Description

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 structure. More specifically, the present invention relates to a method of attaching a plastic sheet panel that cannot be bonded with an adhesive such as epoxy resin / urethane resin or acrylic resin to the surface of concrete, ceramic, metal, wood, or the like. These seat panels are made of materials that are resistant to outside air, waterproof, chemicals, etc.
It is used as an anticorrosive material, especially for lining water tanks made of concrete or metal, for waterproofing linings in basements and underground garages, for protecting the inner surfaces of tunnels and revetments, and for protecting the outer walls of various structures.

2. Description of the Related Art Since a sheet panel made of plastic such as polyvinyl chloride, polypropylene or polyethylene is not effective with the above adhesive, it is mechanically attached to a concrete surface. For example, when a sheet panel is attached to a concrete surface in advance, as shown in FIG. 13, an anchor projection 51 is integrally molded on the concrete surface side of the sheet panel 50, and this is fixed to a form 52 with a screw 53 and a nut. A construction method is employed in which 54 is used or nails or double-sided adhesive tape is used for attachment, concrete 55 is then placed, and the mold is removed after the concrete hardens. Note that FIG.
In FIG. 5, 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.

Further, when retrofitting to 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 as a gap filler is provided on the surface of the concrete 55. The sheet panel 63 having the holes 62 is applied, and the sheet panel 63 having the holes 62 is disposed thereon, and the anchor bolt 64 is screwed into the concrete anchor 60 to attach the sheet panel 65. As shown in FIG. 15, the seat panel 6
The key-like projections 66 are integrally provided on the plate 5, and a washer 67 is fitted to the projections 66 at predetermined positions on the concrete surface.
(See FIG. 16) is attached using the concrete anchor 60 and the anchor bolt 64, and the seat panel 65 is attached.
The protrusion 66 is pushed into the washer 67 to be fitted therein, and the cement slurry 68 or the like is injected and filled into the gap between the sheet panel 65 and the concrete 55 to be fixed.

In the above-mentioned pre-attachment method (FIG. 13), it is necessary to provide projections 51 for concrete anchors on the sheet panel, and since it is pre-attached, it cannot be used for the purpose of repairing an existing concrete wall, etc. Limited On the other hand, the conventional method of providing an existing concrete wall (FIGS. 14 and 15) requires a large amount of concrete anchors and the like, which makes the construction difficult. In particular, the method of using the washer 67 requires a difficult forming process of providing a key-shaped projection on the seat panel, and moreover a special washer or the like must be used frequently. In addition, it is necessary to inject and fill the gap with cement slurry or the like. Therefore, material cost and working cost are required, which is not economical.

On the other hand, when the purpose of mounting the seat panel is to shield it from the outside air or to waterproof it, and the seat panel is used as a material for thickening the coating material, the filler is covered with the seat panel. There is no problem in terms of functionality even with the conventional method (however, it is not economical in terms of cost). However, when it is desired to function as an anti-corrosion material or an anti-corrosion material against chemicals, the interstitial material such as cement slurry is exposed on the surface at the joints of the seat panel, so the corrosion resistance is insufficient. . That is, with the passage of time, the joints are corroded by water and chemicals, and eventually the concrete inside is also corroded.

[0006]

The present invention basically does not require the use of concrete anchors and can employ a flat sheet panel without protrusions, and can be easily attached to a concrete wall or the like by retrofitting. It is a technical issue to provide a seat panel mounting method and mounting structure that can be used, which makes it rational for the purpose of use, simplifies the complicated steps of the conventional method, and is economical in terms of cost. The purpose is to contribute to the maintenance and preservation of social capital.

[0007]

A method of mounting a seat panel according to the present invention is a method of applying a curing agent to a mounting surface of a structure or the like by applying an adhesive having an adhesive action to the surface and hardening after bonding. It is characterized in that a sheet panel having a through hole whose front surface side is larger than the back surface side is pressed against the front surface of the adhesive before it is introduced into the through hole, and then the adhesive is cured. In such a method, it is preferable that the sheet panel is pressed against the surface of the adhesive to introduce the adhesive into the through hole, and then the remaining cavity of the through hole is filled with additional adhesive from the surface side.

