Description of the Related Art As an exterior construction of a building, after laying a board-shaped exterior member such as concrete, waterproofness is given to joints which are gaps or gaps formed in adjacent portions of the exterior members. Joint waterproofing is performed to improve the appearance. As the joint waterproofing construction, there are a wet construction method in which the joint material is filled with a liquid or paste sealant, and a dry construction method in which a molded product of EPDM rubber or PVC resin is fitted into the joint, and either one is selected depending on the construction conditions. The construction method of is adopted. In practice, most of them are constructed by the wet method.

比べて実用性に劣るとされている。Among the conventional joint waterproofing methods, the wet method has a problem that the number of construction steps is increased and the work is troublesome. In the wet method, it is necessary to perform many steps such as masking, bond breaker, primer, sealant filling, sealant leveling, and masking removal to avoid soiling the surrounding area with a sealant, which is troublesome. At the same time, technically difficult work is required. With the dry method, it is difficult to deal with variations in joint width. In the usual construction of the exterior member, the joint width inevitably varies greatly. In a joint member formed in advance to a certain size, there is often a gap between the joint member and a joint having a large variation, or conversely, it becomes difficult to fit the joint member. Therefore, it is said to be inferior in practicality as compared with the wet method.

The exterior member has a board shape such as a rectangular shape such as a decorative concrete plate, and the exterior surface is formed by laying the exterior member on the surface of a basic structure of a wall surface made of reinforced concrete or the like. A gap or joint having a certain width is provided at the joint of the exterior members, and the joint is provided with a waterproof function or a sealing function, thereby improving the waterproof property or the seal property at the joint between the exterior members and the appearance design effect. Can also have. By providing the joint, it is possible to absorb the dimensional error between the exterior members and the deformation due to the load.

ィルムやシートを積層しておくこともできる。The width and depth of the joint are determined by the size and arrangement structure of the exterior member, or the function required for the joint. A joint material is used for finishing construction of such joints and is inserted into the joints. The joint material includes an adhesive waterproof material, a strip plate material and a release sheet. [Adhesive Waterproof Material] The same material as a waterproof material having a normal adhesive property is used. It is preferable to have adhesiveness that can be firmly adhered to the inner surface of the joint and flexibility that can be deformed along the inner surface of the joint. Specifically, a rubber material such as butyl rubber or a synthetic resin material is used. A non-woven fabric may be embedded in the adhesive waterproof material, or a film or sheet made of synthetic resin such as polyethylene or rubber may be laminated on the surface not sticking to the joint.

〜１２mmに設定することが好ましい。The width of the adhesive waterproof material is a little wider than the width of the bottom surface of the joint, and it is preferable that the adhesive waterproof material has a width that can be attached to a part of the inner side surface from the bottom surface of the joint. In particular, if it is adhered to the inner surface of the joint with a sufficient width, the waterproof function or the joint protection function is remarkably improved. The thickness of the adhesive waterproof material is determined in consideration of the fact that the waterproof function and the protective function can be sufficiently exerted and the deformation along the joint is easy. Specifically, for example, when the joint width is 10 ± 2 mm, the width of the adhesive waterproof material can be set to 16 to 22 mm and the thickness can be set to 0.3 to 1.0 mm, although it depends on the structure of the joint to be constructed. . The difference between the width of the adhesive waterproof material and the inner width of the joint is 6
It is preferable to set it to -12 mm.

Self-sustainability means that the strip-shaped material that is normally handled has a shape-retaining property such that it can be maintained in a substantially flat state without folding or drooping when placed in a horizontal or vertical posture. Means that Specifically, it is preferable that even a band material having a size of several tens of cm exhibits self-supporting property. Specific materials include relatively hard synthetic resins such as polystyrene, polypropylene, and polyvinyl chloride, metals, ceramics, wood materials, and the like.
A highly deformable soft synthetic resin foam or the like is not preferable because it has no self-supporting property. As the strip material, one having waterproofness, fire resistance, heat insulation, and other functions required for a building structure is preferable.

る。If the width of the strip material is narrower than the width of the adhesive waterproof material and slightly smaller than the inner width of the joint, it is easy to arrange a part of the adhesive waterproof material along the inner side surface of the joint. become. As a specific dimension of the strip material, for example, the joint width is 10 ±
In the case of 2 mm, the width of the strip plate material can be set to 6 to 7 mm and the thickness can be set to about 1 to 3 mm. The difference between the inner width of the joint and the width of the strip material is preferably set to 3 to 4 mm. [Concave groove] It is arranged on the surface of the strip material so as to extend in the longitudinal direction. A plurality of concave grooves are arranged side by side in the width direction of the strip material.

