Description

  The present invention relates to a structure for attaching a plate member to a tunnel wall surface to which a plate member such as a tile is attached to a wall surface of the tunnel via support means.

  The mounting structure of a plate member such as a tile to a tunnel wall surface includes a mounting structure in which a plate member such as a single tile is directly attached to the wall surface via an adhesive such as mortar, and a plate member such as a plurality of tiles is mortared. There is an attachment structure in which a panel constituted by bonding and bonding to the surface of a substrate such as the like is attached to a wall surface via support means such as an attachment fitting.

  The former is a method in which a plate member such as a single tile is directly attached to a wall surface via an adhesive such as mortar, and the efficiency is not good, but there is a possibility that they will be peeled off due to deterioration of the adhesive. Stripping tiles in the tunnel may cause a major accident and should be avoided as much as possible. In that sense, it is a mounting structure that is difficult to adopt at present.

Regarding the latter, the panel mounting method of Patent Document 1 has been proposed.
In this construction method, a panel in which a plurality of tiles are bonded to a substrate made of an iron plate, fiber cement plate, or the like with an adhesive is attached to the inner wall surface of the tunnel via an attachment fitting. The mounting brackets are arranged at the four corners of the panel. The panel has notches in the four corners between the substrate and the tile. An anchor made up of a screw and a sleeve is arranged on the mounting bracket, and this is fixed to the tunnel wall surface. In addition, a metal piece fixed to the anchor is attached to the mounting bracket, and the metal piece includes a claw piece referred to as two upwardly facing strips, and two downwardly facing strips located on both sides thereof. The claw piece to call is comprised. One of the two upwardly facing strips is inserted into a notch groove between the substrate and the tile located at the bottom of the panel, and the other upwardly facing strip is in contact with the back to hold the substrate. It becomes a state. Each one of the two pairs of downward strips is inserted into a notch groove between the substrate and the tile located at the top of the panel, and at this time, the other downward strip is It will be in the state which touches back so that this board | substrate may be held.

  The mounting structure of the panel mounted by the panel mounting method of Patent Document 1 is as described above, and since a large number of tiles can be mounted at one time, the work efficiency is very good. Since it is bonded to a substrate such as a plate with an adhesive, there is a risk of peeling due to deterioration of the adhesive. Since the environment inside the tunnel is inferior, the adhesive may deteriorate in a relatively short period of time, and the deterioration of the adhesive causes the tile to fall off, and as mentioned above, the fall of the tile is a major accident. There is a risk of inviting. Therefore, it is considered that a technique using a panel in which tiles are bonded to such a substrate with an adhesive should not be adopted.

  Patent Document 2 relates to a structure for attaching a large tile having a heat-insulating refractory on the back surface to a tunnel wall surface. In this tile, the tile main body and the heat-insulating refractory are joined through a metal fixing means and a metal fixing piece disposed inside the latter. Further, the tile is fixed to the base metal fitting fixed to the inner wall of the tunnel through the metal fixing means and the fixing piece and other intervening metal pieces.

  Therefore, the attachment structure to the tunnel wall surface of the large tile of Patent Document 2 is that the heat insulating refractory is arranged on the back surface of the tile main body as described above, and an adhesive is used for mutual bonding and fixing. Therefore, it can be said that it is an excellent product without fear of peeling off of the tile due to deterioration of the adhesive. In addition, the tile can be securely held on the inner wall surface. However, the attachment structure of the large tile to the tunnel wall surface of Patent Document 2 is an expensive attachment structure provided with a refractory behind the tile body, and is appropriate when such a refractory is not necessarily required. is not.

The anti-floating member which consists of a fixed piece which can be attached to the provided member is attached.

  Therefore, according to the mounting structure of the plate member to the tunnel wall surface according to the first aspect of the present invention, the plate member such as a relatively large tile arranged vertically and horizontally on the wall surface of the tunnel is reliably supported by the supporting means fixed to the wall surface. The Since the plate member is not attached via a plurality of substrate members joined with an adhesive, but directly attached to the wall surface by a supporting means, there is no problem of peeling due to deterioration of the adhesive over time. . Therefore, reliable attachment can be maintained over a long period of time.

