Description

Technical Field

[0001] This utility model relates to the technical field of toolbox surface polishing equipment, and in particular to a device for the repair and reinforcement of ancient buildings. Background Technology

[0002] In the restoration and reinforcement of ancient buildings, traditional support devices often face the challenge of balancing structural stability and adaptability. For the reinforcement of curved structures such as cylindrical beams and columns, early methods often involved temporary wooden wedges or metal clamps for fixation. The former carries the risk of secondary damage due to uneven stress, while the latter, due to its fixed dimensions, is difficult to adapt to components of different diameters. To address the issue of the versatility of clamp devices;

[0003] While existing technologies include structures that connect segmented curved plates with bolts, assembly is time-consuming and the rigidity of the joints is insufficient, making them prone to deformation and displacement during long-term load-bearing. A more significant problem is that conventional support systems are mostly rigid triangular frames. While they can provide foundation bearing capacity, they cannot achieve synchronous fine-tuning of the clamp components during construction, resulting in stress gaps between the clamps and the column, directly affecting the reinforcement effect. Summary of the Invention

[0004] The purpose of this invention is to provide a device for the repair and reinforcement of ancient buildings, which can support ancient buildings.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a device for repairing and reinforcing ancient buildings, comprising two symmetrically arranged semi-circular clamps.

[0006] The main support rod is connected to the outer circumference of the clamp via a hinge shaft, and the other end of the main support rod is hinged to the grounding base.

[0007] One end of the auxiliary support rod is hinged to the middle of the main support rod, and the other end of the auxiliary support rod is movably connected to the grounding base; the fastening mechanism is located at the end of the auxiliary support rod, which locks the auxiliary support rod and the grounding base to form a triangular support system.

[0008] Preferably, a detachable expansion module is provided between the two semi-circular clamps, and the two ends of the module are connected to the clamps to adapt to structures of different diameters.

[0009] As a preferred option, the expansion module is equipped with a guide pin, and the clamp has a corresponding pin positioning groove to form a module assembly reference.

[0010] Preferably, the clamp is equipped with a rotating fastening bolt, which penetrates the side wall of the clamp and forms a threaded locking structure with the expansion module.

[0011] Preferably, a clamping block is provided between the two clamps, and an adjusting screw is threadedly connected to the inner side of the clamp. The adjusting screw rotates in coordination with the clamping block, and an anti-rotation telescopic rod is simultaneously configured to connect the clamping block and the clamp.

[0012] Preferably, the clamping block is detachably mounted with a buffer bracket, the contact surface of which is covered with an elastic protective layer.

[0013] Preferably, the surface of the elastic protective layer has cross-distributed anti-slip ridges.

[0014] Preferably, the fastening mechanism includes a sliding base plate and a locking bolt. The sliding base plate is hinged to the auxiliary support rod. The sliding base plate moves in the guide rail groove of the grounding base by means of rollers. After it is in place, the locking bolt passes through the threaded hole of the grounding base to fix it.

[0015] Preferably, the bottom surface of the base is provided with a guide rail, and the bottom of the sliding base plate is equipped with a guide wheel assembly that cooperates with the guide rail.

[0016] The beneficial effects of this utility model compared with the prior art are as follows:

[0017] The triangular support system composed of main and auxiliary struts breaks through the limitations of traditional rigid frames. The hinged connection between the main strut and the clamp allows the support angle to be adaptively adjusted, maintaining overall rigidity while automatically compensating for slight tilting of the column. The fastening mechanism at the end of the auxiliary strut forms a dynamic locking mechanism, which can lock the support state in sections during construction and gradually load the overall support force through loosening and tightening, effectively avoiding stress abrupt changes caused by traditional rigid supports.

[0018] The expansion module is quickly pre-positioned via a pin slot, and a rotating bolt with a threaded engagement surface screws into the module's pre-drilled hole, forming a multi-directional constrained rigid connection that completely solves the gap problem in split-type clamps. An innovative design, where an adjusting screw drives the clamping block to advance axially along the anti-rotation telescopic rod, allows the three-point contact clamping mechanism to extend and retract synchronously and equidistantly, eliminating localized stress concentration caused by single-point pressure. The composite elastic protective layer on the clamping block surface forms a flexible engagement interface through cross-ribbed textures, increasing the friction coefficient to prevent slippage and absorbing vibration energy through elastic deformation, making it particularly suitable for protecting historical building components with carved textures on their surfaces.

[0019] The entire device achieves millimeter-level precise adjustment of its position through the rolling of rollers within guide rail grooves. The linkage design between the sliding base plate and the guide wheel assembly enables smooth movement of the heavy-duty support device. Combined with the quick-locking function of the locking bolts, it allows for immediate locking after fine-tuning of support points in confined spaces, significantly reducing positioning errors caused by repeated disassembly and reassembly of traditional devices. This integrated mechanical system achieves highly stable support while also considering construction adaptability and the needs of cultural relic protection, providing reliable technical support for ancient building restoration projects.

[0027] like Figures 1 to 2 Example 1:

[0028] A device for repairing and reinforcing ancient buildings includes two symmetrically arranged semi-circular clamps 1.

