Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting member for an elbow cover used for protecting a heat insulating material of a curved pipe portion such as a heating and cooling pipe of a building and the like, and an elbow cover to which the mounting member is attached.

[0002]

2. Description of the Related Art A heat insulating material such as glass wool, which is molded into a predetermined shape in order to enhance the heat insulating property, is wrapped around a heating and cooling pipe of a building or the like. A method of covering the upper part with an elbow cover made of a flame-retardant material (such as vinyl chloride) is used. On the surface of the elbow cover, for example, an adhesive aluminum glass cloth sheet (glass fiber) is used to improve the appearance quality. Aluminum foil is adhered to a cloth, and a surface mounting member made of a sheet or the like having an adhesive applied on one surface) is attached.

As this mounting member, for example, there is known a mounting member formed by cutting an adhesive aluminum glass cloth sheet whose surface of an adhesive is protected by a release paper into a bias and comprising at least 5 pieces (actually, As shown in FIG. 5, each of the component pieces 1 to 5 constituting the cover member is provided on the surface of the elbow cover body 6 (1, 5).
→ (2, 4) → 3 are attached in this order. In addition, 7 is a display line showing the overlap margin at the time of pasting. Since the above-mentioned mounting member is divided into the respective pieces 1 to 5, it is suitable for sticking to a curved surface such as the surface of the elbow cover main body 6 without wrinkles, but accurate positioning at the time of sticking is extremely important. It has the problem of being difficult.

That is, first, when attaching the piece 1 to the surface of the elbow cover body 6, as shown in FIG.
The edge of the elbow cover body 6 to the end, and the center of the piece 1 is attached to the center line 6a of the spine of the elbow cover body 6 (Fig. 6 (b)), and then to the lower side. As shown in FIG. 6 (c), if the positioning in the front / rear / left / right direction or the rotation direction is slightly misaligned as shown by the arrow in FIG. 6 (b), the elbow cover main body 6 is moved as shown in FIG. 6 (c). On the lower side, a large deviation 8 will occur. Then, when trying to correct this in the middle and sticking while pulling in the direction for eliminating the deviation 8 (see the arrow in FIG. 7), slack occurs on the opposite side and large wrinkles 9 occur.

When the release paper is peeled off, the adhesive aluminum glass cloth sheet rolls into a spiral shape. Therefore, with the piece 1 stretched left and right, it is aligned with the center line 6a of the spine of the elbow cover body 6. However, at this time, a positional deviation in the rotation direction shown in FIG. 6B is likely to occur, and even if the deviation is about 1 degree, a deviation 8 (FIG. (C)) becomes several millimeters, and if it is attached while pulling in order to eliminate this deviation 8, wrinkles 9 (FIG. 7) as described above will occur.

When the pieces 2 or 4 are attached after the pieces 1 and 5 are attached, the display line 7 formed on the pieces 1 or 5 can be used as an aid for positioning. However, this is also useful when the piece 1 or 5 is pasted at the exactly intended place, but when the piece 1 or 5 is pasted at a slightly displaced position, the next An error may be added when the pieces 2 or 4 are attached, and when the last piece 3 is attached, the entire surface of the elbow cover body 6 cannot be covered, and the appearance quality is significantly impaired.

For larger elbow covers, the number of pieces per one elbow cover body is 7, 9 and 11.
Although the number of designs increases, the difficulty of positioning increases as the number of pieces increases. And
In order to prevent the appearance quality from being impaired, it is necessary to be very careful when attaching the pieces, the attachment time will be long, and the product price of the elbow cover with the attachment material attached will be extremely high. It will be something like.

Further, since it is necessary to prepare at least 5 pieces of the above-mentioned mounting members for all sizes of about 20 kinds of elbow covers, it is necessary to manage more than 60 kinds of pieces, which is extremely difficult. It was complicated.

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the above-mentioned conventional mounting member of the elbow cover, and the positioning when the mounting member is attached to the elbow cover body is accurate and easy. It is an object of the present invention to obtain a surface mounting member that can be used and can easily manage pieces.
Another object of the present invention is to obtain an elbow cover to which such a cover member is attached.

[0010]

The surface mounting member of the elbow cover according to the present invention comprises a laminated sheet in which a base material and an aluminum foil are laminated and an adhesive layer is protected by a release paper on one surface thereof. , The laminated sheet is cut on a plurality of pieces adhered to the surface of the elbow cover body in a predetermined arrangement, leaving a predetermined width in the central portion, and the plurality of pieces form the predetermined arrangement to each other. It is characterized in that it is formed of an integral member connected at the central portion.

In the above-mentioned mounting member, it is preferable that cuts are formed in the release paper on both sides of the central portion of the plurality of pieces, and the laminated sheet is attached to the maximum curved portion of the elbow cover body. At least 5 pieces of a piece to be attached, a piece to be attached to a portion displaced from the maximum curved portion to a straight portion, and a piece to be attached to an end portion from the displaced portion are cut into at least 5 pieces. Preferably, a cut line is formed in the release paper at a position closer to the center portion of the predetermined size width from the left or right edge of one or more of the plurality of pieces, and the center is further provided. Notches are formed at the center positions in the width direction at both ends of the part.