なるという利点もある。The size and shape of the concave groove are set so that the pressing work of the joint material by the pressing tool described later can be easily performed. Specifically, the width can be set in the range of 1 to 5 mm and the depth in the range of 0.1 to 0.5 mm. The number of recessed grooves varies depending on the conditions such as the width of the strip plate material and the width of the pressing tool, but normally about 1 to 3 grooves are provided. The concave groove may be formed by recessing on the flat surface of the strip material, or by disposing a plurality of longitudinal strips extending in the longitudinal direction on the flat surface of the strip material at intervals, The space can be used as a groove. It is easier to form and manufacture the strip material when the groove is formed by the ridge. Further, as compared with a strip plate material having a flat surface, a strip material having ridges on the surface has an advantage that shape retention or self-supporting property is higher.

く。The dimensional shape of the ridges may be set so that the dimensional shape of the above-mentioned concave groove can be configured. As the shape of the ridge, a semicircular cross section, a semi-elliptical shape, an ellipse, a rectangle, a triangle or the like can be adopted. The width of the ridge can be set in the range of 0.2 to 2 mm. The number of ridges is one more than the number of concave grooves to be formed. [Release Sheet] An ordinary release sheet for protecting the adhesive material is used. The release sheet is a PET resin sheet,
It is made of paper or the like, and if necessary, a release agent made of silicon or the like is applied to the surface to improve the releasability.

いは帯板材の幅と同じ程度に設定しておくのが好まし
い。At least the surface of the release sheet to be adhered to the adhesive / waterproof material must have releasability. When the joint material is stored in piles, or when the release sheet protects not only the back surface but also the surface of the adhesive waterproof material, it is preferable to provide release properties to both sides of the release sheet. If a release agent is applied to the surface of the release sheet, when the joint material is inserted into the joint, when the release sheet comes into contact with the inner surface of the joint, the release sheet becomes slippery and easy to insert. There is also an advantage that you can. Such a release sheet constitutes the center piece and the side pieces. The central piece is attached to an adhesive waterproof material during handling such as transportation and storage, but is peeled and removed before finishing the joint. The width of the central piece is preferably set to be approximately the same as the inner width of the joint or the width of the strip material.

ておくことができる。The side pieces are peeled off from the adhesive waterproof material before finishing the joint. The length of the part of the side piece that extends outside the side edge of the adhesive waterproof material is set to such an extent that it is easy to remove the side piece from the adhesive waterproof material after attaching the joint material inside the joint. I'll do it. Specifically, with the joint material attached inside the joint, part of the side piece protrudes into the space above the joint so that the operator can handle the protruding portion. The central piece and the side piece may be formed separately in advance, but can be integrally formed in a state of being separably connected via a perforation line or a weakening line.

1 ~ 0.3mm, width of the central piece is 5 ~ 7mm, width of the side piece is 2
It can be set to about 5 to 31 mm. The difference between the inner width of the joint and the width of the center piece is preferably set to 0 to 2 mm. It is preferable to set the difference between the total width of the width of the central piece and the width of the side piece and the total width of the inner width of the joint and the thickness of the left and right exterior materials to 20 to 40 mm. [Non-adhesive layer] Makes it difficult for dust, foreign matter, and the like to adhere to the surface of the adhesive waterproof material where the strip material is not arranged. It is possible to prevent other members from sticking to the surface of the adhesive / waterproof material and making the handling difficult during the handling and construction work of the joint material.

The non-adhesive layer preferably has flexibility so that it can be easily deformed like the adhesive waterproof material. The non-adhesive layer can be laminated simultaneously with the production of the adhesive waterproof material. It is also possible to form a coating on the surface of an adhesive waterproof material manufactured in advance or to attach a non-adhesive film molded in advance. The non-adhesive layer can be placed on the entire surface of the adhesive waterproof material, or can be placed only on the portion of the adhesive waterproof material outside the location where the strip plate material is placed.

〔目地防水工法〕前記した目地材を用いて、建築物の外
装面に形成された目地の防水工法が行われる。When the non-adhesive layer is arranged on the entire surface of the adhesive waterproof material, the strip material is bonded onto the non-adhesive layer. When the band plate material is directly bonded onto the adhesive waterproof material, the band material is bonded by the adhesiveness of the adhesive waterproof material without any special bonding means. However, when joining the strip plate material to the surface of the adhesive waterproof material via the non-adhesive layer, a means for joining the non-adhesive layer and the strip plate material is required. Specifically, various adhesives and pressure-sensitive adhesives can be used. Bonding by heat fusion can also be applied. A double-sided adhesive layer such as a double-sided adhesive tape may be arranged between the non-adhesive layer and the strip plate material. [Sealing Waterproofing Method] A waterproofing method for a joint formed on the exterior surface of a building is performed using the above-described joint material.

