Description

  The present invention relates to a metal thin adhesion auxiliary device suitable for assisting adhesion of mortar to a concrete structure, a mortar adhesion wall using the metal thin adhesion auxiliary device, a method of installing the same, and a wall with tiled tiles and the method of application .

  Conventionally, when concrete structure is constructed, fresh concrete is poured between the two molds while maintaining the two molds facing each other at a predetermined interval with a plurality of spacer bolts. A concrete structure is built by curing and then removing the two forms.

  Moreover, since the concrete structure built in this way is in a state where only the formwork has been removed, the appearance of the surface of the concrete structure is, of course, not good.

  In order to improve the appearance, for example, when the mortar wall is formed on the surface of the concrete structure, the mortar wall is formed by applying a fresh mortar to the surface of the concrete structure and then curing it.

  Here, the mortar wall formed as described above is likely to peel off from the surface of the concrete structure when the adhesion state to the surface of the concrete structure degrades with the passage of time. .

  For this, a mortar bonding aid as described in Patent Document 1 below has been proposed. The mortar bonding aid is integrally formed of resin so as to have a truncated cone-like plugging portion and a plurality of loop-like locking portions formed on the plugging portion.

  When applying mortar as described above, for example, to a concrete construction body using the mortar adhesion aid formed in this manner, the adhesive for the plugging portion is applied to the outer peripheral surface and the bottom surface of the plugging portion After being filled, the plugging portion is embedded via a plugging portion adhesive in a cone mark formed as described below on the surface of the concrete structure. At this time, the embedding is performed so as to expose the locking portion from the surface of the body concrete.

  Here, the above-described cone mark is formed on the concrete structure as follows. That is, a connector having an external shape corresponding to a mark of a cone is provided in two molds, and thereafter, a concrete structure is formed by setting and curing green concrete in the two molds via the connectors. Form The formwork is then removed from the concrete structure together with the connector so that the concrete structure is formed to have cone marks of the shape corresponding to the connector.

  After the mortar bonding aid is embedded in the cone mark of the concrete structure as described above, when applying the fresh mortar, the green mortar is applied so that it covers the surfaces of both the mortar bonding aid and the concrete structure. Be done.

  Thus, since the green mortar is in a non-hardened state at the stage when green mortar is applied, the green mortar intrudes into the locking portion of the mortar bonding aid. Therefore, when the green mortar hardens in such a state, the mortar adhesion aid can exert an anchor effect on the mortar wall made of hardened mortar.

  However, in order to use the mortar bonding aid configured as described above for bonding green mortar to a concrete structure, as described above, a separate connector is required, and the connector used for a mold is used. The extra work of removing the concrete from the concrete structure of the formwork is required.

  In addition, after removing the connector as described above, it is necessary to attach the mortar bonding aid to the cone mark again, which is troublesome.

  Also, the connector removed as described above is discarded after being used several times. Thus, the connector suffers from the problem of environmental pollution as waste.

  For this purpose, as in the mortar adhesion auxiliary tool described in Patent Document 2 below, a disk-shaped base portion, and a large number of loop-shaped locking portions protruding in a row on the surface of the base portion. So, there is what we configured.

  The mortar bonding aid is different from a frusto-conical mortar bonding aid having a truncated cone like the mortar bonding aid described in Patent Document 1 described above, and a disc-type mortar bonding having a base portion It is an aid.

  In applying the mortar to the concrete structure as described above using the disc-type mortar bonding aid, after the concrete structure is formed by curing the green concrete as described above, the disc-type mortar bonding aid Are fastened to the concrete structure by means of screws in a state of being disposed from the back surface of the base portion to a part of the surface of the concrete structure.

  After that, a fresh mortar is applied over the surfaces of both the disc type mortar bonding aid and the concrete structure, and then hardened to form a mortar wall.

