Description

  The present invention relates to a cable support fitting mainly used in a place where the amount of cables is large, and relates to a cable support fitting that can be used even in a place with a low ceiling.

  In wiring work for condominiums and the like, support brackets formed in an L shape are used in places where there is a large amount of cable such as a corridor in a living room. This L-shaped support bracket can be used in places with low pockets on the ceiling, such as the lower part of a corridor, and has the advantage that the cables can be wired without being bundled. That is, when cables are bundled, heat dissipation is hindered and overheating may result in an accident, but the possibility of overheating can be eliminated by spreading and supporting the cables on an L-shaped support bracket. In addition, recently, all-electric homes are called, and there is a tendency for many houses to use cooking, hot water supply, air conditioning (cooling and heating), etc., all with electricity. It has increased.

  When such a support metal fitting is used, the screw portion of the support metal fitting is screwed into the insert P that has been driven into the slab, and the cable is supported by the arm portion extending horizontally from the screw portion. For this reason, if an attempt is made to add L-shaped support brackets close to each other, there are cases in which inconvenience occurs when the support brackets are added, such as the horizontally extending arm portions colliding with each other and colliding with each other. Moreover, in order to add support brackets, additional inserts are separately installed on the slab, which further increases the extension work. Therefore, there is a demand for a support fitting that can support as many cables as possible at one support position.

  Patent Document 1 is a cable spacing holder previously proposed by the present applicant. This cable spacing holder is used by being sandwiched between the arm portion of the L-shaped bracket and the screw portion, and is configured to rationally support a plurality of cables on the arm portion of the L-shaped bracket. It is a thing. The cable spacing holder can support a number of cables in an aligned state.

  On the other hand, an inverted T-shaped support fitting has been proposed for the wiring receiver described in Patent Document 2. This inverted T-shaped support bracket can support more cables than the L-shaped support bracket.

Japanese Patent No. 2909898 JP 2004-236499 A

  According to the support metal fitting of Patent Document 1, it is possible to support a large number of cables in an aligned state, but it is difficult to support a large number of cables like the support metal fitting described in Patent Document 2.

  On the other hand, the inverted T-shaped receiver described in Patent Document 2 can support a larger number of cables than an L-shaped support fitting. However, if an inverted T-shaped support is made of a metal material in the same manner as a conventional L-shaped support bracket, there is a disadvantage that the manufacturing cost becomes extremely high, such as difficulty in insulation processing.

  That is, the conventional L-shaped support fitting is bent so that the end portion of the arm portion faces upward in order to prevent the supported cable from falling. Moreover, the metal support fitting is covered with a vinyl chloride tube for the purpose of insulation so that the cable is not in direct contact. However, since this covering tube is mounted by passing a support fitting whose end is bent through the covering tube, with the conventional L-shaped support fitting, this mounting work is difficult. Manufacturing cost was high. In addition, there is a method of applying a coating, but since the support metal is dipped in the coating layer and baked, there are many steps, and the manufacturing cost is increased.

  In this way, when mounting work that is difficult even with an L-shaped support bracket is applied to the inverted T-shaped metal receiver described in Patent Document 2, the screw portion that contacts the cable and the arm portions on both sides thereof In addition, it is necessary to attach a coated tube to each. At this time, even if a coated tube covering the lower end of the threaded portion and a coated tube covering both sides of the arm portion are used, the center portion where the threaded portion of the arm portion is welded cannot be covered. Will be exposed. Therefore, it is necessary to insulate the exposed central portion again. For this reason, the covering operation has to be more difficult, and the manufacturing cost is further increased.

  According to Patent Document 2, a structure in which a metal material is combined with a synthetic resin material is employed in order to insulate the inverted T-shaped receiver. However, when this receiver is connected to the insert P, first, a suspension bolt is connected to the insert P, and then a synthetic resin receiver is connected to the suspension bolt. For this reason, the inverted T-shaped receiver cannot be used in a low ceiling space such as a lower part of a hallway like a conventional L-shaped support fitting. In addition, since it is necessary to connect the synthetic resin receiver to the suspension bolt after connecting the suspension bolt, the connection operation is troublesome twice compared to a metal L-shaped support bracket. Safety issues remain.

  Therefore, the present invention was created to solve the above-mentioned problems, and a metal support metal fitting that can be used in places where the amount of cables is large and the pocket of the ceiling is low and can be used safely. The object is to provide a cable support that can be manufactured at a very low cost.

In order to achieve the above-mentioned object, the first means in the present invention is a support fitting constituted by a bolt portion 1 that can be screwed to the insert P and a support arm 2 that supports a plurality of cables C simultaneously. A cover 3 made of synthetic resin to be attached to the arm 2 is formed, and the cable C is supported on the support arm 2 via the cover 3, and the tip of the support arm 2 of the cover 3 is formed. A locking projection 3A for preventing the locked cable C from dropping is provided upright at the position , and the support arm 2 of the support bracket is formed of a linear rod-shaped metal material, and the bolt portion 1 is It is formed of all screw bolts, and the lower end of the bolt portion 1 is welded to the longitudinal center portion of the support arm 2 to form an inverted T-shaped support fitting .

2nd means WHEREIN: The said cover body 3 penetrates the said bolt part 1, and covers the cylindrical part 3C which coat | covers the lower part of this bolt part 1, and the cover part 3B which coat | covers along the upper surface of the said support arm 2. The locking projection 3A is formed at the tip of the cover portion 3B.

The cover portion 3B of the third means has an inverted U-shaped cross section covering the upper surface of the support arm 2, and a fixing portion 3D for sandwiching the support arm 2 from both sides to the lower end of the cover portion 3B. And a plurality of the fixing portions 3D are formed along the longitudinal direction of the cover portion 3B.

  According to the first aspect of the present invention, the cover body 3 made of synthetic resin to be attached to the support arm 2 is formed, and the cable C is supported on the support arm 2 through the cover body 3. By providing a locking projection 3A for preventing the locked cable C from dropping at the position of the tip of the support arm 2 of the body 3, the cover body 3 can very easily insulate the support fitting. . As a result, the conventional difficult work of attaching the covering tube and the covering coating to the metal support metal fitting is not necessary, and the metal support metal fitting that can be used safely can be manufactured at a very low cost.

Further , the support arm 2 is formed of a linear rod-shaped metal material, the bolt portion 1 is formed of all screw bolts, and the lower end of the bolt portion 1 is welded to the longitudinal center portion of the support arm 2 so as to be inverted T-shaped. Since it is configured so as to form a shaped support metal fitting, it can be used even in places with low pockets on the ceiling, and a large number of cables C can be locked simultaneously at one place. In addition, since the support arm 2 is formed of a linear rod-shaped metal material, there is no need to bend the end portion as in the prior art. As a result, an inverted T-shaped support metal fitting can be easily manufactured, and can be provided at a lower cost.

As in claim 2 , the cover body 3 includes a cylindrical portion 3 </ b> C that penetrates the bolt portion 1 and covers the lower portion of the bolt portion 1, and a cover portion 3 </ b> B that covers the upper surface of the support arm 2.