It is preferable that the removal work of the central piece is performed immediately before the joint material is inserted into the joint so that foreign matter such as dust is not attached to the adhesive waterproof material as much as possible. With respect to a long joint material, it is possible to sequentially peel off only the central piece of the portion fed into the joint while feeding one end into the joint. Step (b): The joint material from which the central piece has been removed is inserted into the joint, the exposed surface of the adhesive waterproof material is attached to the bottom surface of the joint, and the side piece of the release sheet of the adhesive waterproof material is attached. The part is arranged along the inner surface from the bottom of the joint, and the side end of the side piece is arranged to extend outside the joint.

れる。Since the joint material has a self-supporting strip plate material, the joint material may be bent in the middle even if it is a joint extending to a vertical surface or a joint extending for a long time. Instead, the joint material can be inserted inside the joint and arranged in an appropriate posture. When the adhesive waterproof material is inserted into the joint having a narrow width, the flexible adhesive waterproof material is bent upward at the side end of the strip plate material having the shape-retaining property arranged above the flexible adhesive waterproof material and inserted into the joint. The bent portion of the adhesive waterproof material and the side piece of the release sheet attached thereto are arranged so as to extend upward along the inner side surface of the joint.

したりシワがよったりすることが阻止される。Since the side piece of the release sheet is attached to the rear surface of the adhesive waterproof material outside the portion attached to the bottom surface, the adhesive waterproof material does not adhere to the inner surface of the joint. , The adhesive waterproof material can be easily inserted up to the bottom surface of the joint. If the surface of the side piece is slippery, the joint material slides against the inner surface of the joint and can be inserted smoothly to the back. Step (c): The pressing tool is inserted into the concave groove on the surface of the strip material and moved along the concave groove, and the adhesive waterproof material is pressed against the bottom surface of the joint through the strip material. In order to surely attach the adhesive waterproof material to the bottom surface of the joint, it is effective to press the upper surface of the strip material downward. A pressing member having a rod shape, a roller shape, a spatula shape, or the like can be used to press the strip plate material inside the joint. By pressing the strip material, it is possible to prevent the pressing tool or the hand of the operator from adhering to the adhesive waterproof material or excessively distorting the adhesive waterproof material. The adhesive waterproof material can be strongly pressed and adhered to the entire flat bottom surface of the joint with the flat lower surface of the strip material. The adhesive waterproofing material integrated with the strip plate is prevented from being deformed or wrinkled.

り引っ張ったりする操作が行い易い。By moving the retainer along the groove, both sides of the retainer can be smoothly moved by being guided by the inner surfaces of the groove. If the pressing tool is simply pressed against the flat surface of the strip material inside the joint, the pressing tool easily slips off on the surface of the strip material, but if it is guided by the groove, the pressing tool is removed from the strip material. It can be prevented from coming off, and a sufficient pressing force can be surely applied. Step (d): The left and right side pieces of the release sheet are peeled off from the back surface of the adhesive waterproof material. The side piece is removed from the portion of the adhesive waterproof material arranged along the inner surface of the joint. At this time,
If the flexible adhesive waterproof material is slightly bent to the center side of the joint, the side piece removal operation becomes easy. If the tip of the side piece extends to the outside of the joint, the operator can easily carry out the operation of holding or pulling the side piece.

る。Step (e): The adhesive waterproof material from which the side pieces have been removed is attached by pressing it from the bottom surface of the joint to the inner surface. Since the range from the bottom surface of the joint to the exterior material existing on both sides of the joint is surely covered with the adhesive waterproof material, the waterproof function or the protective function of the joint is greatly improved. Even if there is an error in the inner width of the joint or the joint material mounting position is slightly shifted to the left or right, it is possible to prevent the bottom surface of the joint and the corners of the bottom surface from being exposed. Also in this step (e), it is effective to use the above-mentioned pressing tool to press the adhesive waterproof material against the joint so that the adhesive waterproof material is brought into close contact with no space. At this time, if the non-adhesive layer is arranged on the surface of the adhesive waterproof material, the pressing tool can be smoothly moved on the surface of the adhesive waterproof material on which the non-adhesive layer is arranged. Further, by further pressing the adhesive waterproof material against the bottom surface of the joint with the pressing tool via the strip plate material, the adhesive waterproof material can be reliably attached from the bottom surface of the joint to both side surfaces.

護を果たす。As a waterproof construction for joints, a finish construction can be completed by further combining a gasket, a sealant agent and the like described below. By performing the double waterproofing such as the waterproofing with the joint material of the present invention and the waterproofing with the gasket or the sealant, the waterproof function of the joint can be remarkably improved. Since the joint material of the present invention does not require a large space, it is thin (for example, 18 mm or less).
It is possible to apply the double waterproofing to shallow joints provided on the exterior member. Step (f): Install a gasket on the joint material inside the joint. As the gasket, various ordinary gaskets that are also used in the conventional joint finish construction can be used. The gasket is made of rubber, synthetic resin, fiber material, or the like, and has elastic deformability. The gasket is elastically deformed and inserted into the joint, and the elastic repulsive force of the gasket closes the gap between the gasket and the joint to waterproof or protect the joint.

