Description

  TECHNICAL FIELD The present invention relates to a gap waterproof sheet material for a building which can be waterproofed by closing a gap when constructing a roof or a wall of a building such as a house.

  2. Description of the Related Art As a conventional gap waterproof sheet material for buildings, a sheet having a corrugated sheet formed by corrugating the sheet surface is known (see, for example, Patent Document 1). This uneven strip is for maintaining air permeability, and the uneven strip from one end to the other end in the width direction of the sheet material is continuously formed on the entire surface.

  The thing of the same literature is what a filter, such as a nonwoven fabric, is affixed on either side of the synthetic resin core material which forms a mountain-shaped unevenness | corrugation in the shape of a bellows, and the strength is complemented by the filter. . However, instead of being strong, there is not much flexibility, and it is considered that it is assumed to be used in a flat portion where the need for bending is low, as described in the drawings of the same document.

In addition, for a long sheet base material having flexibility such as aluminum, an uneven strip is formed in the short direction, and an adhesive layer is formed on either the front surface or the back surface of the sheet base material. The provided waterproof sheet material is also known. Since this product does not have a filter layer, it can be easily expanded and expanded or folded along the uneven direction, thereby allowing the adhesive layer to be applied to curved surfaces such as tile surfaces. Can be brought into close contact with each other. In addition, in the case where the ridges are crushed along the direction perpendicular to the concavo-convex, it can be easily bent along the folds, so it is also used for three-dimensional places such as the corners of parallel walls can do.

  However, the above-mentioned waterproof sheet material has a three-dimensional shape that is slightly thick due to the uneven ridges, so that the waterproof sheet material is difficult to adhere to an object to be fixed, and is difficult to nail and tacker. There's a problem. It should be noted that nailing and the like are relatively easy at the right place of the folded strip formed by crushing the concavo-convex strip, but since the fold strip is formed in a straight line in a direction perpendicular to the concavo-convex strip, a plurality of folds are formed. If the strip is not formed, there is no degree of freedom for nailing in the direction of unevenness.

  Further, when nailing or the like is performed on the waterproof sheet material at equal intervals, there is no standard, and there is a problem that construction is troublesome.

  In addition, with the conventional one, it is easy to bend along the concavo-convex direction (the short direction of the long material), but since there is a bulge due to the concavo-convex, it is attached with high adhesion on a curved surface with a small radius. It is difficult. Similarly, it is expected that the adhesion in the vicinity of the folds will be lowered with respect to the bending in the direction perpendicular to the unevenness (longitudinal direction).

  The present invention has been proposed in view of such circumstances, and its purpose is to easily nail and tacker the object to be fixed, and to provide a clearance for a building having a high degree of adhesion at the fixing point. It is to provide a waterproof sheet material.

  In order to achieve the above object, the gap waterproof sheet material for buildings according to claim 1 is formed along a direction perpendicular to the ridges on a sheet base material formed by processing a corrugated portion composed of alternately concavo-convex ridges. In this case, the corrugated portion is formed by intermittently forming concave and convex strips, and a concave and convex direction smooth portion is formed between the separated corrugated portions. It is characterized by having.

  The gap waterproof sheet material for buildings according to claim 2 is further formed with a concavo-convex orthogonal direction smooth portion along the concavo-convex orthogonal direction of the sheet base material, which divides the concavo-convex strip.

  In the gap waterproof sheet material for buildings according to claim 3, the uneven direction smooth portions are formed at substantially equal intervals.

  The gap waterproof sheet material for a building according to claim 5 is an architecture in which a pressure-sensitive adhesive layer is formed along a direction orthogonal to the ridges on a sheet base material formed by processing corrugated portions consisting of alternately continuous ridges. In the gap waterproof sheet material for objects, the sheet base material is characterized in that a concavo-convex orthogonal direction smooth portion is formed in a direction orthogonal to the concavo-convex strip.

  In the gap waterproof sheet material for buildings according to claim 6, the pressure-sensitive adhesive layer is formed on at least one side of the front surface or the back surface of the unevenness orthogonal direction smooth portion.

  According to the gap waterproof sheet material for a building according to claim 1, since the uneven direction smooth portion is formed between the corrugated portions separated by intermittently separating the uneven strip, it is easy to nail, tacker, etc. Furthermore, the nailing location in the uneven direction can be freely selected. Moreover, if the smooth part is applied to the corner part or the curved part of the object, the closeness at those parts is increased, and the waterproof effect is further enhanced.

