Description

Technical Field

[0001] The utility model relates to a reinforcement device for protecting ancient buildings, belonging to the field of ancient building protection. Background Art

[0002] Ancient buildings are the memory of a city and witnesses of its history. They carry the cultural heritage of the city. Once damaged, the cultural relics themselves and the historical and cultural information they carry will no longer exist. Therefore, the protection of ancient buildings is a very important task.

[0003] Among the ancient building protection projects, one of them is the reinforcement and protection of beams. For example, the Chinese utility model patent with authorization announcement number CN209053457U discloses an ancient building reinforcement device, including an upper fastening ring, a lower fastening ring and a plurality of adjustable brackets arranged between the upper and lower fastening rings and distributed along the circumferential direction. The adjustable bracket includes an upper support rod hinged to the upper fastening ring at the upper end, a lower support rod hinged to the lower fastening ring at the lower end, and an intermediate hinge shaft for hingedly connecting the lower end of the upper support rod to the upper end of the lower support rod, and the intermediate hinge shaft is provided with a locking nut for locking the upper support rod and the lower support rod so as to fix the angle between the upper support rod and the lower support rod.

[0004] When the reinforcement protection is in use, the upper fastening ring and the lower fastening ring are respectively fixed on both sides of the position to be reinforced, and then the upper support rod and the lower support rod are compressed so that the adjustable bracket generates a supporting force on the upper fastening ring and the lower fastening ring. At the same time, the locking nut is adjusted to fix the angle between the upper support rod and the lower support rod and form a stable support for the upper fastening ring and the lower fastening ring. Since the angle between the upper support rod and the lower support rod can be adjusted to adapt to the shape, the angles of multiple adjustable brackets can be adjusted independently, so that curved beams with different curvatures can be reinforced. It has good versatility, simple structure, low cost and easy operation.

[0005] However, there are still the following problems:

[0006] 1: When the upper support rod and the lower support rod generate supporting force on the upper fastening ring and the lower fastening ring and fix the angle between the two support rods, the two support rods are compressed and the locking nuts are adjusted at the same time, that is, they are compressed and adjusted at the same time. This method often requires workers to work with both hands at the same time. Therefore, when reinforcing aerial components such as curved beams, especially when reinforcing curved beams while standing on a simple ladder, the operation is inconvenient and there are even great safety hazards during installation.

[0027] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0028] Example: Figure 1-2 As shown, a reinforcement device for ancient building protection is suitable for reinforcing a curved beam 0, and as in the prior art, comprises a fastening ring 1, a fastening ring 2, and a plurality of adjustable brackets 3 arranged between the fastening ring 1 and the fastening ring 2 and distributed circumferentially;

[0029] The fastening ring 1 and the fastening ring 2 can be seen as follows Figure 5 As shown, they all include a semicircular ring 11 and a semicircular ring 12, one end of the semicircular ring 11 is hinged to one end of the semicircular ring 12, and the other end of the semicircular ring 11 is locked to the other end of the semicircular ring 12 by fastening bolts;

[0030] The adjustable bracket 3 includes a support rod 1 31 having one end hinged to the fastening ring 1 1 , a support rod 2 32 having one end hinged to the fastening ring 2 2 , and the other end of the support rod 1 31 is hinged to the other end of the support rod 2 32 .

[0031] Different from the prior art, this embodiment further includes a tightening structure 4, which includes a support rod three 41, a tightening nut 42, and a fulcrum block 43, wherein the support rod three 41 and the support rod one 31 are hinged and have a threaded segment 411, the fulcrum block 43 is hinged on the support rod two 32 and allows the threaded segment 411 to pass through, the fulcrum block 43 is provided with a through hole 431 for the threaded segment 411 to pass through, the hinge center axis of the fulcrum block 43 is parallel to the hinge center axis of the support rod three 41, and the tightening nut 42 is used to cooperate with the threaded segment 411.

[0032] When the reinforcement device is in use, first, the fastening ring 1 and the fastening ring 2 are fixed on both sides of the position of the curved beam to be reinforced, and then, under the premise that the threaded section 411 passes through the fulcrum block 43, the position of the fastening nut 42 on the threaded section 411 is changed by rotating the fastening nut 42, so that the fastening nut 42 presses against the fulcrum block 43, thereby expanding and tightening the angle between the support rod 1 31 and the support rod 2 32, so that the support rod 1 31 and the support rod 2 32 respectively generate a stable supporting force for the fastening ring 1 and the fastening ring 2 2, and at the same time, when the fastening nut 42 presses against the fulcrum block 43, the angle between the support rod 1 31 and the support rod 2 32 is fixed.

[0033] It can be seen that the reinforcement device, while making the support rod 1 31 and the support rod 2 32 generate a supporting force on the fastening ring 1 and the fastening ring 2 2 and fixing the angle between the support rod 1 31 and the support rod 2 32, only needs to rotate the tightening nut 42. This action does not require the use of both hands at the same time, is simple and convenient, and is safer when working in the air, especially when standing on a simple ladder.

[0034] The support rod 3 41 also includes a bare rod section 412 hinged to the support rod 1 31 and connected to the threaded section 411. Before the fastening ring 1 1 and the fastening ring 2 2 are respectively fixed to the positions of the curved beam to be reinforced, the tightening nut 42 is pre-set on the bare rod section 412. When the fastening ring 1 1 and the fastening ring 2 2 need to be respectively fixed to the positions of the curved beam to be reinforced, the angle relationship between the fastening ring 1 1 and the fastening ring 2 2 must first be changed or adjusted. During this process, each bare rod section 412 allows the corresponding tightening nut 42 to slide freely thereon, thereby ensuring that the fastening ring 1 1 and the fastening ring 2 2 are easy to install. If the support rod 3 41 only has the threaded section 411, the operator needs to manually adjust the position of each tightening nut 42 when adjusting the angle relationship between the fastening ring 1 1 and the fastening ring 2 2, which makes the installation complicated.

[0035] In the embodiment, the threaded section 411 extends to the free end of the support rod 41. Figure 3 As shown, the threaded section 411 is also provided with an outer top nut 44 which tightens the other side of the fulcrum block 43 to further enhance the stability of the entire adjustable bracket.

[0036] In the embodiment, the lengths of the support rod 1 31 and the support rod 2 32 are equal, the support rod 3 41 is hinged at the middle position of the support rod 1 31 , and the fulcrum block 43 is arranged at the middle position of the support rod 2 32 .

[0037] In the embodiment, Figure 4 As shown, support rod 1 31 includes hinged ear 1 311 connected to support rod 2 32, support rod 2 32 includes hinged ear 2 321 connected to support rod 1 31, hinged ear 1 311 and hinged ear 2 321 are both connected to the same hinge shaft 6, an internal threaded hole is provided on the circumferential surface of the hinge shaft 6, support rod 4 5 is screwed into the internal threaded hole, support rod 4 5 is further reinforced on the curved beam at the position between fastening ring 1 1 and fastening ring 2 2, so as to enhance the reinforcement effect of the whole reinforcement device, and when designing the hinge shaft 6, it is intended to use a material with higher strength as much as possible.

[0038] The support rod three 41 is provided with a clearance hole 413 for the support rod four 5 to pass through. The clearance hole 413 is as large as possible so that the clearance hole 413 does not contact the support rod four 5. At this time, the support rod three 41 does not play any supporting role on the support rod four 5. The support force of the support rod four 5 is purely provided by the hinge shaft 6. The support rod four 5 does not affect the support of the support rod three 41. Therefore, the force of the entire adjustable bracket 3 is more dispersed and reasonable.

[0039] The above embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary persons in the art to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