The elbow cover according to the present invention is one in which the above-mentioned mounting member is attached to the elbow cover body. That is, it is composed of a laminated sheet in which a base material and an aluminum foil are laminated and an adhesive layer is provided on one surface of the elbow cover. The one-piece surface mounting member connected by
The adhesive layer is provided inside, and the adhesive member is attached such that the central portion of the covering member is located at the central portion on the outer curved side of the elbow cover.

In the above elbow cover, it is preferable that the mounting member is attached to the maximum curved portion of the elbow cover, and the portion attached to a portion displaced from the maximum curved portion to the straight portion. It is composed of at least 5 pieces of pieces that are attached to the ends from the displaced parts, and preferably, a position closer to the center part by a predetermined width from the edge of one or more pieces that form the mounting member. The release paper is attached on the adhesive layer in the section up to, and this portion is not attached to the elbow cover.

[0014]

The above-mentioned mounting member of the elbow cover is a one-piece mounting member in which a plurality of pieces attached to the surface of the main body of the elbow cover are arranged in a predetermined arrangement and are connected to each other at the central portion. While each part is sequentially attached to the surface of the elbow cover main body, the entire elbow cover is mounted by this one piece.

The above-mentioned cut lines are formed in the release paper on both sides of the central portion of the plurality of pieces, so that when the release paper of each piece is peeled off, the central portion can be peeled off at the same time.
This is so that the parts other than the central part can be peeled off separately for each part.

A cut line is formed on the release paper at a position closer to the center of a predetermined size width from either the left or right edge of one or more of the plurality of pieces forming the cover member by the cut line. This is because the release paper on the edge side is left and this part is not attached to the main body of the elbow cover, which can be used for temporary fixing of the elbow cover, as will be described later in Examples. When the cut line is formed on two or more pieces of release paper, it is preferable that the cut lines are formed on the same left and right sides as viewed from the center.

The reason why the notch is formed at the center position in the width direction at both ends of the central portion of the cover member is to be used as a standard for initial positioning when the cover member is attached to the main body of the elbow cover. Accurate positioning is facilitated by matching this cut with the center line.

The above-mentioned mounting member is attached such that the central portion thereof is located at the central portion on the outer curved side of the elbow cover body, but the individual pieces constituting the above-mentioned mounting member are integrally connected to each other at the central portion having a predetermined width. Therefore, the mounting member in the central portion on the outer curve side of the elbow cover is connected through each piece, and no seam appears there.

[0019]

Embodiments of the present invention will be described below with reference to FIGS. First, FIG. 1 is a plan view of a mounting member 10 of an elbow cover according to the present invention. In the mounting member 10, a glass cloth 11 and an aluminum foil 12 are laminated via a polyethylene laminate layer 13, an adhesive layer 14 is formed on the surface on the side of the aluminum foil 12, and a release paper 15 is formed thereon.
Is a laminated so-called adhesive aluminum glass cloth sheet, and is a one-piece mounting member in which five pieces 16 to 20 attached to the surface of the elbow cover body 6 (see FIG. 2) are connected to each other at the central portion 21. The piece 18 is a piece attached to the maximum curved portion of the elbow cover body 6, and the piece 17
Reference numerals 19 and 19 denote pieces attached to the portion displaced from the maximum curved portion to the straight portion, and pieces 16 and 20 are pieces attached to the end portions from the displaced portion.

The individual pieces 16 to 20 are cut from an adhesive aluminum glass cloth sheet by press punching, leaving a central portion 21 having a predetermined width w. At that time, on both sides of the central portion 21, cuts 22 extending over the respective pieces 16 to 20 are formed parallel to each other on the release paper 15, and at the same time, the pieces 1 at both ends
A cut 23 is formed in the release paper 15 at a position closer to the center by a predetermined dimension width h from one edge of each of 6 and 20, and further, at the center positions in the width direction of both ends of the center 21, the entire adhesive aluminum glass cloth is cut. Notch 24 over thickness
Is formed. In addition, the cuts 22 and 23 are formed by adjusting the amount of protrusion of the blade at the time of punching the press, and the release paper of the central portion 21, the release papers on the left and right of each of the pieces 16 to 20, and the piece 16 of the cut piece. The release papers at the end portions of 20 and 20 can be peeled off independently.

