Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a prefabricated waterproof material for rising portions, a method for manufacturing the same, and a structure of a joint portion using the same.

[0002]

2. Description of the Related Art The waterproofing method is (1) a asphalt waterproofing thermal method in which solid asphalt is melted in a pot at a construction site, and a plurality of asphalt roofing layers are laminated with the adhesive to form a waterproof layer, (2) Asphalt waterproof cooling method to form a waterproof layer by laminating multiple asphalt roofing with self-adhesive layer (self-adhesive layer), (3) Synthetic polymer sheet such as vulcanized rubber and vinyl chloride There are a sheet waterproofing method in which an adhesive agent is applied to both the ground surface to form a waterproof layer with only one sheet, and (4) a urethane coating film waterproofing method in which urethane coating material is applied and finished. In the waterproofing work, since there are almost no factors that hinder the behavior of the worker with respect to the flat surface portion, it is possible to carry out the work efficiently in each of the above-mentioned waterproofing methods, and moreover, a high working accuracy can be obtained.
Satisfactory waterproofing work is achieved both from the waterproof side and from the finished side.

However, since the rising part is constructed from the flat part to the vertical part, it is very difficult to work, and its working efficiency is reduced to 1/3 to 1/5 of the working efficiency of the flat part.

In the case of the asphalt waterproof thermal method, it is necessary to have a great deal of skill to laminate a plurality of asphalt roofing sheets on a vertical surface while flowing a high temperature asphalt, but this technique has been acquired. The absolute number of technicians themselves has decreased sharply, which is a serious problem. In addition, the finished asphalt roofing surface is often contaminated with the asphalt used in the heat process, which poses a problem in terms of finish.

Since the asphalt roofing with a self-adhesive layer and the synthetic polymer roofing are also relatively flexible, the shape retention cannot be said to be sufficient, and a relatively high-level construction technique is required when applying the portion.

Due to such poor workability due to the rising surface, waterproofing of the rising portion cannot always obtain sufficient construction accuracy, and an incomplete waterproof portion is apt to occur.
Above all, since the seat waterproofing is a single layer waterproofing, water leakage accidents frequently occur at the rising part.

[0007] Regarding waterproofing of the coating film, it requires a considerable amount of skill to repeat the work of applying it to the vertical surface twice, and since the coating film has a self-leveling property in the flat portion, a waterproof layer having a smooth and uniform thickness can be obtained. However, it is difficult to obtain a smooth waterproof layer having a uniform thickness on a vertical surface unless the brush application technique is excellent.

In the case of a roofing with a self-adhesive layer or a synthetic polymer sheet, if the groundwork is finished accurately, the sheet cut according to the rising height can be attached horizontally for a long time to improve the construction efficiency. It also reduces the waterproof reliability. However, in reality, the base is considerably uneven, and wrinkles occur in the middle of the sheet due to the unsuitability of the sheet at the corners, etc. Therefore, it can be applied only at a length of about 2 m at most.

As described above, there are many problems peculiar to the rising portion, the work efficiency is remarkably reduced, and the worker needs a high degree of skill. In addition, the worker is physically tired. Furthermore, the decrease in the number of skilled workers is also a big problem, and in particular, there is a strong demand for simplification of the construction of the rising part of the asphalt waterproof thermal method-prefabrication.

Therefore, the present inventors have previously proposed Japanese Patent Application No. 7-9.

(4) An invention relating to a prefabricated waterproof material for a rising portion, characterized in that it comprises a peeling layer which covers the self-adhesive layer of the first waterproof layer in which the chamfering member does not exist. The present invention intends to utilize a prefabricated waterproof material for a rising portion, which is obtained by previously bonding two waterproof sheets [(1) and (2)] at a factory.

Further, in the second invention of the above-mentioned application, both end portions orthogonal to the chamfering member are provided with an area (a) of only the first waterproof layer with a constant width, and one end portion parallel to the chamfering member is provided. For the rising portion, which is provided with a region (b) of only the first waterproof layer having a constant width and a region (c) having no mineral grain layer of a constant width in the second waterproof layer adjacent to the region. We also proposed a prefabricated waterproof material, which also designed the joint to have double waterproof layers.

