Description

Compression band structure installed on a roadside tree The present invention relates to a crossarm band structure installed on a tree, and more specifically, to a crossarm structure installed on a tree (street tree) to support extra-high voltage and low voltage power lines of a power distribution line. Generally, extra-high voltage and low voltage power lines of a distribution line are supported by horizontal crossbars or vertical racks installed on utility poles as shown in Fig. 1. Distribution lines are constructed along roads (sidewalks) to ensure a stable power supply, and as trees (street trees) installed by local governments on sidewalks as shown in Fig. 2 increase and grow every year, the following problems have occurred. First, as trees (street trees) grow, tree pruning is carried out repeatedly every year to prevent power outages caused by contact with power lines, which has resulted in repeated damage to the natural landscape. Second, we continuously incurred significant unnecessary costs by commissioning work to companies with landscaping and planting business licenses for the pruning of trees that grow every year [approximately 64.2 billion won/year expenditure (based on the entire company in 2021)]. Third, administrative resources were consumed due to unnecessary friction with local governments caused by licensing issues and civil complaints regarding tree pruning work. Figure 1 is a site photograph showing extra-high voltage and low voltage power lines being installed on existing utility poles using horizontal crossbars or vertical racks. Figure 2 is a field photograph of a utility pole installed in an overcrowded area and pruned trees near existing power facilities. FIG. 3 is an example diagram showing the reinforcing band of the present invention installed on a tree to support a power line. FIGS. 4(a) and 4(b) are exemplary diagrams showing that the display portion of the reinforcing band of the present invention is exposed as it stretches according to tree growth. FIG. 5 is a plan view showing the reinforcing band of the present invention. FIGS. 6(a)(b) is an enlarged view showing the change state of the expansion portion for part A of FIG. 5. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 3 to 6, in order to fully understand the present invention. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. It should be noted that in each drawing, identical components may be illustrated with the same reference numerals. Detailed descriptions of known functions and components that are deemed to unnecessarily obscure the essence of the present invention are omitted. Referring to FIGS. 3 to 6, the present invention comprises a reinforcing band (30) that is fastened to wrap around a tree (10), wherein the reinforcing band (30) includes a non-stretchable portion (35) forming a circumference; and a stretchable portion (36) disposed on one side of the circumference of the non-stretchable portion (35) and extending to match the diameter of the tree (10) as it grows. The above-mentioned band (30) is composed of a first band body (32a) and a second band body (32b) arranged facing each other in a semi-cylindrical shape to wrap around a tree (10), and a pair of left and right flanges (33a) (33b) are formed protruding outwardly at both ends of the first band body (32a) and the second band body (32b), respectively, which are fastened by a fastening part (34) consisting of a bolt (34a) and a nut (34b). And, the above-mentioned reinforcing band (30) supports the power line (20) by various reinforcing bars (40), such as a conventional ring-shaped support connected to one side of the circumference. The above-mentioned expandable section (36) is arranged in multiple numbers at regular intervals along the circumferential direction of the non-expandable section (35), and the expandable section (36) and the non-expandable section (35) are bonded together at their ends in the circumferential direction. At this time, it is preferable that the above-mentioned non-stretchable part (35) be composed of a synthetic resin, metal, etc., that is not stretchable. It is preferable that the above-mentioned elastic part (36) be composed of high-hardness rubber or the like. It is preferable that the above-mentioned expansion portion (36) has an incision (36a) formed so that it expands in a bellows manner along the circumferential direction. At this time, it is preferable that the above-mentioned expansion portion (36) be formed by injection molding so that it has elasticity in the direction of contraction when no external force is applied to the incision portion (36a). In the above-mentioned cut portion (36a), a mark is formed on the cut surface of the cut portion (36a) that opens into a V shape when the expa
