DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seat panel mounting method and a mounting structure. More specifically, the present invention relates to a method of attaching a plastic sheet panel, which cannot be bonded with an adhesive such as an epoxy resin type, a urethane resin type, or an acrylic resin type, to the surface of concrete, ceramic, metal or wood. These seat panels are made of corrosion-resistant materials
It is used as an anticorrosion material, especially for lining concrete or metal water tanks, waterproofing lining for basements and underground garages, protecting the inner surfaces of tunnels and seawalls, and protecting the outer walls of various buildings.

[0002]

2. Description of the Related Art A sheet panel made of plastic such as polyvinyl chloride, polypropylene or polyethylene is mechanically mounted on a concrete surface because the above-mentioned adhesive does not work. For example, when a sheet panel is attached to a concrete surface in advance, as shown in FIG. 13, a projection 51 for an anchor is integrally formed on the concrete surface side of the sheet panel 50, and a screw 53 and a nut are attached to a formwork 52. 54, or using nails or double-sided adhesive tape, and then concrete 55 is poured in, and after the concrete has hardened, the form is removed. FIG.
In the figure, reference numeral 56 is a so-called separator, 57 is a fastener, and 58 is a joint between adjacent sheet panels. The joint 58 may be filled with a joint material.

When retrofitting an existing concrete surface, a concrete anchor 60 is embedded in the concrete 55 in advance as shown in FIG. 14, and a putty-like adhesive 61 is provided on the surface of the concrete 55 as a gap filling material. The sheet panel 63 having the holes 62 is applied thereon, and the seat panel 65 is attached by screwing the anchor bolt 64 into the concrete anchor 60. Further, as shown in FIG.
5 are integrally provided with key-shaped projections 66, and washers 67 fitted to the projections 66 at predetermined positions on the concrete surface.
(See FIG. 16) using a concrete anchor 60 and an anchor bolt 64 to attach a seat panel 65.
The projection 66 is pushed into the washer 67 to be fitted therein, and the gap between the sheet panel 65 and the concrete 55 is injected and filled with a cement slurry 68 and fixed.

[0004] In the above-mentioned pre-installation method (Fig. 13), it is necessary to provide a projection 51 for a concrete anchor on a sheet panel, and since it is pre-installation, it cannot be used for repairing an existing concrete wall or the like. Limited. On the other hand, the conventional method (FIGS. 14 and 15) of mounting on an existing concrete wall requires a lot of concrete anchors and the like, so that the construction is difficult. In particular, the method using the washer 67 requires a difficult forming process of providing a key-shaped protrusion on the seat panel, and further requires the use of a special washer. Further, it is necessary to inject and fill a cement slurry or the like into the gap. Therefore, the material cost and the operation cost are high, and it is not economical.

On the other hand, if the purpose of mounting the seat panel is to block the outside air or waterproof, and the seat panel is used as a material for thickening the coating material, the filler is covered with the sheet panel. Even with the conventional method, there is no problem in terms of function (however, it is not economical in terms of cost). However, when it is desired to function as a corrosion-resistant or anti-corrosion material for chemicals, etc., the gap material such as cement slurry is exposed on the surface at the joint of the abutting portion of the sheet panel, so that the corrosion resistance is insufficient. . That is, as time passes, the joints are corroded by water and chemicals, and eventually the concrete inside is eroded.

[0006]

According to the present invention, there is basically no need to use a concrete anchor, a flat sheet panel having no projection can be adopted, and the sheet panel can be easily mounted on a concrete wall or the like by retrofitting. The technical problem is to provide a seat panel mounting method and a mounting structure that can be rational for the purpose of use, simplify the complicated steps of the conventional method, and provide a cost-effective method. To contribute to the maintenance and conservation of social capital.

[0007]

According to the method of mounting a seat panel of the present invention, an adhesive having an adhesive action on a mounting surface of a structure or the like and having a hardening property after bonding is applied to a mounting surface of a structure or the like. on the surface before the adhesive that, by pressing a sheet panels having a surface side is greater through-hole from the back side is introduced into the through hole, the adhesive on the surface side of the seat panel overflowing
For the protruding through holes, apply the adhesive to the surface of the sheet panel.
It is characterized in that it is finished to be flush with the surface, and then the adhesive is cured. In such a method, after the sheet panel is pressed against the surface of the adhesive and the adhesive is introduced into the through hole, the adhesive is introduced into the through hole that is not filled with the adhesive.
With, preferably fill the additional adhesive from the surface side to the rest of the cavity of the through hole.