  Further, as described above, the supporting means is arranged at the intersection portion of the joints around the plate member arranged on the wall surface, and the lower corners on both sides of the surrounding plate member and the lower parts on both sides are arranged. Since all or a part of the upper corner is supported via one or both of the lower receiving member and the upper receiving member, the efficiency is higher for each plate member than when supporting the lower and upper corners. It is possible to secure support and fixation while being economical (economic). While using a small number of support means, it is possible to avoid the possibility of a rotation state (rotation state in which one side portion is lowered and the other side portion is raised) due to the weight balance or vibration of the plate member.

  There are a plurality of types of intersections at the joint where the support means is arranged, but the most common is a cross-shaped portion located in a region excluding the upper, lower, left and right edges of the region where the plate member is installed. In addition to this, L-shaped parts located at the upper and lower ends of both sides of the region where the plate member is arranged, its upside-down inverted part, these two left-right inverted parts, and the other parts which arrange the plate member A T-shaped portion located at the upper, lower, left and right edges, an inverted portion thereof, a 90-degree rotating portion on the right of the T-shaped portion, and a 90-degree rotating portion on the left of the T-shaped portion. The support means is disposed at a portion corresponding to the intersection in the character portion.

  Among the above-mentioned corresponding joint parts, joint parts located at the upper, lower, left and right edges of the region where the plate member is arranged are different from the inside of the region, and the plate member located at the edge instead of between the plate members. It is a gap located between the external wall surface and other wall surfaces orthogonal to this.

  The supporting means for fixing to the cross-shaped portion in each of the above-mentioned intersection-like portions naturally has plate members located on both the upper side and the lower side of the position, so the lower receiving members are arranged on the corresponding upper sides, The upper receiving members are arranged on the corresponding lower sides to support the lower corners of the upper two plate members and the upper corners of the lower two plate members. The left upper and lower plate members are located at the intersections located at the edges, such as the L-shaped part, the T-shaped part, and their inverted character-like parts in the other intersecting point parts. There are cases where either of the plate members that should be located on both the upper and lower sides of the support means located at the intersection is not located, for example, the plate members on the upper and lower sides are not located. In that case, it goes without saying that the corresponding positions of the lower receiving member and the upper receiving member can be omitted. The same applies to the means for locking them to the support means.

  According to the mounting structure of the plate member to the tunnel wall surface of the present invention, the support means is mounted on the wall surface, the main receiving member attached to the mounting means, and the coupling plate of the main receiving member. Since the lower receiving member and the receiving member locking piece for locking the upper receiving member are arranged, and the horizontal extension plate of the main receiving member is connected to the connecting plate portion of the mounting means so as to be adjusted in a non-landing manner. The main receiving member can be adjusted to be non-landing on the mounting means, and adjusts the non-landing of the receiving member locking piece disposed on the coupling plate, and is supported by the lower receiving member and the upper receiving member. The unevenness of plate members such as tiles can be easily adjusted.

  According to the mounting structure of the plate member to the tunnel wall surface of the present invention 3, it is possible to mount the plate member to be mounted without leaving a wide space between the wall surface, and it is effective in such a case. It is. Since the mounting plate portion of the mounting means is fixed to the wall surface with a plurality of bolts or screws, there is no possibility of rotation, but the connecting plate attached to the front surface is a part of the plurality of bolts or screws. It is attached to the wall surface using one or more attachment plates and the rotation is prevented by rotation stop pieces on both sides of the attachment plate. Therefore, even when the connecting plate is fixed with one bolt or screw, the possibility of rotation is eliminated, and the plate member attached via the upper receiving member and the lower receiving member is stably attached. can do. The unevenness of the plate member can be adjusted by inserting one or more unevenness adjusting plates between the mounting plate part and the connecting plate as necessary.

Since the anti-rotation pieces of the mounting means are located on both sides of the upper stage side locking part and the lower stage side locking part, the rotation of the connecting plate is prevented and at the same time the upper stage side locking part and the lower stage locking part. It is possible to prevent the lower receiving members on both sides and the upper receiving members on both sides that are locked to the side locking portions from coming off to the side. Further, since the elastic inclusion is inserted between the upper part of the upper receiving member locked to the lower side locking part and the upper side locking part of the receiving member locking part, the upper receiving member is lifted. It has become possible to prevent it flexibly.