Japanese Patent Laid-Open No. 2000-45480 Patent No. 3998351

  By the way, when forming a mortar wall on the surface of a concrete structure using a disc mortar bonding aid as described above, the mortar wall is formed on the surface of the concrete structure using a truncated cone mortar bonding aid Unlike the case, of course not requiring the connector, but also the extra working steps such as the formation of the corn mark on the raw concrete by the connector, the post formation of the corn mark and the removal from the corn mark of the connector with the formwork It is not necessary at all, it is only necessary to fasten the disc type mortar bonding aid to the surface of the concrete structure.

  Further, the base portion of the disc-type mortar bonding aid is disc-shaped unlike the frusto-conical filling portion of the frusto-conical mortar bonding aid. Therefore, the disc-type mortar bonding aid is structurally superior to the frusto-conical mortar bonding aid in that it is configured to be very thin and compact as compared to the truncated cone mortar bonding aid.

  However, since the disc-type mortar bonding aid is formed of resin, it lacks in strength, so that the mortar wall may be easily peeled off or dropped.

  On the other hand, in recent years, there has been a demand to reduce the cost of fresh mortar which is a material for forming the mortar wall and its application work, as well as to prevent peeling and falling of the mortar wall well.

  In order to meet this requirement, it is desirable to make the thickness of the fresh mortar applied to the surface of the concrete structure as thin as possible, and to enhance the strength as an adhesion aid.

  In order to solve this problem, we propose an adhesion aid made of metal rather than a resin, as in the case of a disk type mortar adhesion aid, since metal has much higher strength than resin. Is considered.

  Here, even if the bonding aid is formed of metal, in order to make the thickness of the mortar wall as thin as possible, the thickness from the surface of the concrete structure as the entire structure of the bonding aid can be made. It is desirable to form as thin as possible. In addition, even if the resin-made adhesion | attachment assistance tool like the disk-type mortar adhesion | attachment assistance tool mentioned above is thinly formed in the whole structure, it will only cause the remarkable strength fall.

  Therefore, in order to cope with the above-mentioned problems, the present invention uses a metal to make the whole structure as thin as possible, and a metal thin adhesion aiding instrument, and a mortar using the metal thin adhesion aiding instrument An object of the present invention is to provide a bonded wall, a method of installing the same, and a tiled wall and a method of installing the same.

  The outer ring 130 is supported by the plurality of connecting pieces 120 so as to be parallel to the surface of the inner ring 110. Specifically, the outer ring 130 has the respective tip portions 123 of the plurality of connection pieces 120 at corresponding portions to the extension end portions of the respective tip portions 123 of the plurality of connection pieces 120 in the inner peripheral portion thereof. In the same plane, the extension end portions of the respective tip portions 123 are integrally formed. Thus, the outer ring 130 is supported by the plurality of connection pieces 120 so as to be parallel to the surface of the inner ring 110 as described above.

  In the first embodiment, the distance in the height direction between the surface of the outer ring 130 and the back surface of the inner ring 110 is equal to the distance H in the height direction between the surface of the tip 123 of the connecting piece 120 and the back surface of the inner ring 110 . This means that the axial thickness as the entire structure of the outer peripheral side metal thin bonding aid 100 corresponds to the height direction interval H = 2 (mm), which is very thin. This is also the basis for making the outer metal thin bonding aid 100 thin as its name suggests.

  In the first embodiment, the inner diameter D3 of the outer ring 130 is set to D3 = 28 (mm), and the outer diameter D4 of the outer ring 130 is set to D4 = 32 (mm) (see FIG. 4 and FIG. 5). In the first embodiment, the shape formed by each connecting piece 120 and the outer ring 130 has a rigidity that allows relative penetration into the green mortar, and the engagement with the mortar wall M after hardening of the green mortar Has a breaking strength capable of supporting the mortar wall M. The thickness of the outer ring 130 is the same as the thickness of the inner ring 110.

  Then, the construction method of the mortar adhesion wall S with respect to the concrete wall 10a is demonstrated with reference to FIG.

