Description

  The present invention relates to a bonding method in which an adhesive is applied to a planar exterior material to attach the exterior material to a wall surface. More specifically, the present invention relates to a method of installing a tunnel interior plate for attaching an interior plate installed for the purpose of safe traveling of a vehicle to a wall surface of a tunnel or the like. The present invention relates to a mechanized device and an adhesive application system for attaching a tunnel inner wall surface mounted on a vehicle.

  The planar exterior material is attached to various wall surfaces, so that the aesthetic appearance of the attached wall surface can be improved, and also the wall surface can be protected. Therefore, the exterior materials are variously installed for various purposes. The exterior materials can be broadly classified into exterior tiles and exterior materials.

In particular, when the wall is the inside of the tunnel, vehicles passing through the tunnel can travel safely and comfortably, such as improving the visibility of obstacles ahead, improving the appearance, improving the gaze guidance effect, and improving the lighting effect. For the purpose of being able to do so, an interior plate as the exterior material is provided. As a method of installing the interior board, there are a method using a metal fitting and a method using an adhesive, and the method using an adhesive is a standard method (for example, see Non-Patent Documents 1 and 2).
The Japan Highway Public Corporation “Design Guidelines, Third Collection, Tunnel”, revised version in October 1997, Japan Highway Welfare Association, published in February 1999 Kyushu Regional Development Bureau Planning Department, "Civil Engineering Design Guidelines (Part 3 Roads)", 19th revised edition, Kyushu Regional Planning Association, April 2001

  As the above-mentioned adhesive-stretching method, the interior wall of the tile of the interior board is cleaned, and then the inner wall of the tunnel is subjected to an underlying treatment, and then a primer is applied. After adjusting the unevenness of the inner wall surface of the tunnel to which the primer is applied, an adhesive is applied to the inner wall surface of the tunnel, and the interior plate is attached. As a method of applying the adhesive to the inner wall surface of the tunnel, the adhesive is mixed by hand with a hand mixer, and applied to the concrete surface, which is the inner wall of the tunnel, using a comb iron. The method of attaching the interior boards is done manually.

  In the above-mentioned adhesive-stretching method, a small porcelain tile having a size of 100 mm × 200 mm × 10 mm or 60 mm × 227 mm × 10 mm has been conventionally used as an interior board. However, in recent years, the size of the interior plate is 1000 mm × 250 mm × 6 mm because there are few scattered objects at the time of collision with a car, the number of on-site construction steps is small, the maintenance is easy, and the ratio of joints between the interior plates is small. Large porcelain tiles are used.

  The amount of the adhesive to be applied to the concrete surface largely depends on the experience and intuition of the worker, since the application amount is not constant and it is difficult to achieve uniform adhesion quality because the application is manual. However, in recent years, there is a shortage of skilled workers, and there is also a remarkable shortage of young workers, making it difficult to train skilled workers. Therefore, when a large-sized porcelain tile is used for the interior board, if the bonding quality is poor, the large board must be replaced, and the replacement work becomes large.

  When a two-part epoxy adhesive is used as the adhesive, a usable time of about one hour is set as the time from the completion of kneading the adhesive to the completion of the attachment of the interior board. In the above construction method, since the application of the adhesive and the bonding of the interior board are separate work knitting, there is a difference in the use time from the mixing of the adhesive to the completion of the bonding of the interior board, and the bonding quality varies. Easy to occur. In particular, if the attachment of the interior board is not completed within the usable time, adhesion failure occurs.

  Therefore, in order to reduce the variation in the bonding quality, it is necessary to equalize the time from the mixing of the adhesive to the completion of the bonding of the interior plate.

  Furthermore, in recent years, the average age of construction workers is aging, and the application of adhesives places a heavy burden on the arms, and causes a large amount of physical strength such as a large amount of bending and stretching of the hips and knees. In the above-mentioned adhesive-stretching method, construction is performed manually, and in particular, since the step of applying the adhesive is performed manually, there is a limit to the construction speed, which reduces the construction time and reduces the cost of the product. It is difficult to provide.