  According to the mounting structure of the plate member to the tunnel wall surface of 5 of the present invention, since the rotation stop edge bent backward is formed on both sides of the mounting plate portion, the mounting plate portion is joined to the wall surface on the back surface. In this state, when the bolt is fixed to the wall surface using bolts such as anchor bolts or screws such as concrete screws, the support means may cause an imbalance in the weight balance of the plate member due to the action of the rotation stop edge. It is possible to avoid the problem of rotating around the bolts or screws due to the unbalanced load applied.

The latter rotation on the former can be prevented. Moreover, since the elongated hole is opened in the extension plate main body, after placing this on the plate portion main body and adjusting the unevenness, if the bolt member screwed into the female screw portion via the elongated hole is tightened, It is possible to maintain the state after adjusting the unevenness easily.

  According to the mounting structure of the plate member to the tunnel wall surface of 9 of the present invention, each of the upper side locking portion and the lower side locking portion of the receiving member locking portion is composed of a simple plate material, Any of the upper receiving member and the lower receiving member can be secured with a simple configuration. Since the anti-rotation pieces of the mounting means are located on both sides of the upper stage side locking part and the lower stage side locking part, the rotation of the connecting plate is prevented and at the same time the upper stage side locking part and the lower stage locking part. It is possible to prevent the lower receiving members on both sides and the upper receiving members on both sides that are locked to the side locking portions from coming off to the side. In addition, since the upper portion of the upper receiving member locked to the lower side locking portion is restrained by the restraining piece of the anti-lifting member attached to the member fixed to the tunnel wall surface, it is possible to prevent the upper receiving member from rising. It has become.

In the center in the width direction, a screw avoiding slit 171 is formed in the lower portion and extending to the middle of the upper portion. It is appropriate to use a metal having good corrosion resistance, but it is also possible to use plastics. Plastics can also be used because they should be able to play the role of spacers even if they are slightly altered due to adverse effects from the environment. In the second embodiment, a plastic plate material is used.

  As shown in FIGS. 19, 20, and 23 (a) to 23 (c), the receiving metal locking piece 18 is a member having almost the same structure as the receiving metal locking piece 8 of the first embodiment. A connecting plate 181 based on a rectangle which is joined to the mounting plate portion 161 of the mounting bracket 16 and fixed to the wall surface W using the concrete screw 5b on the lower side thereof, and forward from the upper end of the connecting plate 181 The plate-shaped upper side locking portion 182 for locking the lower receiving metal fittings 3, 3 that are overhanged and started upright, and the lower end of the connecting plate 181 that protrudes forward to stand upright.

A screw 5b is inserted and screwed into a prepared hole opened in the wall surface W. The long hole 186 of the connecting plate portion 181 is used in this way.

  The detachment prevention pieces 184 and 184 provided on both sides of the upper side locking portion 182 have the same configuration as the detachment prevention sides 84 and 84 of the first embodiment. Also, the detachment prevention pieces 185 and 185 provided on both sides of the lower side locking portion 183 have the same configuration as the detachment prevention pieces 85 and 85 of the first embodiment.

  In addition, as shown in FIGS. 18 to 20, the receiving bracket locking piece 18 further prevents the upper receiving brackets 4, 4 locked to the lower-stage locking portion 183 from floating. An elastic inclusion 100 to be inserted is provided between the upper portions of the upper receiving brackets 4 and 4 and the upper side locking portion 182 of the receiving bracket locking piece 18. This is exactly the same as in the first embodiment.

  The elastic inclusion 100 is a rod-like member having elasticity. In the second embodiment, as shown in FIGS. 24 (a) and 24 (b), a plurality of protrusions are hard and have a plurality of protrusions along the length direction. Adopted an elastic plastic cylindrical member. Since this member is plastic, the original quality cannot be maintained over a long period of time, but it is arranged in the above-mentioned positional relationship, and if it exists at that position, its function can be generally maintained, so the problem is Absent. In addition, it is as described regarding the first embodiment.

  The upper locking portion 182 of the receiving bracket locking piece 18 locks the two lower receiving brackets 3 and 3 that receive the lower left and right portions of the tiles 1 and 1 positioned above and to the left and right. The lower side locking portion 183 locks the two upper receiving brackets 4 and 4 that receive the upper left and right portions of the tiles 1 and 1 positioned on the lower left and right sides.