In the above-mentioned invention, the working time was shortened to 1/3 to 1/4 in the actual construction and was highly evaluated.
(A) A step of separately attaching two waterproof sheets is required, (b) height of rising part (usually 20 to 80 cm)
It is necessary to prepare at least 3 to 4 kinds of materials corresponding to the above, and the layer structure is complicated, so that the manufacturing cost is inevitably high.

Structure of the joint portion to be related.

As the mineral particle layer, not only sand particles that are commonly used for the surface layer of asphalt roofing but also particles or powders of minerals such as silica, silica sand, mica, clay and alumina can be used. There is no limit.

Examples of the metal foil layer include aluminum foil and copper foil, and examples of the weather resistant synthetic resin in the weather resistant synthetic resin film layer include polyolefins, polyesters, polyamides and acrylic resins. The film formed of these may be a stretched film or a non-stretched film, and the thickness thereof is not particularly limited, but is generally 8 to 30 μm.
m.

As the base material in the joint auxiliary member and the finish material for the joint portion and the first base material layer in the prefabricated waterproof material for the rising portion, any one can be used as long as it is used for ordinary asphalt roofing. In general, the base material layer can use any base material such as cloth, non-woven fabric, and film, and examples thereof include woven and non-woven fabrics made of natural fibers and synthetic fibers, and plastic films. The second base material layer in the prefabricated waterproof material for the rising portion is preferably soft and excellent in flexibility, and may be a synthetic resin film, but a relatively thin synthetic resin nonwoven fabric or woven cloth is coated with the synthetic resin. Those are particularly preferable. Due to the presence of the synthetic resin layer, there is no problem of blocking even if the second base material layer is exposed as shown in FIG. 4 (usually, asphalt roofing base material is impregnated with asphalt, so that it is exposed as it is. Even if you try to use it, it sticks to other things in a sticky state and causes blocking, so it cannot be used practically).

As the adhesive layer, any material can be used as long as it has an affinity for the asphalt layer as well as an affinity for concrete and mortar, and exhibits self-adhesiveness to it, but rubber-modified asphalt is particularly preferable. preferable. Further, a tackifier or an oil component may be added to the adhesive layer as needed.

Preferred composition examples of the adhesive layer are shown below. This adhesive layer was comparable to the adhesive by the hot asphalt method in terms of adhesive strength and durability. SBS * 1 10 to 20 parts by weight eg 15 parts by weight Asphalt 60 to 70 parts by weight eg 65 parts by weight Tackifier * 2 5 to 15 parts by weight eg 10 parts by weight Process oil 5 to 15 parts by weight eg 10 parts by weight * 1; SBS is a styrene / butadiene block copolymer. * 2: The tackifier is a polymer or copolymer of a C ₅ and / or C ₉ unsaturated fraction.

Blown asphalt or modified asphalt can be used as the asphalt applied to the joint portion.

The release layer is usually release paper, but any material that does not have an affinity for the adhesive layer can be used.

The synthetic resin film used for the layer construction of the joint auxiliary member and the joint part finishing material is polyethylene,
Polyolefin such as polypropylene, polyester,
It may be a film of polyamide or the like, but it is preferable to apply a coating film having a high affinity to both the synthetic resin film and the asphalt on the surface that comes into contact with the asphalt. Such coating film forming materials include urethane-based, acrylic urethane-based, acrylic-based, polyamide-based,
A polyester-based paint or the like can be used. In short, this coating layer is such that when a force is applied to forcibly separate the synthetic resin film layer and the asphalt layer, the adhesive force is exerted so that the synthetic resin film layer or the asphalt layer is destroyed. It is sufficient if it is of a nature, and when there is such adhesive strength, the asphalt layer usually causes cohesive failure when forcibly peeling the two, so that the required adhesive strength is obtained. It is possible to determine whether it is being exerted. The thickness is preferably about 5 to 30 μm. Examples of the coating film forming paint include the following. NB 300 RS-2 (Dainichi Seika, trade name) 100 parts by weight Lamic B Hardener (Dainichi Seika, trade name) 5 parts by weight Lamic F (solvent) (Dainichi Seika, trade name) 50 parts by weight

