Description

  The present invention relates to a wiring / pipe material arranged in an exit corner or in an entrance corner where two adjacent wall surfaces are orthogonal to each other, and is arranged in the exit corner and the entrance corner. More specifically, with respect to the protective cover for protecting the installed portion, the protruding corner portion of the wiring / piping material or the entering portion can be used without any trouble even in the case of the non-right angle where the protruding corner portion or the entering corner portion does not intersect exactly 90 °. The present invention relates to a protective cover that can protect corners. In this specification, “wiring / piping material” refers to a hot water supply pipe, a refrigerant pipe for an air conditioner, an electric wire, a cable, or the like.

  For example, when piping a hot water supply pipe along the wall surface of a building, the straight line portion of the hot water hot water pipe piped along the wall surface including the protruding corner portion and the entrance corner portion is a straight straight line. It is protected by a piping part protective cover, and the outlet corner and the inlet corner of the hot water supply pipe are each protected by a dedicated protective cover having an L shape. Each protective cover that protects the outlet corner piping portion and the inlet corner piping portion of the hot water pipe has a connection port that can be connected to the straight piping portion protective cover at both ends, both of which are fixed to the wall surface. A lid that covers the base, the entire base, and the end of the straight pipe protection cover so that the internal space forms a pipe space and is releasably engaged with the base. (Refer to Patent Document 1).

  Here, the base of the protective cover that protects the outlet corner pipe part has an L-shape, and is composed of first and second base plate parts that are integrally molded orthogonally to each other. A pair of left and right engaged portions are formed on each surface of the plate portion on the side forming the 270 ° crossing angle, and a total of two pairs of engaged portions are formed as the entire base. On the other hand, the cover body of the protective cover that protects the protruding corner pipe part has an L shape like the base, and the side that forms the 90 ° crossing angle is opened and faces the opening inside the side wall part. A total of two pairs of engaging portions that are engaged with the engaged portions of the base are formed in the portion.

  In addition, regarding the protective cover for protecting the entrance corner piping portion, the base and the cover constituting the protection cover are both L-shaped in the same manner as the exit corner piping portion protection cover. The formation surface of the engaged portion with respect to each of the first and second base plate portions constituting the base, and the formation position of the opening formed in the lid body so as to be able to cover the base are the outlet corner pipes The configuration that is opposite to the protective cover is different. However, regarding the configuration in which the lid is covered with the base and the piping space is formed inside, and the configuration in which the lid is releasably engaged with the base, the outlet corner piping section and the inlet This is a common configuration for each protective cover of the corner piping section.

  By the way, the corners and corners of the building wall are basically designed so that the crossing angle between adjacent walls is 90 °. The corners and the corners may not be partially orthogonal. In any protective cover of the exit corner piping portion and the entrance corner piping portion, the exit corner portion and the entrance corner portion are dimensioned on the assumption that the adjacent wall surfaces are orthogonal to each other. For this reason, when the exit corner and the entry corner are partially non-perpendicular, the bases in which the first and second base plate parts are orthogonal and the whole is substantially plate-shaped The first and second base plate portions can be forcibly deformed and screwed to the wall surfaces in correspondence with the non-right angle. However, with respect to the lid body, the opposing side plate portions are connected by a back plate portion bent in an L shape and integrated as a whole, and the rigidity against deformation is far greater than that of the base. Therefore, it cannot be deformed corresponding to the non-right angle.

  As a result, when the degree of non-right angle of the protruding corner and the entering corner exceeds a predetermined value, a total of two pairs of engaged members respectively formed on the first and second base plate portions constituting the base. There are cases where both of the two pairs of engaging portions formed on the lid body with respect to the joint portion are not engaged, but only one pair is engaged and the other pair is in an unengaged state. . In this state, since the base and the lid are only engaged with the pair of engaged parts and the engaging part, the lid on the non-engaging side is greatly separated from the wall surface, There may be a large gap between the protective cover of the straight piping part or the protective cover of the protruding corner piping part or the entering corner piping part may be removed due to aging.
