Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a self-adhesive waterproof sheet,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet, and more particularly, to a longitudinally end-portion self-adhesive waterproof sheet used for waterproofing an outer surface of a structure, a manufacturing method thereof, and an apparatus for manufacturing the same.

Fig. 1 shows the construction of a waterproof sheet according to the prior art. The conventional waterproof sheet 1 is formed with a waterproof layer 7 on the surface area formed by the base 3 and the side release sheets 5 and the front side release paper 9 is provided on the other side surface of the waterproof layer 7. The side release sheets 5 and the front release sheets 9 protect the waterproof layer 7, which is highly adhesive during transportation and storage, to prevent foreign matters from being deposited, and are removed at the time of installation. As shown in FIG. 2, when the waterproof layer 7 is attached to the surface of the structure 0, the base 3 is exposed to the outside.

Generally, the waterproof sheet 1 can not cover the entire surface of the whole structure 0 in one sheet, and a plurality of sheets should be used. At this time, a part of the waterproof layer 7 overlaps between the adjacent waterproof sheets 1 as indicated by a dotted circle in FIG. 2, so that leakage does not occur between the waterproof sheets 1.

However, as shown in the drawing, the conventional waterproof sheet 1 has the side release sheets 5 at one side of the width end 1s which is the end in the width direction, and when the side release sheets 5 are removed, (Adhesion of the waterproof layer 7) with the waterproof layer 7 of the waterproof layer 1 can be made possible. In this way, in the conventional waterproof sheet 1, the waterproofing layers 7 can be adhered to each other in the width direction of the waterproof sheet 1, but at the end portion 1e at the longitudinal end of the waterproof sheet 1, (7) could not be adhered to each other. This is because there was no method or apparatus for making the waterproof sheet 1 in the automated continuous process while making the structure at the longitudinal end 1e.

Therefore, conventionally, after the waterproof sheet 1 is once applied to the surface of the structure 0, the waterproof sheet is applied to cover the end portion 1e of the adjacent waterproof sheet 1 at the same time, a joint tape is used, And seals the joint part. In such a method, there is a need to separately perform the operation once the waterproof sheet 1 is installed, and the waterproof layer 7 of the adjacent waterproof sheet 1 is not directly bonded to each other, There is a problem.

Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that, in adding reference numerals to the constituent elements of the drawings, the same constituent elements are denoted by the same reference symbols as possible even if they are shown in different drawings. In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the understanding why the present invention is not intended to be interpreted.

In describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are intended to distinguish the constituent elements from other constituent elements, and the terms do not limit the nature, order or order of the constituent elements. When a component is described as being "connected", "coupled", or "connected" to another component, the component may be directly connected or connected to the other component, Quot; may be "connected," "coupled," or "connected. &Quot;

As shown in the drawings, a preferred embodiment of the waterproof sheet 10 according to the present invention is characterized in that the base 12, the side release sheet 14 and the longitudinal end release sheet 15 form one surface. The base 12 has a flexible property, and a synthetic resin film (for example, a PE film) or a cloth made of a synthetic resin can be used. The base 12 is adhered to the waterproof layer 16 to be described below.

The lengthwise end release 15 is on both of the lengthwise ends 10e in FIG. 3, but it need not be. It is only necessary that at least one of the lengthwise end portions 10e has the lengthwise end releasing paper 15. The side release sheet 14 is located at one side of the width end 10s in the illustrated embodiment, and at least one of the width ends 10s may have the side release sheet 14 thereon. The lengthwise end releasing paper 15 and the side releasing paper 14 are adhered to the waterproofing layer 16 to be described below. However, the surface to which the waterproofing layer 16 is adhered is, for example, It is possible to easily separate it. Therefore, the side release sheet 14 and the end edge release sheet 15 are separated and removed from the waterproof layer 16 while leaving only the base 12 at the time of installation.

The waterproof layer 16 adheres to the surface of the structure and is waterproof. Modified asphalt or non-vulcanized butyl rubber may be used as the waterproof material 16 'for forming the waterproof layer 16. The waterproof layer 16 is positioned on the base 12, the side release paper 14, and the end edge release paper 15.

On the opposite surface of the waterproof layer 16 on which the base 12 is provided, there is a front release sheet 18. The front release sheet 18 is also separated from the waterproof layer 16 during the construction. The side release sheet 14, the longitudinal end release sheet 15, and the front release sheet 18 are intended to solve the problem that foreign matter adheres to the waterproof layer 16 during transportation or storage. The front release paper 18 is also coated with a silicone coating on the surface to which the waterproofing layer 16 is attached so as to be easily separated from the waterproofing layer 16.

In the present invention, when the side release sheet 14 is removed, the width end portion 10s of the adjacent waterproof sheet 10 can be overlapped with the waterproof layer 16. When the lengthwise end release sheet 15 is removed, 10 can be overlapped with the waterproofing layer 16. Therefore, the waterproofing sheet 16 can be overlapped with the adjacent waterproof sheet 10, the width end 10s and the lengthwise end 10e during the construction of the waterproof sheet 10, so that the waterproofing sheet 16 can be self-adhesive.

