Description

  The present invention relates to a metal cylindrical cover that can be used for appropriate purposes as a decorative cover for piping, a cable binding cover, a heat insulating cover for an exhaust pipe, and the like.

  Conventionally, a heat insulating cover for an exhaust pipe is exemplified by including two heat insulating layers formed in a semicircular shape from a plurality of heat insulating materials, and assembling the heat insulating layer as a cylindrical body by joining the side edges and covering with an aluminum foil. Proposal is made by laminating the cross-sheet as a heat-insulating jacket over the entire outer periphery of the heat-insulating layer, forming a seam on one side as a film hinge with a cross-sheet, and fixing the seam on the other side with the end of the cross-sheet with a heat-resistant adhesive (Patent Document 1).

  The heat insulating cover of the exhaust pipe is configured as a permanent installation type. For this reason, when it is not needed or when it is replaced, it must be removed because it cuts the outer cover cross sheet.

  For example, a steel pipe column protective cover is provided with two cover bodies formed in a semicircular shape from a steel plate material, and a small-diameter cylindrical tube combined alternately is welded and fixed to the side edge of the cover body to separate the steel pipe columns. In addition, the cylindrical tubes of the cover bodies that are opposed to each other are alternately combined, and a stopper pin with a head is inserted into the diameter of the cylindrical tube so as to be joined and fixed as a cylindrical body (Patent Document 2).

  In the protective cover of the steel pipe column, the cover body can be assembled as a cylindrical body and can be disassembled into two as the cover body by inserting and removing the stopper pins with heads into and out of the cylindrical tubes that are alternately combined. However, if the cover body or cylinder is long, it is not easy to insert and remove the stopper pin.

  An example of a wire binding cover is provided with two cover bodies formed in a semicircular shape and two joining bars having a cross-sectional shape, and the side edges of the cover body are fitted into the mouths of the joining bars. In addition, the cover body is opposed to each other, and a ring-shaped binding band is fitted on the outer periphery of the cylinder, so that a cylinder is joined and fixed (Patent Document).

In the cable binding cover, the cover body can be assembled as a cylindrical body by attaching and detaching the binding band, and can be disassembled into two as the cover body. However, in addition to the cover body, a joining bar and a binding band are required, so that not only the number of parts is large, but also the assembly is troublesome.