According to a second method of the present invention, after a plurality of sheet panels are aligned and attached to the attachment surface by the above-described method, the sheet panels are further attached to the surfaces of the sheet panels through holes and through holes. 2 at the position that covers the joint
It is characterized in that the sheet panels of the second layer are overlapped with each other and the two sheet panels are adhered to each other with an adhesive having an adhesive action. Note that the joints here are not limited to those formed with a gap in particular, and also mean joints between sheet panels that are closely adjacent to each other. After mounting the second-layer sheet panel, the third-layer sheet panel is superposed on the surface of the second-layer sheet panel so as to cover the joints of the second-layer sheet panel, and an adhesive action is exerted between both sheet panels. You may make it adhere | attach with an agent. In those cases,
The intersection of the joints of the lower layer and the upper layer is preferably sealed by welding.

The seat panel mounting structure of the present invention comprises a structure, a seat panel mounted on the surface of the structure, and an adhesive interposed therebetween, and the seat panel has a front surface side larger than a back surface side. In addition to having a through hole, the adhesive is filled in the through hole and integrally cured with the adhesive on the back surface side of the sheet panel. The through-hole of the seat panel may be a stepped hole having a large diameter on the front surface side and a small diameter on the rear surface side, or a tapered inner surface having a large diameter on the front surface side and a small diameter on the rear surface side. It may have holes.

In a second structure of the present invention, a plurality of the sheet panels are attached to the surface of the structure in an aligned state, and the surface of the first-layer sheet panel covers the through holes and joints. It is characterized in that the sheet panels of the layers are joined by an adhesive. In that case, the third-layer sheet panel covering the joints may be further joined to the surface of the second-layer sheet panel with an adhesive.

The seat panel used in the above method and structure is a seat panel made of synthetic resin in which a plurality of stepped through holes are formed to be arranged substantially evenly with respect to the spread of the seat panel. Is preferred. It further comprises a synthetic resin first sheet having a small-diameter through hole, and a synthetic resin second sheet having a large-diameter through hole concentric with the small-diameter through hole, which is joined thereto. It is also possible to adopt one. The second sheet may be an elastic foam sheet made of synthetic resin foam.

[0012]

In the method of the present invention, the adhesive, when applied to the structure, adheres to the structure due to its adhesive force. Then, when the sheet panel is pressed on it, it adheres with the same adhesive force. When the adhesive hardens, the structure and the adhesive are surely joined, but the adhesive and the sheet plate are not joined. However, the sheet plate is mechanically engaged, so to speak, because the adhesive that has entered the through-hole is cured. That is, since the through-hole is larger on the front surface side than on the rear surface side, the adhesive that has entered and cured in the through-hole engages with the inner surface of the through-hole and acts as an anchor. Therefore, the sheet panel does not fall off the surface of the structure, and the state in which the sheet panel is closely pressed against the adhesive on the surface of the structure is maintained.

When the through hole is not filled with the adhesive when the sheet plate is pressed against the surface of the adhesive, the remaining cavity is additionally filled with the adhesive from the outside, and the added adhesive and the original adhesive are bonded. The sheet panel is held more securely because the agent and the agent are integrated and cured. Further, if the sheet panel is pressed while the adhesive is being cured, there is no possibility that a gap will be created between the adhesive and the sheet panel during the process.

According to the second method of the present invention, the sheet panel of the second layer or the third layer is directly bonded to the sheet panel of the layer below it by an adhesive. Therefore, the mechanical bonding of the first-layer sheet panel and the bonding of the second-third-layer sheet panel with the adhesive integrate the whole, and the adhesive in the through-hole of the first layer and Any adhesive exposed at the joints of the layers is covered by the sheet panel of the second or upper layer. Therefore, chemical resistance, weather resistance, water resistance, etc. are further enhanced. Further, in the case of sealing the intersection of joints by welding, the surface of the adhesive is almost completely covered with the sheet panel, so that the chemical resistance is further improved.