[0008] A second method of the present invention is to provide an adhesive effect on a mounting surface of a structure or the like , and after bonding.
Apply the adhesive that cures to the surface of the adhesive before curing
In addition, several sheets with through holes with the front side larger than the back side
Press the sheet panel to introduce adhesive into the through hole
Then, by curing the adhesive , a plurality of sheet panels are aligned and attached, and then a second layer is provided on the surface of the sheet panels at a position covering the through holes and joints of the sheet panels. It is characterized in that the sheet panels are overlapped and bonded between the two sheet panels with an adhesive having an adhesive action. Note that the joint here is not limited to a joint formed particularly with a gap, but also means a seam between closely adjacent sheet panels. After attaching the second-layer sheet panels, a third-layer sheet panel is further superimposed on the surface of the second-layer sheet panels at a position covering the joints of the second-layer sheet panels. It may be made to adhere with an agent. In those cases, it is preferable to seal the intersection of the joints of the lower layer and the upper layer by welding.

First of the seat panel mounting structure of the present invention
The aspect of the present invention comprises a structure, a sheet panel attached to the surface of the structure, and an adhesive interposed therebetween, wherein the sheet panel has a stepped surface having a larger diameter on the front side than the diameter on the back side . Having a through-hole, the adhesive being filled into the through-hole so as not to protrude from the surface of the sheet panel, and being cured integrally with the adhesive on the back side of the sheet panel. Features. The second of the mounting structure
Embodiment, the through hole of the seat panel is greater diameter of the surface side, transmembrane with a diameter smaller tapered inner surface of the back side
Except Ru passing Anadea is the same as the first embodiment.

According to a third aspect of the structure of the present invention, a plurality of the sheet panels are mounted on the surface of the structure in an aligned state, and the through holes and joints are formed on the surface of the first-layer sheet panel. It is characterized in that the second-layer sheet panel to be covered is joined by an adhesive. In that case,
Further, a third-layer sheet panel covering those joints may be joined to the surface of the second-layer sheet panel by an adhesive.

As the seat panel used in the above-described method and structure, a seat panel made of a synthetic resin, in which a plurality of stepped through holes are formed so as to be substantially uniformly arranged with respect to the spread of the seat panel, is provided. Is preferred. Furthermore, a first sheet made of a synthetic resin having a small-diameter through-hole and a second sheet made of a synthetic resin provided with a large-diameter through-hole concentric with the small-diameter through-hole are bonded thereon. Things can also be adopted. The second sheet may be an elastic foam sheet made of a synthetic resin foam.

[0012]

In the method of the present invention, when applied to a structure, the adhesive adheres to the structure by its adhesive force. And when you press the sheet panel on it, it also adheres with adhesive force
Then, the adhesive enters the through hole. Then the through hole
The overflowing adhesive is flush with the surface of the sheet panel.
Make sure that the adhesive is on the surface of the sheet panel.
Do not protrude . When the adhesive cures, but are securely bonded to the structure and the adhesive, no bonding between the adhesive and the sheet panel. However, since the adhesive that has entered the through-hole hardens, the sheet panel is mechanically engaged, so to speak. That is, since the through hole is larger on the front surface side than on the back surface side, the adhesive that has entered the through hole and hardened engages with the inner surface of the through hole to act as an anchor. So the adhesive is the sheet
Irrespective of not protruding to the surface side of the panel , the sheet panel does not fall off the surface of the structure, and is kept pressed tightly against the adhesive on the surface of the structure.

If the through hole is not filled with the adhesive when the sheet panel is pressed against the surface of the adhesive, the remaining cavity is additionally filled with the adhesive from the outside. The sheet panel is more securely held because the agent and the agent are integrated and cured. In addition, if the sheet panel is pressed while the adhesive is cured, there is no possibility that a gap is formed between the adhesive and the sheet panel during the pressing.

According to the second method of the present invention, the second or third layer sheet panel is directly bonded to the lower layer sheet panel by an adhesive. Therefore, the mechanical bonding of the first-layer sheet panel and the bonding of the second- and third-layer sheet panels with an adhesive make the whole unitary and the adhesive in the through-hole of the first layer and the lower Any adhesive exposed at the joints of the layers is covered by the sheet panel of the second or higher layer. Therefore, chemical resistance, weather resistance, water resistance, and the like are further increased.