  The lower bracket 3 is a symmetrical member, but this is the same as that used in the first embodiment. The usage is naturally the same. The upper receiving bracket 4 is also a symmetrical member, and this is also used as it is in the first embodiment. The usage is naturally the same.

  Therefore, according to the tile mounting structure on the tunnel wall surface of the second embodiment, basically, a large number of large tiles 1, 1... Are securely supported by the support brackets 2b, 2b. The tiles 1, 1... Are not attached via a plurality of substrate members joined with an adhesive, but are directly attached to the wall surface W with the support fittings 2b, 2b. The problem of peeling off due to deterioration does not occur. Therefore, reliable attachment can be maintained over a long period of time. Further, the second embodiment is more effective when a wide space cannot be provided between the wall surface W and the tiles 1, 1.

  The tile mounting structure on the tunnel wall surface of the second embodiment is as described above, and in detail, has the following configuration.

  The tiles 1, 1... Are described in the first embodiment and are arranged vertically and horizontally on the wall surface W of the tunnel as shown in FIG. Also, as shown in FIG. 17 and FIG. 17, each tile 1 supports the vicinity of the corners on both sides of the upper part by the corresponding upper receiving brackets 4 and 4, respectively, and the vicinity of the corners on both sides of the lower part respectively. It is configured to be supported by the lower receiving brackets 3 and 3. Further, as described above, the upper receiving metal fittings 4 and 4 and the lower receiving metal fittings 3 and 3 are supported by the support metal fitting 2b. Further, as described above, the support metal fitting 2b includes a plurality of tiles 1, 1 ... arranged on the wall surface W, or tiles 1, 1 ... located on the outer edge of the installation area of the tiles 1, 1 ... and external members. Are arranged in a portion corresponding to the intersection described above, such as a cross shape, a T-shape, an L-shape, etc. in the joint between the two.

  First, the installation state of the support metal fittings 2b, the lower metal fittings 3 and 3 and the upper metal fittings 4 and 4 arranged at the intersections of the cross-shaped portions in the joint portion and the state of support of the tiles 1 will be described. .

  As shown in FIGS. 18 to 20, the mounting bracket 16 constituting the support bracket 2 b is mounted at the predetermined position on the wall surface W. The arrangement of the tiles 1, 1,... Is determined in advance and attached to the wall surface W behind the cross-shaped portion in the joint portion planned portion. At that position, two pilot holes are opened up and down in advance from the front side, and the mounting plate portion 161 of the mounting bracket 16 is joined thereto, and one concrete is connected from the front side through the long slot 163 for connection. A screw 5b is inserted and screwed into and fixed to the upper one of the pilot holes.

  Thereafter, the connecting plate portion 181 of the catch piece 18 for the metal fitting is joined to the front surface of the mounting plate portion 161 of the mounting bracket 16, and another concrete screw 5b for fixing the mounting plate portion 161 is connected. It inserts into the long hole 186 of the plate part 181 and the coupling long hole 163 of the attachment plate part 161 behind it from the front side, and is screwed and fixed to another pilot hole opened in the wall surface W behind. At this time, it is necessary from the viewpoint of the unevenness adjustment of the tiles 1, 1... Attached via the receiving piece locking pieces 18 and the upper receiving pieces 4 and 4 and the lower receiving pieces 3 and 3 to be fixed thereto. In this case, the necessary number of unevenness adjusting plates 17, 17... Are inserted between the mounting plate portion 161 and the connecting plate portion 181. The unevenness adjusting plate 17 can be easily inserted from above if there is an appropriate gap between the mounting plate portion 161 and the connecting plate portion 181. Since the slits 171 for avoiding screws are formed, the concrete screw 5b does not become an obstacle during and after insertion. After inserting the necessary number of the uneven adjustment plates 17, 17..., The concrete screw 5b is naturally screwed to a necessary position to ensure secure fixing.

  In the above state, the mounting bracket 16 is fixed by the two upper and lower concrete screws 5b and 5b, so that its rotation is reliably prevented. In addition, the receiving metal locking piece 18 fixed to the front surface of the mounting plate portion 161 of the mounting bracket 16 is one in which the connecting plate portion 181 is fixed by a single concrete screw 5b. The movement is blocked by the rotation stoppers 162 and 162 arranged on both sides of the motor. Therefore, in the end, the receiving metal locking piece 18 is also reliably prevented from rotating.