Next, an apparatus for manufacturing the waterproof sheet 10 having the above-described structure will be described with reference to FIG.

There is a front releasing paper supply unit 20 at the most upstream side of the apparatus. In this case, the front releasing paper 18 is rolled up and then released while being unwound. The front release liner 18 may be conveyed in various manners such as using a roller or pulling the front release liner 18 in the longitudinal direction or one side thereof.

A waterproofing material supply unit 30 is disposed at a position past the front release material supply unit 20. In the waterproofing material supplying unit 30, the waterproofing material 16 'is supplied on the front releasing paper 18 so as to be evenly coated. The waterproofing material supply unit 30 includes a supply hopper 32 containing a waterproofing material 16 'and a pair of supply rollers 34 under the supply hopper 32, The waterproofing material 16 'is applied to a predetermined thickness to form the waterproofing layer 16. Additional rollers may be used to make the waterproofing material 16 'located on the front release paper 18 a more uniform thickness and to make the waterproofing layer 16 uniform.

At the position past the waterproofing material supply unit 30, there is an end release paper supply unit 40. The end portion release paper feeder 40 supplies the lengthwise end release paper 15. The lengthwise end release 15 is positioned across the waterproofing layer 16 formed on the front release liner 18. The length-end releasing paper 15 may also be wound in a roll shape so that the vacuum can be conveyed by the air feeder 42 to be seated on the waterproof layer 16. [ Of course, in the case of winding in the form of a roll, the lengthwise end releasing paper 15 should be cut to an appropriate length (widthwise dimension of the waterproof sheet 10). It is also possible to use a length-end releasing paper 15 previously cut to a predetermined length. And the preliminarily cut length-end releasing paper 15 is sucked and conveyed by the evacuation unit 42 to be adhered to the waterproofing layer 16 to be adhered thereto.

The base feeder 50 is located at a position past the end releasing paper feeder 40. In the base supply part 50, a base 12 attached to one surface of the waterproof layer 16 is supplied. The base 12 may also be rolled and then fed. The width of the base 12 is slightly smaller than the width of the entire waterproof sheet 10. That is, the base 12 is not required in the portion where the side release sheet 14 is located.

A side release paper feeder 60 is disposed at a position beyond the base feeder 50. The side release paper feeding part 60 feeds the side release paper 14. The side release sheet 14 may also be rolled and then fed. It is preferable that the width of the side release liner 14 is such that it can cover the waterproof layer 16 not covered by the base 12 and overlap the base 12 to some extent. At this time, the side release sheets 14 may be partially overlapped on the surface of the base 12. The side release sheets 14 are removed at the time of construction so as not to be disturbed by the base 12 when the side release sheets 14 are removed. The side release sheet 14 may not be used depending on the kind of the waterproof sheet 10. In this case, the side release sheet 14 must not be provided in the side release sheet feeding unit 60. [

After passing through the side release paper feeder 60, the base 12 and the side release paper 14 are covered by the surface of the waterproof layer 16 opposite to the front release paper 18. The waterproof sheet 16 is sandwiched between the base 12 and the waterproof layer 16 and between the side release sheet 14 and the waterproof layer 16 across the waterproof sheet 10 at predetermined intervals. ).

The lengthwise end cutting portion 70 is provided for cutting the waterproof sheet 10 at the portion where the lengthwise end releasing paper 15 is located. The longitudinal end cutting portion 70 produces a waterproof sheet 10 having a certain length through cutting. The length-end cutting portion 70 performs a cutting operation while moving in the same direction and at the same speed as the feed speed of the waterproof sheet 10. [ Once the cutting operation is completed, return to the original position and move again to perform the cutting operation. The lengthwise end cutting portion 70 has a first cutting machine 71 to cut the waterproof sheet 10 continuously fed to a predetermined length.

In Fig. 5, a waterproof sheet 10 having a structure in which a longitudinally-facing end stop 15 is located on both longitudinal end portions 10e is produced. The first cutting machine 71 cuts along the middle portion of the lengthwise end releasable paper 15 and the portion of the side releasable paper 14 covering the lengthwise end releasing paper 15 And then cut and removed. Thus, the lengthwise end release sheet 15, which was covered by the base 12 and the side release sheets 14, is exposed to the outside. Here, cutting of a part of the base 12 and the side release liner 14 is performed by the second cutting machine 72. The second cutting unit 72 performs cutting on the base 12 and the side release paper 14 while being positioned in parallel with the waterproof sheet 10. [ At this time, a portion of the base 12 and the side releasing paper 14 that is to be cut is sucked by the vacuum adsorber 73, and is slightly lifted and held. Of course, the second cutter 72 does not necessarily have to be parallel to the surface of the waterproof sheet 10, and the second cutter 72 may be provided at a slight inclination.