減らすことができる。When the gasket is attached, the joint has a space above which the joint material is attached so that the gasket can be attached. Since the adhesive waterproof material and the strip plate material that constitute the joint material are thin, a sufficient space can be secured in the upper part of the joint. In addition, in order to expand the mounting space for the gasket, it is possible to remove the strip material from the adhesive waterproof material after the joint material is applied. Step (g): Filling the sealant agent on the joint material inside the joint. As the sealant agent, various ordinary sealant agents that are also used in the conventional joint finish construction can be used. By filling the sealant on the joint material, the waterproof function or the protective function of the joint can be further enhanced. Since the joint material is sufficiently waterproof and protected at the bottom of the joint, it is not necessary to use nerves to securely fill the bottom of the joint with the sealant as in the past, and it is relatively easy. Sufficient functions can be achieved even with simple filling work. Moreover, the filling amount of the sealant agent can be reduced.

There are few obstacles for insertion. As shown in FIG. 5, the left and right side pieces 34 of the release sheet are peeled off from the adhesive waterproof material 22. At this time, the joint 46
If the adhesive waterproof material 22 and the side piece 34 along the inner surface of the side piece 34 are bent so as to be slightly inclined from the inner side, the peeling work of the side piece 34 becomes easier. As shown in FIG. 6, the adhesive waterproof material 22 in the portion where the side pieces 34 are removed is pressed from the bottom surface of the joint 46 to the inner side surface so as to be firmly attached. At this time, using the spatula-shaped retainer 50, the adhesive waterproof material 2
2 is pressed against the entire bottom surface and inner side surface of the joint 46 without any gap. Since the non-adhesive layer 28 is provided on the surface of the adhesive waterproof material 22, the pressing tool 50 is attached to the adhesive waterproof material 22.
With the adhesiveness, the surface of the non-adhesive layer 28 can be smoothly slid and moved without sticking or being caught. By making the width of the strip material 24 a little smaller than the inner width of the joint 46, the pressing tool 50 can be easily inserted into the gap between the strip material 24 and the adhesive waterproof material 22.

It is fixed in close contact with 6. In this way, if the adhesive waterproof material 22 is attached to the bottom surface and the inner side surface of the joint 46, the joint waterproofing construction by the joint material 10 is completed without completion. Even in this state, the joint member 10 can perform the waterproof function and the protective function of the joint 46, but the following steps are performed in order to further improve the waterproof function and the appearance. [Gasket] As shown in FIG. 8, a gasket 60 is attached to the joint 46 to which the joint material 10 has been applied.

It is made of a molded product of PDM rubber or PVC resin, and is provided with fin-like pieces 62 that are entirely belt-shaped and project to the left and right. When the gasket 60 is pushed into the space above the joint material 10 in the joint 46, the fin-shaped piece 62 is elastically deformed and mounted. Due to the elasticity of the gasket 60, the fin-shaped piece 62 is strongly pressed against the inner surface of the joint 46, and the internal space of the joint 46 is sealed. As a result, the joint 46 is protected by both the protective function of the gasket 60 and the protective function of the joint material 10 having the adhesive waterproof material 22, and has a practically sufficient protective function such as waterproofness.

件で施工される。The joint waterproofing construction using the joint material 10 and the gasket 60 is a so-called dry construction and does not use a liquid filler, so that the construction is simple and the construction is completed in a short time. [Sealant] In the embodiment shown in FIG. 9, the joint material 10 is applied to the joint 46 and then the sealant 70 is filled. The sealant 70 is a material used for ordinary joint construction, and is applied under the same procedure and processing conditions as in the ordinary joint construction method.

In addition, when the joint construction is performed only with the sealant agent 70, the sealant agent 70 needs to be reliably filled into the entire joint 46 without any gap, which makes the work difficult and labor-intensive, but the joint material 10 protects the joint. If the function is sufficiently exerted, the construction conditions of the sealant agent 70 are not so difficult and can be performed relatively easily. Joint material 10

After filling with 0, a gasket 60 can be inserted over it. In this case, the surface of the sealant agent 70 does not need to be finished so beautifully, so the labor of the work can be saved. Further, when the joints 46 are arranged vertically and horizontally in a lattice pattern, basically, the finishing work is performed by the gasket 60, and in a place where a joint or a gap is likely to be formed in the linear gasket 60 such as an intersection of the lattice, By filling the sealant 70, the joint 46 can be surely protected.