As shown in FIG. 7, the chamfering member 28 is used in conformity with the corner portion 10 between the rising portion 8 and the floor surface 9, and is a columnar member having a cross section of an isosceles right triangle or a trapezoid, and is commonly used as a cant. Sometimes called a strip.
Examples of the material include plastics, foamed plastics, wood, and the like, and foamed plastics are preferable from the viewpoint of reducing the overall weight. From a manufacturing standpoint, rigid polyurethane foam is most convenient.

When the prefabricated waterproof material for rising portions is manufactured by the method according to claim 4, the direction perpendicular to the longitudinal direction of the waterproof composite long sheet is the prefabricated waterproof material for rising portions according to claim 1 of the present invention. It corresponds to the vertical direction of the material. This vertical length is the distance from the A position to the B position as seen in FIG. 7, and since this distance is determined by the manufacturing apparatus for the waterproof composite long sheet, it is constant when only the specific apparatus is used. There is a constraint that only distances can be manufactured.

Therefore, according to the method of claim 4 of the present invention, the cant setting place is not provided in the central portion of the waterproof composite long sheet, but is shifted to the right or left at a ratio of 6: 4 or 7: 3, for example. If it is installed at a different position, the width of the long sheet is 100c.
When using a device that can only manufacture m, the chamfered member 28 in the completed prefabricated waterproof material for the rising portion 28
Seen from the center line of, one with 60 cm and the other with 40 cm, and one with 70 cm and the other with 30 cm are obtained. 60 cm on one side and 40 cm on the other side is 60
If used with the cm side facing up, it can be used for heights of 60 cm (see the description on the right side of FIGS. 1 and 2), 4
When used with the 0 cm side facing upward, it can be used for a height of 40 cm (see the description on the left side of FIGS. 1 and 2). If one is 70 cm and the other is 30 cm, the height will be 70 cm if the 70 cm side is used upward.
It can be used as a product for a height of 30 cm if the 30 cm side is oriented upward. As described above, the prefabricated waterproof material for the rising portion of the present invention can be used as a prefabricated waterproof material for the rising portion capable of supporting another height by reversing the vertical direction. Therefore, the prefabricated waterproof material 2 for the rising portion of the present invention 2 As a result of manufacturing the types, substantially four types of prefabricated waterproof materials for rising portions are manufactured.

When the prefabricated waterproof material for rising portions is manufactured by the method according to claim 5, the longitudinal direction of the waterproof composite long sheet corresponds to the vertical direction of the prefabricated waterproof material for rising portions according to claim 2 of the present invention. Therefore, in this case, any length in the vertical direction can theoretically be supplied if necessary. However, preparing too many different sizes will result in cost increase. Therefore, if the prefabricated waterproof material for the rising portion of the present invention is turned upside down as described above, another height is obtained. By taking advantage of the structure that can be used as a thing, by flipping the top and bottom, one prefabricated waterproof material for rising part can be used as a prefabricated waterproof material with two kinds of rising part height. Therefore, it is industrially important to install the chamfering member in a position where the lengths of the rising surface bonding surface and the floor bonding surface are not the same.

Example 1 In both the type of claim 1 and the type of claim 2, as the weather resistant surface layer, sand grains which are usually used as the surface layer of asphalt roofing were used. Polyethylene terephthalate nonwoven fabric (trade name polyester spun bond) was used for the first base material layer and the second base material layer.
However, only the second base material layer of the type of claim 2 was one in which polyethylene was thinly extruded and laminated on both surfaces of the spunbond. The composition for forming the pressure-sensitive adhesive layer consisted of SBS 15 parts by weight Asphalt 65 parts by weight C ₅ Petroleum fraction polymer (tackifier) 10 parts by weight Process oil 10 parts by weight. The total thickness of both types of claims 1 and 2 in this embodiment is 3.8 m.