  First, in the mold installation step S1 of FIG. 6, both concrete molds (not shown) are assembled and installed so as to face each other. In addition, concrete formwork is also called molde hereafter.

  After the processing of the form setting process S1, fresh concrete is poured between the two forms in the green concrete placing process S2. Along with this, fresh concrete flows in between the two forms. Fresh concrete is concrete that has not yet been cured.

  After that, in a next ready-to-set concrete hardening waiting step S3, it waits for a predetermined waiting time until the ready-mixed concrete filling between the two formwork hardens. When the green concrete hardens in this manner, a concrete wall 10a is formed.

  Next, in the form removal step S4, both forms are removed from the concrete wall 10a. As a result, the concrete wall 10a is placed in an exposed state in which the concrete wall 10a is erected.

  Thereafter, in the metal thin adhesion assisting device assembling step S5, the five metal thin adhesion aiding devices 100 among the plurality of metal thin adhesion aiding devices 100 are surfaced on the concrete wall 10a as follows. It is assembled from the side.

  That is, four of the five metal thin bonding aids 100 of the four metal thin bonding aids 100 are the outer metal thin bonding aid 100 of the surface 11 of the concrete wall 10a at the inner ring 110, respectively. Among the concrete wall 10a, which is installed at each corner of the rectangular outline RL and the remaining one metal thin adhesion aiding device 100 is a central side metal thin adhesion aiding device 100 as the inner ring 110. It is installed in a corresponding portion of the surface 11 with respect to the center of the rectangular contour RL (see FIGS. 1 and 7).

  At this time, as illustrated in FIG. 7, the five metal thin adhesion assisting devices 100 respectively extend a plurality of connecting pieces 120 in a slanted shape outward from the surface 11 of the concrete wall 10a. The back surface of the inner ring 110 is installed on the surface 11 of the concrete wall 10 a.

  In such an installation state, as shown in FIG. 7 and FIG. 8, the washer WS shown in FIG. It is installed over the proximal end 121 of the ring 110 and the plurality of connecting pieces 120.

  In the first embodiment, the washer WS is annularly formed of, for example, stainless steel as a plain washer, and the plate thickness Z, the inner diameter Ri and the outer diameter Ro of the washer WS are each Z = 0. It is set to 8 (mm), Ri = 4.2 (mm), and Ro = 13 (mm).

  As described above, after installing the washer WS for each metal thin adhesion assisting device 100, the concrete screw SC is a hollow portion of the washer WS at the lower part of its neck as illustrated in any of FIG. 7 and FIG. And the central hole portion 111 of the inner ring 110 is fastened to the concrete wall 10 a. In addition, since the concrete wall 10a is a vertical wall, the fastening of the concrete screw SC can be performed by attaching the washer WS to the inner ring 110 and the base end portions 121 of the plurality of connecting pieces 120 in the installation state of the thin metal adhesion assisting device 100 made of metal. It is done while holding so as not to fall every time it is installed over the top.

  In this fastening, after forming the lower hole portion in the concrete wall 10a through the hollow portion of the washer WS and the central hole portion 111 of the inner ring 110 by an electric tool (not shown), the concrete screw SC is It is performed by fastening to the lower hole through the hollow portion of the washer WS and the central hole 111 of the inner ring 110.

  In such a locked state, since the inner diameter Ri of the washer WS is the same as the inner diameter of the central hole portion 111 of the inner ring 110, the concrete screw SC has the washer WS on the inner ring 110 at its head. At the outer peripheral portion of the central hole portion 111, it can be firmly assembled in a stable state to the concrete wall 10a by the washer WS and the concrete screw SC (see FIGS. 7 and 8).