[0029] The main support rod 2 is connected to the outer circumference of the clamp via a hinge shaft. The other end of the main support rod 2 is hinged to the grounding base 3 to support the semi-circular clamp 1. One end of the auxiliary support rod 4 is hinged to the middle of the main support rod 2, and the other end of the auxiliary support rod 4 is movably connected to the grounding base 3. The fastening mechanism 5 is located at the end of the auxiliary support rod 4, locking the auxiliary support rod 4 and the grounding base 3 to form a triangular support system. Through the triangular support system, the support effect of the semi-circular clamp 1 on the ancient building is increased. The fastening mechanism 5 includes a sliding base plate 19 and a locking bolt 20. The sliding base plate 19 is hinged to the auxiliary support rod 4. The sliding base plate 19 moves in the guide groove of the grounding base 3 via rollers. After it is in place, the locking bolt 20 is inserted into the threaded hole of the grounding base 3 for fixation. By sliding the sliding base plate 19 on the guide groove and being threadedly connected to the threaded hole by the fastening bolt, the auxiliary support rod 4 can be fixed, thereby forming a triangular support system and further improving the fixing and support effect of the clamp.

[0030] Specifically, a detachable expansion module 6 is provided between the two semi-circular clamps 1. The two ends of the module are connected to the clamps to adapt to structures of different diameters. The expansion module 6 is provided with a guide pin 7, and the clamps have corresponding pin positioning grooves 8 to form a module assembly reference. The clamps are provided with a rotating fastening bolt 9, which penetrates the side wall of the clamps and forms a threaded locking structure with the expansion module 6. It is inserted into the pin positioning groove 8 through the guide pin 7 and then fixed to the clamps by the fastening bolt, thereby realizing the expansion of the distance between the clamps.

[0031] Specifically, the base has a guide rail 17 on its bottom surface, and the bottom of the sliding base plate 19 is equipped with a guide wheel assembly 18 that cooperates with the guide rail 17, so as to facilitate the sliding of the sliding base plate 19 by personnel.

[0032] Example 2: A clamping block 10 is provided between the two clamps. An adjusting screw 11 is threadedly connected to the inner side of the clamp. The adjusting screw 11 rotates with the clamping block 10. An anti-rotation telescopic rod 12 is simultaneously configured to connect the clamping block 10 and the clamp. A buffer bracket 14 is detachably installed on the clamping block 10. The contact surface of the buffer bracket 14 is covered with an elastic protective layer 15. The surface of the elastic protective layer 15 is provided with cross-distributed anti-slip ribs 16. The rotation of the screw drives the clamping block 10 to move, and the moving block drives the buffer bracket 14 to contact the ancient building, thereby fixing the ancient building and further improving the fixing effect of the ancient building. The elastic protective layer 15 is used to prevent the ancient building from being scratched.

[0033] The working principle is as follows: During installation, two semi-circular clamps 1 surround the ancient building column. The connection point is formed by the expansion module 6 or the clamping block 10 to form a dynamic adjustment system. For structures of different diameters, the expansion module 6 can be pre-positioned with the pin positioning groove 8 of the clamp through the guide pin 7, and the fastening bolt 9 can be rotated to make the module and the clamp form a rigid connection; or the clamping block 10 system can be used. The adjusting screws 11 arranged symmetrically on both sides are rotated to push the clamping block 10 to move radially. The anti-rotation telescopic rod 12 keeps the clamping block 10 stable in posture during the displacement. During the adjustment, the elastic protective layer 15 of the buffer bracket 14 is in contact with the surface of the ancient building in advance. The cross anti-slip ribs 16 produce micro-deformation under pressure, which increases the friction and avoids hard scratches.

[0034] In the support system, the main support rod 2 forms a variable-angle support surface through the hinge point with the clamp, and the auxiliary support rod 4 is hinged to the middle of the main support rod 2 to form a composite lever structure. When the sliding base plate 19 moves along the guide rail groove of the grounding base 3, it drives the auxiliary support rod 4 to change the angle with the main support rod 2 in sync. At this time, the support tilt angle of the main support rod 2 is adaptively adjusted to form a dynamic balance. After the optimal support position is determined, the locking bolt 20 passes through the threaded hole of the sliding base plate 19 and the guide rail groove to complete the positioning, so that the main and auxiliary support rods 4 form a stable triangular support truss. The truss decomposes the load borne by the clamp into vertical pressure and horizontal constraint force through the force transmission of the hinge point, which not only ensures the stability of the structure, but also avoids local stress concentration.

[0035] During the adjustment process, the radial expansion system of the clamp and the axial adjustment system of the support rod work together: when the expansion module 6 extends the circumference of the clamp, the main and auxiliary support rods 4 automatically compensate for the support angle offset caused by the change in length; when the clamping block 10 system performs fine-tuning, the elastic deformation of the buffer bracket 14 can absorb vibration energy, and the meshing of the anti-slip ridge 16 with the surface of the ancient building enhances the anti-slip ability. The whole device achieves customized adaptation of the irregular structure of traditional buildings through modular combination, and constructs a multi-layer protection system while maintaining the original architectural style, ultimately forming a three-dimensional protection network composed of an inner flexible buffer, a middle rigid constraint, and an outer triangular support.

[0036] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