FIG. 6 is a front view of the structure of FIG. 5, FIG. 7 is an enlarged view of a main part of FIG. 6, FIG. 8 is a process diagram showing another embodiment of the method of the present invention,
8 is an enlarged view of a main part of FIG. 7, FIGS. 9 to 11 are cross-sectional views of a main part showing another embodiment of the seat panel according to the present invention, and FIG. 11 shows still another embodiment of the method of the present invention. It is a partial process drawing.

In FIG. 1, reference numeral 1 denotes a concrete wall to which a seat panel is to be attached, and reference numeral 2 denotes a synthetic resin seat panel. A layer of the adhesive 3 is interposed between the two. The wall 1 is provided with a sheet panel 2 for blocking the outside air or providing waterproofness, for example, an inner wall of a tunnel, a concrete retaining wall, a seawall, an outer wall of a building, an inner wall of a basement or an underground garage, or an inner wall of an aquarium. It is an object to be protected. The material of the wall may be concrete, mortar, ceramic material, metal, wood, or the like.

The sheet panel 2 is made of a plastic such as polyvinyl chloride or polypropylene which has no adhesive effect with a commonly used epoxy resin, urethane resin or synthetic resin adhesive such as polypropylene.
These sheets are cut into, for example, a square having a side length of about 30 to 60 mm or molded into the shape (see FIG. 2). This size is preferable because it is easy to handle, but may be larger or smaller. The thickness of the seat panel 2 is usually about 1.2 to 6 mm, preferably
It is about 3.2 mm. As shown in FIG. 2, the seat panel 2 is provided with through holes 4 at equal intervals in, for example, four rows and four digits.

In this embodiment, the through hole 4 has a diameter d on the back side of the sheet panel 2 (the side stuck to the concrete wall 1).
Is small, the diameter D on the front side is increased, and a step 5 is provided in the middle. The diameter of the through hole 4 varies depending on the thickness of the sheet panel 2.
The thickness is about twice as large as the same thickness. When the thickness of the sheet panel is about 3.2 mm, the interval L between the through holes 4 is usually about 10 mm to about 30 mm. In general, the position of the step 5 is about half the thickness of the sheet panel. The cross-sectional shape of the through hole 4 is a normal circle, but may be other shapes such as a square and an ellipse.

As the adhesive 3, the above-mentioned epoxy resin, urethane resin, or synthetic resin adhesive such as polypropylene is used. These adhesives have an adhesive effect on concrete and harden after bonding. In addition, what maintains elasticity after hardening may be sufficient. The adhesive 3 has such a viscosity that the adhesive 3 can be applied to a vertical wall or a ceiling surface, and that the adhesive 3 penetrates into the through hole 4 when the sheet panel 2 is pressed against the wall 1 as described later. The penetrated portion 6 a is hardened in the through hole 4. When the through holes 4 are not filled, the remaining cavities are additionally filled with the adhesive 6b. In that case, the portion 6a that has entered the through hole 4 from the back surface side and the additionally filled portion 6b are integrated. The thickness of the layer of the adhesive 3 varies depending on the surface roughness of the concrete upper wall, the degree of finishing, or the degree of pressing force of the sheet panel 2,
Usually, it is preferably 0.1 to 0.3 mm, particularly preferably about 0.2 mm.

The seat panel mounting structure shown in FIGS. 1 and 2 is constructed by, for example, a method shown in FIGS. That is, first, dirt and latency (free lime) on the surface of the concrete wall 1 are removed by sander or blast. Next, a putty-like adhesive 3 is applied to the surface of the wall 1 (see FIG. 3A). Further, before the adhesive 3 is cured, the sheet panel 2 is pressed against the surface of the sheet panel 2 in such a direction that the small diameter side of the through hole 4 becomes the adhesive side (FIG. 3B).
At this time, a part 6 of the adhesive 3 is pressed with a force enough to be pushed into the through hole 4 (FIG. 3C). Seat panel 2
When a plurality of sheets can be attached, the adjacent sheet panels 2 are arranged so as to be in contact with each other as shown in FIG.