  According to the gap waterproof sheet material for a building according to claim 2, since the unevenness direction smooth portion is further formed in addition to the uneven direction smooth portion, it can be used for target portions of various shapes of the building. .

  According to the gap waterproof sheet material for a building according to claim 3, since the uneven direction smooth portions are formed at substantially equal intervals, a nail is used when a long one is used with respect to a parallel wall or the like. Strike etc. can be done at equal intervals. Moreover, since the uneven | corrugated direction smooth part becomes a standard of a nail location, construction efficiency improves.

  According to the gap waterproof sheet material for a building according to claim 4, since the adhesive layer is also formed in the uneven direction smooth portion, it can be easily attached even to an object that cannot be nailed or tacked. Can be fixed.

  According to the gap waterproof sheet material for a building according to claim 5, since the uneven orthogonal direction smooth portion is formed, it is easy to nail, tacker, etc., and the nail location in the uneven orthogonal direction is free. Can be selected. In addition, in the case where the concave / convex orthogonal direction smooth portion is provided at one end of the concave / convex direction and the adhesive layer is provided at the other end, it is fixed so as to straddle, for example, a pier that can be nailed and a roof that cannot be nailed It can be used effectively in some cases.

  According to the gap waterproof sheet material for buildings according to claim 6, since the adhesive layer is formed in the concave and convex orthogonal direction smooth portion, it can be fixed to the object double with an adhesive and a tucker, Secure fixing can be performed.

FIG. 1B is a back view of the waterproof sheet material, FIG. 1C is a schematic cross-sectional view of the waterproof sheet material in the direction perpendicular to the concave and convex portions (longitudinal direction in this example), and FIG. It is a schematic sectional drawing of the uneven | corrugated direction (short direction in this example) of the waterproof sheet material. FIG. 2 is a perspective view showing a wound state of the waterproof sheet material.

This waterproof sheet material 10 is provided with sheet-like base material (sheet base material) 10a made of a metal such as aluminum whose front and back surfaces are coated with a resin or the like, and alternately provided with uneven ridges 11a. The pressure-sensitive adhesive layer 14 is formed along a direction orthogonal to the direction. Since it is in the form of a sheet, it can be easily folded along the concave and convex direction, and is stored and transported in a state of winding a long one as shown in Fig. 2. Cut to use.

  On the surface of the waterproof sheet material 10, a corrugated portion 11 composed of a plurality of concave and convex strips 11a is formed, and the corrugated portion 11 is intermittently formed by concave and convex strips 11a by the concave and convex direction smoothing portions 12 formed at equal intervals. It is separated. Moreover, the uneven | corrugated orthogonal direction smooth part 13 is formed in the approximate center of the uneven | corrugated direction along the longitudinal direction of the sheet | seat base material 10a so that the uneven | corrugated strip 11a may be parted. Therefore, the corrugated part 11 is separated and formed in a two-stage, multi-row grid pattern by these vertical and horizontal smoothing parts.

On the other hand, since the back surface of the waterproof sheet material 10 is processed with unevenness, the corrugated portion 11, the uneven direction smoothing portion 12, and the uneven orthogonal direction smoothing portion 13 appear like the front surface, and at one end in the short direction. An adhesive layer 14 made of butyl rubber or the like is formed. Prior to use such as storage and carrying, a protective tape 14a (shown in FIG. 2) is affixed to the adhesive layer 14 , and the protective tape 14a is peeled off during construction.

  The pressure-sensitive adhesive layer 14 has a function of fixing the waterproof sheet material 10 to an object and also has a waterproof function, and rainwater from the outside to the back surface of the waterproof sheet material 10 is attached to the object. To prevent water from entering. The pressure-sensitive adhesive layer 14 may be formed on both ends of the sheet substrate 10a, or may be formed on the concave / convex orthogonal direction smoothing portion 13 or the concave / convex direction smoothing portion 12, and may be formed at various locations depending on the application. That's fine.

  Next, various usage examples of the waterproof sheet material 10 will be described with reference to FIGS.

  FIG. 3 is a view showing an example of use of the waterproof sheet material 10 in a large ridge portion of a house, and FIG. 3 (a) is a perspective view showing a state in which the waterproof sheet material 10 is attached in the large ridge portion. FIG. 2 is a schematic longitudinal sectional view of a large building.

