[0002] In cultural relic protection engineering, purlin component is the important component of ancient building, bears the weight of building structure, and is the key to maintain the stability of the whole building. Therefore, the protection and repair work of purlin component has extremely important significance for maintaining the integrity and historical features of ancient building. Especially in those buildings with high historical and artistic value, purlin component not only bears the structure function, but also records the cultural background and social features of that time with the inestimable cultural value.

[0003] Purlin component is easily affected by weathering, insect damage and other factors due to long-term exposure to natural environment, which causes the rotten phenomenon of wooden material and affects the structural strength.

This requires that the repair work must consider the needs of structural safety and cultural preservation.

[0004] Although the traditional repair method can restore the structural performance of purlin component to some extent, these methods often ignore the protection of painting. For example, when carrying out inlaying treatment, the original painting may be damaged due to the combination mode of new and old materials; and when replacing the component, the historical value of the original component and its painting is completely lost. In addition, these methods may not meet the requirements of modern cultural relic protection for the integrity and authenticity of cultural relics, especially when purlin component is severely rotten and reaches the limit of stress requirement, the traditional reinforcing means often appears to be inadequate.

[0030] The reinforcement device provided by the utility model has advantages in structural strength improvement and protection of color drawing.

[0031] Firstly, in the aspect of structural strength improvement, the telescopic design and locking function of inner support component 1 can flexibly adapt to different sizes of rotten areas, ensuring that the reinforcement device is firmly embedded in the repair groove 11 and providing reliable internal support. The connector design of assembly component 2 ensures the effective connection of purlin 10 and cutting part 12, enhancing the overall stability of the structure.

[0032] Secondly, in the aspect of protecting color drawing, assembly component 2 is reinforced by non-direct contact, avoiding damage to the surface color drawing of purlin 10 and effectively protecting the artistic value of the component surface.

[0033] This design reduces interference with the original color drawing, achieving the dual goals of structural reinforcement and cultural protection.

[0034] As Figures 2-4 shown, inner support component 1 includes sleeve rod 3, sleeve pipe 4 and locking piece 5, sleeve rod 3 is sleeved in sleeve pipe 4, locking piece 5 is installed at the end of sleeve pipe 4, used to lock the relative movement of sleeve rod 3 in sleeve pipe 4.

[0035] The design of inner support component 1 is to deal with the common rotten problem in the repair of ancient building purlin, especially in the case of serious rottenness. Inner support component 1 can effectively support and reinforce the rotten area.

[0036] Among them, locking piece 5 is in the form of a tapered cylinder with threads on the inner wall, sleeve pipe 4 has assembly threads 41 at the end, locking piece 5 is connected to assembly threads 41, and sleeve pipe 4 has a plurality of inwardly tapered grooves 42 circumferentially at assembly threads 41. Handle 51 is installed on locking piece 5.

[0037] Specifically, the relative movement between the sleeve rod 3 and the sleeve pipe 4 of the inner support assembly 1 can be adjusted and fixed by the locking piece 5. The locking piece 5 adopts a conical cylinder structure with internal threads, is installed at the end of the sleeve pipe 4, and is operated by the handle 51 to feed along the assembly thread to realize the fixation between the sleeve rod 3 and the sleeve pipe 4. In addition, the sleeve pipe 4 is provided with an inwardly recessed groove 42 at the assembly thread 41 in the circumferential direction, and when the locking piece 5 is tightened, the inwardly recessed groove 42 is compressed, so that the sleeve rod 3 and the sleeve pipe 4 are tightly matched to provide stable support force.

[0038] The inner support assembly 1 further comprises a support seat 6 installed at the end of the sleeve rod 3 and the sleeve pipe 4. The support seat 6 can increase the contact area between the inner support assembly 1 and the repair groove 11, and ensure that the reinforcing device can uniformly distribute the force to prevent wood damage caused by excessive local pressure. In particular, the support seat 6 is provided with mounting holes, and the support seat 6 can be fastened to the purlin 10 by means of screws to further enhance the assembly stability of the inner support assembly 1 and the purlin 10.

[0039] As shown in Figure 2 , Figure 5 and Figure 6 , the number of assembly components 2 is multiple, and the multiple assembly components 2 are installed on the sleeve rod 3 and / or the sleeve pipe 4. The assembly component 2 comprises a hoop 7 and a connecting piece 9, the hoop 7 is installed on the sleeve rod 3 and / or the sleeve pipe 4, one end of the connecting piece 9 is connected to the hoop 7, and the other end is connected to the cutting part 12.

[0040] Through the design of multiple assembly components 2, the connecting piece 9 can be uniformly distributed on the sleeve rod 3 and the sleeve pipe 4, thereby ensuring that the connection between the reinforcing device and the cutting part 12 is more stable, and avoiding the instability and local stress concentration problem caused by single-point connection. The design of the connecting piece 9 enables the cutting part 12 to be installed without straight surface painting, thereby avoiding direct damage to the original painting during the reinforcing process, and effectively protecting the artistic value of the surface of the component.