  As described above, when the assembly of each of the five thin metal attachment aids 100 to the concrete wall 10a is completed, in the next green mortar coating step S6, the green mortar has a coating thickness within a predetermined coating thickness range. , For example, 3 (mm) over the entire surface 11 of the concrete wall 10a. Along with this, the applied fresh mortar is formed as a fresh mortar wall. In the present embodiment, the above-mentioned predetermined application thickness range takes into consideration the requirement to make the mortar wall M as thin as possible and that the above-mentioned predetermined height interval range is 2 ± 0.5 (mm). It is selected to be 3 ± 0.5 (mm). In addition, a raw mortar means the mortar which is not yet hardened.

  At this time, the application is performed so as to cover the five thin metal adhesion aiding devices 100 on the surface of the concrete wall 10a with fresh mortar. Therefore, each metal thin adhesion auxiliary tool 100 will be embedded in the green mortar on the surface 11 of the concrete wall 10a.

  Along with this, the green mortar passes between the adjacent connection pieces 120 of the plurality of connection pieces 120 of each thin metal attachment aid 100 and penetrates to the back side thereof, and the outer ring 130 and the plurality of connections Penetration between the piece 120 and the surface 11 of the concrete wall 10a. Thus, the green mortar extends between the plurality of connecting pieces 120 and outer ring 130 of each of the five thin metallized bonding aids 100 and the surface 11 of the concrete wall 10a. Thus, the green mortar is formed as the green mortar wall.

  Thereafter, in the next fresh mortar hardening waiting step S7, it waits for a predetermined time until the green mortar wall consisting of the fresh mortar applied to the surface 11 of the concrete wall 10a hardens as described above. Accordingly, when the green mortar wall hardens, a mortar wall M is formed on the surface 11 of the concrete wall 10a as shown in FIG. 2 by hardening the green mortar wall.

  As described above, in the first embodiment, since each of the plurality of thin metal adhesion assisting devices 100 is formed of stainless steel, each of the metal thin adhesion assisting devices 100 is a resin adhesive Even with the aids, it has very high mechanical strength and can maintain its original function without rusting for a long time.

  Here, the distance (height direction distance) between the back surface of the inner ring 110 and the surface of the outer ring 130 of each thin metal attachment aid 100 is 2 (mm), which is very narrow. This means that the axial thickness of the overall structure of each thin metal attachment aid 100 is very small. In other words, this means that the thin metallic adhesion aid 100 can be provided as a very thin adhesion aid.

  In addition, as described above, the mortar adhesion wall S is mounted on the surface 11 of the concrete wall 10a, and the surface of the concrete wall 10a through the plurality of metal thin adhesion assistants 100 and the plurality of metal thin adhesion assistants 100. It is comprised by 11 and the mortar wall M formed.

  Here, in the mortar adhesive wall S, the mortar is tightly entangled with the inner ring 110, the connection pieces 120 and the outer ring 130 in each metal thin adhesion auxiliary tool 100 having the above-mentioned configuration. , Engaged strongly.

  Moreover, since each metal thin adhesion assisting device 100 is formed of stainless steel as described above, it has very high mechanical strength as compared with the resin adhesion assisting device.

  Therefore, each metal thin adhesion assisting device 100 can well prevent peeling and peeling of the mortar wall M from the concrete wall 10a for a long time.

  Further, in the mortar adhesion wall construction method using the plurality of thin metal adhesion aiding instruments 100 configured as described above, as described above, the concrete wall 10a is hardened by the hardening of the fresh concrete being driven between the two formwork. After being formed, after the two molds have been removed, five metal thin bonding aids 100 of the plurality of metal thin bonding aids 100 are applied to the surface 11 of the concrete wall 10a as described above. While being distributed and disposed at each corner and central portion of the rectangular outline RL, each inner ring 110 is provided on the surface 11 of the concrete wall 10a with each concrete screw SC via each washer WS. Be fastened. The plurality of metal thin adhesion assisting devices 100 are the five metal thin adhesion aiding assistants described above for each of the remaining five metal thin adhesion aiding appliances 100 other than the five metal thin adhesion aiding appliances 100 described above. It is fastened to the surface 11 of the concrete wall 10a in the same manner as the device 100.