When the adhesive 6 entering the through hole 4 fills the through hole 4, the adhesive is cured as it is. However, since the adhesive has a large viscosity, the portion where the diameter of the through hole 4 is large is not filled. Therefore, the remaining cavity (K in FIG. 3C) is additionally filled with the adhesive 6b, and finished to be flush with the surface of the sheet panel 2 (FIG. 3D). When the adhesive 3 applied to the wall 1 fills the through hole 4 by simply pressing the sheet panel 2 and further overflows, the overflowed adhesive is finished to be flush with the surface of the sheet panel. Thereafter, the adhesives 3, 6a, 6b are cured, and the mounting structure shown in FIGS. 2 and 4 is completed.

In the above-described sheet panel mounting method, even when the adhesive and the sheet panel have almost no adhesive strength, the adhesive before curing has an adhesive strength enough to support the weight of the sheet panel. , The seat panel does not fall off. When the adhesive 3 cures, the weight is supported by the portion 6a that has entered the through hole 4, and the additionally filled large diameter portion 6b is engaged with the inner surface of the through hole 4, so that it is in close contact with the wall 1 side. Is reliably maintained. That is, after the adhesives 6a and 6b in the through holes 4 are hardened, the sheet panels 2 are hardened by a so-called mechanical fastening force or holding force.
Will be held.

In the above method, the joint 7 of each sheet panel 2 is
Adhesive also penetrates. Therefore, if the adhesive has water resistance, the surface of the concrete wall 1 is surely covered with the sheet panel 2 and the water resistant layer. This can be applied, for example, when lining an inner wall of a concrete water storage tank, basement or the like for waterproofing.

On the other hand, when the sheet panel 2 is to be mounted on the inner surface of the tank containing the chemical, the opening of the through hole 4 and the joint 7 are required.
The adhesive exposed from the surface may be attacked by chemicals. In addition, in the case of a seawall or the like, the exposed adhesive may not have sufficient water resistance or weather resistance. In those cases, as shown in FIGS. 5 and 6, the second-layer sheet panel covers the surface 11 of the adhesive 6 b exposed from the through hole 4 and covers the joint 7. Preferably, 13 is provided. The second-layer sheet panel 13 is preferably bonded by the second adhesive 14 after the adhesive 3 of the first (first-layer) sheet panel 2 is sufficiently cured. Such a second adhesive 14 may be any as long as it can bond the first-layer sheet panel 2 and the second-layer sheet panel 13, and the adhesive force with the wall 1 such as concrete is not necessary. Absent. The second adhesive 14 may be applied to the front surface of the first-layer sheet panel 2 or may be applied to the back surface of the second-layer sheet panel 13.

The second adhesive 14 adheres the second-layer sheet panel 13 to the first-layer sheet panel 2 over the entire adhesive surface, and after being cured like the original adhesive 3 The engagement does not exert a mechanical holding force. Therefore, there is no need to provide a thick layer, and it is hardly exposed to the outside. For this purpose, it is not necessary to make the chemical resistance, weather resistance or water resistance particularly high. However, higher ones may be used in some cases. As the sheet panel 13 of the second layer, the same as the sheet panel 2 of the first layer, that is, a sheet of polyvinyl chloride, polypropylene, or the like can be adopted. Further, a panel made of metal, ceramic, wood, or the like can be used. However, since the through hole 4 for obtaining a mechanical holding force as in the first layer is unnecessary, the thickness may be as thin as about 0.6 mm or more.

FIG. 7 shows the first and second layers of the sheet panel 2,
The intersection 16 of the 13 joints 7 and 15 is shown in an enlarged manner. In this portion, the adhesives 3 and 14 are exposed. It is preferable that the joints 16 of the joints be sealed from the outside air by heating the sheet panels 2 and 13 or melting and fusing other thermoplastic resins. Such sealing further improves the water resistance and chemical resistance of the entire seat panel mounting structure.

FIG. 8 shows a state in which the third-layer sheet panel 17 is further adhered and attached so as to hide the joint 15 of the second sheet panel 13 shown in FIGS. By covering with such a third-layer sheet panel 17, water resistance, weather resistance, and chemical resistance can be further improved. The third layer sheet panel 17 may be the same as the second layer sheet panel 13, and the adhesive for the third layer sheet panel 17 may be the same as the second layer sheet panel adhesive. Even when the third-layer sheet panel 17 is bonded as described above, it is preferable to fuse the intersections between the joints as in the case of FIG.

