[0035] The following describes the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0036] See Figures 1-12 The utility model provides a column reinforcement device, which is used to be clamped outside the column and can withstand horizontal force to achieve reinforcement of the column. The reinforcement device includes a chain, a support rod 1 and a locking assembly 4.

The two chains have the same length and include inner chain links 2 and chain plates 3 that are alternately arranged and connected by pins 11; there are multiple support rods 1, which are arranged between the two chains. The length direction of the support rod 1 is parallel to the axis of the pin 11. The upper and lower ends of the support rod 1 are fixedly connected to the pins 11 on the two chains, thereby fixing the support rod between the two chains. When the chain is wrapped (wrapped) around the column, the support rod is also wrapped around the outside of the column; the locking assembly 4 is used to lock and fix the two ends of the chain. The number of the locking assembly 4 is the same as the number of the chains, and they correspond one to one, that is, A locking assembly 4 is used to lock and fix a chain. The locking assembly 4 includes a first hook 41 that can hook the head of the chain and a second hook 42 that can hook the tail of the chain. A connecting part 412 is provided at the tail of the first hook 41 and the second hook 42. A connecting hole is provided on the connecting part 412. The connecting hole is used to install a locking bolt 43 and tighten it through a thread. Specifically, the bolt passes through the two connecting holes in turn and is connected to a nut. The distance between the first hook 41 and the second hook 42 is shortened through the thread, so that the chain and / or the support rod 1 can be tightened to the outer wall of the column 5 to achieve reinforcement of the column.

[0038] See Figure 10-11 The first hook 41 and the second hook 42 have the same structure, forming a universal part, which can reduce production costs and improve assembly efficiency. It includes a metal plate, the head of the metal plate is bent in an arc shape to one side to form a hook body 411, and the hook body 411 can hook the pin shaft 11 or the cylinder in the inner link. The tail of the metal plate is bent toward the other side to form a connecting portion 412. In this embodiment, the tail of the metal plate is bent 90 degrees toward the other side to form a connecting portion 412. A hole body is opened on the connecting portion 412 to form a connecting hole for installing a locking bolt. The hole body can be one or more.

[0039] In the present application, a cylindrical protrusion is provided at each end of the support rod 1, and the cylindrical protrusion forms a pin shaft 11, which is coaxially arranged with the support rod 1. During processing, the pin shaft 11 and the support rod 1 are integrally formed. The diameter of the pin shaft 11 is smaller than the diameter of the support rod 1. Therefore, a limiting step surface is formed between the end face of the pin shaft 11 and the support rod 1, which is used for axial fixation of the chain (chain plate, inner chain link); a retaining spring or cotter pin 12 is provided at the end of the pin shaft 11 for limiting and fixing the inner chain link 2 or the chain plate.

[0040] See Figure 8-Figure 9 The inner chain link includes two parallel and identical first side plates 21 and second side plates 22, both of which are in the shape of an "8". Two cylindrical bodies 23 are arranged between the first side plate and the second side plate. The two cylindrical bodies are arranged in parallel and have a gap between each other. The axis of the cylindrical body is perpendicular to the first side plate and the second side plate. Second axial holes 20 are passed through the two ends of the cylindrical body for allowing the pin shaft to pass through and realize rotation connection; the chain plate includes an inner chain plate 31 and an outer chain plate 32, which have the same structure as the first side plate and the second side plate and are also in the shape of an "8". Two first axial holes 310 for allowing the pin shaft to pass through are provided on the inner chain plate 31 and the outer chain plate, wherein the inner chain plate is used to be installed on the inner side of the inner chain link, that is, close to one end of the support rod, and the outer chain plate is used to be installed on the outer side of the inner chain plate, that is, away from the end of the support rod. The inner chain link is alternately connected with the chain plate.

[0041] In the present application, the diameter of the support rod 1 is smaller than the width of the inner link 2 or the chain plate. Therefore, when it is wrapped around the outside of the column, there is a certain gap between the outer wall of the support rod and the outer wall of the column, and a coating layer, such as a rubber layer, can be provided in the gap; in this embodiment, the ratio of the diameter of the support rod 1 to the width of the inner link 2 or the chain plate is greater than or equal to 0.6 and less than 1. At the same time, the length of the support rod 1 is 0.8 times to 2 times the diameter of the column 5, so that it has optimal bending resistance and connection strength.

[0042] In another embodiment, two support rods form a support rod group, see Figure 6 The difference is that the two support rods are rigidly connected by the inner link plates at both ends to form an integral body, forming a support rod group. Specifically, the inner link plate 31 is sleeved on the end portions of the two support rods 1 and fixed by welding, so that the two support rods and the inner link plates at both ends form a rigid integral structure. The two adjacent support rod groups are connected by inner chain links, and then an outer link plate is arranged on the outside of the inner chain links, and is limited and fixed by a retaining spring or a cotter pin 12. When a retaining spring is provided, an annular retaining groove, i.e., a retaining spring groove, is provided on the side wall of the pin shaft. When a cotter pin is provided, a pin hole 110 is passed through the side wall of the pin shaft.

It has a compact structure, is easy to install and maintain, and has a wide range of applications. A support rod structure is set, which has a large horizontal supporting force and a good reinforcement effect. A double-hook tightening component is adopted, which can be assembled in advance and then connected to the chain through the hook to realize the tightening of the chain. It is easy and labor-saving to operate, can achieve quick connection, and improves installation efficiency. Bolt tightening is adopted, which has a compact structure, is easy to operate, has a large tightening force, and has a self-locking function.