  Thereby, in the plurality of metal thin adhesion assisting devices 100, for each of the five metal thin adhesion aiding devices 100, each metal thin adhesion aiding device 100 is a concrete screw SC through the washer WS in the inner ring 110. Is firmly assembled to the surface of the concrete wall 10a. In such a state, fresh mortar is applied to the surface 11 of the concrete wall 10a as described above to be formed as a fresh mortar wall, so that the fresh mortar wall is made of each metal on the surface of the concrete wall 10a. The plurality of connecting pieces 120 and the outer ring 130 of the low-profile bonding aid 100 can be firmly engaged.

  Here, for each metal thin adhesion assisting device 100, the plurality of connection pieces 120 are directed outward at equal angular intervals from the outer peripheral portion of the inner ring 110 at the proximal end portion 121 respectively. It is radially extended, and is inclinedly extended at a predetermined inclination angle α = 45 degrees from the extension end of the corresponding proximal end 121 to the surface side of the inner ring 110 at the inclined portion 122, and At the tip end portion 123, it extends outward from the extension end of the corresponding inclined portion 122 so as to be parallel to the surface of the inner ring 110. Then, the outer ring 130 is supported by the respective distal end portions 123 by the plurality of connection pieces 120 as described above.

  As described above, in addition to the plurality of connecting pieces 120 being bent and formed, the inclination angle α of the inclined portion 122 of each connecting piece 120 is 45 degrees, and The height direction interval of the outer ring 130 described above is made very narrow at H = 2 (mm) so as to be very thin at the axial thickness.

  Thus, the thickness of the mortar wall M can be as thin as 3 (mm) because each metal thin adhesion assisting device 100 is very thin. Also, even if the thickness of the mortar wall M is reduced as described above, the plurality of connecting pieces 120 of the mortar wall M and the mortar wall portion between the outer ring 130 and the surface of the concrete wall 10a are as described above. A plurality of connection pieces 120 and an outer ring 130 can be firmly held on the basis of the inner ring 110 firmly fixed to the surface of the concrete wall 10a. As a result, the adhesion assisting power to the mortar wall M by the plurality of connection pieces 120 and the outer ring 130 can be generated well in a well-balanced manner on the basis of the inner ring 110 for each metal thin adhesion auxiliary tool 100.

  As a result, as described above, even if the plurality of thin metal attachment aids 100 are thin and the mortar wall M is thin accordingly, each metal thin bond for each of the five metal thin attachment aids 100 The adhesion of mortar wall M to concrete wall 10a is well assisted by connection pieces 120 and outer ring 130 of auxiliary tool 100 with reference to inner ring 110, and the adhesion of mortar wall M to concrete wall 10a, ie, The anchor effect can be enhanced well in a balanced manner.

  Further, as described above, since each metal thin adhesion assisting device 100 is unlikely to rust and deteriorate over time, the adhesion assisting power of each metal thin adhesion assisting device 100 to the mortar wall M is excellent over a long period of time. It can be maintained.

Further, since the plurality of thin metal adhesion assisting devices 100 have the configuration as described above, the workability can be improved without the need for repeating the removing operation and the new attaching operation as described in the prior art. As a matter of course, it is possible to prevent in advance the occurrence of environmental pollution problems resulting from disposal as described in the prior art.
Second Embodiment
In FIGS. 10 and 11, the second embodiment of the present invention is shown as an example of applying a tiled wall to a concrete structure 10.

  In the second embodiment, the tile attachment wall (hereinafter also referred to as tile attachment wall Sa) corresponds to the plurality of metal thin adhesion assisting devices 100 described in the first embodiment and the first embodiment. A mortar wall Ma replacing the mortar wall M described above and a tile wall 200 are provided.