  In the large ridge part, the waterproof sheet material 10 has an end portion of one tile 22 arranged on both ends of the roof sheet 25 arranged along the top of the roof where the two field boards 21 abut each other. To the end of the other tile 22 along the longitudinal direction of the purlin 25. The waterproof sheet material 10 may be disposed so as to be bent along the shape of the purlin 25 so as to be in close contact with each other, and both side ends thereof are fixed to the roof tiles 22 on both sides. In this case, the waterproof sheet | seat material 10 which provided the adhesive layer 14 in the width direction both ends can be used conveniently. Further, the two waterproof sheet members 10 may be used so as to overlap each other on the upper surface of the purlin 25.

  Furthermore, in order to securely fix the waterproof sheet material 10, in the example shown in the drawing, the waterproof sheet material 10 is fixed to the purlin 25 with a tacker T at appropriate positions of the uneven direction smooth portion 12 and the uneven direction orthogonal direction smooth portion 13. Since the uneven direction smooth portion 12 and the uneven direction orthogonal direction smooth portion 13 are formed in a smooth sheet shape, the closeness to the purlin 25 is good and easy to tackle. Moreover, since the uneven | corrugated direction smooth part 12 is formed at equal intervals with respect to the sheet | seat base material 10a, it can perform the tacker stop of equal intervals efficiently.

  Spacers 28 and 28 are disposed above the roof tiles 22 and 22 of the waterproof sheet material 10 attached in this way so as to fill a step with the roof 22 of the purlin 25 and further span the spacers 28 and 28. A waterproof tape 26 is attached to the roof tile 27 and a roof tile 27 is placed thereon.

  Thus, by using the waterproof sheet material 10 in the large ridge, the gap space S formed between the roof tiles 22 and 22 and the purlin 25 is blocked, and rainwater can be prevented from entering the gap space S. .

  Note that reference numeral 23 in FIG. 3 denotes a tile rail for placing the end portion of the tile, which is fixed on the base plate 21. Reference numeral 24 denotes support brackets that support the purlin 25 from below, and several things are fixed to the field board 21 along the longitudinal direction of the purlin 25.

The concave and convex strips 11a are in close contact with each other in a fan shape. In this case, it is desirable that at least the crown tile 30 is adhered by the adhesive layer 14.

Since the pressure-sensitive adhesive layer 14 is made of a butyl rubber system, it expands as the ridges 1 1 a develop, so that the waterproof sheet material 10 can be easily deformed and can be bonded even in such a deformed state. In order to ensure adhesion to 29, it is desirable to use the waterproof sheet material 10 in which the uneven direction pressure-sensitive adhesive layer 15 is formed on the uneven direction smooth portion 12 as shown in the figure. In the illustrated example, the waterproof sheet material 10 in which the pressure-sensitive adhesive layers 14 and 14 are provided at both ends and the uneven direction pressure-sensitive adhesive layer 15 is provided in each uneven direction smoothing portion 12 is used.

  In addition, as shown in the figure, the concave / convex orthogonal direction smoothing portion 13 of the waterproof sheet material 10 may be disposed at the corner portion of the butt portion of the end portion of the crown tile 30 to the wall 29, so that the waterproofing is achieved. The sheet material 10 can be easily folded, and the closeness to the wall 29 and the crown tile 30 is increased.

  The waterproof sheet material 10 is bent along the concave-convex orthogonal direction smoothing portion 13 so as to be curved and intimately contacted with the roof tile 22 and in close contact with the flat wall 29. . In this case, it is desirable that at least the roof tile 22 be adhered by the adhesive layer 14. Further, in order to ensure adhesion to the wall 29, it is desirable to use a waterproof sheet material in which an adhesive layer is also formed on the end portion on the wall 29 side.

  Moreover, the uneven | corrugated orthogonal | vertical orthogonal | vertical direction smooth part 13 of the waterproof sheet | seat material 10 should just be distribute | arranged to the corner part of the butt | matching part of the edge part 22 to the wall 29. Increased closeness to.

  As described above, the waterproof sheet material 10 adhered to the wall contact portion is provided with a waterproof finishing material (not shown) on the tile 22 side and an outer wall (not shown) on the wall 29 side. Hidden by that.

  As described above, the waterproof sheet material 10 prevents water from entering by sticking it to various objects and target locations. Other applicable locations include eaves, corner buildings, flow walls, valleys, and the like. Thus, in said embodiment, although it is suitable for the places which require bending, such as an entrance corner and an exit corner part, it can be used conveniently also for a flat part.
