Description

  The present invention relates to a hand-held electric peeling tool for peeling off a heat insulating layer (foamed urethane layer) on the back surface of a building outer wall material, and parts constituting the electric peeling tool.

  Building exterior wall materials are known in various structures, but the most commonly used structure is made of foamed resin with a heat insulating function on the back of a metal plate (hereinafter referred to as “surface plate”). The formed layer (foamed urethane is frequently used, hereinafter referred to as “foamed resin portion”) is provided (see, for example, Patent Document 1). When discarding the building outer wall material, it is necessary to separate the surface plate and the foamed resin portion in consideration of resource recycling.

  As the separating means, the foamed resin portion may be peeled off from the surface plate. Previously, the foamed resin portion was scraped off with a spatula-like hand tool and separated.

  In addition, peeling instruments using hand-held power tools have been proposed for various objects. For example, Patent Document 2 discloses a hand-held stripping tool for a canvas on the back of a handrail of a passenger conveyor, and Patent Document 3 discloses a hand-held electric scaly remover. The blade body is operated so as to pierce in the removing direction, and the blade portion that performs the peeling action is vibrated in the advancing direction.

  By the way, when peeling off the foamed resin part of the building outer wall material from the surface plate, the conventional scraping work with a spatula-like instrument is cumbersome and the separated resin material is scattered, and the cleaning work (resin material) The work was also very inefficient.

  Further, in the above-described conventional hand-held power tool for peeling, when the blade body corresponding to the peeling of the foamed resin portion is employed, the blade body portion that performs the peeling action vibrates back and forth in the peeling advance direction. . And since the width | variety of an outer wall material is wide, it operates so that it may push forward with respect to the peeling direction, moving a blade body right and left.

  However, since the foamed resin portion has deteriorated, in the peeling by the piercing of the blade body, when the piercing and lifting, the foamed resin portion is cracked and the foamed resin portion is not separated into one lump, Some of them are pulverized and scattered, and it is necessary to carry out cumbersome post work (work for collecting separated resin materials) as in the case of manual work.

  Further, in the outer wall material, the surface plate is not necessarily formed flat, and there is a wall plate having a rectangular wave section for decoration of the outer wall. Even in such a specially shaped outer wall material, it is desired to efficiently remove and remove the foamed resin portion.

  Therefore, the present invention constitutes a hand-held electric peeling tool capable of effectively peeling the foamed resin portion and the electric peeling tool with respect to the outer wall material provided with the heat insulating layer (foamed resin portion) on the back surface of the front plate. This is a suggested part.

  The component of the electric peeling tool of the back surface heat insulation layer of the building outer wall material according to the present invention (Claim 1) is a component to be mounted on a predetermined handheld electric tool body provided with a left and right laterally moving vibration shaft below the front part, It is a thin plate and has a through-hole that can be attached to the vibration shaft of the tool main body at the base, and a blade body component with a blade that has a central portion bulging at the front edge, and an attachment that can be fixedly attached to the tip of the tool main body. And a hook part having a hook-shaped inclined guide surface part whose tip is located in the vicinity of the upper surface behind the front edge of the blade part attached to the tool body when the tool body is mounted on the tool body.

It is characterized by mounting the parts.

  Thus, in the electric peeling tool in which the parts are mounted on a predetermined hand-held power tool body, the blade body part (blade body part mounted on the tool body) causes left and right side vibrations, so the foamed resin portion is formed on the back surface of the front plate. When the blade body part is inserted between the surface plate and the foamed resin part with respect to the outer wall material provided with the tool, the blade body part is separated between the foamed resin part and the surface plate by the lateral vibration of the blade body part. When the main body is moved forward and leftward to both ends of the outer wall material, the foamed resin part is sequentially peeled off from the surface plate, and the foamed resin part peeled off as the tool main body is advanced is It collides with the inclined guide surface portion of the attached saddle component) and is rolled up, and the foamed resin portion after separation becomes a single sheet.

  Further, the part according to the present invention (Claim 2) is a corrugated part in which the entire front edge of the blade part is formed in a corrugated shape, and the central part of the front edge protrudes from the side part, particularly in the blade part. The lateral cutting is effectively performed by the corrugation.

  Furthermore, the part according to the present invention (Claim 3) is a blade part of an outer wall member provided with a comb-like blade part protruding at a predetermined interval on the front edge, and provided with a protrusion on the surface, particularly in a blade part. It can cope with separation of the foamed resin portion on the back surface of the sheet.

  Moreover, the electric peeling tool of the back surface heat insulation layer of the building outer wall material according to the present invention (Claims 5 and 6) is formed by attaching a handle portion to the tool body, and is connected to the tool body at the tip. An operation component including a connecting portion, a rod-shaped handle portion having a predetermined length, and a grip portion protruding laterally from an intermediate position of the rod-shaped handle portion is mounted on the tool body.

  Therefore, the tool can be operated using the handle, and further, when the rod-shaped operating component is mounted on the tool body, the work can be performed while standing.

  The electric peeling tool for the heat insulation layer on the back surface of the building outer wall material according to the present invention and its parts are as described above, and the foamed resin portion on the back surface of the outer wall material can be separated by mechanical work. Is separated into a sheet shape, and the handling after the separation is facilitated, and the disposal of the outer wall material can be performed efficiently.

  Next, an embodiment of the present invention will be described. The electric peeling tool shown in the embodiment of the present invention is composed of a tool main body 1, a blade body portion 2 and a flange portion 3 mounted as parts.

  The tool body 1 is an existing tool, and includes at least a drive motor and a left and right lateral vibration shaft 11 that is vertically suspended from the front. Specifically, the tool body 1 is a clipper called a hedge trimmer (mowing machine). In the type of mower, there is provided a mounting part 12 of a movable blade body that is connected to the vibration shaft 11 and makes left-right lateral vibration.

  A ring-shaped handle 13 surrounding the tool body 1 is fixed to the lower surface of the tool body 1 with mounting bolts 14.
