral temple buildings, the protection status of ancient dwellings is worrying. Part of the reason is that the wooden components in ancient dwellings are rarely protected with "one-step four-ash" or painted outer layers, and the ability of wooden structures to resist aging and various damages is relatively poor. In addition, under the action of long-term loads, the performance of the wood itself declines more obviously, which eventually leads to different types of damage. Common damage types of wooden structures include: cracking, decay, deformat...
