Description

Technical Field

[0001] The invention relates to the technical field of building structures, and in particular to a device for enhancing the earthquake resistance of a bracket structure of an ancient building. Background Art

[0002] As an important part of cultural heritage, the unique architectural style and historical value of ancient buildings make protection and restoration work particularly important. In ancient buildings, the bracket structure, as a traditional wooden support system, not only supports the weight of the roof and disperses external forces, but also has significant decorative and artistic value. However, since most of these buildings were built hundreds of years ago, with the passage of time, the aging of materials, loosening of structures, and the impact of natural disasters such as earthquakes, the seismic performance of ancient buildings is generally poor. Especially when encountering strong earthquakes, structural deformation or even collapse is prone to occur, which seriously threatens the safety of ancient buildings.

[0003] At present, the protection and restoration technology of ancient buildings is mainly focused on restoring the original appearance and delaying aging, but there is still a lack of effective and feasible solutions for how to enhance the seismic performance of ancient buildings when facing external forces such as earthquakes. Traditional seismic resistance methods usually cause great interference to the original structure of ancient buildings, making it difficult to improve their seismic resistance without destroying their cultural value.

[0004] As an important supporting and decorative structure of ancient buildings, although the bracket has a certain stability in structure, its unique structural form also makes it easy to become unstable or displaced under dynamic loads such as earthquakes. Especially when modern building materials and technologies cannot be applied to traditional structures, how to enhance the seismic performance of the bracket without changing the original architectural style and structure has become a technical problem that needs to be solved urgently in the field of ancient building protection. To this end, we propose a device to enhance the seismic performance of the bracket structure of ancient buildings. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] See also Figure 1-Figure 6 As shown, the present invention is a device for enhancing the seismic performance of the bracket structure of an ancient building, comprising

[0033] A fixing assembly, wherein several groups of the fixing assembly are used to clamp and limit the plurality of bars on the bracket respectively, and the fixing assembly comprises a groove frame plate 1;

[0034] A rotating member, the rotating member comprises a mounting plate 2, the mounting plate 2 is detachably connected to the groove frame plate 1;

[0035] Among them, the outer side of the groove frame plate 1 is movably connected with two groups of tie assemblies through two groups of rotating parts, and the tie assemblies include a pull rod 3 and a connecting tube 4. One end of the pull rod 3 and the connecting tube 4 are respectively connected to the outer sides of the adjacent groove frame plate 1 through rotating parts, and the other end of the pull rod 3 is slidably set inside the cavity of the connecting tube 4. The other end of the connecting tube 4 is fixedly connected with an external threaded ring 5, and the outer wall of the external threaded ring 5 is provided with a plurality of notches in a circular array. The external threaded ring 5 is threadedly connected with an internal threaded ring 6.

[0036] The inner diameter of the inner thread ring 6 is larger than the outer diameter of the pull rod 3 .

[0037] The bracket itself is a typical wooden structure, which is supported by splicing and overlapping wood. The bracket consists of multiple wooden components (such as bracket blocks, arch bars, purlins, etc.) connected by mortise and tenon joints. Although the structure is flexible, it is not completely tight. This loose connection method makes it easy for wooden components to shift or fall off when encountering dynamic loads such as earthquakes, resulting in structural instability and poor earthquake resistance. Therefore, it is necessary to enhance the earthquake resistance of the bracket structure through this structural device.

[0038] As can be seen from the above, the wooden structure rods on the bracket structure are clamped and fixed by a number of fixing components, and a plurality of small units are formed. Further, they are tied by the set tie components. After two adjacent small units are formed, the staff uses the characteristic that the other end of the tie rod 3 is slidably set inside the cavity of the connecting tube 4, and then adjusts the length of the tie rod 3. After that, the pipe mouth of the external thread ring 5 is contracted by rotating the internal thread ring 6, and then the position of the tie rod 3 is fixed, and the plurality of small units are further connected to form a whole.

[0046] A rotating ring 10 is fixedly connected to the outer wall of the middle end of the bidirectional screw rod 7 .

[0047] Specifically, the staff drives the bidirectional screw rod 7 to rotate by rotating the rotating ring 10, and further utilizes the characteristics that the bidirectional screw rod 7 is symmetrical and movably connected with two guide blocks 8 on the outside, and the guide blocks 8 are slidably set inside the installation groove, thereby driving the two guide blocks 8 to move relative to each other, and further driving the two clamping blocks 9 to move relative to each other to clamp and fix the bracket structure rod, which is convenient and quick to operate.

The two bearing rods 12 are symmetrically and fixedly installed on both ends of the bidirectional screw 7. One end of the bearing rod 12 is rotatably connected to the inner wall of the cartridge seat 11 cavity.

[0049] It can be seen from the above that in order to ensure the stability of the bidirectional screw 7 during rotation, by providing the cartridge seat 11 and the bearing rod 12, the structure operates more stably during the specific process of rotating the bidirectional screw 7 to clamp the component rod.

[0056] The inner diameters of the first opening and the second opening are both larger than the outer diameter of the fixing bolt 14 .

[0057] As can be seen from the above, by disassembling and connecting the mounting plate 2 and the groove frame plate 1, it is convenient for personnel to install a suitable number of tie assemblies according to the number of component rods of the bracket, strengthen the overall connectivity of the bracket component rods, and further enhance the earthquake resistance of the bracket.