  In addition, the two-component epoxy adhesive contracts in volume with curing, so that stress is accumulated on the bonding surface. Since this stress tends to cause interface destruction on the bonding surface due to a synergistic effect with vibration caused by running of the vehicle and expansion and contraction due to a change in air temperature, it is preferable to disperse the contraction stress of the adhesive.

  Variations in the bonding quality, shortening of the construction time, and cost reduction as described above are issues not only in the method of attaching the interior plate to the inner wall surface of the tunnel, but also in the method of installing a planar exterior material. Become.

  An object of the present invention is to provide a method for installing a flat exterior material on a wall surface, to reduce unevenness in adhesion quality by equalizing the time from kneading of an adhesive to completion of attaching an interior plate, and to improve a construction speed. Accordingly, it is an object of the present invention to provide a method capable of shortening the construction time and providing a low-cost product.

  In particular, an object of the present invention is to provide a method for installing an interior board on the inner wall surface of a tunnel, to reduce the variation in adhesion quality by equalizing the time from kneading of the adhesive to completion of attaching the interior board, and to reduce the construction speed. An object of the present invention is to provide a construction method capable of shortening the construction time and providing a low-cost product by improving the construction.

Therefore, the present inventors have conducted intensive studies and found that the adhesive is applied to the rear surface of the planar exterior material at a predetermined interval by using an adhesive application device having a nozzle for applying spots, spots or lines. A method of installing an exterior material for applying the exterior material to a wall surface after application in a spot, spot shape or linear shape with a predetermined application amount, wherein the interval and the application amount are such that the interior plate has a thickness of 0. When applied in a tunnel at 98 kPa, adjacent adhesives are not connected to each other, and the total amount of the adhesive applied to the exterior material is 1.9 kg / m ² or more. By using the method of installing the exterior material, the time from mixing of the adhesive to the completion of the application of the exterior material can be made uniform. By improving the construction speed, the construction time can be shortened and low-cost products can be provided. To Found that can Rukoto, have completed the present invention. In particular, by using the installation method of the present invention for a method of installing an interior plate on the inner wall surface of a tunnel, the time from mixing of the adhesive to completion of the attachment of the tunnel interior plate can be made uniform, and the construction speed is improved. By doing so, it is possible to shorten the construction time and provide a low-cost product.

The present inventors also provide an adhesive supply device, a spot for applying a predetermined amount of adhesive at predetermined intervals, a nozzle for applying a spot and a line, and a roller for moving a planar exterior material. An adhesive application device provided with a spot, the exchange of the nozzle and the operation control of the supply device including the nozzle, spots a predetermined amount of adhesive at predetermined intervals on the object to be coated, spot shape and linear shape Means for applying, the interval and the amount of application are such that when the exterior material is affixed in a tunnel at 0.98 kPa, adjacent adhesives are not connected to each other, and the adhesive is by using an adhesive application device, characterized in that it is applied to the rear surface of the outer package 1.9 kg / m ² or more, found that can be easily applied with respect to the outer member to be pasted on the wall It has led the present invention. In particular, by using the adhesive application device for applying the adhesive to the back surface of the tunnel interior plate, the adhesive can be easily applied to the interior plate attached to the inner wall surface of the tunnel.

  Furthermore, the present inventors provide an interior plate holding region and an adhesive application device in a vehicle, and carry the interior plate into the adhesive application device from one side of the vehicle, and apply the adhesive. An adhesive-coated interior is used by using an adhesive application system for a tunnel interior plate in which the adhesive application device is installed in a vehicle so that the interior plate is carried out from the device to another side of the vehicle. The interior board can be stuck to the inner wall of the tunnel immediately after the adhesive is applied without the person carrying the board for a long distance, and the interior board coated with the adhesive is carried out to the sidewalk side. Since the adhesive application device can be moved in parallel with the plate attaching operation, the labor required for the operation is reduced, and the operation efficiency is good.