  Here, in the second embodiment, a plurality of thin metal adhesion assisting devices 100 assist the adhesion maintenance of the mortar wall Ma with the tile wall 200 to the concrete wall 10a described in the first embodiment. Play the role of

The mortar wall Ma is formed of a mortar (hereinafter also referred to as a fiber-containing mortar) in which reinforcing fibers within a predetermined number range are uniformly mixed. In the present embodiment, the predetermined number range described above is in the range of tens of thousands to hundreds of thousands per 1 (cm ³ ) so as to plate the mortar wall with fibers. In the present embodiment, the plate-like formation of the fiber-containing mortar wall helps to prevent the cracking of the fiber-containing mortar wall. In addition, when the mortar of the fiber-containing mortar is in a raw state, the fiber-containing mortar is referred to as a fiber-containing fresh mortar. Along with this, when the raw mortar is in a hardened state in the fiber-containing fresh mortar, it is simply referred to as a fiber-containing mortar.

  In the second embodiment, for example, polypropylene short fibers are adopted as the above-mentioned reinforcing fibers. In addition, the length of the said short fiber is a length within the range of 2 (cm)-30 (cm), for example.

  Thus, the reason why polypropylene short fibers are adopted as reinforcing fibers is as follows.

  Conventionally, a fiber-containing mortar in which reinforcing fibers are mixed into mortar is used as a mortar wall forming material in consideration of the fact that when the tile is attached to a mortar wall, the tile is heavy because the tile is heavy. The According to this, the mortar wall bears the weight of the tile and is difficult to peel off. Here, long fibers are conventionally employed as the reinforcing fibers.

  However, since the metal thin adhesion aiding apparatus according to the second embodiment is made of metal as its name suggests, it has high strength. This means that the mortar adhesion assisting power of the metal thin adhesion assisting device is greatly enhanced as compared with the resin adhesion assisting device. Thus, the prevention of mortar wall spalling due to the weight of the tile can be significantly improved as compared to the case of a resin bonding aid.

  In addition, since the thin metal adhesion assisting device is formed thin as described above, the thickness of the mortar wall can be thinner than in the prior art. This means that the coating amount and weight of the mortar wall can be reduced.

  In addition, it has been verified that reinforcing fibers in the fiber mortar can be sufficiently prevented from peeling off the mortar wall due to the weight of the tile even if they are not long fibers as in the past and are made into short fibers.

  Because of this, in the second embodiment, the reinforcing fibers are short fibers. Moreover, it is because the fiber of the said polypropylene intertwines with a mortar favorably as employ | adopting the fiber of a polypropylene as a short fiber. Accordingly, the mortar wall Ma adopts a short fiber of polypropylene as a reinforcing fiber number within the above-mentioned predetermined number range and a mortar formed by uniformly mixing the short fiber (hereinafter referred to as a short fiber-containing mortar) It is formed with. In addition, the fresh mortar formed by mixing the said short fiber is also called a short fiber-containing fresh mortar. Along with this, the short fiber-containing fresh mortar is also referred to as a short fiber-containing mortar after curing of the fresh mortar. Also, the mortar wall Ma is hereinafter also referred to as a fiber-containing mortar wall Ma.

  The tile wall 200 is configured by arranging a plurality of tiles 200 a in a wall shape, and the tile wall 200 is adhered to the fiber-containing mortar wall Ma from the surface side thereof by pressing via an adhesive. The bonding of the tile wall 200 to the fiber-containing mortar wall Ma is not limited to using an adhesive, and may be performed by any method among conventional bonding methods.

  Ceramics, concrete, marble and the like can be mentioned as a material for forming the tile, but in the second embodiment, a rectangular plate-like marble is adopted as a material for forming the tile 200a. The thickness of the tile 200a is, for example, 10 (mm), and the length in the longitudinal direction and the lateral direction of the tile 200a is, for example, 450 (mm). In addition, the weight of the tile 200a is, for example, about 25 (kg).