  As described above, the support metal fitting 2b configured at the intersection of the cross-shaped portion in the joint portion has the two tiles 1, 1,. It attaches via the lower receiving metal fittings 3 and 3 and the same two upper receiving metal fittings 4 and 4.

  As described with reference to the first embodiment, the tiles 1, 1,... Are previously attached with upper receiving brackets 4 and 4 in the vicinity of the corners on both sides of the upper portion in the positional relationship shown in FIG. Lower receiving brackets 3 and 3 are attached near the portion. Details are as described in the first embodiment.

  Thereafter, as shown in FIG. 16, the above tile 1 is installed by using the support fittings 2b, 2b,. As shown in FIGS. 18 to 20, the lower receiving metal fittings 3 and 3 on both sides disposed on the tile 1 are engaged with the receiving metal fitting locking pieces 18 of the support metal fittings 2 b and 2 b on both sides immediately below the metal fittings. The upper receiving metal fittings 4, 4 on both sides arranged in the tile 1 are engaged with the receiving metal fitting locking pieces 18 of the supporting metal fittings 2 b, 2 b immediately on the both sides.

The details are as described in the first embodiment and are not different from them.
In each support fitting 2b, as shown in FIGS. 18 to 20, the upper portions of the engagement plates 42 and 42 of the upper receiving brackets 4 and 4 and the lower portion of the upper locking portion 182 of the receiving bracket locking piece 18 The elastic inclusion 100 is inserted in between. In this way, the floating of the upper receiving brackets 4 and 4 and the floating of the tiles 1 and 1 through this are prevented. This is the same as in the first embodiment.

  In the above, even if the tiles 1 and 1 try to move in the lateral direction due to an earthquake or other vibrations, the disengagement prevention pieces 185 disposed on both sides of the lower side locking portion 183 of the receiving metal locking piece 18. , 185 and the upper side locking portion 182 are controlled by the action of the disengagement prevention pieces 184, 184, and the movement is restricted, and the lower side locking portion 183 or the upper side locking portion 182 falls off, respectively. Is prevented. In the second embodiment, since the detachment prevention pieces 184, 184, 185, 185 are formed, it operates as described above. However, even if this is not formed, the locking piece 18 for the receiving metal fitting is operated. If there is little difference in the width of both sides of the connecting plate 181 and the mounting plate portion 161 of the mounting bracket 16 and the distance between both sides of the connecting plate 181 and the rotation stop pieces 162 and 162 of the mounting bracket 16 is small, the rotation The stop pieces 162 and 162 can be prevented from coming off. Therefore, it can be configured as such.

  In the following, a case will be described in which the support metal fittings 2b are arranged at portions other than the intersections of the cross-shaped portions in the joints between the tiles in the installation area of the tiles 1, 1,. Since this is basically the same as that described in the first embodiment, only a brief description will be given.

The case where the support fitting 2b is arranged at the intersection of the T-shaped portion in the joint portion other than the upper corners of the uppermost edge of the tile installation area. In this case, since there are only tiles 1 and 1 on both lower sides of the support metal fitting 2b, the upper metal fittings 4 and 4 are arranged only on both sides of the lower-side engagement portion 183 of the metal fitting engagement piece 18. .
The case where the support fitting 2b is arranged on the opposite L-shaped corners of the uppermost corners of the tile installation area or the left and right symmetrical corners. In this case, since the tile 1 is only on the lower right side or the lower left side of the support metal fitting 2b, the upper metal fitting 4 is arranged only on one side of the lower side latching portion 183 of the metal fitting locking piece 18. .
When the support metal fittings 2b are arranged at the intersections of the lateral T-shaped portions other than the upper and lower corners of the side edge of the tile installation area. In this case, since the tile 1 is only on the right upper and lower sides or the left upper and lower sides of the support metal fitting 2b, the upper metal fitting 4 is provided only on one side of the lower metal side engagement portion 183 of the metal fitting engagement piece 18 and the upper metal fitting 4b. The lower bracket 3 is disposed only on one side of the side locking portion 182.
The case where the support fitting 2b is arranged in the L-shape at the lower corners of the periphery of the tile installation area or the left and right symmetrical corners. In this case, since the tile 1 is only located at the upper right or upper left of the support metal fitting 2b, the lower metal fitting 3 is arranged only on the corresponding side of the upper metal locking portion 182. To do.
The case where the support fitting 2b is arranged at the intersection of the inverted T-shaped portion in the joint portion other than the lower corners of the lower edge of the tile installation area. In this case, since the tiles 1 and 1 are only on the upper both sides, the lower brackets 3 and 3 are disposed only on both sides of the upper-side latching portion 182 of the latching piece 18 for the bracket.

