  10. A wire rope mounting bracket for steel pipes, which connects a wire to a mounting bracket that clamps the side of a steel pipe with fixing brackets and secures both longitudinal ends of the fixing brackets with fixing bolts, wherein a spring member is attached to one of the fixing bolts, and the fixing bracket that clamps the steel pipe is configured to close due to the elastic force of the spring member, the ends of the fixing bracket spread out in a roughly V shape when viewed from the axial direction of the steel pipe, and it is possible to insert the steel pipe from the side when one of the fixing bolts is missing .

Description

This invention relates to a wire rope mounting bracket for steel pipes, suitable for attaching wire ropes to steel pipes for preventing swaying of electronic display boards, lighting fixtures, and other equipment suspended from the structure of, for example, a train station. The renovation of station building electronic display boards and lighting fixtures must be carried out within the limited time between the last and first trains, so efficiency is required even in the work of preventing equipment from shaking. However, conventional mounting brackets required a great deal of effort to install. The mounting bracket described as prior art in Patent Document 1 is attached to a suspension bolt. It has a structure in which a suspension bolt is clamped between a pair of fixing brackets, and both ends of the fixing brackets are secured with a pair of fixing bolts. Furthermore, fully threaded bolts for preventing sway are connected to the fixing bolts that secure the fixing brackets. On the other hand, mounting brackets for steel pipes used in station buildings and similar structures also utilize fittings similar to those described in Patent Document 1. Specifically, they consist of a pair of fixing brackets that clamp onto the steel pipe and a pair of fixing bolts that secure both ends of the fixing brackets. However, in mounting brackets for steel pipes used in station buildings and similar structures, wire ropes or turnbuckles are connected instead of threaded bolts to prevent swaying of the equipment. Patent No. 6539110 This is a perspective view showing one embodiment of the present invention.This is a plan view showing one embodiment of the present invention.This is an exploded perspective view showing the main parts of the present invention.This is a plan view of the fixing bracket of the present invention.(i) to (ii) are explanatory diagrams illustrating the fixing procedure of the present invention.(a) and (b) are perspective views of the main parts showing each usage state of the present invention. The mounting bracket of this invention is used to attach wires P and turnbuckles, which are used to prevent swaying of electronic display boards, lighting fixtures, etc., suspended from the structure of buildings such as train stations, to steel pipes Q (see Figures 6(a) and (b)). The main components of this invention include a fixing bracket 1, a fixing bolt 6, a fixing nut 7, and a coil spring 8 (see Figure 1). The fixing bracket 1 is a strip-shaped member that secures the steel pipe Q by clamping its side. It consists of a contact portion 2 that clamps the steel pipe Q and connecting portions 3 extended from both ends of the contact portion 2 (see Figure 2). The connecting portions 3 are then secured to each other with fixing bolts 6, and a bracing wire P is connected to a burring 5 through which these fixing bolts 6 are inserted. While the illustrated fixing bracket 1 uses a pair of identical brackets, these may be integrally molded. A spring member is attached to one of the fixing bolts 6, and the elastic force of the spring member is configured to close the pair of fixing brackets 1 that sandwich the steel pipe Q (see Figures 5(a) and (b)). The illustrated spring member is a coil spring 8. The coil spring 8 is installed between the fixing nut 7, which is screwed to the fixing bolt 6, and the fixing bracket 1, and the compressive biasing force of the coil spring 8 is configured to maintain a constant rotational position between the fixing brackets 1. In the illustrated example, a nut with a washer is used for the fixing nut 7 (see Figures 2 and 3). Furthermore, the spring member does not necessarily have to be a coil spring; any material that has a biasing force to bring the fixing brackets 1 closer together is sufficient, for example, a leaf spring material could also be used. The fixing bolts 6 shown in the illustration are fixed bolts with square roots, and the bolt insertion holes 4 form a fitting recess 4A that fits the square root portion 6A of the fixing bolt 6 (see Figure 3). The fixing bolts 6 are then inserted through each bolt insertion hole 4 and secured by screwing on the fixing nuts 7 (see Figure 2). Since the fixing bolts 6 inserted through the bolt insertion holes 4 are fixed in the fitting recess 4A, they do not rotate when the fixing nuts 7 are screwed on. Although not described in this embodiment, if hexagonal bolts are used, the fitting recess 4A can be replaced by providing a projection on the fixing bracket 1 such that an embossed or similar object contacts at least one side of the bolt head, to the extent that the fixing bolt 6 does not rotate. Furthermore, the bolt insertion holes 4 are equipped with burrings 5 that protrude in the direction of the opposing fixing brackets 1 (see Figure 2). These burrings 5 are configured to contact each other when the steel pipe Q is clamped between the fixing brackets 1. As a result, the contacting burrings 5 ensure an appropriate gap when conne
