Description

Technical Field

[0001] This utility model relates to a repair structure, and more particularly to an in-situ pier-joint repair structure for ancient wooden buildings, belonging to the field of ancient building repair technology. Background Technology

[0002] Ancient buildings refer to structures left over from history that possess unique artistic styles and historical value. They typically employ a timber structure as their main component, consisting of a timber frame system composed of columns, beams, purlins, and other wooden elements, with walls primarily serving an enclosure and providing insulation. However, ancient buildings are susceptible to damage from natural and human factors such as decay, insect infestation, and fire. To protect these precious cultural heritages, ancient building restoration techniques have emerged. Ancient building restoration requires advanced skills and extensive experience to ensure that the restored structure not only retains its original appearance but also withstands future damage risks.

[0003] In existing in-situ pier-joint repair processes, the repair section is fixed to the original column structure by adhesive bonding, which results in poor connection stability. Furthermore, when the original column structure is heated and expands, the repair section cannot expand uniformly due to the different coefficients of thermal expansion, leading to separation between the two. Therefore, an in-situ pier-joint repair structure for ancient wooden buildings is proposed. Utility Model Content

[0004] In view of this, the present invention provides an in-situ pier-joint repair structure for ancient wooden buildings, in order to solve or alleviate one of the technical problems existing in the prior art, and at least provide a beneficial option.

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1-5 As shown, this utility model embodiment provides an in-situ pier joint repair structure for ancient wooden buildings, including a repair component 20. The repair component 20 includes a shape memory alloy gasket 22, a first repair section 23, a tenon 24, a first pad 25, a first connecting block 26, a second pad 27, a second connecting block 28, a slot 29, a locking block 210, a second repair section 211, a mortise 212, and a micro-damage detection probe 213.

[0030] The bottom of the shape memory alloy gasket 22 is provided with a first repair section 23, and a tenon 24 is fixedly connected to the bottom of the first repair section 23.

Finally, the locking block 210 is inserted into the slot 29, and the reversible repair layer 215 and the external antique paint are applied to complete the installation of the repair structure. ， After the locking block 210 is inserted into the slots 29 on the first connecting block 26, the second connecting block 28 and the tenon 24 in sequence, the first connecting block 26, the second connecting block 28 and the tenon 24 can be combined together. Through the limiting effect of the locking block 210 and the tenon 24, the first connecting block 26, the second connecting block 28 and the tenon 24 are prevented from moving radially. After the reversible repair layer 215 is constructed, the position of the locking block 210 is reinforced, and the stability of the connection part is further improved.