  With regard to the above, since all the configurations other than the above-described points are the same as those arranged at the intersections of the cross-shaped portion, further description is omitted.

  In addition, in the above Example 2, in this Example 2, it comprised using the stainless steel except the tile 1, the elastic inclusion 100, and the unevenness adjustment board 17 which are attachment objects. Although it is possible to employ a metal that has been subjected to sufficient rust prevention treatment, a highly reliable member that can maintain sufficient strength over a long period of time in a poor environment should be employed.

  Therefore, according to the tile mounting structure to the tunnel wall surface of the second embodiment, the relatively large tiles 1, 1... Is surely supported by. Even if the center of gravity of the tile 1 is shifted to the left or right or a strong external force is applied, the support metal fittings 2b, 2b... Are fixed to the wall surface W by the two concrete screws 5b, 5b. There is no problem of going up or left and tilting left or right. That is, it is possible to avoid the possibility that a rotation state (rotation state in which one side portion is lowered and the other side portion is raised) due to vibrations or the like based on the weight balance of the tile 1 itself or an earthquake or the like. Further, as described above, the tiles 1, 1... Are not attached via a plurality of substrate members joined with an adhesive, but are directly attached to the wall surface W with the support fittings 2b, 2b. Therefore, the problem of peeling off due to deterioration of the adhesive during the system does not occur. Therefore, a reliable mounting state can be maintained over a long period of time.

  Further, as described above, the support metal fittings 2b, 2b,... Are arranged at the intersections, etc. in the joints around the tiles 1, 1,. When the tiles 1, 1... Are positioned, the left and right tiles 1 and 1 positioned above and below are supported simultaneously via the lower brackets 3 and 3 and the upper brackets 4 and 4, so that each tile 1, 1. In addition, as compared with the case where the lower corner portions and the upper corner portions are individually supported, it is possible to perform reliable support and fixation while being efficient (economic).

  In addition, among the intersections of the joint portions where the support fittings 2b, 2b,... In those portions, as described above, the number of tiles supported by each of the support brackets 2b, 2b. As described above, only the upper two, only the upper left and right, only the lower left and right, only the lower two, etc.

  Further, according to the second embodiment, the mounting plate portion 161 of the mounting bracket 16 is provided with the necessary number of uneven adjustment plates 17, 17. The plate portion 181 is joined and, as described above, the concrete screws 5b are fixed to the wall surface W at the same time. Since the unevenness of the catching piece 18 for the metal fitting is adjusted, The unevenness of the tiles 1, 1... Supported via the receiving brackets 3, 3 and the upper receiving brackets 4, 4 is easily adjusted.

  According to the tile mounting structure on the tunnel wall surface of the second embodiment, the detachment prevention pieces 184 are formed on both side portions of the upper side locking portion 182 and the lower side locking portion 183 which are formed on the receiving piece locking piece 18. , 184, 185, 185, so that the lower brackets 3 and 3 and the upper brackets 4 and 4 on both sides are reliably prevented from coming off even when subjected to vibration such as an earthquake, as in the first embodiment. The support of the tile 1 is ensured.

  According to the tile mounting structure on the tunnel wall surface of the second embodiment, the lower receiving metal fittings 3 and 3 and the upper receiving metal fittings 4 and 4 both have the engaging grooves 35 and 45 that open to the lower portion. The piece 18 is engaged with the upper-stage engagement portion 182 or the lower-stage engagement portion 183, and for the same reason as described in the first embodiment, the floating and the detachment due to the floating are prevented.

<Example 3>
The tile mounting structure on the tunnel wall surface of the third embodiment is an example in which a floating prevention piece (floating prevention member) 19 is used instead of the elastic inclusion 10 of the first embodiment, and other configurations are the same as those of the first embodiment. All are the same. Therefore, the following description will be made with an emphasis on the anti-floating piece 19, and the description of other items will be limited to the minimum necessary. In addition, the same code | symbol shall be attached | subjected to the component same as Example 1. FIG.