In the seat panel mounting structure of the present invention, the adhesive and the structure are joined by an adhesive action, and the adhesive and the sheet plate are mechanically so-called mechanically connected to each other by the adhesive entering the through hole. Have been combined. That is, since the through-hole is larger on the front surface side than on the rear surface side, the sheet panel does not fall off the surface of the structure, and the state in which the sheet panel is closely pressed against the adhesive on the surface of the structure is maintained. In the second structure of the present invention, since the adhesive appearing on the surface of the first-layer sheet panel is covered by the second- or third-layer sheet panel, chemical resistance, weather resistance, and
High water resistance. The upper and lower sheet panels in which the joints where the joints intersect are joined by welding have higher chemical resistance and the like.

When the through holes of the sheet panel are provided at substantially equal intervals, it is preferable because the adhesion to the bonding ground becomes even. A laminated sheet panel composed of a foam first sheet and a solid second sheet on top of it absorbs the difference in linear expansion coefficient between the structure and the sheet panel even when used in an environment where the temperature changes drastically. Therefore, the seat panel is not subjected to excessive force.

FIG. 6 is a sectional view showing another embodiment of the present invention, 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, and FIG. 8 is a process drawing 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 is a concrete wall to which a seat panel is to be attached, and 2 is a synthetic resin seat panel. A layer of adhesive 3 is interposed between the two. The wall body 1 is, for example, an inner wall of a tunnel, a concrete retaining wall, a revetment wall, an outer wall of a building, an inner wall of a basement / underground garage, an inner wall of an aquarium, etc. It is an object to be protected. The material of the wall body may be mortar, ceramic material, metal, wood, etc. other than concrete.

The seat panel 2 is made of plastic such as polyvinyl chloride or polypropylene, which has no adhesive effect with a commonly used epoxy resin type, urethane resin type, or synthetic resin type adhesive such as polypropylene.
These sheets are, for example, cut into a rectangular shape having a side length of about 30 to 60 mm or molded into that shape (see FIG. 2). This size is preferable because it is easy to handle, but it may be larger or smaller than this. 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, for example, in four rows and four digits.

In this embodiment, the through hole 4 has a diameter d on the back side of the seat panel 2 (the side to be attached to the concrete wall 1).
Is small, the diameter D on the front surface side is large, and a step 5 is provided in the middle. Although the diameter of the through hole 4 varies depending on the thickness of the seat panel 2, for example, the seat panel 2
The thickness is about the same as about 2 times. The distance L between the through holes 4 is usually about 10 mm to about 30 mm when the thickness of the seat panel is about 3.2 mm. The position of the step portion 5 is generally about half the thickness of the seat panel. The cross-sectional shape of the through hole 4 is a normal circle, but it may be another shape such as a square or an ellipse.

As the adhesive 3, the above-mentioned epoxy resin adhesive, urethane resin adhesive, or synthetic resin adhesive such as polypropylene is used. These adhesives have an adhesive effect on concrete and are hardened after the adhesion. It may be one that maintains elasticity after curing. The adhesive 3 has such a viscosity that it can be applied to a vertical wall or a ceiling surface, and that it will penetrate into the through hole 4 when the sheet panel 2 is pressed against the wall 1 side as described later. The penetrated portion 6a is hardened in the through hole 4. When the through hole 4 is not filled, the remaining cavity is 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 0.1 to 0.3 mm, preferably about 0.2 mm.