[0041] As shown in Figure 6 , the hoop 7 comprises a hoop body 71 and a fastener 73, the hoop body 71 matches the sleeve rod 3 or the sleeve pipe 4, the hoop body 71 is provided with a holding hole 72, the fastener 73 installs the hoop body 71 on the sleeve rod 3 and / or the sleeve pipe 4 through the holding hole 72, the hoop body 71 is provided with a filling hole 74, a friction ring 8 is arranged in the filling hole 74, and the connecting piece 9 is connected to the hoop body 71 through the friction ring 8. The filling hole 74 is specially prepared for the friction ring 8, and the friction ring 8 is placed in this hole to play the role of a transition medium between the connecting piece 9 and the hoop body 71. In this way, the hoop body 71 not only ensures the reliable connection between the reinforcing device and the inner support assembly, but also provides an ideal installation position for the friction ring 8, so that it can play the best role in the reinforcing process.

[0042] AsFigure 7 As shown, the friction ring 8 is a cylindrical structure made of rubber, and the outer wall of the friction ring 8 is provided with a limiting groove 81, and the inner hole of the friction ring 8 is a friction groove 82. The friction ring 8 is made of rubber, which has good elasticity and wear resistance, can provide sufficient friction while reducing wear and absorbing vibration, thereby protecting the reinforcement device and the ancient building component from damage. The design of the friction ring 8 simplifies the installation process of the connecting piece 9, and through the cooperation of the friction groove 82 and the connecting piece 9, the connection strength is guaranteed, and the installation and adjustment on site are facilitated.

[0043] As shown in Figure 5 and Figure 7 , the connecting piece 9 is inserted into the friction groove 82, and the connecting piece 9 is provided with a connecting disc 91 at the end, and the connecting disc 91 is connected with the cutting part 12. The design of the connecting disc 91 increases the connecting surface, ensures the contact area between the reinforcement device and the cutting part, and improves the stability of the connection. In particular, other quick connection structures can also be used between the connecting piece 9 and the cutting part 12, which is not limited here.

[0044] In use, the rotten range is first judged by knocking the purlin 10, then the cutting tool is used to take off the cutting part 12 from the purlin 10, and the rotten parts on the purlin 10 and the cutting part 12 are cleaned, and the cleaned parts form the repair groove 11 on the purlin 10.

[0045] Then, the size of the inner support assembly 1 is adjusted according to the size of the repair groove 11, that is, the relative position of the sleeve rod 3 and the sleeve pipe 4 is adjusted, so that the support seat 6 on the sleeve rod 3 and the sleeve pipe 4 abuts against the inner wall of the repair groove 11, and the relative position relationship between the two is locked by the locking piece 5. Specifically, the handle 51 is the locking piece 5 along the assembly thread 41, and under the conical structure of the locking piece 5, the inner shrinkage groove 42 is compressed, so that the sleeve pipe 4 tightly holds the sleeve rod 3.

[0046] Then, a plurality of assembly assemblies 2 are uniformly installed on the inner support assembly 1. Specifically, the friction ring 8 is inserted into the filling hole 74 of the hoop body 71, and the stable setting of the friction ring 8 in the filling hole 74 of the hoop body 71 can be realized through the limiting groove 81; then the hoop body 71 is fixed on the sleeve rod 3 and / or the sleeve pipe 4 by the fastener 73 (preferably a bolt and a nut), and finally the connecting piece 9 is inserted into the friction groove 82 of the friction ring 8, and the specific insertion depth is not limited at this time.

[0047] Then, the structure of the cutting part 12 is reinforced, that is, the cutting part 12 is trimmed to a regular shape, and the steel plate is glued to the cutting part 12 by epoxy resin.

[0048] Then the cutting part 12 is buckled to the connecting disc 91 of the connecting part 9, and the cutting part 12 is slowly pressed down until the cutting part 12 is attached to the purlin 10. During the process, the connecting part 9 slides in the friction ring 8 until it slides to the target fixed position. After the cutting part 12 is removed, the connecting part 9 and the friction ring 8 are connected by curing glue.

[0049] Then the groove 11 is filled with wood material of the same type as the purlin 10.

[0050] Finally, epoxy resin glue is applied on the purlin 10, the cutting part 12 and the connecting disc 91 to stick the cutting part 12 back to the purlin 10. During the curing process of the epoxy resin glue, iron clamps can be used to clamp the purlin 10 and the cutting part 12. Rock wool cloth can be used as a gasket to avoid injury. After the epoxy resin glue is cured, the gap is processed.

[0051] Those skilled in the art can understand that the above-mentioned embodiments are specific embodiments for implementing the present application, and in actual application, various changes can be made in form and details without departing from the spirit and scope of the present application.