  As shown in FIGS. 29 (a) to 29 (c), the anti-floating piece 19 includes a vertically long rectangular plate-like fixed piece 191 and a pair of protrusions that are bent forward at right angles from both sides of the fixed piece 191. It is composed of an interval holding portion 192 composed of side plates 1921 and 1921 and holding pieces 193 and 193 which are formed by bending the upper ends of the two side plates 1921 and 1921 constituting the interval holding portion 192 outward at right angles. is there.

  As shown in FIGS. 25 to 28, the fixing piece 191 is attached to the front surface of the fixing plate 81 of the catching piece 8 for receiving metal fittings, and is used in the central portion for the attachment. A long mounting hole 194 is opened in the direction. Further, the fixing piece 191 is usually inserted into the front surface of the fixing plate 81 of the latching piece 8 for receiving metal fitting through the vertical joint portion after setting the tiles 1 and 1 on both sides, whereby the spacing holding portion 192 is inserted. Is inserted and arranged between the engagement plates 42 of the upper receiving brackets 4 and 4 on both sides supporting the tiles 1 and 1, and the dimension therebetween is held so as not to fall below a predetermined joint dimension. Therefore, the lateral width of the fixed piece 191 is set to be slightly smaller than the width of the vertical joint, that is, the dimension between the side plates 1921 and 1921 of the interval holding portion 192.

  The fixing piece 191 described above is fixed by joining screws to the attachment long holes 194 after being joined to the front surface of the fixing plate 81 of the locking piece 8 for receiving metal fittings. In Example 3, the fixing piece 191 is simultaneously fixed not only to the fixing plate 81 but also to the coupling plate 72 of the main receiving member 7 behind it. When a screw is used for fixing, the tapping screw 20 is used, and the fixing plate 81 and the coupling plate 72 are screwed together to be coupled and fixed.

  As described above, the side plates 1921 and 1921 are bent at right angles from both sides of the fixed piece 191 so as to protrude forward, but the forward protruding dimension is limited in consideration of the required width of the holding pieces 193 and 193. And decide. This is because the two side plates 1921 and 1921 constitute not only the interval holding portion 192 but also the holding pieces 193 and 193 that are bent outward from their upper ends as described above. . The holding pieces 193 and 193 are arranged on the upper sides of the engaging plates 42 of the upper receiving metal parts 4 and 4 engaged with the lower engaging parts 83 of the receiving metal engaging pieces 8, By restricting the upward movement of the engagement plate 42, the upper receiving brackets 4 and 4 are prevented from floating, and thereby the tiles 1 and 1 to be supported are prevented from floating. It is preferable that the holding pieces 193 and 193 can hold the engaging plates 42 of the upper receiving brackets 4 and 4 with a certain wide width. This is to prevent the load from being concentrated on a narrow part when the tiles 1 and 1 are moved in the flying direction. Therefore, for example, the holding piece 193 preferably has a width that is about half or more of the dimension of the engagement plate 42 extending from the receiving bracket base 41 of the upper receiving bracket 4 in the rear direction. In Example 3, the width slightly exceeded the half. In accordance with this, the forward projecting dimensions of the side plates 1921 and 1921 correspond to this.

Accordingly, the holding pieces 193 and 193 are protruded laterally so as to be able to hold down the upper portions of the engaging plates 42 of the upper receiving brackets 4 and 4 on both sides with the above width.
The floating prevention piece 19 is made entirely of stainless steel.

  Therefore, the tile mounting structure on the tunnel wall surface of the third embodiment is the same as that of the first embodiment except for the elastic inclusion 10, and the elastic inclusion 10 is shown in FIGS. All configurations except for are created in the same manner.

  Thereafter, at each position where the catching piece for receiving metal fitting 8 is installed, the floating prevention piece 19 is fixed to the fixing plate for the holding piece for receiving metal fitting 8 through joints between adjacent tiles 1 and 1 on both sides. Insert to the front of 81. As shown in FIGS. 25 to 28, at this time, the levitation preventing piece 19 is inserted with its orientation determined so that the back surface of the fixed piece 191 can be joined to the front surface of the fixed plate 81. At this time, it goes without saying that the insertion position in the height direction is such that the two restraining pieces 193 and 193 of the engaging plates 42 of the upper receiving metal fittings 4 and 4 that support the tiles 1 and 1 on both sides. Determine to be located directly above the upper side.

