Technical Field

[0001] This utility model relates to the field of wall crack repair structure technology, and in particular to a fishbone chain assembly for repairing cracks in rammed earth walls. Background Technology

[0002] Rammed earth walls, as a traditional building form, have a long history worldwide. However, they are prone to cracking during long-term use. Currently, the existing technology for repairing cracks is a prefabricated wall crack repair mechanism with patent number CN221346416U. However, according to the document, this patent is mainly applicable to concrete or brick walls. When used on rammed earth walls, the rammed earth walls cannot withstand the expansion force of the expansion bolts and do not have a structure to reinforce the cracks. Therefore, we propose a fishbone chain assembly for repairing cracks in rammed earth walls. Utility Model Content

[0003] The main objective of this invention is to provide a fishbone chain assembly for repairing cracks in rammed earth walls, which can effectively solve the problems in the background art.

[0008] Preferably, the small anchor structure and the large anchor structure are identical in structure, and the model of the small anchor structure is smaller than that of the large anchor structure.

[0009] Preferably, the length of the metal strand is between 1 and 1.5 meters, the length of the thick chain is set according to the length of the crack, and the large fixing ring on the thick chain is provided every 25 centimeters. The thick chain is a flexible structure that can be arranged along the curved gap.

[0010] Preferably, the small anchor structure is used to pass through the small fixing ring and be fixed in a pre-set fixing hole in the wall, and the small anchor structure is used to pass through the large fixing ring on the metal strand and the large fixing ring on the thick chain that overlaps with it and be fixed in the crack.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-5As shown, a fishbone chain assembly for repairing cracks in rammed earth walls includes a thick chain 1 installed along the crack, a large fixing ring 2 connected to the thick chain 1 for fixing to the crack, a metal wire 3 installed along the surface of the thick chain 1, small fixing rings 4 connected to both ends of the metal wire 3 for fixing to the wall, a large fixing ring 2 also connected to the middle of the metal wire 3, a large anchor structure 5 inserted in the large fixing ring 2, and a small anchor structure 6 inserted in the small fixing ring 4.

[0021] The large anchor structure 5 includes a frustum rod 51, a fiber cap 53 installed at the end of the frustum rod 51, and an anchor spike 52 connected to the arc surface of the frustum rod 51.

[0022] Specifically, the anchor spikes 52 arranged continuously on the truncated cone rod 51 of the large anchor structure 5 form a strip-shaped component similar to a fishbone through the flexible truncated cone rod 51, which has good conformability and embedding force. This component can be inserted along the crack direction of the rammed earth wall and form multi-point anchoring and bridging effect inside the crack, thereby improving the local structural stability of the wall.

[0023] The anchor 52 and the frustum rod 51 are arranged at an angle of 30 to 60 degrees, and there are multiple anchor 52s;

[0024] Specifically, the angle is set so that after the structure is inserted into the gap or crack, it forms an effective unidirectional anchoring force to prevent the component from slipping back or loosening.

[0025] The structures of small anchor structure 6 and large anchor structure 5 are the same, but the model of small anchor structure 6 is smaller than that of large anchor structure 5.

[0026] Specifically, since the small anchor structure 6 and the large anchor structure 5 have the same structure but different sizes, the small anchor structure 6 also includes structures such as the frustum rod 51, anchor spikes 52, and fiber caps 53. The cross-section of the frustum rod 51 on the small anchor structure 6 is usually wedge-shaped, with a slightly pointed front end for easy insertion and a gradually widening rear end to form a natural limiting trend. Multiple anchor spikes 52 are symmetrically arranged on both sides of the frustum rod 51 along the length direction. Each anchor spike 52 is arranged at an angle of 30 to 60 degrees with the frustum rod 51 and has a barb-shaped structure at the end. During insertion, it can penetrate into the adobe or rammed earth material on both sides of the crack to form an effective unidirectional anchoring force and prevent the component from slipping or loosening.

[0027] The length of the metal strand 3 ranges from 1 to 1.5 meters, the length of the thick chain 1 is set according to the length of the crack, and there is a large fixing ring 2 on the thick chain 1 every 25 centimeters. The thick chain 1 is a flexible structure that can be arranged along the curved gap.

[0028] Specifically, the thick chain 1 is a flexible metal structure, with horizontally arranged metal strands 3 connected to each of its large fixed rings, forming a sturdy structure similar to a fish skeleton, which improves the stability of the wall after repair. The length of the metal strands 3 is selected according to the length of the crack.

[0029] The small anchor structure 6 is used to pass through the small fixing ring 4 and fix it in the pre-set fixing hole in the wall. The small anchor structure 6 is also used to pass through the large fixing ring 2 on the metal wire 3 and the large fixing ring 2 on the thick chain 1 that overlaps with it and fix it in the crack.

[0030] Specifically, when the small anchor structure 6 is installed on both sides of the crack, it penetrates into the adobe or rammed earth material on both sides of the crack to form an effective unidirectional anchoring force, preventing the component from slipping back or loosening. Similarly, the large anchor structure 5 has a large structure size. This structure forms an effective unidirectional anchoring force by inserting it into the crack to fix and tighten the two large fixing rings 2 that overlap, preventing the component from slipping back or loosening. At the same time, the fiber cap 53 acts as a limit to prevent it from sliding into the depth of the wall due to gravity or changes in the wall, and serves as a base point for subsequent plastering.

[0031] It should be noted that this utility model is a fishbone chain assembly for repairing cracks in rammed earth walls. During installation, a thick chain 1 is arranged along the direction of the crack. At the same time, the large fixing rings 2 on the metal strands 3 are overlapped with the large fixing rings 2 on the thick chain 1. Then, the tip of the large anchor structure 5 is inserted into the two large fixing rings 2 and driven into the crack with a tool. Multiple metal strands 3 are fixed to the thick chain 1 in sequence. Then, small anchor structures 6 are inserted into the small fixing rings 4 at both ends of the metal strands 3. The metal strands 3 are stretched straight and the small anchor structures 6 are driven into the wall for anchoring. In this way, the ends of multiple metal strands 3 can be fixed to the rammed earth wall, thereby reinforcing the cracks in the wall through this fishbone-like structure frame.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