The sheet panel of the embodiment (the first layer sheet panel in the case of a multi-layer) is formed by additionally processing a through hole 4 in one sheet made of synthetic resin like the first sheet panel 2. Alternatively, they can be manufactured by forming them simultaneously with molding the sheet panel. However, as shown in FIG. 9, through holes 4a having different diameters,
The sheet panel 18 in which the two sheets 2a and 2b on which the sheets 4b are formed may be integrated by heat welding without adhesion. In this case, the processing of the through holes 4a and 4b is simple, and it can be manufactured relatively easily. The through hole of the sheet panel in the present invention may be not only a stepped through hole having a different diameter but also a through hole 19 having a tapered inner surface as shown in FIG. Even in such a through-hole 19, by using the side having a small diameter as the mounting surface, the adhesive filled therein acts as a so-called anchor, and the same mechanical effect as in the above-described embodiment is obtained. The holding power can be obtained.

The sheet panel 20 shown in FIG. 11 is a laminated sheet panel comprising an elastic sheet 21 made of a synthetic resin foam and an ordinary solid sheet 22. The solid sheet 22 may be made of the same material as the sheet panel shown in FIG. As the elastic sheet 21, a foam of the same material as described above (expansion ratio of about 10 to 60), a synthetic resin foam such as urethane resin, or a foam of rubber can be employed. This can be used, for example, for repairing a cracked concrete surface under an environment where temperature changes are severe. That is, dirt and latence on the concrete surface are removed with a sander or blast, an adhesive 23 having a rubber elasticity such as urethane is applied, and the laminated sheet panel 20 is pressed and adhered and fixed. Then, the same type of adhesive is added to the through hole from the front surface side to finish the surface evenly, and the adhesive 23 is completed by curing.

That is, in an environment in which the temperature changes drastically, the difference between the linear expansion of the sheet panel and the linear expansion becomes large. However, according to the construction method of this embodiment, the thermal deformation of the solid sheet panel 22 exposed to the surface is increased. Can be absorbed by the elastic deformation of the lower elastic sheet 21 and the rubber elastic adhesive 23. In addition, even if the adhesive 23 maintains rubber elasticity after curing, it can sufficiently support the weight of the sheet panel 20 and can be securely engaged by an anchoring action of a portion having a large outer diameter. Elastic foam sheet 2
1 has high heat insulation properties, and can be used as interior and exterior materials for residential buildings. In addition, the above-described embodiment (FIGS.
6 to 6 and FIG. 7), it is preferable to use the laminated sheet panel 20 in an environment where the temperature changes drastically. In addition, since the end face portion of the foamed elastic sheet 21 is exposed to the outside, the multi-layer sheet panel arranged at the peripheral portion or the corner portion is bent to the outer layer solid sheet panel 22 and subjected to welding processing or the like to match the current shape. It can be processed and attached.

In any of the above embodiments, FIG. 12 shows the case where the sheet panel is heavy and is difficult to adhere and fix only by the viscosity of the adhesive, for example, when it is attached to a vertical wall surface or a ceiling surface, particularly a wet surface. A concrete anchor 30 for temporary fixing may be used. There is no need to provide a large number of such concrete anchors 30 as in the conventional method, and it is sufficient to provide, for example, about one or two places on one sheet panel. The concrete anchor 30 and the anchor bolt 31 used for it are preferably made of plastic. In FIG. 12, reference numeral 32 denotes a plastic washer, and reference numeral 33 denotes a nut. The adhesive 6b outside the step of the through hole 4 is filled from the outside. The protrusion of the anchor bolt 31 is cut off after the adhesive has hardened. This temporarily fixes the sheet panel 2 by the tightening force of the nut 33 while the adhesive 3 is hardening,
It prevents the adhesive from shifting or peeling during curing. After the curing, the mechanical anchoring action of the adhesive in the other through-holes further applies the mechanical holding force of the outer adhesive 6b and the anchor bolt 31, thereby securely holding the sheet panel 2. In addition, a sheet panel of the second layer or the third layer as shown in FIGS.

In any of the above embodiments, it is preferable that a release paper is previously attached to the surface of the sheet panel. As a result, it is possible to prevent contamination due to adhesion of an adhesive during operation.

[0035]

According to the method of the present invention, a sheet panel made of a synthetic resin or the like, which does not have an adhesive action with a normal adhesive, is securely attached to a concrete wall or the like by the mechanical engagement action of the adhesive. be able to. Moreover, it is only necessary to perform a simple perforating process on the seat panel, and there is no need to provide projections such as anchors (legs).