  After the floating prevention piece 19 is thus positioned at a predetermined position on the front surface of the fixing plate 81 of the catching piece 8 for receiving metal fittings, the tapping screw 20 is inserted into the attachment long hole 194 from the front side of the fixing piece 191. Is inserted into the back fixing plate 81 and the connecting plate 72 of the main receiving member 7 behind it, and the fixing piece 191 is joined and fixed thereto, and the anti-lifting piece 19 is fixed at this position.

  The above is description in parts other than the peripheral part of the installation area of the tiles 1, 1,..., But in the peripheral part, the tiles 1, 1,. In some cases, it may not exist, or there may be only one of the left and right sides at the other peripheral portion. In that case, the floating prevention piece 19 will be prevented. The method of preventing the surfacing by is the same as described above.

  In this way, in this third embodiment, either or both of the movement in the floating direction and the lateral direction on the tiles 1, 1 depending on the swinging of an earthquake or the like, the cleaning work, or when an object collides with the tiles 1, 1,. Even if the above occurs, the floating prevention piece 19 in which the floating of the engaging plates 42 of the upper receiving brackets 4 and 4 that support the tiles 1 and 1 is fixed to the front surface of the fixing plate 81 of the locking piece 8 for receiving brackets. As a result, the floating is prevented and the upper receiving brackets 4, 4 that support the tiles 1, 1 are supported by the side plates 1921, 1921 of the interval holding portion 192 of the floating prevention piece 19. .. Is prevented as a whole, and the tiles 1, 1... Are always positioned at predetermined positions.

<Example 4>
The tile mounting structure on the tunnel wall surface of the fourth embodiment is an example in which the floating prevention piece (floating prevention member) 19 used in the third embodiment is used instead of the elastic inclusion 100 in the second embodiment. The configuration is all the same as in the second embodiment. Accordingly, the following description will be given with an emphasis on the usage of the anti-floating piece 19 and the explanation of other items will be limited to the minimum necessary. In addition, the same code | symbol shall be attached | subjected to the component same as Example 2. FIG.

  Therefore, the tile mounting structure on the tunnel wall surface of Example 4 has the same configuration as that of Example 2 except for the elastic inclusion 100. As shown in FIGS. All configurations except for are created in the same manner.

  Thereafter, at each position where the catching piece 18 for receiving metal fittings is installed, the anti-floating piece 19 is connected to the connecting plate for the engaging piece 18 for receiving metal fittings through joints between adjacent tiles 1 and 1 on both sides. Insert to the front of 181. As shown in FIGS. 30 to 33, at this time, the floating prevention piece 19 is inserted with its orientation determined so that the back surface of the fixed piece 191 can be joined to the front surface of the connecting plate 181. At this time, it goes without saying that the insertion position in the height direction is such that the two restraining pieces 193 and 193 of the engaging plates 42 of the upper receiving metal fittings 4 and 4 that support the tiles 1 and 1 on both sides. Determine to be located directly above the upper side.

  In this way, after the floating prevention piece 19 is positioned at a predetermined position on the front surface of the connecting plate 181 of the catching piece 18 for receiving metal fittings, the mounting strip 191 is used for the concrete from the front side of the fixing piece 191. Screws 21 are inserted and penetrated through the long hole 186 of the connecting plate 181 in the back, the slit 171 of the unevenness adjusting plate 17 and the connecting long hole 163 of the mounting plate portion 161 of the mounting bracket 16, respectively. It is screwed into the wall surface W, the fixing piece 191 is joined and fixed thereto, and the anti-floating piece 19 is fixed at this position. Prior to the installation of the levitation prevention piece 19, a pilot hole for the concrete screw 21 is opened at a corresponding position on the wall surface W using an electric drill or the like.

  The above is description in parts other than the peripheral part of the installation area of the tiles 1, 1,..., But in the peripheral part, the tiles 1, 1,. There may be cases where it does not exist, or there are cases where there is only one of the left and right sides at the other peripheral part.