  By using the method for installing a tunnel interior board or the adhesive application device of the present invention, the amount of adhesive used becomes uniform for each interior board and the adhesive usage per interior board is reduced by 25%. As a result, resources can be saved and the effect of cost reduction can be obtained. Further, according to the present invention, by mechanizing the application of the adhesive, it is possible to accurately arrange the applied adhesive so that the contraction stress accompanying the curing of the adhesive is diffused, and the adhesive performance of the interior board is improved.

  Hereinafter, the present invention will be described with reference to the drawings, but the present invention is not limited thereto.

  Hereinafter, the present invention will be described by taking a tunnel interior plate as an example of an exterior material. However, in the present invention, the exterior material is not limited to the tunnel interior board according to the following description.

(How to install exterior materials)
The present invention provides an adhesive applying apparatus provided with a nozzle for applying a spot, a spot or a line, by applying an adhesive on a rear surface of a planar exterior material at a predetermined interval and a predetermined application amount, a spot, and a spot. The method for installing an exterior material, in which the exterior material is attached to a wall surface after being applied in a shape or a line, wherein the interval and the application amount are such that the interior plate is attached in a tunnel at 0.98 kPa. In such a case, there is a relationship in which adjacent adhesives are not connected to each other, and the total amount of the adhesive applied to the exterior material is 1.9 kg / m ² or more. In the present invention, the adhesive is applied in the form of a spot or a line, but the method of applying the adhesive in the form of spots or spots can easily apply the adhesive, and furthermore, the amount of the adhesive is reduced. It is preferable because it can be applied in a used amount. A similar effect can be obtained by applying the adhesive in a linear manner.

  FIG. 1 is a partially enlarged schematic view of an aspect in which an adhesive is applied in a spot shape to a tunnel interior board as an exterior material in the method for installing an exterior material of the present invention. FIG. 2 is a perspective view of the interior plate in which the adhesive spots are formed in the mode when the adhesive is applied in a spot shape to the tunnel interior plate of FIG. The adhesive is applied to the interior plate 1 by a discharge nozzle 4 of an adhesive application device provided with a nozzle for applying a spot shape, and a spot 2 of the adhesive is formed on the interior plate 1. After the adhesive is discharged from the discharge nozzle 4 in the form of a spot, the interior plate 1 is conveyed by the rollers 3 to form a spot 2 ′ adjacent to the spot 2. In FIG. 1, the discharge nozzles are arranged in tandem, and spots 2 are formed on the back surface 6 of the interior board as shown in FIG.

The spot distance d between adjacent adhesives is a relationship between a spot interval and a spot application amount such that adjacent adhesive spots are not connected to each other when the interior plate is attached to the inner wall surface of the tunnel at 0.98 kPa. Have. In addition, the total amount of the adhesive applied to the interior board is 1.9 kg / m ² or more in the case of an epoxy adhesive having a specific gravity of 1.67. If the amount of the adhesive spot is too large and the adhesive spots are attached to the inner wall surface of the tunnel and adjacent adhesive spots are connected to each other to cover the entire interior plate, the effect of the adhesive is As a result, the shrinkage stress generated increases, so that the adhesive strength of the interior plate to the inner wall surface of the tunnel decreases. If the gap between the adhesive spots is too wide and the glued adhesive spots are too wide between adjacent adhesive spots when they are pasted on the inner wall of the tunnel, The total amount of the adhesive applied to the resin decreases, and the adhesive strength decreases. That is, by applying an adhesive to the back surface of the exterior material so as to have the above-described relationship between the spot interval and the spot application amount, the interior board is forced to have a force of about 0.98 kPa (for example, 0.9 to 1 kPa). .1 kPa) or 0.98 kPa, the adhesive strength is not reduced even when pressed against the inner wall surface of the tunnel and applied. Further, similarly to the case where the adhesive is applied as the spot, the adhesive strength is not reduced even when the adhesive is applied in a spot shape or a linear shape.