The seat panel mounting structure shown in FIGS. 1 and 2 is constructed, for example, by the method shown in FIGS. That is, first, dirt and leitance (free lime) on the surface of the concrete wall body 1 are removed by a sander or a blast. Then, a putty-like adhesive 3 is applied to the surface of the wall body 1 (see FIG. 3a). Further, before the adhesive 3 is cured, the sheet panel 2 is pressed against the surface of the sheet 3 in such a direction that the small diameter side of the through hole 4 is the adhesive side (FIG. 3b).
At this time, a part 6 of the adhesive 3 is pressed into the through hole 4 with a force enough to be pushed out (FIG. 3c). Seat panel 2
When a plurality of sheets are 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, it is cured as it is. However, since the viscosity of the adhesive is usually large, 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 to finish flush with the surface of the sheet panel 2 (FIG. 3d). In addition, when the adhesive 3 applied to the wall 1 fills the through holes 4 only by pressing the sheet panel 2 and further overflows, the overflowing adhesive is finished flush with the surface of the sheet panel. After that, the adhesives 3, 6a, 6b are hardened, and the mounting structure as shown in FIGS. 2 and 4 is completed.

In the above seat panel mounting method, since the adhesive before curing has sufficient adhesive strength to support the weight of the seat panel even when there is almost no adhesive strength between the adhesive and the seat panel. , The seat panel does not fall off. Then, when the adhesive 3 is cured, the weight is supported by the portion 6a that has entered the through hole 4, and the additionally filled portion 6b having a larger diameter engages 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, they are mechanically tightened or held by a so-called mechanical fastening force or holding force.
Will hold.

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

On the other hand, when the sheet panel 2 is mounted on the inner surface of the tank containing the chemicals, the opening of the through hole 4 and the joint 7 are formed.
The exposed adhesive may be chemically attacked. In addition, the water resistance or weather resistance of the exposed adhesive may not be sufficient on the seawall. In those cases, as shown in FIGS. 5 and 6, the second-layer sheet panel so as to cover the surface 11 of the adhesive 6b exposed from the through hole 4 and to cover the joint 7 portion. It is preferable to provide 13. The second layer sheet panel 13 is preferably adhered with the second adhesive 14 after the adhesive 3 of the first (first layer) sheet panel 2 is sufficiently cured. The second adhesive 14 may be one that can bond the first-layer sheet panel 2 and the second-layer sheet panel 13, and the adhesive strength to the wall body 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 the back surface of the second-layer sheet panel 13.

The second adhesive 14 is for adhering the second-layer sheet panel 13 to the first-layer sheet panel 2 over the entire bonding surface, and after being hardened like the original adhesive 3, No mechanical holding force is exerted by the engagement. Therefore, it is not necessary to provide it thickly, and it is hardly exposed to the outside. Therefore, chemical resistance, weather resistance or water resistance does not need to be particularly high. However, higher one may be used depending on the case. The second layer sheet panel 13 may be the same as the first layer sheet panel 2, that is, a sheet of polyvinyl chloride, polypropylene or the like. Further, a panel made of metal, ceramic, wood or the like can be used. However, unlike the first layer, the through hole 4 for obtaining a mechanical holding force is not necessary, so the thickness may be as thin as about 0.6 mm or more.

FIG. 7 shows a sheet panel 2 of a first layer and a second layer,
The intersection 16 of the 13 joints 7 and 15 is shown in an enlarged manner. The adhesive 3, 14 is exposed at this portion. It is preferable that such a joint 16 of the joint is sealed from the outside air by heating the sheet panels 2 and 13 or by melting and melting another thermoplastic resin. By sealing in this manner, the water resistance and chemical resistance of the entire seat panel mounting structure are further improved.

FIG. 8 shows a state in which a third layer sheet panel 17 is further attached and attached so as to hide the joints 15 of the second sheet panel 13 of FIGS. 5 and 6. 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 adhesive for the second layer sheet panel. Even when the third-layer sheet panel 17 is bonded in this way, it is preferable to fuse the intersections of the joints, as in the case of FIG. 7.