6 shows a part of the apparatus used when the waterproof sheet 10 has the longitudinal end edge 15 only at one longitudinal end 10e. After cutting the waterproof sheet 10 to a predetermined length by using the first cutting machine 71 in the apparatus shown in Fig. 4, the operation of exposing the long-side end release paper 15 using the structure shown in Fig. 5 . 6 is a base cutting portion 80 for cutting and removing a portion of the base 12 covering the lengthwise end releasing paper 15. As shown in FIG. To this end, the base cutter 80 has a base cutter 82 and a lowering roller 84 for lowering the tip of the transported waterproof sheet 10. The front end of the waterproof sheet 10 passing through the downward roller 84 is sagged by its own weight because there is no configuration for supporting the waterproof sheet 10 at the position where the waterproof sheet 10 has passed through the downward roller 84.

At this time, there is a cutting guide 86 for guiding the portion of the base 12 that covers the length-end releasing paper 15. The tip of the cutting guide 86 is located at the front upper portion of the lowering roller 84 so that the tip of the base 12 is moved to the upper surface of the cutting guide 86. The base 12 is flexible but has a certain degree of rigidity and is in contact with the lengthwise end releasing paper 15 and can be easily separated from the lengthwise end releasing paper 15. [ Particularly, the leading end portion of the waterproof sheet 10, in which the waterproof layer 16, the front release sheet 18 and the longitudinal end release sheet 15 are joined, is sagged as shown in Fig. 5 by its own weight.

Therefore, only the base 12 moves to the upper surface of the cutting guide 86, and the base 12 is cut off by the base cutter 82. At the front end of the cutting guide 86, there is a guide slope (not shown) so that the tip of the waterproof sheet 10, which is the part without the base 12, is directed downward.

Hereinafter, a process for manufacturing a waterproof sheet using the apparatus for manufacturing a waterproof sheet according to the present invention will be described in detail. The manufacturing method of the present invention will be described with reference to Fig.

In order to manufacture the waterproof sheet 10 of the present invention, the front releasing paper 18 is first fed (S10). The front releasing paper 18 is flatly moved in a flat state at a constant speed. The waterproofing material 16 'is applied on the front releasing paper 18 so as to have a constant thickness. The waterproofing layer 16 is formed by uniformly applying the waterproofing material 16 'on the front releasing paper 18.

Next, the end release paper 15 is fed onto the waterproofing layer 16 made on the front release paper 18. As shown in Fig. The end release paper 15 is positioned across the waterproofing layer 16 transversely. That is, the end release sheet 15 having a length corresponding to the transverse width of the waterproof layer 16 is positioned on the waterproof layer 16. (S30) The end release sheet 15 is coated with silicone on both side surfaces, (16), but is not bonded to the waterproof layer (16).

Next, the base 12 is supplied to and covered with the surface of the waterproof layer 16 including the end releasing paper 15. (S40) The base 12 has a smaller width dimension than the waterproof layer 16 . This is because the base 12 covers an area other than the area where the side release paper 14 covers the waterproofing layer 16.

The side releasable paper 14 is supplied and positioned on the side of the width end portion 10s of the waterproof layer 16 remaining covered with the base 12. S50 The side releasable paper 14 is covered by the base 12 And covers the remaining area of the waterproof layer 16 that is not covered by the waterproof layer 16. At this time, a portion of the side release paper 14 may be positioned on the base 12.

The step (S40) of supplying the base (12) and the step (S50) of supplying the side release film (14) may be switched to each other. Of course, in this case, it is preferable that the base 12 is not overlapped on the side release paper 14.

Next, the waterproof sheet 10 is cut to an appropriate length. (S60) By this cutting, the waterproof sheet 10 continuously made is cut to a predetermined length.

The waterproof sheet 10 having a shape in which the longitudinal end flank 15 exists in both the longitudinal end portions 10e when cutting is performed along the middle portion of the longitudinal end flank 15 in the process of cutting the waterproof sheet 10, Is created. That is, it becomes the waterproof sheet 10 shown in Fig.

In this case, the base 12 and the side release liner 14 are cut at the lengthwise end 10e. (S70) The base 12 and the side release liner 14 are cut, The lengthwise end releasing paper 15 is exposed to the outside so that the operator can easily remove the lengthwise end releasing paper 15 and the adjacent waterproof sheet 10 and the adjacent longitudinally- The waterproofing layer 16 can be adhered to each other in the longitudinal direction and self-adhesion can be achieved.

On the other hand, when the apparatus employing the configuration shown in Fig. 5 is used, it is possible to provide the waterproof sheet 10 in which the lengthwise end releasing paper 15 is positioned only at one longitudinal end 10e of the waterproof sheet 10. In this case, after the above step S60 is performed, the front end of the waterproof sheet 10 is transferred to the structure shown in Fig. 5, and the base 12 and the side release liner 14, which cover the longitudinal end release sheet 15, Cut the part.

The base 10 and the side releasing paper 14 are guided to the upper surface of the cutting guide 86 by the weight of the waterproof sheet 10 And cut by the base cutter 82. The remaining portion of the base 10 except for the portion corresponding to the longitudinal end releasing paper 15 is adhered to the waterproof layer 16 and is conveyed downward along the downward roller 84. When the front end of the waterproof sheet 10 is conveyed to a certain extent through the lowering roller 84, the waterproof sheet 10 of the waterproof sheet 10 of the portion is cut by the first cutter 71 of the longitudinal end cutter 70, , One waterproof sheet 10 having a predetermined length is made.