  Next, in the second embodiment, a method of installing the tile-pasted wall Sa on the concrete wall 10a will be described with reference to FIG.

  At this time, the application is performed so as to cover the five thin metal adhesion aiding devices 100 on the surface of the concrete wall 10a with a short fiber-containing fresh mortar. Accordingly, each metal thin adhesion assisting device 100 is embedded in the short fiber-containing fresh mortar on the surface 11 of the concrete wall 10a.

  Then, the short fiber-containing green mortar passes between the adjacent connection pieces 120 of the plurality of connection pieces 120 of each thin metal attachment aid 100 and penetrates to the back side thereof, and the outer ring 130 and the plurality of It infiltrates between the connecting piece 120 and the surface 11 of the concrete wall 10a. Accordingly, the short fiber-containing green mortar extends between the plurality of connecting pieces 120 and outer rings 130 of each of the five metal thin bonding aids 100 and the surface 11 of the concrete wall 10a. Thereby, the short fiber-containing fresh mortar is formed as a short fiber-containing fresh mortar wall.

  Along with this, the short fiber-containing green mortar, in addition to engaging with the inner ring 110, the plurality of connecting pieces 120 and the outer ring 130 of each metal thin adhesion auxiliary instrument 100, with the green mortar, Thus, the inner ring 110, the plurality of connection pieces 120 and the outer ring 130 of each thin metal attachment aid 100 are engaged in a tangled manner. For this reason, the engagement of the short fiber-containing fresh mortar wall with each metal thin adhesion auxiliary tool 100 can be greatly enhanced.

  After that, in the next short fiber-containing fresh mortar curing waiting step S9, the short fiber-containing fresh mortar wall consisting of short fiber-containing fresh mortar applied to the surface 11 of the concrete wall 10a as described above is cured for a predetermined time Wait for a while. Along with this, when the short fiber-containing fresh mortar wall hardens, a fiber-containing mortar wall Ma is formed on the surface 11 of the concrete wall 10a as shown in FIG.

Because of the firm engagement, the adhesion assisting force to the surface 11 of the concrete wall 10a of each metal thin adhesion aiding instrument 100 by the fiber-containing mortar wall Ma can be greatly enhanced. As a result, the fiber-containing mortar wall Ma can be well adhered and held to the concrete wall 10 a under the strong adhesion assisting force by each metal thin adhesion assisting device 100.

  Thus, when the processing of the short fiber-containing fresh mortar setting step S9 ends, the tile wall 200 is attached to the fiber-containing mortar wall Ma in the next tile attaching step S10.

  Here, the tile adhesive is uniformly applied to the surface of the fiber-containing mortar wall Ma with a thickness of about several millimeters. After that, the tile wall 200 is attached. A plurality of tiles 200a are crimped onto the surface of the fiber-containing mortar wall Ma one by one in a matrix. At this time, a liquid tile joint material is filled in the groove portion formed between the adjacent tiles 200a. Thereby, the prevention of the occurrence of a defect due to the thermal expansion of each tile 200a and the improvement of the design can be secured. The attaching process of the tile wall 200 is not limited to the attaching process as described above, and may be any attaching process.

  Thus, the tile wall 200 is formed by sequentially pressing the plurality of tiles 200a and filling and curing the joint material as described above. The tile wall 200 thus formed can be adhered and held well to the surface 11 of the concrete wall 10a through the fiber-containing mortar wall Ma.

It is firmly engaged with the inner ring 110, the plurality of connection pieces 120 and the outer ring 130.

  Moreover, as described above, the mechanical strength of each metal thin adhesion assisting device 100 is high. Therefore, in the tile attachment wall Sa, the fiber-containing mortar wall Ma is independent of the weight of the tile wall 200, and along with each tile wall 200, the surface of the concrete wall 10a for a long time by the metal thin adhesion aiding instrument 100. Peeling or peeling off from 11 can be well prevented.