  In the installation method of the present invention, when the adhesive is applied in a spot shape, the relationship between the spot interval and the spot application amount such that adjacent adhesive spots are not connected to each other is, for example, a dimension of 1000 mm (length) × 250 mm ( In the case of applying to an interior board of (width) × 6 mm (thickness), when the adhesive is spotted in the length direction so that an interval between the adhesive spots is equal to that in the width direction, when the adhesive is spotted in the width direction, By setting the 35 spots at equal intervals, the adhesive spot amount (spot application amount) per spot can be set to about 1.6 g. By setting a predetermined spot interval and a predetermined spot application amount such that adjacent adhesive spots are not connected to each other, the amount of the adhesive used in the installation method of the present invention becomes uniform for each interior plate and one sheet. Since the amount of adhesive used per interior board is reduced by 25%, it is possible to save resources and to obtain the effect of cost reduction.

The adhesive is not particularly limited as long as it has good adhesive strength and is suitable for bonding a tunnel interior plate, and is preferably a two-part epoxy adhesive, a two-part epoxy-urethane adhesive, or a two-part adhesive. A urethane-based adhesive, a one-pack type epoxy adhesive, a water-curable adhesive, or the like can be used. The adhesive is applied so that the spread adhesive spots do not come into contact with adjacent adhesive spots when the interior plate applied with the adhesive in the form of spots is attached to the inner wall surface of the tunnel. Preferably has a spot-like shape when applied to an interior plate, and has a viscosity of 120 × 10 ^{4 to} 160 × 10 ⁴ (measuring machine: BH-type rotational viscometer, measuring condition: 20 ° C.). Preferably, there is. Further, the total amount of the adhesive applied to the interior board is 1.9 kg / m ² or more when the epoxy adhesive has a specific gravity of 1.67, and for example, the specific gravity is changed to the epoxy adhesive. When a different adhesive is used, the adhesive can be applied so that the applied adhesive has a volume of 1138 cm ³ or more.

  When the adhesive is applied in the form of a spot, the spot of the adhesive applied to the interior board has a size of, for example, 1000 mm (length) × 200 mm (width) × 10 mm because the inner wall surface of the tunnel has a curvature. When the interior plate of thickness) is attached horizontally to the inner wall surface of the tunnel, the gap between the central portion of the interior plate and the inner wall surface of the tunnel is about 2 mm, so it is preferable to increase the coating amount of the spot near the central portion. . In order to improve the adhesive strength of the interior board to the inner wall surface of the tunnel near the center of the interior board, the height h of the adhesive spot is equal to the height of the adhesive spot at the end of the interior board in the width direction. On the other hand, the height is preferably 113 to 123%, more preferably 118%. Also, the height of the spot of the adhesive is adjusted in accordance with the curvature of the inner wall surface of the tunnel to improve the adhesive strength, and the locus of the apex of the spot of the adhesive in the width direction of the interior plate in the interior plate width is changed in the tunnel. Preferably, it is the same as the curvature of the wall. In addition, similarly to the case where the adhesive is applied in the form of spots or spots, when the adhesive is applied linearly, the height of the adhesive applied near the center portion is applied to the end portions. The height is preferably 113 to 123%, more preferably 118%, with respect to the height of the applied adhesive, and is applied in accordance with the curvature of the inner wall surface of the tunnel as described above. Preferably.

  In the installation method of the present invention, the size of the interior board is not particularly limited, but is preferably larger than an area of dimensions 1000 mm × 250 mm × 6 mm. Further, for example, an adhesive may be applied to a tile serving as an exterior material on a small tile having a length of 60 mm and a width of 227 mm by the above-described method, and the small tile may be combined and applied to an adhesive surface. This is because, when the size of the interior board is large, the effect of improving the working efficiency is more exhibited by the installation method of the present invention. The material of the interior plate is not particularly limited, but it is preferable that the interior plate is a non-combustible material such as ceramics, fiber reinforced cement plate, enameled metal plate, and aluminum metal plate to prevent generation of toxic gas in a tunnel fire. Ceramics are particularly preferable because they are excellent in durability represented by chemical resistance against exhaust gas inside the tunnel.