The sheet panel of the above-mentioned embodiment (the sheet panel of the first layer in the case of multiple layers) is obtained by additionally processing the through holes 4 in one synthetic resin sheet like the first sheet panel 2. Alternatively, they can be manufactured by forming them simultaneously when 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 sheet 4b is formed may be integrated by heat welding without adhesion. The through-holes 4a and 4b are easy to process, and can be manufactured relatively easily. The through holes of the seat panel according to the present invention may be not only stepped through holes having different diameters but also through holes 19 having a tapered inner surface as shown in FIG. Even in such a through hole 19, the adhesive filled in the inside of the through hole 19 acts as a so-called anchor by using the side having a smaller diameter as a mounting surface, and the same mechanical effect as in the case of the above-described embodiment is obtained. Holding power can be obtained.

The sheet panel 20 shown in FIG. 11 is a laminated sheet panel including an elastic sheet 21 made of 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 foamed material (foaming ratio of about 10 to 60) made of the same material as described above, a synthetic resin foamed material such as urethane resin, or a rubber foamed material can be adopted. This can be used, for example, for repairing a concrete surface where cracks have occurred in an environment where the temperature changes drastically. That is, dirt and leitance on the concrete surface are removed by a sander or blast, an adhesive 23 having rubber elasticity such as urethane is applied, and the laminated sheet panel 20 is pressed and attached / fixed. Then, an adhesive of the same type is added to the through hole from the front surface side to finish the surface flush and the adhesive 23 is cured to complete the process.

That is, in an environment where the temperature changes drastically, the difference in linear expansion between the sheet panel and the concrete becomes large, but according to the construction method of this embodiment, the thermal deformation of the solid sheet panel 22 exposed to the surface. Can be absorbed by elastic deformation of the lower elastic sheet 21 and the rubber elastic adhesive 23. Even with the adhesive 23 that maintains rubber elasticity after curing, the weight of the sheet panel 20 can be sufficiently supported, and the seat panel 20 can be reliably engaged by the anchor action of the portion having a large outer diameter. Elastic foam sheet 2
Since No. 1 has a high heat insulating property, it can be used as an interior / exterior material of a residential building. In addition, the above-described embodiment (FIGS. 3 to 4 and FIG.
6 to 7), it is preferable to use this laminated sheet panel 20 in an environment where the temperature changes drastically. In the multi-layered sheet panel arranged in the peripheral portion or the corner portion, the end surface portion of the foamed elastic sheet 21 is exposed to the outside, so that the solid sheet panel 22 of the outer layer is bent and welded to match the current shape. It can be processed and attached.

In any of the above-mentioned embodiments, when the sheet panel is heavy and it is difficult to attach and fix it only by the viscosity of the adhesive, for example, when it is attached to a vertical wall surface or ceiling surface, particularly a wet surface, it is shown in FIG. A concrete anchor 30 for temporary fastening may be used. It is not necessary to provide a large number of such concrete anchors 30 as in the conventional method, and one sheet panel may have, for example, one or two places. The concrete anchor 30 and the anchor bolt 31 used therefor are preferably made of plastic. In FIG. 12, reference numeral 32 is a plastic washer and reference numeral 33 is a nut. The adhesive 6b outside the step of the through hole 4 is filled from the outside. The protruding portion of the anchor bolt 31 is cut off after the adhesive is hardened. In this product, while the adhesive 3 is being cured, the seat panel 2 is temporarily fixed by the tightening force of the nut 33,
Prevents the adhesive from shifting or peeling during curing. After hardening, the mechanical anchoring action of the adhesive in the other through-holes further applies the mechanical holding force of the adhesive 6b on the outside and the anchor bolt 31 to securely hold the seat panel 2. It should be noted that this may be provided with a second to third layer sheet panel as shown in FIGS.

In any of the above-mentioned embodiments, it is preferable to previously attach release paper to the surface of the sheet panel. As a result, it is possible to prevent stains due to adhesion of adhesive during work.

[0035]

According to the method of the present invention, a sheet panel made of synthetic resin or the like, which does not have an adhesive action with an ordinary adhesive, is securely attached to a concrete wall or the like by the mechanical engaging action of the adhesive. be able to. Moreover, the seat panel need only be subjected to a simple perforating process, and it is not necessary to provide protrusions such as anchors (legs).