A procedure for positioning the mounting member 10 on the elbow cover body 6 and subsequently attaching the respective pieces will be described with reference to FIGS. 2 and 3. First, the procedure for positioning the cover member 10 on the elbow cover body 6 is to place the release paper 15 side of the cover member facing upward, peel the release paper in the central portion 21 to expose the adhesive layer 14 (see FIG. a)), then a notch 24 (24
a) is aligned with one end of a center line 6a formed at the center of the elbow cover body 6 on the outward curve side (FIG. 2 (b)),
While carefully paying attention so that the center line 6a of the elbow cover does not deviate from the center of the center portion 21 of the cover member, the outer curved side of the elbow cover body 6 is rotationally moved so as to be pressed onto the adhesive layer 14 of the center portion 21. (FIG. 2 (c)), and finally, the other end of the center line 6a of the elbow cover is the central portion 2
It fits in the notch 24 (24b) formed in the other end of 1. In this way, the center of the central portion 21 of the mounting member 10 is attached so that the center of the elbow cover 6 exactly coincides with the center line 6a of the elbow cover 6, and the positioning of the respective pieces 16 to 20 with respect to the elbow cover body 6 is completed (see FIG. Two
(D)).

Next, the piece 16 (piece 20 located at the end)
The release paper 15 on one side 16a
When peeled from the side (Fig. 3 (a)) and pulled along the elbow cover body 6, one side 16a of the piece cannot be wrinkled and is smoothly attached to the elbow cover body 6 (Fig. 3 (b)). The release paper 1 at this time
5 has a cut line 23, so one side of the piece 1
6a is to be attached to the elbow cover 6 up to the cut 23, and the release paper 15 is not peeled off at the end edge side of the cut 23.

The above-mentioned pasting work is similarly performed for all the remaining pieces (16 → 20 → 17 → 19 → 18 in the order). For the pieces having the cuts 23, the cuts are made from the cuts 23. The release paper 15 was not peeled off on the edge side, and the tip of the piece not having the cut 23 was properly folded inside the elbow cover 6, and the entire surface was covered with each piece 16-20. Completed elbow cover 2
5 is obtained (FIG. 3 (c)). In the elbow cover 25, as shown in the figure, there are unpeeled portions 26 and 27 where the release paper 15 remains without being peeled off one by one on the edge side of the pieces 16 and 20.

The unpeeled portions 26 and 27 are used as temporary fixing members when the elbow cover 25 is mounted as a heat insulating cover for piping. That is, as shown in FIG. 4, the elbow cover 25 is put on the pipe (not shown),
The diameter is reduced so that one side of the opening edge on the inwardly curved side is different from the other side, the inner surface of the elbow cover 25 is brought into close contact with the pipe, and in that state, the release paper 15 at the unpeeled portions 26, 27 is removed. It is to be peeled off and temporarily fixed.

According to the cover member 10 of the above-mentioned embodiment, the positioning of each of the parts constituting the cover member can be performed quickly and accurately, and the parts can be easily attached to each other. Since they are all connected, management complexity is avoided. Further, in the elbow cover 25 to which the cover member of the above-mentioned embodiment is attached, the cover member at the central portion on the outer curve side is connected through each piece and there is no joint, so that the cover member of that portion is turned up when carrying or mounting on a pipe. There is no inconvenience.

In the above embodiment, the cover member is composed of 5 pieces, but the number of pieces of the cover member can be appropriately determined according to the size of the elbow cover. Further, in the above-mentioned example, as the laminated sheet for the mounting member, the adhesive aluminum glass cloth sheet was used, but other adhesive laminated sheets having different base materials such as aluminum walliff and aluminum craft can also be used. The adhesive layer may be laminated on either the base material side or the aluminum foil side. On the other hand, as the elbow cover body, in addition to flame-retardant vinyl chloride, it is made of expanded polystyrene (polystyrene), polyethylene foam,
Made of polypropylene foam, polyurethane foam,
Other various resins (polycarbonate, FRP, etc.) can be used as appropriate.

Further, in the case of a super-large elbow cover, the adhesive aluminum glass cloth sheet is generally 1 m wide, and the press or the like is also generally limited to 1 m wide, so that one sheet as shown in FIG. The problem of not being able to produce sheets actually occurs. In this case, the cover member is made in the same way as in FIG. 1A, but it is also possible to divide the cover member into two and attach the super-large elbow cover with two sheets. That is, when the sheet is cut laterally at the central portion of the piece 18 of FIG. 1A, a vertically symmetrical sheet is formed. However, the notches 24 are formed in the upper and lower portions of each of the two-divided sheets, and the method of FIG. 2 is used. Paste in the same way. In this way, in the case of a super-large elbow cover, a method of attaching each half surface may be adopted. In the case of splitting into two, it is necessary to manufacture punching dies of two presses when splitting asymmetrically, but one splitting die is sufficient when splitting vertically or horizontally.

[0028]

According to the mounting member of the present invention, the positioning at the time of attaching to the elbow cover body can be accurately, easily and quickly performed. Further, since the parts constituting the mounting member are integrated members which are connected to each other, the management of the mounting member can be facilitated, and this point does not change regardless of the number of parts constituting the mounting member. Absent. Further, the elbow cover according to the present invention has no seam on the outer cover side central member, so that the outer cover member does not flip over during carrying or mounting, and does not come off during use. Is stable. Furthermore, when an unpeeled portion is provided on the edge side of one or more pieces, it can be used as a one-touch temporary fixing when attaching the elbow cover, which is very convenient in terms of work.
